Answer:

x = 70

Step-by-step explanation:

The angle between the tangents is the supplement of the intercepted arc:

x° = 180° -110°

x° = 70°

Alternate solution

The exterior angle x° is half the difference of the intercepted arcs. Long arc ACB is 360° -110° = 250°, so we have ...

x° = (250° -110°)/2 = 140°/2

x° = 70°

If you work this alternate solution generically, you find it is the same as the first solution.

x = ((360 -AB) -AB)/2 = (360 -2AB)/2 = 180 -AB

What is an expression?

In mathematics, an expression is a combination of numbers, variables, operators, and/or functions, which can be evaluated or simplified. Expressions can be simple, such as a single number or variable, or complex, involving multiple operations and variables.

We can begin solving the problem by translating the given sentence into an equation:

"Twice a number, n, added to 13 is equal to 55"

2n + 13 = 55

Next, we can isolate the variable n on one side of the equation by subtracting 13 from both sides:

2n = 55 - 13

2n = 42

Finally, we can solve for n by dividing both sides of the equation by 2:

n = 21

Therefore, the value of the number n is 21.

Step-by-step explanation:

since they are three consecutive numbers, label the first number x, the second x+1, and the third x+2. set up an equation by adding them and setting them equal to 90 as shown below:

x+(x+1)+(x+2)=90

then, solve the equation:

3x+3=90

3x=87

x=29

x+1=30

x+2=31

The integers are 29, 30, and 31.

A game of chance involves rolling a 16-sided die once. If a number from 1 to 3 comes up, you win 4 dollars. If the number 4 or 5 comes up, you win 7 dollars. If any other number comes up, you lose. If it costs 5 dollars to play, what is your expected net winnings

Answers

Answer:

-$1.8

or loss of $1.8

Step-by-step explanation:

Given the following parameters, we have

The probability of winning $4 is 3/16

The probability of winning $7 is 2/16

The probability of losing $5 is 11/16

E(X) = (4 * 3/16) + (7 * 2/16) + (-5 * 11/16)

= 12/16 + 14/16 - 55/16

= -29/16

= -1.8

Hence, your expected net "winnings" would be -$1.8. That's an expected loss of $1.8.

Step-by-step explanation:

Use the appropriate formula from your list of area and volume formulas.

Area of a Cone

A = πr(r +h) . . . . . where r is the radius and h is the slant height

The radius is half the diameter, so is 4 inches.

A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²

Consider the following pair of equations:
y = x + 4
y = −2x − 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. There is no pic pls help xd

Answers

Answer:

x is equal to -2, and y is equal to 2.

Step-by-step explanation:

You can solve this type of question by solving one of the equations for a given variable, and substituting it into another.

Because both of these are definitions of y, we could simply say, y = y, and thus:

x + 4 = -2x - 2

3x = -6

x = -2

This tells us also that y, being equal to x + 4, must equal 2

We can find the same solution by solving one of them for x, then substituting that into the other. We know:

y = x + 4

so we can also say:

x = y - 4

If we substitute that into the other:

y = -2x - 2

y = -2(y - 4) - 2

y = -2y + 8 -2

3y = 6

y = 2

which we can then plug into either of the original equations to solve for x:

y = x + 4

2 = x + 4

x = -2
