Answer:

I'm Pretty Sure it is $16.20

Step-by-step explanation:

First, you add 2.50 + 0.20 and you get 2.70. Then, you get 2.70 x 6 miles and you get 16.20. Hope this helps! :)

Step-by-step explanation:

line passes through the point (5,0) and another one (0,3)

equation of the line passing through two points is

x-x1/x2-x1=y-y1/y2-y1

so

x-5/0-5=y-0/3-0

(x-5)*3=y*(-5)

3x-15+5y=0

this is the equation of the line shown in the graph

9514 1404 393

Answer:

  y = -10

Step-by-step explanation:

Using the point-slope form of the equation for a line, we can write the equation as ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -2 = -3(x -5)

Using the values for the other point, this becomes ...

  y -2 = -3(9 -5)

  y = -3(4) +2

  y = -10

Answer:

slope = -6

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

The line is moving down negatively, and by using rise over run, we can determine that the slope is -6/1

Given ,

AB = BC

BC = CA

CA = 6 cm

This is an equilateral triangle as the first side is equal to the second side and the third side is equal to the second side which is equal to the first side . As all the sides are equal to 6 cm , this triangle is said to be an equilateral triangle .

∴ Triangle ABC is an equilateral triangle , where :- AB = BC = CA = 6 cm .

Answer:

1. m<5 = 114

2. m<6 = 68

3. m<2 = 64

Step-by-step explanation:

Question 1:

<1 = <4 because of Vertical Angles Theorem

< 4 = <5 because of Alternate Interior Angles Theorem

Hence, <1 = <5

Since m<1 = 114: m<5 = 114.

Question 2:

<3 = <6 because of Alternate Interior Angles Theorem

Since m<3 = 68: m<6 = 68

Question 3:

<2 = <7 because of Alternate Exterior Angles Theorem

Since m<7 = 64: m <2 = 64

Answer:

The Student has good posture on the chin rest but The way that there are not standing straight up and how there holding the bow is incorrect

Step-by-step explanation:

Sitting up straight, turn your head enough that your nose lines up with the left foot. Drop your chin and place the violin so that it's also aligned with your left foot. Hold your spine straight and relax into this position; you should be able to keep the violin steady using only your chin.

Answer:

Step-by-step explanation:

Circle:

diameter = 30 ft

r = 30/2 = 15 ft

Area = πr²

         = 3.14 * 15*15

         = 706.50 square feet

Triangle:

base (b) = 30 ft

height (h) = 20 ft

Area = [tex]\frac{1}{2}bh[/tex]

        [tex]=\frac{1}{2}*30*20\\\\=30*10[/tex]

       = 300 square feet

Area of four triangles  = 4 * 300

                                    = 1200  square feet

Area to be painted blue = area of circle + area of 4 triangles

                                        = 706.50 + 1200

                                        = 1906.50 square feet

Area painted by one bucket blue paint  = 350 sq. feet

Number of paint buckets needed = 1906.50 ÷ 350

                                                       = 5.44

                                                       = 6

6 buckets of blue paint is needed.

Cost of 6 buckets of blue paint = 85.50 * 6

                                                    = $ 513

Each part of the design needs two coats.

So Cost for  two coats = 2 * 513

                                     = $ 1026

Square:

Side  =  40 ft

Area of square = side *side

                         = 40*40

                         = 1600 sq. ft

Area of square to be painted yellow = area of square - area of circle

                                                           = 1600 - 706.50

                                                          = 893.50 sq.ft

Area painted with  one bucket of yellow paint = 250 sq. ft

Number of yellow paint buckets needed = 893.50 ÷ 250

                                                                    = 3.574

                                                                    = 4

4 buckets of yellow bucket is needed

Cost of 4 buckets of yellow bucket = 64.50 * 4

                                                          = $ 258

Each part of the design needs two coats.

So Cost for  two coats = 2 * 258

                                     = $ 516

Answer:

6 is the answer since a line is 180 degrees and it gives you 40 degrees and 90 degrees via the square symbol. you add 40 to 90 to get 130 so 7k + 8 has to equal 50.

Answer:

31

Step-by-step explanation:

To solve this problem, we must find the lowest common multiple of 21, 35 and 63

   Find the prime factors of the number;

 Prime factors of 21  = 3 x 7

                            35 = 3 x 5

                            63 = 3 x 3 x 7

  The lcm = 3 x 3 x 5 x 7 = 315

The numbers between  1 and 10, 000 divided by these three numbers;

   First number  = 315

    Last number  = 9765

Now the total number:

      = [tex]\frac{first number - last number }{315} + 1[/tex]

      = [tex]\frac{9765 - 315}{315}[/tex] + 1

     = 30 + 1

     = 31

Answer:

The equation should be, 65m+25=c

Answer: it’s going to be c=65m+25

Step-by-step explanation:

A) The loan amount you can afford is, $177,690.52

B) There will be paid a total of $486,000 to the loan company over the course of 30 years.

C) $308,309.48 of the total money you will pay the loan company is interest.

Given that,

You can afford a $1350 per month mortgage payment.

And, found a 30-year loan at 7% interest.

A) Using the formula for calculating the monthly mortgage payment, we can rearrange it to solve for the loan amount:

Loan Amount = [tex]\frac{Monthly Payment }{(Monthly Payment * (1 + (\frac{1}{1+Monthly Payment )^{Number of payments} } }[/tex]

Plugging in the given values:

Monthly Payment = $1350

Monthly Interest = 7% / 12

= 0.00583

Number of Payments = 30 years × 12 months

= 360

Hence,

Loan Amount = [tex]\frac{1350}{(0.00583 (1 + \frac{1}{1+ 0.00583)^{360} } )}[/tex]

By evaluating this expression,

the loan amount you can afford is,

$177,690.52

B) The total money you will pay the loan company,

Total Money Paid = Monthly Payment × Number of Payments

Total Money Paid = $1350 × 360

= $486,000

Therefore, you will pay a total of $486,000 to the loan company over the course of 30 years.

C) the amount of money which is interest,

Interest Paid = Total Money Paid - Loan Amount

Interest Paid = $486,000 - $177,690.52

= $308,309.48

Hence, $308,309.48 of the total money you will pay the loan company is interest.
