It rained 18 days during the month of April what percentage of day did it not rain during the month of April
kotykmax [81]
There are 30 days in April.

If 18 days had rain, it means 12 didn't.

18/30=x/100

Make sure both fractions can be made into fractions with a denominator of 100:

180/300=x/100

Divide 180/300 by 3:

60/100=x/100

This shows that the 18 days that did rain take up 60% of the whole month.

So then the remaining 12 days that didn't have rain must take up 40% of the month.

Solution:
40% of the days did not have rain during the month of April

The angle measurements in the diagram are represented by the following expressions.
Aleonysh [2.5K]

Answer:

x = 6

∠B = 126

Step-by-step explanation:

∠A = ∠B through alternate interior angles

∠A = ∠B

8x + 78 = 2x + 114

8x - 2x = 114 - 78

6x = 36

x = 36 ÷ 6

x = 6

∠B = 2x + 114

2(6) + 114

12 + 114

= 126

Plz help me!!!! I really need help!!!! <br><br> Solve for x
Delvig [45]

Answer:

try 35

Step-by-step explanation:

wow rly? delete my answer?

basically the angle 35 is on a parallel line which means that the angle opposite must be 35 as well since they are vertically opposite angles which makes them the same

then you use the alternate angles to work out the angle below 72 which will be 35

then lastly x should be 35 since vertically opposite angles are the same
