Answer:  21. Perimeter = 48    22 . Perimeter= 36    23.  Perimeter= 72

Step-by-step explanation:

First  you need to find the side length using the area of each of the squares. We know that to find the area of a square you will  have to square one of the side lengths, that means that to find the side length, we will need to find the square root of the area.

21 .  Find the square root of  144.  

    [tex]\sqrt{144}[/tex]    = 12

  The side length is 12 so multiply  it by 4 to find the perimeter because the perimeter is the distance around the shape.  All the side length's of a square are the same and there four sides so multiply it by 4 to find the  perimeter.

   Perimeter = 12 * 4

   Perimeter  = 48  

22.  The same thing with this one, find the square root  and multiply the side length by 4.

   [tex]\sqrt{81}[/tex]  =  9  

 Perimeter = 9 *4  

  Perimeter = 36

23.    [tex]\sqrt{324}[/tex]  = 18  

   Perimeter =  18 * 4  

    Perimeter =  72

Answers

Answer:

that first guy its trash. The real answer is 47

Step-by-step explanation:

It is 47 because the rhombus ia making 4 triangles which are all the same shape, meaning all triangles make up 180 degress. we see one angle is 90 degrees since the four trianglea meet at tue middle. so we subtract 43 degrees from 90 which makes 47 degrees.

Answers

Note: Your statement and answer options are a little ambiguous, so I am assuming you want to determine the inverse of f(x)=-x+2.

As the process is the same, so it would still clear your concept.

Answer:

[tex]\mathrm{Inverse\:of}\:-x+2:\:\:2-x[/tex]

Step-by-step explanation:

Given the function

[tex]f(x)=-x+2[/tex]

We know that a function h is the inverse function of f if for y=f(x), x=h(y)

Determining the inverse

[tex]y=-x+2[/tex]

Replace x with y

[tex]x=-y+2[/tex]

solve for y

[tex]y=2-x[/tex]

Therefore,

[tex]\mathrm{Inverse\:of}\:-x+2:\:\:2-x[/tex]

Sean's father decided that the number of hours Sean should study daily is equal to the equation y + 4 16. where y is the

number of study hours and z is the number of relaxation hours. Sesn's mother believes that the number of hours Sean should study

dally should be equal to the equation 2y + 5z = 32. Sean's parents have decided to use both equations to determine the number

of hours Sean should study and relax What is an equivalent equation to the addition of Sean's mother's equation and Sean's father's

equation? Select all that apply.

Answers

Answer and explanation:

We add both equations to get a simultaneous equation

y+4z=16

2y+5z=32

We solve the equations using elimination method:

Multiply equation 1 by 5 and equation 2 by 4 to cancel out z

5y+20z=80

8y+20z=160

-3y=-80

Y=26.7

Substitute y=26.7 in equation 1

26.7+4z=16

4z=16-26.7

z= -2.67

y+z=26.7+(-2.67)= 24.03

Many businesses and organizations insist that official communications use professional-looking fonts, such as Times New Roman. Fonts characterized as less professional, such as Comic Sans, should be avoided. A student would like to determine if font choice makes a difference in the average grade on a typed response in English classes. There are currently four English classes available from which the student can collect data, and each class has a similar writing assignment. The student considers two methods for collecting data.

Method A: At the start of the assignment, students choose a font, either Times New Roman or Comic Sans, and then complete the assignment.

Method B: At the start of the assignment, students are randomly assigned one of two fonts, either Times New Roman or Comic Sans, and then complete the assignment.

In both methods, the teachers grade the papers received, and the mean grade for each font is determined.

Which method describes an experiment?

Method A is an experiment because the students choose their own font.
Method B is an experiment because the students are randomly assigned a font.
Both methods describe experiments because both fonts are used on the assignment.
Neither method describes an experiment because a third font should be included for comparison.

A loan of $36,000 is made at 6.75% interest, compounded annually. After how many years will the amount due reach $57,000 or more?

Answers

Answer:

After 7.04 years the amount will reach $57,000 or more

Step-by-step explanation:

The rule of the compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where

A is the new valueP is the initial valuer is the rate in decimaln is the period of the timet is the time

∵ A loan of $36,000 is made at 6.75% interest, compounded annually

P = 36,000

r = 6.75% = 6.75 ÷ 100 = 0.0675

n = 1 ⇒ compounded annually

∵ The amount after t years will reach $57,000 or more

A = 57,000

→ To find t substitute these values in the rule above

∵ 57,000 = 36,000 [tex](1+\frac{0.0675}{1})^{(1)(t)}[/tex]

∴ 57,000 = 36,000 [tex](1.0675)^{t}[/tex]

→ Divide both sides by 36,000

∵ [tex]\frac{19}{12}[/tex] =  [tex](1.0675)^{t}[/tex]

→ Insert ㏒ in both sides

∴ ㏒( [tex]\frac{19}{12}[/tex] ) = ㏒ [tex](1.0675)^{t}[/tex]

→ Remember ㏒[tex]a^{n}[/tex] = n ㏒([tex]a[/tex])

∵ ㏒( [tex]\frac{19}{12}[/tex] ) = t ㏒(1.0675)

→ Divide both sides by ㏒(1.0675)

∴ 7.035151337 = t

t ≅ 7.04

After 7.04 years the amount will reach $57,000 or more

In the xy-plane, the line with equation
y = 4x - 28 crosses the x-axis at the point
with coordinates (a, b). What is the value
of a?
A. -28
B. -2
C. O
D. 5
E. 7​

Answers

Answer:  E.  7

=======================================================

Explanation:

Any point on the x axis always has its y coordinate equal to 0.

Plug in y = 0 and solve for x

y = 4x-28

0 = 4x-28

4x-28 = 0

4x = 28

x = 28/4

x = 7

Therefore, the point (7, 0) is on the line y = 4x-28 and also on the x axis. This is known as an x intercept.

Comparing (7, 0) this to (a, b) shows that a = 7 and b = 0.
