A. 30 miles
step by step explanation: 14.75-4.25 (one time fee)
14.75-4.25=10.5
10.5 divided by 0.35 is 30
therefore the answer is A, 30 miles
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
15 x .30 = 4.50 discount 15-4.50= 10.50
10.50 x .40 = 4.20
Final cost of shirt 10.50-4.20 = $6.30
Answer: Product of powers

The product of powers rules basically says that two powers, let's call them

and

, with the same base (a) multiplied together equals

.
In your problem you can see that

and

are being multiplied together and the exponents are being added, which is what the "product of powers" law says.
It should be y = 252 sorry if its wrong !
