What’s the area of this circle?

Answer:

CXXVI is in roman number

Answer:

c. 15

Step-by-step explanation:

20 - 15 + 5

35 - 15(2)

35 - 30 = 5

Answer: C(x) = 13x +95​

Step-by-step explanation:

Here's the remainder of the question:

If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost? A C(x)=95x – 13 B C(x)=13x – 95 C C(x)=95x +13 D C(x)=13x +95​

Based on the information given in the question, the total cost will be:

= 95 + 13(x)

= 95 + 13x

Therefore, the correct answer will be C(x)=13x +95​

Here are the points and a graph showing the dilation in purple

Answer:

30

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

We use the formula y2-y1/x2-x1. The two points that I would use are (3,-1) and (-3,-3). This means that the equation will be -3--1/-3-3. This is equal to -2/-6. This is also equal to 1/3. Therefore, the slope is 1/3.

Answer: you have to divide each side by 8, not 4. If you divide by 4, you get 2x = 1

The correct answer would be 1/2

Answer:

14

Step-by-step explanation:

ACQ, (According to the question)

x=10

2x - 8

What we have to do is, we have to substitute the value of x with the equation's x, so,

=> 2* 10 - 8

=> 20 - 8

=> 14

Hope it helps :)

Answer:

1/4

Step-by-step explanation:

Possible outcomes from rolling the cube that satisfy the "greater than 3" criterion are {4, 5, 6}  out of a total of six possibilities {1, 2, 3, 4, 5, 6}.  Thus, the probability of rolling a number greater than 3 is 3/6, or 1/2.

Probability of flipping heads is 1/2.

These are entirely independent events.  Thus, the joint probability is (1/2)(1/2), or 1/4.

Answer:

The answers are A, B and C.

Step-by-step explanation:

To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57

Next Divide 21 on both sides. -57/21 is -36

You should have -3k > -57

Divide -3 on both sides. -57/-3 is 12

You should end up with k > 12

And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

Answer:

1st one: 1/12

2nd one: 1/14

3rd one: 1/7

Step-by-step explanation:

Find period (Just count how much it takes for the graph to repeat again)

1st one: 12

2nd one: 14

3rd one: 7

Frequency = 1/period

1st one: 1/12

2nd one: 1/14

3rd one: 1/7

Answer:

d

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

D

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Answer:

x=6

Step-by-step explanation:

x+54+5x=90

6x+54=90

6x=36

x=6

Answer:

x=6

Step-by-step explanation:

So, lets go over what we know.

Angle 5x and angle x+54 make up 90 degrees.

We know its 90 degrees since there is a square like symbol on the side of the line.

To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.

So:

5x+x+54=90

=

6x+54

Now that we combined our two angles, we can solve it like a normal equation:

6x+54=90

subtract 54 from both sides to get 6x alone:

6x=36

Now divide both sides by 6 so x is alone:

x=6

So now we know that x=6.

If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:

Angle 5x:

5*6

=

30

Angle x+54

6+54

=

60

Add the two angles together:

30+60

=

90

So we have checked and the answer is still correct!

Hope this helps! :D

Answer:

22in²

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Circumference = 25 (1/7)

As we know,

Circumference of a circle = 2πr

By solving this we get

Radius (r) = 4in

Now. we can calculate the area by using following formula,

Area  = πr²

By putting the value, we get

Area = (22/7) × 4²

=  22/7 × 16

= 352÷16

Area = 22in²

Answer:

The derivative of the function is:

[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]

Step-by-step explanation:

The first principle is given by:

[tex]f'(x)=\frac{dy}{dx}=lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex]

The function here is:

[tex]f(x)=x+\frac{1}{x}[/tex]

Now, using the first principle we have:

[tex]f'(x)=lim_{h\rightarrow 0}\frac{(x+h)+\frac{1}{(x+h)}-x-\frac{1}{x}}{h}[/tex]  

[tex]=lim_{h\rightarrow 0}\frac{h+\frac{1}{(x+h)}-\frac{1}{x}}{h}[/tex]    

[tex]=lim_{h\rightarrow 0}\frac{h-\frac{h}{x(x+h)}}{h}[/tex]    

[tex]=lim_{h\rightarrow 0}\frac{h(1-\frac{1}{x(x+h)})}{h}[/tex]

[tex]=lim_{h\rightarrow 0}1-\frac{1}{x(x+h)}[/tex]

[tex]=1-\frac{1}{x^{2}}[/tex]

Therefore, the derivative of the function is:

[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]

Answer:

4L-12

Step-by-step explanation:

let's assume the length = L

then the width of the rectangle is L - 6

perimeter = 2× (a+b)

where "a" and "b" are the length and the width of the rectangle.

so perimeter = 2× (L + L - 6)

2 × ( 2L - 6)

4L - 12

Answer: [tex]\frac{1}{a^6}[/tex]

Step-by-step explanation:

When you want to solve something that has a negative exponent, turn it into a fraction.

a^-6

= [tex]\frac{1}{a^6}[/tex]

If you knew the value of a, you would solve it completely.

Answer:

The 3rd one is correct

(7.5 + 3) x 6 - 4)

Answer:

False

8 rows of seats are needed to fit all students

Step-by-step explanation:

Total students at the theater = 56

Number of seats per row = 7

Number of rows = 7

Total seats in the theater = Number of seats per row * Number of rows

= 7 * 7

= 49 seats

Rows of seats needed to fit all of the students is not 7 because the students are more than the number of seats in the theater.

Therefore,

8 rows of seats are needed to fit all students

Total seats in the theater = Number of seats per row * Number of rows

= 7 * 8

= 56 seats

Answer:

192 ft²

Step-by-step explanation:

Area of rectangular backyard = 1248 ft²

Width of backyard = 52 ft

Length = x

Area of rectangular backyard = Length * width

1248 = x * 52

x = 1248 / 52

x = 24 feets

Hence, x = height of triangular garden

Area of triangle = 1/2 base * height

Area = 1/2 * 16 * 24

Area = 192 ft²
