C(20) in the context of the question means the cost to make 20 bracelets. The same with C(100) and C(500), except the answer changes from ' the cost to make 20 bracelets.' it changes to the cost to make 100 bracelets or 500 bracelets.

answers to c and e can be found using the formula C(b)=150+2b, though u replace b with either 100 or 500. C is $350, and E is $1150.

I believe in question G, 450 equals C(b). changing the formula to 450=150+2b. we subtract 150 from both sides so the equation looks like 300=2b. next divide both sides by 2, so b=150. Keoni can make 150 bracelets for his first batch.

Answer:

It's Micrograms. The rest are from the imperial system, which is the system that is commonly used in the United States. The metric system is an international system for scientists and mathematicians to use so that sharing and giving information is a lot easier when conveying to other people around the world.

1. For each of the following, indicate whether it is a question that involves permutations, combinations, or neither, and then a

krek1111 [17]

Answer:

Step-by-step explanation:

we are given some scenerios and we are to find out the total number of ways after mentioning permutations, combinations, or neither

a. How many ways can a coach choose two co-captains from 16 players in the basketball team?

Combination because both are having same position so order does not matter

16C2 = 120

b. In how many ways can seven questions out of ten be chosen on an examination?

Combinations because order of question does not matter.

10C7 = 10C3 = 120

c. Find the number of ways that 10 women in the finals of the skateboard street competition can finish first, second, and third in the X Games final.

Here order matters. Hence permutation

10P3 = 720

d. A postal zip code contains five digits. How many different zip codes can be made with the digits 0–9? Assume a digit can be repeated.

Here repitition is allowed. So neither permutation nor combination.

No of ways = $10^5$

7x + 3y = m

attashe74 [19]

7x + 3y = m

3y = m - 7x

y = (m - 7x) / 3

4( r + 3 ) = t

r + 3 = t / 4

r = ( t - 3 )/ 4

2x + b = w

2x = w- b

x = ( w - b ) / 2

x (1 + y) = 2

x = 2 / 1 +y

What is the surface area of a cylinder with base radius of 4 and height 5

shtirl [24]

Answer:

A= 226.08

Step-by-step explanation:

The formula for the surface area of a cylinder is A=2πrh + 2πr^2

So, plug in the numbers. π(pi)= 3.14

A= (2 × 3.14 × 4 × 5) + (2 × 3.14 × 4²)

You could use a calculator for the last few steps.

Multiply what's in the first set of parenthesizes: I25.6

Now, multiply the numbers in the other pair of parenthesizes: 100.48

Lastly, add the two numbers together: 226.08

226.08 is the surface area of the cylinder.
