Step-by-step explanation:
15 1/2+ 3/4=16 1/4
to add fractions what you want to do is this:
so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)
so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.
15+1 2/8=16 2/8
16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)
16 1/4
do the same with the other adding ones.
23 1/6+8 3/4=23 11/12
15 2/5+ 2 2/6= 17 11/15
now, do the same way as showed before but except subtract.
9/10 - 3/5 = 15/50
7 3/4 - 5 5/8 = 1/8
20 5/8= 1/8

The size of a white tablet is 0.000005 m and that of a red tablet is 0.0000275 m.Find their ratios and Compare their sizes
A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).
Therefore:
[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]
However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:
[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)
Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:
From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.
Hope this helps! :)

Find the value of x.
Answer:
x = 13
Step-by-step explanation:
Sum or interior angles of a triangle is 180,
6x + 19 + 5x - 15 + 3x - 6 = 180
6x + 5x + 3x + 19 - 15 - 6 = 180
14x + 19 - 21 = 180
14x - 2 = 180
14x = 180 + 2
14x = 182
x = 182 / 14
x = 13

3xyz + 7xyz + 9xyz
Answer:
19xyz
Step-by-step explanation:
First, let us just forget about the xyz at the end of each number. Now, we just have the simple addition problem 3 + 7 + 9. First. let us do 3 + 7, which gives us 10. Now, let us take our 10 and add the 9 to it. 10 + 9 is 19. Now, we can add our xyz back to the equation. Now, we have 19xyz. As we do not know anything about what x, y, or z equals, nothing further can be done with this equation. Therefore, the answer is 19xyz.
Hope this helps! :D

Evaluate the following integral:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given integral is
[tex]\rm :\longmapsto\:\displaystyle\int\rm \frac{ {x}^{e - 1} + {e}^{x - 1} }{ {x}^{e} + {e}^{x} } \: dx[/tex]
To evaluate this integral, we use Method of Substitution.
So, Substitute
[tex]\rm :\longmapsto\: {x}^{e} + {e}^{x} = y[/tex]
[tex]\rm :\longmapsto\: \dfrac{d}{dx}({x}^{e} + {e}^{x}) = \dfrac{d}{dx}y[/tex]
[tex]\rm :\longmapsto\: {ex}^{e - 1} + {e}^{x} = \dfrac{dy}{dx}[/tex]
[tex]\rm :\longmapsto\:e( {x}^{e - 1} + {e}^{x - 1}) = \dfrac{dy}{dx}[/tex]
[tex]\rm :\longmapsto\:({x}^{e - 1} + {e}^{x - 1})dx = \dfrac{dy}{e}[/tex]
So, on substituting all these values in above integral, we get
[tex]\rm \: = \: \displaystyle\int\rm \frac{dy}{e \: y} [/tex]
[tex]\rm \: = \:\dfrac{1}{e} \displaystyle\int\rm \frac{dy}{ y} [/tex]
[tex]\rm \: = \:\dfrac{1}{e}log |y| + c[/tex]
[tex]\rm \: = \:\dfrac{1}{e}log \bigg| {x}^{e} + {e}^{x} \bigg| + c[/tex]
Hence,
[tex]\rm :\longmapsto\:\boxed{\tt{ \displaystyle\int\rm \frac{ {x}^{e - 1} + {e}^{x - 1} }{ {x}^{e} + {e}^{x} } \: dx = \frac{1}{e}log \bigg| {x}^{e} + {e}^{x}\bigg| + c}}[/tex]

The speed of light is 299 792 458 m / s
Which decadic units can you round to so that only one non-zero digit is produced?
Answer:
299,792,460
Step-by-step explanation:
just round to the nearest 10th
Answer:
The speed of light is exactly 299,792,458 m/s because that is how a meter is defined. A meter is defined as the distance light travels in 1/299792458 seconds in vacuum. Why was this particular number chosen? To keep the definition of meter consistent with the old standard which was an actual physical bar. The length of this bar was arbitrary though.

Write the equation of a line perpendicular to 5x−9y=−8 that passes through the point (−5,8).
Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1

B.
Line segment L'M' has a slope of 2, and does not pass through point H.
C.
Line segment L'M' has a slope of 2, and passes through point H.
D.
Line segment L'M' has a slope of 6 and passes through point H.
Answer D.
Step-by-step explanation:
D.
Line segment L'M' has a slope of 6 and passes through point H.
Given that line segment LM is dilated by a scale factor of to form L'M'. Statement D). is true.
What is dilation of a line segment?The dilation of a line segment is longer or shorter in the ratio given by the scale factor. If the scale factor is greater than 1 (k > 1), the image will be larger than the pre-image, making the segments (sides) of the image longer than the corresponding sides of its pre-image (an enlargement).
When a line segment gets dilated, it gets longer or shorter. But, the slope does not change. Also, the center of dilation which lies on the line segment, stays on the line only. Thus, D). is true.

Find the value of each variable
Answer:
x = 11
Step-by-step explanation:
1. Because this is a straight angle, (11x + 7)° and (5x - 3)° add up to 180°.
[tex]11x+7+5x-3=180[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](11x+5x) + (7-3) = 180[/tex] [tex]16x + 4 = 180[/tex]Step 2: Subtract 4 from both sides.
[tex]16x + 4 - 4 = 180 - 4[/tex] [tex]16x = 176[/tex]Step 3: Divide both sides by 16.
[tex]\frac{16x}{16} = \frac{176}{16}[/tex] [tex]x = 11[/tex]Therefore, x = 11! I hope this helped you.
