The answer to this is letter C: <em>This equation is an example of converting by using proportion.</em> The proportion used here is the measurement of something in inches to the measurement of something in ft. The ratio would always be constant, hence, the equality sign.
Answer:
The total surface area is 140.4
Step-by-step explanation:
If we start with the larger surfaces on the top and bottom, we can find both of their surfaces by multiplying 4 by 6.5.
4*6.5=26. Since there are 2 of these surfaces, we can multiply 26 by 2 to get 52.
Then, we can find the surface area of the sides by multiplying 6.5 by 3.4.
6.5*3.4=22.1 Since there are four of these surfaces, we can multiply 22.1 by 4 to get 88.4.
Now, all we have to do is add them together.
52+88.4=140.4
The total surface area is 140.4
Hope this helps! :D
Answer:
55
Step-by-step explanation:
along line s, r intersects it, and you can see a right angle
90+35+angle 2 =180
you end up with 55, which is the measure
For 1/3 times 2/5: to find the product, multiply the numerators and multiply the denominators. the product is 2/15. for 2/5 divided by 3/5, multiply by the reciprocal. the product is 10/30 which can be simplified to 1/3.
