The only way I know to do this is with the cos law

y^2 = x^2 + z^2 - 2*x*z cos(Y)

x = 22

z = 16

y = ?

I have serious doubts that this will make a triangle. I ran it though a calculator and it does work -- surprise for me. Substitute the givens.

y^2 = 256 + 484 - 2*10*22*cos(13)

y^2 = 740 - 704*cos(13)

y^2 = 740 - 704*0.9744

y^2 = 740 - 685.95

y^2 = 54.05 Take the square root of both sides

y = √54.05

y = 7.351

Answer:

7.4

Step-by-step explanation:

The information given is in from SAS.

This is a job for law of cosines.

This is the law of cosines $a^2=b^2+c^2-2bc cos(A)$

The angle A is opposite side a and b,c are the other sides.

So 13 degrees is opposite the y there.

$y^2=16^2+22^2-2(16)(22)\cos(13)$

Now I'm going to put 16^2+22^2-2*16*22*cos(13) in my calculator:

$y^2=54.04347439$

Now one more step. To get rid of the square, you need to square root both sides:

$y=√(54.04347439)=7.351426691$

Sp the answer is approximately 7.4

you should do 5 times 12 plus the 3 it's better to do multiplication it's easier but if you divide that is ok but the dividing is more work

i think the correct answer is 5 hope i helped

How do you count by ones from 368 to 500 change for a larger unit when necessary

Answers

500 - 368 = 132
This means that to reach 500 from 368, you will need to count 132 ones.

132 can be written in several ways including:
132 = 100 + 32
132 = 100 + 30 + 2

For the first one:
the count will be 1 one hundred and 32 units to reach 500 from 368

For the second one:
the count will be one hundred, 30 tens and 2 ones to reach 500 from 368

In order to reach a count of $500$ from $368$ we need to count $\fbox{\begin\n\ \bf 132 \text{one's}\n\end{minispace}}$ .

Further explanation:

The problem is based on counting.

As per the International Numeral System the first digit is at one's place, second digit is at ten's place, third digit is at hundred's place.

In any number each digit has its place value and a face value.

Face value of any digit is its actual value of the digit.

For example: In a number $234$ the face value of the digit $4$ is $4$ and the face value of the digit $3$ is $3$ .

Place value of any digit in a number is the value represented by the digit as per the position of the digit in the number.

For example: In a number $234$ the place value of the digit $4$ is $4$ , place value of the digit $3$ is $30$ and the place value of the digit $2$ is $200$ .

In this question it is asked to determine a way to count by one's from $368$ to $500$ .

The difference between the number $368$ and $500$ is calculated as follows:

$\fbox{\begin\n\ 500-368=132\n\end{minispace}}$

The number $132$ is read as one hundred and thirty two.

The number $132$ is represented as follows:

$\fbox{\begin\n\ 132=100+30+2\n\end{minispace}}$

This implies that the digit $2$ is at one's place, digit $3$ is at ten's place and the digit $1$ is at hundred's place.

From figure 1 (attached in the end) it is observed that $10$ unit of one’s is equivalent to $1$ unit of ten's and $10$ unit of ten's is equivalent to $1$ unit of hundred's.

So, as per the above statement it is concluded that to reach a count of $500$ from $368$ we need to count $132$ one's.

Thus, in order to reach a count of $500$ from $368$ we need to count $\fbox{\begin\n\ \bf 132 \text{one's}\n\end{minispace}}$ .
