Can i get some plzz i really need to finish this

9. a) 8.25

10. c) 180

9) 8.25 - Option A

10) 180 - Option C

Step-by-step explanation:

9) The square root of 68: To solve this you need to look for the closest square root before and after 68. This is 64 which is 8 and 81 which is 9.

Then you calculate how far apart they are: 68 - 64 = 4 and 81 - 64 = 17

Finally, since 68 is closer to 64 you approximate which gives you 8.25

10) Least common multiple or LCM is the smallest number that can be divided by all 3 numbers:

12 - 1, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180,

15 - 1, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180

18 - 1, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180

So since 180 is the smallest number that can be divide by all three numbers that is the least common multiple.

7

step-by-step explanation:

the answer would be 7

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
