An artist is trying to choose 5 covers for children’s books. There are 10 different covers to choose from. How many ways can the
Aleksandr [31]

Answer:

252

Step-by-step explanation:

The order of the books isn't important, so we'll use combinations.

The number of ways to choose 5 books from 10 is:

₁₀C₅ = 10! / (5! (10 − 5)!)

₁₀C₅ = 10! / (5! 5!)

₁₀C₅ = 10×9×8×7×6 / (5×4×3×2×1)

₁₀C₅ = 252

In a reapeating musical pattern, there are 56 beats in 7 measures
anygoal [31]

Answer:

You will need to find the number of measures per beat (it will be a fraction): 7/56=0.125 Then, you multiply that by 104: 0.125x104=13 This means that there will be 13 measures after 104 beats.

Step-by-step explanation:

104 beats is multiplied with the decimal of the fraction of beats and measures which means it has been used with whole numbers

0.125 is not a whole number we know x 100 is 12.5 and we know x4 is 0.5

When we work with the first 4 multiples we can usually spot whether it would take more than 4 to round figure it to 0.5 to add to 12.5

There are 3 digits as decimals and x 100 quantifies.  just by adding 4 to x100 to each of them until a whole number found 12.5 + 0.5 = whole number = 13.

Find an equation of variation in which y varies inversely as x and y=5 and x=21. Then find the value of y when x=10.
finlep [7]

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 5 , x = 21

k = yx = 5 × 21 = 105

y = \frac{105}{x} ← equation of variation

When x = 10, then

y = \frac{105}{10} = 10.5
