Answers
Answer:
a. 4.85
Step-by-step explanation:
im right
? = a+b
a = 3
(3+b)/3=3/b
b= -4.85 or 1.85
it cant be negive.
so ? = 3+1.85 = 4.85

Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder to the flour. Laura knows that 1 cup of that particular chocolate powder has a mass of 128 grams. She added two over three of a cup of chocolate powder to the flour. Should Laura add more chocolate powder to make the exact recipe or did she go over and by what amount?
She went over by one over three of a cup
She needs to add one over three of a cup
She needs to add one over six of a cup
She went over by one over six of a cup
Answers
1 cup of that particular chocolate powder has a mass of 128 grams: 1c = 128g
64 grams of chocolate powder is x cups.
1c = 128g
x = 64g
1c : 128 g = x : 64g
x = 1c : 128 g * 64 g
x = 0.5 c
64 grams of chocolate powder is 0.5 cups = 1/2 cups
She added two over three of a cup of chocolate powder: 2/3 cups
She need to add 1/2 cups: 1/2 = 3/6 cups
She added 2/3 cups: 2/3 = 4/6 cups
So she added 4/6 - 3/6 = 1/6 cups more.

Solve the equation below for y.
8x - 2y = 24
A. y= 4x - 12
B. y= 12 - 4x
C. y = 8x - 24
D.y = 4x - 8
Answers
Because 8x - 2y = 24 is equal to -2y = -8x + 24 is equal to y = 4x - 12.
The given equation, when solved for y gives y = 4x - 12.
Hence, option A is correct.
Given is an equation 8x - 2y = 24, we need to solve for y.
To solve the equation for y, you need to isolate y on one side of the equation.
Let's do that step by step:
Start with the original equation:
8x - 2y = 24
Get rid of the constant term on the left side by subtracting 8x from both sides:
-2y = -8x + 24
Now, we want to solve for y, so we need to get rid of the coefficient of y (-2).
To do that, divide both sides by -2:
y = (-8x + 24) / -2
Simplify the right side of the equation:
y = -8x / -2 + 24 / -2
Simplify further:
y = 4x - 12
So, the solution for y is:
A. y = 4x - 12

Which polynomial expression represents the area of the outermost square tile, shown below?

x2 + 9x + 6
x2 + 6x + 9
x2 − 6x + 9
Answers
Answer:
The correct answer is C, "x2 + 6x + 9."
Step-by-step explanation:
I just got it correct on the test.
Final answer:
To find the area of a square tile with sides of length x + 3, we square the binomial, resulting in the polynomial expression x² + 6x + 9, which represents the area of the square tile.
Explanation:
The question asks which polynomial expression represents the area of a square tile with sides of length x + 3. To find the area of a square, you multiply the length of one side by itself. In this case, the length of each side of the square is (x + 3), so the area of the square is (x + 3)(x + 3), or (x + 3)².
To expand this expression, we use the formula for squaring a binomial: (a + b)² = a² + 2ab + b². Applying this formula to our expression, we get:
a = x
b = 3
(x + 3)² = x² + 2(3)x + 3²
(x + 3)² = x² + 6x + 9
Therefore, the correct polynomial expression that represents the area of the square tile is x² + 6x + 9.

The table below shows the temperature (in °F) t hours after midnight in Phoenix on March 15. The table shows values of this function recorded every two hours.
Estimate the value of T′(8). Give units in your answer.
What is the meaning of T′(8)?
t 0 2 4 6 8 10 12 14
T 73 73 70 68 73 80 86 89
Answers
We need to estimate the value of T'(8) and then we need to give the meaning of this value. Since we have a table and not an expression of a function our goal is to find the Average Rate of Change between two points.
For a nonlinear graph whose slope changes at each point, the average rate of change between any two points [tex](x_{1},f(x_{1}) \ and \ (x_{2},f(x_{2})[/tex] is the slope of the line through the two points. So:
[tex]ARC=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}} =\frac{Change \ in \ y}{Change \ in \ x}=m_{sec}[/tex]
1. Estimated value of T′(8).
T'(8) means the derivative of the function T(t) when t = 8 hours. So, we can estimate this value using the average rate of change:
[tex]ARC=\frac{T(8)-T(6)}{8-6} =\frac{73-68}{8-6}=\frac{5}{2} \ degrees \ per \ hours[/tex]
2. The meaning of T′(8)
This means the average temperature after midnight in Phoenix on March 15, from t = 6 to t = 8 hours, that is, for each hour the temperature rises 5/2 degrees on the Fahrenheit scale. The points have been plotted in the Figure bellow.
The rate of change of the temperature is 3 degrees Celsius per hour. This response means that temperature has an instantaneous increase rate of 3 degrees Celsius per hour at [tex]t = 8\,h[/tex].
We can estimate the rate of change of the temperature, in degrees Celsius per hour, by calculating the average of two consecutive secant lines, whose expression is presented below:
[tex]T'(t) \approx \frac{1}{2}\cdot \left[\frac{T(t+\Delta t)-T(t)}{\Delta t} + \frac{T(t)-T(t-\Delta t)}{\Delta t} \right][/tex] (1)
If we know that [tex]\Delta t = 2[/tex], [tex]T(6) = 68[/tex], [tex]T(8) = 73[/tex] and [tex]T(10) = 80[/tex], then the estimated value of the rate of change of the temperature is:
[tex]T'(8) = \frac{1}{2}\cdot \left[\frac{80-73}{2}+\frac{73-68}{2} \right][/tex]
[tex]T'(8) \approx 3\,\frac{^{\circ}C}{h}[/tex]
The rate of change of the temperature is 3 degrees Celsius per hour. This response means that temperature has an instantaneous increase rate of 3 degrees Celsius per hour at [tex]t = 8\,h[/tex].
