Calculate the 4th angle of a quadrilateral if the other sides are 56, 115 and 120.
Answer:
69°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the given angles from 360, that is
4 th angle = 360° - (56 + 115 + 120)° = 360° - 291° = 69°
in your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you were getting dressed, and you can’t see the color of the socks. How many socks must you pick to absolutely guarantee that you have a pair of blue socks to wear?
A.) 14
B.) 24
C.) 4
D.) 3
E.) 2
Answer:
A. 14
Step-by-step explanation:
The smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A)
What is pigeonhole principle?If there are n objects to be putted into m containers such that n > m, then at least one container will have two objects.
Suppose the worst is happening when you're pulling the socks out.
The total number of colors is 2.
Now the worst case is when the pair is not completed until we draw all the yellow color.
That will happen at 12 + 1 = 13 draws (pair needs 2 blue, and the worst will happen that in initial trials, the yellow socks are not letting the pair get completed, which means at max 1 blue sock and rest 12 socks are drawn, which will get at max 13 draws).
But now any more sock pulled will have to be falling into the blue color category we already have. (this is exactly the pigeonhole principle's use).
After 13 times, you will start getting blue socks.
Since you need a pair of blue socks, you need to pull out socks 1 more time.
So total 14 pulls were required if the conditions were like resisting us at maximum.
In most of the cases, we might not need those 14 pulls, but 14 pulls is the minimum number that will assure you that the socks pulled have a blue pair of socks.
If the conditions are not worst, we would be lucky and that
Thus, the smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A is correct).

To the nearest cent, how much will she have in 3 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$125.97
Step-by-step explanation:
They have given you everything you need.
p = 100
r = 0.08
t = 3
B = final amount
B = 100(1 + 0.08)^3
B = 125.9712
since you're dealing with money you have to round to the nearest cent
B = $125.97

The rectangle below has an area of x^2-6x-7 sq meters and a width of x-7 meters.
What expression represents the length of the rectangle?
Length=______ meters
Answer:
Length = ( x - 1 ) ( m)
Step-by-step explanation:
Area of rectangle is:
A(r) = l*w ( in m² ) where l is the length in m and w is the width in m
If we have: A(r) = x² - 6*x - 7 (m²), as an area of a rectangle, then we can factoring the equation, and get the rectangle dimensions, then:
x² - 6*x - 7 = ( x - 1 ) * ( x - 7 ) = area of the rectangle in m²
As problem statement establishes that ( x - 7 ) ( m) is the width, then
( x - 1 ) ( m) is the length

As an estimation we are told £3 is €4.
Convert £10.70 to euros.
Give your answer rounded to 2 DP.
Answer:
From the estimation,
£10.7 = €14.27
Step-by-step explanation:
Given the conversion rate between the pounds and the euro currencies, we are to convert an amount in pounds to euros
From the estimate;
3 pounds = 4 euros
Thus;
10.7 pounds = x euros
We are using x since the value in euros is not known presently.
To move from here, we simply cross multiply.
That would give;
3 * x = 4 * 10.7
3x = 42.8
x = 42.8/3
x = 14.2666
x = €14.27

The average mark of candidate in an aptitude test was 128.5 with a standard deviation of 8.2. Three scores extracted from the test are 148, 102,152. What is the average of the extracted scores t hat are extreme values (outliers)?
Answer:
Step-by-step explanation:
Given that : The average marks of candidates in an aptitude test was 128.5 with a standard deviation of 8.2. Three scores extracted from the test are; 148, 102 and 152.
The objective here is to determine the average of the extracted scores that are the extreme values (outliers)
NOW:
The average marks of candidates in an aptitude test was 128.5
i.e the Mean = 128.5
Standard Deviation = 8.2
outlier will be outsides;
then the range will be Mean ± 3 × SD
= 128.5 ± 8.2 × 3
= 128.5 ± 24.6
Range is ( 103.9 , 153.1)
102 is outside this range
Hence, the average of the extracted scores that are extreme values (outliers) will be 102 only

Answer: 18 square feet.
Step-by-step explanation:
You can find the surface area of the ice cubes by taking the area of each square side and multiplying it by 6.
1 * 1 = 1, so each side is 1 square foot.
There are six sides on a cube, so each ice cube has a surface area of six feet squared.
There are three ice cubes there, so 3 * 6 = 18 square feet.
Three ice cubes have a surface area of 18 feet squared.

