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?
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

Use the information below to respond to numbers 5,6,7 and 8.
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:
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
Answer 2-5
Help please
Please help me find the slope!!!!!
Answer:
Slope = 3/2 or [tex]1\frac{1}{2}[/tex] or 1.5
Step-by-step explanation:
Points on graph: (0, 0) and (2, 3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3-0)/(2-0)
m= 3/2

x + 1/4 = 5/6
solve the equation for x
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
If the length of an arc of measure 55 degrees is 3.87 inches find the circumference of the circle
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

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

50 hundredths = ______ thousandths equals?
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
