Rachel can walk 2.5 miles in 40 minutes at this rate how far can she walk in one hour

Answers

My answer~

3.75 miles

Explination~first you would start by finding out how many miles she walks in 1 minute by dividing 2.5 by 40

2,5 ÷ 40 =

0.0625

Then you would times that by 60, because 60 minutes equals 1 hour

0.0625 × 60 =

3.75

So, Rachel can walk 3.75 miles in 1 hour :))------------------------------------------------------------------------

He pays 18% income tax on everything he earns over $8200.
a Work out how much income tax he pays.
b Work out what percentage of his income he pays in tax.
If the income tax rate is increased to 21%, how much more tax will Sam pay?

Determine if the graph shows two quantities that vary directly. If possible, determine the constant of proportionality using the formula K = y/x

Answers

Answer:

Option C is correct option.

Step-by-step explanation:

We need to find k constant of proportionality

In the graph below let us take the values of x and y

x=150 , y=50

x=300, y=100

x=450, y=150

Now finding k using the formula: [tex]k=\frac{y}{x}[/tex]

Putting values of x and y to find k

For x=150 , y=50 k = 50/150, k =1/3

For x=300, y=100 , k=100/300 , k=1/3

For x=450, y=150, k= 150/450 , k=1/3

Since for values of x and y, k = 1/3 is constant so, the graph shows two quantities that vary directly.

So, Option C is correct option.

If a car travels 180 miles in 4 hours, how many miles would it go in 6?

Answers

Answer:

270

Step-by-step explanation:

First, to find how far the car will go in one hour, you do 180 divided by 4. We already know that the car drives at a constant rate. If you do 180 divided by 4, you get 45. Then you multiply 45 by the amount of hours (6) to get 270
