if you want to multiply mixed numbers you need to turn them into improper fractions
Answer:
145
Step-by-step explanation:
Its the opposite angle of 145
For this problem plug in the given x and y values:
For the first one: No
second one: No
third one: Yes
fourth one: No
Answer: Last option.
Step-by-step explanation:
In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.
You can observe that Sergei's first step was to round 149% and 67 up, getting this result:

To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:
Therefore, we can conclude that<em> the estimate is greater than the actual answer because the percent and the number were both rounded up</em>.
Answer:
<u>The correct answer is C. 129.</u>
Step-by-step explanation:
Let's recall that the Inscribed Quadrilateral Theorem states that a quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary.
In the case of the inscribed quadrilateral ABCD in the graph attached, we have that:
m∠C= 51°, therefore its supplementary angle, ∠A, should be the difference between 180° and m∠C.
m∠C= 180° - m∠A
Replacing with the real values:
51 = 180 - m∠A
m∠A = 129°
<u>The correct answer is C. 129.</u>
