Answer:49 sec

Step-by-step explanation:

Given

Maximum speed to reach is 183.58 mi/h

Length of course is 5 mi

acceleration rate is defined by 60mi/h in 4 sec

therefore acceleration(a) $=\frac{v-u}{t}$

$a=\frac{60\times 60\times 60}{4}$

$a=54\times 10^3 mi/h^2$

To reach a speed of 183.58mi/h with an acceleration of $54\times 10^3 mi/h^2$

Using equation of motion

v=u+at

$183.58=0+(54\times 10^3)t$

$t=\frac{183.58}{54\times 10^3}$

t=0.00339 hours

t=12.23 s reach maximum speed

To complete course it takes

$s=ut+\frac{1}{2}at^2$

$5=0+\frac{1}{2}\times 54\times 10^3 \times t^2$

t=0.01360 hour

or $t=48.98\approx 49 s$

What is the answer 8x-22=-60

solmaris [256]

$8x-22=-60\qquad|\text{add 22 to both sides}\\\\8x-22+22=-60+22\\\\8x=-38\qquad|\text{divide both sides by 8}\\\\\dfrac{8x}{8}=\dfrac{-38}{8}\\\\x=-4.75$

If EFGH is a parallelogram, then ___________________.

VikaD [51]

Some parallelograms are also a rhombus.
So that's why the answer is choice B.

Note: Any rhombus is a parallelogram, but the other way around isn't true. For example, a rectangle that isn't a square is also not a rhombus. Any rectangle is a parallelogram. Not all parallelograms are rectangles.
