Answer:

y = 4x - 32

Step-by-step explanation:

If you plug in x = 9, you get 4(9)-32, which equals 4.

I THINK y=4x-32. I’m not completely sure but I believe that’s correct.

Average speed = $\frac{Total Distance}{Total Time}$

Ishan's Speed uphill = 10mph

Time taken = 18 minutes = 18/60 = 3/10 hours

Now distance = rate × time

Distance traveled by Ishaan up hill = 10 × 3/10 = 3 miles

Now returning back home

Distance = 3 miles

Rate = 30 mph

So time taken = distance/ rate = 3/30= 1/10 hours = 1/10 ×60 = 6 minutes.

Now total distance traveled = 3 + 3 = 6 miles

Total time taken = 18 + 6 = 24 minutes = 24/60 = 2/5 hours

Average speed

= $\frac{6}{0.4}$

= 15 mph

Ishaan's average speed for the entire trip from home to the gift store and back is 15mph

Sphere with a volume of 1767.1 . what is the radius?

Llana [10]

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ V=1767.1 \end{cases}\implies 1767.1=\cfrac{4\pi r^3}{3}\implies 5301.3=4\pi r^3 \\\\\\ \cfrac{5301.3}{4\pi }=r^3\implies \sqrt[3]{\cfrac{5301.3}{4\pi }}=r\implies 7.4999\approx r$
