Answer:
the angle which is equal to its supplement is 90 degree
Answer:
C. 
Step-by-step explanation:
To find the number of black ribbons one would have subtract the amount of red ribbons from the total number of ribbons. Then one would have to express it as a proportion. Part over whole equals percent over 100. The number of black ribbons over total ribbons equals "b" over 100.
4b+6=5 —— that’s correct because it’s asking for the sum of 4 times and number and 6=5 and sum is addition
Yeah, I gotta read the questions better.
Perimeter not area.
diagonal length = √((28 - 12)² + (24 - 10)²) = 21.26
P = 12 + 10 + 28 + 24 + 21.26 = 95.26 units
sphere surface area = 4πR²
R = √(379.94 / 4(3.14) = 5.5 in
D = 2R = 11 inch
Answer:
21 & 22
42.25 ÷ 2 = 21.125.
21.125 rounded to the two nearest whole numbers is 21 and 22.
21 and 22 are the closest integers to 21.125.
The answer is 21 and 22.
Hope it helps!
