If y varies inversely as the square ofx, and y = 1/8 when x = 1, find y when x = 5

Answers

Answer 1

Answer:

25/8

Step-by-step explanation:

The question can be interpreted as

Y= k/x^2.......eqn(1)

Where k= constant if proportionality

y = 1/8 when x = 1,

Substitute, we have

1/8= k/(1)^2

1/8= 1/k

Cross multiply

K= 1/8

find y when x = 5

From eqn(1)

Y= k/x^2

Y= (1/8)/(5)^2

Y=1/8 ×25

Y= 25/8

If Mai jumped 14 inches, how many inches did Xeno reach? (You can use a tape diagram or hanger diagram to help solve this problem). ***EXPLAIN how you found your answer below:

Answers

Answer:

Xeno jumped 1 2/3 in

Step-by-step explanation:

if Mai jumped 3 times higher than Priya dividing Mai's 14 by 3 would get Priya's height. Then by subtracting 3 from Priya's height, which is 4 2/3, you get Xeno's height which is 1 2/3 in

Answer:

maybe 6 1/2

Step-by-step explanation:

5 square inches is the area of triangle PQR in square inches.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given a triangle PQR.

We need to find the measurement is closest to the area of triangle PQR in square inches.

The PR is 2.6 inches in height and RQ is 4.1 inches.

We know that area of triangle is 1/2 times base and height.

By using ruler we calculated the height of triangle is 2.6 inches and base is 4.1 inches

The formula for area is

Area=1/2(Base×Height)

Plug in the values of base and height

=1/2(4.1×2.6)

=1/2(10.66)

=5.33

=5 square inches

Hence, 5 square inches is the area of triangle PQR in square inches.
