Answer:
P=100-0.18
Step-by-step explanation:
Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.
Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below;
- Make the equation equal to zero:
-Add 49 at both sides:
- Now, you must take the square root of both sides of the equation, then you obtain the following roots:
- Then you have:
Answer:
4p - 8.
Step-by-step explanation:
Perimeter = 2* length + 2 * width
= 2p + 2(p - 4)
= 4p - 8.
Problem 1
Answer: Choice A
Vertically stretching it by a factor of 2 is the same as compressing it horizontally by a factor of 2
====================================================
Problem 2
Answer: choice B
Add up the functions to get
M(s) + L(s) = (225+0.65s) + (54 + 1.15s)
M(s) + L(s) = (225+54) + (0.65s+1.15s)
M(s) + L(s) = 279 + 1.80s
The equation for the circumference is 2 pi r. You have the circumference given.
Now, divide that by pi to get 2 r.
This is approximately 11.63.
Now, divide that by 2 to get the radius.
Radius = 5.14 yards.
