Step-by-step explanation: 8: the image is a bit out of focus, so it's hard to tell what all the exponents are. Just remember that for negative exponents, the larger the number, the smaller the value.
9. Following the examples given, the exponent tells how many places to count from right to left to move the decimal from standard form to wavelength and vice-versa.
9b. Just put the numbers from standard form in order and find the corresponding color.
10. For multiplication, multiply the numbers to the left of the × and add the exponents of the 10. For division, Divide the numbers on the left and subtract the exponents of 10.
11a add the powers. Just like the first part of #10
11b same procedure as #10 (The more you practice, the more likely you will remember)

A study about commuting time for workers in a certain city. The distribution is clustered on the left with most of the values less than about 40 minutes commute. There are a fairly large number of values that are much higher, even stretching out to 150 minutes. There is a 15% chance that a random worker has a commute time of greater than 45 minutes. If you were to sketch this distribution, what would it look like, how would you describe it, and how do you represent the 15% probability?
Answers
Answer:
Following are the solution to this question:
Step-by-step explanation:
Its laborer's journey through time was concentrated mostly on left as well as the amounts are mostly less than 4 min. There are quite a lot of significantly higher levels, even stretching to 150 min. A hypothetical worker is 15% likely to get a time difference longer than 45 min.
They learn from such data that perhaps the distribution of data takes a very long time. Thus the distribution will look like an's progressive. Its probability is positive. Therefore some severe finding beyond the regular standards is included. The mean of findings is also higher than the mean. Its problem would be that 15% of people are more likely to have been traveling more than 45 min in a specific worker. Subsequently, the 85th level of the data is 45 minutes, meaning whether 85% of observations are decreased or equivalent to 45 minutes or 15% more than 45 minutes.Please answer ASAP

Line 2: x+1/6y=−5
Line 3: y=−6x−7
Line 4: y+3=1/8(x−1)
Lines 2 and 3 are perpendicular.
Lines 1 and 2 are perpendicular.
All four lines are perpendicular.
Lines 1 and 4 are perpendicular.
Answers
Answer:
All four lines are perpendicular
Step-by-step explanation:
Lines 1 and 2 are parallel
y+8x=−5;x+1/6y=−5
Lines 2 and 3 are parallel
x+1/6y=−5;y=−6x−7
Lines 1 and 4 are perpendicular they intercept
x+1/6y=−5;y+3=1/8(x−1)
All four lines are perpendicular
line 4 is perpendicular to all other lines
If Z is the centroid of triangle TUV, TZ=60, XZ=28, and WZ=25, find each missing measure
Answers
The measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.
If Z is the centroid of triangle TUV, then the following are true:
ZV = 2ZX
Given that ZX = 28,
ZV = 2(28)
ZV = 56
Similarly, TZ = 2ZY
60 = 2ZY
ZY = 60/2
ZY = 30
Also, ZU = 2WZ
ZU = 2(25)
ZU = 50
TY = 2ZY
TY = 2(30)
TY = 60
XV = XZ + ZY
XV = 28 + 50
XV = 78
Therefore the measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.

Find the angle of XYZ give your answer to 1 decimal place
Answers
Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:
[tex]\frac{sin(Z)}{XY}=\frac{sin(X)}{YZ}\\\\Substituting:\\\\\frac{sin(Z)}{6} =\frac{sin(90)}{15} \\\\sin(Z)=\frac{sin(90)*6}{15}\\\\sin(Z)=0.4\\\\Z=sin^{-1}(0.4)\\\\Z=23.6^o[/tex]
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°
What is the slope of a line which makes an angle of 45 degree with x-axis? *
Answers
Answer:
First we have to find slope m=Tan45°=1
so slope is 1.
Answer:
slope = 1
Step-by-step explanation:
The relationship between slope and the positive angle it makes with the x- axis is
slope = tanθ ( θ is the angle measured from the x- axis ), then
slope = tan45° = 1
One gallon of paint covers about 450 square feet. How many square feet 1.5 gallons of paint covers?
Answers
675 square feet
Step-by-step explanation:
It is given that 1 gallon of paint covers about 450 square feet.
To calculate how many square feet will 1.5 gallon of paint cover, we have to multiply 450 by 1.5.
1.5 gallons of paint cover = 450 × 1.5 = 675 square feet.
1.5 gallon of paint will cover 675 square feet

Answers
Step-by-step explanation:
The given equations are :
y = x + 3 .....(1)
y = 2x – 5 ......(2)
The table for equation (1) is :
x = 0, 1, 2, 8
y = 3, 4, 5, 11
The table for equation (2) is :
x = 0, 1 , 2, 8
y = -5, -3, -1, 11
From the graph we can see that,
The x-value is = 8
The y-value = 11
The solution is = (8,11).
The x-value is = 8, the y-value = 11 and the solution is = (8,11)
How to determine the equation solutions?The equations are given as:
y = x + 3
y = 2x - 5
Next, we plot the graph of the equations
From the graph of the equations, we have:
(x,y) = (8, 11)
Hence, the x-value is = 8 and the y-value = 11
So, the solution is = (8,11)

Answer:
solving [tex]100x^2-4=0[/tex] we get [tex]x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]
Step-by-step explanation:
We need to solve [tex]100x^2-4=0[/tex]
We know that [tex]10^2=100 \: and\: 2^2=4[/tex]
Replacing with the squares
[tex]100x^2-4=0\\(10x)^2-(2)^2=0[/tex]
We can use the formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
Applying formula
[tex](10x+2)(10x-2)=0\\10x+2=0\:,\:10x-2=0\\10x=-2\:,\:10x=2\\x=-2/10\:,\:x=2/10\\x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]
So, solving [tex]100x^2-4=0[/tex] we get [tex]x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]
