What fratcion is equal to 50% of 1 third

Answers

Answer:

1/6

Step-by-step explanation:

To know what fraction is equal to 50% of 1/3, we have to convert the percentage into a fraction first.

50% = 50/100

So 50% of 1/3 = 1/3 * 50/100

= 50/ 300

= 5/30

= 1/6

y is directly proportional to the square root of x
If y = 32 when x = 64 find,
y when x = 25

Please help

Answers

Answer:

y = 20

Step-by-step explanation:

Given y is directly proportional to [tex]\sqrt{x}[/tex] , then the equation relating them is

y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion

To find k use the condition y = 32 when x = 64, then

32 = k[tex]\sqrt{64}[/tex] = 8k ( divide both sides by 8 )

4 = k

y = 4[tex]\sqrt{x}[/tex] ← equation of proportion

When x = 25, then

y = 4[tex]\sqrt{25}[/tex] = 4 × 5 = 20

Plentiful Pies determines its annual profits
in dollars using p(x) = 65x - 0.3x2 where x
represents the numbers of pies sold. If Plentiful
Pies sells 175 pies in a year, what will their
annual profits be?

Answers

Answer:

The annual profits will be 2187.5

Step-by-step explanation:

p(x) = 65x - 0.3x^2

I am guessing that the 2 was supposed to be a square.

Simply plug in the number of pies sold:

p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

Which descriptions of the figure MUST be true? Select all that apply.

Please help me

Answers

The true description of the figure here are:

x = 8MN = 52D

How to solve for the proof of the figure

We have x to be = 8

The value of MN is said to be 5x + 12

We have to see if 5x + 12 = MN = 52 given that X is 8

We then insert the value

5 * 8 + 12 =

40 + 12 = 52

Hence it is confirmed that the value of x is 8, and MN is 52.

Answers

Answer: $60.1875

Step-by-step explanation:

Since we are told that a purse cost $75.00 at Macy’s with a 25% discount. The sale price will be:

= $75 - (25% × $75)

= $75 - (0.25 × $75)

= $75 - $18.75

= $56.25

We will then add the 7% tax and this will be:

= $56.25 + (7% × $56.25)

= $56.25 + (0.07 × $56.25)

= $56.25 + $3.9375

= $60.1875

Step-by-step explanation:

So, basically I can't remember how to do this the long way but I used a calculator on Desmos (the graphing one to be specific). You should be able to find tutorials on how to use it and graph problems to find their answers but if not, you can just message me and I'll walk you through how to use it.

As for the form it asked for in the question, slope-intercept form is just:

y = mx + b

m is the slope, and b is the y-intercept (the place where the line crosses the y-axis)

The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I will mark brainliest!

Answers

Answer:

Option 4

Step-by-step explanation:

Midpoint of the diameter is the center.

Use midpoint formula to determine the coordinates:

x = (2 - 4)/2 = -1y = (5 + 13)/2 = 9

Find the radius using the midpoint and one of the endpoints and the distance formula:

r = [tex]\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5[/tex]

Use the equation of the circle:

(x - (-1))² + (y - 9)² = 5²(x + 1)² + (y - 9)² = 25

A cashier at Giorgio's Grocery Store gets paid $8 per hour for shifts of 6 hours or less and $12 per hour for working shifts over 6 hours long. Which function best represents this situation?

Answers

Given :

A cashier at Giorgio's Grocery Store gets paid $8 per hour for shifts of 6 hours or less.

And $12 per hour for working shifts over 6 hours long.

To Find :

A function best represents this situation.

Solution :

Let, number of hours is h and amount paid is y .

For, h ≤ 6

y = 8h

For, h > 6

y = 12h

Therefore, function representing this is :

y( h ) = 8h , x ≤ 6

12h , x > 6

Hence, this is the required solution.
