The leaking fruit juice container will get empty in 24.24 minutes
How to estimate of the time it takes until the container is emptyconverting 2.5 quart to ounce
1 quart is equivlent to 32 fluid ounce, 2.5 quart will be ?
? = 2.5 * 32
? = 80 fluid ounces
The leakage is at 3.3 fluid ounces per minute to find how many minute it takes to leak 80 fluid ounces we calculate as below
3.3 fluid ounces = 1 minute
80 ounces = ?

Answer:
0.5867 (or 58.7%)
Step-by-step explanation:
The probability that a randomly selected student has a score between 350 and 550 is 59%.
What is z score?Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.
Given that,
The scores of the students on a standardized test are normally distributed.
Mean, μ = 500
Standard deviation, σ = 110
z score = (x - μ) / σ
For x = 350,
z = (350 - 500) / 110 = -1.36
Probability = 1 - 0.9131 = 0.0869
For x = 550,
z = (550 - 500) / 110 = 0.45
Probability = 0.6736
Probability that a randomly selected student has a score between 350 and 550 is,
P = 0.6736 - 0.0869 = 0.5867 ≈ 59%
Hence the required probability is 0.5867 or 58.67%.

Ashley has a $80 gift card to her favorite coffee shop. Each day, she uses her gift *
card to buy a coffee for $4.50, Aaron has a $60 gift card to the same coffee shop.
Each day, he uses his gift card to buy an iced tea for $2.50. For what number of
drinks purchased will Ashley's gift card balance be greater or equal to Aaron's?
Step-by-step explanation:
I assume this means that both purchase one item every day.
so, their number of purchases are the same (x).
80 - 4.5x >= 60 - 2.5x
20 - 4.5x >= -2.5x
20 >= 2x
10 >= x
our
x <= 10
after 10 purchased drinks their balances will be equal.
before that, Ashley's card balance will be greater than Aaron's.
after that, Aaron's card balance will be greater than Ashley's.
so, for up to 10 purchased drinks Ashley's card balance will be greater or equal to Aaron's.
Richard bought 3 slices of cheese pizza and 2 sodas for $8.75. Jordan bought 2 slices of cheese pizza and

• $3.25
O $5.25
• $7.75
• $17.25
The cost of 1 slice of cheese pizza and 3 sodas cost will be;
⇒ $5.25
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Richard bought 3 slices of cheese pizza and 2 sodas for $8.75.
And, Jordan bought 2 slices of cheese pizza and 4 sodas for $8.50.
Now,
Let the cost of 1 slices of cheese pizza = x
And, The cost of 1 slices of soda = y
Since, Richard bought 3 slices of cheese pizza and 2 sodas for $8.75.
Hence, We get;
⇒ 3x + 2y = $8.75 ..(i)
And, Jordan bought 2 slices of cheese pizza and 4 sodas for $8.50.
So, We get;
⇒ 2x + 4y = $8.50 ..(ii)
Multiply by 2 with (ii);
⇒ 2 (3x + 2y) = 2 × $8.75
⇒ 6x + 4y = $17.5
Subtract from (ii), we get;
⇒ 6x + 4y - 2x - 4y = $17.5 - $8.50
⇒ 4x = $9
⇒ x = $2.25
And, ⇒ 2x + 4y = $8.50
⇒ 2 × $2.25 + 4y = $8.50
⇒ $4.5 + 4y = $8.50
⇒ 4y = $8.50 - $4.5
⇒ 4y = $4
⇒ y = $1
Thus, The cost of 1 slice of cheese pizza and 3 sodas cost will be;
⇒ $2.25 + 3 × $1
⇒ $2.25 + $3
⇒ $5.25
Therefore, The cost of 1 slice of cheese pizza and 3 sodas cost will be;
⇒ $5.25

is the line through points P(-8, -10) and Q(-5, -12) perpendicular to the line through points R(9, -6) and S(17, -5) explain
Answer:
No, the lines are not perpendicularStep-by-step explanation:
Perpendicular lines have opposite-reciprocal slopes.
It means the product of the slopes is - 1.

Graph the point on the graph.
Answer:
see below
Step-by-step explanation:
To graph this equation, start at the origin (0,0) since there is not y-intercept.
Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.
Because the rise (up and down, numerator) is 1, we know that we will go up one unit.
The run (side to side, denominator) is 4, so we will go to the right 4 units.
This makes the first point (4, 1).

The yards of roadside that Ben is cleaning more than Adam is 26 yards. Sheridan is correct.
Who is correct?The first step is to determine the length of Oakley Street. Pythagoras theorem would be used to determine the length. Oakley Street is the hypotenuse of the right triangle that is formed by the streets.

A sailboat is headed due north, and its sail is set perpendicular to the wind, which is from the south of west. The component of the force of the wind in the direction of the heading is 480N, and the component perpendicular to the heading (the drift component) is 650 N. What is the force exerted by the wind, and what is the direction of the wind?
The direction of force is [tex]53.6^0[/tex] South of West and force exerted by the wind is 596.4N.
What are the component of force?
If a force acting at some angle [tex]\theta[/tex] with respect to x axis then the force can be resolved into two perpendicular forces ([tex]Fcos\theta[/tex] and [tex]Fsin\theta[/tex]). These perpendicular forces are known as component of forces.
Consider the following diagram of the sialboat.
The component of force along the heading direction is 480N and the component of force perpendicular to the heading is 650N.
If F is the foce the direction of wind then then component of force in the East direction will be [tex]Fcos\theta[/tex] and the component of force in the heading direction is [tex]Fsin\theta[/tex]. Now, take the ratio of these two compnents to find the angle [tex]\theta[/tex] as follows:
[tex]tan\theta=\frac{Fcos\theta}{Fsin\theta}\\tan\theta=\frac{650N}{480N}\\\\\theta=tan^{-1}(1.354)\\=53.6^0[/tex]
Now, calculate the force exerted by the wind. Equate the force in heading direction to find the force.
[tex]Fsin\theta=480N\\F=\frac{480N}{sin\theta}\\=\frac{480N}{sin53.6^0}\\=596.4N[/tex]
Hence, the direction of force is [tex]53.6^0[/tex] South of West and force exerted by the wind is 596.4N.

solution to make a 30% saline solution?
The required amount of 25% saline solution is 8 liters.
Finding unknown quantity using Linear equation:In mathematics, the equation that used to find an Unknow quantity is known as Linear Equation. Here we use different types of variables to represent the unknown value like x, y, z or a, b, c.. etc.
Here we have
4 liters of a 40% saline
we need to make it a 30% of saline solution by adding a mount of 25% saline solution
Let us assume that we added x L of 25% of saline solution
After adding x L of 25% saline into 4 liters of 40% saline to get 30% saline solution then the resultant solution is “x+4” liters of 30% saline.
The mathematical representation for the above line will be
⇒ x litres 25% saline + 4 litres 40% saline = (x+4) litres 30% saline
⇒ x(25%) + 4(40%) = (x+4)(30%)
⇒ 25x/100 + 4(40/100) = (x+ 4)30/100
⇒ 25x + 160 = (x +4)30
⇒ 25x + 160 = 30x + 120
⇒ 30x - 25x = 160 - 120
⇒ 5x = 40
⇒ x = 8
