Answer:
73 mph
Step-by-step explanation:
The question seems to be incomplete because the model is missing, I found a similar question with the addition of the model, so if we can solve it (see attached image).
We have that the model would be:
y = 43.81 - 0.395 * x
We need to solve for x, if y = 15
Replacing:
15 = 43.81 - 0.395 * x
Solving for x we have:
0.395 * x = 43.81 - 15
0.395 * x = 28.81
x = 28.81 / 0.395
x = 72.9
We are asked to round to the nearest number therefore x = 73.
The car will average 15 miles per gallon at the speed of 73 miles per hour.
Answer:
2
Step-by-step explanation:
15 - 3 = 12 / 6 = 2
Answer:
tge area of triangle is 36 in2 so she can only create 4 triangle
Step-by-step explanation:
area of square grid = 12 × 12
=144
area of triangle = 1/2 × 6 × 6
;;; = 18 ×2
=36
area if square grid/ area of triangle
=144/ 36
=4
When x=0, y=4...
Therefore:
4=a*b⁰
b⁰=1, so a=4.
----------
When x=1, y=2...
Therefore:
2=4*b¹
4b=2
b=2/4
So... b=1/2.
This means that:
y=4*((1/2)^x)
The new mixture exists 56.5% peanuts.
<h3>How to estimate the total number of peanuts required for the mixture?</h3>
The first batch of 9 lb of mixed nuts possesses 40% peanuts.
This means the quantity of peanuts exists:
9 
40/100 = 3.6 lb
The second batch of 9 lb of mixed nuts possesses 73% peanuts.
This means the quantity of peanuts exists:
9 73/100 = 6.57 lb
The total quantity of peanuts in the mix exists
3.6 lb + 6.57 lb = 10.17 lb
There exist 9 lb + 9 lb = 18 lb of mix.
Therefore, the percent of peanuts in the mix exists:
10.17 / 18 100 = 56.5%
The new mixture exists 56.5% peanuts.
