The sizes of seven exterior angles of an octagon are: 42, 110, 13, 67, 55, 11 and 53. What is the size of the eighth exterior angle?
Answer:
9 degrees.
Step-by-step explanation:
For ALL polygons, the exterior angles add up to 360 degrees.
Therefore the 8th exterior angle = 360 - (42+110+13+67+55+11+53)
= 360 - 351
= 9 degrees.
Answer:
9°
Step-by-step explanation:
Always some of exterior angle of any polygon is 360
42 + 110 + 13 + 67 + 55 +11 + 53 + x = 360
351 +x = 360
x = 360 - 351
x = 9

Functions f(x) and g(x) are shown below:
f(x) = x2
g(x) = x2 - 8x + 1
In which direction and by how many units should f(x) be shifted to obtain g(x)? (1 poi
Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units
Answer:
f(x) should shifted Right by 4 units to obtain g(x) ⇒ B
Step-by-step explanation:
Let us put g(x) in the form of g(x) = (x - h)² + k, where h is the the horizontal shift (x - h) to right, (x + h) to left and k is the vertical shift (k) up and (-k) down
In the quadratic function y = ax² + bx + c, h = [tex]-\frac{b}{2a}[/tex] and k = y at x = h
∵ g(x) = x² - 8x + 1
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = -8
∵ h = [tex]-\frac{b}{2a}[/tex]
∴ h = [tex]-\frac{-8}{2(1)}=\frac{8}{2}[/tex]
∴ h = 4
∵ k = g(x) at x = h
- Substitute x by 4 in g(x) to find k
∴ k = (4)² - 8(4) + 1 = 16 - 32 + 1
∴ k = -15
- Substitute them in the form of g(x) = (x - h)² + k
∴ g(x) = (x - 4)² + (-15)
∵ h is the horizontal shift
∵ (x - h) means shift to right h units
∵ f(x) = x²
∵ g(x) = (x - 4)² + (-15)
- That means f(x) is shifted 4 units to the right
∴ f(x) should shifted right by 4 units to obtain g(x)

3 times a number plus 5 is the equal to the same number increased by 17. what is the number
Answer:
The number is 6
Step-by-step explanation:
Let the number be x
3 times a number plus 5 = 3x +5
Same number increased by 17 = x + 17
3x + 5 = x + 17
3x -x + 5 = 17
2x + 5 = 17
2x = 17 - 5
2x = 12
x = 12/2
x = 6
The solution to the problem 3x + 5 = x + 17 is x = 6. This involves setting up an algebraic equation using the given conditions and then solving for x.
Explanation:This problem seems to be a basic algebra problem. You can begin by setting up the equation based on the sentence given. The sentence translates into the equation: 3x + 5 = x + 17 where x is the unknown number you’re solving for. Then, you need to solve for x by isolating it on one side of the equation.
Step-by-step explanation: Subtract x from both sides of the equation to get 2x + 5 = 17. Then, subtract 5 from both sides to get 2x = 12. Finally, divide by 2 to solve for x. This will give you: x = 6. Therefore, the number that fits the condition in the problem is 6.

You leave your ranch in South Texas to drive your cattle to the railroad in Abilene, Kansas. You have 2,000 head of cattle and 10 cowboys (not including you.) Along the trail, you are attacked by some cattle rustlers, the herd stampedes during a thunderstorm, and you have trouble finding water. As a result, when you get to Abilene, you have lost 10% of the herd. You sell the cattle in Abilene for $35 a head. You pay each of the cowboys $100 and the rest of the money is yours. How much did you make?
Answer:
You get $5727.27
Step-by-step explanation:
At the start, you have 2000
After you are attacked, stampeded and have trouble finding water, you have lost 10% of your cattle
2000 * 10% is 200
2000 - 200 is 1800
Multiply 1800 cattle by $35 per cow
1800 * $35 = $63000
10 cowboys + 1 (you) is 11 people
Divide $63000 by 11
63000 / 11 = $5727.27
You get $5727.27

