Okay. so, to find the answer for this, you should set the equation as 10.25x = 8,425. "x" equals the number of hours. What you should do is divide each side by 10.25 to isolate the "x". When you do that 8,425/10.25, you get 821.951 and other numbers or 822 hours when rounded to the nearest whole number. x is approximately 822. You would have to work about 822 hours to earn $8,425.
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
Solving (a): The distance between both
The equation of a circle is:
Where
P and Q can be rewritten as:
So, for P:
For Q:
The distance between them is:
Where:
--- 
--- 
So:
Solving (b): The radius;
In (a), we have:
--- circle P
--- circle Q
By comparison
<em>Hence, circle Q has a smaller radius</em>
Answer:
option 2
Step-by-step explanation:
I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.
4 years = 12 x 4 = 48 months
Option 1: 500 + 195 (48) = 500 + 9360 = 9,860
Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310
If he can wait six months, it will save him about $3,500 to go with Option 2.
14 and 21
14 + 7 is 21 and 21 + 14 is 35.
