Answer 1

Answer:

B) 60.21 ft²

Step-by-step explanation:

Area of a triangle = 1/2bh

You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches

8’6”=102’

14’2”=170’

Now find the area

1/2 x 102 x 170 = 8670 in²

This is one of the answers, but the quetion asks how many quart feet you need.

So, convert it back to feet.

8670 x 0.06944444444 = 60.2083333

(You could also have converted the two lengths to feet. 8’6” = 8.5 ft.  14’2” = 14.16666666.  This way would probably have been faster.

1/2 x 8.5 x 14.166666 = 60.20833333)

what is the equation of the line in slope-intercept form?

Answers

Answer:

y = 8x

Step-by-step explanation:

Slope intercept form is y = mx + b

y = y coordinate

m = slope, rise over run

x = x coordinate

b = y-intercept, where the line crosses the y-axis.

y = mx + b

y = 80/10x + 0

y = 8x + 0

y = 8x

Answer:

y=-8x

Answer:

around 13.18

Step-by-step explanation:

the middle square is 2*2 = 4

the triangle then is 2^2 + 6^2 = 40  -> sqrt40 = 6.325

and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828

4+6.325+2.828 = 13.18

Answer:

which of the following is true about the function below? 1/√x-6

Answers

Answer:

Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)

49°

Answers

So for this triangle you are going to use Cos, which is adjacent/hypotenuse.
In this case x is your hypotenuse.

So your equation is going to be Cos(49)= 14/x.
So in order to get x, you are going to have to multiply x by each side. So:

x • Cos(49)= 14/x • x.
Multiplying x and x is going to cancel each other out so your new equation is going to be:

xCos(49)=14.

Now we are going to divide each side by Cos(49). Dividing Cos(49) by itself, will cancel itself out, so then your new equation will be:

x = 14/Cos(49)

Now you are going to put that into your calculator and your answer will be

x = 9.18.
