Answer: 150 degrees

Reason: Vertically opposite angles are similar

(When two straight lines form an X when crossing over one another, an angle and the angle on the opposite side of the X are the same)

The measure of angle 8 is 150 degrees.

Opposite angles are angles that are found opposite each other. They are formed when two lines intersect. The value of a pair of opposite angles is equal.

It is given that angle 5 is equal to 150 degrees.

The image is also provided.

We can see that angles 5 and 8 are opposite angles.

We know that opposite angles have equal measures.

This means that the measure of angle 8 is the same as angle 5.

The measure of angle 5 is 150 degrees. Therefore, the measure of angle 8 is also 150 degrees.

We have found that the measure of angle 8 is the same as angle 5 which is 150 degrees since they are opposite angles.

Therefore, we have found that the measure of angle 8 is 150 degrees.

Answer:

228.8 meters

Step-by-step explanation:

y = -0.04 x² + 9.1 x + 11.9

When the rocket lands, y = 0:

0 = -0.04 x² + 9.1 x + 11.9

Solving for x, start by multiplying by -1:

0 = 0.04 x² - 9.1 x - 11.9

Multiply by 100:

0 = 4x² - 910 x - 1190

Solve with quadratic formula:

x = [ -b ± √(b² - 4ac) ] / 2a

x = [ 910 ± √((-910)² - 4(4)(-1190)) ] / 2(4)

x = [ 910 ± √(847140) ] / 8

x ≈ -1.3, 228.8

Since x can't be negative, x = 228.8 meters.

Answer:

The rocket will land at 208.02 m. Hence, if you are on the same connexus assignment, your answer will be A.

Answer:

[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

In calculating probability, remember that "AND" means "MULTIPLICATION" and "OR" means "ADDITION".

Since we want the probability of red necklace AND yellow bracelet, we calculate individual probabilities and "MULTIPLY" them.

Probability of red necklace:

There are 4 necklaces and 1 of them is red, hence probability of red necklace is 1/4

Probability of Yellow bracelet:

There are 2 bracelet and 1 of them is yellow, hence probability of yellow bracelet is 1/2

Now, we multiply both to get our answer.

1/4 * 1/2 = 1/8

Answer:

1/8

Step-by-step explanation:

Answer:

Actually it does relate to sin, cos and tan.

* tan50° = 16/b

=> b = 16/tan50° ≈ 13.426

* sin50° = 16/c

=> c = 16/sin50° ≈ 20.887

*cos∠B = 16/c = 16/20.887

=> m∠B ≈ 40.002

Answer:

106 m²

Step-by-step explanation:

Imagine this shape was a square, it's area would be 120 m².

Now imagine the little rectangle with 7 m as the side, you will have to work out the area of that so

Side = 7

4 + 4 + ? = 10

8 + ? = 10

? = 2

So the area of the little rectangle is 14 m²

Now we minus both of the areas : 120 - 14 = 106

Answer: c) (11,-2)

Step-by-step explanation:

The formula for calculate a midpoint is:

[tex]M=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

You know that R is the midpoint of segment PS and P is located at (8,10), and S is located at (12,-6). Then you can substitute these coordinates into the formula to find the coordinates of the midpoint R:

 [tex]M_{R}=(\frac{12+8}{2}, \frac{10+(-6)}{2})=(10,2)[/tex]

Now, knowing the coordinates of R and S, you can substitute them into the formula to find the coordinates of the midpoint Q of segment RS. Then:

[tex]M_{Q}=(\frac{10+12}{2}, \frac{2+(-6)}{2})=(11,-2)[/tex]

The option c is correct. The final coordinates of Q are (11, -2).

To find the coordinates of Q, we need to follow a step-by-step process, starting from the given points of P and S.

Step 1: Find the coordinates of R

R is the midpoint of segment PS. Given P(8,10) and S(12,-6), the midpoint formula is:

Midpoint formula: ((x1 + x2)/2, (y1 + y2)/2)

So, [tex]R = ((8 + 12)\div2, (10 + (-6))\div2) = (20\div2, 4\div2) = (10, 2)[/tex]

Step 2: Find the coordinates of Q

Q is the midpoint of segment RS. Given R(10,2) and S(12,-6), we apply the midpoint formula again:

[tex]Q = ((10 + 12)\div2, (2 + (-6))\div2) = (22\div2, -4\div2) = (11, -2)[/tex]

Final Coordinates:

Thus, the coordinates of Q are (11, -2). The correct answer is: (c) (11,-2)

Convert to pascals

72.7 atm=72.7*101,325=7,366,327.50 pascals

For this case we have the following functions:

[tex]f (x) = 2x ^ 2-18\\g (x) = - 3x-7[/tex]

We must find:

[tex](f-g) (2)[/tex]

By definition, we have to:

[tex](f-g) (x) = f (x) -g (x)[/tex]

So:

[tex](f-g) (x) = 2x ^ 2-18 - (- 3x-7)\\(f-g) (x) = 2x ^ 2-18 + 3x + 7\\(f-g) (x) = 2x ^ 2 + 3x-11[/tex]

Then, we evaluate in x = 2:

[tex](f-g) (2) = 2 (2) ^ 2 + 3 (2) -11\\(f-g) (2) = 2 (4) + 6-11\\(f-g) (2) = 8 + 6-11\\(f-g) (2) = 8 + 6-11\\(f-g) (2) = 3[/tex]

12.916/93=.13888172 dollars an hour.

