Answer:
215/3
Step-by-step explanation:
71 multiplied by 3 (denominator) + 2 (remainder) divided by 3
The improper fraction for the given mixed fraction is 215/2.
The given fraction is [tex]71\frac{2}{3}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as: [tex]a\frac{b}{c} = \frac{(a\times c)+b}{c}[/tex]
Now, [tex]71\frac{2}{3}=\frac{71\times3+2}{3}[/tex]
= (213+2)/3
= 215/3
Therefore, the improper fraction for the given mixed fraction is 215/2.

What is the equation of the line that is perpendicular to the line y=-2x+10 and passes through the point (-8,12)?
Answer:
y=1/2x+16
Step-by-step explanation:
m= -2, mperpendicular = -1/2
y-12=1/2 * (x+8)
y=mx+b form
y = 1/2x+16
At the MOA, 2 shakes and 3 hamburgers cost $17.00. If you order 3 shakes and 4 hamburgers the cost will be $24.00. What is the cost of each item? Answer quick plz
Answer:
Step-by-step explanation:
Let shakes be s and hamburgers be h. Then the total cost equation would be
2s + 3h = 17
The next equation in our system will be
3s + 4h = 24
You can solve this by either substitution or elimination. I'm going with substitution because it's easier in this platform to do so. I'm going to solve the second equation for h.
4h = 24 - 3s and
h = 6 - .75s
Now we will sub that into the first equation to get
2s + 3(6 - .75s) = 17 and
2s + 18 - 2.25s = 17 and
-.25s = -1 and
s = 4
That means that shakes cost $4 each. Now plug in 4 for s and solve for h:
h = 6 - .75(4) and
h = 6 - 3 so
h = 3 so hamburgers cost $3 each.

The following diagram models a ratio relationship.
A. Write a part-to-part ratio to represent this ratio relationship.
B. Use ratio language to describe this ratio relationship.
The part-to-part ratio to represent this ratio relationship is 1:0.75.
The ratio language to describe this ratio relationship shows that for every four squares, there are three triangles.
How to illustrate the information?Based on the information given, it should be noted that the part-to-part ratio to represent this ratio relationship is 1:0.75.
This illustrates that for every one square, there is 0.75 triangle.
This was based on the fact that there are 3 triangles and 4 squares. This will be:
= 3/4 = 0.75
Therefore, the ratio language to describe this ratio relationship shows that for every four squares, there are three triangles.

Of a box of paper clips, 2/3 are red and the rest are green. If there are 120 red paper clips, how many green paper clips are there.
Answer:
There are 60 green paper clips.
Step-by-step explanation:
if 2/3 of the box = 120 clips, then you can determine that 1/3 is 60, since 1/3 is half of 2/3. If 1/3 is 60, Since you already know that 2/3 is 120 clips, you add 60 to get 180 total clips, and 60 of them are green.
Answer:
60 Green Paper Clips
Step-by-step explanation:
120/2 = 60 (which would be 1/3)

Answer:
$308
Step-by-step explanation:
Solve for the indicated variable.
q = c4(h + r) for r
Select one:
a. r = 4cq - h
b. r = q4c - h
c. r = 4q−hc
d. r = 4qc - h
Answer:
Option (c) "[tex]r=\dfrac{q}{4c}-h[/tex]"
Step-by-step explanation:
The given equation is :
q = c4(h + r)
We need to solve it for r.
Dividing both sides of the given equation by 4c.
[tex]\dfrac{q}{4c}=\dfrac{4c}{4c}(h+r)\\\\(h+r)=\dfrac{q}{4c}[/tex]
Now, subtract h both sides of the equation.
[tex]h+r-h=\dfrac{q}{4c}-h\\\\r=\dfrac{q}{4c}-h[/tex]
Hence, this is the required solution.
How many significant digits are there in the measurement 84,000 kg
Answer:
[tex]\boxed {\boxed {\sf 2 \ significant \ figures}}[/tex]
Step-by-step explanation:
According to the "rules" of significant figures, all the zeroes to the right of the final non-zero number are not significant, unless there is a decimal point.
We are given the measurement:
84,000 kg
If there was a decimal point (84,000.0 kg), then there would be 5 significant figures.
Since there isn't a decimal point, all 3 zeroes to the right of the number 4 aren't significant. The 8 and 4 are significant, so there are 2 significant figures.
The annual profit P(t) of the Enviro Company, in thousands of dollars, is
given by
P(t) = 2+3 – 152++ 3400t + 30
where t is the number of years since 1960, the first year that the company
showed a profit.
Fill in the blanks below. All answers should be rounded to the nearest dollar.
Do not use commas in your solution.
The profit in 1960 was____ dollars.
Answer:
The profit in 1960 (i.e. year 1) was 3280 dollars
Step-by-step explanation:
Given
[tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex]
Where
t = years since 1960 (the first year)
Required
Determine the profit in 1960
Since the first year is 1960, then [tex]t =1[/tex]
To get the profit, we simply substitute 1 for t in [tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex]
[tex]P(t) = 2t^3 - 152t^2 + 3400t + 30[/tex] becomes
[tex]P(1) = 2(1)^3 - 152(1)^2 + 3400(1) + 30[/tex]
[tex]P(1) = 2*1 - 152*1 + 3400*1 + 30[/tex]
[tex]P(1) = 2- 152 + 3400 + 30[/tex]
[tex]P(1) = 3280[/tex]
Hence, the profit in 1960 (i.e. year 1) was 3280 dollars

