(76  - 450) - 2

calculate the difference

( - 374) - 2

Remove unnecessary parentheses

- 374 - 2

Calculate the difference

Answer:

x = 7.4 ft.

Step-by-step explanation:

Find the area of the base (32.5ft^2) and divide the area by that to find the height (240.5/32.5= 7.4ft)

The height of the prism is 7.4 feet.

Volume of a three dimensional shape is the space occupied by the shape.

Given is a right trapezoidal prism.

Area of the prism = Base area × Height of the prism

Base is trapezoid.

Base area = [tex]\frac{1}{2}[/tex] (8 + 5) 5

                 = 32.5 feet²

Height of the prism = Length between the bases = x feet

So we have,

32.5 x = 240.5

x = 240.5 / 32.5

x = 7.4 feet

Hence the height of the prism is 7.4 feet.

Hey there!

ORIGINAL EQUATION:

1/2y + 1 = 2

SUBTRACT 1 to BOTH SIDES:

1/2y + 1 - 1 = 2 - 1

CANCEL OUT: 1 - 1 because it give you 0

KEEP: 2 - 1 because it help solve for the y-value

NEW EQUATION: 1/2y = 2 - 1

SIMPLIFY IT!
1/2y = 1

MULTIPLY 2 to BOTH SIDES

1/2y * 2 = 1 * 2

CANCEL out: 1/2 * 2 because it give you 1

KEEP: 1 * 2 because it give you the y-value

NEW EQUATION: y = 2 * 1

SIMPLIFY IT!
y = 2

Therefore, your answer is: y = 2

Good luck on your assignment & enjoy your day!

Answer:

1/2y + 1 = 2

1/2y + 1 - 1 = 2 - 1

1 - 1 is equal to 0

2 - 1 help to solve you the y-value

1/2y = 2 - 1

1/2y = 1

1/2y * 2 = 1 * 2

1/2 * 2 it will give you 1

1 * 2 It will give the y-value

y = 2 * 1

y = 2

The answer is

y = 2

Hey there!

Answer:

LCM = 72

Solution by Division Method

Write your numbers in the top row.

Divide your numbers by prime numbers as long as at least one of your numbers is evenly divisible by a prime number.

Division Table

2 |8|9

2 |4|9

2 |2|9

3. |1 |9

3 |1|3

| 1 |1

Bring down any numbers that are not evenly divisible by the prime number.

When the last row of results is all 1's you are done.

Find the product of the prime numbers in the first column to get the LCM:

LCM = 2 x 2 x 2 x 3 x 3

LCM = 72

Therefore,

LCM(8, 9) = 72

Answer:

90 MPH

30 / (1/3) = 90

Answer:

90mph

Step-by-step explanation;

if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90

in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi

30+30+30=90

or you could do 30* the denominator (in this case its 3), so 30*3=90

Answer:

168 degrees

Step-by-step explanation: first you would do (2x-3)+8x so you would have 10x-3 and that equals 180 degrees since its a straight angle. so you would do 10x-3=180 divide by 10, x-3=18 and add 3 so x=21  then since 2 is 8x you would multiply 8 by 21 which is 168.