The circle passes through the point (3,6). What is it’s radius?
Answer:
c. 5
Step-by-step explanation:
In the attached image we can calculate the radius in a very simple way, if we focus on the axis of the "y" we have that there is a distance that would be the diameter of the circle and goes from -2 to 8.
Between -2 and 8, there is a quantity of 10 units, since:
8 + 2 = 10
they are added because we want to know the total distance, therefore the diameter is 10, and we know that the radius is half the diameter, so:
r = d / 2
r = 10/2
r = 5
therefore the radius is 5 units, that is, the answer is c. 5

The lines are perpendicular and the slope of the red line is m₂ = -2/3
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m₁ = 3/2
So , the slope of the green line is m₁ = 3/2
Since the lines are perpendicular to each other , the product of their slopes will be equal to -1
And , m₁ x m₂ = -1
So , ( 3/2 ) x m₂ = -1
Multiply by ( 2/3 ) on both sides , we get
m₂ = ( -2/3 )
Therefore , the slope of the red line is ( -2/3 )
Hence , the slope of the red line m₂ = ( -2/3 )

9) v - 15 = -27 10) n + 16 = 9
Answer:
9) v= -12
10) n= -7
Step-by-step explanation:
9) v - 15 = -27
Add 15 from both sides
i.e. v - 15 + 15 = -27 + 15
v = -12
10) n + 16 = 9
Subtract 16 from both sides
i.e. n + 16 - 16 = 9 - 16
n = -7

what is the slope of the line ?
Answer:
-3/4
Step-by-step explanation:
To find the slope of a line, you need to see how much it "rises" over a certain amount of "run". In other words, for a given amount of distance traveled along the x axis, how much it traveled vertically along the y axis. In this line, for every 4 units moved to the right, the line goes up by -3 units. Therefore, the slope of the line is -3/4. Hope this helps!

Are these two Equivalent
Answer:
no they're not
Step-by-step explanation:
4(x+2) = 4x +8
4x+2= 4x+2
Answer:
No they are not equivalent
First we would have to solve 4(x+2)
In order to solve this we need to multiply. So 4×X is equal to 4x. 4×2=8 Therefore when solving Its 4x+8..and 4x+8 is not equivalent to 4x+2

(2. 6x + 5 = 3x + 14) (6. 7x + 2 = 5x + 14) (10. 6x - 5 = 13 - 3x)
(3. 12x + 5 = 4x + 37) (7. 13x - 15 - 12x + 16) (11. 4x - 9 = 6 - x)
(4. 3x + 8 = 2x +21) (8. 9x - 19 = 2x - 5) (12. 5x - 2 = 10 - x)
Answer:
Step-by-step explanation:
1) 7x - 14 = 2x + 11 {Add 14 to both sides}
7x - 14 +14 = 2x + 11 +14
7x = 2x + 25
7x - 2x = 2x + 25 - 2x
5x = 25 {Divide both sides by 5}
5x/5 = 25/5
x = 5
2) 6x + 5 = 3x + 14
6x = 3x + 14 - 5
6x = 3x + 9
6x - 3x = 9
3x = 9
x = 9/3
x = 3
3) 12x + 5 = 4x +37
12x = 4x + 37 - 5
12x = 4x + 32
12x - 4x = 32
8x = 32
x = 32/8
x = 4
4) 3x + 8 = 2x + 21
3x = 2x + 21 - 8
3x = 2x + 13
3x - 2x = 13
x = 13
5) 5x + 3 = x + 11
5x = x + 11 -3
5x = x + 8
5x - x = 8
4x = 8
x= 8/4
x = 2
Answer: Step-by-step explanation:
1) 7x - 14 = 2x + 11 {Add 14 to both sides}
7x - 14 +14 = 2x + 11 +14
7x = 2x + 25
7x - 2x = 2x + 25 - 2x
5x = 25 {Divide both sides by 5}
5x/5 = 25/5
x = 5
2) 6x + 5 = 3x + 14
6x = 3x + 14 - 5
6x = 3x + 9
6x - 3x = 9
3x = 9
x = 9/3
x = 3
3) 12x + 5 = 4x +37
12x = 4x + 37 - 5
12x = 4x + 32
12x - 4x = 32
8x = 32
x = 32/8
x = 4
4) 3x + 8 = 2x + 21
3x = 2x + 21 - 8
3x = 2x + 13
3x - 2x = 13
x = 13
5) 5x + 3 = x + 11
5x = x + 11 -3
5x = x + 8
5x - x = 8
4x = 8
x= 8/4
x = 2
