I'm sure the measurement was made in grams because:
1. most cell phones weigh between about 100 and 150 grams
2. there's no cell phone that weighs 113 kg, 113 pounds, 113 ounces etc.
Answer:
length of each side of the room is 2√30 which is approximately 10.9545 ft
Explanation:
The area of the square can be computed as follows:
Area = l²
where l is the length of the side
We are given that:
area = 120 ft²
Substitute with the area in the above equation and solve for l as follows:
area = l²
120 = l²
l = √120
l = 2√30 ft
This is approximately equal to 10.9545 ft
Hope this helps :)
Answer: A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per pound and cashews cost $6.50 per pound, how many pounds of cashews should he use?
a 3
b 4
c 6
d 7
Step-by-step explanation:
3lbs of Cashews
n-4 < -3(2+n)
Remove parentheses:
n-4 < -6 - 3n
Add 3n to each side:
4n-4 < -6
Add 4 to each side:
4n < -2
Divide each side by 4 :
n < - 1/2 .
Any number less than -1/2 makes the original equation a true statement.
