11. 50 +17x = 356 where x = number of months

17x = 306

x =306 / 17 = 18 months answer

12. 3x + 21 = 60

3x = 39 x = $13 answer

13. 15(x - 20) = 375

15x - 300 = 375

15x = 675

x = $45 answer

If these two shapes are similar, what is the measure of the missing length w?

skelet666 [1.2K]

Answer:

w = x = 36

Step-by-step explanation:

In the largest triangle, the longest side is x

The shortest side = 18

In the smaller triangle the longest side is 6

The shortest side is 3

You can set up a ratio

x/18 = 6/3 Divide the right side by 3

x/18 = 2 Multiply both sides by 18

18 *x / 18 = 2 * 18

x = 36

The main show tank has a radius of 60 feet and forms a quarter-sphere. what is the volume of the quarter-sphere shaped tank? rou

schepotkina [342]

By definition, the volume of a quarter of a sphere is given by:
$V = (1/4) * (4/3) * (\pi) * (r ^ 3)
$
Where,
r: sphere radius
Substituting values we have:
$V = (1/4) * (4/3) * (3.14) * (60 ^ 3)
$
Making the corresponding calculation we have:
$V = 226080 feet ^ 3$
Answer:
The volume of the quarter-sphere shaped tank is:
$V = 226080 feet ^ 3$
