18% of 40 is 7.2

Change the percentage (18%) into a decimal by dividing it over 100:

18/100 = 0.18

Divide 7.2 by the decimal (0.18):

7.2 / 0.18 = 40

Answer:

92°

Step-by-step explanation:

We can say that the angle that is of x degrees is an inscribed angle because its vertex is on the circle and its sides are made up of rays. When you have an inscribes angle, it measures exactly half the angle it intercepts. In this case that angle is 184°. So, because of this we can say:

x = 184° / 2

x = 92°

A sack of potatoes weighs 14 pounds 9 ounces after wendy makes potato salad for a picnic the sack weights 9 pounds 14 ounces wha
dlinn [17]
For this case we have the following conversion:
 1 pound = 16 ounces
 Then we rewrite the sack weights:
 14 pounds 9 ounces = 14 9/16
 9 pounds 14 ounces = 9 14/16 = 9 7/8
 Then, we subtract both values:
 (14 9/16) - (9 7/8) = 4.6875 = 4 + 0.6875
 Rewriting:
 4 + 0.6875 = 4 + 6875/1000
 4 + 1375/200 = 4 + 275/40
 4 + 275/40 = 4 + 55/8
 Answer:
 
the weight of the potatoes wendy use for the potato salad is:
 
4 + 55/8 pounds
