Step-by-step explanation:
Given : A club has 28 members.
To Find : . How many ways are there to choose four members of the club to serve on an executive committee?
Solution:
We are supposed to choose four members of the club out of 28.
So, we will use combination
Formula :
n = 28
r = 4
Substitute the values :
Hence there are 491400 ways o choose four members of the club to serve on an executive committee
Answer:
28.2 US tablespoons
Step-by-step explanation:
If 8 tablespoons of extract are mixed with distilled water to total 300 mL, the final concentration is 28.2 US tablespoons.
8 tablespoons + 300 mL = 28.2 US tablespoons

Answer:
y = 5
Step-by-step explanation:
Since this is an isosceles triangle, Angle B and Angle C are equivalent. We can use this to find x
3x = 75
x = 25
Angles in a triangle add up to 180, so knowing the measure of Angle B and Angle C, we can find the measure of Angle A
Angle A = 180-(75+75)
Angle A = 180-150
Angle A = 30
We know Angle A = 4y+10
4y + 10 = 30
4y = 20
y = 5
