If im correct, 50.26
Step-by-step explanation:
Just use the radius to find the area as if it was a normal circle than divide by 4
Answer:
46
Step-by-step explanation:
The geometry can be modeled by a right triangle. The diagonal measure is the hypotenuse, and the height is one leg. The width is the other leg, and can be found using the Pythagorean theorem.
__
<h3>Pythagorean theorem</h3>
The relation between the leg lengths (a, b) and the hypotenuse (c) is ...
c² = a² +b²
Solving for b gives ...
b = √(c² -a²)
<h3>application</h3>
In this problem, we have c=55 and a=30. Then the width of the TV is ...
b = √(55² -30²) = √(3025 -900) = √2125
b ≈ 46.098
The width of the TV is about 46.
Answer:
the answer is 42.5
Step-by-step explanation:
4+2+5+31.5
= 42.5
Answer:
40%
Step-by-step explanation:
The first step is to calculate the unit selling price
= total sales/number of units
= 200,000/50,000
= $4
The unit variable expense can be calculated as follows.
= total variable expense/number of units
= 120,000/50,000
= $2.4
The contribution margin per unit can be calculated as follows
=selling price per unit- variable cost.
= $4-$2.4
= $1.6
Therefore the contribution margin ratio can be calculated as follows.
= $1.6/$4
= 0.4×100
= 40%
Answer:
5120
Step-by-step explanation:
divide the entire group into 10 groups where each group has a man and his wife.
number of ways of selecting 9 groups is 10C9 which equals 10 ways
the number of ways selecting 1 person from a group is 2C1 =2 .
So that means the number of ways of selecting 1 person from 9 groups is 2^9=512
number of ways to form the committee is 10*2^9=5120
