Answer:
3 1/3 miles
Step-by-step explanation:
Find the unit rate. 2 1/2 is the numerator because distance is usually the numerator when it comes to unit rates. 3/4 is the denominator.
F(x) = 3x + 11
Is the function used to show this.
when you know this, you are able to do the following:
f(10) = 30 + 11 = $41
That would be the allowance of the 10th week.
The question, however wants the total.
This again, can be done like this:
f(1) + f(2) + f(3) + f(4) + f(5) + f(6) + f(7) + f(8) + f(9) + f(10) = $275 :)
14 + 17 + 20 + 23 + 26 + 29 + 32 + 35 + 38 + 41 = $275
Sure there is a better formula, but i couldnt seem to make it, sorry.
HUGE UPDATE: The sum is $275 not 200..
1 and 3 are correct answers
A^2+b^2= c^2
48^2+b^2= 80^2
2304+b^2= 6400
Subtract 2304 from both sides.
b^2= 4096
Find the square root.
b= 64
I hope this helps!

Answer:
12
Step-by-step explanation:
First, find the total number of vehicles sold.
15 SUVs were sold, and 80 others were sold
15+80
95
So, 95 vehicles were sold in total.
Now we can make a proportion
15 out of 95 vehicles were SUVs, and we can expect x out of 76 vehicles to be SUVs
15/95=x/76
Cross multiply
95*x=15*76
95x=1140
To solve for x, we need to get x by itself. Since x is being multiplied by 95, divide both sides by 95. This will cancel out the 95, and leave x isolated.
95x/95=1140/95
x=12
So, 12 out 76 vehicles should be SUVs
