Answer:
120 ft
Step-by-step explanation:
The distance the gravel covers is the total distance times the percentage that the gravel covers
We know the gravel covers 66 ft and the percentage is 55%
distance gravel = total distance * percentage
66 = total distance * 55%
66 = total distance *.55
Divide each side by .55
66/.55 = total distance *.55/.55
120 = total distance
Answer:
3 median= 45
4 median=41
Step-by-step explanation:
mean you add the total and you divide by the number of values
mode the most repeated like no.4 is 41
range the highest-the lowest
Answer:
2y+1=0
Step-by-step explanation:
a number one greater than y is y+1
so sum of y and y+1= 2y+1
Answer:
A The sum of the first 11 terms is 88
Step-by-step explanation:
Since -4 - (-7) = -1 - (-4) = 2 - (-1) = 3
Your sequence is an arithmetic sequence with a common difference of 3.
The formula for the sum of an arithmetic sequence is
where 
In your case
, n = 11 and 
We know everything except the eleventh term.
So, we need to find the eleventh term or
=
+ (n - 1)d
= -7 + (11 - 1)3
= -7 + 30 = 23
Now, S = 
The sum of the first 11 terms is 88
Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to

h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...

now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
