There are 35 females performed in a dance recital.The ratio of men to women is 3 : 8. How many men are in the dance recital
Ipatiy [6.2K]

Answer:

13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.

Step-by-step explanation:

Be careful how you interpret this question. It reads like this.

3:8 :: x:35

In other words, the 8 and 35 females goes together.

Set this up as a proportion

3/8 = x / 35  Cross multiply

3*35 = 8x     Combine the left

105 = 8x       Switch

8x = 105        Divide by 8

x = 105 / 8     get the answer

x = 13.125       You cannot have 1/8 of a person. So what are you going to do?

You have to round down. x = 13. How close is this

13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.

How do I solve log(2)t^3-1=-3?
Ne4ueva [31]
Assuming you mean
log_2(t^3-1)=-3
remember
log_a(b)=c translates to a^c=b
translate

log_2(t^3-1)=-3 translates to 2^{-3}=t^3-1
\frac{1}{2^3} =t^3-1
\frac{1}{8} =t^3-1
add 1 to both sides
\frac{9}{8} =t^3
cube root both sides
\frac{ \sqrt[3]{9} }{2}=t

A sequence is shown below. 4, 8, 16, 32, . . . Which formula can be used to determine the nth term in the sequence? Use the form
zvonat [6]

Answer:

a8 = 512.

Step-by-step explanation:

This is geometric sequence with common ratio r = 2 and first term a1 = 4.

nth term = a1 r^(n-1)

So a8 = 4 2(^8-1)

= 4 * 2^7

= 4*128 = 512.
