Answer:
6 m by 8 m
Step-by-step explanation:
The sum of two adjacent side lengths is half the perimeter, so is 14 meters. Two numbers differing by 2 that have a sum of 14 are half that total plus or minus have the difference: 7 ±1 = 6 and 8.
The room is 6 meters wide and 8 meters long.
Answer:
Here is a generic way to set up this type of algebra problem.
d = total amount of dirt at the site (tons)
r = rate or removal (tons/hr)
t = time it takes to remove all of the dirt (hr)
d = rt
The total amount of dirt equals the removal rate times hours spent removing all the dirt.
Since you want to solve for t, divide both sides by r
t = d/r
72 minutes
convert 8 hours to minutes ⇒ =8 × 60 = 480 minutes
15% of 480 = 0.15 × 480 = 72 minutes
Answer: The slope is -32
Explanation:
Start with the slope formula:
m= (y2 - y1) / (x2 - x1)
Substitute point values in the formula
m = (-25 - 7) / (85 - 84)
Simplify each side of the equation
m= (-25 - 7) / (85 - 84) = -32/1
Solve for slope (m)
m= -32
Answer:
<em>A. 35 deg</em>
