Answer 1

Given:

A figure of a right triangle with perpendicular 500 m and hypotenuse x.

To find:

The value of x.

Solution:

If a transversal line intersect two parallel lines, then alternate interior angles are congruent.

Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.

In a right angle triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

In the given triangle,

[tex]\sin 40^\circ =\dfrac{500}{x}[/tex]

[tex]x=\dfrac{500}{\sin 40^\circ }[/tex]

[tex]x=\dfrac{500}{0.6427876}[/tex]

[tex]x=777.8619[/tex]

Round the value to the nearest tenth.

[tex]x\approx 777.9[/tex]

Therefore, the value of x is 777.9 m.

Suppose each license plate in a certain state has one digit, followed by four letters, followed by one digit. The letters F, O, S, and X and the digit 0 are not
used. So, there are 22 letters and 9 digits that are used. Assume that the letters and digits can be repeated. How many license plates can be generated using
this format?

Answers

Each digit can be 1 of 9 numbers.

Each letter can be 1 of 22 letters.

To find total combinations, Multiply each number of choices by each number of choices.

9 x 22 x 22 x 22 x 22 x 9 = 18,974,736 total combinations

Option C would be correct!

Step-by-step explanation:

For Option A 8(2r) would be 16r not 10r

For Option B 6r + 3 would be 6r + 3 not 9r

For Option C 9(3r - 4) would be 27r - 36, and that indeed is the answer

For Option D r + r + r + r + r would be 5r not r⁵

I really need help!!!
The kitchen, dining room, and living room of a house will be painted, each with a different color. There are 7 colors to choose from. This means that there are _[blank]_ color arrangements possible.

What number best completes the sentence?

Enter your answer as a number, like this: 42

Answers

Answer:

Step-by-step explanation:

First, you put all of the possiblities for the kitchen.

Then, you multiply 7 by each room which would be 3 so,

3 * 7 = 21

So, 21 is probably your answer.

Lastly, have a great day!

There are 210 color arrangements possible

The number of rooms (r) in the house is given as:

[tex]r = 3[/tex] ---- i.e. the kitchen, dining room, and living room

The number of available colors (n) to select from is also given as:

[tex]n = 7[/tex]

The possible color arrangement is calculated using the following permutation formula

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

So, we have:

[tex]^7P_3 = \frac{7!}{(7 - 3)!}[/tex]

Remove bracket

[tex]^7P_3 = \frac{7!}{4!}[/tex]

Expand the numerator

[tex]^7P_3 = \frac{7 \times 6 \times 5 \times 4!}{4!}[/tex]

[tex]^7P_3 = 7 \times 6 \times 5[/tex]

[tex]^7P_3 = 210[/tex]

Hence, there are 210 color arrangements possible

find the value of x

1) 62°

2) 90°

3) 180°

4) 28°

Answers

4) 28 is the answer because it is a 90 degree angle, so you got half of it and all you do it subtract 90-62=28

Answer:

Hello! answer: 28

Step-by-step explanation:

This is a complementary angle! So it will add up to 90 degrees so all we have to do is 90 - 62 so 90 - 62 = 28 so 28 is our answer!

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?

Answers

Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Albert's rectangular garden is 6ft by 3ft. He wants to lengthen both dimensions by the same number of feet so that the new area will be 40 square feet. What will be the new dimensions?

Answers

Answer:

8 and 5

Step-by-step explanation:

Let the number of feet added = x

(x + 6) ( x + 3) = 40 Remove the brackets

x^2 + 6x + 3x + 18 = 40 Combine like terms on the left

x^2 + 9x + 18 = 40 Subtract 18 from both sides

-18 -18

x^2 + 9x = 22 Subtract 22 from both sides

x^2 + 9x - 22 = 0

This quadratic factors

(x + 11)(x - 2)

x + 11 = 0

x = - 11 which makes not sense.

x - 2 = 0

x = 2

The answer is x = 2
