Answer:
10/27
Step-by-step explanation:
First of all, to simplify a fraction, you have to find a common factor for each of the numbers. First, we know that 30 and 81 can be divided by 3, which will result in the number 10 and 27. Since 10/27 don't have any common factors, you cannot simplify it further.
y=-5x+6. y=3x-2 what do the values of x and y represent
Answer:
x=1; y=1
Step-by-step explanation:
Step-by-step explanation:
Given:
y=-5x+6 ----------(1)
y=3x-2 ----------(2)
As L.H.S from equation 1 and 2 are equal R.H.S will also be equal
Therefore
-5x+6=3x-2
-5x-3x=-2-6
-8x=-8
x=1
put x=1 in equation (1)
y=-5×1+6
y=-5+6
y=1
Therefore , x=1 and y=1.

Which of the following is not an example of a perfect square? a √9 b √200 c √4 d √64
Answer:
b= 200 is not an example of a perfect square
Wetlands offer a diversity of benefits. They provide a habitat for wildlife, spawning grounds for U.S. commercial fish, and renewable timber resources. In the last 200 years, the United States has lost more than half its wetlands. Environmental Almanac gives the percentage of wetlands lost in each state in the last 200 years. For the lower 48 states, the percentage loss of wetlands per state is as follows:
46 37 36 42 81 20 73 59 35 50
87 52 24 27 38 56 39 74 56 31
27 91 46 9 54 52 30 33 28 35
35 23 90 72 85 42 59 50 49
48 38 60 46 87 50 89 49 67
The percentages are concentrated from 20% to 60% The percentages are concentrated from 60% to 90%
There is a gap showing that none of the lower 48 states has lost from 60% to 69% of its wetlands.
These data are strongly skewed left.
These data are fairly symmetric, perhaps slightly skewed right.
There is a gap showing that none of the lower 48 states has lost from 10% to 19% of its wetlands.
There are no gaps in the data.

An ad for an above-ground pool states that it is 25 m2. From the ad, you can tell that the pool is a circle. If you swim from one point at the edge of the pool to another, along a straight line, what is the longest distance d you can swim? Express your answer in three significant figures.
Answer:
d ≈ 5.64 m
Step-by-step explanation:
We are told that the pool is circular and that the area is 25 m².
Now, the longest chord that connects two points in a circle is the diameter.
Thus, the longest distance d will be the diameter
Area of circle is given by the formula;
A = πr²
Thus;
25 = πr²
r² = 25/π
r = √(25/π)
r = 5/√π
Diameter is twice the radius. Thus;
d = 2 × 5/√π
d = 10/√π
d ≈ 5.64 m

Find the value of x. Round to
the nearest tenth.
Answer:
13.7
Step-by-step explanation:
x is the side of the triangle opposite the given angle. 47 is the hypotenuse of that triangle. The trig function that relates the opposite side and the hypotenuse is ...
Sin = Opposite/Hypotenuse
sin(17°) = x/47
x = 47·sin(17°) ≈ 13.7
The value of x is 13.7.
What is the difference between a tax credit and a tax deduction?
a. A tax credit represents money owed to you, while a tax deduction represents money you owe.
b. A tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.
c. A tax credit is owed money that collects interest, while a tax deduction is money that you do not have to pay.
d. A tax credit occurs if you underpaid during the year, and a tax deduction occurs if you overpaid.
It is B
The difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.
What is Tax?
A financial charge that is imposed on a taxpayer in order to fund government spending and public expenditures is called tax. It is imposed by a governmental organization. It is a compulsory charge.
Given is tax credit and a tax deduction.
Tax credits and a tax deductions are same in a way that they will decrease what you pay in taxes. However, the method in which each of them work is quite different. Tax deductions lower your taxable income and will reduce what you'll pay in taxes, while tax credits reduce your tax bill dollar for dollar and may even increase your refund.
Therefore, the difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.

Use known logical equivalences to prove that a → (b → c) is logically equivalent to (a ^ b) → c.
Answer:-
a ∨ ( b ∨ c ) ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c
Step-by-step explanation:
Explanation :-
we know that b→ c ⇔ b∨c
Replacing b→ c ⇔ b ∨ c , we get
a → b ∨ c ,
By the same rule b→ c ⇔ b∨c
⇒ a ∨ ( b ∨ c )
Now
a ∨ ( b ∨ c ) ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

Answer: 15/32
Step-by-step explanation:
The data that we have is:
5/8 of the vegetable sold where green.
of theses 5/8, 3/4 were string beans.
Then the 3/4 is applied to the 5/8 of green vegetables.
Then the fraction (of the total number of vegetables) that were string beans was:
F = (3/4)*(5/8) = (3*5)/(4*8) = 15/32

Solve for x. Show steps.
1. 3x = 2x + 2
2. 3x + 5 = 4x + 1
3. 6x + 3 = 3x + 12
Step-by-step explanation:
3x = 2x + 23x - 2x = 2
x = 2
2. 3x + 5 = 4x + 1
4x - 3x = 5 - 1
x = 4
3. 6x + 3 = 3x + 12
6x - 3x = 12 - 3
3x = 9
x = 3
For the function f(x)=|4x−2|+10, evaluate f(−3).
Answer:
[tex]f(-3)=24[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=|4x-2|+10[/tex]
To find f(-3), substitute -3 for x:
[tex]f(-3)=|4(-3)-2|+10[/tex]
Multiply within the absolute value:
[tex]f(-3)=|-12-2|+10[/tex]
Subtract:
[tex]f(-3)=|-14|+10[/tex]
The absolute value of -14 is 14. Thus:
[tex]f(-3)=14+10[/tex]
Add:
[tex]f(-3)=24[/tex]

Margaret drove to a business appointment at 90 mph. Her average speed on the return trip was 80 mph. The return trip took 1/4
hr longer because of heavy traffic. How far did she travel to the appointment?
Distance = speed x time
Let the time to the appointment = x
The time home would be x + 1/4 hour
set up an equation you have 90x = 80(x + 1/4)
Simplify:
90x = 80x + 20
Subtract 80x from both sides:
10x = 20
Divide both sides by 10:
x = 2 hours
Distance = 90 x 2 = 180 miles

As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million. In mid-2016, what percent of the world's population was the Country A population? Round your answer as a percentage to one decimal place.
Answer:
The percentage of country A population to the world population
= 3.05%
Step-by-step explanation:
Country A population as of 2016
= 226 million
= 226000000
The world population as of 2016
= 7.4 billion
= 7400000000
The percentage of country A population to the world population
= Country A population /The world population
The percentage of country A population to the world population
= 226000000/7400000000
The percentage of country A population to the world population
= 0.03054
Now multiplying by 100
= 3.05%
The percentage of country A population to the world population is 3.05%
Given that,
As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million.Based on the above information, the calculation is as follows:
[tex]= 226000000\div 7400000000[/tex]
= 0.03054
= 3.05%
