The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that r
epresents the situation?
A) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
B) It is linear because the function is continuous.
C) It is nonlinear because the final cost is determined by multiplying each price tag by 0.75.
D) It is nonlinear because the price tag and final cost columns do not have the same common difference.

Answer:one solution
Step-by-step explanation:
Given
a=42
b=34
angle A=117
using sine rule
sinB=0.7212
and A+B+C=180
Thus 2 triangles can be formed with given value
Answer:
The systems of equation are .
Vanessa worked for<u> 6 hrs </u>and Geneva worked for <u>15 hrs</u> to earn exactly $240.
Step-by-step explanation:
Let the number of hours worked by Vanessa be 'v'.
Let the number of hours worked by Geneva be 'g'.
Given:
Total number of hours worked = 21 hours
So we can say that;
Total number of hours worked is equal to sum of number of hours worked by Vanessa and number of hours worked by Geneva.
framing in equation form we get;
⇒ equation 1
Also given:
per hour earnings of Vanessa = $10
per hour earning of Geneva = $12
Total they need to earn = $240
So we can say that;
Total they need to earn would be equal to sum of per hour earnings of Vanessa multiplied by number of hours worked by Vanessa and per hour earning of Geneva multiplied by number of hours worked by Geneva.
framing in equation form we get;
⇒ equation 2
Hence The systems of equation are .
On Solving above equations we get;
First we will multiply equation 1 by 10 we get;
⇒ equation 3
Now Subtracting equation 3 from equation 2 we get;
Dividing both side by 2 we get;
Now Substituting the value of g in equation 1 we get;
Hence Vanessa worked for<u> 6 hrs </u>and Geneva worked for <u>15 hrs</u> to earn exactly $240.
Answer:
10 in
Step-by-step explanation:
So we want to consider the surface area of this sphere.
The formula for surface area of a sphere is .
So we have that the surface area is .
So I'm going to replace in
with
.
Now our main objective here is to solve for :
Divide both sides by :
This gets us by itself:
What number squared gives you 25? If you don't know, just take the square root of both sides giving you:
Now you can just put in your calculator. You should get 5.
5 is the radius
The diameter is twice the radius.
So 2(5) is 10, so the diameter is 10 in.
