Answer:
Step-by-step explanation:
The 3 angles must add up to 180. So
6x + 4x + 2x = 180
12x = 180
x = 15
Plug this into all the angles and you have your answers
Answer:
Step-by-step explanation:
The sum of a triangles angles is always 180 degrees.
2x+4x+6x=180
12x=180
x=15
A=6x=6(15)=90 degrees
B=2x=2(15)=30 degrees
C=4x=4(15)=60 degrees

What is a unique characteristic of a set of data that is distributed normally?
A. the mean is greater than the median
B. the mean is less than the median
C. the mean is the same as the median
D. the data set does not have a median
Answers
Answer:
C
Step-by-step explanation:
Normal distribution has a unique characteristic of having equal mean and median values. If mean was higher than median, then the distribution would be positively skewed. Mean lower than median would appear in distributions negatively skewed. Each data set has a median value.
After 10% tax, the phone cost $220. What was the original price?
Answers
Answer:
$198
Step-by-step explanation:
To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

(-7, y) and (-2,-4); m = -6/5 find the slope
Answers
Answer:
y = 2
Step-by-step explanation:
Use the slope formula so y2-y1/x2-x1 = -6/5
so -4 - y / -2 + 7 = -6/5 so y has to be 2 so that -4-2=-6

A compact disc player costs £50 plus 17 1/2 % VAT.
Calculate the total cost of the compact disc player.
Answers
Answer:
£58.75
Step-by-step explanation:
Given data
Cost = £50
VAT= 17 1/2%= 17.5%
Let us find the amount of the VAT
=17.5/100*50
=0.175*50
= £8.75
Hence the total cost of the compact disk is
=50+ 8.75
=£58.75

A dilation has center (0,0). Find the image of the point L(6-8) for the scale factor 7.
Answers
Answer:
D (42,-56)

Scale factor means you multiply, so you multiply (6,-8) by 7.
6 x 7 is 42 and 7 x -8 is -56. So your answer is D (42,-56).
14 = p + 19 I need some help with this one?
Answers
Answer:
p=-5
Step-by-step explanation:
have a lovely day!!
That is bc if +19 has a + u make it - so then u subtract.
So 19-14=15 to find the p.
P=15
If the 19 was -19 instead of +19 then u would do.
19+14= 43. Which would then be.
P=43.
Hope this helps!
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use? Laws of Sines or Laws of Cosines? and why?
Answers
Answer:
We would use the Law of Cosines to solve the question.
m∠ W = 121.8°
Step-by-step explanation:
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use?
The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.
Law of cosines when we are to find an unknown angle =
m∠ W = arc cos [u² + v² - w²/ 2uv]
m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]
m∠ W = 121.81159°
Approximately = 121.8°
A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes
Answers
Answer:
Option D, the volume is 15.625 cubes
Step-by-step explanation:
For a cube of side length L, the volume is:
V = L^3
for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:
v = (1in)^3 = 1 in^3
Then:
1 in^3 is equivalent to one small cube
Here we know that the side length of our cube is (2 + 1/2) in
Then the volume of this cube will be:
V = [ (2 + 1/2) in]^3
To simplify the calculation, we can write:
2 + 1/2 = 4/2 + 1/2 = 5/2
Then:
V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3
This means that 15.625 small cubes will fill the prism.
So the correct option is D.
