Answer the question for 20 points

Answer:

Step-by-step explanation:

Answer:

19

Step-by-step explanation:

231 - 7a = 98 = -7a + 231 = 98

Subtract 231 from both sides to get -7a = -133

Divide by -7 on both sides to get a = 19

Answer:

a = 19 is the correct solution.

Step-by-step explanation:

Step 1 : Start by simplifying both sides of the problem.

231 − 7a = 98

231 + − 7a = 98

−7a + 231 = 98

Step 2 : Next step is to subtract 231 from both sides

−7a + 231 − 231 = 98 − 231

−7a = −133

Step 3: Finally, divide both sides by -7.

( When I use the symbol /, it signifies I'm dividing.)

-7a/-7 = -133/-7

-133 divided by -7 equals 19

This shows that a = 19. I hope this helps! :D  

Using the knowledge of the measure of a semicircle, the measures in the circle given are:

a. m(DEF) = 152°

b. m(EFG) = 70°

c. m(CA) = 28°

Half of a circle is a semicircle = 180°.

Given the following:

a. m(DEF) = [m(CDE) - m(DC)] + [m(EF)]

m(DEF) = (152 - 39) + 39

m(DEF) = 152°

b. m(EFG) = m(EF) + m(FG)

m(EFG) = 39 + 31 = 70°

c. m(CA) = 180 - 152 (semicircle)

m(CA) = 28°

Answer:

The Cost of operating the theater if there are 100 people at a show is 20,000Rs.

Step-by-step explanation:

Theater is a place where the movies are shown in big screens and Speakers are used for the clear audio of the movie.

In a theater there will be 3 to 4 shows for a movie or different movie.

Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.

Consider a ticket cost of 200rs. For 100 people in a show ,

                              Cost = 200 × 100

                               Cost = 20,000.

Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

(c) 31/36

2. Blue - 1/3

Red- 4/15

Answer:

Step-by-step explanation:

Remark

If you drive 400 miles a month, and you get 19 miles per gallon, then you will need

gallons = miles / miles per gallon

Givens

m = 400

mpg = 19

Cost per gallon = 1.21

Solution

gallons = 400 / 19 = 21.05

You need to buy 21.05 gallons

1 gallon costs 1.21

21.05 gallons cost x            Cross multiply

x = 1.21 * 21.05

Answer: x = 25.47              Cost for 1 month's fuel.

Answer:

Length = 15ft

Width = 12ft

Step-by-step explanation:

First, re-read the problem until you acknowledge it and can put it into your own words.  

This is what I did:

 Find the area of a rectangle by first finding the length  and the width.  Note that:

L = Length  

W = Width

Find L and W

We will need formula:

P=2L+2W

A=LW

The length of a rectangle is 3 ft longer than its width :

L                             =    3             +         W                 Equation [1]

 "the perimeter of the rectangle is 30 ft"     means

            P                                = 54                           Equation [2]

     P = 54 = 2L + 2W                        

          54 = 2(3+W)  +  2W              

          54 = 6 + 2W   + 2W              

           54 = 6 + 4W                    

           48 + 4w

          12 ft = w

L = 3 + W        

          L = 3 + 12

         L = 15 ft

Area if needed

A = L*W

          A = (12 ft)*(15 ft)

          A = 180 sq ft

distibutitve property

Answer:

Formula for area of circle;

A = π[tex]r^{2}[/tex]

Where 'π' represents pi(3.14 or 22/7), and 'r' stands for the radius which is being squared.

What we know:

Plug in what we know;

A = π[tex]r^{2}[/tex]

(For pi I'll be using 3.14 instead of 22/7)

A = 3.14(14^2) ← (The symbol ' ^ ' means to the power of.)

A = 3.14(196)

A = 615.44, 615.44 centimetres is the area of this circle.

Answer:

≈[tex]615.44cm^2[/tex]

Step-by-step explanation:

So the equation for area of circle.

[tex]\pi r^2\\\pi 14^2[/tex]

So 14^2, or 14 x 14 is 196.

Now you can either keep it in terms of pi, 196pi, or times it by pi.

[tex]196*pi\\196*3.14\\615.44[/tex]

So the answer would be around 615.44cm^2

$15.48 for 12 lbs

Step-by-step explanation:

Check photo for work

The 12 pounds of ground beef cost is  $15.48.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the question

8 pounds of ground beef cost $10.32

i.e  8 pounds of ground beef = $10.32

    1  pounds of ground beef = [tex]\frac{10.32}{8}[/tex]

    1  pounds of ground beef = $1.29

Therefore,

12 pounds of ground beef = 1.29*12

12 pounds of ground beef = $15.48

Hence, 12 pounds of ground beef is of  $15.48.

j ÷ 9 = 5

Step-by-step explanation:

If the statement says, j divided by 9 is 5, it is obvious you are dividing in this situation.

So the equation is, j ÷ 9 = 5

The next part says solve for j.

This part is pretty easy; all you have to do is do the opposite operation and multiply 9 by 5.

So, j = 45

Answer: 6 cm

Step-by-step explanation:

The formula for the area of a parallelogram is

hb=a

Where

b is the base

h is the height (5 for this)

and a is the area (30 for this)

Let's sub these values into our equation

[tex]5b=30[/tex]

Divide both sides by 5 to isolate b

[tex]5b=30\\\frac{5b}{5} =\frac{30}{5} \\b=6[/tex]

The base is 6cm long.

Answer:

Base = 6 cm

Step-by-step explanation:

Given:

[tex]\text{Area of parallelogram} \text{ = 30 cm}^{2}[/tex]

[tex]\text{Height of parallelogram = 5 cm}[/tex]

Formula:

[tex]\text{Area of parallelogram} = \text{Base} \times \text{Height}[/tex]

Substitute the height and the area of the parallelogram:

[tex]:\implies 30 \ \text{cm}^{2} = \text{Base} \times 5[/tex]

Divide both sides by 5:

[tex]:\implies \dfrac{30}{5} = \dfrac{\text{Base} \times 5}{5}[/tex]

Simplify both sides:

[tex]:\implies 6 \ \text{cm} = \text{Base}[/tex]
