Answer:
Step-by-step explanation:
let the number of dimes=x
and number of quarters=y
x=2y
0.10 x+0.25 y=2.25
or 10x+25y=225
divide by 5
2x+5y=45
2 ×2y+5y=45
4y+5y=45
9y=45
y=45/9=5
x=2y=2×5=10
Hence dimes=10
quarters=5
So each book is an average of 2.8 cm
so 120 divided by each book=number of books
120/2.8=42.85
round down since you can't fit .85 of a book on a shelf
the answer is 42 books
Your problem statement is missing the formula Carrie came up with. It should be The one she started with, divided by m.
... G/m = a
For the values given, the acceleration is
... (7.92 N)/(3.6 kg) = 2.2 m/s²
_____
The unit of newtons is abbreviated N.
1 N = 1 kg·m/s² so dividing by kilograms leaves units of m/s², which are the units of acceleration.
Very likely, your question is not concerned with the units, just the number: 2.2. It's a straight division problem, easily handled by hand, by calculator, or in your head (after you realize 7.92 = 7.2×1.1 = 2×3.6×1.1).
Choice d because solid dot means or equal to and greater means to the right
Answer:
13.92
Step-by-step explanation:
We have that the critical z-score associated with 85% to the left is 1.04, we know that by table.
So we have to:
m + z * (sd) = 16
where m is the mean, z is the critical z-scor and sd is the standard deviation, if we replace we are left with:
m + 1.04 * (2) = 16
m = 16 - 1.04 * (2)
m = 13.92
Therefore, the average weight if 85% of cucumbers weigh less than 16 ounces is 13.92
