Answer:
1°F to 7°F is the best range to store ice cream.
Step-by-step explanation:
The ideal storage temperature of ice cream = 4°F
The allowance in the temperature is 3°F
So, the range of the store = 4°F ± 3°F
Now, 4°F + 3°F = 7°F
and 4°F - 3°F = 1°F
Hence, 1°F to 7°F is the best range to store ice cream.
To start off, you should make each fraction have a common denominator.
2*3 = 6
3*2 = 6
The lowest common denominator is six.
so 3 3/6 + 2 2/6 = 5 5/6
Hopefully that helps!
Answer:
7088 m²
Step-by-step explanation:
The area of the half-cylinder is half the area of a cylinder with the same dimensions. This half-cylinder has a radius of 0.3 m and a length of 0.8 m, so its area is ...
A = πr(r +l) = π(0.3 m)(0.3 m+0.8 m) = 0.33π m² ≈ 1.0362 m²
The area of the bottom part of the box is the sum of its lateral area and its base area.
lateral area = Ph = (2(0.6m +0.8m))(0.75 m) = 2.1 m²
base area = lw = (0.8 m)(0.6 m) = 0.48 m²
The total area is then ...
total area = half-cylinder area + lateral area + base area
= 1.0362 m² +2.1 m² +0.48 m²
= 3.6162 m²
__
The area for 1960 mailboxes will be 1960 times this area, or ...
area for week's production = 1960 × 3.6162 m² = 7087.752 m²
It will take about 7088 square meters of aluminum to make these mailboxes.
There are 2 dollars so that would equal 20 dimes.
Proof:
10 cents = a dime
20 x 10 = 200 = 2 dollars
__
There are 35 cents to that would equal 3 dimes and 1 nickel.
Proof:
10 cents = a dime
5 cents = a nickel
3 x 10 = 30
1 x 5 = 5
__
So the final answer would be 23 dimes and 1 nickel.
