Which law would you use to simplify the expression x49

Answer:

It mus be 70 because you half 140 hence its called 'half life'

Answer:

Length SD is greater than length DM.

Step-by-step explanation:

We know that the measure of the opposite angle and a side are related, so by determining which angle is bigger, we can discover which side is longer.

Angle SUD is greater than angle MUD. Angle SUD is the opposite angle to SD, and angle MUD is the opposite angle to DM. Therefore, SD is greater than DM.

step by step

Answer/Step-by-step explanation  (ac > b² or b² < ac. )

A/c to question, we have to show:-

b² >ac in A.P ........ (1)

b² = ac in G.P .....(2)

b² < ac in H.P. ..... (3)

b = a+c/2 (A.P)

b = √ac ( G.P)

b = 2ac/a+c (H.P)

In A.P :

b² > ac = b² - ac

= (a+c/2)² - ac

= (a²+2ac+c²/4) - ac  = a² + 2ac + c² - 4ac / 4

= a² - 2ac + c² / 4  = ( a - c ) ² / 4 > 0  Hence, b²>ac

In G.P:-

b = √ac

Hence, b² = ac

In H.P :-  b² < ac = ac > b²  = ac - b²  = ac - ( 2ac / a+c)

= ac(a+c) - 2ac / a+c

= a²c + ac² - 2ac / a+c

= ac(2ac - 2) / a+c > 0

Hence, ac > b² or b² < ac.

22.74 i think

Step-by-step explanation: Add 22.75 to 10.50 then subtract that number to 55.99

Answer:

22.74

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) 97 + x = 64 + 27          {Exterior angle property}

    97 + x = 91

            x = 91 - 97

          x = -6

2) 4x + 17 + 80 + x + 23 = 180   {Angle sum property of triangle}

 4x + x + 17 +80 + 23 = 180

                 5x + 140   = 180

                             5x = 180 - 140

                              5x = 40

                                 x = 40/5

                                x = 8

Answer:

  D.  -16/5

Step-by-step explanation:

-3.2 = -32/10 = -16/5 . . . . matches choice D

_____

More detail

Any finite decimal can be converted to a fraction by considering the place value of the digits.

  3.2 = 3×1 + 2×(1/10)

  = 3 + 2/10 = (30 +2)/10 = 32/10

Then common factors can be cancelled from numerator and denominator.

  32/10 = (2·16)/(2·5) = 16/5

The negative sign can be applied as required.

  -3.2 = -(3.2) = -(16/5) = -16/5

Answer:

[tex]2(x+4)[/tex] is a product

Step-by-step explanation:

Given

[tex]2(x+4)[/tex]

Required

Select a true statement

The expression can be rewritten as:

[tex]2 * (x+4)[/tex]

When we split the expression to 2, we have:

[tex]Term\ 1 = 2[/tex]

[tex]Term\ 1 = x + 4[/tex]

The * between both terms implies that the expression is a product.

And it has 2 terms.

Answer:

x=11°

Step-by-step explanation:

If we stretch line segment B(and use the theorem of same side interior angles) we see that 2x+33°=5x

5x-2x=3x

33°=3x

x=11°

Answer:

x = 11

Step-by-step explanation:

55-22=33

all these numbers are multiples of 11

Answer:

48

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

81×61=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

8×61×1=481

Since 48 divided by 1 equals 48 then,

481=48

Therefore:

81÷16=48

Answer:

58 yards^2

Step-by-step explanation:

You want to break this irregular shape into simple shapes. You can make a rectangle with the sides of 4 and 6 yards, whose are is 24 yards^2.

Then you can do the rectangle on the opposite side, whose sides are 4 and 6 yards, whose are is 24 yards^2 again.

Then the final rectangle has the sides of 5 and   2 yards, whose area is 10 yards^2.

If you add it all up, you will get 58 yards^2.

Answer:

[tex]h = \frac{S - 2B}{P}[/tex]

Step-by-step explanation:

Given

[tex]S=Ph + 2B[/tex]

Required

Select an equivalent expression (see attachment)

[tex]S=Ph + 2B[/tex]

Subtract 2B from both sides

[tex]S - 2B = Ph + 2B - 2B[/tex]

[tex]S - 2B = Ph[/tex]

Divide both sides by P

[tex]\frac{S - 2B}{P} = \frac{Ph}{P}[/tex]

[tex]\frac{S - 2B}{P} = h[/tex]

Reorder

[tex]h = \frac{S - 2B}{P}[/tex] --- Option (b)

The equivalent equation is "[tex]P=\frac{S-2B}{P}[/tex]"

[tex]\to S= Ph+2B[/tex]

solving the given equation:

[tex]\to S= Ph+2B\\\\\to S-2B= Ph\\\\\to \frac{S-2B}{P}=P\\\\\to P=\frac{S-2B}{P}\\\\[/tex]

Therefore, the final answer of the given equation is "[tex]P=\frac{S-2B}{P}[/tex]".

Answer:

Step-by-step explanation:

(a^2 - 5ab) - (7 - 3ab) + (2ab - a^2) = -7

a^2 - 5ab -7 +3ab + 2ab -a^2 = -7 [combine like terms]

a^2 - a^2 = 0

-5ab + 3ab + 2ab = 0

-7 = -7

Answer:

Step-by-step explanation:

you can bring -(7-3ab) to the other side of the equation . then you will have this : (a^2 - 5ab) + (2ab - a^2) = -7 + (7 - 3ab)

now look at this part : -7 + (7 - 3ab) (because adding is a associative procedure) you can get rid of -7 and 7 . then you will have only -3ab

so now this would look like this :  (a^2 - 5ab) + (2ab - a^2) = -3ab

now take a look at the left of the equation : just like the last part we can simplify a^2 and - a^2 . and -5ab + 2ab would result in -3ab

because if you subtract -5ab from a^2 and subtract a^2 from 2ab ... then add then to each other would give you the same result

at the end you will have -3ab = -3ab which is a true conclusion.

Answer:

BBBBBBBBBBBBBBBBBBBBBBBB

Answer:

2

Step-by-step explanation:

To find the scale factor of a dilation, we first find two corresponding sides. For example, the leftmost side of the black shape corresponds with the leftmost side of the blue shape. The side on the black shape measures 2 units while the side on the blue shape measures 4 units.

Now, we divide the length of the side taken from the figure by the length of the side taken from the original shape.

4/2=2

Therefore, the scale factor of the dilation is 2.
