Answer: .13
Step-by-step explanation:
63/100=0.63
5/10=0.50
=.13
I took 63 and divided it by 100 to get .63 and took 5 and divided it by 10 to get .50 so I took them and subtracted them to get .13
Im solving variables 31 = 3 (y+7) - 8y
Answer:
y = -2
Step-by-step explanation:
31 = 3 (y+7) - 8y
31 = 3y +21 - 8y
31 = -5y +21
10 = -5y
-2 = y
what is -23 = -11n + 10 + -3 + 9b = -48 i nEeEd HalPPP

1) Give an example of a rational number AND an irrational number.
What is the difference between them?
2) What is the decimal equivalent of your two examples?
3) Can every repeating decimal be written as a rational number? Explain why or why
not.
Answer:
Step-by-step explanation:
A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.
A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5
Pi is irrational. I don't know the value of pi beyond what a calculator can tell me. 3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.
Repeating decimals call always be represented as a fraction. For ex
x = 0.123123123123123
1000x = 123.123123123123
x = .123123123123123 Subtract
999x = 123
This comes about because in both cases what is after the decimal is the same.
x = 123/999 = 41/333

Answer:
y=-3x+2
y = [tex]\frac{1}{5}[/tex]x - 5
Step-by-step explanation:
Question 1
It is given that;
- one of the lines has an equation of; y = -3x-7
- the given line's y-int is (0, 2) ~(The y-int is when the line crosses the y axis, hence x is zero)
- these two lines are parallel
When two lines are parallel, their slope is the same, hence the equations of the given line would look like this;
y = -3x + 2
In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).
Questions 2
It is given that;
- one of the lines has an equation of y = -5x + 1
- the given line's y-int is (0, -5) ~(The y-int is when the line crosses the y axis, hence x is zero)
- these two lines are perpendicular
When two lines are perpendicular, their slopes are the negatives reciprocal of each other, hence the equations of the given line would look like this;
y = [tex]\frac{1}{5}[/tex]x - 5
In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

A patch of farmland is currently worth $78,125. The expected increase in its market value can be modeled by the function below, where tis the
time in years.
P(t) = 78,125 0.025:
How many years will it take for the farmland's market value to reach $125,000?

years
Reset
Next
Answer: t = 18.8 years
Step-by-step explanation: The modeled function is an exponential function:
[tex]P(t)=78,125e^{0.025t}[/tex]
which is farmland worth along time.
To determine when the farmland will be worth $125,000:
[tex]125,000=78,125e^{0.025t}[/tex]
[tex]e^{0.025t}=\frac{125,000}{78,125}[/tex]
[tex]e^{0.025t}=1.6[/tex]
Apply natural logarithm:
[tex]ln(e^{0.025t})=ln(1.6)[/tex]
And then, power rule:
[tex]0.025t=ln(1.6)[/tex]
[tex]t=\frac{ln(1.6)}{0.025}[/tex]
t ≈ [tex]\frac{0.47}{0.025}[/tex]
t ≈ 18.8
After 18.8 years, the farmland will reach market value of $125,000.

Answer:
1. m<rsv is 42 degrees
2.
Step-by-step explanation:
1.
2. Since abc is 95, the two angles you have to solve are going to equal 95 when added because they make up the angle ABC so solving it would be like
(2x+23)+(9x-5)=95 you then solve this which would be
2x+23+9x-5 = 95 - Combine like terms
11x+18=95 Subtract 18 both sides
11x=77 divide by 11
x=7
After this you just put 7 in the equations instead of X and solve it
making angles

The last one is y-2=-(x-4) sorry I couldn’t fit it all in
Answer:
y + 2 = (x - 2)
Step-by-step explanation:
From the graph, you can see that when y = 0, x = 2, and vise versa. Taking this into consideration, if y = 4, x = 2, so, the answer is y + 2 = (x - 2)

If there's a three day rain forecast for the probability of rain , 70% Friday, 70% Saturday, 70% Sunday A) work out the probability that it will rain on all three days B) work out the probability that it will rain on exactly two consecutive days
Answer:
a) 34.3%
b) 49%
Step-by-step explanation:
In order to find the probability of a sequence of events, we need to multiply each individual probability by the others in decimal form. Therefore, we need to turn these probabilities into decimal form by dividing them by 100 like so..
70% / 100 = 0.70
Now we multiply all of them together and multiply the product by 100 to get the percentage.
0.70 * 0.70 * 0.70 = 0.343
0.343 * 100 = 34.3%
34.3% is the probability of it raining on all three days. Now to find the probability of it raining on two consecutive days we do the same but multiply only 2 probabilities
0.70 * 0.70 = 0.49
0.49 * 100 = 49%
One newspaper reported that the mayor received a salary increase of 5%.Another paper reported that the mayor’s salary went up $2000. What was the mayor’s salary before the increase?
Answer:
$1900
Step-by-step explanation:
5% increase is $100 dollar
Answer:
Let
x= Mayor’s previous salary
y=his increased salary
5% increase means
(105/100)*x=y——-(1)
From the other reporter
The Mayor’s salary went up $2000
:. y-x=2000———-(2)
Put y= (105/100)*x into equation 2
105x/100 -x =2000
Multiply through by 100
105x-100x=200000
5x=200000
Divide both sides by 5
x=40000
Hence his previous salary was $40,000 and current one is
y=2000 +40000
y=$42000
Step-by-step explanation: from your question, you didn’t state whether it went up by 2000 or went to 2000. I chose went by 2000. If it were to be went to 2000 , the equation will be different. It would been 2000-x=y

A plot of land is in the shape of a triangle. Two of the angles measure 48 degrees and 74 degrees. The length of the side between them is 90 m.
a) calculate the perimeter of the plot, to the nearest meter.
b) calculate the area of the plot, to the nearest square meter.
Answer:
Perimeter = 271 meters
Step-by-step explanation:
third angle measure would have to be 180 - 122 = 58 degrees
you can use the law of sines:
sin 58° = sin 74°
90 b
.85 = .96
90 b
cross-multiply: .85b = 86.4
b = 102
now do again to find third side:
sin 58° = sin 48°
90 c
.85 = .74
90 c
.85c = 67
c = 79
now you know all 3 sides so add them to get perimeter (79+102+90) = 271
