Answer:
a = 5/4
Step-by-step explanation:
To make the second number in this ratio be 1, you need to multiply the whole ratio by 7/4:
(7/4)(5/7) : (7/4)(4/7) = 5/4 : 1 = a : 1
a = 5/4
Answer:
Step-by-step explanation:
The area of a sector with measure 
in degrees is given by 
, where 
is the radius of the sector.
What we're given:
Solving, we get:
*Notes:
- units should be in square meters (area)
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
1. 1/9
2. 0
3. -9
4. -1
Reasoning: To get the opposite of a number just add a negative sign or take it away. This can be done to all numbers other than 0
Answer:
y-8x=-2
Step-by-step explanation:
so the slope of the perpendicular line has to the negative receprical of the slope of this line which gives
-(-8)=8
let us put all the equations into slope intercept form
a.y=-8x+6
b.y=-1/8x-5
c.y=1/8x-5
d. y=8x-2
y=mx+b
as you can see the only line with a slope of 8 is y-8x=-2
