1) 21 is 12.50% of 168.

2) 4% of 150 is 6.

3) 1% of 500 is 5.

4) 62% of 50 is 31.

5) 15% of 15 is 2.25

6) 40 percent of 25 is 10.

Step-by-step explanation:

1). 21 is what percent of 168.

Let,

x be the percent.

Therefore,

x% of 168 = 21

\frac{x}{100}*168=21

1.68x=21

Dividing both sides by 1.68

\frac{1.68x}{1.68}=\frac{21}{1.68}\\x=12.50

21 is 12.50% of 168.

2). What is 4 percent of 150.

4% of 150 = \frac{4}{100}*150

4% of 150 = \frac{600}{100} = 6

4% of 150 is 6.

3) 1 percent of 500 is what number

1% of 500 = \frac{1}{100}*500

1% of 500 is 5.

4) what number is 62 percent of 50

62% of 50 = \frac{62}{100}*50

62% of 50 = 0.62*50=31

62% of 50 is 31.

5) 15 percent of 15 is what

15% of 15 = \frac{15}{100}*15

15% of 15 = \frac{225}{100}=2.25

15% of 15 is 2.25

6) 40 percent of 25 is what number

40% of 25 = \frac{40}{100}*25

40% of 25 = \frac{1000}{100}=10

40 percent of 25 is 10.

(6) Give the equation of the line passing through the points (1,5) and (-2, 6) in
Bas_tet [7]

Answer:

⅓x + y = 5⅓

or

⅓x + y = 5.3333333

or

⅓x + y = 16/3

Step-by-step explanation:

Solve for slope using rise/run

Y2 - Y1 / X2 - X1

(6) - (5) / (-2) - (1)

1 / -3

Slope: -⅓

y = -⅓x + b

solve for b using one of the points

I'll be using (1,5)

Substitute the point into the equation

5 = -⅓(1) + b

5 = -⅓ + b (add ⅓ to both sides)

+⅓ +⅓

5⅓ = b

5⅓ can also be written as 16/3 or 5.333333

The equation is now:

y = -⅓x + 5⅓

Convert to standard form by adding ⅓x to both sides

y = -⅓x + 5⅓

+⅓x +⅓x

Solution: ⅓x + y = 5⅓

The percent of working students increased 21.7% to 8.9%, what was the percent prior to increase​
blagie [28]

Answer:

Approximately 7.3%.

Step-by-step explanation:

What is percentage increase?

\displaystyle \text{Percentage Increase} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100\%.

For this question:

  • \text{Percentage Increase} = 21.7\%,
  • \text{Final Value} = 8.9\% = 0.089, and
  • \text{Initial Value} needs to be found.

Let \text{Initial Value} = x.

\displaystyle \frac{0.089 - x}{x} = 0.217.

Assume that x \ne 0. Multiply both sides of the equation by x:

0.089 - x = 0.217x.

Add x to both sides of the equation:

0.089 = (1 + 0.217)x.

\displaystyle x = \frac{0.089}{1 + 0.217} = 0.0731 \approx 7.3\%.

In other words, the initial percentage is approximately 7.3%.

The graph of y=kcos(8x)
Firdavs [7]

The x coordinate of point A that is shown on the graph is 3π/16.

<h3>How to explain the graph?</h3>

From the information given, y = kcos(8x). Also, the axis of symmetry is given as kx.

Therefore, the x coordinate will be:

= π/8 + π/16

The LCM of 8 as 16 is 16.

= 2π/16 + π/16

= 3π/16
