Remark

A cyclic quadrilateral is one whose vertices touch the circumference of a circle. It has the strange property that opposite angles add up to 180 degrees. "b" is opposite a 110o angle. Therefore b = 180 - 110 = 70 degrees.

Answer B

Hi!

So because the quadilateral is inscribed in a circle then opposing angles of that quadilateral are supplementary (that means they add up to 180°).

Since the angle opposite to b is 110°, then the measure of b is 70°.

b + 110° = 180°
b = 70°

The answer is B.

For what value of a does (1/9)a+1 =81a+1 272-a?

AlexFokin [52]

Answer:

-4

Step-by-step explanation:

$\left( \dfrac{1}{9}\right)^{a+1}= 81^{a+1}\cdot 27^{2-a}\\\\\\(3^{-2})^{a+1}=(3^4)^{a+1}\cdot (3^3)^{2-a} \\\\\\3^{-2a-2}=3^{4a+4}\cdot 3^{6-3a} \\\\\\3^{-2a-2}=3^{a+10} \\\\\\-2a-2=a+10 \\\\\\-3a=12 \\\\\\a=-4$

Hope this helps!

The number of candies in bags of the same size is normally distributed with a mean of 145 candies and a standard deviation of 3

Virty [35]

Answer:

<u>The correct answer is A. 109</u>

Step-by-step explanation:

1. Let's review all the information given to answer the question correctly:

Mean of candies in bags = 145

Standard deviation = 3

Number of bags of candies on a shelf = 160

2. About how many bags of candies are expected to have between 142 candies and 148 candies?

Let's recall that in a normal distribution, the 68.2% of the sample or the population is between minus one and plus one time the standard deviation.

For our case, the 68.2% of the bags of candies are expected to have between minus one time the standard deviation (145 - 3) and plus one time the standard deviation (145 + 3).

<u>It means that 109 bags (0.682 * 160) are expected to have between 142 and 148 candies. The correct answer is A. 109.</u>

Miguel paid a total of $12,000 for stock that was $8 per share. If he sold all his shares for $15,000, how much profit on each s

Scorpion4ik [409]

If you would like to know how much profit on each share did he make, you can calculate this using the following steps:

$12,000 / $8 = 1,500 shares

$15,000 / 1,500 shares = $10 per share

x% of $8 is $10
x/100 * 8 = 10 /*100/8
x = 10 * 100 / 8
x = 125%

125% - 100% = 25%

Miguel made 25% ($2) profit on each share.
