Answer:

The height of the pyramid is 2.4\ ft

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

V=\frac{1}{3}b^{2}h

we have

V=20\ ft^{3}

b=5\ ft

substitute and solve for h

20=\frac{1}{3}(5)^{2}h

60=(25)h

h=60/(25)=2.4\ ft

PLEASE HELP!!!

If we take the perimeter of the park as being equivalent to the distance that Anwar walks, then we can calculate the number of blocks he walks and then multiply this by the width of each block, thus:

Number of blocks walked = 1 + 2 + 2 + 1 + 1 + 1 = 8
Distance walked = 8*300 = 2400 feet

(You could also draw a diagram to help present this in a visual way but it is not necessary)

Kyla used 550 grams of wool to knit a sweater, a hat, and a scarf. For the hat she used 5 times less wool than the sweater and 5
Brrunno [24]
This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
 therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
