Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.
What is the Alternate Interior Angles Theorem?If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.
What are Angles on a Straight Line?Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.
Given the following:
m∠BFC = 75°
m∠GFC = 38°
∠EFB, ∠BFC, and ∠GFC are angles on a straight line, therefore:
m∠EFB = 180 - m∠BFC - m∠GFC
Plug in the values
m∠EFB = 180 - 75 - 38
m∠EFB = 67°
Find the measure of angle FBC:
Angles FBC and EFB are alternate interior angles, therefore:
m∠FBC = m∠EFB = 67° [alternate interior angles theorem]
m∠FBC = 67°
In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

There are 3 urns containing coins. Urn I contains 5 gold coins, urn II contains 2 gold coins and 2 silver coins, and urn III contains 3 silver coins. An urn is selected at random and a coin is drawn from the urn. If the selected coin is silver, what is the probability that urn III was selected? (Enter your probabilities as fractions.)
2/3 is the probability of selecting silver coin from Urn III.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Urn I: 5 gold coins
Urn II: 2 gold coins and 2 silver coins
Urn III: 3 silver coins
The probabilities of choosing an urn are calculated as shown below:
P(Urn1)+P(Urn2)+P(Urn3)=1/3
First, calculate the probability of choosing a silver coin from the first urn.
P(S1)=0/5
Now, calculate the probability of choosing a silver coin from the second urn.
P(S2)=2/4=1/2
Now, calculate the probability of choosing a silver coin from the third urn.
P(S3)=3/3=1
Now, calculate the probability that the silver coin is selected from Urn III.
P(Silver coin chosen from urn III)=Favorable outcome/Total outcome
=1/3×1/1/3×0+1/3×1/2+1/3×1
=1/3/(1/6+1/3)
=2/3
Hence, the probability of selecting silver coin from Urn III is 2/3.

Find the number of successes x suggested by the given statement. A running shoe manufacturer randomly selects 386 of its shoes for quality assurance and finds that 3.12% of these shoes are found to be defective. A. 12 B. 374 C. 120 D. 3
To find the number of successes x, we need to first find the total number of defective shoes. To do this, we can multiply the total number of shoes selected for quality assurance by the percentage of defective shoes, expressed as a decimal: 386 shoes * 0.0312 = 12.0736. Since we cannot have a fraction of a shoe, we can round down to the nearest whole number to find the number of successes x: 12.0736 rounded down = 12. Therefore, the number of successes x is 12, and the answer is 12.

You and a friend go to Tacos Galore for lunch. You order three soft tacos and three
burritos and your total bill is $11.25. Your friend's bill is $10.00 for four soft tacos
and two burritos. How much do soft tacos cost? How much do burritos cost?
please show work
Answer:
3 tacos and 3 burritos cost $11.25; 4 tacos and 2 burritos cost $10. The difference is 1 more taco and 1 less burrito, for $1.25 less.
So adjust the order repeatedly the same way, adding one taco and taking away one more burrito, and decreasing the cost by $1.25 each time.
3 tacos, 3 burritos, $11.25
4 tacos, 2 burritos, $10.00
5 tacos, 1 burrito, $8.75
6 tacos, 0 burritos, %7.50
The cost of each taco is $7.50/6 = $1.25.
3 of each cost $11.25, so 1 of each cost $3.75; the taco costs $1.25, so the burrito costs $2.50.
ANSWERS: taco $1.25, burrito $2.50

The slope of the line in the function is 1
Slope of LineThe slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
m = y₂ - y₁ / x₂ - x₁
Taking two points;
P = (5, 0)Q = (3, -2)Substituting the values into the formula;

cos (x + 16) = sin(3x – 2)
Answer:
x = 19
Step-by-step explanation:
So cos and sin are closely related, but they are not equal. In order for these two to be equal to each other, the angles (in the parenthesis by the cos and by the sin) have to be complementary. That is, they have to add up to 90°
Use this idea to set up an equation.
x + 16 + 3x - 2 = 90
Combine like terms.
4x + 14 = 90
Subtract 14.
4x = 76
Divide by 4.
x = 19
x = 19
If you are kooking for the angles:
x + 16
= 19 + 16
= 35
and
3x - 2
= 3(19) - 2
= 57 - 2
= 55
Check: 35 + 55=90
Also,
cos35 = sin55

6 is the least common denominator found by multiplying 3 by 2
what is the discontinuity of f(x) = the quantity of 4 x squared minus 16, all over 2 x minus 4
The function given as f(x) = (x² - 16)/(6x - 24) is discontinuous at x = 4
What is the discontinuity of the function?We are given the function as;
f(x) = (x² - 16)/(6x - 24)
We have to find the discontinuities of the function.
Now, the denominator 6x - 24 becomes 0 when x = 4.
This means that when x = 4, the function now becomes undefined.
Therefore, we can say that there is a discontinuity at x=4
However, this discontinuity can be removed due to the fact that we have x = 4 in the numerator.
But despite the above, it is still discontinuous at that value of x.

The volume of liters equivalent to a 2/3 serving shown using the proportional relationship displayed on a double number line is 4 liters
What is a number line?A number line consists of numbers spread in equal increments or spacing on an horizontal or vertical line.
The volume equivalent to 1/4 serving = 3/2 liters
A volume of 3/2 liters = 1.5 liters

Answer:
It is not possible to determine the dimensions of a rectangle with only the information that its area is 2/9. The area of a rectangle is calculated by multiplying its length by its width, so a rectangle with an area of 2/9 could have many different combinations of length and width. For example, a rectangle with dimensions of 1/3 by 2/3 would have an area of 2/9, as would a rectangle with dimensions of 2/9 by 1.

What is the proportional relationship?Relationships between two variables that are proportional occur when their ratios are equal.
Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value.
The "constant of proportionality" is the name of this constant.
So, consider the tables as follows:
