Answer:
- C for question 1
- A for question 2
Step-by-step explanation:
First Question
What you need to do here is pick an answer that will result in a decrease. If you have something like 1.3 * e ^ (0.038 * t), what will happen when t = 20
P = 1.3 * e^(0.038*20) = 1.3*e^0.76 = 2.77 which is getting bigger not smaller.
So what you want is something like 1.3 * e^-0.76 = 0.67
So which question is configured that way?
It's either C or D. but which one? It cannot be D. 0.38 is far too big: it does not represent 3.8%
C does represent 3.8% as a decimal. It is the correct answer.
Answer: C
Second Question
Every time she sells a ticket, the total that she gets is 4 more than what she had before.
The variation is a direct one. It is y = k*x. But what is k? Is it 4 or is it 1/4?
Read the first sentence above. She gets 4 dollars more, not 1/4 of a dollar.
C and D are both wrong because those equations think she is getting 1/4 more.
B is wrong because it says that the relationship is inverse. It is not. It is direct.
The answer is A
Answer:
252 plants
Step-by-step explanation:
First of all, calculate the area of the garden bed.
24 x 84 = 2016 inches squared
now, divide your answer by 8 (the amount of space needed for each plant)
2016 ÷ 8 = 252
I HOPE THIS WAS HELPFUL :-)
Answer:
She forgot to add the zero when she multiplied 27 x 50
Step-by-step explanation:
If you need one ask me I can try my best to explain
1/2 hr* (5 miles/ 1 hr)= 2.5 miles.
2 1/2 hrs* (5 miles/ 1 hr)= 12.5 miles.
Malia runs 2.5 miles and 12.5 miles in 1/2 hr and 2 1/2 hrs respectively.
Hope this helps~
