Answer:
the greatest common factor is 2, so the expression could be rewritten
For 10 gallons of sauce, we need 5 times as required for 2 gallons, therefore we need 4 * 5 = 20 bottles of ketchup.
Answer:
B
Step-by-step explanation:
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.
Answer:
True
Step-by-step explanation:
Firstly, “ % ” means percent, which, as it name says, is the amount of the number per 100 .
Take 5% for instance, 5 percent would mean 5/100
Likewise, x%=x/100
Now x% of y means x/100×y=xy/100
but also, y% of x means y/100×x=yx/100
and therefore these two are the same!
