The time taken depends upon velocity and distance so the time taken by both balls to reach the same height will be 30 seconds.

Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.

Units of velocity are given by ⇒ meter/second

For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.

Difference between their initial height = 40 - 25 = 15 feet

It means if baseball cover x feet distance then football will cover x + 15 feet.

Now,

Time = distance covered / velocity

Since the time will be the same for both balls to meet them.

So,

Distance covered by baseball/velocity of baseball = Distance covered by football/ velocity of football

x/2.5 = (x + 15)/3

3x = 2.5x + 37.5

0.5x = 37.5

x = 75

So,

Time taken = 75/2.5 = 30 seconds.

Hence "After 30 seconds both balls will go to reach the same height".

If by eating 2 eggs and 1​ cupcake, a child consumes 571 mg of cholesterol. The amount of cholesterol that is in each​ item are; 19 mg, 276mg, 8 mg.

E + C + P = 303

Where:

Egg=E

Cupcake=C

Pizza=P

Hence,

3C + 4P =89

4P = 89-3C

P = (89-3C)/4

2E + C = 571

2E = 571-C

E = (571-C)/2

(571-C)/2 + C + (89-3C)/4 = 303

(571-C)2 + 4C + 89-3C = 303×4

(571-C)2 + 4C + 89-3C = 1212

1142 -2C + 4C + 89-3C = 1212

-C = 1212-89-1142

C =19mg (1 cupcake)

E = (571-C)/2

E= (571-19)/2

E=552/2

E= 276mg  (1 egg)

P = (89-3C)/4

P = (89-3(19))/4

P = (89-57)/4

P=32/4

P=8 mg (1 pizza)

So,

Egg=E=19 mg

Cupcake=C=276 mg

Pizza=P=8 mg

Check:

19+276 + 8 = 303 mg

Therefore If by eating 2 eggs and 1​ cupcake, a child consumes 571 mg of cholesterol. The amount of cholesterol that is in each​ item are; 19 mg, 276mg, 8 mg.

From the temperatures given, we have that:

a) The regression equation is: y = 2.91x + 64.61.

b) The predicted temperature at 2 pm is of 88 ºF.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

In the context of this problem, the input and the output are given as follows:

We have that an hour is 60 minutes, hence:

Thus the points are given as follows:

(0, 65), (0.75, 67), (1.5, 68), (2.5, 72), (3, 74), (3.75, 75), (4.5, 77), (5,80).

Inserting these points into the calculator, the equation is:

y = 2.91x + 64.61.

2 pm is 8 hours after 6 am, hence x = 8 and the predicted temperature, in ºF, is given by:

y = 2.91(8) + 64.61 = 88 ºF.

(2,3) is a solution to the system of equations.

A collection of one or more linear equations containing the same variables is known as a system of linear equations (or linear system).

Consider the system of equations,

2x - 3y = - 5                                                                                 --------(1)

4x - 4y = - 4                                                                                 --------(2)

Multiplying equation (1) with 2.

4x - 6y = - 10

4x - 4y = - 4

Now, subtracting the above equations:

4x - 6y - ( 4x - 4y) = - 10 + 4

4x - 6y - 4x + 4y = - 6

- 2y = - 6

2y = 6

y = 3

Then,

4x - 4y = - 4

4x - 4 × 3 = - 4

4x - 12 = - 4

Adding 12 on both sides of the equation,

4x - 12 + 12 = - 4 + 12

4x = 8

x = ( 8/4 )

x = 2

Therefore, (x, y) = ( 2, 3) is a solution to the system of equations.

A product is something that has undergone one or more multiplications. For instance, the mathematical formula "times equals" would be written with the terms "times," "multiplicand," and "product," respectively.

A number can be multiplied by another number to determine each of its products. For instance, 9 x 3 equals 27, so 27 is a product of 9 and 3. Each number has an infinite number of possible products because it can be multiplied by an infinite number of different numbers to produce an infinite number of results.

Triangle B is a dilation of A with approximately a scale factor of 8.

Triangle A is a dilation of B with approximately a scale factor of 1/8.

Triangle B is a dilation of C with approximately a scale factor of 3/4.

We have,

In mathematics, dilation refers to the transformation of a shape, object, or figure by uniformly scaling it up or down.

When the constant factor is greater than 1, the dilation results in an enlargement of the shape, making it larger.

Conversely, when the constant factor is between 0 and 1, the dilation leads to a reduction of the shape, making it smaller.

Now,

Triangle B is a dilation of A with approximately by a scale factor of:

Since triangle B is greater than A.

The scale factor is greater than 1.

Triangle B looks 8 times of triangle A.

So,

The scale factor is 8.

And,

Triangle A is a dilation of B with approximately by a scale factor of:

Since triangle B is smaller than A.

The scale factor is less than 1.

Triangle A looks like 12.5 % of triangle C.

12.5% = 1/8

So,

The scale factor is 1/8.

Triangle B is a dilation of C with approximately by a scale factor of:

Since triangle B is smaller than A.

The scale factor is less than 1.

Let's say,

Triangle B looks 75% of triangle C.

So,

The scale factor is 3/4.

Thus,

Triangle B is a dilation of A with approximately a scale factor of 8.
