what is an area of a trapezoid

Answer:

z=10

Step-by-step explanation:

We know that the ratio 7:21 is equal to the ratio of 10:3z.

Let's model that in proportions:

7               10

-       =        -

21             3z

Now that the equation is in proportional form, we can cross-multiply to find the value of z.

7 * 3z = 21 * 10 - Multiply both sides

21z = 210 - Divide both sides by 21

z=10

The answer is z=10.

The employer contribute to her retirement plan is $2120.

Many American firms provide 401(k) plans, which are retirement savings plans with favourable tax treatment for the saver. It bears a section number from the United States Internal Revenue Code (IRC).

When a worker enrols in a 401(k), they consent to have a portion of each paycheck put directly into an investing account. A portion or the entire contribution may be matched by the employer. The employee has a variety of investing alternatives, most often mutual funds.

Given:

Jayne contributes $5,300

Now, the contribution of $0.40 for each dollar

So, employer contribute to her retirement plan

= 5300 x 0.40

= $2120

Hence, The employer contribute to her retirement plan is $2120.

Answer:

[tex]15\frac{7}{50}[/tex]

Step-by-step explanation:

Given that:

22 people share 333 chocolate bars equally. Each chocolate bar is the same size.

To Find:

About how much chocolate does each person get?

Solve:

Since, it given us that 22 people share 333 chocolate bars equally and how much chocolate does each person gets. Therefore we have to divide the chocolate bars by the number of people.

Answer:

No Solutions

Step-by-step explanation:

First to complete the square, it will need to look something like

a^2+2ab+b^2

so in order to get that we can see that 4n^2+8n seems to be missing a piece.

a is the square root of 4n^2 which is 2n.

8n/2n=4

4/2=2

b=2

so now add 2 to both sides of the equation so now it's

4n^2+8n+4=-13

rewrite as (2n+2)^2=-13

Now you see a negative number as the result of a exponent.

A number squared will never be negative.

Therefore the answer is

No Solutions

Step-by-step explanation:

it needs 4×2 = 8 cubes asking the length, 5×2 = 10 cubes along the width, and 3 1/2 × 2 = 7 cubes along the height.

so, altogether

Most of the time you can go on a website that can cauculate it.

Step-by-step explanation:

How to cauculate the MAD:

Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

Y-INTERCEPT

[tex]y = 5x^2 - 16x + 10[/tex]

The y-intercept is where the equation/curve/parabola cosses the y-axis.

The y-axis is where x = 0. (The x-axis is where y = 0)

To find the y-intercept:

[tex]\text{y-axis} \rightarrow \text{x = 0} \rightarrow y = 5(0)^2 -16(0) + 10 = 10[/tex]

The y-intercept must be at (0, 10)

X-INTERCEPT (ROOTS/SOLUTIONS)

[tex]y = 5x^2 - 16x + 10\\\text{make it equal 0}\\y = 0\\\therefore 5x^2 - 16x + 10 = 0[/tex]

We need to use the quadratic formula

The quadratic formula helps us find what values of [tex]x[/tex] make the equation = 0

Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-(-16) + \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\\x = \frac{16 + \sqrt{256-200}}{10}\\x = \frac{16 + \sqrt{56}}{10}\\x = \frac{16 + 2\sqrt{14}}{10}\\x = \frac{8 + \sqrt{14}}{5}\\\\\\x=\frac{-(-16) - \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\text{doing the same thing...}\\\text{end up with...}\\x = \frac{8 - \sqrt{14}}{5}\\[/tex]

Hi!

Your answer is the 1st one, 36 inches of ribbon.

The question states this is a square picture frame. That means that all the side lengths are the same.

We are given a side length of 6 inches.

In order to find the area of a square, we multiply the length and the width together.

In this problem, the sides of the picture frame measure 6 inches. Therefore:

[tex]6*6=36[/tex]

Answer:

See below

Step-by-step explanation:

100 ft in 4 min     =   25 ft/min

125 feet in 5 min =   25 ft min

so the height is   d = 25 * m           d = height   m = minutes

25* 8 = 200 feet

So, the prime factorization of 567 can be written as 34 × 71 where 3, 7 are prime.

From the first figure, write all the values where dark point is drawn

53, 62, 80, 86, 89  

        The upper extreme is the highest value, which is 89.

        The upper quartile is 86 and the lower quartile is 62.