.13888172(h)=m

Step-by-step explanation:i converted to decimals but its still the same

Hannah worked for a total of 7 11/12 hours and earned $93. She charges approximately $12 per hour, so the equation for the amount she earns is m = 12H.

To find out how much Hannah charges per hour, we first need to find the total number of hours she worked. Adding up the hours given, Hannah worked 1 1/4 + 2 1/6 + 1 1/3 + 3 hours = 7 11/12 hours. Since Hannah earned $93 for these hours, we can set up the equation, m = 93 / (7 11/12), where m represents the money Hannah earns per hour, and H represents the total number of hours Hannah worked. Upon solving this equation, we find that Hannah charges approximately $12 per hour.

Therefore, the equation that can be used to determine the money Hannah earns from walking the dogs is m = 12H.

Answer:

5^2 * 5^9

5^3 * 5^8

5^4 * 5^7

Step-by-step explanation:

The easiest way to approach this problem is to first express 5^(11) in its simplest form:

5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5

Then you can regroup them as you want, to still express the same value, but shown as a product of different numbers, including:

(5) * (5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5) = 5 * 5^(10)

(5 * 5) * (5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5) = 5^2 * 5^9

(5 * 5 * 5) * (5 * 5 * 5 * 5 * 5 * 5 * 5 * 5) = 5^3 * 5^8

(5 * 5 * 5 * 5) * (5 * 5 * 5 * 5 * 5 * 5 * 5) = 5^4 * 5^7

And so on....

Answer:

x = 12z + 1  and y = 10z - 1

Step-by-step explanation:

To solve the system of equations, we can use the substitution method

If we call

3x - 4y + 4z = 7 I

x - y - 2z = 2 II

2x - 3y + 6z = 5 III

Clearing II  x = 2 + y + 2z

Now, replacing II in III

2(2 + y + 2z) - 3y +6z = 5

4 + 2y + 4z - 3y + 6z = 5

10z - y = 1 from here y = 10z - 1

Finally, replacing y in I

3x - 4(10z - 1) + 4z = 7

3x -40z + 4 + 4z = 7

3x - 36z = 3

3x = 36z + 3

x = 12z + 1

Done

Use trigonometry.

cos(18°) = x/25

Multiply both sides by 25.

cos(18°)25 = x

23.7764129074 = x

We round off to the nearest hundredth. This means to round off to two decimal places.

Doing so, we get 23,78 cm = x.

Answer:

45 years

Step-by-step explanation:

First, lets break the problem down, step-by-step.

Jeremy's age can be represented using the varibale, j.

His father's age is 53, or 11 less than j squared.

Jeremy's father's age can be represented using the following equation:

j^2 - 11 = 53

Now, solve for j.

j^2 - 11 = 53

j^2 = 64

j = 8

That means Jeremy is 8 years old. Now, find the difference between his age and his father's age.

53 - 8 = 45.

So, Jeremy's father is 45 years older than his son.

I hope this helps! :)

To find how many years older Jeremy’s father is than Jeremy, we determined that Jeremy is 8 years old and his father is 45 years older than him. We did this by solving the equation derived from the problem statement. Thus, Jeremy's father is 45 years older than Jeremy.

To solve the problem, let's denote Jeremy's age by x. According to the problem, Jeremy’s father’s age is 11 less than Jeremy’s age squared. The given information states that Jeremy’s father is 53 years old.

We can write this as an equation:

[tex]x^2 - 11 = 53[/tex]

[tex]x^2 = 53 + 11[/tex]

[tex]x^2 = 64[/tex]

Taking the square root of both sides, we get:

x = 8

So, Jeremy is 8 years old. Now, to determine how many years older Jeremy’s father is than Jeremy:

53 (father's age) - 8 (Jeremy's age) = 45

Thus, Jeremy’s father is 45 years older than Jeremy.

Answer:

The area is

[tex]A=254.34\ in^2[/tex]

Step-by-step explanation:

The circumference of a circle is given by a following formula:

[tex]C = 2\pi r[/tex]

Where r is the radius of the circumference.

In this case we know that

[tex]C = 2\pi r=56.52\ in[/tex]

We solve the equation for r

[tex]C = 2\pi r=56.52\ in[/tex]

[tex]2\pi r=56.52\\\\r=\frac{56.52}{2\pi}\\\\r=9\ in[/tex]

The area of a circumference is given by the following formula

[tex]A=\pi r^2[/tex]

Now we substitute the value of r in the equation to find the area

[tex]A=\pi (9)^2[/tex]

[tex]A=3.14* (9)^2[/tex]

[tex]A=254.34\ in^2[/tex]
