The ratio of the width to the length of a flower is 10:19. How long is the flower bed if it’s width is 6 feet?

1 answer:

6 0

Just set up an equation comparing the two ratios and solve for the length, in this case x.

(10/19)=(6/x)
19/10=x/6
114/10=x

Answer= 11.4 feet for the length of the flower

Answer:

In between 4 and 6

Step-by-step explanation:

Since there are 2 negative signs it automatically goes to positive so u would go to positive 5, which is in-between 4 and 6!

Hope this helps!! :D

What percent of 30 is 240? My answer is 12.5. Can anyone check and see if thats right? :)

Elden [556K]

To find the percentage, we simply do:
240 / 30 x 100
= 800%
The statement says what percent OF 30 IS 240, not what percent OF 240 is 30. Because you divided 30 by 240 and multiplied by 100, you got 12.5%. It is actually 800%

Use the given cost table for the same product from two different companies to create a linear system.

viktelen [127]

40 garments need to be dry cleaned for the two companies to have the same cost.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let f(x) represent the cost for dry cleaning at Company 1. Hence using the points:

(5, 115.25) and (15, 155.75)

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\
 \\
y-115.25=\frac{155.75-115.25}{15-5}(x-5)\\
 \\
y=4.05x+95$

Let g(x) represent the cost for dry cleaning at Company 2. Hence using the points:

(5, 45.25) and (15, 105.75)

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\
 \\
y-45.25=\frac{105.75-45.25}{15-5}(x-5)\\
 \\
y=6.05x+15$

For the cost to be the same:

4.05x + 95= 6.05x + 15

x = 40

40 garments need to be dry cleaned for the two companies to have the same cost.

Are the two functions parallel, perpendicular, the same equation, or none of these choices? -x-3y= -18 9x-3y= -27

Dahasolnce [82]

They are perpendicular. If you normalize both functions into y=ax + b form, you get:

-x-3y=-18 => -3y = -18+x => y= 6 - 1/3 x
9x-3y=-27 -> -3y = -27-9x => y= 9 + 3 x

Just comparing the slopes, you see they are -1/3 and 3, which are each other's negative reciprokes. Negative reciprocal slopes are perpendicular.

Interpret the following exponential function:

exis [7]

Decay factor is 0.77 ; y-intercept is 9 ⇒ answer a

Step-by-step explanation:

The form of the exponential function is $y=a(b)^{x}$ , where

a is the y-intercept (at x = 0)
b is the growth/decay factor
If b > 1, then it is a growth factor
If 0 < b < 1, then it is a decay factor

∵ $y=9(0.77)^{x}$

- To find the y-intercept put x = 0

∴ $y=9(0.77)^{0}$

∵ $(0.77)^{0}=1$

∴ y = 9(1) = 9

∴ The y-intercept is 9

∵ $y=9(0.77)^{x}$

∵ $y=a(b)^{x}$

∵ b = 0.77

∵ 0 < 0.77 < 1

∴ 0 < b < 1

∴ The decay factor = 0.77

Decay factor is 0.77 ; y-intercept is 9
