what does QR=?

Answers

Answer:

PQ=12

QR= 8

Hope it helps.

Answer: PQ = 12

QR = 8

Step-by-step explanation:

3x + 6 + 2x+4 = 20

5x = 20- 10

so, x = 2

so

PQ = 3x + 6 = 3*2+6 = 6+6 = 12

QR = 2x+4 = 2*2+4 = 4+4 = 8

case high school sold 120 tickets to the school play and took in $195 from ticket sales. if student tickets were $1 and adult tickets were $2, how many of each kind did they sell?

Answers

Answer: student = 45 ticket sold, adult = 75 ticket sold.

Explanation:

Assume that all the ticket sold were adult ticket:

120 x 2$ = 240$

Then:

240$ - 195$ = 45$

Calculate the difference between student ticket and adult ticket:

2$ - 1$ = 1$

Find the student ticket:

45$/1$ = 45

45 ticket sold is the student ticket.

Find adult ticket sold:

120 - 45 = 75

75 ticket sold is the adult ticket.

Check:

(45 x 1) + (75 x 2) = 195
45 + 150 = 195
195 = 195

36 clicks every 5 seconds

Step-by-step explanation:

First you divide the number of clicks by seconds.

36÷5=7.2

26÷3=8.6

Now you know how much clicks the bots do in 1 second

Bot#3= 7.2

Bot#4= 8.6

Now multiply by 10.

Bot#3= 72

Bot#4= 86

Bot#4 does more clicks in 10 seconds.

A jar contains 30 red marbles, 50 green marbles, and 20 blue marbles. What is the probability of getting a
marble that is not red when drawing one at random?

Answers

Answer:

P(not red marble)=8/11

Step-by-step explanation:

sample space is 110

subtract the red (30)

110-30=80

80/110=8/11

gg ez

There are a total of 100 marbles (30+20+50).
Of that 100, 70 are not red (50 green + 20 blue).

This means you have a 70/100 chance of pulling something that’s not red.

70/100 reduces down to 7/10 or 70%.
