A theater has 40 rows of seats. There are 22 seats in each row. It costs $2.79 to deep clean each seat. How much does it cost to deep clean all the seats in the theater?

Answer: 33 degrees

Step-by-step explanation:

Since J and K are midpoints, JK must be parallel to GH.

If the linese are parallel, then angle IHG would equal angle IKJ because they would be corresponding angles. We can now set up an equation.

-7x + 75 = -4x + 57

Combine like terms:

3x = 18

Divide both sides by 3:

x = 6

Therefore, -7x + 75 = -7*6 + 75 = -42 + 75 = 33

Step-by-step explanation:

2/3=4/6

30/6-9/6=21/6

Answer:

1$

Step-by-step explanation:

Her total amount is 40$

She then buys the tires(tires = 21$) so she bought that subtract 21$ from 40$ 40$ - 21$=19$

She next wanted to buy a bell so she did the bell was 5$ so subtract 5$ from 19$ 19$-5$=14$ left

So remember she has 14$ left and she is buying a basket which is 13$ so her buying the basket is remaining her with 1$ because basket is 13$ and she has 14$ so what is 14$-13$ it is 1$  and there's your answer.

         1$

Answer:

3.5 miles per hour of speed

Step-by-step explanation:

Given:

To find:

0.875                      15

             x                           60

Answer: Lien walked 3.5 miles per hour of speed.

Step-by-step explanation:

Distance Lien walked = 7/8 of a mile = 0.875 miles

Time of walking = 1/4 of an hour = 15 minutes

Distance in miles     Time in minutes

          0.875                      15

             x                           60

Calculations:

15x = 0.875 * 60

15x = 52.5

x = 52.5/15

x = 3.5

Answer:

D. y=x+5

Step-by-step explanation:

Find the slope of the line. Remember to use equation: m=y2−y1/x2−x1

m= 5-(2)/0-(-3)

Simplify both numerator and denominator, then divide. You'll get m=1

Use the slope 1 and a given point (−3,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1).

y−(2)=1⋅(x−(−3))

Simplify the equation.

y−2=1⋅(x+3)

Solve for y by multiplying x+3 by 1.

y−2=x+3

Move everything that doesnt contain y to the right by adding 2 to both sides of the equation

y=x+3+2

and then added 3 and 2.

y=x+5

Answer:

y = -0.71

x = 8

Step-by-step explanation:

Bring variables on one side of the equation

18.3y - 8.4y = -14.6 + 7.6

4.1x - 0.7x = 25.9 + 1.3

Solve for the variable

9.9y = -7

y = -70/99

3.4x = 27.2

x = 8

x + y = 71.5

x = 47.8

y = 71.5 - 47.8

71.5 - 47.8 = 23.7

y = 23.7 pounds

Answer:

6(y - 3)(2y + 5)

Step-by-step explanation:

12y^2 - 6y - 90

Factorize

6(2y^2 - y - 15)

Split the term

6(2y^2 - 6y + 5y - 15)

Regroup terms

6((2y^2 - 6y) + (5y - 15))

Factorize

6((2y(y - 3) + 5( y - 3))

Factorize

6(y - 3)(2y + 5)

Answer:

[tex]6(y-3)(2y+5)[/tex]

Step-by-step explanation:

[tex]12y^2-6y-90[/tex]

First, factor out the common term of 6:

[tex]\implies 6(2y^2-y-15)[/tex]

To factor [tex](2y^2-y-15)[/tex]:

Multiply the coefficient of [tex]y^2[/tex] by the constant:

[tex]\implies 2 \times -15 = -30[/tex]

Now find factors of -30 that sum to the coefficient of [tex]-y[/tex], i.e. -1

Factors of 30:  1, 2, 3, 5, 6, 10, 15, 30

So factors of -30 that sum of -1 are:  -6 and 5

Rewrite the middle term of [tex](2y^2-y-15)[/tex] as [tex]-6y + 5y[/tex]:

[tex]\implies 2y^2-6y+5y-15[/tex]

Factor each pair of terms:

[tex]\implies 2y(y-3)+5(y-3)[/tex]

Factor out the constant term:

[tex]\implies (y-3)(2y+5)[/tex]

Therefore, the final factorization is:

[tex]\implies 6(y-3)(2y+5)[/tex]

Answer:

Step-by-step explanation:

We are told to model the number of students in the club. That is the dependent variable, so we will assign 'y' to that quantity. The number of students in the club is a function of the number of weeks since it was formed, so we can assign 'x' to that independent variable.

