A rectangular yard measuring

aliina [53]

The entire yard is 36x54 so you would draw a rectangle with those measurements, since there is a border of 3 you should draw another rectangle in the middle with measurements 6 less than the original. 30x48
since you are finding the area of the walk, you would find the larger area, then subtract the smaller rectangle

(36*54)-(30*48)
1944-1440
504 square feet of walk

two positive integers are 3 units apart on a number line. their product is 180. wich equation can be used to solve for m, the gr

3241004551 [841]

Answer:

m^2-3m-180=0

m=15

Step-by-step explanation:

greater integer = m

small integer = n

we know that m = n+3 or n = m-3

we also know that n*m = 180

replace n for m-3

(m-3)*m=180

m^2-3m-180 = 0

(m-15)(m+12)=0

so m = 15 or -12, but since problem states positive, m=15

If the area of the following parallelogram is 135 square feet, what is the length of the base?

sleet_krkn [62]

Answer:

9ft

Step-by-step explanation:

The area is 135ft and the formula for area is length x width.

on the image it shows the height is 5yds and we want feet since that's that the area is in. a yard = 3 feet so its 3 x 5 = 15.

since the formula to find area is multiplication, use division to find a number in the equation. so

135 divided by 15 = 9.

The length of the base is 9ft.

Volume of a sphere with a diameter of 8 meters? Use 3.14 for pi.

kvasek [131]

Answer: " 267.95 m³ " .
______________________________________________________
Explanation:
________________________________________________________

V = (4/3) * $\pi$ * r³ ;

Given: diameter, "d" = "8 m" ;

radius, "r" = 8 m / 2 = 4 m "

V = (4/3) * $\pi$ * r³

V = (4/3) * $\pi$ *(4m)³

V = (4/3) * (3.14) * 4³ * m³ ;

V = (4/3) * (3.14) * (4*4*4) * m³ ;

V = (4/3) * (3.14) * (64) * m³ ;

V = 267.9466666666666667 m³ ;

round to: " 267.95 m³ " .
