What is the span of the roof? A. 4 ft B. 12 ft C. 18 ft D. 24 ft
RoseWind [281]

Answer:

  D.  24 ft

Step-by-step explanation:

The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.

The span of the roof is 24 ft.

%  distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{(10-6)^2+(15-9)^2}\implies d=\sqrt{4^2+6^2}\implies d=\sqrt{52}
\\\\\\
d\approx 7.2

what's its speed?  well, it traveled √(52) in 2 seconds, so is simply √(52)/2, which is about 3.6 units per second.

3.9x + 1.4 = 17 what is the steps​
Vedmedyk [2.9K]

Answer:

x=4

Step-by-step explanation:

3.9x + 1.4 = 17

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

3.9x*10+1.4*10=17*10

39x+14=170

Subtract 14 from both sides:

39x+14-14=170-14

39x=156

Divide both sides by 39:

\frac{39x}{39}=\frac{156}{39}

x=4
