The first one is $437.43 and the second is $2705.04 ($52.02 x 52 weeks in a year)
Answer: 31/4
Step-by-step explanation:
The 7 is basically the fraction has been 4/4 7 times, and the 3 means that after that we have 3 left over. So we do:
7×4=28
Then since we have 3 left over:
28+3=31
So the fraction would be 31/4
Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
Answer:
Step-by-step explanation:
To determine the area of the definite integral, we take each term and find its corresponding integral. We know that , so therefore we rewrite the expression as .
Now, we plug in each limit into the expression and find the difference between them:
Therefore,
A.
Multiply the number of days, x by 50 per day to get 50x.
Next multiply the number of miles driven to the amount she gets per mile: 0.60 x 200 = $120
Now add both together to equal the total of 1620.
The equation becomes: 50x +120 = 1620
B.
50x +120 = 1620
Step 1: subtract 120 from both sides ( subtraction property of equality):
50x = 1500
Step 2: Divide both sides by 50 ( division property of equality):
x = 1500 / 50
x = 30
C.
The trip lasted 30 days.
