The parking lot for a hotel should have 114 parking spaces. If ech row can have 13 parking spaces, then the minimum nukber of ro

MArishka [77]

So @mathmate deleted my comment because "I wasn't explaining my answer" well I did

I clearly stated that you have to make educated guess and I showed how I GOT my answer

so i guess here is my "proper" answer

There is no specific formula for this, so you can make an educated guess

for example:

13*5 = 65 (this isn't right because we need a minimum of 114)

so we continue the guessing

I then next tried

13*9

I got 117,

117 is more than 113

making 9 the minimum amount of rows for the hotel parking lot

there ya go @mathmate is that clear enough?

What is the answer to this in cm

jasenka [17]

The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
$s = (2\pi r)( \frac{x}{360})$
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.

s = 2π(3.5)(1/2) ≈ 11.00

Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

Which expression is equivalent to √2x^5/18? Assume x > 0.

lord [1]

$\sqrt{\dfrac{2x^5}{18}}=\sqrt{\dfrac{2}{18}\cdot x^2\cdot x^2\cdot x}=\sqrt{\dfrac{1}{9}\cdot x^2\cdot x^2\cdot x}=\sqrt{\dfrac{1}{9}}\cdot\sqrt{x^2}\cdot\sqrt{x^2}\cdot\sqrt{x}=\\\\\\=\dfrac{1}{3}\cdot x\cdot x\cdot\sqrt{x}=\boxed{\dfrac{x^2\sqrt{x}}{3}}$

Answer A.
