Answer:
Option 2: 
Step-by-step explanation:
Given:
From the triangle shown below;
A triangle QRS with angle QRS = 90°, ∠QSR = 30°.
Side QR = 5, SQ = 10 and RS = 5√3
Now, we know from trigonometric ratio that,

Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,

Therefore, the value of sine of 30° is one-half. So, second option is correct.
For multiplication, if both integers have like signs, it is always positive. If they have unlike signs it is negative.
For division, if both integers have like signs it is positive. If they have unlike signs it is negative.
To find the answer, you have to make a proportion. 210 out of 700, or 210/700 is equal to x/100. So, 210/700=x/100. Then to solve the proportion, you must cross multiply. 210 times 100 is 21,000. Then, you must divide 21,000 by 700, which is 30. The 30 represents 30/100, which is 30%
The answer is 30%.
Answer:
2=2
Step-by-step explanation:
Answer:
13/4
Step-by-step explanation:
Convert these numbers to a mixed fraction.
-5 3/4 => -23/4
-2 1/2 => -5/2
Make them have a common denominator
-5/2 => -10/4
-23/4 can stay the same.
To find the distance between the two numbers, subtract the lesser value from the greater value.
-23/4 is <u>less</u> than -10/4.
(-10 - (-23)) /4
= 13/4
Therefore the distance between -2 1/2 and -5 3/4 on a number line is 13/4.
