<h3>Answer:  62</h3>

Explanation:

K is the midpoint of segment JL

That means the smaller pieces JK and KL are the same length.

JK = KL

9x-5 = 7x+3

9x-7x = 3+5

2x = 8

x = 8/2

x = 4

This x value leads us to:

  • JK = 9x-5 = 9*4-5 = 36-5 = 31
  • KL = 7x+3 = 7*4+3 = 28+3 = 31

Both smaller pieces are 31 units each, which helps confirm we have the correct x value.

Therefore, JL = JK+KL = 31+31 = 62

If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hour<br><br>pls
alisha [4.7K]

First let's make both the miles and the hours ran improper fractions:

26+\frac{1}{5}=\frac{131}{5}\\ 5+\frac{4}{5}=\frac{29}{5}

So, to find our miles per hour, we have to divide the miles by the hours to get: \frac{\frac{131}{5}\text{miles}}{\frac{29}{5}\text{hours}}=\frac{131\text{miles}}{29\text{hours}} \\ \text{ Now we have to divide the top and the bottom by 29 to get our miles per hour so: }\\ \frac{\frac{131}{29}}{\text{hour}} \approx \frac{4.52 \text{miles}}{\text{hour}}

Find the volume of the solid where the cone and half sphere are hollow. Use 3.14 for П ; height is 19 in; radius is 5 in. Round
Vera_Pavlovna [14]

Volume of Solids

The volume of the solid is 758.83 in³

Step-by-step explanation:

Given that the cone and half sphere is hollow

The volume of the cone = 1/3 \pi r^{2} h\\

The Volume of the sphere  = 4/3 \pi r^{3}

So the Volume of the half sphere =2/3\pi r^{3}

The volume of solid = volume of cone + volume of the half sphere

V = V_{1}  + V_{2}

Given

height h = 19 in

radius r = 5 in

V_{1\\}  = 1/3 \pi r^{2} h

     = 1/3 × 3.14 × 5 × 5 × 19

     = 497.16 in³

V_{2}  =  2/3 \pi r^{3}

   = 2/3 × 3.14 × 5 × 5 × 5

   = 261.67 in³

V =  497.16 in³ + 261.67 in³

  = 758.83 in³

Hence the volume of the solid is 758.83 in³
