What is the difference between a reactant and a product in a chemical equation? (Science question)
Answer:
At the end of the chemical reaction, reactants are usually consumed and are transformed into a new substance. On the other hand, products are end points of chemical reactions, and they are produced at the end of the process. In a chemical equation, reactants are commonly placed on the right side of the arrow.

− 1 − 9 + ( −15) + (− 8) + 3 =
Step-by-step explanation:
− 1 − 9 + ( −15) + (− 8) + 3 [B.O.D.M.A.S rule]
= − 1 − 9 −15 − 8 + 3
= 3 - 1 - 9 - 15 - 8 (First and last subtraction)
= 3 - 33
= -30(Ans)
Answer:
-30
Step-by-step explanation:
Well we don't necessarily have to follow pemdas right now, because there is only addition and subtraction, and they are on the same level and they don't matter which order they are used in.
So, with that being said, let's go step by step. I could've done an easier way, but for the sake of this question, I will do it a way that is a bit longer.
So, -1-9= -10.
For the next number, if there is a + and then a () and there is a negative number in the parenthesis, forget about the + and just subtract 15.
-10-15= -25
Same for the next number. -25-8= -33
-33+3= -30
The easier method is just combining the negative numbers and adding/subtracting them and then combining the positive numbers and adding/subtracting them, and then combining both results to get your answer.
Anyways, hope this helped you! If so, please leave a rating and a thanks, and let me know if I was correct! (hopefully brainliest, but up to you) Have a great day!!
Here is a rectangle all measurement are in centimetres the area is 48cm^2 find the value of y
Answer:
y = 3 cm
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
2x + 6 = 5x – 9 (opposite side of rectangle are equal)
2x + 6 = 5x – 9
Collect like terms
6 + 9 = 5x – 2x
15 = 3x
Divide both side by 3
x = 15 / 3
x = 5 cm
Next, we shall determine the length of the rectangle. This can be obtained as follow:
L = 2x + 6
x = 5 cm
L = 2(5) + 6
L = 10 + 6
L = 16 cm
Finally, we shall determine the value of y. This can be obtained as follow:
Length (L) = 16 cm
Width (W) = y =?
Area (A) = 48 cm²
A = L × W
48 = 16 × y
Divide both side by 16
y = 48 / 16
y = 3 cm
5. What is the value of x?
Answer:
5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
in a 30-60-90 triangle the ratio of sides, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2
you can set up a proportion like this to solve for 'x':
[tex]\sqrt{3}[/tex] / 1 = 15 / x
cross-multiply:
[tex]\sqrt{3}[/tex]x = 15
x = 15/[tex]\sqrt{3}[/tex]
rationalize the denominator by multiply top and bottom by [tex]\sqrt{3}[/tex]
you get 15[tex]\sqrt{3}[/tex] ÷ 3 which is 5[tex]\sqrt{3}[/tex]

Describe and correct the error in solving the following rational equation , plz help!!!!!
First of all, x cannot ever equal -1 because if it does then in the original equation you'd be dividing by 0, which is not possible. anything divided by 0 is undefined.
I think the error was in the second step: x(x+1) = 2(x+1) because they didn't need to go from the first step to there. I'm assuming they multiplied both sides of the equation with (x+1) to get rid of the fraction, but since both sides have (x+1) as the denominator the (x+1) would've cancelled out instead of multiplying with the numerator.
Correction:
[tex]\frac{x}{x+1} = \frac{2}{x+1}\\(\frac{x+1}{1}) (\frac{x}{x+1}) = (\frac{2}{x+1})(\frac{x+1}{1}) \\x = 2[/tex]
as u can see, in the second step of this correction, the (x+1)s on both sides cancel out so only the numerators remain.
Hope this helps!
Explain whether the graph represents a function.
Answer:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
Answer:
2 stalls
Step-by-step explanation:
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
1 stall = 4 bundles
4 bundles = 1 stall
11 bundles = x
Cross Multiply
4x = 11
x = 11/4
x = 2 3/4 stalls
The greatest number of stalls he can build is 2 stalls

A shipping container will be used to transport several 70-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23500 kilograms. Other shipments weighing 9700 kilograms have already been loaded into the container. What is the greatest number of 70-kilogram crates that can be loaded into the shipping container?
Subtract what has already been loaded from total amount allowed:
23500 - 9700 = 13,800
Divide the amount left by the weight of each crate:
13,800 / 70 = 197.14
They can load 197 crates.

in the diagram below of triangle C D E,F is a midpoint of C D and G is a midpoint of D E, if F G = 9x -59, C E = 34 - x, what is the measure of C E?
Answer:
Hey, I'm not sure if my assumptions were correct or not because there is no diagram. I assumed the triangle to be equilateral, the two lines are parallel and the height of the triangle is 1.
Step-by-step explanation:
Since the triangle is parallel*, we can just use ratio and proportion.
[tex] \frac{rise}{run} = \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ 1(9x - 59) = 0.5(34 - x) \\ 9x - 59 = 17 - .5x \\ 9x + 0.5x = 59 + 17 \\ 9.5x = 76 \\ x = \frac{76}{9.5} \\ x = 8[/tex]
Now that we had found the value of x, we will now substitute that to both equations to get the respective distances.
CE = 34 - x = 34 - 8 = 26
Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression
Complete question is;
Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression ¾(1440) + 295.25 + (-33.50) to find today's total sales. Is she correct? Explain.
Answer:
Nina is correct
Step-by-step explanation:
Today, ticket sales were three-fourths as much as yesterday.
Thus, it means today's ticket sales will now be; $¾(1,440) = $1080
Now, food sales were down by $33.50.
Thus, food sales for today is;
$295.25 - $33.50 = $261.75
Thus,total ticket sales for today is;
1080 + 261.75 = $1341.75
From the expression of Nina which is ¾(1440) + 295.25 + (-33.50) ;
When calculated it gives the same value we got as $1341.75.
This means that Nina is correct
(02.02 MC) Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees, where will point B' lie? (−1, 4) (1, −4) (4, −1) (−4, 1)
Answer:
(-1,4)
Step-by-step explanation:
Point B in the pre-image is at (-1,4).
If triangle ABC is reflected over the x‐axis, the y-coordinate changes to its negative value, thus we have the transformation:
Next, if the point (-1,-4) is reflected over the y‐axis, the x-coordinate changes to its negative, Thus, we have the transformation:
Finally, a rotation by 180 degrees will give the coordinates of B' as:
The point B' will lie in (-1, 4) [ the same place as B].
The coordinates of point B' are [tex](-1,4)[/tex]. So, the first option is correct.
Given:
The vertices of a triangle ABC are [tex]A(-2,1), B(-1,4)[/tex] and [tex]C(-4,5)[/tex].
Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.
To find:
The point B'.
Solution:
If a figure reflected over x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]B(-1,4)\to B_1(-1,-4)[/tex]
If a figure reflected over y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]B_1(-1,-4)\to B_2(-(-1),-4)[/tex]
[tex]B_1(-1,-4)\to B_2(1,-4)[/tex]
If a figure rotated 180 degrees about the origin, then
[tex](x,y)\to (-x,-y)[/tex]
[tex]B_2(1,-4)\to B'(-(1),-(-4))[/tex]
[tex]B_2(1,-4)\to B'(-1,4)[/tex]
So, the coordinates of point B' are [tex](-1,4)[/tex].
Therefore, the first option is correct.
