The volume of the tank that will be filled with water through which the given relation is satisfied is [tex]22.5ft^{3}[/tex]
What about volume of cuboid?
The volume of a cuboid is the amount of space occupied by the three-dimensional solid figure known as a cuboid. A cuboid is a box-shaped object with six rectangular faces, where each face has a pair of parallel sides, and opposite faces are equal in size and shape.
The formula for calculating the volume of a cuboid is:
Volume = length x width x height
where length, width, and height are the three dimensions of the cuboid.
The unit of measurement for the volume of a cuboid will depend on the unit of measurement used for each dimension. For example, if the length, width, and height are measured in centimeters, then the volume of the cuboid will be expressed in cubic centimeters (cm³). Similarly, if the dimensions are measured in meters, the volume will be expressed in cubic meters (m³).
According to the given information:
As, we know that volume of cuboid is = length x breath x height
Here, length = 5 feet, breath = 3 feet and height = 1.5 feet
Volume of the aquarium = 5 x 3 x 1.5 = [tex]22.5ft^{3}[/tex]
So, the given result is [tex]22.5ft^{3}[/tex]

A police car is located 40 feet to the side of a straight road.
A red car is driving along the road in the direction of the police car and is 140 feet up the road from the location of the police car. The police radar reads that the distance between the police car and the red car is decreasing at a rate of 85 feet per second. How fast is the red car actually traveling along the road?
The actual speed (along the road) of the red car is feet per second
The actual speed (along the road) of the red car is 8.37 feet per second
To solve this problem
Let's call the distance between the police car and the red car "x" at time t. Then, we know that:
x^2 = 40^2 + (140 - vt)^2
Where
v is the velocity of the red car (in feet per second) t is timeWe are given that dx/dt (the rate at which x is decreasing) is -85 ft/s, so:
d/dt [x^2] = d/dt [40^2 + (140 - vt)^2]
2x(dx/dt) = 0 - 2v(140 - vt)
Substituting dx/dt = -85 and solving for v, we get:
2x(−85) = −2v(140−vt)
−170x = −280v + 2v^2t
v^2t = 140v - (85/2)x
Now, we can differentiate the equation x^2 = 40^2 + (140 - vt)^2 with respect to time to get:
2x(dx/dt) = 2(140 - vt)(-v)
Substituting dx/dt = -85 and solving for x, we get:
-170x = -2v(140 - vt)
x = (140v - vt^2)/85
Substituting this expression for x into the equation we derived earlier, we get:
v^2t = 140v - (85/2)((140v - vt^2)/85)
v^2t = 140v - 70(2v - t^2)
v^2t = 140v - 140v + 70t^2
v^2t = 70t^2
v = sqrt(70t^2)/t = sqrt(70) = 8.37 ft/s (rounded to two decimal places)
Therefore, the actual speed (along the road) of the red car is 8.37 feet per second

the angle of elevation from the horizontal to the sun is 38°. How long of a shadow would a 32 foot tree make at this time?
The length of the shadow would be approximately 41.7 feet if the angle of elevation from the horizontal to the sun is 38° at this time.
If the angle of elevation from the horizontal to the sun is 38°, then the tangent of that angle is equal to the opposite side (the height of the tree) divided by the adjacent side (the length of the shadow).
Therefore, we can set up the equation using trigonometric function tangent as,
tan(38°) = height of tree / length of shadow
Solving for the length of the shadow, we get:
length of shadow = height of tree / tan(38°)
Plugging in the given height of the tree (32 feet) and using a calculator to find the tangent of 38°, we get:
length of shadow = 32 / tan(38°) = 41.7 feet (rounded to one decimal place)
Therefore, the length of the shadow would be approximately 41.7 feet at this time.

