Answer:$108

Step-by-step explanation:

Given

Bedroom door is [tex]9\ ft[/tex] tall

width of the door is [tex]3\ ft[/tex]

Rate [tex]R=\$4/ m^2[/tex]

The area of the door is  [tex]l\times w[/tex]

[tex]\Rightarrow A=9\times 3=27\ m^2[/tex]

Cost is given by

[tex]\Rightarrow C=27\times 4=\$108[/tex]

Answer:

A. The data show a negative linear relationship.

Step-by-step explanation:

According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis

So the following statements considered to be true

a. The volume represents the explanatory variable

b. Temperature would be strongly correlated to the ice cubes volume

c. As the correlation coefficient is near to -1

But it does not show the negative linear relationship

Therefore the correct option is a.

i is a good game and a good idea but it needs more people who are not the only ones that they were playing in a few weeks ago i dont have a game on joke

Question is not complete, so i have attached it.

Answer:

B: -2x² - 6x² - 6x + 3x + 3 + 2

Step-by-step explanation:

From the image attached, the given polynomial is;

3 - 6x - 2x² + 3x - 6x² + 2

For like terms to be next to each other, we have to rearrange it as follows;

-2x² - 6x² - 6x + 3x + 3 + 2

Like terms are x² and x, thus they are now arranged next to each other.

The only option that corresponds to our answer is option B

Answer:

Thanks so much!!

Step-by-step explanation:

Answer:

y=3x-5

Step-by-step explanation:

so step by step would go like this

1) add Y to the opposite side

3x=Y+5

2)Subtract 5 from the side with Y

y=3x-5

ok, So we know the length of  4/6 of the sides.....the ones we know are:

-4ft

-3ft

-9ft

-10ft

now to find the two missing sides.......we can see that one side is 5 because the other half is 4 ....which we already counted,.... (I'm talking about the unmeasured side over 9ft). Now to find the second...(the one closer to 10) since the already counted side is three and it's over 10 it has to be 7. so our missing ones are:

-7ft

-5ft

Now to add them together:

4+3+9+10+7+5=38

Lastly: REMEMBER TO ADD THE UNIT OF MEASUREMENT!!! Feet!!

That makes our answer 38ft!!

This means answer D or the last one is correct!!

HOPE I HELPED!!! HAVE AN AMAZING DAY/NIGHT!!!! PLEASE GIVE ME BRAINLIEST IF I HELPED YOU!!!

Answer:

38 feet.

Step-by-step explanation:

The length of the unmarked vertical side is 10 - 3 = 7 feet.

The length of the unmarked horizontal side is = 9 - 4 = 5 feet.

The perimeter = sum of the lengths of the sides

= 10 + 4 + 7 + 5 + 3 + 9

=  38 feet.

Answer:  The two angles add up to 180 so they are supplementary angles.  

The sum of their measures is 180 degrees.

Step-by-step explanation:

Plug in given value for x.  

x=20

(3x+50)=

(60+50)=110

110

(4x-10)=

80-10=70

70

There are several true things about these angles you can find from this information but I think you are looking for the answer at top.

Answer: it’s 544

Step-by-step explanation: if you divide 128/6 it will give you have much money he would make with one so it would be 8 and then if you multiply 68 times 8 you get 544

Answer: 672

Step-by-step explanation:

you already know that he/she washed 16 car for 128. so you divide 16 into 128 which is $8 ,then you multiply 8 times 64 which is 544  add 128+544=675

Answer:

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex]

Step-by-step explanation:

Let original cost of jacket = [tex]x[/tex]

original cost of skirt = [tex]y[/tex]

The equation will be

[tex]2x+3y=1800[/tex]

New cost of jacket = [tex]1.2x[/tex]

New costs of skirt = [tex]1.2y[/tex]

The equation will be

[tex]6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800[/tex]

The equations are

[tex]2x+3y=1800[/tex]  [tex]\times 0.8[/tex]

[tex]7.2x+2.4y=4800[/tex]

[tex]1.6x+2.4y=1440[/tex]

[tex]7.2x+2.4y=4800[/tex]

Subtracting the above two equations we get

[tex]-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600[/tex]

[tex]7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200[/tex]

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex].

Answer: 2

Step-by-step explanation:

Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

90 ÷ 45 = 2

and therefore:

9 ÷ 4.5 = 2

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5  + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4  = 360  {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

        15m = 360 - 15

        15m = 345 {Divide both sides by 15}

           m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°

Answer:

see explanation

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Sum the angles and equate to 360

m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is

15m + 15 = 360 ( subtract 15 from both sides )

15m = 345 ( divide both sides by 15 )

m = 23

Then

m + 5 = 23 + 5 = 28°

2m + 3 = 2(23) + 3 = 46 + 3 = 49°

3m + 2 = 3(23) + 2 = 69 + 2 = 71°

4m + 1 = 4(23) + 1 = 92 + 1 = 93°

5m + 4 = 5(23) + 4 = 115 + 4 = 119°

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- [tex]\frac{3}{2}[/tex], 0) and (x₂, y₂ ) = (0, [tex]\frac{3}{4}[/tex] )

m = [tex]\frac{\frac{3}{4}-0 }{0+\frac{3}{2} }[/tex] = [tex]\frac{\frac{3}{4} }{\frac{3}{2} }[/tex] = [tex]\frac{1}{2}[/tex] and c = [tex]\frac{3}{4}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] ( multiply through  by 4 to clear the fractions )

4y = 2x + 3 ( subtract 4y from both sides )

0 = 2x - 4y + 3 , that is

2x - 4y + 3 = 0 ← equation of line

Answer:

Step-by-step explanation:

A trianlge cannot be formed

Answer:

m<C can not be computed

Step-by-step explanation:

m∠A = 50°, c = 25, a = 19, m∠C=?

Using the Sine Law

a/sin m<A = c/sin m<C

Substitute the given values

19/sin50 = 25/sinC

19sinC = 25sin50

19sinC = 19.1511

sinC = 19.1511/19

sinC = 1.0079

C =  arcsin1.0079

Hence m<C can not be computed

y = -9

Ok so to write the equation of the line you will need the slope and y-intercept. Since we are given two-point we can easily find the slope by using this equation for slope formula:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

So now that we have our equation we can just plug in the numbers:

[tex]\frac{(-9)-(-9)}{5-(-3)}[/tex]

After subtracting you should get:

0/8

Since zero is in the numerator and you can't divide zero by anything, the slope is 0. We still need the y-intercept for the equation however since the slope is 0 there is no need to put anything else.

Then to find the y-intercept all you have to do is plug in one of the coordinatines into the slope equation to solve, for example, using the point (5,-9):

[tex](-9) = 5(0) + b[/tex]

B is the variable for the y-intercept. Also notice how I put 0 as our slope into the equation. Now all you have to do is solve for b. Which you would get b = -9. Since you have your slope and your y-intercept now you just write out your equatoin for the line which is:

y = 0x - 9

**Just write it as

y = -9

Answer:

Y = -9
