Answer:

69

Step-by-step explanation:

The central angle is twice the inscribed angle. So the angle that is behind the one equal to 2x is equal to x. We know that the opposite angles in a circle add up to 180. Therefore, we can solve for x:

[tex]x + x + 42 = 180$^{\circ}$\\\\2x = 180$^{\circ}$ - 42$^{\circ}$\\\\2x = 138$^{\circ}$\\\\x = 69$^{\circ}$[/tex]

The solution for the equations is at x = -1 and y = -3.

2: the system of equations has the same slope and the same y-intercept so the system of equations has infinitely many solutions.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given the equations,

-2x + 4y = -10

2x + 2y = -8

adding both the equations so -2x and +2x will be eliminated

-2x + 4y + 2x + 2y = -10 - 8

6y = -18

y = -18/6

y = -3

substitute the value of y in equation 2x + 2y = -8

2x + 2(-3) = -8

2x = -8 + 6

x = -1

2: Given equations y = -x + 5 .........(1)

y + x = 5 .........(2)

equation 2 can be written as,

y = -x + 5

so both the equations have the same slope and the same value of y-intercept,

There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.

Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.

Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.

Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.

If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.

Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.

Therefore, there are 32 fingers / 8 fingers/row = 4 rows of Soprano.

The logarithm of a number with respect to a base is the exponent to which the base must be raised to produce that number. In other words, log_b(x) = y means b^y = x.

To find log_7(x), we can use the change of base formula which is log_b(x) = log_c(x) / log_c(b).

So you can use the logarithm of base 10 (common logarithm) or base e (natural logarithm) and use the above formula to find log7

So for example, log7(49) = log10(49) / log10(7) or log7(49) = ln(49) / ln(7)

What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

Given that stamp of Height is 3in with 4 1/2 in width.

So 9/2 of width = 3 Height

1 of width = 3/(9/2) Height

The multiplication theorem of probability is if  and  be two events associated with the sample space . Then, (∩) = ()⋅() and the addition theorem of probability is For two mutually exclusive events ,

(or ) = () + ().

According to the multiplication theorem of probability, the probability of both events and occurring is equal to the product of the probability of occurring and the conditional probability of event occurrence if event happens.

Let  and  are two events associated with the sample space . ∩ gives the simultaneous occurrence of two events  and

We know that the conditional probability of the event given that has occurred is given by (∣) and is given by

(∣) = (∩)(), () ≠ 0

We can write the above equation as

(∩) = (∣)⋅()⋯()

Also, we can write

(∣) = (∩)(), () ≠ 0

(∩) = (∣)⋅()

Combining () and (), we can write

(∩) = (∣)⋅() = (∣)⋅(), where (),() ≠ 0

According to the addition theorem, if two events and , are mutually exclusive, the probability of either or  occurring is the total of the individual probabilities of  and .

Let event happen in ways, and event happen in ways. Then the total number of happening of events is , which is = +

Thus, the probability of events happening is given by (or ).

By the definition of probability,

() = / and () = /

Adding,

() + () = / + / = + / = / = 1

(a) The net force equation on q1 is 10.6N towards q2. (b) The acceleration of q1 would be 6.8x10^7m/s^2.

a) The Coulomb's law equation for the force between two charges q1 and q2 is given by:

F = k(q1q2)/r2

Where k is the Coulomb's constant and r is the distance between the two charges.

Using this equation, the force on q1 due to q2 can be calculated as:

F12 = (8.99x109 N m2/C2)(8.00x10-6C)(-5.00x10-6C)/(1.00m)2

F12 = -44.8x10-6 N

Similarly, the force on q1 due to q3 can be calculated as:

F13 = (8.99x109 N m2/C2)(8.00x10-6C)(5.00x10-6C)/(2.00m)2

F13 = 55.2x10-6 N

The net force on q1 can be calculated as the vector sum of F12 and F13:

F1 = F12 + F13

F1 = 10.6N towards q2

b) The acceleration of q1 can be calculated using Newton's second law of motion:

F = ma

a = F/m

Where m is the mass of q1.

Therefore, the acceleration of q1 can be calculated as:

a = (10.6N)/(1.50g)

a = 6.8x107m/s2

Explanation:

There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).

This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.

The 6 different combos are shown in  list 2  

List 1 is not correct because you can choose one vegetable only, and not have both.

Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.

We arrive at the probability 2/6 = 1/3

The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.
