8' 4" − 2' 6" = ??' ??"
SCORPION-xisa [38]

Answer:

5' 10"

Step-by-step explanation:

We subtract by converting into one measurement. We will choose inches.

8'4"= 96"+4"=100" since 8' has 8(12) inches

2'6"=24+6=30" since 2' has 2(12) inches

Subtract.

100"-30"=70"

We convert back into feet and inches by dividing by 12.

70/12= 5' 10"

Find to the nearest tenth the radian meausure of 216 degrees.
cluponka [151]
There are 2 ways of measuring angle. It is either by radians or by degree. Radians is unitless or we just call it rad. A pi is equivalent to 180 degrees. A pi is equal to 3.14. So when we answer this we multiply 216 by pi/180 or 2pi/360. The answer is 3.7699 or 3.8 rad.

What is the equation of the line that passes through the point (-6,3) and has a slope of −4/3?
marin [14]

Answer:

y =  -  \frac{4}{3} x - 5

Step-by-step explanation:

The standard form for the equation of a line is

y = mx + c

We were told that

y = 3 \:  \:  \: x =  - 6 \:  \:  \: m =  -  \frac{4}{3}

*Note m is the slope*

Therefore

y =  mx + c \\ 3 = -  \frac{4}{3} (- 6) + c \\ 3= 8 + c \\ 3 - 8= c \\  - 5 = c

So the answer is

y =  -  \frac{4}{3} x - 5
