Answer:

a) See figure attached

b) x = \frac{sin(124)}{sin(34)} 80.086 = 118.732 ft

c) h = 35 sin (59) = 30.0 ft

So then the heigth for the building is approximately 30 ft

Step-by-step explanation:

Part a

We can see the figure attached is a illustration for the problem on this case.

Part b

For this case we can use the sin law to find the value of r first like this:

\frac{sin(22)}{35 ft} =\frac{sin(59)}{r}

r= \frac{sin(59)}{sin(22)} 35 ft = 80.086ft

Then we can use the same law in order to find the valueof x liek this:

\frac{sin(124)}{x ft} =\frac{sin(34)}{80.086}

x = \frac{sin(124)}{sin(34)} 80.086 = 118.732 ft

And that represent the distance between Sara and Paul.

Part c

For this cas we are interested on the height h on the figure attached. We can use the sine indentity in order to find it.

sin (59) = \frac{h}{35}

And if we solve for h we got:

h = 35 sin (59) = 30.0 ft

So then the heigth for the building is approximately 30 ft

Eva8 [605]

Answer:

D. unfavorable fixed overhead flexible minus budget variance

Step-by-step explanation:

As the cost of the equipment is increasing the fixed efficiency and idle capacity variance would be unfavorable resulting in an  unfavorable fixed overhead flexible minus budget variance.

The expenses of the machinery are the fixed indirect costs which result in fixed overhead variances. Since it is related to the working of the machinery it would result in efficiency and idle capacity variances that in turn would give unfavorable fixed overhead of the flexible minus budget variance.

IXL!! I WILL ADD BRAINLIST!
klio [65]

Answer:

-3,3.1, 3 2/10

Step-by-step explanation:

When you are putting different numbers from least to greatest, you need to put them in the same form...

First things first we should put -3 wayy up front. negative numbers are worth less than positive numbers.

Then we need to turn 3 2/10 into a decimal.

3 2/10 -------> 3.2

3.2 is more than 3.1

Thus, the order is

-3,3.1, 3 2/10

Hope this helps and have a nice day.

liraira [26]

Answer:

$3,300

Step-by-step explanation:

$60,000 falls into the $50,001 - $100,000 range, so 5.5% is owed on it.

5.5% → 0.055

60,000 * 0.055 = $3,300
