Answer: 680
Step-by-step explanation:
3 parts are male and 1 part is female. This adds up to 4 parts = 1360
3 part - 1 part (male - female) = 2 parts of the original which is 1/2 of 4 parts
1/2 of 1360 = 680
Simple maths
Your answer is B. At a distance of 6 tick marks above 0 , Im sure
Answer:
Step-by-step explanation:
If a line is parallel to another it must have the same slope
The slope/intercept form of a line is y = mx + b where m is the slope and b the y intercept
The line y = 2x + 5 has slope 2
So the slope of the line that passes through (2,3) must also have the slope 2
We have
y = 2x + b; Substituting x =2, y =3 in this equation gives us
3 = 2 (2) + b or b = -1
Hence the equation of the line is
y = 2x -1
Cross-check
Substitute for x = 2 ==> y = 2(2) - 1 = 3 which is consistent
Answer:
This means the center is (-3,-8) and the radius is 9
Step-by-step explanation:
(x+3)^2 + (y+8)^2 = 81
The equation of a circle can be written as
(x-h)^2 + (y-k)^2 = r^2 where the center is (h,k) and the radius is r
We can rewrite the above equation as
(x- -3)^2 + (y - -8)^2 = 9^2
This means the center is (-3,-8) and the radius is 9
Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.
For (B) you just round up. So again $5280 rounds up to $5300.
