9. The amount of water used by a washing
machine varies directly with the weight of the
load being washed. The washing machine uses
28 gallons to wash 7 pounds of clothing. How
many gallons of water will the machine
use to wash 24.5 pounds of laundry?

If the ball drops 80 meters in the 4 seconds, the time it takes the ball to drop in the next 8 seconds is; 720 meters

We are told that a ball dropped vertically falls a distance of d in t seconds and that d is directly proportional to the square of t. Thus;

D ∝ t²

Thus;

D = kt²  

where d is the constant of proportionality.

We are given that D = 80 m when t = 4 seconds and as such we have;

80 = k*4²

k = 80/16

k = 5

Therefore, the equation of motion is;

D = 5t²

When t = 8 + 4 = 12 seconds, we have;

D = 5 * 12²

D =  5 * 144

D =  720 m

Therefore, the distance the ball drops in the next 8 seconds

= 720 - 80

= 640 m.

For the given,  F, G and H are the midpoints of the sides of ΔJKL, FG = 37, KL = 48, and GH = 30, then measure of FH = 24, measure of JL = 74, measure of KJ = 60 and measure of FJ = 30.

As given in the question,

F, G, and H are the midpoints of the sides of ΔJKL.

F is the midpoint of KJ, G is the midpoint KL, H is the midpoint of JL

Measure of the required sides are as follow:

FH = (KL / 2)                         (by midpoint theorem)

     = (48/2)

     = 24

JL = 2 x FG             (by midpoint theorem)

   = 2 x 37

   = 74  

KJ = 2 x GH             (by midpoint theorem)

    = 2 x 30

    = 60

FJ = GH = 30            (by midpoint theorem)

Therefore, for the given,  F, G and H are the midpoints of the sides of ΔJKL, FG = 37, KL = 48, and GH = 30, then measure of FH = 24, measure of JL = 74, measure of KJ = 60 and measure of FJ = 30.

The probability of selecting a female student with long hair is 45%

Let there be a total of 100 students in the class

Since 60% of the students are female, therefore out of 100 students 60 will be female students

Now, out of these 60 students, 75% have long hair, As a result, = 75% of 60 = 45 female students will have long hair

Probability of selecting female student with long hair = Number of female students with long hair/ Total number of students in the class

= 45/100

So, there is a 0.45 or 45% chance that a female student with long hair is selected

The table has an average rate of change of 3

The table represents the given parameter

From the table, we have the following interval is given as

[3, 7]

This can be rewritten as

x = 3 to x = 7

From the attached table, we have

f(3) = 7

f(7) = 19

The average rate of change of the function is then calculated as

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [19 - 7]/[7 - 3]

Evaluate

Rate = 3

Hence, the average rate of change is 3

Answer:

Step-by-step explanation:

The solution to the questions are

The general formula is given as

A = Pe^rt

In this case, we have

P = Initial number of people

r = rate

t = time

From the question, we have

P = 8

r = 12% = 0.12

So, we have

A = 8 * e^0.12t

This means that t = 5

So, we have

A = 8 * e^(0.12 * 5)

Evaluate

A = 15

This means that A = 3,700,00

So, we have

8 * e^0.12t = 3,700,00

Divide by 8

e^0.12t = 46250

Take the logarithm of both sides

0.12t = log(46250)

This gives

0.12t = 4.7

Divide

t = 39

There are 3 teaspoons in a tablespoon, 15 teaspoons to tablespoons using a ratio table and using a conversion factor will be total as 5 tablespoons.

The consistent relationship between two values is shown in a ratio table. A rate is a unique ratio that is used to compare two quantities with different units of measurement. There are various ways to examine a ratio table.

Equivalent ratios between two quantities are displayed in ratio tables. In order to find an equal ratio, you can make a ratio table by multiplying (or dividing) the quantities in the ratio by the same number.

You can use a ratio table to determine equal ratios and solve difficulties.

A conversion factor is a kind of number that is used to multiply or divide one set of units into another.

If any kind of a conversion is required, it must be done using the proper and correct conversion factor to get an identical value. For instance, 12 inches equals a total of one foot when converting between inches and feet.

The circumference of circle with radius 9.7inch is 60.916 inch.

The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.

A circle is a closed round object whose border points are all equally spaced apart from the center, which is a fixed point.

Given that :the circle with a radius of 9.7 inches

The slope of g(x) is [tex]\frac{-2}{5}[/tex] times the slope of f(x)

The x-intercept of f(x) is 8 more than the y-intercept of g(x)

As x approaches -∞, f(x) approaches ∞ and g(x) approaches -∞

Given,

f(x) = 10-5x

g(x) = -6+2x

The slope of f(x) = -5

The slope of g(x) = 2

Hence the slope of g(x) is [tex]\frac{-2}{5}[/tex] times slope of f(x)

For x-intercept assign zero value to f(x). Thus,

10-5x = 0

=> x = 2

So intercept of f(x) = 2

y-intercept of g(x) = -6

Hence x-intercept of f(x) is 8 more than y-intercept of g(x)

As x approaches -∞, f(x) = 10-(5 times (-∞)) = ∞

As x approaches -∞, g(x) = -6 + 2x = -6 + 2(-∞) = -∞
