Answer:

About 12 gallons

Step-by-step explanation:

Without bases, find the area of each side of each shape then multiply by four (there are four sides) and add them together

Top shape

find the area of one triangle and the multiply by four

1/2·b·h

1/2·11·15=82.5

82.5·4=330ft²

Bottom shape

find the area of one rectangle and the multiply by four

l·w

15·44=660ft²

660ft²·4=2,640ft²

Add them up

2,970ft²

To find the approximate amount, dived by the number of square ft a gallon can cover

2,970ft²/259ft²=11.467...it goes on

round up to 12

Please help on one math question

kipiarov [429]

Hello from MrBillDoesMath!

Answer:

225

Discussion:

Sum ( 2n - 1) from n = 1 to 15

= Sum(2n) - Sum(1) from n = 1 to 15

= 2 Sum(n) - Sum(1) from n = 1 to 15

= 2* 15(15+1)/2 - (1 + 1 + .. + 1)

The first value comes from the fact that the sum of the first n integers is n(n+1)/2. The latter value sums 15 1's.

= 2 * 15 * 16/2 - 15 => 2/2 = 1

= 15*16 - 15 => 15*16 = 240

= 240 - 15

= 225

Thank you,

MrB

Answer:

The formula for the area of the triangle is:

$\displaystyle A=24x^2$

When x = 3, the area is 216 square centimeters.

When x = 2.4, the area is 138.24 square centimeters.

And when x = 5, the hypotenuse of the triangle is 50 centimeters.

Step-by-step explanation:

We are given a right triangle with a height of 8x and a base of 6x.

The area of a triangle is given by the formula:

$\displaystyle A=\frac{1}{2}bh$

So, by substitution:

$\displaystyle A=\frac{1}{2}(8x)(6x)=24x^2$

When x = 3, the area will be:

$\displaystyle A(3)=24(3)^2=216\text{ cm}^2$

And when x = 2.4, the area will be:

$A(2.4)=24(2.4)^2=138.24\text{ cm}^2$

When x = 5, the height will be 8(5) = 40 cm and the base will be 6(5) = 30 cm.

By the Pythagorean Theorem:

$a^2+b^2=c^2$

So:

$(40)^2+(30)^2=c^2$

The hypotenuse will be:

$c=\sqrt{1600+900}=\sqrt{2500}=50\text{ cm}$

A rectangular sheet of metal has an area of 112 square inches. Its perimeter is 44 inches. What are the dimensions of the sheet?

sveticcg [70]

A) w * L = 112
B) 2w + 2L = 44
A) w = 112 / L then substituting this into B)
B) 2 * (112/L) + 2L = 44
B) 224 / L + 2L = 44
B) 224 + 2L^2 = 44L
B) 2L^2 -44L +224 = 0
L = 14
L = 8

Double Check
Width = 14 Length = 8
2*14= 28 2*8 = 16
28 + 16 = 44

14*8= 112
Correct!!!
