Step-by-step explanation:
Answer:

Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x----> corresponding side of the larger trapezoid
y----> corresponding side of the smaller trapezoid

we have


substitute

step 2
Find the area of the larger trapezoid
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x----> area of the larger trapezoid
y----> area of the smaller trapezoid

we have


substitute



As i was taught you would use the Pythagorean Theorem, A^2+B^2=c^2 or (AxA)+(BxB)=(CxC)
so if the ladder is 20ft tall the hypotenuse would be 20ft. Now if the ladder is place 5ft from the way the shortest side adjacent to the 90 degree angle would be 5ft
therefore,
20^2=b^2+5^2
400= B^2+25
(400-25)=B^2+(25-25)
375=b^2
The ladder will reach 19.36ft
First, you want to know the amount of ounces per pound. 1 pound has 16 ounces, so 2 pounds will have 32. Then, you want to take the amount of money you have and divide that by the number of ounces to get the 1 ounce cost. ( 13.98 divided by 32 = 0.4368 ) Finally, you want to multiply that 1 ounce number by 5, and you will get 2.184 or $2.18. ( or you can round up to $2.19 )