Betty has 30 mls of cough medicine with breakfast.
She drinks half of her 4 ounce orange juice, and 25% of her 8 oz cup of coffee. How many mls total
did she consume?
Betty consumed a total of 148.294 milliliters of liquid with her breakfast.
To solve this problemWe can change the volumes of the coffee and orange juice to milliliters so that all of the measurements are in the same unit:
4 ounces = 4 * 29.5735, = 118.294 ml.
8 ounces = 8 x 29.5735, = 236.588 ml.
Half of Betty's 4-ounce glass of orange juice, or:
1/2 * 118.294 mls = 59.147 mls
She consumed 25% of her 8-ounce coffee, which is :
0.25 * 236.588 mls = 59.147 mls.
So, in total, Betty consumed:
30 mls of cough medicine + 59.147 mls of orange juice + 59.147 mls of coffee = 148.294 mls
Therefore, Betty consumed a total of 148.294 milliliters of liquid with her breakfast.

Hannah is working in England for 3 months on a project for her company. One weekend Hannah decides to go to France with her car on the ferry, then explore the French countryside. In England, speed limit signs are posted in miles per hour (mph) and Hannah's rental car only shows the speed in miles per hour. In France, speed limit signs are posted in kilometers per hour (kph). Hannah looks up the conversion and learns that 1 kph = 0.62 mph.
On the road that Hannah is currently on, the posted speed limit is 130 kilometers per hour. What is the maximum whole-number speed, in miles per hour, that Hannah can drive without exceeding the speed limit?
A. 82 mph
B. 79 mph
C. 209 mph
D. 80 mph
Answer:
To convert kilometers per hour to miles per hour, we need to multiply by 0.62. Therefore, to find the maximum speed that Hannah can drive without exceeding the speed limit of 130 kilometers per hour, we can multiply 130 by 0.62:
130 km/h * 0.62 = 80.6 mph
Since Hannah needs to stay within the speed limit, the maximum whole-number speed she can drive is 80 mph, which is option D.

Find the equation of a line parallel to 5x+y=5 that passes through the point (8,-9)
Answer:
y = -5x + 31
Step-by-step explanation:
To find the equation of a line parallel to the line 5x + y = 5, we first need to rearrange it in slope-intercept form, which is
y = -5x + 5. (We see that the slope of this line is -5)
A line parallel to this line will have the same slope of -5. Now, we need to find the equation of a line that passes through the point (8,-9) with slope -5.
We can use the point-slope form of the line to find the equation. The point-slope form of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
Substituting the values we have, we get:
y - (-9) = -5(x - 8)
Simplifying this equation, we get:
y + 9 = -5x + 40
y = -5x + 31
Therefore, the equation of the line parallel to 5x + y = 5 that passes through the point (8, -9) is y = -5x + 31.

Only 17 is a solution of the equation 3q = 51 among the values in the set {15, 16, 17}.
How to find out if each value in the set is a solution of the equation?To check if a value is a solution of the equation 3q = 51, we substitute the value for q and check if the equation is true.
Let's check each value in the set {15, 16, 17}:
For q = 15, 3q = 3(15) = 45, which is not equal to 51. Therefore, 15 is not a solution of the equation 3q = 51.
For q = 16, 3q = 3(16) = 48, which is not equal to 51. Therefore, 16 is not a solution of the equation 3q = 51.
For q = 17, 3q = 3(17) = 51, which is equal to 51. Therefore, 17 is a solution of the equation 3q = 51.
Therefore, only 17 is a solution of the equation 3q = 51 among the values in the set {15, 16, 17}.

Juan catches 80% of the passes thrown to him in football. If the quarterback throws to him 15 times during a game, what is the probability he will catch atleast 10 of them?
the probability that Juan will catch at least 10 passes out of 15 is approximately 0.987.
The binomial distribution, which models the number of successful trials (catches) in a certain number of independent trials (passes thrown), can be used to solve this problem.
The likelihood of not catching a pass is 0.2, but the likelihood of catching one is 0.8. The likelihood of catching at least 10 passes out of 15 can be calculated as follows:
P(X >= 10) equals P(X = 10) plus P(X = 11). + ... + P(X = 15)
where X is how many of the 15 passes were intercepted.
The probability of catching precisely k passes out of n can be calculated using the binomial distribution formula:
P(X = k) = (n choose k) × p²k × (1 - p)²(n-k)
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n distinct items.
Plugging in the values for n = 15, p = 0.8, and k = 10, 11, 12, 13, 14, and 15, we get:
P(X >= 10) = P(X = 10) + P(X = 11) + ... + P(X = 15)
= (15 choose 10) × 0.8²10 × 0.2²5 + (15 choose 11) × 0.8²11 × 0.2²4 + ... + (15 choose 15) × 0.8²15 × 0.2²0
≈ 0.987
Therefore, the probability that Juan will catch at least 10 passes out of 15 is approximately 0.987.

