Samriti traveled 7/12 of the distance to her cousin's house before taking a break. which fraction represents the remainder of her trip? if her total trip is 240 miles, how far does she still need to travel?

Answers

If Samriti travels 7/12 of her trip she has 5/12 remaining.
Her total trip will be 12/12 therefore if you find what you need to add to 7 to make five we find the remainder of her journey. 12-7=5

If her total trip is 240 miles and we need to find 5/12 of it.
We first divide it by 12: 240/12= 20
This gives us 1/12 of her trip, 20=1/12
We now need to multiply 20 by 5 so get 5/12 of her trip:
5 x 20 =100
Therefore, 100 is the same as 5/12, which is the remainder of her journey.

Use the graph of the exponential growth function f(x) = a(2x) to determine which statement is true. f(0) = 2 when a = . f(0) = 3 when a = 3. f(1) = 9 when a = 9.

Answers

Answer:

Step-by-step explanation:

f(0)=3 when a =3

hope it helps

If the function is exponential, then (2x) is the exponent.

f(x) = a^(2x)

Please help me answer this ASAP! The two-way table shows the number of ninth and tenth graders who prefer going to sporting events or going to the movies.Among tenth graders, what is the relative frequency of preferring sporting events? Express your answer as a decimal, and round to the nearest hundredth if necessary

Answers

Answer

0.43

Explanation

Remember that $RelativeFrecuency=(Frecuency)/(SumOfAllFrecuencies)$

Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so $Frecuency=6$ . Now, the sum of all frequencies will be the sum of all the 10th graders, so $SumOfAllFrecuencies=6+8=14$ . Let's replace the values:
