A rectangle is eight inch long and its diagonal is ten inches. What's the width of the rectangle?

Answers

Diagonal = $\sqrt{length^(2) + width^(2) }$

10 = $\sqrt{8^(2) + width^(2) }$

10 = $\sqrt{64 + width^(2) }$

100 = 64 + $width^(2)$

$width^(2)\n$ = 100 - 64

$width^(2)$ = 36

width = $√(36)$

width = 6 inches

Answer:

the answer is 6 inches

Step-by-step explanation:

To find the diagonal we use the Pythagorean Theorem:

l² + w² = d² where the is d hypotenuse

8² + w² = 10²

64 + w² = 100

w² = 100 - 64

w² = 36

w = √36

w = 6

therefore the width of the rectangle is 6 inches

Explain what the variable represent in an addition or subtraction expression.

Answers

A variable is just a letter that represents a number. It doesn't really matter what letter it is (unless the directions say so). Well its sort of hard to explain but I hoped this helped you out a bit. ^^''

What are three ways a rectangle and a square are alike

Answers

-- Each has 4 sides.
-- Opposite sides of each are parallel.
-- Opposite sides of each have equal length.
-- Interior angles of each sum to 360 degrees.
-- Each is a special case of parallelogram.
-- Each has all interior angles equal.
-- Area of either one is (length) x (width).

Rectangles and squares are alike in that both have two pairs of parallel sides and four right angles. They are different because a square must have four equal sides lengths and a rectangle has two pairs of equal side lengths.

HEELP please i dont under stand

Answers

the answer is A 3/10 because there is 3 blue marbles and all together there is 10

b. 2/9
You add up how many marbles there are. in this case there is 10. 3 out of those are blue. so you start out with the probability being 3/10. you take 1 marble out, making the total 9 now. now look at the color. you started with 2 red, 3 blue, and 5 yellow. you pulled out a blue, didnt put it back, so now there are 2 blue marbles left out of 9 marbles. there probability is now 2/9. hope i helped you.

A row of tiny red beads is placed at the beginning and at the end of a 20-centimeter bookmarkA row of the same beads is also placed every 4 millimeters along the bookmark
How many rows of the beads are used on the bookmark?
Enter your answer in the box

Answers

Answer:

There are 50 beads on the bookmark.

Step-by-step explanation:

To know the number of rows of the beads are used on the bookmark, we just need to divide.

Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.

We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.

Then, the division is

$(200mm)/(4mm) =50$

Therefore, there are 50 beads on the bookmark.
