Answer:
Hence, a carpenter can paint a maximum of 7 chairs.
Hence, option A is correct.
Step-by-step explanation:
A carpenter has less than 120 min. to spend painting furniture each day.
Today, he has spent 30.5 min. painting a desk.
Now he will paint x chairs, each of which takes 12.5 min.
i.e. he will take a total of 12.5x minutes in painting 'x' chairs.
Also total time spent on painting furniture each day will be equal to time spent on painting a desk and all of the chairs.
Hence,
30.5+12.5x<120 (since the total time he spends on painting is less than 120 mins.)
⇒ 12.5 x<120-30.5
⇒ 12.5 x<89.5
⇒ x<7.16 ( on dividing both side of the inequality with 12.5)
Hence, a carpenter can paint a maximum of 7 chairs.
Answer:
Blue Ballon = 16
Yellow Ballon = 23
Green Ballon = 26
Red Ballon = 32
Total puffs = 1000
23y + 16(2y) + 32y + 26(y/2) = 1000
23y + 32y + 32y + 13y = 1000
100y = 1000
y = 1000/10
y = 10

filled 10 yellow balloons.
11/30 bags of mulch is needed.
<u>Step-by-step explanation:</u>
We have to find the number of bags of mulch.
7 (1/2) sq. yards need 2(3/4) bags of mulch.
So one sq. yd need 2(3/4) / 7(1/2)
We have to change the mixed fraction into improper fraction and then dividing them we will get the answer.
2(3/4) = ((2×4)+ 3)/4 = (8+ 3)/4 = 11/4
7(1/2) = ((7×2)+1)/2 = (14+1)/2 = 15/2
11/4 ÷ 15/2
It change into multiplication as,
11/4 × 2/15 = 11/30 bags of mulch is needed.

Answer:
Least number is 60.
Step-by-step explanation:
Let the number of CDs has Jo be represented by x + 10. Where x = 0, 1, 2, 3....
Then, since Ken has twice as many CDs as Jo, the number of CDs that Ken has can be expressed as;
2(x + 10) = 2x + 20
Maisie has three times as many CDs as Ken, then the number of CDs that Maisie has can be expressed as;
3(2x + 20) = 6x + 60
Thus to determine the least number of CDs that Maisie can have, let x = 0.
3(2x + 20) = 6x + 60
= 6(0) + 60
= 60
Therefore, the least number of CDs that Maisie can have is 60.
