JK is similar to PQ
KL is similar to QR

Make a proportion

\sf{ \frac{JK}{PQ} = \frac{KL}{QR} }

Plug in the numbers

\sf{ \frac{36}{6} = \frac{24}{QR} }

Cross multiply

\sf{36\times QR= 6 \times 24}

Solve for QR

\sf{ QR=4}

So your final answer is 

\boxed{\bf{4~centimeters}}

I pretty sure it would be 4 centimeters.

Because side JK (I find that really funny) is 36 centimeters, while side PQ is 6 centimeters. I multiplied that by 6, to get 36 and divided 24 by 6 which is 4 centimeters. Hope this helped!

Suppose a projectile is fired from a cannon with velocity v0 and angle of elevation θ. The horizontal distance Rθ it travels (in
jolli1 [7]

Answer:

0.25 rad to the nearest hundredth radian

Step-by-step explanation:

Here is the complete question

Suppose a projectile is fired from a cannon with velocity vo and angle of elevation (theta). The horizontal distance R(θ) it travels (in feet) is given by the following.  

R(θ) = v₀²sin2θ/32

If vo=80ft/s what angel (theta) (in radians) should be used to hit a target on the ground 95 feet in front of the cannon?

Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a radian.

(θ)= ?rad

Solution

R(θ) = v₀²sin2θ/32

If v₀ = 80 ft/s and R(θ) = 95 ft

θ = [sin⁻¹(32R(θ)/v₀²)]/2

= [sin⁻¹(32 × 95/80²)]/2

=  [sin⁻¹(3040/6400)]/2

=  [sin⁻¹(0.475)]/2

= 28.36°/2

= 14.18°

Converting 14.18° to radians, we have 14.18° × π/180° = 0.2475 rad

= 0.25 rad to the nearest hundredth radian

At the Canada Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The
kondaur [170]

Answer:

a) 54 mph to 144 mph

Step-by-step explanation:

We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

At least eight-ninths of the player's serves.

8/9 is approximately 89%

So

Mean: 99, standard deviation: 15

99 - 3*15 = 54

99 + 3*15 = 144

So the correct answer is:

a) 54 mph to 144 mph
