Sonya had 30 minutes to do a three-problem quiz. She spent 10 9/10 minutes on question A and 6 3/5 minutes on question B. How much time did she have left for question C?
Answer:
time left for question C = 12 1/2
Step-by-step explanation:
Total time required for the three quiz= 30 minutes
time spent on question A= 10 9/10 minutes
Time spent on question b= 6 3/5 minutes
Time spent on Question c= Total time required for the three quiz -( time spent on question A+Time spent on question b)
30 - ( 10 9/10 + 6 3/5)
30 -16 (9+ 6/10)
30- 16 15/10( 15/10 = 1 5/10)
30 - 16 + 1 5/10
30 - 17 5/10
From 30, we remove 1 whole number to subtract the fraction from the other number so we have
29 - 17 ( 1 -5/10)
=12 5/10 = 12 1/2

PLEASE HURRY-When Melissa is playing soccer she makes 2 goals out of every 12 shots on goal. How many times would you expect her to make the goal if she took 144 shots on goal?
Answer: 24 goals
Step-by-step explanation:
Melissa makes 2 goals out of every 12 shots on goal.
This means that the amount of shots needed to score a goal for her is:
= Number of shots / Number of goals
= 12 / 2
= 6 shots
She scores a goal every 6 shots.
If she makes 144 shots therefore, she will score:
= Number of shots / Number of shots needed per goal
= 144 / 6
= 24 goals

what is the value of c?
Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.
W-20.5=8 please help me
This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.
We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.
w-20.5+20.5=8+20.5
w=28.5

A total of 714 tickets were sold for the school play. They were either adult tickets or student tickets. There were 64 more
student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
714 is the total number that is sold, if there is 64 more tickets sold for students then adults, then do 714 divided by 2 and add 32 to get the number for students, and for adults do 714 divided by 2 and subtract by 32. so, like this 714/2+32=389 tickets for students and 714/2-32=325 for adults. Hope this helps
Answer:
The adult tickets total were 293
Step-by-step explanation:
714 divided by 2 ( because there is only 2 types of tickets ) and 714 divided by 2 equals 357 ad because the student tickets sold better 357 minus 64 = 293 and you prove that by multyplying 357 x 2 = 714

A town has a population of 18000 and grows at 2% every year. To the nearest tenth of a year, how long will it be until the population will reach 26700?
^^
Answer:
19.9
Step-by-step explanation:
we can write the following equation
18000(1.02)^n
where n is the number of years
so we have
26700=18000(1.02)^n
solve for n
1.483=1.02^n
use logs to solve for n
n=19.9

quick please I have only a few min left
Step-by-step explanation:
first box on the left
r=4
d=8
circumference= 2π*4= 8π
area = π*4*4= 16π
Second box on the left
d=6
r= 3
circumference= 2π*3= 6π
area =π*3*3= 9π
third box on the left
A=36π
A=36πarea= π*r*r
A=36πarea= π*r*rr= 6
A=36πarea= π*r*rr= 6d=12
A=36πarea= π*r*rr= 6d=12circumference= 2π*6= 12 π
the last box
C=18π
C=18πC= 2π*r