A randomly chosen quadrilateral has four right angles, has a probability that the quadrilateral also has four equal side lengths is 33%.
What is probability?Probability is a measure of the likelihood of an event to occur.
Many events cannot be predicted with total certainty.
We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Given is a Venn diagram,
In the Venn diagram, we can see that we have 9 elements, 6 of these belong to the set R, 3 of them belong to the set E, and 2 belong to both sets.
Now we want to find the probability that, if a figure has four right angles (belongs to R) it also has 4 equal side lengths (belongs to E).
So, given that an element belongs to R (6 elements there).
The probability that it also belongs to E,
2 out of these 6 elements belong to E, so the probability will be:
P = 2/6 = 1/3 = 0.33
To get this in percent form, we need to multiply it by 100%, we will get:
0.33x100% = 33%

Three ballet dancers are positioned on stage. Elizabeth is straight behind Hannah and directly left of Manuel. If Hannah and Elizabeth are 3 meters apart, and Manuel and Hannah are 5 meters apart, what is the distance between Elizabeth and Manuel?
Answer: Elizabeth and Manuel have a distance of 4 meters between them.
Step-by-step explanation: Please refer to the picture attached.
From the information given, Elizabeth is directly behind Hannah and directly left of Manuel. That means we have three points which are HEM, that is, we now have triangle HEM. The longest side (hypotenuse) which is the distance between Hannah and Manuel is given as 5 meters while the other side the distance between Hannah and Elizabeth is given as 3 meters.
We shall apply the pythagoras theorem in solving for the unknown side, EM.
The Pythagoras theorem states thus;
AC² = AB² + BC²
Where AC is the hypotenuse, and AB and BC are the other two sides.
Substituting for the known values, we now have;
5² = 3² + EM²
25 = 9 + EM²
Subtract 9 from both sides of the equation
16 = EM²
Add the square root sign to both sides of the equation
√16 = √EM²
4 = EM
Therefore the distance between Elizabeth and Manuel is 4 meters
Final answer:
To calculate the distance between Elizabeth and Manuel, the Pythagorean theorem is used. Given the 3-meter distance between Hannah and Elizabeth, and the 5-meter distance between Hannah and Manuel, the distance between Elizabeth and Manuel is calculated to be the square root of 34, which is approximately 5.83 meters.
Explanation:
The question pertains to finding the distance between Elizabeth and Manuel, given their respective positions on a stage in relation to Hannah.
To find the distance between Elizabeth and Manuel, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the distances between Hannah and the other two dancers form two sides of a right-angled triangle with Elizabeth and Manuel's positions marking the ends of the hypotenuse.
Since Hannah is 3 meters from Elizabeth and 5 meters from Manuel, we can calculate the distance between Elizabeth and Manuel (hypotenuse) with the following equation:
c^2 = a^2 + b^2
Where c is the distance between Elizabeth and Manuel, a is the distance between Hannah and Elizabeth (3 meters), and b is the distance between Hannah and Manuel (5 meters).
So, c^2 = 3^2 + 5^2 which simplifies to c^2 = 9 + 25, and further to c^2 = 34. This implies that c = [tex]\sqrt{34}[/tex].
Therefore, the distance between Elizabeth and Manuel is the square root of 34, which is approximately 5.83 meters. We can round this to the nearest hundredth for a precise measurement.
The distance between Elizabeth and Manuel is approximately 5.83 meters.

Explanation:Calculating Servings of LemonadeOscar and Eli have prepared 23 gallons of lemonade and want to know how many 1-cup servings they can sell. First, we need to know the equivalent of gallons to cups. There are 16 cups in 1 gallon. Therefore, we multiply 23 gallons by 16 cups per gallon to find the total number of cups available:
23 gallons x 16 cups/gallon = 368 cups. Thus, they can sell 368 1-cup servings of lemonade.
To summarize the conversion:
1. Identify the conversion rate between gallons and cups (1 gallon = 16 cups).
2. Multiply the total gallons of lemonade by the conversion rate to get the total cups (23 gallons x 16 cups/gallon).