"The cost of sending mail is $0.37 for a letter weighing less than 1 ounce, $0.60 for a letter weighing at least one ounce, but less than 2 ounces, and $0.83 for a letter weighing at least 2 ounces, but less than 3 ounces."
Write a function c(x) that gives the cost of mailing a letter weighing x ounces.
Answer:
Step-by-step explanation:
this is a piecewise function
in this context, to find the cost of any package weight x you figure out which piece of the function it fits in.
examples:
x = .5
c(x) = 0.37 (because x is less than 1)
x = 1
c(x) = 0.60 (because x is equal to 1 but still less than 2)
x = 2.9
c(x) = 0.83 (because x is more than 2 but less than 3)

There are 35 beverages on the table if the ratio of beverages is 3:2 coffee to tea how many cups of coffee are there in total
Answer:
21 cups of coffee
Step-by-step explanation:
So the coffee:tea is 3:2. We can put it as 3x+2x=35 as we know there are 35 drinks, do not know the exact number of coffee and tea, but know the ratio.
3x+2x=353x+2x=35 Combine like terms, 5x=35Divide by 5 to isolate variable, x=7Now, x=7. So coffee is 3(7)=21 and tea is 2(7)=14.

Step-by-step explanation:
In a recent year, the mean number of strokes per hole for a famous golfer was approximately 3.9.(a) Find the variance and standard deviation using the fact that the variance of a Poisson distribution is σ2=μ.(b) How likely is this golfer to play an 18-hole round and have more than 72 strokes?
Answer:
Variance = 3.9
Standard deviation = 1.975
p(x > 72) = 0.38482
Step-by-step explanation:
Given that :
Mean number (μ) of strokes per hole is approximately 3.9
For a poisson distribution :
σ² = μ
Hence,
Variance (σ²) = μ = 3.9
The standard deviation σ = √(σ²)
σ = √3.9 = 1.9748417
Poisson distribution relation :
p( x = x) = (λ^x * e^-λ) / x!
For an 18-hole round :
λ = 18 * 3.9 = 70.2
Using the poisson distribution calculator ; where λ = 70.2 ; x = 72
p(x > 72) = 0.38482
Evaluate ( f g )(x) if f(x) = 3x2 + 3 and g(x) = 3x – 1 when x = 2.
Answer:
[tex](fg)(x) = 75[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^2 + 3[/tex]
[tex]g(x) = 3x - 1[/tex]
Required
Evaluate (fg)(x) for x = 2
In algebra functions
[tex](fg)(x) = f(x) * g(x)[/tex]
Substitute values for f(x) and g(x)
[tex](fg)(x) = (3x^2 + 3) * (3x - 1)[/tex]
Substitute 2 for x
[tex](fg)(x) = (3*2^2 + 3) * (3*2 - 1)[/tex]
[tex](fg)(x) = (3*4 + 3) * (6 - 1)[/tex]
[tex](fg)(x) = (12 + 3) * (5)[/tex]
[tex](fg)(x) = (15) * (5)[/tex]
[tex](fg)(x) = 15 * 5[/tex]
[tex](fg)(x) = 75[/tex]

Answer:
4/3, or 1 1/3
Step-by-step explanation:
For a whole number, 1 is always the denominator. It would look like 4/1 x 3/8. Then you would multiply both the numerators and denominators. That would get you 12/8. Simplify it, to get 4/3. If you want to simplify it even more, you would get 1 1/3.

4x+7=23. explain the steps you would use to solve the equation for x.
Answer:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4
Answer:
x=4
Step-by-step explanation:
4x+7=23
Collect like terms
4x=23-7
4x=16
Divide both sides by the co-efficient of x
4x/4=16/4
x=4
