We can use trigonometry.  The cosine of 15 will be the side adjacent to the 15-degree side (the one we are looking for) divided by 20, the hypotenuse.  As cos(15) is about .966, we get 19.32 as the side we are looking for.

ollegr [7]
The numbers that are divisible by 3 are:

3, 6, 9, 12, 15, 18, 21, 24
that is 8 numbers divisible by 3

24-8=16 numbers NOT divisible by 3

so the probability of not picking a number divisible by 3 is 16/24


hope this helps and is right :)

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3 3, negative 1 over 2, −1.
Mars2501 [29]

Answer:

Option 4 - -1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}

Writing all number in one form,

\frac{1}{5}=0.2

-\frac{1}{2}=-0.5

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

-1.4

So, -1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3

Therefore, option 4 is correct.

Jenna has a savings account invested in stocks and bonds. 20% of her savings is in bonds. If Jenna has $2,200 in bonds, how much
VladimirAG [237]

Answer: Her total savings are equal to $11,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation.

The total savings (x) multiplied by the percentage in bonds (in decimal form) must be equal to $2,200.

Mathematically speaking:

x (20/100) = 2,200

Solving for x:

x = 2,200/ 0.2

x = $11,000

Her total savings are equal to $11,000.

Feel free to ask for more if needed or if you did not understand something.
