Answer:
The answer is C= 109.96 cm
Step-by-step explanation: Since it's a diameter, you'll have to split it in half to find the radius, from there, you can use the normal formula.
A quadrilateral is a polygon. [always]
First I added 2.5+4.25=6.75
Then do $54/6.75=$8
Answer=$8
The variable a could be
5/2 or 1/2
Hope I could help :)
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
