Answer: the required answer is 1320
Step-by-step explanation:
Total people = 12
Different phone lines = 3
We will choose the person to answer the first phone in 12 ways.
Then choose the second person in 11 ways. (11 people left)
Then choose the third person in 10 ways. ( 10 people left)
The number of groups of 3 people can answer these lines
Hence, the required answer is 1320

<u>Step 1: Define</u>
<em>Identify</em>
a⁴ - 6b + 3b ÷ ac
<em>a</em> = -2
<em>b</em> = 6
<em>c</em> = 3
<u>Step 2: Evaluate</u>
- Substitute in variables: (-2)⁴ - 6(6) + 3(6) ÷ (-2)(3)
- Exponents: 16 - 6(6) + 3(6) ÷ (-2)(3)
- Multiply: 16 - 36 + 18 ÷ (-2)(3)
- Divide: 16 - 36 - 9(3)
- Multiply: 16 - 36 - 27
- Subtract: -47
Answer:
24 glasses
Step-by-step explanation:
We are given that
Estelle has juice=6 liters
She pours juice in one glass=0.25 L
We have to find the number of glasses of juice made by her.
Using unitary method
0.25 L juice pour in 1 glass
1 L juice pour in 1/0.25 glasses
6 liters juice pour in glasses=
6 liters juice pour in 24 glasses
Hence, she will make 24 glasses of juice.
Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90
