Answer:
=64 ft
Step-by-step explanation:
The wire, the pole and the flat surface form a right triangle with a base angle of 40°. The pole is the height of the triangle and is opposite the angle 40°.
Therefore we can use the trigonometric ratio -sine of the angle 40° -to find the height.
Sin∅ =opposite/hypotenuse
opposite=hypotenuse × sin∅
=100ft × Sin 40°
=64.28ft
≅64 ft
Answer:
Prob = 0.514
A. independent
Step-by-step explanation:
The probability that the club chooses a girl and then a boy for the representative spots
Total = 15
Boys = 6
Girls = 9
Prob of 2 person, a girl and a boy
=( 9C1*6C1)/(15C2)
= (9*6)/(105)
= 54/105
= 0.514
Step-by-step explanation:
5ab + 8c
Putting values of a = 3 b = 2 and c = 9
5(3)(2) + 8(9)
30 + 72
102
The answer is c. 46<span>
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 </span>× 2 = 46<span>).</span>
