The answer to A. is 108cm or 1.08m

First convert 2m to cm:
2m x 100 = 200 cm
Next convert 6m to cm:
6m x 100 = 600 cm
Divide the height of the person by his/her shadow:
200cm ÷ 600cm = <span>0.33333333333 = .3</span>
Multiply 360cm by .3:
360cm x .3 = 108cm
108cm ÷ 100 = 1.08m

The answer to B. is 6.8 cm.

The scale seems a bit small... are you sure you don't mean 0.8 m?
a = length of actual car.
8.5 x 0.8 = 1 x a
6.8 = 1 x a
6.8 ÷ 1 = a
6.8 = a

If you did mean 0.8 m... the answer is 680 cm or 6.8 m.

a = length of actual car.
0.8m x 100 = 80cm
8.5 x 80 = 1 x a
680 = 1 x a
680 ÷ 1 = a
680 = a
680 ÷ 100 = 6.8

In a certain Algebra 2 class of 28 students, 14 of them play basketball and 19 of them
erastova [34]

Answer:

13/28

Step-by-step explanation:

Total number of students = 28

Number of students that play basketball = 14

Number of students that play baseball = 19

Number that play neither sport = 5

Number of students playing sports = 28 – 5 = 23

Number of students playing both basketball and baseball = 14 + 19 – 23 = 10

Number of students that play only basketball = 14 – 10 = 4

Number of students that play only baseball = 19 – 10 = 9

Number of students playing basketball or baseball = 4 + 9 = 13

P(a student chosen at random plays basketball or baseball) = 13/28

Find all the zeros of the polynomial function. x^3 + 2x^2 -5x-6 f(x) a) (-3) b) (-2, 1, 3 c) (-3, -1, 2) d) -1) e) none
Flauer [41]

Answer:1,2,3

Step-by-step explanation:

F(x)=x^{3}+2x^2-5x-6=0

disintegrating 2x^2 to x^2 + x^2

x^{3}+x^2+x^2-5x-6=0

x^2\left ( x+1\right )+x^2-5x-6=0

x^2\left ( x+1\right )+x^2-6x+x-6=0

x^2\left ( x+1\right )+\left (x-6 \right )\left ( x+1\right )=0

\left ( x+1\right )\left ( x^2+x-6\right )=0

\left ( x+1\right )\left ( x^2+3x-2x-6\right )=0

\left ( x+1\right )\left ( x+3\right )\left ( x-2\right )=0

A rectangle has an area of 20 square units. What can be said of its height and width? Check all that apply.
Dovator [93]

Answer:

The area of the rectangle is defined as

Area = height* width

Area = 20 u^2  

This means that any multiplication between two numbers which results in the value 20, can be the either the width or the height.

For example, suppose the width and the height are integers.

The possible combination for the pair of values are

1 & 20

2 & 10

4 & 5

With either number being the height or the width
