Well what is 30x3 (because that is how you would find what is one third of unknown) then you find the answer witch is 90$
Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Arc length = Ф/360 * 2πr
= 30/360 * 2*3.14*10
= 1/12 * 62.8
= 5.23
In short, Your Answer would be 5.23 cm
Hope this helps!
If you would like to write 7/8 as a decimal, you can do this using the following steps:
7/8 = (125*7)/1000 = 875/1000 = 0.875 = .875
The correct result would be b. .875.
