Answer:

s = 18 cm

Step-by-step explanation:

Given

V = s³ ( s is the measure of the side )

Here V = 5832, then

s³ = 5832 ( take the cube root of both sides )

$\sqrt[3]{s^3}$ = $\sqrt[3]{5832}$

s = 18 cm

The perimeter of a child’s rectangular sandbox is 18 feet . if the length of the sandbox is one foot longer than the width , wha

Andrew [12]

Answer:

2(b+1+b)= 18

Step-by-step explanation:

Perimeter of a rectangle= 2(l+b)

18 feet= 2(l+b)

length: l, breadth: b

Because the length of the sandbox is 1 foot longer, it will be:

b+1 = l

Substitute l with b+1

2(b+1+b)= 18

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*

Veronika [31]

Answer:

The area of the triangle DEF is 10.

Step-by-step explanation:

Area of a Triangle:

A triangle of base B and height H (both must be perpendicular) has an area of:

$\displaystyle A=\frac{BH}{2}$

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

$\displaystyle A=\frac{5*4}{2}=10$

The area of the triangle DEF is 10.

Svetradugi [14.3K]

Question:

The diameter of a construction pipe is 7ft. If the pipe is 35ft long, what is the volume. (Use 3.14 for pie and round your answer to the nearest cubic foot.)

Answer: V=pir^2h V=3.14*3.5^2*35 V=1346 cu ft

Not fully sure....

But it should be right...
