Answer:
120º
Step-by-step explanation:
angles of an equilateral triangle are equal so..
180 ÷ 3 = 60º
to get the exterior m⦣C
180 - interior m⦣C = exterior m⦣C
180º - 60º = 120º

what is the mean of the set of numbers please explain case I don't get it
A 5 feet
B 5 feet 1 inch
C 5 feet 2 inches
D 5 feet 3 inches
E 5 feet 4 inches
F 5 feet 5 inches
Answer:
Add up all of the numbers in the set and then divide by how many numbers there are.
Step-by-step explanation:
I'm not sure if that's the most conventional way- but it's how I learned.
Here's your set of numbers:
4'11, 5'0, 5'0, 5'1, 5'2, 5'2, 5'3, 5'4, 5'4, 5'4, 5'4, 5'4, 5'5, 5'5, 5'6
And here's that same set of numbers in inches (which is what I'd use to find it out):
59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66
Which adds up to a total number of 15 numbers in the set.
Add up 59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66.
That's 943.
Then we divide 943 by how many numbers there are in the set (15).
The mean of your set is 62.8666667.
Round to the nearest whole number, making it 63.
How many feet is 63 inches?

Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?
Answer:
What I would tell Gareth is that his prediction is somewhat right because there is a 50/50 chance of landing the coin on each side because 410 is half of 820.

Task 10: It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate:
How many pounds of mashed potatoes can they make with 15 pounds of potatoes?
Answer:
The answer is 22.5 lbs or 22 and a half lbs of mashed potatoes.
Step-by-step explanation:
The ratio of potatoes is 1.5.
10 lbs potatoes * 1.5 = 15 lbs mashed
So 15 lbs potatoes * 1.5 is: 22.5 lbs mashed potatoes.

Use the elimination method to solve the following system of equations:
2x+y=3
3x – y= 12
The solution is
x = 3
y = -3
(3, -3)
Step-by-step explanation:
Choose one of the equations and isolate y. I will use the first one.
2x + y = 3
Y = 3 - 2x
Now sub the solution for y into the equation below.
3x - y = 3
3x - (3 - 2x) = 12
3x - 3 + 2x = 12
5x - 3 = 12
5x = 15
x = 3
To get y, sub the answer for x into one of the equations.
2(3) + y = 3
6 + y = 3
y = 3 - 6
y = -3
Answer:
(x,)y) =(3,-3)
Step-by-step explanation:
add the equations vertically to eliminate one variable
2x +y = 3
3x -y = 12
5x =15 divide both sides by 5
x = 3 now substitute the given value of x into the equation 2x+y=3
2 x 3 + y = 3 multiply 2x3
6 +y =3 move constant to the right
y = 3-6
y = -3

Answer:
6 lines of symmetry
Step-by-step explanation:
This is a 6 sided polygon which is known as hexagon.
Now, line of symmetry of this hexagon is a line that passes through the centre of it and thereby divides it into equal parts.
Now, we can see the short lines on each side of the hexagon. When they are extended to join a similar line on the opposite face, they all pass through the centre.

A 10% increase followed by another 10% increase is not the same as a total increase of
20%.
What is the total percentage increase?
Answer:
21%
Step-by-step explanation:
Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.
Answer:
21%Step-by-step explanation:
Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.
Let's do the maths…
Let's start with 100 to make things easy.
We know that 10% of 100 is 10.
We know that 20% of 100 is 20.
So if we increase 100 by 10% we get 110.
If we increase 100 by 20% we get 120.
Now lets do the 10% plus 10%.
From the first 10% increase we were left with 110.
Now if we take 10% of the 110 we have 11.
Add that to the 110 and we get 121.
This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.

41/19 as a decimal rounded to the nearest hundredth
The decimal rounded to the nearest hundredth is 2.16
What is Decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.
Given:
41/19
Now, dividing the fraction
41/19
= 2.1578
Now, rounding off to nearest hundredth focus on thousandth place value whether it is greater than 5 or not.
Hence, the decimal rounded to the nearest hundredth is 2.16

2 = one place value
1 = tenth place value
5 = hundredth place value
7 = thousandth place value
8 = ten thousandth place value.
The value of 41/19 as a decimal rounded to the nearest hundredth is 2.16.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,

A teacher offers gift cards as a reward for classroom participation. The teacher places the gift cards from four different stores into a bag and mixes them well. A student gets to select two gift cards at random (one at a time and without replacement). Each outcome in the sample space for the random selection of two gift cards is equally likely. What is the probability of each outcome in the sample space?
1/16
1/6
1/4
1/2
Answer:
its either 1/4 or 1/16. i havent done this in forever.. so i cant figure out which one it is. go with your gut feeling, but i think its 1/4
Answer:
The answer is D. 1/2
Step-by-step explanation:
Because the probability of getting each gift card is 1/4. So since the student picks it without replacement, this means that we're multiplying 1/4 X 1/3 which would equal 1/12. Now we multiply 1/12 by 6 because there are six different variations of getting the cards. This would give us 6/12 or 1/2.

The profit p gained from selling an item can be modeled by a quadratic function in terms of its cost c. If the cost of the item is at $100 or $400, there will be no profit or loss. But if the cost is $250, the item generates the maximum profit of $30.
Answer:
Uh I'm not really sure how to screenshot on my laptop, but the answer should be B.
Step-by-step explanation:
Lets say I made a graph, P being profit C being cost.
P
50|___|___|___|___|___|
40|___|___|___|___|___|
30|___|___|___|___|___|
20|___|___|___|___|___|
10 |___|___|___|___|___|C
0___100|200|300|400|500
It goes from 100 (LOW) to 400 (HIGH). 250 being the the cost of the item, and the maximum profit being 30. Cost 250,0__Profit 0,30. In all 250,30.
Therefore whatever the letter answer is they might be shuffled, do the one that most compares to this formula.
