The m∠P is three less than twice the measure of ∠Q. If ∠P and ∠Q are supplementary angles, find the measures of both angles.
Answers
Answer:
m∠P =119
m∠Q = 61
Step-by-step explanation:
m∠P = 2(∠Q)-3 or p=2(q)-3
supplementary angles so they combine to equal 180!
soooooo we can take
q+p=180
input what p equals and you get
q+ 2(q)-3=180
3q-3=180
3q=183
q=61
now we have what m∠Q is, so just subtract that from 180 to get m∠P
180-61=119
for a certain online store, the distribution of number per hour is approximately normal with mean 1200 purchases and standard deviation 200 purchases. for what proportion of hours will the number of purchases at the online store exceed 1400?
a)5%
b)68%
c)16%
d)32%
Answers
Answer: 16%
Step-by-step explanation:
When we have a normal distribution, the 100% of our sample will be placed in a "gaussian bell".
Where the middle of this bell coincides with the mean.
The mean, in this case, is 1200, and the standard deviation is 200.
In the image below you can see that between the points.
Mean + standard deviation and the end of the graph, we have:
13.5% + 2.35% + 0.15% = 16%
And particularly, if we want to know the percentage that exceed 1400, will be the same percentage above the mean plus the standard deviation.
mean = 1200
SD = 200
mean + standard deviation = 1200 + 200 = 1400.
Then the percentage that exceeds 1400 is equal to the percentage that we found above, then the correct option is C: 16%

[tex]x=7[/tex]
Step-by-step explanation:
[tex]\sqrt{3x+8}=\sqrt{4x+1}[/tex]
Square both sides:
[tex](\sqrt{3x+8})^{2} =(\sqrt{4x+1})^{2}[/tex]
[tex]3x+8=4x+1[/tex]
Subtract 8 from both sides:
[tex]3x+8-8=4x+1-8[/tex]
[tex]3x=4x-7[/tex]
Subtract 4x from both sides:
[tex]3x-4x=4x-7-4x[/tex]

Divide both sides by -1:

In the following figure, three layers of cubes are stacked on top of each other. How many cubes of any size are in the figure?
Answers
Answer:
14
Step-by-step explanation:
It's 3x3, 2x2, and 1x1
9+4+1=14
Answer:
14 cubes
Step-by-step explanation:
The figure, there are 3 layers, so we can split up the layers.
In the 1st layer is just 1 cube.
In the 2nd layer:
2 x 2 = 4 cubes.
In the 3rd and final layer:
3 x 3 = 9 cubes.
We then add them:
1 + 4 + 9, giving us a total of 14 cubes.

The width of a rectangle is 5 feet less than the length. The perimeter is 62. Find the length and width of the rectangle.
Variables: ___________________________
Model equation: ______________________________
Length of the rectangle: ______________________________
Width of the rectangle: ______________________________
Answers
Perimeter formula: p = 2(w + l)
The perimeter is 62.
p = 62
The width of a rectangle is 5 feet less than the length.
w = l - 5
Substitute and solve.
62 = 2[(l - 5) + l)]
62 = 2l + 2l - 10
62 = 4l - 10
72 = 4l
18 = l
Substitute and solve for the width
w = 18 - 5
w = 13
Therefore, the length is 18 and the width is 13.
Best of Luck!
Answer:
see below and attached.
Step-by-step explanation:
Perimeter (P) = 2 L (Length) + 2 W (Width)
where P = 62
W = L - 5
P = 2L + 2W
62 = 2L + 2(L -5)
62 = 2L + 2L - 10
72 = 4L
L = 72/4
L = 18
W = L - 5
W = 18 - 5
W = 15
Variables : P, L, W
Model equation: P = 2L + 2W
Length of the rectangle: 18
Width of the rectangle: 13
