The three angles together form a 180 degrees angle.

So, the equation would be

$29+Z+112=180$

we can sum the numbers on the left hand side:

$Z+141=180$

and subtract 141 from both sides:

$Z=180-141=39$

Answer:

39°

Solution and Explanation:

The reason why the answer is 39 degrees is because those three angles are on a 180 degree angle. So adding the two angles up and subtracting it by 180 will give you the third missing angle.

112 + 29 = 141

180 - 141 = 39

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except -3. Which

Maurinko [17]

Answer:

The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Step-by-step explanation:

As the domain of f(x) is the set of all real values except 7. So it can be written as follows:

Domain of f(x) = { x ∈ R | x ≠ 7}

As the domain of g(x) is the set of all real values except -3. So it can be written as follows:

Domain of g(x) = { x ∈ R | x ≠ -3}

It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.

So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

When randomly selecting an adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U

bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.

$P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

The probability of an event tells the chances of happening of that event.

It is mathematically defined as:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Complement of an event:

It is the event that consist of all outcomes not happening in A.

It is represented by $\bar{A}$

$P(A) + P(\bar{A}) = 1$

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) $P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.

If ABCD is dilated by a factor of 2 the coordinate of b would be? Will mark barinlyist.

ch4aika [34]

Answer:

B'(- 2, 2 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is

B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar

MaRussiya [10]

Answer:

4 stacks of packages

4 * 4 = 16 pieces of pancake

Step-by-step explanation:

Maximum amount to spend ≤ $30

Milk chocolate = $3.25

Pancakes per stack = 5.50 (sold in stacks of 4)

Let number of stacks = s

In equality terms :

3.25 + 5.50s ≤ 30

5.50s ≤ 30 - 3.25

5.50s ≤ 26.75

s ≤ 26.75 / 5.50

s ≤ 4.86

Hence, 4 stacks of pancakes can be purchased
