Solve for the value of x and y

Answer:

? = 60

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

120 = ? +60

subtract 60 from each side

120-60 = ? +60-60

60 = ?

Answer:

n+1

Step-by-step explanation:

h(n) = 4n + 5

g(n) = 3n +4

(h - g)(n) = 4n + 5  - (3n +4 )

distribute the minus sign

              = 4n +5 - 3n -4

Combine like terms

              = 4n -3n  +5-4

               = n +1

Answer:

The standard deviation from the mean is the square root of the variance.

Therefore, SD = sqrt(VAR) = sqrt(36) = 6

Answer:

A.

Step-by-step explanation:

Given: limit of f(x) exists at x = a

To choose: the correct option

Solution:

A limit is a value that a function approaches as the input approaches some value.

[tex]\lim_{x\rightarrow a}f(x)=L[/tex] means that as x approaches to value a then f(x) approaches to value L.

A limit of a function f(x) exists at x = a if [tex]\lim_{x\rightarrow a^-}f(x)=\lim_{x\rightarrow a^+}f(x)=L[/tex]

So, option A. is correct.

Answer:

A.

I took the quiz and got it correct.

Answer:

see below

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi (5)^2

A = 25 pi

Using 3.14 for pi

A = 78.5 ft^2

Using the pi button

A =78.53981634 ft^2

Answer:

x = -3

In-Depth Steps:

1.) Start with the bottom equation: [tex]x+2y=-3[/tex]

2.) Set [tex]x[/tex] alone on one side of the equal sign. Your equation will look like [tex]3+2y=x[/tex].

3.) Plug [tex]3+2y[/tex] in for [tex]x[/tex] in the first equation. You will get [tex]2(3+2y)+5y=6[/tex].

4.) Distribute. Your equation now looks like this: [tex](6+4y)+5y=6[/tex].

5.) Combine like terms. You will get [tex]6+9y=6[/tex].

6.) Subtract 6 from both sides. You get [tex]9y=0[/tex]. We can learn that Y=0.

7.) Go back to either equation and put 0 in for y.

8.) In the top equation, it would look like [tex]2x=6[/tex] and the bottom equation would look like [tex]x=-3[/tex]. We basically got our answer of [tex]x = -3[/tex], but we will plug it into the [tex]2x=6[/tex] equation, and in-fact, we get x = -3.

Answer:

f(1) = 93

f(n) = f(n - 1) + 4

Step-by-step explanation:

The recursive formula for an arithmetic sequence is given as:

f(1) = a

f(n) = f(n - 1) + d

where a = first term and d = common difference

An arithmetic sequence is in the form:

f(n) = a + d(n - 1)

where a = first term and d = common difference

The common difference in f(n) = 93 + 4(n-1) is 4.

The first term is 93.

The recursive formula is therefore:

f(1) = 93

f(n) = f(n - 1) + 4

Answer:

f(1)=93

f(n)=f(n-1)+4

Step-by-step explanation:

As you can see in the picture, the initial value is 93, which is why it's the first part of the equation. The 4 is multiplying the (n-1) part in the equation and as we complete the recursive formula of N, you have to put the numbers in the correct order.

Answer:

(7 x 5) + (7 X 3) = 7 X 8 or (7 x 4) + (7 X 4) = 7 X 8

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

=> the total cost = the total number of people * the ticket cost each

= 7 X 8

Hence, he can use this way to break apart the array to find the product:

(7 x 5) + (7 X 3) = 7 X 8 or (7 x 4) + (7 X 4) = 7 X 8

Hope it will find you well.

Step-by-step explanation:

Answer:

Anna's number could be 5 and it could be 6.

Step-by-step explanation:

Let Anna's number be represented by x.

If Bill squared her number followed by subtracting 11 times her number, and adding 4, then he would get -26.

This implies that:

[tex]x^2 - 11x + 4 = -26[/tex]

This is a quadratic equation and we can solve for x by factorization.

[tex]x^2 - 11x + 4 = -26\\\\=> x^2 - 11x + 4 + 26 = 0\\\\x^2 - 11x + 30 = 0\\\\x^2 -6x-5x + 30 = 0\\\\x(x - 6) - 5(x - 6) = 0\\\\(x - 5) (x - 6) = 0\\\\[/tex]

=> x = 5 and x = 6

Anna's number could be 5 and it could be 6.

Answer:

x=4

Step-by-step explanation:

4(3x+5)=6(x+8)-x

Distribute

12x +20 = 6x +48 -x

Combine like terms

12x+20 = 5x+48

Subtract 5x from each side

12x-5x +20 = 5x-5x+48

7x +20 = 48

Subtract 20 from each side

7x+20-20 = 48-20

7x = 28

Divide each side by 7

7x/7 = 28/7

x = 4

Answer:

[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]

So then the distance between the submarine and the airplace is 525 m

Step-by-step explanation:

For this case we know that the submarine is 150 m below the sea level and the airplane is 375 m above the sea level and we want to find the difference between the heights and we got:

[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]

So then the distance between the submarine and the airplace is 525 m

Answer:

The slope of the line is 1

Step-by-step explanation:

To figure out the slope, you just have to do rise over one, if the line is going up from left to right then the slope is positive, which is the case shown

Answer:

[tex]28\sqrt{2}[/tex]

Step-by-step explanation:

To answer this question, you must split 98 into 2 factors:

                                                      98

                                                 2          49

                                                          7       7

2 and 49 can be multiplied to get 98. 49 is also a perfect square, meaning the factors are going to be the same number, which is 7. Since there are two 7's you take that out of the radical, like so:

[tex](7)4\sqrt{2}[/tex]

[tex]28\sqrt{2}[/tex]

Answer:

5, 12, 13

Answer:

Arc length of Semicircle ⇒ 5π

Step-by-step explanation:

See procedure below;

Radius of Semicircle ⇒ 5 units,

Diameter of Semicircle ⇒ 2 * 5 = 10 units,

Now if we were to imagine a complete circle, the length of this arc would be half of the circumference of the complete circle provided it ∈ to a semicircle. Therefore, if we are to calculate the length of the circumference of the complete circle given the diameter to have a length of 10, we can divide this by two to receive the arc length of the semicircle;

Circumference of Complete Circle ⇒ πd ⇒ 10π,

Arc length of Semicircle ⇒ 10π / 2 = 5π;

Answer; Arc length of Semicircle ⇒ 5π

Answer:

2*10^-4

Step-by-step explanation:

Answer:

2.0x10^6

Step-by-step explanation:

First, let's change the number in the numerator into scientific notation.

180/ 9.0x 10^-5 = 1.80x10^2/ 9.0x10^-5

Start by collecting the significance and exponents.

1.80X10^2/ 9.0x10^-5 = 1.80/ 9.0x 10^2/10^-5

Then divide each term separately. When dividing exponents with the same base, subtract their power.

=0.20x10^2-(-5) =0.20x 10^7

To write the answer correctly in scientific notation, the first number needs to be between 1 and 10. In this case, we need to move the decimal one position to the right without changing the value of our answer.

We can use the fact that 0.20 is the same as 2.0/10, or 2.0x 10^-1

=2.0x10^-1x 10^7

=2.0x 10^-1+7

=2.0x 10^6

Answer:

Either 36.35 or 16.00173

Answer:

The population density is 7592 people per square mile

Step-by-step explanation:

The population density of los Angeles here refers to the number of people present by square miles

Mathematically, to find this population density, what we need to do is to divide the total population that we have by the area of Los angeles

The population here is 4,000,000 while the area is 503 square miles

The population density is thus ;

4,000,000/503 = 7592.29 which is approximately 7592 people per square mile
