a rectangle has a side length 2x+9 and side width x. If the perimeter is 36 cm, what is the value of x?
alukav5142 [94]
2(2x + 9) + 2(x) = 36

4x + 18 + 2x = 36

Combine like terms.

6x + 18 = 36

Subtract 18 from both sides.

6x = 18

Divide 6 on both sides.

x = 3

Hope this helps!

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple pa
ValentinkaMS [17]

The two highlighted rows show that for the same amount of blue, Purple #1 uses <u>more</u> red than Purple #2.

This means that Purple #1 is <u>a redder</u> shade of purple than Purple #2.

Purple #2 is <u>a bluer</u> shade of purple than Purple #1.

Step-by-step explanation:

The two highlighted rows show that for the same amount of blue, Purple #1 uses <u>more</u> red than Purple #2.

Making blue's quantity as 3 parts for purple #1 implies red part becomes 1.5 to maintain the ratio 1:2

Purple #1 has 1/3 parts red and 2/3 parts blue. Purple #2 has 1/4th part red and 3/4th part blue.

Hence, Purple #1 is <u>a redder</u> shade of purple than Purple #2.

From the above explanation, <u>Purple #2</u> is a bluer shade of purple than Purple #1.

a woman spent two thirds of her money. she lost two thirds of the remiander and then had $4(aus money) left. how much money did
Dima020 [189]

Answer:

<h3>2/3 lost is 1/3 kept</h3>

<h3>2/3 of the 1/3 kept is 2/9 lost</h3>

  • 1/3 x - 2/9 x = 4

  • 3/9 x - 2/9 x = 4

  • 1/9 x = 4

  • x = 36

<h3>First she lost 2/3 of 36, which is 24. She had 12 left. Then she lost 2/3 of 12 which is 8. She had 4 left.</h3>

  • Hence she started with $36 .

A Ski resort tracks the proportion of seasonal employees who are rehired each season. Rehiring a seasonal employee is beneficial
DaniilM [7]

The test statistic z will be equal to -0.946 and it shows that there is no significant difference in the proportion of rehires between full time and part time.

Given sample sizes of 833 and 386 and result of samples 434 and 189.

n_{1} =833,     n_{2}=386

Proportion  of full time=434/833=0.52

Proportion of part time=189/386=0.49.

Difference in proportion =0.52-0.49

H_{0}:TTF- i∈ rho=0

H_{1}: TTF+i∈ rho≠0.

Mean of difference=0.03

Z=(X-μ)/σ

σ=\sqrt{0.4517/447}

=0.0317

σ=0.0317

z=(0-0.03)/0.0317

=-0.03/0.0317

=-0.317

p value will be =0.1736.

Because p value is greater than 0.01 so we will accept the null hypothesis which shows that there is no significant difference in the proportions.

Hence there is no significant difference in the proportion of rehires between full time and part time.
