Answer:
Step-by-step explanation:
7.3×10^22 = 73,000,000,000,000,000,000,000
73,000,000,000,000,000,000,000 × 26,000,000 = 1,898,000,000,000,000,000,000,000,000,000 or 1.898 × 10^30
y=20
25+15=40
2y=40
40/2=20
About 135.
As the sample is random the number of monkeys likely to be in the zoo
= (22/65) * 400
= 135.38
42
73*11= 803
845-803= 42
We have:
rectangle 4.8 m × 3.8 m
two triangles with base b = 4.8 m and height h = 2.6 m
two triangle with base b = 3.8 m and height h = 2.9 m.
The formula of an area of a rectangle l × w:
Substitute:
The formula of an area of a triangle:
The Surface Area:
