Sergeu [11.5K]3 years ago

4 0

Answer:

400%

Step-by-step explanation:

Divide 6 inches by 1.5:

6/1.5 = 4

6 is four times 1.5

If 1.5 is considered 100%, 4 times 1.5 is 400%

Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then find the value of y when x=12

lidiya [134]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable.

Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes

y = kx

If y = 8 when x = 3, then

8 = 3k

k = 3/8

Therefore, the direct variation equation that relates x and y is

y = 3x/8

When x = 12, then

y = 3 × 12/8

y = 4.5

Simplify (2/9)^3 A.6/9 B.8/729 C.2/720

saw5 [17]

Answer:

$\frac{8}{729}$

Explanation:

Before we begin, remember that:

( $\frac{a}{b}$ )ⁿ = $\frac{a^n}{b^n}$

This means that power is distributed in case of division

The given is:

$(\frac{2}{9} )^3$

Applying the above rule, we would get:

$(\frac{2}{9} )^3$ = $\frac{2^3}{9^3} = \frac{2*2*2}{9*9*9} = \frac{8}{729}$

Hope this helps :)

What is the area of a trapezoid if the base is 5, 17, 5 and height is 4

Genrish500 [490]

Answer:

44 units squared.

Step-by-step explanation:

The formula for area of a trapezoid is:

$a = \frac{ b^{1} + {b}^{2} }{2} h$

a = missing area

b1 = short base (5)

b2 = long base (17)

h = height (4)

(5 + 17) ÷ 2 = 11

11 × 4 = 44

area = 44
