600kg=3men*4hours so we can say that:

50kg/(m*hr) (50kg=1 man*hour) so:

(4men*2hours)(50kg/(man*hour))=400kg

What is the slope and y- intercept of the line passing through (11,-3) and (7,9)

Misha Larkins [42]

Answer:

Slope is -3, y-intercept is 30

Step-by-step explanation:

You take the two points (11,-3) and (7,9), plug them into the formula y2-y1/x2-x2=m. Now, you have 9-(-3)/7-11 which gives you 12/-4, 12/-4 can be simplified into -3 which is your slope. To find y-intercept you must use the formula y=mx+b. Plug -3, your slope, into m, and any of the coordinates on your line into the y and x; I used (7,9). You solve for b from 9=-3*7+b. -3*7 gives you -21, now you have 9=-21+b, to get b by itself, you add 21 to both sides, 30=b. B is your y-intercept.

Why are there 27 cubic feet in one cubic yard

kobusy [5.1K]

One cubic yard is equal to 27 cubic feet because one yard is equal to 3 feet

Solution:

Given that, there 27 cubic feet in one cubic yard

Yard and feet are units of distance

1 Yard (yd) is equal to 3 feet (ft). To convert yards to feet, multiply the yard value by 3.

The conversion factor for 1 yard to 1 feet is given as:

$1 \text{ yard } = 3 \text{ foot }$

Now find for 1 cubic yard . Cubic yard means yard raised to power 3

Therefore,

$1\ yard^3 = (3)^3\ feet^3\\\\1\ yard^3 = 27 feet^3\\\\1\ cubic\ yard = 27\ cubic\ feet$

Thus one cubic yard is equal to 27 cubic feet

Therefore, there are 27 cubic feet in one cubic feet
