Two sides of an obtuse triangle measure 10 inches and 15 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side?

Answers

Answer 1
Answer: Answer – 19 inches
 The smallest possible whole-number length of the longest side of an obtuse triangle is the next integer greater than the Pythagorean distance of the other two sides.
 Given,
A = 10
 B = 15
Pythagoras theorem;
C^2 = A^2 + B^2
C^2 = 15^2 + 10^2
C^2 = 225 + 100
C^2 = 325
C = 18.03
 Therefore, the smallest possible whole-number length of the longest side is the next integer greater than 18.03 inches.
The smallest possible whole-number length of the longest side is 19 inches

Step-by-step explanation:

Which of the following is true? A Tangent is positive in Quadrant I. B Sine is negative in Quadrant II. C Cosine is positive in Quadrant III. D Sine is positive in Quadrant IV.

Answers

Answer:  The correct option is (A) Tangent is positive in Quadrant I.

Step-by-step explanation:  We are given to select the correct statement from the options provided.

The rule of signs for the trigonometric ratios in the four quadrants are as follows :

Quadrant I :    All the three ratios, tangent, sine and cosine are positive.

Quadrant II :   Only sine is positive, cosine and tangent are negative.

Quadrant III :  Only tangent is positive, sine and cosine are negative.

Quadrant IV :  Only cosine is positive, sine and tangent are negative.

Therefore, using the above rules, we can say that the options (B), (C) and (D) are incorrect.

Option (A) is correct because all the ratios are positive in Quadrant I and so is tangent.
The true statement in that a tangent is positive in quadrant I.

A share of stock in the Bree Medical Supply Company is quoted at 35 1/4 . Suppose you hold 20 shares of that stock, which you bought at 31 1/2. If you sold your stock at 35 1/4, which of the following would be true?

Answers

If you will sell the 20 stocks you will gain $75 or $3.75 per stock. This is computed as follows:

35 1/4 - 31 1/2; 35.25 - 31.5 = 3.75
=3.75 x 20
=$75

Chang 0.83 into a fraction

Answers

answer: 83/100

there you go!!!!

Hope it helps

Create a “fraction” with 0.83 in the numerator and 1.0 in the denominator:

0.83/1.0

Move the decimal point in 0.83 two places to the right to turn it into a whole number; move the decimal point in the denominator the same number of places. Do this one decimal place at a time:

0.83/1.0=8.3/10.0=83/100

At this point, you can drop the decimal points and trailing zeros in both the numerator and denominator.
