Step-by-step explanation:
The reaction NaCL + AgNO3 → NaNO3 + AgCL is a replacement reaction.
The given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.
When elements swap positions in compounds, a replacement reaction takes place. Ions are involved in this kind of response. In most cases, more reactive elements take the place of less reactive ones. When one element replaces another in a compound, it is known as a single replacement reaction.
Here,
In the given chemical reaction, Na is replaced by Ag, As per the above definition of the replacement reaction.
NaCl + AgNO3 = Na- cl + Ag-NO3 → NaNO3 + AgCl
Thus, the given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.

A paper popcorn cone measures 4 inches in diameter and is 9 inches high. What is the volume of popcorn that can be contained within this cone? Use 3.14 for pi. Round your answer to the nearest hundredth.
answer choices
41.90 cubic inches
37.68 cubic inches
39.45 cubic inches
40.23 cubic inches
Answer:
The formula for finding volume of a cone is (in this case),
V=(3.14)(r^2)(h/3)
With this formula in mind, you would simply substitute in.
V=(3.14)(2^2)(9/3)
You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.

I would find A for you too but there is no graph! But for example the slope formula is (y2-y1)/(x2-x1)! You would take any big y number and use it as your y2 go up one use it as your y1 subtract it that’s your numerator. Next take your big x2 across from your y2 and then use the one across from y1 and subtract those that’s your denominator!
Alicia is solving the equation 2.3 x minus 1.6 = 8.8 minus 2.9 x. Which equations represent possible ways to begin solving for x? Check all that apply.
2.3 x minus 10.4 = negative 2.9 x
5.2 x minus 1.6 = 8.8
Negative 6.5 x minus 1.6 = negative 2.9 x
2.3 x + 1.3 = 8.8
2.3 x = 10.4 minus 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+ 1.6 +1.6
2.3 x = 10.4 - 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
-8.8 - 8.8
2.3 x - 10.4 = 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+2.9 x + 2.9 x
5.2 x -1.6 = 8.8

he graph below represents the price of sending video messages using the services of a phone company. What is the constant of proportionality? A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The values on the y axis are 0, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240. Points are shown on ordered pairs 0, 0 and 2, 48 and 4, 96 and 6, 144 and 8, 192. These points are connected by a line. The label on the x axis is Video Messages Sent. The label on the y axis is Price in cents. 12 24 46 48
Answer:
24.
Step-by-step explanation:
Basically constant of proportionality is a ratio.
We take two points, we'll take the order pair (2,48)
It will always be y/x so y is 48 and x is 2
48/2 - now we simplify

On a coordinate plane, the x-axis is labeled bananas and the y-axis is labeled cost in dollars. The line goes through points (1, 0.27) and (2, 0.54).
Which statement about the graph is true?
The number of bananas is the independent variable, and the cost in dollars is the dependent variable.
The point (1.35, 5) is on the line.
The number of bananas is graphed on the y-axis, and the cost is graphed on the x-axis.
The two variables are the number of bananas and the cost of one banana.
Answer:
I think it is A correct me if I am wrong
Step-by-step explanation:
The statement first "The number of bananas is the independent variable, and the cost in dollars is the dependent variable" is correct.
What is a line graph?A line graph is a graph made up of segments of straight lines that connect the depicted data points.

Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.

May:
Inez:
Carolyn:
Answer:
May = $23.25 Inez = $2325 Carolyn = $232.50
Step-by-step:
May makes that much because it says it in the problem. Inez makes that much because 23.25 times 100 equals 2325. Finally one tenth of 2325 is 232.5
Answer:
may makes 23.25
inez make 2, 325
