Answer:
It'll take 25 hours to get to the auto shop
Step-by-step explanation:
Given
Distance = 5 miles
Speed =1056 feet per hour
Required
How long will it take to the auto shop
This can be solved using Speed's formula;
Substitute values for Speed and Distance
1 mile = 5280 feet;
So:
Cross Multiply
Divide both sides by 1056ft
<em>Hence, it'll take 25 hours to get to the auto shop</em>
Answer:
Perimeter of one triangle is 65 dm
Perimeter of other triangle is 52 dm
Step-by-step explanation:
Please remember the concept
If sides are in the ratio of a:b
Then the area in the ratio of
It is given sum of their perimeter is 117.
Let the small triangle has perimeter as x.
So, perimeter of big triangle is 117-x.
So, we can set up equation as
Cross multiply
50(117-x)^2 =32x^2
Expand the left side
50=
Distribute the left side
684450-11700x+=
Subtract both sides and rewrite it
Solve this quadratic for x.
Divide both sides of the equation by 18 to simplify.
-650 x+38025=0
Now, if possible let's factor
Find two integers whose multiplication is 38025 but adds to -650.
-65 and -585 works.
So, we can rewrite it as
(x -65)(x-585) =0
Solve them using zero product property
x=65, x=585
So, x=65 works here.
So, perimeter of one triangle is 65 dm
Perimeter of other triangle is 117-65= 52 dm
