Answer:
We know that the equation for the speed is:
Speed = Distance/time.
First, we know that he walks 2 miles in 15 minutes.
distance = 2miles
time = 15 minutes
Then his speed in that interval is:
Speed = (2 mi)/(15 min) = (2/15) miles per minute.
Now, at this same speed, he wants to walk 3 more miles. And we want to find the equation that represents how much time she needs to walk 5 miles (the 2 first miles plus the other 3 miles)
We use again the equation:
Speed = Distance/Time
But we isolate Time, to get:
Time = Distance/Speed
Where:
Distance = 5 miles
Speed = (2/15) miles per min
Time = (5 miles)/((2/15) miles per min) = 37.5 minutes
She needs 37.5 minutes to walk the 5 miles.
Answer:
Step-by-step explanation:
x(7x^2+4x) can be expanded by multiplying each of the two terms inside the parentheses by x:
x(7x^2+4x) = 7x^3 + 4x^2
The answer is c because it’s asking for less than so it goes left and the dot isn’t filled so it means less than
1. Find area of hexagon
Number of sides(area of triangle)
(6)1/2(11)(9.5)=313.5
Multiply by 2 since there are two hexagons
=627
2. Find area of the 6 rectangles
Number of sides(area of rectangle)
(6)(11)(20)=1320
3. Add area of both hexagons and the rectangles
627 + 1320= 1947
Therefore, the surface area of this prism is 1947
