Answer:
B
Step-by-step explanation:
Note:
1 gal = 4 quarts
1 pint = 0.5 quart
Re-writing all the choices in dollars and quarts and calculating how much each quart costs
A) $1 per 1 quart
B) $2 per gallon = $2 per 4 quarts = $2 ÷ 4 quarts = $0.50 per quart
C) $1.50 per 2 quarts = $1.50 ÷ 2 quarts = $0.75 per quart
D) $0.50 per 1 pint = $0.50 per 0.5 quart = $0.50 ÷ 0.5 quart = $1 per quart
If you compare all of the above, it is clear that answer B ($0.50 per quart) is the cheapest rate and hence the best deal.
Answer:
The ray that goes parallel to the main axis after passing through the lens should also be parallel from the object to the lens
Step-by-step explanation:
To form the image of an object using a convex lens, ray diagrams are used. The following steps are followed when drawing ray diagrams.
1) Light rays are drawn from the object incidented on the lens and parallel to the principal axis. The incident light refracts (bends) through the lens and converges at the focal point at the other side of the lens.
2) Another incident light passes through the optical centre undeflected and intersect with the refracted ray at the other side of the lens.
Based on the above points, Roshan made an error by drawing the ray that goes parallel to the main axis and after passing through the lens made the same ray to be parallel from the object to the lens instead of refracting (bending) after passing through the lens.
Maximum production p=552728
Step-by-step explanation:
The equation for maximum production is : 
The number of units of labor is x @$72
The number of units of capital is y @$40
The total cost of labor and capital is limited to $270,000, this can be written as;
72x+40y ≤ $270,000
Graphing the inequality to find values of x and y ,from the graph;
x=3750 units
y=6750 units

Answer:
C. 40 cm
Step-by-step explanation:
length of side of square = s
perimeter = s + s + s + s = 4s
We use the formula P = 4s
P = 4 * 10 cm
P = 40 cm
Answer: The perimeter is 40 cm.
Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.
An area has square units such as cm^2, in.^2, ft^2, etc.
Answer:
∠A = 32°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanA = 
= 
= 0.625, thus
A = 
(0.625) = 32°
