Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100.
22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
Answer:
m∠A and m∠B = 130°
m∠D = 50°
Step-by-step explanation:
If all angles equal 360° and angles A and B are equal then we know the A + D and B + C equal 180° then it's simple subtraction to figure out the degrees of all the angles
To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
Answer:
Step-by-step explanation:
hello :
let: A = 3√16+√-9
16=4² and -9 = 9i² =(3i)² .... ( i² = -1)
√16 =√4² = 4 and √-9 = √9i²= √(3i)² ± 3i
A= 12 ± 3i
