Answer:
$95.38
Step-by-step explanation:
step 1
Find the area of one button
The area is equal to
we have
---> the radius is half the diameter
Convert to meters
assume
substitute
step 2
Find the area of 1,00 buttons
Multiply by 1,000
step 3
Find the cost
Multiply $15 per square meter by the total area of 1,000 buttons
First we need to find what 3% of 700 is. We know 10% is 70, 5% is 35, so we need to find out what 3% is. If you don't know how to calculate percentages of a number, I recommend starting with 10%. This way you know 10% of the number is 70, so you will also know that 1% of the number is 7. 7 x 3 = 21. So 3% of 700 is 21. Since it was over 6 years, we multiply 21 x 6. That gives us 126. She will be paid $126 in interest in the first six years.
You could put,
19
+ 6
———
25
Then write,
19+6=25
Answer:
D) 6
Step-by-step explanation:
set Q has 16 values which are all even values from 4 to 36
set Z has 11 values that are multiples of 3 from 4 to 36 (6,9,12,15,etc.) however, we have to eliminate the odd ones, leaving the following six:
6, 12, 18, 24, 30, 36
