First off, you must have a calculator to find any cos,sin, or tan.
tangent of 39 degrees is .80978
rounding to the nearest ten thousandth would be .8098 because the 8 in the hundred thousandths is greater than 5.

One day it snowed 3 and 3/8 inches in Altoona and 3.45 inches in Bethlehem. Which city received less snow that day?
Ksivusya [100]

Answer: Altoona.

Step-by-step explanation:

You know that in that day it snowed  3\ \frac{3}{8}\ inches in Altoona.

Given this measurement as a mixed number, you need to convert it to a decimal number. Then:

3\ \frac{3}{8}\ inches=(3+ \frac{3}{8})\ inches=(3+0.375)\ inches=3.375\ inches

It that day it snowed  3.45\ inches in Bethlehem.

Then, you can notice that:

3.375\ inches

Therefore, you can conclude that the city that received less snow that day was: Altoona.

Which of the following is a correct interpretation of the expression -7- (-11)?
Brilliant_brown [7]

Answer:

B. Start at -7 on the number line and move 11 to the right.

Step-by-step explanation:

<u>Given:</u>

  • - 7 - (-11) expression

We can add or remove only positive numbers on the number line to get it  correct, so we need to open the parenthesis. When evaluated we get:

-7- (-11) = - 7 + 11 = 4

<u>Correct interpretation of of this expression is:</u>

  • Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.

<u>Correct choice is:</u>

  • B. Start at -7 on the number line and move 11 to the right.

a ABC company stock dropped from 25 3/8 to 22 1/4 during a one month period of time so how much stock fall during this period of
OLEGan [10]
First, let's convert the mixed fraction into an improper fraction (trust me, mixed fraction are pretty much the worst things to deal with, especially with higher level math):
25 \frac{3}{8} =  \frac{203}{8}
22 \frac{1}{4} =  \frac{89}{4}

Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:
2 (\frac{89}{4} ) =  \frac{178}{8}

Now that we have a common denominator, we are ready to subtract:
\frac{203}{8} -  \frac{178}{8} =  \frac{25}{8}

Since that's the most simplified form, and you have been asked the question in a mixed fraction form, let's convert that to a mixed fraction. The remainder of the numerator divided by the denominator is 1, and the quotient is 3. The denominator stays the same. So, this is what results:
3 \frac{1}{8}

And that's your answer: 3 \frac{1}{8}

Hope this all makes sense. If anything doesn't, feel free to tell me!
