Order of operations simplify 22 + 2 to the 3rd power - 36 ÷ 2×3

1 answer:

6 0

Well order of operations is parenthesis but we have none then exponents so :
22 + 8 - 36 ÷ 2 x 3

next is multiplication and division. since there is more.than one we go left to right with the ones we have so:
22 + 8 - 18 x 3
22 + 8 - 54

Now we do addition and subtraction and go left to right since more.than 1
30 - 54
-24 is the answer

Consider the following formula used to estimate height, h, of a seedling after w weeks since planting:

svp [43]

Answer:

Option B. $w=5h-8$

Step-by-step explanation:

we have

$h=(\frac{1}{5})w+(\frac{8}{5})$

Solve for w

That means ----> isolate the variable w

Multiply by 5 both sides to remove the fraction

$5h=w+8$

subtract 8 both sides

$5h-8=w+8-8$

$5h-8=w$

Rewrite

$w=5h-8$

Carol makes a scale drawing of her school using a scale of 8cm:12m. If the length of the playground on the scale drawing is 12.4

mojhsa [17]

A scale of 8cm:12cm would be a scale of 2/3. since this is the case, we can divide the scale drawing of the playground by the scale factor to get the length of the actual playground

12.4/0.6666 = 18.6

The answer is 18.6

Answer:

A. 18

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

A = 1/2(b1 +b2)h

Here, the parallel bases have lengths 3 and 9. The height is 3, so the area is ...

A = 1/2(3 +9)(3) = 18

The area of the trapezoid is 18 square units.
