Answer:

13

Step-by-step explanation:

12 - 0 = 12

0 - 5 = -5 which is same as 5 here

12^2 + 5^2 = 144 + 25 = 169

sqrt 169 = 13

<h3>Answer: 13</h3>

==========================================================

Explanation:

We have the two points (x_1,y_1) = (0,0) and (x_2,y_2) = (12,-5)

Apply the distance formula to them.

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\&#10;d = \sqrt{(0-12)^2 + (0-(-5))^2}\\\\&#10;d = \sqrt{(0-12)^2 + (0+5)^2}\\\\&#10;d = \sqrt{(-12)^2 + (5)^2}\\\\&#10;d = \sqrt{144 + 25}\\\\&#10;d = \sqrt{169}\\\\&#10;d = 13\\\\

The distance from Sara's house to the school is exactly 13 km.

An alternative is to use the pythagorean theorem. The distance formula is effectively based on this theorem.

To check the answer, you can use a tool like GeoGebra to plot the two points given. Then draw a segment between them. It should show "13" as the segment length. That app also has a "distance" tool as an alternative. So there are a few ways to get the answer, and to check it as well.

A bag of potatoes weights 30 lb. If 74% of a potato is water, how many pounds of water are there in the bag?
Nadya [2.5K]

Answer: There are 22.2 pounds of water in the bag.

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).

Mathematically speaking:

30 x (74/100) = 30 x 0.74 =22.2 pounds

There are 22.2 pounds of water in the bag.

When paid flat a round parachute has a diameter of 8 meters. What is the parachute’s circumference
mariarad [96]

Answer:

25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

c=2\pi r (1)

where:

\pi\sim 3.14

r is the radius of the circle

In this problem, the parachute has a diameter of 8 meters:

d = 8 m

The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

r=\frac{d}{2}=\frac{8}{2}=4 m

And therefore, by applying eq.(1) we can find the circumference of the circle:

c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m
