Step-by-step explanation:

Given

the angle of elevation is $\theta =4^{\circ}$

Length of track is $L=387\ ft$

Vertical rise is given by

$\Rightarrow \sin (4^{\circ})=\dfrac{H}{387}\\\\\Rightarrow H=387\sin (4^{\circ})=26.99\approx 27\ ft$

The mean age of 9 women in an office is 27 years old. The mean age of 7 men in an office is 25 years old. What is the mean age (

marta [7]

Answer:

26 years

Step-by-step explanation:

Given:

The mean age of 9 women = 27 years old

The mean age of 7 men = 25 years old

Question asked:

What is the mean age (nearest year) of all the people in the office?

solution:

By using, mean = sum of observations divided by number of entities

The mean age of 9 women = 27 years old

$\frac{sum of ages}{number of women}$ = $27$

$Sum of ages of women = 27 \times9 = 243\\$ $years$

The mean age of 7 men = 25 years old

$\frac{sum of ages}{number of men}$ = $25$

$sum of ages of men = 25 \times7 = 175$

Total sum of ages of men and women in the office = 243 + 175

= 418 years

Total number of people in the office = 9 women + 7 men = 16

The mean age of all the people in the office = Total sum of ages of men and women in the office divided by Total number of people in the office

= $\frac{418}{16} = 26.125$

Therefore, the mean age (nearest year) of all the people in the office = 26 years

In Candyland, distance is measured in "lollygam" and "gumbo." Suppose there are 8.5 lollygam in a gumbo. Determine the number of

Alik [6]

Answer:

1.5225 gumbo squared

Step-by-step explanation:

First we know that 1 gumbo is equal to 8.5 lollygams.

To know the number of gumbo squared in 110 lollygam squared, we need to know the relation between 1 gumbo squared and 1 lollygam squared, and we do that making the square of our relation between gumbo and lollygams:

1 gumbo -> 8.5 lollygams

1 gumbo squared -> (8.5)^2 lollygams squared = 72.25 lollygams squared

Now, to know the number of gumbo squared in 110 lollygam squared, we just need to divide 110 by 72.25:

1 gumbo squared -> 72.25 lollygams squared

x gumbo squared -> 110 lollygams squared

x = 110/72.25 = 1.5225 gumbo squared
