P = 540, the principal
R = 4.4% = 0.044, the rate, simple interest
A = 991.44, the current value
Let x = years that Sally has held the account
Then
P + PRx = A
or
540 + 540*0.044*x = 991.44
23.76x = 991.44 - 540 = 451.44
x = 451.44/23.76 = 19
Answer:
Sally has held the account for 19 years.
Step-by-step explanation:
First, We do the multiplication law. which states that if
R can occur multiple ways, n, then the total numbers of ways is just
In this case, we have 3 things to consider so we just do
number of sandwiches which is 3: Number of sides to choose from which is 2: And number of drinks: 2 so we do
So there is 12 possible combinations. Now let see which ones contine chips and juice.
We can make a tree diagram, and see that we can do
Chicken,Chips, and Juice
Turkey, Chicken,Juice
Or Veggie,Chicken, and Juice so there is 3 combinations that includes that.
So out of 12 combinations, there is 3 that favor our scenario so we say
Probability is 3/12=1/4=25%
Answer:
A. 144 ft^3
Step-by-step explanation:
Answer:
r = -23
Step-by-step explanation:
A slope of 1/2 means that for every y-value increase of 1, the x value will increase by 2.
Between -7 and 5, there was an increase of 12. So, the x value will increase by 24.
To find r, subtract 24 from 1
1 - 24
= -23
So, r = -23
The y-intercept would be (0,40000)
