Answer:
The Zero Property of Multiplication.
Step-by-step explanation:
The Zero Property of Multiplication states that the product of any number you multiply by zero is zero.
Examples:
0 x 1 = 0
0 x 2 = 0
0 x 3 = 0
0 x 100 = 0
etc.
1. There are 16 cups in one gallon.
So if he eats 4 cups a day, 7 days a week, the equation would look like
4*7=36, meaning he eats 36 cups a week. To convert to gallons divided through total by the amount of cups per gallon: 36/16=2.25
So he eats 2.25 gallons, or 2 gallons and 4 cups of brains per week.
2. One pint is the equivalent of 94 teaspoons. So in one hour, she ate 3 pints or 288 teaspoons of ice cream. Since there are 60 minutes per hour, that means 3 hours is equal to 180 minutes. So in order to figure out how many teaspoons she ate per minute we should divide the total number of teaspoons she ate by the total amount of minutes: 288/180= 1.6 teaspoons per minute.
3. There are 60 seconds in a minute, and 4 quarts in one gallon. So to make this simpler, we will start by converting the gallons to quarts: 4 gallons = 16 quarts. So that means 16 pints per minute. To figure out how many per second, we divide the number of quarts by the number of seconds in one minute: 16/60= .27, so .27quarts per second.
Answer:
No i dont think so but im not sure
Step-by-step explanation:
For the first equation αβ = 2/8 = 1/4 and α+β = -(-1/8) = 1/8
for the second equation (α-2)(β -2) = n/m and (α-2 + β-2) = 3/m
(α-2)(β -2) =
αβ + 4 - 2(α+β) Substituting values for αβ and α+β obtained earlier we have:-
1/4 + 4 - 2(1/8) = 4 1/4 - 1/4 = 4
so n/m = 4......................................(1)
(α-2 + β-2) = α + β - 4 = 1/8 - 4 = -3 7/8 = 3 / m
so 3 / m = -3 7/8 .............................(2)
from equation (2):- m = -24/31
and therefor n = 4 * -24/31 = -96/31
The algebra is a bit messy but i think its right
