You could compare by simplifying 3/8. get the decimal by dividing 3 by 8 to get .375
Answer:
The answer is c. f(n)=4n+1
Step-by-step explanation:
In the function of the answers, n is the input and f(n) is the output. So the ordered pairs needs to be at the form (n,f(n))
Additionally, in the ordered pairs given in the question, the first term is the input and the second term is the output. For example in the ordered pair (1,5), 1 is the input and 5 is the output.
So, if we replace n by 1, f(n) needs to be 5. This condition is only satisfied on option c. That's is also prove for every ordered pair as:
For (1,5)
if n=1 then:
f(n)=(4*1)+1=5
For (2,9)
if n=2 then:
f(n)=(4*2)+1=9
For (3,13)
if n=3 then:
f(n)=(4*3)+1=13
For (4,17)
if n=4 then:
f(n)=(4*4)+1=17
Finally, the functions that best represents the rule that the calculator uses to display the outputs is f(n)=4n+1
Answer: Brandon is 24, Michael is 72.
Step-by-step explanation:
Let m represent Michael
Let b represent Brandon
Then,
m = 3b <-----------"Michael is 3 times as old as Brandon."
m - 18 = 9(b - 18) <-----------"18 years ago, Michael was 9 times as old as Brandon."
3b - 18 = 9b - 162
-18 = 6b - 162
144 = 6b
Michael is 3 times as old as Brandon. Also, 18 years ago, Brandon would have been 6 and Michael would have been 54 meaning Michael was 9 times as old as Brandon 18 years ago.
Answer:
A. Answer is 2263.
Checkpoint 1 is -86 Checkpoint 4 is 2177
Subtract -86 from 2177....2177-(-86)
=2263
2263 is how much higher checkpoint 1 (-86) is from checkpoint 4 (2177)
B. 239 FEET.
the altitude of the hill must be subtracted by the depth of the ckeckpoint(2)(-189)
therefore the altitude of the hill comes out to be 428-189=239feet.
therefore,the actual altitude of the hill is 239 feet.
The answer is sometimes true
