This is a part:part ratio. to answer the question, we need to change it into a part:whole ratio. to do this we add up the parts to equal 7. so the ratio of girls to students is 3:7. divide 238 (whole) by 7 (whole) to equal 34. now we multiply 34 by 3 for girls and by 4 for boys. girls: 102; boys: 136.

What is the percent of change in 6 yards to 36 yards
BaLLatris [955]

Answer:

The percent of change in 6 yards to 36 yards is 500% .

Step-by-step explanation:

Formula

Percentage = \frac{Change\ in\ value\times 100}{initial\ value}

Where

Change in value = Final value - initial value

As given

The percent of change in 6 yards to 36 yards.

Final value = 36 yards

initial value = 6 yards

Change in value = 36 - 6

                           = 30 yards

Put in the formula

Percentage = \frac{30\times 100}{6}

Percentage = \frac{3000}{6}

Percentage = 500%

Therefore the percent of change in 6 yards to 36 yards is 500% .

The board of directors of Midwest Foods has declared a dividend of $3,500,000. The company has 300,000 shares of preferred stock
FinnZ [79.3K]

Answer:

  1. $855,000
  2. Dividend per share of common stock = $1.06

Step-by-step explanation:

1. Preferred Share dividends.

There are 300,000 preference shares and each of them got $2.85. Total dividends are;

= 300,000 * 2.85

= $855,000‬

2. Total dividends = $3,500,000

Dividends left for Common Shareholders (preference gets paid first)

= 3,500,000 - 855,000

= $2,645,000

Common shares number 2,500,000

Dividend per share of common stock = \frac{2,645,000}{2,500,000}

= $1.06

What is the measure of angle x, In degrees?<br><br> Helps please!!
Mars2501 [29]
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.

All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40

Final answer: D
