Sebastian is curious to know how tall the announcer's box is on his school's football field. On a sunny day he measures the shadow of the box to be 45 ft and his own shadow is 9 ft. Sebastian is 5 ft 10 in tall. Find the height of the box.

Step-by-step explanation:

Given:

So we have the proportion:

Notice that our measurements are not all in the same units. Change both numerators to inches and then we can cross multiply.

<=>

<=> 79(45) = 108x

<=> x ≈ 32.9 ft

So the height of the box is 32.9 ft

b

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
