Answer:
Step-by-step explanation:
<u>Given</u>
- Total number of participants= 80
- Male = x
- Female = 80 - x
- Average = 58.5
- Average for male = 64
- Average for female = 56
<u>Equation to reflect the sum:</u>
- 64x + 56(80 - x) = 80*58.5
- 64x - 56x = 80*(68.5 - 56)
- 8x = 80*2.5
- x = 25
<u>The answer is </u>25 male participants
Answer:
115%
Step-by-step explanation:
5 is completely irrelevant, Vertical angles are congruent.
1
Step-by-step explanation:
Seeing its an arithmetic sequence
T1=1......T2=2.....T3=3
To get your constant difference
T2=T1 is also equals to T3=T2
so 3-2=1 and 2-1=1
therefore the constant difference is 1
Answer:
cups of carrot.
Step-by-step explanation:
Let's set up proportional equation.
6 people need 2 cups of carrots
Let 16 people need x cups of carrots.
We could form ratio for number of people to cups of carrot used as
6:2
16:x
So, proportional equation would be
Cross multiply
32=6 x
Divide both sides by 6.
x=
Divide to get mixed number
x=5
Simplify the fraction
x= cups of carrot.
