The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?

The measure of the larger angle is
°. what is the angle

Answers

Answer 1
First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x.

A. $212.50

B. $133.75

C. $116.25

D. $8.75

Answers

Answer:B: 133.75$

Step-by-step explanation:

35 + 40 + 50= 125$

The total sales tax is 7%

We can put this into decimal form 7/100= 0.07

Because we want to just add 7% of the value back on we can also add 1 to that number

1.07

125 x 1.07 = 133.75

Answer:

the answer is b

Step-by-step explanation:

because if you add 40 + 35 + 50= It would equal 125. Then you add it to 7% and theres your answer.

Twelve Friends go to a movie. Although, They Pay $124.32 for tickets and snacks. they share the cost equally. How much does each person pay? Explain how u got your answer. =)

Answers

Answer:

Answer vary :

each person pays $10.36.

Step-by-step explanation:

‘honestly in my opinion that’s the answer.

we’re trying to find how much each person payed so we have to start by dividing.

-124.32 divided by 12 = 10.36

to find out if it is correct we can multiply 10.36 by how many people are paying.

-10.36 times 12 = 124.32

after multiplying we get the cost of tickets and snacks wich makes it correct.

and that’s how I came to that solution.

124.32 decided by 4, is how you find the answer the answer

Given the equation of the graph, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).

What is the graph of the equation?

Given the equation y = -1/3x + 5

Using the slope intercept form; y = mx + b

Hence,

Slope m is -1/3

y-intercept = ( 0, 5 )

From the equation, y = -1/3x + 5

All lines can be graphed using two points, we select two x values and plug it into the equation; 0 and 3

For x = 0

y = -1/3x + 5 = -1/3(0) + 5 = 5

For x = 3

y = -1/3x + 5 = -1/3(3) + 5 = -(3/3) + 5 = -1+5 = 4

Hence, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).

Answer:y=4/3 as an improper fraction or 1 1/3 as a mixed number (decimal: 1.3333…). There are 1 1/3rd 3/4s in 1.

PREMISES

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 10 people took the trip. She was able to purchase coach tickets for ​$320 and first class tickets for ​$1290. She used her total budget for airfare for the​ trip, which was ​$9020. How many first class tickets did she​ buy? How many coach tickets did she​ buy?

Answers

1. Start with your known values for each type of seating, coach and first class.
2. One can guess and check for this, so for instance,
$1290 * 6 = $7740
and,
$320 * 4 = $1280
Finally, $7740 + $1280 = $9020
A quick note: Sarah probably purchased more first-class tickets than coach tickets because $1920 is a lot more than $320. Meeting her budget total would most likely mean more first-class seats

[tex]\sqrt{1600}[/tex]=40

pythagorean theorem: a^2 + b^2 = c^2

75^2 + 85^2 = c^2
5625 + 7225 = c^2
12850 = c^2

take the square root of both sides

c ≈ 113
