A line segment has an endpoint at (-4,8) and a midpoint

Mathematics

grin007 [14]2 years ago
7 0

Answer:

The coordinates of the midpoints are the average coordinates of the endpoints. Suppose (x1,y1) and (x2,y2) are the endpoints and (xm,ym) is the midpoint, we have xm=x1+x22 and ym=y1+y22 . Therefore, 2xm=x1+x2 and 2ym=y1+y2 . From there, we should be able to figure the other endpoint out given an endpoint and the midpoint.

Express the ratio in the simplest form. 20 gallons to 0.75 gallons
expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

20:0.75

This is the same as

20: \frac{3}{4}

We multiply each term in the ratio by 4 to obtain;

20 \times 4:0.75 \times 4

This gives us,

80:3

Darya [45]

Answer:

I dont know But maybe the answer is No

Step-by-step explanation:

0.3 is 30% and if 1/10 is 10% then 2/20 must be 10% because 5% is 1/20

so maybe 3/20 is only 15%

I hope this helps :)

A 40-foot ladder is leaning against a building and forms a 29.32° angle with the ground. how far away from the building is the b
zaharov [31]

The distance between the building and the ladder is 34.876 foot.

<h3>What is a Right Triangle?</h3>

A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.

The ladder forms a right triangle with the building and the ground,

The length of the triangle is 40 foot

The angle made by the ladder is 29.32 degree

By using Trigonometric Ratios

cos 29.32 = Base /  Hypotenuse

cos 29.32 = Base / 40

0.8718 × 40 = Base

Base = 34.876 foot

Base is the distance between the building and the ladder.

Base of the ladder = 34.876 foot
