Answer:
A 1/2
Step-by-step explanation:
Ratio of short length to hypotenuse
= cos60
= 1/2
Answer:
not direct variation
Step-by-step explanation:
The equation for x and y in direct variation is
y = kx ← k is the constant of variation
y = 
is not in this form, thus not direct variation.
The equation for x and y varying inversely is
y = 
← k is the constant of variation
y = is in this form and represents inverse variation
I think 1 / 7 x 7 is the correct answer
Answer:
7. D:61
8. A:57
9. A: 47
Step-by-step explanation:
Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
