Divide 28/4. Becomes 7 right? So, divide 7/4. And you'll get 1.75. Multiply 1.75 * 4. You'll get what you got if you divide by 7. So it's 1.75

A bottle of shampoo has a capacity of 0.43 L. How many milliliters of shampoo does the bottle contain? (1 L = 1,000 mL) A. 4.3 m
Finger [1]

Answer:

The correct answer is C

C. 430 mL

Step-by-step explanation:

We know that 1 liter is equivalent to 1,000 milliliters

1L = 1,000mL

So the number we have to go from liters to milliliters we multiply it by 1,000 and change the L per mL

0.43L = 0.43 * 1000 mL

0.43L = 430 mL

The bottle of shampoo contain 430 mL

if we look at the options they give us, we will see that it is equal to option c

A. 4.3 mL

B. 860 mL

C. 430 mL

D. 43 mL

Determine whether the statements are True or False. Justify your answer with an explanation.
frez [133]

Problem 1

<h3>Answer: False</h3>

---------------------------------

Explanation:

The notation (f o g)(x) means f( g(x) ). Here g(x) is the inner function.

So,

f(x) = x+1

f( g(x) ) = g(x) + 1 .... replace every x with g(x)

f( g(x) ) = 6x+1 ... plug in g(x) = 6x

(f o g)(x) = 6x+1

Now let's flip things around

g(x) = 6x

g( f(x) ) = 6*( f(x) ) .... replace every x with f(x)

g( f(x) ) = 6(x+1) .... plug in f(x) = x+1

g( f(x) ) = 6x+6

(g o f)(x) = 6x+6

This shows that (f o g)(x) = (g o f)(x)  is a false equation for the given f(x) and g(x) functions.

===============================================

Problem 2

<h3>Answer: True</h3>

---------------------------------

Explanation:

Let's say that g(x) produced a number that wasn't in the domain of f(x). This would mean that f( g(x) ) would be undefined.

For example, let

f(x) = 1/(x+2)

g(x) = -2

The g(x) function will always produce the output -2 regardless of what the input x is. Feeding that -2 output into f(x) leads to 1/(x+2) = 1/(-2+2) = 1/0 which is undefined.

So it's important that the outputs of g(x) line up with the domain of f(x). Outputs of g(x) must be valid inputs of f(x).

Can someone please help me with math.
Inessa05 [86]

4- 20

I created an equation for this one:

4x+x=100

  • 4x= four times the amount of the other number
  • x= the number
  • combine like terms

5x=100

  • divide by 5

x=20

5. One pretzel costs $3

Create an equation:

  • 2s+p=7
  • 4s+3p=17

Mulitply 2s+p=7 by -2 so you can use elimination.

  • -4s-2p=-14
  • 4s+3p=17

Combine equations

p=3
