Answer:
-11.01 or -11
Step-by-step explanation:
x-10x=100
1x-10x=100
-9x = 100
-9x/-9 =100/-9
x = -11.01

Answer:
He will make $53,330
Step-by-step explanation:
In this question, we are tasked with calculating how much Mr Santiago will make in three years.
To calculate the future value of his earnings, we can use the formula for the future value of the salary
Mathematically, the FV = I(1 + r)^t
Where I is the initial amount of $51,000
r is the interest rate which is 1.5% = 1.5/100 = 0.015
t is the time in years which is 3 years
We plug these values into the equation above;
FV = 51,000(1+0.015)^3
FV = 51000(1.015)^3
FV = 53,329.59 which is $53,330 to the nearest whole dollars
Answer:
a) {P1P2, P1N, P1D,P2P1, P2N,P2D,NP1,NP2,ND,DP1,DP2,DN}
PP=2/12 NP=4/12 DP=4/12 DN=2/12
b) 1/3
Step-by-step explanation:
Let us call pennies by P1 and P2.
a)There are 12 possible outcomes as it is written above.
b)In order to have 11 cents we need a penny and the dime. There are 4 such possibilities (events). The total number is 12. So the probability is 4/12.
Answer:
Where m is the slope and b the intercept.
Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:
Wher y is the total cost and x the hours rented
Step-by-step explanation:
For this case we want to model the situation with a general equation given by:
Where m is the slope and b the intercept.
Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:
Wher y is the total cost and x the hours rented
