Okay here's an example so if we have 2, 3/2*1/2 we convert the mixed numbers to improper fractions. So in order to solve a mixed number you add the denominator, numerator and whole to get 7/2*1.2
So Multiple
7/2*1/2
Refine the fractions
7/2*2
Multiple the numbers 2*2=4 to get
7/4
and that equals 1, 3/4

Answer:
NM would actually represent a chord. Tangent are lines that would be outside of the circle.
Let us assume that the F is the first angle, S is the second and T is the third angle.
We know that
- F + S + T = 180°
- S = F + 20°
- T = 2S
We can substitute the S and T values into F, In this case, we will say that:
F + F + 20° + 2 (F + 20°) = 180°
2F + 20° + 2F + 40° = 180°
4F + 60° = 180°
4F = 180° - 60°
F = 120 ÷ 4
∴ F = 30°
S = F + 20°
∴ S = 50°
T = 2S
∴ T = 100°
To make sure that we have worked this out correctly, the angles should add up to give us 180°
Therefore, 30° +50° + 100° = 180°

Answer:
She can travel 21.75 miles in 3 hours.
Step-by-step explanation:
Firstly, you have to find out how many miles can Jill travel in 1 hour. So you divide it by 2 :
We have found out that she can travel 7.25 miles per hour. Next wr have to multiply it by 3 as the question says how far she run in 3 hours :
