Molly's snowboard is 150 cm long; Pete's is 16% longer. How long is Pete's snowboard?​
Amiraneli [1.4K]

Answer:

174 centimeters

Step-by-step explanation:

You take 150 and divide it by 10 which gives you 15. since you divide it by 10 and it gives you 15 that means ten percent is 15 centimeters. since we need to find out what the 16 percent is we take the 15 and divide that by 10 which gives us 1.5. That tells us every 1 percent, is 1.5 centimeters. you take the 150 and add 15 and that gives you 165. We have already done 10 percent out of the 16 percent . Now we have to figure out how much the rest of the 6 percent is so we take the 1.5 and multiply it with the 6 and we get a 9. That covers up for the rest of the 6 percent out of the 16 percent. Now we add 165 with 9 to get our answer of 174 centimeters.

When amy exercises in her fitness for 1 hour she burns a total of 475calories if she burns 9 calories a minute jogging on the tr
Alex73 [517]

Answer:

  26 minutes on the bicycle

Step-by-step explanation:

Let t and b represent the number of minutes on the treadmill and bicycle, respectively. The problem statement tells us two ways to relate these values.

  t + b = 60 . . . . . Amy exercises a total of 60 minutes (1 hour)

  9t +6.5b = 475 . . . . . she burns a total of 475 calories

Since we want to find the value of "b", we can use the first equation to write an expression that will substitute for t.

  t = 60 -b

  9(60 -b) +6.5b = 475

  540 -2.5b = 475 . . . . . . simpify

  -2.5b = -65 . . . . . . . . . . subtract 540

  b = 26 . . . . . . . . . . . . . . . divide by -2.5 (equivalently, multiply by -2/5)

Amy spends 26 minutes exercising on the bicycle.
