Answer 1

Answer:

0.225989

Step-by-step explanation:

3x+9+x-11=180

4x-3=180

4x=180-3

4x/4x=177/4x

0.225989

Answer 2

Answer:

=78 degrees

Step-by-step explanation:

complementary angles add up to 90 degrees

A + B = 90

3x + 9 + x - 11 = 90

3x + x + 9 - 11 = 90

4x - 2 = 90

collect like valuables

4x = 90 + 2

4x = 92

x =23

angle A = 3x + 9

             = (3 x 23) + 9

             = 69 + 9

             = 78

2/3(x-2)=4x
2(x-2)/3 = 4x
2x-4/3 = 4x
2x-4/3 - 4x = 4x - 4x
2x - 4 / 3 - 4x = 0

Okay so we have

$1.60 x .10 = .16

1.60 - .16 = $1.44

so

1.44 x 4 = $5.76

1.44 / 2 = .72

$5.76 + .72 = $6.48

so your answer is $6.48 [B]

Step-by-step explanation:

Vedant runs around a square park of side 42m, three times. Rehan runs around a rectangular park of length 40m and breadth 18m, five times. Who covers more distance? By how much?

Answers

Answer:

Rehan;

76m

Step-by-step explanation:

Distance covered by running around square park :

Perimeter of square = 4s ; s = side length of square

Perimeter = 4 * 42m = 168 m

Total distance covered = 168m * 3 = 504m

Distance covered by running around rectangular park :

Perimeter of rectangle = 2(l + w) ;

Perimeter = 2(40 + 18) = 2(58) = 116 m

Total distance covered = 116m * 5= 580m

580m - 504m = 76m

Rehan covered more distance

The value of W is inversely proportional to m. If w=8 then m=25, What is m when W is 20?Show me all the steps please?

Answers

Answer:

m = 10

Step-by-step explanation:

The values of w is inversely proportional to m

Mathematically the above statement is expressed as:

w ∝ 1/m

w = k × 1/m

w = k/m

Where k is the Proportionality Constant

First step

Solve for k

If w=8 then m=25

w = k/m

8 = k/25

Cross Multiply

k = 25 × 8

k = 200

Second step

what is m when w=20? Show me the steps please

We solve for m

w = k/m

k = 200

20 = 200/m

Cross Multiply

20m = 200

m = 200/20

m = 10

If you are being paid $55 for a days work which is an 8 hour shift how much would you get paid if you only worked 6 hours?

Answers

Answer:

You would get paid $41.25 if you only worked 6 hours.

Step-by-step explanation:

In order to find the answer, first you have to find the amount you are paid per hour by dividing the amount paid per day by 8 hours:

$55/8=$6.875

Then, you have to multiply the amount per hour for 6 to determine the amount you would get paid if you only worked 6 hours:

$6.875*6=$41.25

According to this, the answer is that you would get paid $41.25 if you only worked 6 hours.

What are Linear Equations?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution

On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.

Given data ,

Let the linear function be represented as A

Now , the value of A is

The total cost for the SUV is given by

y₁ = 2,840x + 17,980

And , the total cost for the car is

y₂ = 3,210x + 17,980

when x = 2 years

y₁ = $ 23,660

y₂ = $ 24,400

The cost of the car is greater than cost of the SUV

Hence , the linear equations are solved
