What is the solution Ofsimultaneous equations 5x 3y 8 and 3x Y 2?

The velocity of Rosie when running is 2 meters per second

From the question, we have the following parameters that can be used in our computation:

Time = 1/3 of 78 seconds

Distance covered = 52 meters

The velocity can be calculated using the following equation

Velocity = Distance covered/Time

Substitute the known values in the above equation, so, we have the following representation

Velocity = 52/(1/3 * 78)

Evaluate the quotient

Velocity = 2

Hence, the velocity is 2 meters per second

No , cousin is not correct because when 5,953 is rounded  to the nearet hundred the value should be 6000 .

Given :

What is rounding to the nearest hundred ?

Rounding a number to the nearest hundred means to write down the multiple of 100 that is nearest to the number .

so here given number = 5,953

so here the number 53 is greater than 50 .

We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

Answer:

A cuboid is a 3-dimensional shape with six rectangular faces, four of which are the sides or lateral faces, and the other two are the base and the top. To solve the problem, we can first find the perimeter of the base of the cuboid by dividing the lateral surface area by the height. In this case, the perimeter of the base is 26 cm.

To find the dimensions of the base, we can set up an equation using the given information. Let x be one of the sides of the base, and let y be the other side. Since one of the sides is 3 cm smaller than the other, we can write the equation as:

x + x - 3 + x + x - 3 = 26 cm

We can simplify the equation by combining like terms:

4x - 6 = 26 cm

Next, we can solve the equation by adding 6 to both sides and then dividing by 4:

4x = 32 cm

x = 8 cm

Therefore, the dimensions of the base of the cuboid are 8 cm x 11 cm (since one side is 3 cm smaller than the other). The perimeter of the base is 26 cm, and the height of the cuboid is 10 cm.

Answer:

(b) mean=95, standard deviation=7.2.

Step-by-step explanation:

To find the new mean and standard deviation, we first need to apply the transformation to the original mean and standard deviation.

The new mean is given by: x*=65+0.6x

Substituting in the original mean of 50, we get: x*=65+0.6(50) = 95

The new standard deviation is given by: s*=0.6s

Substituting in the original standard deviation of 12, we get: s*=0.6(12) = 7.2

Therefore, the new mean and standard deviation are (b) mean=95, standard deviation=7.2.

From the proof below, we have been able to prove that IK bisects ∠HIJ by CPCT postulate

Congruent angles are defined as angles that have equal measure.

Now, we are given that;

IK bisects ∠HKJ

HK ≅ JK

Thus, since IK bisects ∠HKJ, then it means that by definition of angle bisector that;

∠HKI = ∠JKI

Now, we are also told that HK ≅ JK.

Now, by reflexive property of congruence, we can say that IK is congruent to itself.

Thus, we now have 2 congruent sides and an include angle and as such both triangles are congruent by SAS Congruency postulate.

Thus, we can conclude that ∠HIK = ∠JIK by CPCT which states that Corresponding parts of Congruent Triangles are congruent.

The volume of a cone is given by the formula:

V = (1/3) * π * r² * h

Where V is the volume, r is the radius, and h is the height.

In this case, we know the radius (4.96) and the volume (102), so we can use the formula to solve for the height.

Substituting the known values into the formula, we get:

102 = (1/3) * π * (4.96)² * h

Dividing both sides by (1/3) * π * (4.96)², we get:

h = 102 / [(1/3) * π * (4.96)²]

Substituting in the value for π, we get:

h = 102 / [(1/3) * 3.14 * (4.96)²]

Which simplifies to:

h = 102 / [(1/3) * 3.14 * 24.1952]

Which simplifies to:

h = 102 / (0.7853 * 24.1952)

Which simplifies to:

h = 102 / 19.1268

Which is approximately 5.33.

Therefore, the estimated height of the cone is approximately 5.33.

r^2 = 4.96^2 = 24.6016  
Approximately = 24.6

π = 3.142
v = 1/3  x π x r^2 x h

The dot plots show that the lowland areas experienced significantly more rainfall than the highland area during spring storms, with a larger range and maximum rainfall.

The dot plots show the rainfall totals for several spring storms in both highland and lowland areas. The dots representing the lowland areas are more spread out and have a larger range compared to the dots representing the highland areas. This indicates that the lowland areas experienced more rainfall than the highland areas during these storms. Additionally, the maximum rainfall for the lowland areas is greater than the maximum rainfall for the highland areas, further emphasizing the difference in rainfall between the two areas. This could be due to a number of factors, such as the higher elevation of the highland areas resulting in less moisture being able to accumulate, or the lower temperature of the highland areas resulting in less evaporation and thus less rainfall. Additionally, the lower elevation of the lowland areas could result in more moisture being able to accumulate, and the higher temperature of the lowland areas could result in more evaporation, leading to increased rainfall. Regardless of the cause, the data from the dot plots clearly show that the lowland areas experienced more rainfall than the highland areas during these spring storms.

The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

Answer: 25 weeks

Step-by-step explanation:

Let W represent the number of weeks

Judy equation is

12W + 300

Cassie equation is

20W + 100

Now let's solve it! Our system of equation is

12W + 300 = 20W + 100

Subtract 300 from both sides

12W = 20W -200

Subtract 20W from both sides

-8W = -200

W = 25 weeks

So, it takes 25 weeks for Judy and Cassie to have the same amount saved.

Answer:

let judy = 300 + 12W

cassie = 100 + 20W

300 + 12W =  100 + 20W

300 - 100 = 20W - 12W

200 = 8W

W = 25

300 +  12(25) = 100 + 20(25)

300 + 300 = 100 + 500

600 = 600

Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

Step-by-step explanation:

first of all, remember for life :

the sum of all angles in a triangle is always 180°.

so, in this right-angled triangle we have therefore

180 = b + 90 + 71

b = 180 - 90 - 71 = 19°

and then regarding a and b :

the sum of all angles around a single point on one side of a line is also always 180°.

why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.

so,

a + b = 180

a + 19 = 180

a = 180 - 19 = 161°

FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.
