1. If a and b vary inversely and b = 8 when a = 6:
b = k/ a
8 = k / 6
k = 6 * 8
k = 48
Function is:
b = 48 / a
2. When a = 30:
b = 48 / 30 = 8/5
b = 1.6
You would multiply that number by 1.175
Remember that 17.5%=17.5/100=0.175
I this case, there is a whole number that is increasing by 17.5% so we add a whole to the 17.5%
100%+17.5%=117.5% or 1.175
So if 'x' was the number, the expression would look like:
1.175x
14, 28 I think:) sorry if not
Answer:
the 2 is the ones 2 means 2
Step-by-step explanation:nothing
The complete question in the attached figure
we have that
<span>m∠4=68°
we know that
</span>m∠4 and m∠3 are supplementary angles
so
m∠3=180-m∠4----- m∠3=180-68------> m∠3=112°
m∠3 = m∠2 --------> by alternate interior angles
so
m∠2=112°
m∠1 = m∠4 --------> by alternate exterior angles
so
m∠1=68°
m∠5 = m∠4---------> by corresponding angles
so
m∠5=68°
the answers arem∠1=68°m∠2=112m∠3=112°m∠5=68°
