Use the sin identity to find that side.  Sin(30) = a/12...12 sin(30) = a, and a = 6

Can u pls help me with this question asap ​
serg [7]

Answer:

Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)

So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year

Step-by-step explanation:

Use the proportions from earlier

We have the point (5, 21000)

70,000/21,000 = 3.3

To find the x-value multiply 3.3 by 5

3.3 * 5 = 16.65

We can even use the other point's values to find the exact same answer

Point (3.5, 14700)

70,000/14,700= 4.7619047619

4.7619047619 * 3.5 = 16.66 (literally about the same)

You download 12 news songs to your phone. Then you delete 5 old songs.Write each amount as an integer.
Gennadij [26K]
Hey there! :D

When you have a value, it is usually positive.

For example, if I have 5 chocolate bars, then I have +5 chocolate bars. 

When you take away a value, it is usually negative.

For example, I have 3 chocolate bars away, then I would have 3 fewer chocolate bars. (-3) 

Integers are negative or positive whole numbers.

12 songs= 12 <== the integer

Delete 5 old songs= -5 <=== the integer

I hope this helps!

It’s a little complicated but here’s how it works:
Imagine a table with the intervals
0:4 , 4:6 , 6:7 , 7:10 , 10:13 (10 year intervals)
Then we have different rows
Class width: 4 , 2 , 1 , 3 , 3
Freq density: 0.2 , 0.5 , 1.2 , 0.7 , 0.3
So now calculate frequency where freq = class width * density
Freq: 0.8 , 1 , 3.6 , 2.1 , 0.9
So to find median find cumulative frequency
(Add all freq)
Cfreq = 8.4 now divide by 2 = 4.2
So find the interval where 4.2 lies.
0.8 + 1 = 1.8 + 3.6 = 5.6

So 4.2 (median) will lie in that interval 60-70 years.

A 10-ft vertical post casts a 14-inch shadow at the same time a nearby cell phone tower cast a 119-ft shadow. How tall is the ce
Yakvenalex [24]

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

1.167x = 10*119

x = \frac{1190}{1.167}

x = 1020

The cellphone towers height is 1020 ft.
