Answer:
D. The amount of NO2 and SO2 would increase.
Step-by-step explanation:
This is an exothermic reaction as Heat is among the products. Increasing the temperature would lead to more products in the reaction system. In order for the system to annul this change, more reactants would be formed.
The correct option is;
D. The amount of NO2 and SO2 would increase.
Tools of Geometry: Question 10 Quadrilateral ABCD has vertices A = (0, 4), B = (0, 3), C = (3, 0), and D = (3 ,4). Quadrilateral A'B'C'D' is formed when quadrilateral ABCD is reflected over the x-axis. What are the coordinates of quadrilateral A'B'C'D' ? A' = (-4, 0), B' = (-3, 0), C' = (0, 3), and D' = (4, 3) A' = (0, -4), B' = (0, -3), C' = (-3, 0), and D' = (-3, -4) A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4) A' = (0, 4), B' = (0, 3), C' = (-3, 0), and D' = (-3, 4)
9514 1404 393
Answer:
(c) A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)
Step-by-step explanation:
Reflection over the x-axis negates the y-coordinate only. The appropriate choice is ...
A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)

Polygon E’F’G’H’
is a dilation image of the polygon
EFGH
What is the scale factor of the dilation?
A.3
B.6
C.12
D.1/3
Answer:
The scale factor of the dilation is 3 ⇒ A
Step-by-step explanation:
If a polygon dilated by a scale factor k, then the ratio between its sides and the corresponding sides of its image equals k The length of a vertical segment is the difference between the y-coordinates of its endpointsIn the given figure
∵ EFGH is a polygon
∵ E = (-2, 1), H = (-2, -1)
∵ EH is a vertical side
→ By using the 2nd rule above
∴ The length of EH = 1 - (-1) = 1 + 1
∴ The length of EH = 2
∵ E'F'G'H' is its image after dilation by scale factor k
∵ E' = (-2, 5), and H' = (-2, -1)
∵ E'H' is a vertical side
∴ The length of E'H' = 5 - (-1) = 5 + 1
∴ The length of E'H' = 6
→ By using the 1st rule above
∴ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{E'F'}{EF}[/tex] = [tex]\frac{H'G'}{HG}[/tex] = [tex]\frac{F'G'}{FG}[/tex] = k
∵ [tex]\frac{E'H'}{EH}[/tex] = k
∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]
∴ [tex]\frac{E'H'}{EH}[/tex] = 3
∴ k = 3
∴ The scale factor of the dilation is 3
what does 8+2y-5x+y=x-1
The value of x is 1/2y+3/2
Answer:
y = 2x - 3
Step-by-step explanation:
8 + 2y - 5x + y = x - 1
3y = 6x - 9
y = 2x - 3
slope is 2, y-intercept is -3
Can somebody help me out with thisss ?????
===================================================
Explanation:
The combination of angle x and the 93 degree angle forms x+93. This obtuse angle is congruent to 130 because these two angles are alternate interior angles and because line L is parallel to line M.
So,
x+93 = 130
x+93-93 = 130-93 .... subtracting 93 from both sides
x = 37

The Choir Booster Club had a budget of $1,500 at the start of the school year. They spend $225.30 on t-shirts, $482.25 on lost uniforms, and $135.68 on a holiday party. How much does the booster club have left in their budget?
Answer:
$656.77 is left
Step-by-step explanation:
-$1,500 budget
Spends: $225.30, $482.25, 135.68.
Now subtract all these values with 1,500.
1500 - 482.25 - 225.30 - 135.68 = 656.77

Answer:
Step-by-step explanation:
Median: First write in ascending order. If number of data's is odd, median is the middle data.
If number of data's is even, then median = average of n/2th and (n+2)/2th term.
1) 1 , 3 , 5 , 5 , 6
Median = 5
2) 3,4,10,2,1
Ascending order: 1,2,3,4,10
Median = 3
3) 4, 5,7,11
Median = (5+7)/2 = 12/2 = 6
4) 1,1,2,6
Median = (1+2)/2 = 3/2 = 1.5
5) 2,2,3,3,,5,7
Median = 3+3/2 = 6/2 = 3
6)1,2,4,6,7,7
Median = (4+6)/2 = 10/2 = 5
7) 2,2,3,6,7,8
Median = (3+6)/2 = 9/2 = 4.5
8)1,2,3,14,17,18
Median = (3+14)/2 = 17/2 = 8.5
Mean= Sum of all the items÷ number of items
1)Mean = (1+2+3+2)÷4 = 8÷2 = 4
2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3
3)Mean = (5+4+6+1)÷4 = 16÷4 = 4
4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4
5)Mean =(10+11+9+12+8)÷5=50÷5 = 10
6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4
7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1
8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5
Answer:
Median
1) 5
2) 3
3) 5+7=12/2=6
4)1+2=3/2=1.5
5)3+3=6/2=3
6) 4+6=10/2=5
7) 3+7=10/2=5
8)14+3=17/2=8.5
Mean
1) 2
2) 3
3)4
4)4
5) 10
6) 0
7) 1
8) 4.5
Step-by-step explanation:
Median is the middle number, make sure the list of in order from smallest to highest.
2) 1, 2, 3, 4, 10
if you have two numbers in the middle add them together then divide by 2
4) 1, 1, 2,6
5)2, 2, 3, 3, 5, 7
6) 1, 2, 4, 6, 7, 7
7)2, 2, 3, 7, 6,8
8)1, 2, 3, 14, 17, 18
Mean is when you add all the numbers together and divide by how many there are.
1) 1+3+2+2=8/4=2

