First you have to find what 30% of ten is, and then add it to the 10. So how do you find 30 % of 10? In math...
"of" means ×
"is" means =
30% of 10 is
30 % × 10 =
change 30% to a decimal by dividing by 100 ( move the decimal to the left 2 places)
.30 × 10 = 3
So 30% of ten is 3. Now since we are increasing by 30%, we have to add it to the original value, 10.
3 + 10 = 13
So 10 millimeters increased by 30% is
13 millimeters
Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2
Answer:
$12.27
Step-by-step explanation:
.07 times 179.53 is 12.5671 so rounded to 12.27
If you add the two numbers, 10 +8 is 18. The fractional parts are 1/4 and 2/4 which equals 3/4. So the total length is 18 and 3/4 feet.
