Answer:
c. 25.12
this can just be estimated- 8 x pi- or, to make it easy just do 8 x 3= 24. that gets you in the ballpark, and the only answer close is C
Answer:
B. There is one boy for every 6 girls in class.
Step-by-step explanation:
When you have a ratio, it compares two numbers. When you have a ratio 1:6 the colon (:) there can be read as "is to" or "for every".
That means that ratio can be read as 1 is to 6 or "there is 1 for every 6."
In this case 1:6 represents the number of boys to the number of girls to class. This means that there is 1 boy for every 6 girls in class.
Answer:
$4.72 per month
Step-by-step explanation:
The true interest rate is how much more he has to give with interest.
Let's find the interest on $48 first.
Let's convert 18% to decimal, that is:
18/100 = 0.18
Now, to find 18% of $48, we multiply, so,
Interest = $48 * 0.18 = $8.64
In total, he has to pay:
48 + 8.64 = $56.64
This is spread over 12 months (since he has to pay in 1 year), so each month payment would be:
56.64/12 = $4.72 per month
Answer:
9x² + 12
Step-by-step explanation:
Area = Length × Width
Area = 3 × (3x² + 4)
Area = 9x² + 12
y = 45
multiply both sides by 5 to eliminate the fraction
90 = 2y ( divide both sides by 2 )
45 = y