Lake Michigan is one of five great lakes in north america.In summertime, lake Michigan recedes about 1/4 foot per hour. Lake Michigan is about 279 ft. In depth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, a possible question is "calculate the depth of the lake after certain number of hours (say 2 hours)"
Given
[tex]Rate = \frac{1}{4}ft/hr[/tex]
[tex]Depth = 279ft[/tex]
First, we calculate the depth receded.
If the rate is 1/4ft per hour
Then
The Depth receded in 2 hours is:
[tex]Receded = \frac{1}{4} * 2[/tex]
[tex]Receded = \frac{2}{4}[/tex]
[tex]Receded = 0.5ft[/tex]
The new depth is then calculated as:
[tex]New\ Depth = 279ft - 0.5ft[/tex]
[tex]New\ Depth = 278.5ft[/tex]
HELP ASAP WILL MAKE BRAINLEST
Answer: the last one
Step-by-step explanation:
um so the set begins with 40 and ends with 100 (look at that on the number line)
and so the median is essentially that middle line in the box, which is around 80
i assume yk how to calculate medians so I calculated the median of the first and the last answer
the first one was like 70, and the last one was like 78.9 which is close enough to 80
so i think its the last one
Answer:
It is answer number four.
Step-by-step explanation:
40 and 100 represent the outliers so both numbers must be included.
80 must also be included as it is the mean or average test grade.
What is the equation of the line that passes through the points 1/2/3 and (-1,-1
a.y=-6x+5
b.Y=5/6X-1/6
C.Y=2/3X+1/5
D.y=6/5x+1/5
Answer:
(1, 2/3) (-1, -1) are the points. use the slope formula to find the slope y2-y1/x2-x1
(-1 - 2/3) / (-1 -1) (answer both sides of the division side)
-5/3 / -2 (divide)
slope = 5/6 (the slope)
plug in values you know into point-slope form (y -y1) = m(x-x1)
y - (-1) = 5/6 (x - (-1) (i chose the easier point to plug in. two neg. make a pos. )
y +1 = 5/6 (x +1) (use the distributive property)
y +1 = 5/6x+5/6 (subtract 1 from both sides)
y = 5/6x - 1/6 or B (this is the equation)

Answer:
[tex]b+1\\b+2\\b+(b+1)+(b+2)=24[/tex]
Step-by-step explanation:
If [tex]b[/tex] represents the youngest brother's age, the second oldest brother's age can be written as [tex]b+1[/tex] and the third can be written as [tex]b+2[/tex], since they're all consecutive.
The sum of all their ages is then [tex]b+(b+1)+(b+2)[/tex] which is equal to [tex]24[/tex], as given.

Answer: A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.
Step-by-step explanation:
find the angle p (add a explanation too)
Step 1: Find the sum of the interior angles
Use this formula: 180 x (n - 2)
n is the number of sides of the polygon
Work:
180 x (4 - 2)
180 x 2
360
Step 2: Find the angle right above the 94 degree angle
The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.
Work:
360 - 94
266
Step 3: Set up an equation to find the missing angle p
We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.
360 = 12 + 75 + 266 + p
360 = 353 + p
p = 7 degrees
Does this answer make sense?
Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.
Hope this helps!! :)

HELP!!!What is the length of BC in the right triangle below
Answer: 39
Step-by-step explanation:
D. 39
Explanation:you use the pythagorean theorem which is [tex]a^{2}+b^{2} = c^{2}[/tex]
if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).
so your equation will look like this:
[tex]15^{2} + 36^{2} =c^{2}[/tex]
Solving For The Length Of BC1. [tex]15^{2} + 36^{2} =c^{2}.[/tex] (solve for [tex]15^{2} and 36 ^{2}[/tex])
2. C= 225+1296 (add)
3. C= 1521 (find the square root of 1521)
4. [tex]\sqrt{1521} = 39[/tex]
Therefore, 39 is your answer

Answer:
x = 10√3
Step-by-step explanation:
The Pythagorean theorem tells you ...
FB^2 = BC^2 +CF^2
FA^2 = FB^2 +BA^2
Substituting for FB^2, we have ...
FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2
FA^2 = 3x^2
FA = x√3 = 30 . . . . take the square root and substitute for FA
x = 30/√3
x = 10√3
