Step-by-step explanation:
She bought 1.2 bitcoins in $400.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that,
Number of bitcoins in $1 USD = 0.003
The to find the number of bitcoins in $400
We just multiply 400 by the number of bitcoin bought in 1 $1 USD
Therefore,
The number of bitcoin she bought in $400 is,
= 400 x 0.003
= 1.2
Thus,
Number of bitcoins in $400 = 1.2

The amount of money in Alexander’s account is, = 4000 − 70, where is the amount in dollars and is the time in weeks.
a) Which variable is independent and which is dependent?
Answer: Dependent is -70x and independent is 4000
b) In which week will there be $1701 in the account?
Answer:
y=4000-70(x)
1701=4000-70(x)
-70x=1701-4000
-70x= -2299
x=-2299/-70
x=2299/70
x=32.843
x=33
c) How much will the amount in Alexander’s account change if the time increases by 15 weeks?
Answer:
y=4000-70(x)
y=4000-70(15)
y=2950
Answer:
yes you are correct
Step-by-step explanation:
The answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950
What are dependent and independent variables?The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Given that, The amount of money in Alexander’s account is, y = 4000 − 70x, where y is the amount in dollars and x is the time in weeks.
a) Here, y is the dependent variable as it depends on the value of x, and x is the independent value.
b) We have, total amount = $1701
Therefore, put y = $1701
$1701 = 4000 − 70x
70x = 2999
x = 32.84 ≈ 33 weeks
c) In 15 weeks the amount will be =
y = 4000 - 70(15)
= $2950
Hence, the answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950

1) Find the length of point A(-3,1) and B(2,6). Leave your
answer in RADICAL FORM ONLY.
Answer: The length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .
Step-by-step explanation:
We know that the distance between the two points (a,b) and (c,d) is given by :-
[tex]d=\sqrt{(a-c)^2+(b-d)^2}[/tex]
Given points = A(-3,1) and B(2,6)
Therefore the distance between the points A(-3,1) and B(2,6) is given by :-
[tex]d=\sqrt{(-3-2)^2+(1-6)^2}\\\\\Rightarrow\ d=\sqrt{(-5)^2+(-5)^2}\\\\\Rightarrow\ d=\sqrt{25+25}\\\\\Rightarrow\ d=\sqrt{50}\\\\\Rightarrow\ d=\sqrt{25\times2}\\\\\Rightarrow\ d=\sqrt{5^2\times2}\\\\\Rightarrow\ d=5\sqrt{2}\text{ units}[/tex]
Hence, the length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .

Megan has two boxes with the dimensions shown. She wants to use the box with the greater volume to ship a gift to her friend. Which box should Megan use? Explain.
Answer:
384 3/4
341 1/4
box A
Step-by-step explanation:
The volume of the box is given by the formula:
Volume = length * width * height
The volume of the box A is:
Volume_A = 9.5 * 3 * 13.5 = 384.75 cm3 = 384 3/4 cm3
The volume of the box B is:
Volume_B = 10 * 3.25 * 10.5 = 341.25 cm3 = 341 1/4 cm3
The volume of the box A is greater than the volume of the box B, so Megan should use the box A

The athlete drink 16 ounces of water every two hours starting at 7:30 AM and continuing for the next 14 hours. A) how many quarts did the athlete consume? B) how many pints of water did the athlete consume?
When the athlete drink 16 ounces of water every two hours for the next 14 hours,
(A) The athlete consumes 3.5 quartz of water.
(B) The athlete consumes 7 pints of water.
Conversions(1) Ounce to Pints16 ounces = 1 pint
(2) Quarts to Ounces1 quart = 32 ounces.
(A) Calculation for the water consumed by athlete in quarts:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Covert the 16 ounces of water in quarts
= 16/ 32
=1/2
The total quantity of water consumed in quarts is
= 7×(1/2)
= 3.5 quarts
Thus, the amount of water consumed by athlete in entire 14 hours is 3.5 quarts.
(B) Calculation for the water consumed by athlete in pints:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Convert 16 ounce of water into pint

3(2c)
3+2c
2+2c
Answer:
3+2c
Step-by-step explanation:
To translate the phrase into an algebraic expression, you have to analyze the information provided. Three dollars more than twice the cost of a bowl of soups means that given that c is the costs of a bowl of soup, you have to multiply c for 2 as the phrase says twice the cost. Also, it says three dollars more which means that you have to add 3. According to this, the expression is: 3+2c.

100pts: What is the slope of the following curve at x = n, for an arbitrarily chosen integer n?:
y = 3x^2 - 37x + 6
Answer:
6n -37
Step-by-step explanation:
The slope would be the derivative of the function
dy/dx = 6x - 37 evaluated at the point n
dy/dx = 6n -37
Answer:
6n - 37
Step-by-step explanation:
The derivative of the function f(x) gives the gradient (slope) of the tangent to the graph of y = f(x) at the point (x, y).
Given:
[tex]y=3x^2-37x+6[/tex]
Therefore, the gradient (slope) of the given curve at x is:
[tex]\implies \dfrac{dy}{dx}=2 \cdot 3x^{2-1}-37x^{1-1}+0[/tex]
[tex]\implies \dfrac{dy}{dx}=6x-37[/tex]
To find the slope, simply substitute x for n:
[tex]\implies 6n-37[/tex]

Zack needs $299.99 to buy the new bike he wants. He has saved $150 so far toward the new bike. From this week on, he will save $12.50 per week toward the new bike. Ten weeks from now, how much more money will he still need to save to buy the bike?
$24.99
$29.99
$127.49
$137.49
Answer:
The answer is $24.99
The solution is Option A.
The equation of line is y = 12.5x + 150 , where x is the number of weeks
The amount Zack needs after 10 weeks to buy the bike is $ 24.99
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The price of the bike Zack needs to buy = $ 299.99
The initial amount with Zack = $ 150
The amount Zack saves in a week = $ 12.50
The number of weeks = x
The amount Zack saves in x weeks = 12.5x
So , the total amount with Zack after x week is given by the equation ,
Total amount with Zack after x week y = amount Zack saves in x weeks + initial amount with Zack
Substituting the values in the equation , we get
Total amount with Zack after x week y = 12.5x + 150
Now , after 10 weeks , the amount with Zack is
Substitute the value of x as 10 in the equation , we get
y = 12.5x + 150
y = 12.5 ( 10 ) + 150
y = 125 + 150
y = $ 275
Now , the amount left to buy the bike = price of the bike Zack needs to buy - amount with Zack after 10 weeks
Substituting the values in the equation , we get
Amount left to buy the bike A = $ 299.99 - $ 275
Amount left to buy the bike A = $ 24.99
Therefore , the value of A is $ 24.99
Hence , the amount Zack needs is $ 24.99
