Answer:
Step-by-step explanation:
Bob ran the first part of a 12 km race at a speed of 8 kmph. He ran the second part of the
race at 10 kmph. If his total time for the entire race was 1.74 hours, how far did he run in
the first part of the race?
First part :
Total Distance = 12 km
First part Speed = 8kmph
Let distance covered on first part = x
Second part speed = 10kmhr
(8*x)
You would use PEMDAS Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. So first we would use P in PEMDAS witch is 15+9=24
Then you would use Multiplication 24 x 28 = 672
So your answer would be 672
Answer:
105 degrees
Step-by-step explanation:
You first add 5 and 7 which gives you 12. Then, since two supplementary angles add up to 180, you divide 180 by 12 which gives you 15. Next, since 7 is the larger of the two, multiply 7 by 15 giving you 105. To check your work, subtract 105 from 180 giving you 75. Next, put this as a fraction- 75/105 and simplify giving you 5/7 which can also be written as 5:7.
