What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent

Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches

QRST is a square. PQ= square root 2 RU= 4 What is the length os SU? Round to the nearest tenth

ahrayia [7]

Answer:

3.5 units

Step-by-step explanation:

Because ΔPQT is 45-45-90, QT = PQ√2. Therefore, QT is 2.

RS is also 2 because all sides of a square are congruent.

Knowing this, we can use the pythagorean theorem to find SU.

RS² + SU² = RU² -> 2² + SU² = 4² -> 4 + SU² = 16 -> SU² = 12

So, SU = √12 ≈ 3.5 units

Market Basket sells chocolate chip cookies . A-Best cookies are 12 cookies for $6.00. A- Okay cookies sell 20 cookies for $ 8.00

agasfer [191]

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

Step-by-step explanation:

The unit cost is obtained by dividing the total cost by the quantity

Given

Best Cookies:

Cost = $6.00

Quantity = 12

So the unit price will be:

$Unit\ price\ for\ best\ cookies = \frac{6}{12}\\=0.5\ dollars\ or\ 50\ cents$

Okay Cookies:

Cost = $8.00

Quantity = 20

The unit price is:

$Unit\ price\ of\ okay\ cookies = \frac{8}{20}\\= 0.4 \dollars\ or\ 40\ cents$

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

If a 51 gal hot water tank holds 425 lb of water, what weight of water will a 64 gal tank hold? (Round to Nearest whole number)

Novay_Z [31]

Answer:

533 lb

Step-by-step explanation:

We expect the weight of 64/51 times the amount of water to be 64/51 times as much as 425 lb:

(64/51)(425 lb) = 533 1/3 lb

The 64 gallon tank will hold about 533 pounds of water.
