Hello. Can y’all help me on this please :)

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiply both sides by 100.

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Divide both sides by 50.

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

The amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Answer and Step-by-step explanation:

Because of the vertical angles theorem, the angle that is 65 degrees would be equal to y.

y = 65°

X and Y are supplementary angles, which form a linear lair. This linear pair will add up to 180 degrees.

TO find x, we subtract 65 from 180.

180 - 65 = 115

x = 115°

X and Z are vertical angles, so they are equal to each other.

z = 115°

x = 115°

y = 65

z = 115°

To solve for the length of PQ, we would use the Pythagorean theorem equation.

[tex]a^{2} +b^{2}= c^{2} \\\\\\a = PQ\\\\b = QR\\\\c = PR\\\\\\a^{2} + 24^{2} = 25^{2} \\\\a^{2} + 576 = 625\\\\a^{2} = 49\\\\a = 7[/tex]

The length of PQ is 7.

Answer:

y = 65 degrees

x = 115 degrees

z = 115 degrees

Step-by-step explanation:

the angle between c and a will be the same as y because of vertical angles

the same goes for x and z

y and x are supplementary angles, so if y is 65 then you do 180 - 65 to get 115

Answer:

9/11

Step-by-step explanation:

The green gems are red gems divided by three. The red gems are gold gems divided by six. Make the number of gold gems, g. The red gems would be g/6, and the green gems (g/6)/2=g/18. So, the total marbles would be g+g/6+g/18=18g/18+3g/18+g/18=22g/18=11g/9. Now you have to find what percent of 11g/9 is g. (11g/9)(percent)=g. The percent as a fraction is 9/11.

Answer:

348 inches

Step-by-step explanation:

29x12=348

The length of Mr. Shelby's wall is 348 inches.

A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.

Given that, the length of one wall in Mr. Shelby's classroom and 29 feet, we need to convert it into inches.

So,

1 ft = 12 inches

Therefore,

29 ft = 29 × 12

= 348 inches

Hence, the length of Mr. Shelby's wall is 348 inches.

Because x can be anything that's not imaginary and y has to be below 2 always because of the negative value added before the 3. Also it's impossible to reverse the sign of the negative because negative x would only result in 3 becoming a fraction.

The women who see the commercials without celebrities is in the controler group. Correct option is A.

In an experiment, the control group is a group of individuals who do not receive the specific treatment or intervention being studied. The purpose of the control group is to serve as a baseline for comparison, allowing researchers to evaluate the impact of the treatment by comparing it to the group that did not receive the treatment.

In this scenario, the clothing manufacturer is trying to determine whether celebrity endorsements influence a customer's decision to buy its products. To evaluate this influence, they are conducting an experiment with two separate groups of potential buyers:

Group A: Potential buyers (women) who will see a series of commercials without celebrities.

Group B: Potential buyers (men and women) who will view a series of commercials with celebrities.

The control group, in this case, is Group A - the women who see the commercials without celebrities. They do not receive the treatment (celebrity endorsements) being studied. Their responses and behavior will serve as a baseline against which the effects of celebrity endorsements on the buying decision can be compared in Group B.

By comparing the responses and behavior of the two groups, the clothing manufacturer can determine whether celebrity endorsements have a significant influence on the customers' decision to buy their products. The control group is essential for ensuring that any observed effects in Group B are not due to other factors but rather can be attributed to the presence of celebrity endorsements.

Answer:

{9} Slope: -1

Y-intercept = 0

Step-by-step explanation:

Slope-----

Recall slope-intercept form

y=mx+b, with slope m and a y-intercept of b. With this in mind, we can rewrite our equation as y=−x+0

We see that our slope, or coefficient on x, is −1.

Y-intercept-----

We can rewrite this equation as:y=1x+0

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

For this equation:y=1x+0

Therefore:

The slope is m=1

The y-intercept is b=0 or (0,0)

Hi there!

[tex]\large\boxed{\text{ L = 6 ft, w = 5.5 ft}}[/tex]

Use the following equation for the area of a rectangle:

A = l × w

Since the length is 5 ft less than twice the width, we can write an expression for the length in terms of the width:

l = 2w - 5

Plug the given area and expression into the equation:

33 = (2w - 5) × w

Distribute:

33 = 2w² - 5w

Move everything over to one side:

0 = 2w² - 5w - 33

Factor the equation:

0 = (2w - 11)(w + 3)

Find each w value by setting each expression equal to 0:

0 = 2w - 11

11 = 2w

w = 5.5

0 = w + 3

-3 = w

Since dimensions must be positive, the width is 5.5 ft.

Plug this value into the initial equation to solve for length:

33 = 5.5l

33/5.5 = l

l = 6 ft.

The dimensions are length = 6ft, and width = 5.5ft.
