An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
x=36.1
supplementary angle = 143.9 degrees
Step-by-step explanation:
angle: x
supplementary angle: 180-x
x = (180-x)-107.8
2x = 72.2
x = 36.1 degrees
180-x = 143.9 degrees
supplementary angle = 143.9 degrees
x measures 107.8 less than 180-x
x=180-x-107.8
x=72.2-x
Add x to both sides
2x=72.2
Divide both sides by 2
x=36.1

If a line contains the point (0,-1) and has a slope of 2 what point is on the line A.(2,1) B.(1,1) C.(0,1)
Answer: B. (1,1)
Step-by-step explanation: If you find slope with the points (0,-1) and (1,1) you will get a slope of 2.
the formula you can use is y2-y1/x2-x1
substitute the values with the 2 points i mentioned
1-(-1)=2
1-0=1
divide 2/1
and you get 2
So B, (1,1) would be your answer.
Graph a line that contains the point (6,-5)
Answer:
y=-5
Step-by-step explanation:
It must contain (6, -5). Therefore, I went the easy way and created a line that has y = -5 no matter what x is. You can put 0x-5 if you want to make sure the independent variable is x.
How many protons would make up 9.435 x 10-22 g?
Answer:
Mass of proton (m) = 1.67×10^(-27) kg
Step-by-step explanation:
Mass of proton (m) = 1.67×10^(-27) kg.
Since, 1 kg = 1000 g
Therefore, m = 1.67x10^(-27+3) g = 1.67x10^(-24) g
Let N no. of protons be present in 1 g. Hence, Nxm = 1 g
So, N = 1 / m = 1 / (1.67x10^(-24))
N = 6x10^(23) (approx.)
Exact mass of proton gives N = 6.022 x 10^(23).
That is a very special no. In fact, it is the Avogadro’s constant used frequently in chemistry. Avogadro’s no. is actually the number of atoms in exactly 12 g of C-12 isotope of carbon. Since, the atomic mass of C-12 is 12 u (unified mass), then again the no. of carbon atoms turn out to be N.

Will switching points when calculating distance affect the final answer? Explain. (1 point)
Switching points when calculating distance will affect the final answer because the formula adds the differences of the corresponding X-
and y-values
Switching points when calculating distance will not affect the final answer because the formula adds the differences of the
corresponding X- and y-values.
Switching points when calculating distance will affect the final answer because the formula finds the differences of the corresponding x-
and y-values
Switching points when calculating distance will not affect the final answer because the formula squares the differences of the
corresponding X- and y-values.

Factoring Completely:
x^2-16x+48
Answer:
(x - 12)(x - 4)
Step-by-step explanation:
Given
x² - 16x + 48
Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 16)
The factors are - 12 and - 4, since
- 12 × - 4 = + 48 and - 12 - 4 = - 16 , thus
x² - 16x + 48 = (x - 12)(x - 4) ← in factored form

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 28 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that time, which elevator is deeper?
Answer:
equipment: -252 feet; miners: -224 feetequipment is deeperStep-by-step explanation:
The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.
After 14 more seconds, the positions are ...
equipment: -6(42) = -252 feet relative to the surface
miners: -16(14) = -224 feet relative to the surface
The equipment elevator is deeper.
Calculate the median, the range and identify the Q1 and Q3 for the following set: 5, 1, 6, 8, 1, 7, 4, 5, 6, 11, 3, 4, 4, 2, 5, 5 (hint draw a box and whisker plot)
Answer:
Arrange the data in ascending order
1,1,2,3,4,4,4,5,5,5,5,6,6,7,8,11
n=16
position of median = (n+1)/2 = 17/2 = 8.5 th item
8.5 th item is the average of 8 and 9th item
median = (5+5)/2 = 5
Range = largest value - smallest value
= 11 -1 = 10
position of Q1= (n+1)/4 = 17/4 = 4.25 th item
Q1 = 4 + 0.25(5th item - 4th item )
4 + 0.25(4-3)
= 4.25
position of Q3= (n+1)/4 = 3*17/4 = 12.75 th item
Q1 = 12 + 0.75(13th item - 12th item )
12 + 0.75(6-6)
= 12

A triangle with the coordinates X(3, 2), Y(5, -1), and Z(-2, 3) is reflected across both the x- and y-axes. The coordinates after both reflections are what
Answer:
The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].
Step-by-step explanation:
Let be a point [tex](a,b)\in\mathbb{R}^{2}[/tex], reflections across x- and y-axes are represented by the following operations:
x-Axis reflection:
[tex]d = d'[/tex]
[tex]b - 0 = 0 - b'[/tex]
[tex]b' = -b[/tex]
y-Axis reflection:
[tex]d = d'[/tex]
[tex]a - 0 = 0 - a'[/tex]
[tex]a' = -a[/tex]
If we know that [tex]X (x,y) = (3,2)[/tex], [tex]Y(x,y) = (5,-1)[/tex] and [tex]Z (x,y) = (-2, 3)[/tex], the coordinates after both reflections are, respectively:
[tex]X'(x,y) = (-3,-2)[/tex]
[tex]Y' (x,y) = (-5,1)[/tex]
[tex]Z'(x,y) = (2,-3)[/tex]
The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].
The size of the largest angle in a triangle is 3 times the size of the smallest angle.
The other angle is 35 more than the smallest angle.
Work out in degrees the size of each angle in the trianlge
You must show your working
Answer:
a = 29
b = 64
c = 87
Step-by-step explanation:
Let the angles be a (smallest), b, and c (largest).
We know that a triangle's angles must add up to 180 degrees, so we can construct the following equations.
a + b + c = 180
c = 3a
b = a +35
With some solving and substitution...
a + (a + 35) + c = 180
2a + c = 145
2a + (3a) = 145
5a = 145
a = 29
and therefore,
b = 29 + 35 = 64
c = 3(29) = 87
Answer:
Let smallest angle be :x
So, the largest angle will be:3x
And the other angle will be :x+35
According to angle sum property of triangle,
x+3x+x+35=180
5x+35=180
5x=180-35
5x=145
x=(145/5)
Therefore, x=29
So, the smallest angle =x=29
The largest angle=3x=87
And the other angle=x+35=64

Explain what the intercepts mean in terms of the context and how to find them.
Answer:
Intercepts in terms of graphing are considered to be points at which a function crosses an axis. In the standard x and y graph (the Cartesian coordinate grid), one would find the intercepts by simply plugging in the value of 0 for either the x or the y to find either the y or x intercept respectively. For example, to find the y-intercept, you want to find (0,y) and to find the x-intercept, you want to find (x,0).

Wouldnt the answer be anything above 12? Because if Y is unknown, and you're taking 2 away from it, and it still has to be greater than 10, then it should be anything above 12. Unless it's saying that the number is greater than 10, and you are just taking away 2 from a number and it doesn't have to be greater than 10.
