Does the following table represent a proportional relationship, and if so what is the proportion of the cost for a box of cereal to the size of the box? Cost for a box of cereal \$2.20 \$2.64 \$3.30 \$4.84
Size of box (in ounces) 10 12 15 22
yes, \$0.22 per ounce
yes, \$4.55 per ounce
yes, \$0.44 per ounce
no it is not proportional

Step-by-step explanation: 2.20 divided by 10 is .22, so one ounce is 22 cents. 2.64 divided by 12 is .22, 3.30 divided by 15 is .22, and 4.84 divided by 10 is .22. All the costs are the same per ounce, so it is a proportional relationship of .22.

2000 miles increased by 33%

100%=2000
increased by 33%
100%+33%=133%=1.33

133% of 2000=1.33 times 2000=2660

The answer would be 2660 miles. 2000 X 0.33 = 660.

660 + 2000 = 2660

Given the force field F, find the work required to move an object on the given orientated curve. F=<y,x> on the parabola y=7x^2 from (0,0) to (4,112)

The force field is f=1234

×= 10 and ×= -14

Find x by simplifying both sides of the equation then isolate the variable.

|x+2| - 3 = 9

Option 1:

x + 2 - 3 = 9

x - 1 = 9    add 1

x = 9 + 1

x = 10

Option 2:

-(x+2) - 3 = 9  Distribute "-" through the parenthesis

-x - 2 - 3 = 9

-x - 5 = 9     Add 5

-x = 9 + 5

-x = 14   Multiply by -1

x = -14

the height of a football in the air t seconds after it is thrown can be modeled by the function y=-16t^2+96t+3, where y are measured in feet and t is time. What is the maximum height that the football reaches? How long did it take the football to reach the maximum height? At what times will the football be above the ground at 122 feet?

Since the function is a parabola, the maximum height would be the y-coordinate of the vertex. The x-coordinate of the vertex in standard parabolic form is
x = -b/2a.
In the problem, t would now be x.
t = -96/(2*-16) = 3*

Now that you have the time as 3 at the vertex, you can determine the height y at the vertex by substituting it in.
y = -16(3)^2 + 96(3) + 3
y = 147*

If they give you 122 feet and you need to find the time, then just plug that as y and solve for t.
122 = -16t^2 + 96t + 3
0 = -16t^2 + 96t - 119
t = 17/4, 7/4*

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years. Using the empirical rule, approximately what percent of the trees are between 20 and 30 years old? 32%

68%

95%

99.7%

The correct option is 2.

Step-by-step explanation:

Given information: The population mean is μ=25 and standard deviation is σ=5.

We need to find the percent of the trees that are between 20 and 30 years old.

Subtract 25 from each side.

Divide each side by 5.

Using standard normal table we get

68% of the trees are between 20 and 30 years old.

Therefore the correct option is 2.

68%

Step-by-step explanation:

The mean is 25 and the standard deviation is 5.  So 20 is one standard deviation below the mean and 30 is one standard deviation above the mean.

According to the Empirical Rule, 68% of the normal curve is between ±1 standard deviations.  So the answer is 68%.

Jill went out to dinner and left a 15% tip. The cost of the bill is represented by b . The total amount Jill paid is represented as b+0.15b= b, which means that an increase of 15% is the same as

Jill went for dinner

Let the total cost of the dinner = b

He gave 15% tip, then 15%(b) =0.15b

Total cost of the bill = b+0.15b = 1.15b = b

Percentage increase =

= 15%

The cost of the dinner is increased by 15% as he gave the bill.

Therefore, increase of 15% is the same as the percentage of bill.

The length of a rectangle is 6 centimeters more than its width. The area is 216 square centimeters. What are the dimensions?

The length of the rectangle is 18 cm and the width is 12cm.

What is the area of the rectangle?

The space occupied by any two-dimensional figure in a plane is called the area. The two-dimensional space occupied by the rectangle is called the area of the rectangle.

Given that the length of a rectangle is 6 centimeters more than its width. The area is 216 square centimeters.

The area of the rectangle is calculated by the formula:-

Area = length x width

Area = L x W

L = w + 6

Area = ( w + 6 ) w

Area = w² + 6w

216 =  w² + 6w

w² + 6w -216 = 0

w² + 18w -12w -216 = 0

w ( w + 18 ) - 12( w + 18 ) = 0

( w + 18 ) ( w - 12 ) = 0

w = 12

Neglect the negative value.

The length will be calculated as:-

L = w + 6

L = 12 + 6 = 18

Therefore, the length of the rectangle is 18 cm and the width is 12cm.
