Which expression is equal to (x+2)(x-4)/(x-4)(x+4)
A) x-2/x+4
B) x+4/x+2
C) x-2/x-4
D) x+2/x+4
Answer:
The expression equal to [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex] is [tex]\frac{(x+2)}{(x+4)}[/tex]
Option D is correct.
Step-by-step explanation:
We need to solve the expression [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex]
Since it is a fraction, and all terms are multiplying with each other we can cancel out common terms.
Since x-4 is both in numerator and denominator so, it will be cancelled out and we will get:
[tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}\\=\frac{(x+2)}{(x+4)}[/tex]
So, the expression equal to [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex] is [tex]\frac{(x+2)}{(x+4)}[/tex]
Option D is correct.
Answer:
D.) x+2/x+4

There are 1 × 1014 good bacteria in the human body. There are 2.6 × 1018 good bacteria among the spectators in a soccer stadium. About how many spectators are in the stadium? Express your answer in scientific notation.
Answer:
There are [tex]2.6\times 10^{4}[/tex] spectators in the soccer stadium.
Step-by-step explanation:
From this statement, we can calculate the number of spectators in a soccer stadium by dividing the amount of bacteria among the spectators in a soccer stadium by the amount of bacteria in the human body. That is:
[tex]x = \frac{2.6\times 10^{18}\,bacteria}{1\times 10^{14}\,bacteria}[/tex]
[tex]x = \frac{2.6}{1}\times \frac{10^{18}}{10^{14}}[/tex]
[tex]x = 2.6\times 10^{18-14}[/tex]
[tex]x = 2.6\times 10^{4}[/tex]
There are [tex]2.6\times 10^{4}[/tex] spectators in the soccer stadium.

Solve the system of equations algebraically.
5g+4k=10
-3g-5k=7
Answer:
k = -5
g = 6
Step-by-step explanation
1) First solve for k and plug that into the other equation to solve for g.
5g + 4k = 10
4k = -5g + 10
k = -5/4g + 2.5
2) Plug k into the other equation to solve for g
-3g - 5k = 7
-3g = 5k + 7
-3g = 5(-5/4g + 2.5) + 7 Use the distributive property
-3g = -6.25g + 12.5 + 7 Combine like terms and simplify
-3g = -6.25g + 19.5 Add 6.25g to both sides
3.25g = 19.5 Divide 3.25 from both sides to find g
g = 6
3) Now we take this g and plug it into the other equation to find k
(we could also just plug it into this equation as well)
5g + 4k = 10
5(6) + 4k = 10
30 + 4k = 10
4k = -20
k = -5.
If we really wanted to doube check this then we could plug the k value into the equation we used to find the g value...
-3(6) - 5(-5) = 7
-18 + 25 = 7
So yes, k = -5 and g = 6.

What is the y-intercept of the line 3x – 4y = 24?
Answer:
-4 becuase when you graph it the y intercepts at -4
Step-by-step explanation:
Answer:
y-intercept: (0,-6)
Step-by-step explanation:
To find the y-intercept of an equation you make x equal to 0 and we get the equation -4y=24 when we solve that equation by dividing by -4 from both sides and we get our y which is -6.

What is the measure of angle y?
Answer:
y =50°
Step-by-step explanation:
40°+90°+y = 180° {the sum of angle of triangle is 180°}
or, 130°+ y = 180°
or, y = 180°-130°
or, y =50°
The value of the measure of an angle y in a triangle would be 50 degrees.
Used the concept of angle in a triangle that states,
The sum of all three interior angles in a triangle gives 180 degrees.
Given that,
A triangle is shown in the attached figure.
Here, the triangle shown in the image is a right-angle triangle.
Hence, a measure of an angle = 90 degree
And, the second measure of an angle = 40 degree
So, the sum of interior angles in a triangle gives 180 degrees.
Hence,
40° + 90° + y = 180°
Solve for y,
130° + y = 180°
y = 180° - 130°
Therefore, the value of y is,
y = 50 degree

17) When filled to maximum capacity, a silo can hold about 4,000 cubic meters of corn. The radius of the silo is 8 meters. To the nearest meter, what is the approximate height (h) of the silo?
Answer: ion know i'm guessing 4
Step-by-step explanation: because it shows 8 at the top, so since it's full and it's 4,000 then that'll basically make 8 the 4000, so since 4 is half of 8 then we prolly have our answer right there
Answer: It would be 20
Step-by-step explanation: The formula for height would be h= v/pi r squared, just plug in the numbers
Before enrolling in a typing course, Maria could type 35 words per minute. At the end of the course, she could type 77 words per minute. Find the percent of increase in her typing rate
Given:
Initial speed of typing = 35 words per minute
At the end of the course her typing speed = 77 words per minute
To find:
The percent of increase in her typing rate.
Solution:
We know that,
[tex]\text{Percent of increase in her typing rate}=\dfrac{\text{New speed - initial speed}}{\text{Initial speed}}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=\dfrac{77-35}{35}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=\dfrac{42}{35}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=120\%[/tex]
Therefore, her typing rate is increased by 120%.

What is the value of x
Answer:
x=39
Step-by-step explanation:
First I try to find the angle measurements for the rest of the angles inside the triangle. I saw that the 68 degrees and I notice that it was vertical angles, meaning that the inside is also 68. I then notice that the 107 and the other unknown angle besides x must be 180 when adding up, so I can do 180-107=73. Now I know that that angle is 73 degrees I can find x by solving this equation 180=73+68+x, which the answer comes out to be 39. so x=39.

What is the graph?A graph, which is a mathematical representation of a network, describes the relationship between lines and points. A graph is made up of a few points and the arcs that connect them. Neither the location of the points nor the length of the lines matters.
Given that, the equation of a line is y=x+2.
Substitute x=0, 1, 2, 3, 4, 5 and 6 in the equation y=x+2, we get
y = 2, 3, 4, 5, 6, and so on.
So, the coordinate points are (0, 2), (1, 3), (2, 4), (3, 5) and (4, 6).
In the obtained graph, we got the points (0, 2), (1, 3) and (2, 4), they are accurate as we calculated.
Yes, the ordered pairs are accurate as estimated by our theoretical calculations.

if a triangular sail has a vertical height of 83 ft and horizantal length of 40 ft, what is the area of the sail?
Answer:
A = 1660 [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of the sail or a triangle is base times height
A = [tex]\frac{1}{2}[/tex](b x h)
Base is 40 ft (horizontal length)
Height is 83 ft (vertical height)
A = [tex]\frac{1}{2}[/tex](b x h)
A = [tex]\frac{1}{2}[/tex](40 x 83) = [tex]\frac{1}{2}[/tex](3320) = 1660 [tex]ft^{2}[/tex]
