Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he nee

Alex777 [14]

Answer:

Tristan will need 32 feet of material for the perimeter of the garden.

Step-by-step explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

$Area = A = s^2$

s is for side

Putting the value of area

$64 = a^2$

Taking square root on both sides

$\sqrt{s^2} = \sqrt{64}\\s = 8\ feet$

The length of side is 8 feet.

Perimeter will be:

$P = 4*s\\P = 4*8\\P = 32\ feet$

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.

At 2pm the level of the water in the pool was 10 feet. At 6pm the level of water was 2 feet. Find the constant rate of the water

adelina 88 [10]

Assuming that the pool was drained at a constant rate, the speed at which it was drained can be expressed as a function of time. In this case, the pool level will be expressed in feet per hour.

The time changed by 4 hours (6-2), and the level of the pool changed by -8 feet (2-10). Diving the feet by the hours to get the rate of decreasing depth, we find that the rate equals -2 feet/hour.

15 = -4p + 7<br><br><br> solving equation

Ratling [72]

Answer:

p = -2

Step-by-step explanation:

15 = -4p + 7

4p + 15 = 7

4p + 15 - 15 = 7 - 15

4p = -8

4p/4 = -8/4

p = -2
