Answer:
y=2x+5
Step-by-step explanation:
The y-intercept is when x is o so that will be 5.
To find the slope use the slope formula which is the change of y over the change of x. Choose 2 points.

Answer:
Step-by-step explanation:
mass of scaffold, m = 135 kg
mass of box, m' = 440 kg
let the tension in the left wire is T.
take moments about the right end.
According to the diagram,
135 x g x 3.3 + 440 x g x (6.6 - 1.7) - T x 6.6 = 0
4365.9 + 21128.8 - T x 6.6 = 0
T x 6.6 = 25494.7
T = 3862.8 N
53=20+x
Subtract 20 from 20 and 53
33=x
Hope this helps!
P.S.
Nice tab theme :P
In order to know how much of the 3/8 is in the 1/4, you calculate the quotient between 1/4 and 3/8, just as follow:
1/4 ÷ 3/8
you can convert the previous quotient into a multiplication by inverting the second fraction:
1/4 ÷ 3/8 = (1/4) x (8/3) = 8/12 = 2/3
Hence, 2/3 is what 3/8 is in 1/4
Answer:
Step-by-step explanation:
s+1+2s-1+90=180 degree(being linear pair)
3s+90=180
3s=180-90
s=90/3
s=30 degree
