Answer:
46 (23%)
Step-by-step explanation:
If 10% of x is 20, we can assume that 100% of x is 200. This is because since 10% is such a nice number to work with, we can simply add a zero to the end of it and the number. Now, we can see that 50% is 100 and 25% is 50. 20% is 40 and 10% is 20. 5% is 10 and 1% is 2. That being said, we need to do 50% + 3%. Which leaves us with 50 (25%) - 4 (2%). That being said, the answer is 46 (23%).

After swimming 80 feet below the surface of the water, a whale swims up 40 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water's surface.
A) The equation is -80 + (-40) = -120. The whale is 120 ft below the water's surface.
B) The equation is -80 + 40 = -40. The whale is 40 ft below the water's surface.
C) The equation is -80 + (-40) = -40. The whale is 40 ft below the water's surface.
D) The equation is -80 + 40 = -120. The whale is 120 ft below the water's surface.
Answer:
the answer is d
Step-by-step explanation:
he swims 80 feet below so thats gonna be a negative number. he then swims up 40 feet so you would be adding . so -80+ 40 = -120
The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)
What is equation?
Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.
Whale swims 80 ft below so it be a negative number.
Whale then swims up 40 ft so would be adding .
When the whale is 120 ft below the water's surface so it be a negative number.
-80+ 40 = -120
Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120

4 (3q-2) = 4q + 2q
Show your work
Answer:
8/6 or 1 1/3
Step-by-step explanation:
Step 1:
4 ( 3q - 2 ) = 4q + 2q Equation
Step 2:
12q - 8 = 4q + 2q Multiply
Step 3:
12q - 8 = 6q Combine Like Terms
Step 4:
12q = 6q + 8 Add 8 on both sides
Step 5:
6q = 8 Subtract 6q on both sides
Step 6:
q = 8 ÷ 6 Divide
Answer:
q = 8/6 or 1 1/3
Hope This Helps :)
Answer:
Hi there! The answer is q=4/3.
Step-by-step explanation:
First—Distrubute the 4 on each side of 3q-2. You should get 12q-8 on the left side of the equation.
Second— Combine like terms. You should see the 4q+2q obviously. Since they have the same letters, they should be combined Into 6q.
as a result you should have 12q-8 on the left side and 6q on the right side.
Switch 6q’s place with -8. But make sure you change the signs of negative and positives as you switch.
Now you should have 12q-6q=8.
Combine like terms again which will be 12q-6q Which will become 6q.
Now you should have 6q=8. divide 6 to both sides of the equation.
Since 6/6 = 1, there should be no coefficients stuck on the q.
when 8 is divided by 6, you should get 8/6.
WAIT YOU ARE NOT FINISHED YET!! YOU HAVE ONE MORE STEP AND YOU WILL HAVE ANSWER.
simplify 8/6 top and bottom divided by 2 each, then you should have 4/3.

Use compositions to verify that g and g^-1 are in fact inverses.
g(x): 1/x+2
g^-1(x): 1/x - 2
Answer:
as written there, they are not inverses
proof by counter example: since g(1) = 3 , but g^-1(3) = -5/3 != 1
Step-by-step explanation:
g(g^-1(x)) == x if they are indeed inverses
1/(1/x -2) + 2 = x/(1-2x) + 2 != x so, they are not inverses

Fiona is completing the square to solve the polynomial
equation.
What should be her first step?
x2 - 4x + 1 = 0
isolating the constant 1
O adding 4 to both sides of the equation
O isolating the second term, 4x
adding 1 to both sides of the equation
Answer:
isolating the constant 1
Step-by-step explanation:
The first step in solving the equation via completing the square is to isolate the constant.
What is completing the square method?The term completing the square method refers to one of the popular methods of solving quadratic equations that involves the addition of half of the square of the b term to both sides of the equation.
Given that an equation, x²-4x+1 = 0, we need to find the first step to solve this be using completing the square method,
So, according to the definition, we will add first isolate the constant,
Therefore,
x²-4x+1 = 0
x²-4x = -1
Now, we will add 4 to both the side,
x²-4x+4 = -1+4
(x+2)² = 3
x+2 = ±√3
x = √3-2 or x = -√3-2
Hence, the first step in solving the equation via completing the square is to isolate the constant.

Suppose that a number written as a decimal has an infinite number of non-repeating digits after the decimal point. What is this number called?
Oirational
natural
unnatural
rational
Hell yall
Answer:
Irrational
Step-by-step explanation:
The number is called an irrational number.
These numbers have some distinct properties. The number of numbers after the decimal point is infinite. What this means is that it does not terminate. It keeps on repeating.
Also, these numbers cannot be represented as a ratio of two integers i.e two whole numbers. This is because they keep on going without termination.
Lastly is that these numbers do not repeat after decimal. What I mean by this is that they do not keep repeating a particular number after the decimal point. For example in cases like 2.33333; these are infinite too, but they can be represented by the ratio of two whole numbers and in such cases, they are not irrational in their own respect
A food bank sends a truck with 400 pounds of food to each of five local food pantries every week, and receives a government surplus shipment of 3,200 pounds every other week. If it has 10,000 pounds of food on hand at the begining of July , how much will it have six weeks later?
Answer:
6,400
Step-by-step explanation:
The calculation is shown below:-
But before that find the total number of pound in five local bonds
= 400 × 5
= 2,000
Now the amount at six week later is
= Food pounds + 3 × number of pounds + 3 × suplus shipment
= 10,000 + 3 × 2,000 - 3 × 3,200
= 10,000 + 6,000 - 9,600
= 6,400
Therefore according to the given situation the correct answer is 6,400

Answer:
She used an average of (115/30) gigabytes of data per day
Step-by-step explanation:
To get the average data usage per day, we simply divide the total data used by the number of days
Mathematically, that will be

What is the translation?A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
Translation Rules:
When the shape is moved towards the left by k units, then replace x with x - k.When the shape is moved towards the right by k units, then replace x with x + k.When the shape is moved up by k units, then replace y with y + k.When the shape is moved down by k units, then replace y with y - k.From the translation rule, g(x)=f(x)−1 is f(x) translated 1 unit down.
The graph of g(x)is the graph of f(x) translated 1 unit down. Therefore, option C is the correct answer.
