Answers

Answer 1

Answer:

sqrt(29)

Step-by-step explanation:

We can find MN using the Pythagorean theorem

The height is 2 and the length is 5

a^2 + b^2 = c^2

2^2 + 5^2 = MN ^2

4 + 25 = MN^2

29 = MN ^2

taking the square root of each side

sqrt(29) = MN

HELP MEE!!!|||||||||Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to
the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank) (4 points)

Answers

Answer: There are several information's of immense importance already given in the question. Let us write them down first.

Diameter of the cylinder = 6 inches

Then

Radius of the cylinder = 3 inches.

Height of the cylinder = 3 * radius

= 3 * 3

= 9 inches

Volume of the cylinder = (pi) * (Radius)^2 * Height

= 3.14 * (3)^2 * 9

= 3.14 * 9 * 9

= 254.34 cubic inches

Find the distance between the points (4,3) and ( 0,6)

Answers

Answer:

Step-by-step explanation:

The distance between the points (4,3) and ( 0,6) is; d = 5

The formula for distance between two coordinates is given as;

d = √((y2 - y1)² + (x2 - x1)²)

We are given the coordinates;

(4,3) and (0,6)

Thus;

x1 = 4

x2 = 0

y1 = 3

y2 = 6

Thus;

d = √((6 - 3)² + (0 - 4)²)

d = √(3² + 4²)

d = √25

d = 5

Solve for m:
8(m + 2) = 3(12 - 4m)

Answers

Answer:

m=1

Step-by-step explanation:

step 1: 8(m + 2) = 3(12 - 4m) remove the parentheses

step 2: 8 m + 2 = 3 12 - 4m move the terms

step 3: 8m+ 12m= 36 - 16 collect like terms and calulate

step 4: 20m=20 divide both sides

solution: m=1

Answer:

m = 1

Step-by-step explanation:

To solve for m, we will have to get m by itself on one side, with some value on the other side.

8(m + 2) = 3(12 - 4m)

Distribute the 8 on the left side and the 3 on the right side.

8m + 16 = 36 - 12m

Add 12m to both sides.

20m + 16 = 36

Subtract 16 from both sides.

20m = 20

Divide both sides by 20.

m = 1

So now we have the answer m = 1.

A tree 24 feet tall casts a shadow 12 feet long. Brad is 6 feet tall. How long is Brad's shadow?

Answers

Answer:

Brad's shadow is 3 feet long

Step-by-step explanation:

If a tree is 24 feet tall, and casts a shadow 12 feet long, The we know the shadows will be half as big as the main object.

Because Brad is 6ft tall, His shadow will be half of his hight (3ft long)

The slope of the tree to shadow is equal to the slope of Brad to shadow. The Brad's shadow is 3 ft long.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.

A tree 24 feet tall casts a shadow 12 feet long.

Brad is 6 feet tall.

The slope of the tree to shadow is equal to the slope of Brad to shadow (x). Then we have

[tex]\rm \dfrac{x}{6} = \dfrac{12}{24}\\\\x \ = \dfrac{6*12}{24}\\\\x \ = 3[/tex]
