Step-by-step explanation:

Answer: Rahul earns 3.5 dollars more per hour than Arun.

Step-by-step explanation:

17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.

Use the two points, (10,208) and (20, 416)

Use the formula for calculating slope:

416-208=208

20-10=10

---------------------

208/10= 20.8

Rahul's equation can be set up like this:

y=20.8x

Subtract:

20.8-17.3=3.5

Therefore, Rahul earns 3.50 dollars more per hour than Arun.

Step-by-step explanation:

Answer:

B. 30

Step-by-step explanation:

The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.

85 = 3x - 5

We need to solve for x.

First, combine like terms by adding 5 to both sides.

90 = 3x

Now we want to isolate x by dividing both sides by 3.

x = 30

This is your answer.

Let's check our work by plugging x back into our equation.

85 = 3x - 5

85 = 3(30) - 5

85 = 90 - 5

85 = 85

Your answer is correct.

Hope this helps!

Answer:

Option D 78.5

Step-by-step explanation:

Circumference= 2*Pi*r

                        = 2 * 3.14 * 12.5

                        = 78.5

The circumference of the circular car tire is 78.5 inches.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

Radius of a circular car tire = 12.5 inches

We have to find the circumference.

The given car tire is circular in shape.

The formula to find the circumference of a circular shape is,

Circumference = 2πr, where r is the radius of the circle.

Substituting the given value of r,

Circumference = 2π × 12.5

                         = 25π

Given to use 3.14 for π.

Circumference = 25 × 3.14 = 78.5 inches.

Hence the required circumference of the circular car tire is 78.5 inches.

Probability of not green: 1/2

0.5*4=2

Answer:

2 times

Step-by-step explanation:

The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.

Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

Answer:

the second table

Step-by-step explanation:

if you plot all the points on a graph, the second function is the only one with a linear function. a linear function is a straight line.

It will take 50 minutes for the two containers to have the same amount of water.

Based on the information given, the equation to solve the question will be:

800 - 6m = 1000 - 10m

Collect like terms

-6m + 10m = 1000 - 800

4m = 200

Divide both side by 4

4m/4 = 200/4

m = 50

Therefore, it'll take 50 minutes.

Answer:

22, 608 ft squared

Step-by-step explanation:  

V = (pi) r squared  times h

Volume is a three-dimensional scalar quantity. The amount of corn in cubic feet that the farmer's silo can hold is 7200π ft³ or 22,619.467 ft³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Suppose that the radius of a right circular cylinder is 'r' units. And let its height be 'h' units.

Then, its volume is given as:

V = π × r² × h

The right circular cylinder is the cylinder in which the line joining centre of top circle of the cylinder to the centre of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

Given that the silo has a height of 50 feet and a radius of 12 feet. Therefore, the volume of the cylindrical silo can be written as,

The volume of the silo = π × r² × h

                                      = π × (12 ft)² × 50ft

                                      = 7200π ft³

                                      = 22,619.467 ft³

Hence, the amount of corn in cubic feet that the farmer's silo can hold is 7200π ft³ or 22,619.467 ft³.

Answer:

Step-by-step explanation:

Old Value:  5

            New Value:   16.1

16.1-5=11.1

11.1 divided by 5= 2.22

2.22/1 x 100=222%

222% increase

Old Value:  40

            New Value:  57.6

57.6-40=17.6

17.6 divided by 40= 0.44

0.44/1 x 100= 44%

44% increase

Old Value:  60

           New Value:   63.6

63.6-60=3.6

3.6 divided by 60= 0.06

0.06/1 x 100= 6%

6% increase

Old Value:  110

           New Value:   13.2

13.2-110= -96.8

-96.8 divided by 110= -0.88

-0.88/1 x 100= 88%

88% decrease
