Suppose that in circle with center P, and a central angle, ∠OPQ, intersects minor arc OQ, where the measure of arc OQ = 82◦, and the measure of ∠OPQ is (5x – 3) ◦. What is the value of x?

Answers

Answer 1

Answer:

Central Angle OPQ = Arc OQ = 82°

5x - 3 = 82°

5x = 85°

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Give 1/2 a cup to a dog that weighs 25 lb

Step-by-step explanation:

Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol)  :)

10 lb = ⅙ Or 0.1666666 cups

1 lb = ? cups

\(\frac{0.16}{10}\) = 0.01666666

1 lb = 0.01666666 cups

25 lb = 0.01666666 × 25 cups

25 lb = 0.416666667 Or \(\frac{5}{12}\) cups

(Or:      10lb= ⅙              20lb= ⅙+⅙ = \(\frac{2}{6}\)              5lb= ⅙ ÷ 2= \(\frac{1}{12}\) (10lb÷2)       25lb = \(\frac{1}{12}+\frac{2}{6}\) = \(\frac{5}{12}\) ≈ 0.416666667     (25=20+5)

When we cross-multiply 1 and 3/5, we get 5 = 3

When we cross-multiply 4/3 and 1/2, we get 8 = 3

20=21 ≠ 5=3 ≠ 8=3

Explain why the relationship is proportional.How does the equation represent constant of proportional?

Answers

Answer:When two things are proportional, they always change together at the same rate. This relationship can be represented by an equation like y = kx, where k is a constant number that shows how the two things are related.

Step-by-step explanation:

Two quantities are proportional if they always change at the same rate. For example, if you travel at a constant speed, your distance is proportional to your time. If you double your time, you double your distance.

We can represent proportional relationships with an equation of the form y = kx, where y is one quantity, x is the other quantity, and k is a constant of proportionality.

The constant of proportionality k represents the factor by which one quantity changes for a given change in the other quantity. For example, if your speed is 60 mph when you travel 10 miles, the constant of proportionality is 6, which means your speed increases by 6 mph for each additional mile you travel.

To find the constant of proportionality k, you can divide any value of y by the corresponding value of x. For example, if you know that when x = 2, y = 8, then k = y/x = 8/2 = 4.

The equation y = kx can be used to predict one quantity if you know the other quantity. For example, if you know that y = 24 when x = 6, you can use the equation to find k = y/x = 24/6 = 4, and then predict that y = kx = 4*8 = 32 when x = 8.

because if the relationship between equations has an x before the equals sign we can then differentiate between the two. first take the first number of the left equation and same on the right. multiply them and times it by pi. then take out the odd numbers and you are left with your final equation.

Answer:

X intercept is (-8,0), Y intercept is (-6,0)

Step-by-step explanation:

The intercept is where the line crosses the X and Y axis, so in this line, the line crosses the x axis at (-8,0) and the y axis at (-6,0).

Answer:

There are two different intercepts in this linear line. The x - intercept would be at (-8, 0), and the y - intercept would be at (0,-6). To find out which is the x - intercept and which is the y - intercept, remember that x is always horizontal and y is always vertical.
