Answer:

m = [tex]\frac{l}{v-u}[/tex]

Step-by-step explanation:

l = mv-mu (factor out m from mv and mu)

l = m(v-u) - (divide both sides by (v-u))

l/v-u =m

Answer:

V=πr2h

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

you add 1+1 and then 21

63degrees

Step-by-step explanation:

there are multiple ways to do this

for one, angle a = angle e (corresponding angles)

angle f + angle e = 180 degrees (angles on a straight line)

angle f = 180 degrees - angle e where angle e = angle a = 117degrees

so angle f = 63 degrees.

Answer:

x = 105

Step-by-step explanation:

The angles of a triangle add to 180 degrees

Let x be the third angle

55+20 +x =180

75 +x = 180

x = 180-75

x = 105

Answer:

third triangle=105 degrees

Step-by-step explanation:

Three angles of a triangle always add up to 180. Therefore the equation is 55+20+x=180. Solving for x we get x= 105

Answer: 10 - 30y - 5w

Step-by-step explanation:

Multiply each value of the first parenthesis to -5. Start with -2 (10), then 6y (-30y), and lastly w (-5w). Combine all the terms in order.

Answer:

A because y=-5

Step-by-step explanation:

Answer:

y > -3

Step-by-step explanation:

I will assume the sign you are missing is ">"

5(y + 6) + 2y > 9

~Simplify left side

5y + 30 + 2y > 9

~Combine like terms

30 + 7y > 9

~Subtract 30 to both sides

7y > -21

~Divide 7 to both sides

y > -3

Best of Luck!

Answer:

3y⁵√2

Step-by-step explanation:

Answer:

A. y = -1/2x+2

Step-by-step explanation:

You can plug in the point (-2,3) into all the equations in the choices to check which one is true. If we plug in the point (-2,3) into the 1st equation:

Answer:

x=416

Step-by-step explanation:

just did it its super fast problem to solve.

Step-by-step explanation:

Cross multiply

15x = 1560 x 4

15x = 6240

Divide both sides by 15

Therefore x = 416

9.1 kilograms

Step-by-step explanation:

9+.1 = 9.1 kilograms

Answer: P: (-3, -1), Q: (2, -1), R: (1, 2), S: (-3, 2)

Step-by-step explanation: the way I think about it is you have to run before you jump, so the third one let’s say, you have to “run” to 1, and then “jump” to 2. Now let’s take the first one, it’s the exact same thing just in the opposite direction, you “run” back to -3 and then “fall” to -1. Now let’s take the second one, first you would “run” to 2 and then “fall” (because it’s a negative) to -1, and if it was a negative first and then a positive, it would just be the opposite of the one O just explained

Answer:

10

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

four increased by the product of three and two

first we know were adding

+ 4

and multiplying

3 x 2

we don't have to do anything with parenthesis cause it's in order

4 + 3 x 2

or it could be flipped

3 x 2 + 4

now do the math

3 x 2 = 6

6 + 4 = 10

Answer:

6x(3x + 1)(x - 7) .

Step-by-step explanation:

First look for the greatest common factor of the 3 terms.

It is 6x, so

18x^3 – 120x^2 – 42x

= 6x(3x^2 - 20x - 7)

Now we look to factor the quadratic expression in the parentheses:

Use the 'ac' method:

The first and last coefficients are multiplied

3 * -7 = -21.

We look for 2 numbers whose product is -21 and whose sum is -20:

They are -21 and + 1 , so we write:

6x(3x^2 - 21x + 1x - 7)

= 6x [ (3x(x - 7) + 1(x - 7)]    Note that x - 7 is common, so:

= 6x(3x + 1)(x - 7)  Answer

Answer:

What is the measure of it doesn't show anything

Answer:

95 m

Step-by-step explanation:

Answer: Length: 95 meters.

Step-by-step explanation:

The perimeter of a rectangle is calculated with the formula:

                   P = 2(L + W)

                360 = 2(L + 85)

   Divide both sides by 2

          360 ÷ 2 = (L + 85)

                180  =  (L + 85)

    Subtract  85  from 180

                 180 - 85

                  97 = L  

Answer:

64 degrees

Step-by-step explanation:

The measure of the exterior angle should be that same as the measures of the two remote interior angles. The remote interior angles are 37 & 27, so when you add them together, you get 64.

Hope this helps :-)

==========================================================

Explanation:

The stem and leaf plot shows we have the following data items

{56, 67, 67, 69, 72, 74, 77, 77, 78, 81, 82, 82, 83, 84, 88, 90, 92, 93, 94}

Cross off the outermost items.

So cross off the first and last items to get this smaller set

{67, 67, 69, 72, 74, 77, 77, 78, 81, 82, 82, 83, 84, 88, 90, 92, 93}

Repeat that process again

{67, 69, 72, 74, 77, 77, 78, 81, 82, 82, 83, 84, 88, 90, 92}

Repeat again

{69, 72, 74, 77, 77, 78, 81, 82, 82, 83, 84, 88, 90}

Do so another time. We keep going til we get 1 or 2 values

{72, 74, 77, 77, 78, 81, 82, 82, 83, 84, 88}

{74, 77, 77, 78, 81, 82, 82, 83, 84}

{77, 77, 78, 81, 82, 82, 83}

{77, 78, 81, 82, 82}

{78, 81, 82}

{81}

The last value is the median as it is in the very middle. So the median is 81.

-----------

Check out the attached image below to see the various items crossed off. Note the color coding to see how the terms pair up when crossed off. Only the 81 isn't crossed off showing it is the middle most value.

Answer:

I guess that "Ura nok seblu" means that all rocks sink in water.

Step-by-step explanation:

A conjecture is an idea, opinion, theory or hypothesis, that is based on partial or incomplete information or evidence. Conjectures are generally speculations since there is not enough proof or evidence to support them.  

Even though Stony's theory didn't have a lot of evidence to support it, he was almost right. Most rocks sink in water, I guess that the only rock that doesn't is pumice. I might be wrong, but I don't know of any other rock that floats.

Answer:

J'(7,-4), K'(-7,-1), L'(-2,2)

Step-by-step explanation:

reflection over x-axis: (x,y) --> (x,-y)

reflection over y-axis: (x,y) --> (-x,-y)

Because the triangle is reflected x-axis and then y-axis,

all points would be (x,y) --> (-x,-y)

Answer:

54.4%

Step-by-step explanation:

43/79 = x/100

79*x = 43*100

79x = 4300

x = 4300/79

x = 54.4
