Answer:

Step-by-step explanation:

Remark

x is opposite the 90 degree angle. It is the hypotenuse. 15 is opposite the 66 degree angle. It is the side opposite.The side opposite and the hypotenuse define the sin(theta).

Formula

sin(theta) = side opposite / hypotenuse

Givens

Theta = 66 degrees

Hypotenuse = x

Side Opposite = 15

Solution

Sin(theta) = 15 / x         Multiply both sides by xx*sin(theta) = 15           Divide by Sin(theta)x = 15/sin(theta)x = 15 / sin(66)sin(66) = 0.9135x = 15/ 0.9135x = 16.42

A box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys. If you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.​

Answers

Answer: 3/95

Total Number of jerseys:

10+6+4=20

Odds of first jersey being medium:

4/20

Odds of second jersey being medium

3/19

(4/20)*(3/19)=12/380=

6/190=3/95

The probability that you randomly grab 2 medium jerseys is 3.15%.

Since a box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys, to determine, if you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys, the following calculation must be performed:

10 + 6 + 4 = 20 4/20 x 3/19 = X 0.0315 = X 0.0315 x 100 = 3.15%

Therefore, the probability that you randomly grab 2 medium jerseys is 3.15%.

Answers

Answer:

the answer is $65

Step-by-step explanation:

Answer:

$70

Step-by-step explanation:

Explanation

If we reverse it we can break it down easier: We start at $935

15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165

935-165=770

770 is the amount left without the money he has earned so the total base.

770/11=70

Checking answer

Let's rebuild it to test if it is correct...

$70 for each tv * 11 tv's = $770 or the base price of the tv's

$15 for all the warranties

$15*11=165

165+770=935

So the answer is 70$

Hopefully, this helped.

Answers

Answer:

8(a+2c)

Step-by-step explanation:

Hey There!

If you didn't know the greatest common factor (GFC) is the largest number that all of the numbers can be divided by and have a whole number as the outcome

For this expression the GFC is 8 because both of the terms can be divided by 8 and have a whole number as a result

8a/8=a

16c/8=2c

So the factored version of 8a+16c is 8(a+2c)

x = 14

Step-by-step explanation:

Figure A to Figure B = 1:3.5 = 1/3.5

Thus:

4/x = 1/3.5

Cross multiply

x = 14

Jack and Jill are 432 meters apart, but are walking towards each other. Joe walks at a pace of 2 meters per second, while Jill walks at a pace of 3 meters per second. After how many seconds will they meet up?

Answers

Answer:

86.4 seconds.

Step-by-step explanation:

Given that Jack and Jill are 432 meters apart, but are walking towards each other, and Joe walks at a pace of 2 meters per second, while Jill walks at a pace of 3 meters per second, to determine after how many seconds will they meet up, the following calculation must be performed:

432 / (3 + 2) = X

432/5 = X

86.4 = X

So, Jack and Jill will meet after 86.4 seconds.

I need help with 20!

Answers

Answer:

C

Step-by-step explanation:

4 boxes: $3.79 is  $0.9475 or $0.95

a. 6 boxes: $5.79 is $0.95833333333 or $0.96

b. 2 boxes: $1.96 is 0.98

c. 3 boxes: $2.79 is $0.93

d. 1  box: $0.97 os $0.97

0.98 > 0.97 > 0.96 > 0.95 > 0.93

Answer:

3rd answer choice: 3 for $2.79

Step-by-step explanation:

“You bought 4 boxes of facial tissues for $3.79.Which is a better buy than the one you bought?”

First, find the individual box cost for the given amount in the question. Divide the total cost ($3.79) with the amount of boxes (4) to get the individual amount:

$3.79/4 = ~0.9475, or $0.95

The first answer choice looks like 6 boxes for $5.75. Divide 6 from $5.75:

$5.75/6 = ~0.9583, or $0.96 (1 cent more)

The second answer choice looks like 2 boxes for $1.96. Divide 2 from $1.96:

$1.96/2 = 0.98, or $0.98 (3 cent more)

The third answer choice looks like 3 boxes for $2.79. Divide 3 from $2.79:

$2.79/3 = 0.93, or $0.93 (2 cents less).

The fourth answer choice looks like 1 for $0.97.

$0.97 (2 cents more)

~

In this case, the cheapest one by individual costs is the 3rd answer choice, as it is the cheapest by individual boxes.

discount % = 33.33%--------------------------------

Step-by-step explanation:

original price = $4.50

sale price = $3

discount price = $4.50 - $3

= $1.50

discount = discount percent × original price ÷ 100

$1.50 = discount percent × $4.50 ÷ 100

discount percent = $1.50 × 100 ÷ $4.50
