Answer:
13
Step-by-step explanation:
Evaluate 3² then add and subtract, that is
10 + 3² - 6
= 10 + 9 - 6
= 19 - 6
= 13
You can do 1/24; 3/24; 5/24 in that order
Answer:
It takes Jane 2 2/3 minutes
It takes Joan 5 1/3 minutes
Step-by-step explanation:
let j = time it takes Jane
let 2j = time it take Joan
j + 2j = 8
3j = 8
j = 8/3 or 2/23
2j = 16/3 or 5 1/3
Answer:
d: 20
Step-by-step explanation:
alternative angle
Answer:
See below.
Step-by-step explanation:
In polar coordinate system, we have two parameters describing a point. The first one is its distance from the origin and second its angle with respect to the positive X axis.
The point ( 3 , pi ) will have a distance of 3 units from the origin. The angle made is pi radians or 180 degrees. The negative Y axis is at 180 degrees from the positive X axis.
Hence the point at a distance of 3 units on the negative Y axis is ( -3 , 0 )
