What is the application ratio and proportion?

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

Given that,

The total number of pies is 1,954.

Number of types of pie = 2.

Each type of bakery can be found by taking the ratio of the number of pies and number of types of pie as follows,

1954/2

= 977

Hence, the number of each type of pie made by the bakery is 977.

A. All motion is relative to the frame of reference chosen for measurement.

Step-by-step explanation:

Student 1 riding in the car is going at a certain speed. He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.

The difference in estimates is due to their frames of reference.

Answer: A. All motion is relative to the frame of reference chosen for measurement.

Catalin works in an office. One week he divides his time between these tasks:

1/4 of his time in meetings
5/8 of his time writing reports
the rest of his time doing the accounts
He spends a total of 6 hours doing the accounts

Find the total number of hours he works in the week. How would I go about solving this problem?

Answers

Answer:

Catalin works 48 hours during the week.

Step-by-step explanation:

Since Catalin divides his weekly worktime using 1/4 of his time in meetings, 5/8 of his time writing reports and the rest of his time doing the accounts, and he spends a total of 6 hours doing the accounts, to find the total number of hours he works in the week the following calculation must be performed:

1/4 + 5/8 = X

1/4 + 2.5 / 4 = X

3.5 / 4 = X

0.5 = 6

(4 / 0.5) x 6 = X

8 x 6 = X

48 = X

Therefore, Catalin works 48 hours during the week.

Divide 64 by multiple numbers, and if they divide evenly that’s how many will be in each bag for the number of bags (number you divided by). For example, dividing 64 by 8 (bags) would be 8 cookies in each bag. You can do this with multiple numbers as long as it goes in evenly

Answer:

9

Step-by-step explanation:

The left side of the triangle is 20 units long, the bottom portion is 8 units long.

This means the top portion must be 12 units long, 20 - 8 = 12.

The ratio between the left and right side has to be the same because they are two straight lines.

So if the ration is 8 to 6 or 8/6 which reduces to 4/3 then your ration is 12 to x.

So if... 4/3x=12 then

(3)4/3x = 12(3) multiply both sides by 3

4x = 36 the divide both sides by 4

x = 9

To check you can multipy your answer, in this case 9 by 4/3.

(9)(4/3)  =

(9 x 4)/3 =

36/3 = 12

You did it! Hope this helped.

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?

Answers

Answer: 128.7 inches

Step-by-step explanation:

Josh's height is 66 inches.

When he jumps with a running start, he can jump as far as 195% of his height.

The length he can jump is therefore 195% multiplied by his height:

= Josh height * 195%

= 66 * 195/100

= 128.7 inches

Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?

Answers

Answer 9.5

you do the pyragtaham theory thing its A(squared) + B (squared) = C squared

you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5

The distance from the top of the ladder to the ground is 9.54 ft.

What is a right triangle?

"It is a triangle whose one of the angle is 90°"

What is hypotenuse?

"The longest side of the right triangle is called as hypotenuse."

What is Pythagoras theorem?

"For a right triangle,

c² = a ² + b²,

where c = hypotenuse and a, b are other two sides of right triangle."

For given example,

Gwendolyn placed a ladder against the side of her house.

This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.

Let 'a' be the hypotenuse of triangle, 'b' be the base and  'd' be the distance from the top of the ladder to the ground

⇒ a = 3 ft. and b = 10 ft.

Using Pythagoras theorem,

⇒ b² = a² + d²

⇒ 10² = 3² + d²

⇒ 100 = 9 + d²

⇒ d² = 91

⇒ d = 9.54 ft.

Therefore, the distance from the top of the ladder to the ground is 9.54 ft.

The polygons are similar. Find the values of
the variables. Write an equation and solve,

Answers

Answer:

x = 12, y = 8

Step-by-step explanation:

Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday. What percent of 8th graders did not try out for football?
