Answer:none of them

Step-by-step explanation:

None of them equal 28.3. The closest is number 3, which is 26.3. Do the parenthesis, then the brackets, then add and subtract

None of them equal 28.3. Is there a chance you miss read the problem somewhere? Or is your teacher into doing trick questions?

John put away 36 of 48 shirts in his closet. Don has 84 shirts. If he put away the same percent, how many shirts did Don put in

Alexeev081 [22]

Answer:

Step-by-step explanation:

John's percentage:

36 and 48 have a common factor of 12 so divide both of them by 12.

36/12= 3 and 48/12=4 therefore

so 36/48= 3/4 which is 75% but we don't need to focus on the percent.

Don's no. of shirts:

we know Don has 84 shirts so we say

3/4 of 84= no. of shirts that Don put in his closet

84/4=21 21x3=63

Don put 63 shirts in his closet.

Hope that helped! Anymore questions just ask! :)

The answer is y=(1/2)x -5

You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m

Then work out like a one step equation

What is the equation of a sine function with an amplitude of 2 and a period of 4

antiseptic1488 [7]

Answer: C

Step-by-step explanation:

For this problem, we need to know the standard form of a sine function and the meaning of each part.

Standard form: $y=asin[b(x-h)]+k$

a=amplitude

b=period

h=phase shift

k=vertical replacement/shifting

Now that we know the standard form and the components, we know that we can forget about k and plug in 0 for h. This would leave us with $y=asin[b(x)]$ . We know that the amplitude is 2, therefore, a=2. To find the period, you divide 2π by the given period. $\frac{2\pi }{b} =\frac{2\pi }{4\pi } =\frac{2}{4} =\frac{1}{2}$ , therefore, b=1/2.

$y=asin[b(x)]$ [plug in a=2]

$y=2sin[b(x)]$ [plug in b=1/2]

$y=2sin(\frac{1}{2}x)$

Therefore, C is the correct answer.
