Answer:

There were 25 pizzas made last week.

Step-by-step explanation:

It is given that 64% of the pizzas had extra cheese and 16 pizzas had extra cheese. So it means that 64% is equals to 16 pizzas. In order to find how many pizzas were made, you have to find the remaining percentage of pizzas without extra cheese by subtracting 64% from 100% :

100 - 64 = 36 % of pizzas without extra cheese

64 % = 16 pizzas

1 % = 1/4 pizza

36 % = 9 pizzas

We have found out that 9 pizzas were made without extra cheese. The total pizzas were made last week is 25 pizzas (including extra cheese and no extra cheese) :

Total = Extra Cheese + No extra cheese

= 16 + 9

= 25 pizzas

The area of the circle is found by substitifying the radius into the formula A = πr². In this case, with a given radius of 6.5 cm and π as 3.142, the calculated area is approximately 132.732 square centimeters.

To find the area of a circle, you use the formula A = πr², where A represents the area, π is a mathematical constant whose value is given as 3.142 in this case, and r is the radius of the circle.

Since the radius (r) is not directly mentioned in the question, we should understand that the given 13 cm refers to the diameter of the circle, hence the radius will be half, i.e., 13/2 = 6.5 cm.

Substituting these values into the formula gives: A = 3.142 * (6.5)². When you perform the calculation, the result would be about 132.732 square centimeters.

Answer:

x=√-16

Step-by-step explanation:

Since x^2+16=0

Substrate 16

X^2=-16

Square root of both sides

X=√-16

So therefore the final answer is

X=√-16

Answer:

lateral surface area means surface area of vertical walls.

there are 3 vertical walls and each is a rectangle.

hence

lateral surface area = 3 × area of one wall

= 3× ( 8×5 )

= 3 × 40

= 120 square units

Answer:

answer is a

Step-by-step explanation:

the volume is everything on the inside of the tank

surface area would only be the amount of water it take of cover one side

area would just be the size of the glass on bottom

the perimeter would just be the length of all four edges of each side of the fish tank

For the maximum amount of water it takes to fill a rectangular fish tank, we need to know the volume of the fish tank.

Option A is the correct answer.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

The volume of any container gives us the maximum amount the container can hold.

Now,

For the maximum amount of water it takes to fill a rectangular fish tank, we need to know the volume of the fish tank.

Thus,

The volume of the fish tank gives us the maximum amount it can hold.

Answer:

A

Step-by-step explanation:

Lateral surface area = surface area - bases

2(8(11) + 8(5)) =

The bases have areas of 11*5 = 55

Multiply that by 2 and add to 256

256 + 110=

Answer:

106.81 cm or 107 cm.

Step-by-step explanation:

The formula for finding the circumference (perimeter) of a circle is 2 times pi times r or the radius of the circle, or you can find the diameter by multiplying the radius by 2, in this case 34 and multiply that by pi. The diameter is 34 so multiply that by pi and you get 106.81 cm as an approximate. Hope this helps!

The circumferences of the circle is 106.76 cm.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre.

Given that, a circle has radius = 17 cm

We know that, circumference = π × diameter

diameter = 2 × radius = 17 × 2 = 34

circumference = 34 × 3.14 = 106.76 cm

Hence, the circumference of the circle is 106.76 cm

Answer: 9ft² and 12.25ft²

Step-by-step explanation:

The range of the possible areas will be 9 square feet and 12.25 square feet. Then the correct option is B.

Coordinate geometry is the study of geometry using the points in space.

On a coordinate plane, the x-axis is labeled Side length and the y-axis is labeled Perimeter or area.

A line representing the perimeter goes through points (0, 0), (1, 4), (2, 8), (3, 12).

Then the equation of line will be

y = [(12 – 8) / (3 – 2)]x

y = 4x

A curved line representing the area goes through points (0, 0), (2, 4), (3, 9), and (4, 16).

y = x²

Andrew wants to build a square garden, and needs to determine how much area he has for planting.

The perimeter of the garden is between 12 and 14 feet.

Then the value of the side length corresponding to 12 and 14 will be

For y = 12, we have

12 = 4x

 x = 3

Then the area will be

y = 3²

y = 9 square feet

For y = 14, we have

14= 4x

 x = 3.5

Then the area will be

y = 3.5²

y = 12.25 square feet

Then the range of the possible areas will be 9 square feet and 12.25 square feet.

Then the correct option is B.

Answer:

t = 10n + 25

Step-by-step explanation:

At the end of n weeks, the total amount that Melissa would have can be found by the function, t = 25 + 10n.

Melissa made $25 from washing her mother's car and keeps it aside.

She then makes $10 every week. This means that in n number of weeks, the amount she would have made from chores is:

= Amount per week x number of weeks

= 10 x n

= 10n

The total she would then have in n weeks is:

= Amount saved from mother + Amount earned from chores in n weeks

= 25 + 10n

This total is t, so the total function is t = 25 + 10n.

Answer: D) 1/14

Work Shown:

There is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7. Let A = 1/7 which we'll use later.

The probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total. Let B = 1/2

Multiply A and B

A*B = (1/7)*(1/2) = (1*1)/(7*2) = 1/14

This represents the probability of getting an orange marble and flipping tails.

We are able to multiply the probabilities because the two events (picking a marble and flipping a coin) are independent.

Step-by-step explanation:

To find the slope given two points

m = (y2-y1)/(x2-x1)

   = (-1 -3)/(-3 -2)
