Answer:
15 students were on each bus.
Step-by-step explanation:
100 students have gone a field trip, 10 have travelled with their parents. So, you would do 100-10 to get 90. 90 students are riding the buses. To get the amount of students on each buses, you have to do 90÷6 to get 15.
My answer to this question C
Answer:
C) 4x^2 -8x +4[/tex]
Step-by-step explanation:
(-2x+2)^2
we apply (a+b)^2 formula
a= -2x and b= 2
Replace 'a' with -2x and 'b' with 2
(-2x)^2 is 4x^2
option C is the answer
The domain of this graph is that x ≤ 2.
The domain of any function is the number that you can put in for x. Since the highest number possible for x is 2, this means x must always be 2 or lower. Therefore we can write it as x ≤ 2
Answer:
$18,424.92
Step-by-step explanation:
Assuming this is compound interest, we'll have to use this formula
A = P(1 + r)ⁿ
A = Final amount (100,000)
P = Starting amount (?)
r = Rate (.07)
n = Years (?)
65 - 40 = 25
This means you will save for 25 years, making n = 25
So far, our equation looks like this: 100,000 = P(1.07)²⁵
To isolate the variable, P, divide both sides by 1.07²⁵
100,000/1.07²⁵ = P(1.07)²⁵/1.07²⁵
P = 18,424.917752223962
You would need to set aside around $18,424.92 if you want to accumulate $100,000 in 25 years with 7% compound interest rate.
