The volume<span> of a triangular </span>prism<span> can be found by multiplying the base times the height. I would be glad to answer the question if you gave me some reference numbers to plug into the formula to get the volume for you.</span>
Answer and explanation:
Benchmark fractions are fractions that are used as references in measuring other fractions. They are easily estimated and so can be used in measuring more "specific" fractions such as 1/5, 7/9, 3/7, 1/3 etc. If I wanted to measure 1 1/3cm for instance using a calibrated ruler, having centimeter measurements, I would first find 1cm on the ruler and then find half of one centimeter. Seeing that half is bigger than 1/3 but close, I could then estimate 1/3 to be somewhere less than 1/2 but a bit close to it
Answer:
1. $1.40 2. $8.40
Step-by-step explanation:
1. 7 divided by 5 is 1.4
2. 1.40 plus $7 equals $8.40
