You need to write simple equation:
90\frac{mile}{h}=90*1,609\frac{km}{h}=144,81\frac{km}{h}

A rectangular playground is to be fenced off and divided into two parts by a fence parallel to one side of the playground. 240 f
lozanna [386]
Let's look at the picture, let's imagine that the gray line is the perimeter fence and that the red OR the blue is the one dividing it. We can see that the blue line is longer than the red one, so it will be advantageous, to have a bigger area, to have the dividing fence the smallest possible.
Let's say then that the width (W) is bigger (or equal) to the length (L), so we have:
W \geq L

W+W+L+L+L=240

2W+3L=240

W=\frac{240-3L}{2}
The area is W*L, so we have
A=W*L=L*\frac{240-3L}{2}=\frac{-3}{2}(L^2-80L)=\frac{-3}{2}L(L-80)
this function is a parabola facing down, its zeros are 0 and 80, therefore its maximum is when L=40
hence, L=40 and W=(240-120)/2=60
It will be a rectangle, measuring 60x40 and the divinding fence will be 40

How would I solve for slope on an equation similar to 8x+2y=5?
djyliett [7]
Well make the equation into slope intercept form: y=mx + b and whatever the coefficent is to x will be your slope 

8x+2y= 5  can be written as y= (-8/2)x + (5/2) so the slope would be (-8/2)

Among fatal plane crashes that occurred during the past 5050 ​years, 699699 were due to pilot​ error, 8888 were due to other hum
lapo4ka [179]

Answer: Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.

Step-by-step explanation:

Since we have given that

Number of crashes due to pilot error = 699

Number of crashes due to other human error = 88

Number of crashes due to mechanical problems = 156

Number of crashes due to sabotage = 164

Total number of crashes = 699+88+156+164 = 1167

So, Relative frequency distribution :

Pilot error = \dfrac{699}{1167}\times 100=59.89\%

Human error = \dfrac{88}{1167}\times 100=7.54\%

Mechanical problems = \dfrac{156}{1167}\times 100=13.36\%

Sabtoge = \dfrac{164}{1167}\times 100=14.05\%

Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