The initial value of y is 6, and it increases by 3x (that is, 3 students each week). The model of the number of homework club students can be ...

  y = 3x +6

Answer:

A semicircle is drawn with AC as diameter. If AB = BC = 7 cm, find the area of the shaded region. Take π = 22/7. 25. A circular field has perimeter 660 m.

Using the formula for area of circle and right angled triangle, we find that area of shaded region is  96[tex]cm^2[/tex].

Area of circle = [tex]\pi r^2[/tex]

where, r is the radius of circle.

Area of right angled triangle = [tex]\frac{1}{2} * base *height[/tex]

The area of shaded region is given by =

= area of semicircle with AB as diameter + area of semicircle with BC as diameter + area of triangle ABC - area of semicircle with AC as diameter

Now,

area of semicircle with AB as diameter =

AB = diameter  =  12cm

radius = 6 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 6^2 = 56.52[/tex]

area of semicircle with BC as diameter =

BC = diameter  =  16cm

radius = 8 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 8^2 = 100.48[/tex]

area of semicircle with AC as diameter =

AC = diameter  =  20cm

radius = 10 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 10^2 =157[/tex]

area of triangle ABC =

AB = base = 12cm

BC  = perpendicular = 16 cm

area(ABC) = [tex]\frac{1}{2}*12*16 = 96[/tex]

The area of shaded region is given by = 56.52 + 100.48 + 96 - 157 = 96[tex]cm^2[/tex]

Answer:

44.4 meters

Step-by-step explanation:

Using 1 foot = 30 cm

convert 148 feet to centimeters by multiplying.

148ft × 30cm/1ft

= 148 × 30

= 4440 cm

Then convert cm to meters by dividing by 100.

1 meter = 100cm

4440cm × 1m/100cm

= 4440/100

= 44.4m

148 feet is 44.4m

Answer:

15g

Step-by-step explanation:

Method A: Calculate the percent first

If you decrease an amount by 25%, you end up with 75% of the amount.

75% of 20g = 0.75 × 20g = 15g

Method B: Calculate the decrease first

We start with 20g. To decrease 20g by 25%, we calculate 25% of 20g.

25% of 20g = 0.25 × 20g = 5g

The decrease amount is 5g.

Now we subtract 5g from 20g.

20g - 5g = 15g

Answer:

y = 6.3

Step-by-step explanation:

ΔLMN ~ ΔABC

The two triangles are similar which means the sides have the same proportions. To put it simply, one shape is just an enlargement of the other.

In this case, triangle ABC is an enlargement of triangle LMN so we can work out a scale factor.

To work out the scale factor, we can do 10 ÷ 7 = 1.4285714... To find y, all we have to do is divide 9 by the scale factor to get 6.3.

Hope this helps!

Ratio remains same as triangles are similar

Option D

Answer:You would wind up with (3, 2). When we move the point to the left, we subtract the amount that we move. 5 - 2 = 3And when we move down, we also subtract by that number in the y portion. 4 - 2 = 2(3, 2)

Answer: 100pi

Step-by-step explanation:

Step-by-step explanation:

the line is

20x - 17y = 15

I am not sure what your teacher uses as "standard form".

the works is split between "point-slope" and "slope-intercept" form as "standard".

I usually pick "slope-intercept" :

y = ax + b

with a being the slope and b being the y-intercept.

in any case, we can find the x-intercept without bringing the line equation to one of these forms.

because x-intercept simply means that y = 0.

and for y=0 the original equation is then

20x - 17×0 = 15

20x = 15

x = 15/20 = 3/4
