Think of PEMDAS. PEMDAS is Parenthesis, Exponets, Multiplication, Division, Add, and Subtract. We don't have any Parenthesis, we don't have any Exponets, we do have multiplication: 34•8. I think it's A. 34•8

Answer:

8 cm

Step-by-step explanation:

(See the image attached for details)

The blue segment measures 15 cm
The green segment measures 7 cm
The green and yellow segment when added form the blue segment
So: ? + 7 = 15

Solve:

? + 7 = 15

Subtract 7 on both sides:

? + 7 = 15

-7 -7

? = 8 cm

Therefore, the yellow segment, or the missing side length, measures 8 cm.

krek1111 [17]

First, convert 1/20 to decimal form:
1/20 = 0.05
This means that the sales tax rate is 5%.
Multiply the cost of the item times 0.05 to get the amount of the sales tax:
25.60 * 0.05 = $1.28 sales tax
