It took a plane 2 hours to fly from Dallas to New York with the headwind and 1.5 hours to return with the tailwind. If the speed of the wind was 30 mph, how far apart are the two cities?

Answers

Answer:

The distance between the two cities is 360 miles.

Step-by-step explanation:

Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:

d/a+30=1.5

d=1.5a+45

and

d/a-30=2

d=2a-60

2a-60=1.5a+45

.5a=105

a=210

d/210-30=2

d=360

The distance between the two cities is 360 miles.

A circle has an area 225π square inches. If the radius of the circle is multiplied by 6, then what is the area of the new circle formed?

Answers

Answer:

8100π in. Squared

Step-by-step explanation:

i.d.k its a guess

Pi(r)^2 is area of a circle. Pi(r)^2=225(pi), solve for r. R=15. 15x6=90. New radius=90. Using area of circle formula, Pi(90)^2=8100 (pi)

As the graph shows, the amount of tax you pay when you buy a new motorcycle is directly proportional to the motorcycle's purchase price.

How much tax would be paid on a new motorcycle that is priced at $15,000?

Answers

I would say 1,000 for tax

either $1000 or $937.50, either would make sense, but on the graph no points are on an exact number, so i’d think 937.50.

On the dashboard of Josh's car, there is a clock and an odometer. The odometer tells how many total miles the car has been driven. Josh glances at his car's dashboard (A), and then looks back a few minutes later (B). (Pls I need help.)

Answers

a) Between the two times, Time A and Time B, 12 minutes passed (total time).

b) During this time, Josh drove his car for 10.8 miles (total distance).

c) This means that Josh was driving at an average rate (speed) of 0.9 miles per minute.

What is the average rate?

The average driving rate refers to the speed at which Josh was driving his car.

The average rate is the quotient between the total distance covered and the total time taken to cover the distance.

The distance, time, and speed formula are Distance = Time x Speed.

Therefore, Speed = Distance/Time.

Reading on odometer at 9:53 = 52,604.1

Reading on odometer at 10:05 = 52.614.9

Distance covered = 10.8 miles (52.614.9 - 52.604.1)

Difference in time = 12 minutes (10:05 - 9:53)

Average speed = 0.9 miles per minute (10.8/12)

Answers

Answer:

whats the question here?

Step-by-step explanation:

Answer:

Hi there!

In order to answer your question, you'll need to use the cross product method:

1 cup water → 1/4 cup sugar

10 cups water → X cup sugar

((1/4) × 10) ÷ 1 = X cups sugar

2.5 ÷ 1 = X cups sugar

2.5 = X cups sugar

Your answer is : Using 10 cups of water, you should add 2 and a half cups of sugar so that the large batch tastes the same as the test batch.

There you go! I really hope this helped, if there's anything just let me know! :)

For what values of r will the area of the shaded region be greater than or equal to 12 square units? Write your answer as an inequality.

STEP 2: The values are .

Answers

Answer:

Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!

Our equation would be 13 + 13 + 7 + 7 = 40 inches

Step-by-step explanation:

The values of r for which the shaded region will be greater than or equal to 12 square units is;

r ≥ 8

We can see a rectangle and a triangle in the given image.

With the triangle being the unshaded portion of the rectangle.

Thus;

Area of shaded portion = Area of rectangle - area of rectangle.

We know that formula for area of rectangle is;

A_r = length × width

Thus; A_r = 3 × r

A_r = 3r

Area of a triangle is;

A_t = ½ × base × height

A_t = ½ × r × 3

A_t = ½(3r)

Thus;

Area of shaded portion = 3r - ½(3r)

Area of unshaded portion = 1.5r

We are told that the area of the unshaded region should be greater than or equal to 12. Thus;

1.5r ≥ 12

r ≥ 12/1.5

r ≥ 8

Associative Property:

Identity Property:

Additional and Multiplication.

Distributive Property

Step-by-step explanation:

Communitive Property:

Addition; When two numbers are added, the sum is the same regardless of the order in which the numbers are added. (3 + 2 = 5 or 2 + 3 = 5)

Multiplication; When two numbers are multiplied together, the product is the same regardless of the order in which the numbers are multiplied.

(4 x 3 = 12 or 3 x 4 = 12)

Associative Property:

Addition; When three or more numbers are added, the sum is the same regardless of the way in which the numbers are grouped.

6 + (4 + 3) = 13 or (6 + 4) + 3 = 13

Multiplication; When three or more numbers are multiplied, the product is the same regardless of

the way in which the numbers are grouped.

6 x (4 x 3) = 72 or (6 x 4) x 3 = 72

Identity Property:

Addition; The sum of any number and zero is that number.

(10 + 0 = 10)

Multiplication; The product of any number and one is that number.

(33 x 1 = 33)

Distributive Property:

The sum of two numbers times a third number is equal to the sum of each addend times the third number. 6(3 + 4)

(Multiply 6 by both numbers, 6 x 3 = 18 and 6 x 4 = 24, and then add the sums; 18 + 24 = 48.
