159189y1794Is This Relation A Function?yesno

Answers

Answer 1
This relation is NOT a function.
An input cannot have more than one output, and in this case, 9 has both outputs 9 and 3.
Therefore it is not a function
Answer 2
The relation is not a function. This is because there is a domain value that leads to two range values. X=9 leads to y=9 and y=3 or (9, 9) and (9, 3). Therefore, by definition, this relation is not a function because every range value must be assigned a unique domain value. In other words, x cannot “cheat” and can only have one y “partner.”

If the length of an arc of measure 55 degrees is 3.87 inches find the circumference of the circle

Answers

Answer:

25.33 is the circumference of the circle

Step-by-step explanation:

Here, given the measure of the arc, we want to get the circumference of the circle

mathematically, the length of an arc can be calculated using the formula;

theta/360 * 2 * pi* r

where 2 * pi * r = circumference of the circle

theta is the angle subtended at the center which is 55 degrees in this case

Thus, we have ;

55/360 * 2 * pi * r = 3.87

2 * pi * r = (3.87 * 360)/55

2 * pi * r = 25.33 inches

Answer: x - 30 = 10

Step-by-step explanation:

x - 30 = 10

x = 30 + 10

x= 40

x + 1/4 = 5/6
solve the equation for x

Answers

Answer:

x =7/12

Step-by-step explanation:

x + 1/4 = 5/6

start subtract 1/4 from both sides of the equation which will move the -1/4 to the other side to get X by itself

x=5/6 - 1/4

find common denominator, which is 12

x=10/12 - 3/12

solve by subtacting

x=7/12

The answer is x=7/12!!

Jasmine paid $380 for a playstation 5, originally priced at $500. What percent discount did Jasmine get?

Answers

She got it for 24% off

$500 - 24% = $380

Answer: 24% discount

If 500 = 100%
Then 380 = ?

Cross multiply 380 x 100 = 38000
Divide 38000 by 500 = 76
Subtract 76 from 100 = 24

Celeste was selling meal tickets for the holiday program at her school. The cost of a dinner ticket is
$10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold;
however, she remembered that she was given 100 tickets and she collected $900.
The system of equations shown can be used to represent this situation:
S x + y = 100
(10x + 6y=900
5. What does the variable x represent in the system of equations? *
1 point
O A. The number of dinner tickets sold.
O B. The number of dessert tickets sold.
O C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets.
O Other:

Answers

X is next to the number 10, so x would be the number of dinner tickets sold.

Rewrite x + y = 100 to x = 100-y

Now replace that in the 2nd equation:

10(100-y) + 6y = 900

Simplify:

1000 -10y + 6y = 900

Combine like terms:

1000 -4y = 900

Subtract 1000 from both sides

-4y = -100

Divide both sides by-4

Y = 25

Replace y in the first equation and solve for x

X + 25 = 100

X = 75

A) 75 dinner tickets were sold

B) 25 dessert tickets were sold

C) 75 x 10 = $750

D) 25 x 6 = $150

50 hundredths = ______ thousandths equals?

Answers

Answer:

50/100 = 500/1000 or alternatively .50 = .500

Answer:

500

Step-by-step explanation:

50 hundredths written in standard form is 0.50 .

**Adding zeroes to the end of a decimal does not change the value of the number.

1 hundredth = 0.01

1 thousandth = 0.001

So, if there are 50 hundredths, how many thousandths would there be?

The difference between hundredths and thousandths are the placement of the decimal point and how many decimal places there are after it. Hundredths have 2, while thousandths have 3.

Back to the example, 1 hundredth = 10 thousandths:

0.01 = 0.010

If there are 50 hundredths, that would mean that there are 10 times more thousandths in the same number.

0.50 = 0.500

50 hundredths = 500 thousandths

2.) is the answer to you question

Dots sells T-shirts ($5) and shorts ($8). In April, total sales were $560. People bought 4 times as many T-shirts as shorts.

Answers

Answer:

Number of T-shirts sold = 80 and number of shorts sold = 20

Step-by-step explanation:

This question is incomplete. If we have to calculate the number of shirts and T-shirts sold by Dots then we will calculate this question as below.

Let the number of shorts sold = s

And the number of T-shirts sold = T

Dots sells T-shirts at $5 and shots at $8 in April.

Equation for this situation will be,

5T + 8s = 560 -----(1)

Number of T-shirts sold are 4 times the shorts,

T = 4s ----- (2)

By substituting the value of T from equation (2) in equation (1),

5(4s) + 8s = 560

20s + 8s = 560

28s = 560

s = 20

From equation (2),

T = 4(20)

T = 80

Number of T-shirts sold = 80 and number of shorts sold = 20

Set up and solve a proportion: On average, I can answer 14 out of 21 questions correctly in a trivia game. Assuming
this situation is proportional, how many MORE questions am I likely to get correct if there are 30 questions in all?

Answers

Answer:

20

Step-by-step explanation:

Since this is a ratio problem we first plug in all that we know

14:x

21:30

Now we find a way to get from 21 to 30

The ratio 14:21 can be simplified if we divide each by 7 give us 2:3

Now we plug the new ratio in

2:x

3:30

We get from 3 to 30 by multiplying by 10 so we also multiply 2 by 10 and we get 20