The total number of combinations is 2000. Testing each one at a rate of 10 seconds per test would take approximately 20,000 seconds, which is around 6 hours when rounded to the nearest hour.
Explanation:This problem deals with the concept of combinations in mathematics. To find out how long it would take to try all possible combinations, you first need to determine how many combinations there are. The door code consists of either A or B (2 options) followed by a three-digit code (10 options for each digit, from 0-9). Therefore, there are 2 * 10 * 10 * 10 = 2000 possible combinations. If each combination takes 10 seconds to try, it would take 2000 * 10 = 20,000 seconds. To convert this to hours, divide by 3600 (as there are 3600 seconds in one hour), rounding to the nearest whole number, would give approximately 6 hours.

chick that hatched from it.
After plotting her results, Danila noticed that the relationship between the two variables was fairly linear, so she
used the data to calculate the following least squares regression equation for predicting the mass of the chick
from the breadth of the egg:
y = -47 + 2x
What is the residual of a 29 g falcon chick who hatches from an egg with a breadth of 40 mm ?
Answer:
residual = - 4
Step-by-step explanation:
The residual is the difference between the actual mass of the falcon chick and the mass our regression line would have predicted.
residual = actual mass - predicted mass
actual mass = 29 grams
The predicted mass of 40 mm breadth of egg can be calculated by using the regression equation Danila came up with.

What gives the range of the function y=|x-1|+7
The range of the function y=|x-1|+7 is all real numbers greater than or equal to 7, as the absolute value ensures non-negative values to which 7 is added.
The range of the function y=|x-1|+7 can be determined by analyzing the nature of the absolute value function and the constant term. The absolute value function, |x-1|, ensures that the output is always non-negative for any value of x, since it represents the distance from 1 on the number line, which cannot be negative. Therefore, when we add 7 to this non-negative value, the smallest value y can take is when |x-1|=0, which is when x=1. So, at x=1, y will be 7 since we have 0+7. For any other value of x, |x-1| will be positive, and when adding 7, y will be greater than 7. Hence, the range of y is all values greater than or equal to 7.

The expression 1.5t + 20 predicts the height in centimeters of a plant t days from today. What is the predicted height of the plant 15 days from today?
Answer:
42.5
Step-by-step explanation:
so you start with adding 15 to the equations because that is how many days
1.5 15 +20
1.5 x 15 =22.5
22.5+20=42.5
so 42.5 is the answer
The predicted height of the plant 15 days from today is 42.5 cm.
The given expression for the height of a plant is 1.5t + 20, where t represents the number of days from today. To find the predicted height of the plant 15 days from today, we need to substitute t = 15 into the expression.
Substitute t = 15 into the expression:height of the plant 15 days from today = 1.5(15)+20 cm
height of the plant 15 days from today = 22.5 + 20 cm = 42.5 cm
Therefore, the predicted height of the plant 15 days from today is 42.5 cm.

The general rule to reflect the coordinate across the x - axis is given by
[tex](x,y)\rightarrow (x,-y)[/tex]
Substituting the point A(-2,3), we get;
[tex](-2,3)\rightarrow (-2,-3)[/tex]
Thus, the coordinates of the point A' is (-2,-3)
Coordinates of the point B':
The general rule to reflect the coordinate across the x - axis is given by
[tex](x,y)\rightarrow (x,-y)[/tex]
Substituting the point B(0,3), we get;
[tex](0,3)\rightarrow (0,-3)[/tex]
Thus, the coordinates of the point B' is (0,-3)
Coordinates of the point C':
The general rule to reflect the coordinate across the x - axis is given by
[tex](x,y)\rightarrow (x,-y)[/tex]
Substituting the point C(-1,-1), we get;
[tex](-1,-1)\rightarrow (-1,1)[/tex]
Thus, the coordinates of the point C' is (-1,1)
Hence, the coordinates of the image after a reflection over the x - axis is A'(-2,-3), B(0,-3) and C(-1,1)
Answer:
A - (-2,-3)
B - (0,-3)
C - (-1,1)
