Answer:
a. x = 4 b. x = 7
Step-by-step explanation:
a. They are both congruent right angles because of the alternate exterior angles theorem
90-4 = 86
86/21 = 4
b. The angles are congruent because of the corresponding angles postulate
75+2 = 77
77/11 = 7
Area= r*r*π (π ≈ 3.14)
⇒ Area= 4*4* π= 50.265
The area of the circle is 50.265~
Answer:
56 cupcakes
Step-by-step explanation:
First, I convert 3/5 to a percent because I prefer to work with percents:
3/5 = 0.6 = 60%
Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:
100 - 60 = 40%
Finally, multiply the total cupcakes by the percent as a decimal:
140 × 0.4 = 56
Answer:8.9477 mph
Step-by-step explanation:To convert a meter per second measurement to a mile per hour measurement, multiply the speed by the conversion ratio. One meter per second is equal to 2.236936 miles per hour, so use this simple formula to convert:
Step-by-step explanation:
let the percent of found balloons be x
given,
total number of balloons= 70
number of found balloons= 28
according to the question,
x% of 70= 28
x/100 × 70 = 28
x=40
hence 40% of the balloons were found
