$4 is what percent of $50?

Answers

4 is what percent of 50?

P% = 4/50
p = 0.08

From decimal to percent:

P% = 0.08 * 100 = 8%

you turn $4 out of $50 into 4/50 and multiply by 2 therefor 8%

35. an open circle means there is no equal sign, and shading to the left means less then...so inequality is : x < 6

36. a closed circle means there is an equal sign, and shading to the left means less then.... x < = 9

in short...a closed circle means there is an equal sign, an open circle means there is not. if it is shaded to the left, it is less then...if it is shaded to the right, it means it is greater then.

Which of the following equations have exactly one solution?Choose all answers that apply:
~
A) 6x – 6 = 15x + 15
B) 6x – 15 = 6x +15
C) 6x – 6 = 6x + 15
D) 6x + 15 = 6x + 15

Answers

Final answer:

By assessing each equation, we deduce that the only equation that has exactly one solution among the ones given is equation A (6x – 6 = 15x + 15). Equations B (6x – 15 = 6x +15) and C (6x – 6 = 6x + 15) have no solutions, and equation D (6x + 15 = 6x + 15) has infinitely many solutions.

Explanation:

Solution to an equation is the value of variable that satisfies the equation or makes the equation true. Let's examine the given equations one by one:

A) 6x – 6 = 15x + 15: If we simplify this equation by moving all the terms involving x to one side and the constants to the other, we get: 9x = -21, which gives x = -21/9 or -7/3, hence this equation has exactly one solution .

B) 6x – 15 = 6x +15: In this case, if we subtract 6x from both sides, we get -15 = 15, which is not true, hence this equation has no solution.

C) 6x – 6 = 6x + 15: Again, if we subtract 6x from both sides, we get -6 = 15, which is not true, hence this equation again has no solution.

D) 6x + 15 = 6x + 15: For this equation, it stands true for any value of x, therefore this equation has infinitely many solutions.

So, out of the given options, only the equation A has exactly one solution.

A shop sells newspapers for a profit of 0.5%. His sales for the month of January were $8341.50. How much of this is profit?

Answers

Amount of sales of newspapers for the month of January = $8341.50
Percentage of profit for which the newspaper is sold = 0.5%
Then
Amount of profit made in the month of January = 0.5% * 8341.50 dollars
   = (0.5/100) * 8341.50 dollars
   = 4170.75/100 dollars
   = 41.707 dollars
   = 41.71 dollars
So the shop makes a profit of $41.71 in the month of January by selling newspapers worth $8341.50. I hope the procedure is perfectly clear for you to understand.
