A. "hope this helps"
Step-by-step explanation:
Answer:
A) Vol_10_cubes = 2*(5^4) inch^3
B) Area_10_cubes = (2^2)*3*(5^3) inch^2
Step-by-step explanation:
A)The volume of a cube, as all sides are equal:
Vol_cube = (side)^3
side = 5 inches
Vol_cube = 5^3 inch^3
Since we have 10 cubes
10 = 2*5
Vol_10_cubes = 2*(5^4) inch^3
B) A cube has six faces, each with area equal to its squared side
Area_cube = 6*(side)^2
Area_cube = 6*(5)^2 inch^2
Area_10_cubes = 2*5*6*(5)^2 inch^2
Area_10_cubes = (2^2)*3*(5)^3 inch^2
Answer:
b=4
Step-by-step explanation:
So, we have the function 
. We need to find b such that the average rate of change or the slope is -1/8 between the intervel [2, b]. First, let's find f(2).
f(2) = 1/(2) = 1/2
So, we have the point (2, 1/2)
At point b, f(b) = 1/b.
Let's plug this into the slope formula:
Now, we just need to solve for b. First, let's multiply both the numerator and denominator by b (to get rid of the annoying fraction in the numerator).
Now, cross multiply.
Solve for b. Factor using the numbers -4 and -2.
Thus, b=4 or b=2.
However, b=2 is not a possible solution since the interval [2,2] means nothing. Thus, b=4.

Answer:</u></h2>
Jared and Pedro walked a total of <u>4.3 miles</u>
<h2><u>
Step-by-step explanation:</u></h2>
- The equation for distance is <u>speed = distance ÷ time.</u>
- Rearrange the equation to make distance the subject:
<em>(multiply both sides by time)</em>
<em> </em><u>Distance = Speed × Time</u>
- Convert your numbers into suitable units:
1 mile ÷ 15 = <u>0.06m/minute</u>
- Finally, substitute the numbers into the equation and solve:
Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)
