If a square lot has an area of 2025 square feet how many feet long is each side?
A.
81 feet
B.
45 feet
C.
1012.5 ft
D.
50 ft

7 answers

To find the length of each side of a square lot with an area of 2025 square feet, you can use the formula for the area of a square:

\[ \text{Area} = \text{side} \times \text{side} = \text{side}^2 \]

To find the length of each side, take the square root of the area:

\[ \text{side} = \sqrt{2025} \]

Calculating the square root:

\[ \sqrt{2025} = 45 \]

Therefore, each side of the square lot is 45 feet long.

The correct answer is:

B. 45 feet

Jamie filled up her car with 17 gallons of gas and paid $2.79 per gallon. How much did Jamie spend on gas to fill up her car?
A.
$19.79

B.
$22.32

C.
$46.13

D.
$47.43

To find out how much Jamie spent on gas, you can multiply the number of gallons by the price per gallon:

\[ \text{Total Cost} = \text{Number of Gallons} \times \text{Price per Gallon} \]

Given that Jamie filled up with 17 gallons at $2.79 per gallon:

\[ \text{Total Cost} = 17 , \text{gallons} \times 2.79 , \text{dollars/gallon} \]

Calculating that:

\[ \text{Total Cost} = 17 \times 2.79 = 47.43 \]

Therefore, Jamie spent $47.43 to fill up her car.

The correct answer is:

D. $47.43

Billy was standing on a diving board that was 4 feet above the water. He dove into the pool which was 8 feet deep and touched the bottom. Which statement accurately describes this situation?

A.
If 0 represents the height of the diving board, then +4 represents the water level and –8 represents the bottom of the pool.

B.
If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.

C.
If 0 represents the height of the diving board, then 4 represents the water level and 8 represents the bottom of the pool.

D.
If +8 represents the height of the diving board, then 0 represents the water level and –4 represents the bottom of the pool.

Let's analyze the situation:

  • The diving board is 4 feet above the water.
  • The water level is considered 0 feet.
  • The bottom of the pool is 8 feet deep.

Now, if we define the heights:

  • The diving board at +4 feet means it is 4 feet above the water level (0 feet).
  • The water level is at 0 feet.
  • The bottom of the pool is 8 feet below the water level, which can be represented as -8 feet.

Now let's review the statements:

A. If 0 represents the height of the diving board, then +4 represents the water level and –8 represents the bottom of the pool.

  • This is incorrect because it misplaces the zero reference.

B. If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.

  • This is correct. It accurately describes the heights based on the proposed references.

C. If 0 represents the height of the diving board, then 4 represents the water level and 8 represents the bottom of the pool.

  • This is incorrect because it misplaces the zero reference.

D. If +8 represents the height of the diving board, then 0 represents the water level and –4 represents the bottom of the pool.

  • This is incorrect because it misplaces the zero reference.

Thus, the correct statement that accurately describes the situation is:

B. If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.

Multiple Choice Question
Mr. Emery bought 6 pizzas for the math team. The total cost of the order was $58.50. Each pizza cost the same amount. What is the unit cost per pizza for the order?

A.
$0.10

B.
$6.00

C.
$9.75

D.
$58.50

To find the unit cost per pizza, you can divide the total cost of the order by the number of pizzas:

\[ \text{Unit Cost per Pizza} = \frac{\text{Total Cost}}{\text{Number of Pizzas}} \]

In this case:

\[ \text{Unit Cost per Pizza} = \frac{58.50}{6} \]

Calculating that:

\[ \text{Unit Cost per Pizza} = 9.75 \]

Therefore, the unit cost per pizza for the order is $9.75.

The correct answer is:

C. $9.75
