Answer:
Step-by-step explanation:
The measurement of area, perimeter, and volume is crucial to construction projects, crafts, and other applications. Area is the space inside the boundary of a two-dimensional shape. Perimeter is the distance around a two-dimensional shape such as a square or circle. Volume is a measure of the three-dimensional space taken up by an object, such as a cube. If you know the object's dimensions, then measurement of area and volume is easy. Surface area and volume formulas for all everyday geometric shapes can easily be found online, although it's not a bad idea to review how to derive these on your own should the need arise. You can also often get one of these from another; for example, if you know the formula for the area of a circle, you may be able to figure out that the volume of a cylinder is just the area of the associated circle(s) at the end times the cylinder's height.
16 it's just double the the denominator and the top number
If each of the 36 cans of vegetables were corn the cost would be 0.40*36 or $14.40. This is obviously not enough. For every tomato can you buy instead of corn the price goes $0.80 -$0.40 or $0.40 up. Knowing this all you need is to find how many corns to replace. To do this find the difference between the real cost and the all corn cost. This is $20.8-$14.4 or $6.40. Now to find the number of corns to be replaced just divide this by 0.40 to get 16. That means 16 corns need to be replaced by tomatoes. So there is 20 cans of corn and 16 cans of tomatoes. The answer is 20 cans of corn.
Answer:
B
9/12 carton
Step-by-step explanation:
Get both fractions to have the same denominator.
So make 3 into 12 by multiplying numerator and denominator by 4.
1×4/ 3×4 = 4/12
Now you can add the fractions.
5/12 + 4/12
= 9/12 Carton
3 * 7 = 21, so
Then
and you can rationalize the denominator to write this as
