Answer:
A person in a group where 5 people are sharing 3 small bags of snickers
Step-by-step explanation:
Let the number of calories in one bag of snickers =x
Number of calories in 3 small bags of snickers =3x
- If 5 people share 3 small bags of snickers, 1 person's share
Number of calories in 2 small bags of snickers =2x
- If 7 people share 2 small bags of snickers, 1 person's share
We then compare the two.
Let x=1
Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.
Answer:
Account A: Decreasing at 8 % per year
Account B: Decreasing at 10.00 % per year
Account B shows the greater percentage change
Step-by-step explanation:
Part A: Percent change from exponential formula
f(x) = 9628(0.92)ˣ
The general formula for an exponential function is
y = ab^x, where
b = the base of the exponential function.
if b < 1, we have an exponential decay function.
ƒ(x) decreases as x increases.
Account A is decreasing each year.
We can rewrite the formula for an exponential decay function as:
y = a(1 – b)ˣ, where
1 – b = the decay factor
b = the percent change in decimal form
If we compare the two formulas, we find
0.92 = 1 - b
b = 1 - 0.92 = 0.08 = 8 %
The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.
Account B recorded a greater percentage change in the amount of money over the previous year.
Answer:
1/2, 50%
Step-by-step explanation:
A cube has six sides. The probability of landing on a number less than four is 3/6 because there are 3 positive numbers less than 4. 3/6=1/2=50%
Hope this helps!

For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
Answer:
the college student has:
8 quarters
20 dimes
