A student can pitch a fast ball at 65 miles per hour. Convert this

AnnyKZ [126]

Answer:

31.77 yd/sec

Step-by-step explanation:

<u>Conversions:</u>

1 mile = 1760 yards
1 hour = 3600 seconds

<u>Given:</u>

$\sf 65\:miles\:per\:hour=65\:miles/hour=\dfrac{65\:miles}{hour}$

Therefore, to convert 65 mph to yards per second:

$\implies \sf \dfrac{65\:miles}{hour}=\dfrac{65 \times 1760\:yards}{3600\:seconds}=31.777...\:yd/s$

a cone and a sphere have the same volume. the height of the cone is 96 units. what would be the values for the radius of the con

jolli1 [7]

The volume $V_c$ of a cone with base radius $r_c$ and height $h_c$ is

$V_c = \dfrac{1}{3}\pi r_c^2 h_c$

Similarly, the volume $V_s$ of a sphere with radius $r_s$ is

$V_s = \dfrac{4}{3}\pi r_s^3$

We know that $V_c=V_s$ and that $h_c=96$

So, we can set up the following equation:

$\dfrac{96}{3}\pi r_c^2=\dfrac{4}{3}\pi r_s^3$

We can simplify the common denominator 3, and pi appearing on both sides:

$96r_c^2=4r_s^3$

We can divide both sides by 4:

$24r_c^2=r_s^3$

Without further information, this is all we can say: the cubed radius of the sphere is the same as 24 times the squared radius of the cone.

-2.3 + 10.8 + (-8.4)

spayn [35]

Answer:

Step-by-step explanation:

Try and take it step by step.

-2.3 + 10.8 + (-8.4)

First let's rearrange and combine the negatives.

-2.3 + (-8.4) + 10.8

-2.3 + (-8.4) = - 10.7

Let's rewrite

10.8 - 10.7 and solve!

10.8 - 10.7 = .1
