Below are two inequalities and the graphs of their without the shading. By imagining where the shading should be, identify which point would satisfy BOTH
inequalities

Answer:

7

Step-by-step explanation:

4x-7=21

4x=28

x=7.....

The number is 7.

We have a sentence - "The difference of four times a number and seven is 21".

We have to find the number.

The expression representing the above statement is -

n = 40 - 20 = 20

According to the question, we have -

The difference of four times a number and seven is 21.

Assume the number be x.

Therefore -

4x - 7 = 21

4x = 28

x = 7

Hence, the number is 7.

Answer:

.4521

Step-by-step explanation:

when converting a percentage to a decimal you have to move the decimal point over two times to the left. do if you have 100% you moved the decimal point over two and get 1.00

Answer:

0.4521

Step-by-step explanation:

Instead, you can simply multiply a number by 45.21 as a decimal to get the answer.

45.21 percent means 45.21 per hundred. Therefore, to get 45.21 as a decimal, all you have to do is divide 45.21 by 100 like so:

45.21 ÷ 100 = 0.4521

Shortcut: When you divide anything by 100, just move the decimal point two places to the left.

Normally, to calculate 45.21 percent, you would multiply a number by 45.21 percent and then you would take the product of that and divide it by 100 to get the answer.

Answer:

HM > CH

Step-by-step explanation:

You are correct, I didn't see the option HM > CH, which is correct, since the angle 90 degrees is larger than the angle 73, and then the sides opposite to them must follow suit.

Therefore, the correct answer is: HM > CH

The true statement from the triangles is (b) HM > CH

From the question, we have the following parameters that can be used in our computation:

The figures

Next, we have

Angles at corresponding points = 90 degrees and 73 degrees

Since the angle 90 degrees is larger than the angle 73 degrees, and then the sides opposite to them must also have the same relationship

Using the above as a guide, we have the following:

The true statement is (b) HM > CH

Answer:

Step-by-step explanation:

The interest accrued is $258.48.

Step-by-step explanation:

Given that:

Initial balance in the savings account = $359

Interest rate = 8%

Time for which no withdrawals or deposits were done = 9 years

To find:

Simple Interest accrued = ?

Solution:

First of all, let us have a look at the formula for simple interest.

Where P is the Principal Amount.

R is the annual rate of interest

T is the time in years.

Here, we are given:

P = $359

R = 8%

T = 9 years

Let us put all the values in the formula:

So, the interest accrued is $258.48.

Answer:

30xy

Step-by-step explanation:

I divided this shape into a square and a rectangle.

Solve:

First I multiplied 2x and 3y

2x*3y= 6xy

Then I multiplied 6x and 4y

6x*4y= 24xy

Then I added them together

24xy+6xy= 30xy

Answer:

D. y=-1/5(x)

Step-by-step explanation:

To find the equation of a line, use the formula y=mx+b, where x and y represent your x and y coordinates, m is your slope and b is your y-intercept.

b is you y-intercept, this is where the line cuts the y-axis. We can see from the graph that the line cuts the y-axis at (0,0), so c=0.

Now we have y=mx

Sub in one of our points (10,-2):

-2=m10

m=-1/5

So our equation looks like this:

y=-1/5(x)

Step-by-step explanation:

I don't see any of the choices, but I'll just give you what it's equal to. The expression is equal to: sqrt2, which is approximately 1.414.

El área total a pintar será:

[tex]A_{tot}=25.2\: m^{2}[/tex]

Step-by-step explanation:

Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.

El área de un triángulo es:

[tex]A_{t1}=\frac{b*a}{2}[/tex]

b es la longitud de la base (b=3 m)

a es la apotema, osea la altura del triangulo (a = 2.8)

[tex]A_{t1}=\frac{2.8*3}{2}[/tex]

[tex]A_{t1}=4.2\: m^{2}[/tex]

Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

[tex]A_{tot}=25.2\: m^{2}[/tex]

Step-by-step explanation:

Answer:

She scored in the 90th percentile.

90th percentile is better than 90% of the students who took the test, so yes, she will be admitted.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The scores on this test are known to be normally distributed with a mean of 725 and a standard deviation of 115.

This means that [tex]\mu = 725, \sigma = 115[/tex]

She must score better than at least 75% of the students who took the test.

So her z-score should have a pvalue of at least 0.75.

Harriet takes the test and scores 874.5. 1. (2pts) What percentile did Harriet score in?

We have to find the pvalue of Z when X = 874.5.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{874.5 - 725}{115}[/tex]

[tex]Z = 1.3[/tex]

[tex]Z = 1.3[/tex] has a pvalue of 0.9032

She scored in the 90th percentile.

Will Harriet be admitted?

90th percentile is better than 90% of the students who took the test, so yes, she will be admitted.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Perimeter of the composite shape = ½ of the circumference of a circle + perimeter of a rectangle - Length of the rectangle

= ½*2πr + 2(L + W) - L

Where,

r = 8

π = 3.14

L = 16

W = 12

Perimeter of the composite shape = ½(2*3.14*8) + 2(16 + 12) - 16

= 25.12 + 56 - 16

Perimeter of the composite figure = 65.12 inches

Area of the composite figure = ½(πr²) + L*W

= ½(3.14*8²) + 16*12

= 100.48 + 192

Area = 292.48 square inches
