Answer:
Step-by-step explanation:
5 men do 1 unit of work in 1 hr. 1 man does 1/5 unit of work in 1 hr. 2 men do 2/5 units of work in 1 hr. Therefore 2 men will take 5/2 hours to dig 1 hole and take 5/4 hrs to dig half a hole.
The second brand has the lower price because the first would equal to $4.50 and the second $4.30 the second brand is lower priced.
1/2x3/4=3/12
3/12 simplified is 1/4
To answer this question you need to understand the relationship between the hypotenuse and the 2 other sides of a right triangle. We use The pythagorean theorem to help us see the relationship. 3^2+4^2=c^2, so 25=c^2. C=5.
You will use the lines to show 3 and 4 and the hypotenuse is the slanted side. See picture.