An air traffic controller is tracking two planes. To start, Plane A is at altitude of 2639 feet and Plane B is just taking off. Plane A is gaining altitude at 35.25 feet per second and Plane B is gaining altitude at 80.75 feet per second
How many seconds will pass before the planes are at the same altitude?
What will their altitude be when they're at the same altitude?
Answer:
Step-by-step explanation:
To find the number of seconds it will take for the planes to be at the same altitude, we need to set the altitude equations for both planes equal to each other and solve for time:
2639 + 35.25t = h (altitude equation for Plane A)
0 + 80.75t = h (altitude equation for Plane B)
where h is the altitude of both planes when they are at the same altitude, and t is the number of seconds that have passed.
Setting the two equations equal to each other and solving for t, we get:
2639 + 35.25t = 80.75t
45.5t = 2639
t = 58
Therefore, it will take 58 seconds for the planes to be at the same altitude.
To find their altitude at that time, we can substitute t = 58 into either of the altitude equations and solve for h:
2639 + 35.25t = h
2639 + 35.25(58) = h
h = 4818.5
Therefore, when the planes are at the same altitude, their altitude will be approximately 4818.5 feet.

How to explain the functionReiterating the same statement without reiteration, it is observed that f'(x) equals ƒ""(x), ultimately resulting in a value of 6. Subsequently, we can derive a complete expression for f(x) where C represents an integration constant.
It should be noted that to find this constant, since f(-1) = 2, plugging in x as -1 and f(x) as 2 into the above equation results in:
2 = 6(-1) + C

There are 7 choices for the first spot.
4 choices for the second spot. And 7 choices for the third spot, which cannot be 6,7,8--so it can be 0,1,2,3,4,5 or 9 (7choices)
7 × 4 × 7 is 196
There are 196 possibilities for the three digit area code with this plan.
A scatter plot is shown on a coordinate plane. The x-axis is numbered 0 to 15 and the y-axis is numbered from 2 to 26 in increments of 2. Points shown are located at (7, 2), (9, 1), (11, 3), (7, 6), (5, 8), (8.5, 8), (3, 12), (6, 13), and (4, 16). A line of best fit goes through points (5, 12) and (9, 4) and is extended to show it approaching the points (0, 22) and (11, 0).
Which equation represents the line of best fit?
The equation represents the line of best fit is y = -2x + 22.
What is an equation?A mathematical statement that represents a relationship between two or more quantities is typically expressed using symbols, numbers, and mathematical operations. Equations are used to express mathematical relationships, make predictions, and solve problems. An equation typically consists of an expression on each side of an equal sign (=), indicating that the values on both sides are equivalent.
According to the given information:
To determine the equation of the line of best fit in the scatter plot, we can use the slope-intercept form of a linear equation, which is given by:
y = mx + b
where m is the slope and b is the y-intercept.
Given that the line of best fit goes through points (5, 12) and (9, 4), we can calculate the slope (m) using the formula:
m = [tex]\frac{(y_{2}-y_{1})}{(x_{2}-x_{1} ) }[/tex]
Plugging in the values from the given points, we get:
m = [tex]\frac{(4-12)}{(9-5)}[/tex]
m = -8 / 4
m = -2
So, the slope of the line of best fit is -2.
Next, we can substitute the slope and one of the given points (5, 12) into the slope-intercept form to solve for the y-intercept (b):
12 = -2(5) + b
12 = -10 + b
b = 12 + 10
b = 22
So, the y-intercept of the line of best fit is 22.
Thus, the equation of the line of best fit is:
y = -2x + 22.
