Mathematics
1 answer:
maw [93]3 years ago
5 0

1) Answer: 113

3^3 + 2[64 - (3x7)]

27 + 2[64 - (3x7)]

27 + 2[64 - 21]

27 + 2[43]

27 + 86

= 113

3) Answer: (-1, 11)

Since the problem said that it was 11 points across the y-axis, you just have to replace the -12 with 11 because -12 is the y-value.

4) 5.5 quarts = 11 pints

1 quart is equal to 2 pints, so just double the amount of quarts.

5)  120 minutes (or 2 hours)

Set up a proportion and solve for the missing value. (24/x = 6/30)

6) 5 and 8

5 x 8 = 40

5 + 8 = 13

8) -8.95

1.3 + (-6) + (-4.25)

1.3 - 6 - 4.25

-4.7 - 4.25

= -8.95

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.
