There are 4 weeks in a month.
All the numbers in the question are saying how much she will pay per week,so all we have to do is multiply each number by 4.
39.00<span>×4=156
15.00</span><span>×4=60
17.50</span><span>×4=70
Now all we have to do is add.
156+60+70=286.
Your answer will be that Jane has to pay 286 dollars per month on the car.</span>
Answer:
k = -6.
Step-by-step explanation:
We need to make the left side of the second equation a multiple of the left side of the first one.
We can do this by making k = -6 ( because -15/10 = -6/4).
The second equation becomes
-15x - 6y = 14
Now multiply this by -2/3. We get
10x + 4y = -28/3
but the first equation is 10x + 4y = -3 .
So there are no solutions.
So the answer is k = -6.

Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6

to solve this question, we need to know how many grains is in 1 gram
now let 300 grains be equal to x grams
300 grains will weigh 19.44g
Answer:
y=0.2x+29
Step-by-step explanation:
Given that:
y is the total monthly of the A Fee and Fee plan.
x is the number of monthly minutes used.
- If a customer uses 290 minutes, the monthly cost will be $87, we have the pair (290, 87)
- If the customer uses 980 minutes, the monthly cost will be $225, this is the coordinate pair (980, 225).
We want to obtain an equation in the form: y=mx+b
First, let us determine the slope, m
Given points (290, 87) and (980, 225):
<u>Slope</u>
Next, we determine the y-intercept, b.
Substituting the pair (290, 87) and m=0.2 in y=mx+b, we obtain
87=0.2(290)+b
b=87-0.2(290)=29
Therefore, our equation in the form y=mx+b is:
y=0.2x+29
