Eight less than four times a number is less than 56. What are the possible values of that number?

Answer:

159°

Step-by-step explanation:

Angle 21° and <4 are supplementary angles!

21 + x = 180

x = 159°

Hope this helps!

The measure of angle ∠4 is 159.

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

From the figure,

The angle opposite to 21° and ∠4  sum is 180.

This means,

Angles on the same side.

Now,

Opposite angles are equal.

So,

21 + ∠4 = 180

∠4 = 180 - 21

∠4 = 159

Thus,

The measure of angle ∠4 is 159.

sample size is the number of individuals in the sample and the sample is 60 guests.

Step-by-step explanation:

She wants to find out the food preferences for the guests, so she surveys 60 guests and discover 45 of those guests prefer chicken and 15 prefer fish.

The sample is 60 guests.

To find the slope, we must have two points

   --> Two points: (-3,1) and (-1, -5)

The square of 2 plus the prime number 13 add up to 17

[tex]2^{2}+13=4+13 =17[/tex]

Hope this helps

Answer:

Square number = 4

Primer number = 13

Step-by-step explanation:

A square number is the result when a number has been multiplied by itself.

A prime number is a whole number greater than 1 that only has two factors, itself and 1.

List all the square numbers and prime numbers below 17:

Square numbers: 1, 4, 9, 16, ...

Prime numbers: 2, 3, 5, 7, 11, 13, ...

Therefore, the only combination of square number and prime number that sums to 17 is:  4 + 13 = 17

Solution

Square number = 4

Primer number = 13

Answer: Choice E

[tex]x \ne -4, -1[/tex]

This is the same as saying [tex]x \ne -4 \text{ and } x \ne -1[/tex]

======================================================

Reason:

If we plugged x = -4 into the function, then the x+4 in the denominator turns to 0.

x+4 = -4+4 = 0

Dividing by zero is not allowed. It leads to a division by zero error. Therefore, we need to exclude -4 from the domain. Similar reasoning will exclude -1 as well because it makes the x+1 in the denominator to be zero.

Any other x value is valid.

Side note: The (x+1) terms cancel, which may appear that x = -1 is valid. However, your calculator will likely not perform such a simplification. It will simply try to directly compute the result using PEMDAS. That means x = -1 is likely to produce a division by zero error.

Answer: Most likely it is A

Step-by-step explanation:

Although it should be B, because a non linear function doesn't  have a rate of change. I already looked up this question many times so we know It's NOT C.

The best modeled by a nonlinear function with time as the independent variable is:

The value of a collectible baseball card that increases by a constant factor of 1.1, or by 10%, each year.

A nonlinear function is one that does not follow a straight line.

In this case, t

A) describes a linear function since the value of the gift card decreases by a fixed amount each month, resulting in a straight-line relationship.

B) describes a constant value, which is a special case of a linear function where there is no change over time.

C) The value of the collectible baseball card increases by a constant factor of 1.1 each year, which results in exponential growth. This behavior is best modeled by a nonlinear function.

D) describes a linear function since the value of the investment increases by a fixed amount each week, resulting in a straight-line relationship.

Answer:

Below in bold.

Step-by-step explanation:

tan 150 = -tan 30

= -1/√3 = y/x    (1)

This is a unit circle so the hypotenuse = 1.

so sin 150 = y/1 = y

y = 1/2

So substituting in equation (1)

1/2 / x =  -1/√3

-x = √3/2

x = -√3/2.

The value of x in the unit circle is -√3/2.

Option B is the correct answer.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

Since the angle is 150 degrees, we know that it is in the second quadrant, where the x-coordinate is negative and the y-coordinate is positive.

Since the circle has a radius of 1, the y-coordinate is sin(150) = 1/2.

To find the x-coordinate, we can use the formula x = cos(θ), where θ is the angle in radians.

To convert 150 degrees to radians, we multiply by π/180:

150 degrees x π/180 = 5π/6 radians

So,

x = cos(5π/6) = -√3/2.

Therefore,

The value of x is -√3/2.

Step-by-step explanation:

Marcel made an error which is both terms aren’t multiplied by 8x, so 8x can’t go in front of the parentheses" option (A) is correct.

The distributive property is the property that expresses the distributive law of algebraic multiplication. Similarly, in polynomial expression we can use the distributive property, for example, we can write a(c+b)  in the form of (ac+bc).

The expression is:

= 8x(4) - 2(8)

= 8(4x - 2)

The error is "both terms aren’t multiplied by 8x, so 8x can’t go in front of the parentheses"

Answer:

Ted has 10 books and Omar has 15 books

Step-by-step explanation:

Hey there!

In order to find how many books each of the boys have, we can make a system of equations

First equation: O+T=25

Second equation: O=2T-5

After making the equations, you can use substitution by plugging in 2T-5 For O in the first equation:

2T-5+T=25

Simplify LHS

3T-5=25

Take 5 to the other side

3T=30

Divide by 3 on both sides to get T by itself

T=10

So this means that Ted has 10 books

Now we can plug this into the second equation

*note that you can plug 10 into the first equation too*

O=2(10)-5

Simplify RHS

O=20-5

Combine like terms

O=15

This means that Omar has 15 books

So, Ted has 10 books and Omar has 15 books

Based on the amounts that Jack invested into the different investment vehicles, the amount Jack earns a year would be $1,132.87.

The amount invested is:

= 2 / 3 x 15,000

Amount after a year:

= Amount x e ^ (rate x time)

= 10,000 x e ⁰.⁰⁸ ˣ ¹

= $10,832.87

Amount invested:

= 1/3 x 15,000
