Answer:
CB = 20 or D
Step-by-step explanation:
Remark
You have a proportion. A proportion consists of 2 equal ratios. Three parts of the Proportion of 4 much be known. Then you can solve for the 4th.
Formula
Large vertical / Small Vertical = large horizontal / Small horizonal. Notice how Large goes on top of the ratios and small on the bottom.
Givens
Large Vertical: 8 feet
Small Vertical: 5 feet
Large horizontal: CA + 12.5 feet
Small Horizontal: 12.5
Solution
8/5 = (CA + 12.5) / 12.5 Cross Multiply
5(CA + 12,5) = 8 * 12.5 Remove the Brackets
5CA + 62.6 = 100 Subtract 62.5 from both sides.
5CA = 37.5 Divide by 5
CA = 7.5
CB = CA + 12.5
CB = 7.5 + 12.5
CB = 20
Answer
D
12 is the answer all u have to do is divide 2
Step-by-step explanation: In this equation, it's important to understand that the number 5 is the coefficient on the variable M. This just means that -5 "times" M equals -40. So, whenever you see a number next to a variable, it means multiplication.
If we were to solve, we would just divide both sides of the equation by 5. On the left the 5's cancel and on the right, -40 divided by 5 is -8.
Speed: 30mi/sec
Seconds in one minute: 60
Seconds in 6 minute: 60 x 6 = 360 seconds
take the speed of 30miles / seconds and times it with 360, and you get a total distant traveled: 10800 miles
