In 1916 the company's sales manager insisted that a laboratory be formed to carry out experiments and tests to ensure quality control so that salesmen would not be embarrassed by faulty products. The laboratory in time made possible the research and development necessary to produce new and improved items in response to problems experienced by sandpaper users.

Solve for m.
5 + 2m = 9
Answer:
m = 2
Explanation:
It’s two parts help meeee please
Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
Answer:
20
Step-by-step explanation:
The mistake is in using 160 as the answer. It isn't.
The angle is very small well under 90. It is acute.
The horizontal part of the angle is on 180 degrees of the protractor.
Therefore the angle size is 180 - 160 = 20 degrees.

Simplify:
3(8) ° . (3) -2
solve 8 + 7x = 14
solve y + (-12) = 10
Answer:First one is x=1
second is y=22
Step-by-step explanation:
Answer:
[tex]x = \frac{6}{7}[/tex] y = 22Step-by-step explanation:
For first equation:
Subtract 8 from each side, so it now looks like this: 7x = 6Divide each side by 7 to cancel out the 7 next to x. It should now look like this: [tex]x = \frac{6}{7}[/tex]For second equation:
Simplify: y - 12 = 10Add 12 to each side, so it now looks like this: y = 22I hope this helps!

The height above the surface of the Earth (in meters) of a rock thrown into the air at 10 m/s after x seconds is given by f(x)=−9.8x2+10x+1.5. On the surface of the moon, the height is given by g(x)=−1.6x2+10x+1.5. How much higher does the rock travel on the moon than on Earth? The rock travels about __ meter(s) higher on the moon than on Earth.
Answer:
Rock travels about 8.2x²meters higher on the moon than on the Earth.
Step-by-step explanation:
Expression showing the height of a rock thrown into the air at Earth is,
f(x) = -9.8x² + 10x + 1.5
Similarly, expression showing the height of rock thrown on the moon is,
g(x) = -1.6x² + 10x + 1.5
Difference in the height of the rock thrown on moon = g(x) - f(x)
= (-1.6x² + 10x + 1.5) - ( -9.8x² + 10x + 1.5)
= -1.6x² + 9.8x² + 10x - 10x + 1.5 - 1.5
= 8.2x²
Therefore, rock travels about 8.2x²meters higher on the moon than on the Earth.

You and your friend each purchase an equal number n of magazines. Your magazines cost $1.50 each and your friend's magazines cost $2 each. The total cost for you and your friend is $10.50. Write and solve an equation to find the number of magazines you purchased.
Given:
You and your friend each purchase an equal number n of magazines.
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Total cost = $10.50
To find:
The equation to find number of magazines you purchased.
Solution:
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Number of magazines purchased by you and your friend = n
Total cost = [tex]1.50n+2n[/tex]
It is given that total cost is $10.50.
[tex]1.50n+2n=10.50[/tex]
[tex]3.50n=10.50[/tex]
Divide both sides by 3.50.
[tex]n=\dfrac{10.50}{3.50}[/tex]
[tex]n=3[/tex]
Therefore, required equation is [tex]1.50n+2n=10.50[/tex] and the number of magazines purchased by you is 3.
-1/2y=1/2+5 what is the solution?
Answer:
-11
Step-by-step explanation:
-1/2y=1/2+5
- 1/2 y = 1+10 (by taking lcm)
2
[tex]\frac{-1}{2}[/tex] x 2y = 11
y = -11
[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]
[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]
[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]
[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]
[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]
[tex]y = \frac{ \: \: 22}{ - 2} [/tex]
[tex]y = - 11[/tex]
The value of y = -11
Therefore :-
[tex] \frac{ - 1}{ \: \: \:2} \times - 11 = \frac{1}{2} + 5[/tex]

h-(-2.22)=-7.851 solve for h
Answer:
[tex]\boxed {h = -10.071}[/tex]
Step-by-step explanation:
Solve for the value of [tex]h[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
[tex]h + 2.22 = -7.851[/tex]
-Subtract both side by [tex]2.22[/tex]:
[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]
[tex]\boxed {h = -10.071}[/tex]
So, the value of [tex]h[/tex] is [tex]-10.071[/tex].

In the figure, m<7 = 100. Find the measure of <9.
As < 7 and angle < 9 are alternate interior angles, their sum will be equal .
Which means :-
[tex] < \: 7 = < \: 9[/tex]
[tex] < 9 = 100°[/tex]
Therefore , the value of <9 is 100° .
The magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.
What are parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is ∠7 = 100°.
The lines u and t are parallel to each other. The alternate interior angles are equal in magnitude. From the figure it is clear that ∠7 and ∠9 are alternate interior angles. Therefore, we can say that ∠7 = ∠9 = 100°.
Therefore, the magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.

Answer:
5. m∠A = 26
6. m∠D = 118
7. m∠E = 43
8. m∠H = 85
Step-by-step explanation: complementary= 90 supplementary = 180
5. (2x - 8) + (4x +4) = 90
6x - 12 = 90
6x = 102
x = 17
m∠A = 2x - 8
m∠A = 2(17) - 8 = 26
6. (2x + 18) + (5x + 8) = 180
7x + 26 = 180
7x = 154
x = 22
m∠D = 5x + 8
m∠D = 5(22) + 8 = 118
7. (2x + 15) + (3x + 5) = 90
5x + 20 = 90
5x = 70
x = 14
m∠E = 2x + 15
m∠E = 2(14) + 15 = 43
8. (5x - 20) + (4x + 7 ) = 180
9x - 27 = 180
9x = 207
x = 23
m∠H = 4x -7
m∠H = 4(23) - 7 = 85
Find the slope of the line given two points:
(8, 10) and (-7, 14)
A
m = -15/4
B
m = -24/1
с
m = -4/15
D
m = 4/15
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8, 10) and (-7, 14)
The slope is
[tex]m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\ [/tex]
We have the final answer as
[tex] - \frac{4}{15} \\ [/tex]

Which equation represents the vertical asymptote of the graph?
There is a hidden electric fence of sorts where the graph slowly approaches this vertical line but never touches or crosses it. It might help to draw in a dashed vertical line through -8 on the x axis.
A vertical asymptote occurs when a division by zero error happens. For instance, the equation y = 1/(x+8) has a division by zero error when x = -8 since x+8 = -8+8 = 0 is in the denominator.

Gianna, Jada, and Brittney and a bunch of other friends had a horseshoe competition. Jada and Brittney were eliminated after two rounds because they were too busy texting but Gianna went onto round eight to win 47 pieces of gum. Later, she gave two to each of her friends. She only has 1 remaining. How many friends does she have?
Answer:
23 friends
Step-by-step explanation:
Let the number of friends she has = x
Total number of gum = 47 pieces
She gave 2 each to her friends, hence:
2x + 1 = 47
2x = 47 - 1
2x = 46
x = 46/2
x = 23
Therefore, the number of friends she has is 23
