Answer:

5 3/8

Step-by-step explanation:

3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6

Get a common denominator for the right side

3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18

Combine like terms

3 1/8 ÷(x−4 7/28 )= 1 32/18

3 1/8 ÷(x−4 7/28 )= 2 14/18

3 1/8 ÷(x−4 7/28 )= 2 7/9

We have a ÷ b = c

Rewriting as a ÷c = b

3 1/8 ÷ 2 7/9 = (x−4 7/28 )

Changing from mixed numbers to improper fractions

25/8 ÷ 25 /9 = (x−4 7/28 )

Copy dot flip

25/8 * 9/25 = (x−4 7/28 )

9/8 = (x−4 7/28 )

Add 4 7/28 to each side

9/8 + 4 7/28 = (x−4 7/28 )+ 4 7/28

Simplifying the fractions

9/8 + 4 1/4 = x

Getting a common denominator

9/8 + 4 2/8 =x

4 11/8 =x

4 + 8/8+3/8 =x

5 3/8

Of the 8 students in the chess club, three will represent the club at an upcoming competition. How many different 3-person teams

xz_007 [3.2K]

I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have

C(8,3) = 8!/(8-3)!3!
C(8,3) = 56

There are 56 3-person teams that can be formed from the 8 students.

Find the volume of each figure. Round your answers to the nearest hundredth, if necessary

SCORPION-xisa [38]

Answer:

666.67π .ft^3

here's your solution

=> radius of cone = 10 ft

=> height of cone = 20 ft

=> volume of cone = πr^2h/3

=> putting the value of radius and height

=> volume = 10^2*20/3π

=> volume = 666.67π .ft^3

hope it helps
