Answer:

Step-by-step explanation:

let y represent number of years...

9 ft tall = (12 * 9) = 108 inches

10 ft tall = (12 * 10) = 120 inches

Type A : 9 ft (or 108 inches) and grows 6 inches per year..

108 + 6y

Type B : 10 ft (or 120 inches) and grows 3 inches per yr

120 + 3y

how many years will it take them to be the same height...so when will they be equal....so set them equal and solve for y

108 + 6y = 120 + 3y

6y - 3y = 120 - 108

3y = 112

y = 112/3

y = 37 1/3 years....or 37 years and 4 months <====

check...

108 + 6(37 1/3) = 120 + 3(37 1/3)

108 + 6(112/3) = 120 + 3(112/3)

108 + 672/3 = 120 + 336/3

672/3 - 336/3 = 120 - 108

336/3 = 112

112 = 112 (correct)

timurjin [86]

Answer: A.Kelvin’s because he surveyed people leaving an area where food is sold


Step-by-step explanation:

Given: Kelvin and Lewie each design surveys in order to determine the number of people who buy food at the mall.

Kelvin surveys every other person leaving the food area.

Thus, he doesn't know about the people who do not buy food at mall whereas Lewie surveys every fifth person leaving the mall’s main entrance.

Thus, by this systematic random sampling he knows out of how many people the number of people buy food at mall.

Hence, Kelvin’s survey is likely to produce less valid results because he surveyed people leaving an area where food is sold.

Which of the following square root of -80
Marta_Voda [28]

You can factor -80 as

-80 = (-1)\cdot 16 \cdot 5

So, we have

\sqrt{-80} = \sqrt{(-1)\cdot 16 \cdot 5}

The square root of a product is the product of the square roots:

\sqrt{-80} = \sqrt{(-1)}\sqrt{16}\sqrt{5}

Since i^2=-1 and 4^2=16, we have

\sqrt{-80} = 4i\sqrt{5}
