Answer:

Step-by-step explanation:

The surface area of a sphere (which the earth is considered to be) = 4 pi r^2

pi = 3.14

r = 6340

Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.

You should either round this to 505,000,000 or express a value in scientific notation.

Answer:

Let's simplify step-by-step.

3x2+9x+6−(8x2+3x−10)+(2x+4)(3x−7)

Distribute:

=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28

Combine Like Terms:

=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28

=(3x2+−8x2+6x2)+(9x+−3x+−14x+12x)+(6+10+−28)

Answer:

Step-by-step explanation:

the product of 9 and t is:  9•t

the sum of t and 2 is:   t+2

increasing means adding, so:

the product of 9 and t increased by the sum of t and 2 would be:

9t + (t + 2) = 9t + t + 2  = 10t +2

Answer:

3⅞ is the answer to the question.

Step-by-step explanation:

The ten lightest tomatoes are in ¼, ⅜, ½, ⅝ and ⅞.

In ¼, there are 3 tomatoes, so that would be “¼×3=¾”.

In ⅜, there are 2 tomatoes, so that would be “⅜×2=¾”.

In ½, there are 3 tomatoes, so it would be “½×3=3/2”.

In ⅝, there is 1 tomato, so it would be “⅝×1=⅝”.

In ⅞, there is 1 tomato, so that would be “⅞×1=⅞”.

Now add all together:

¾ + ¾ + 3/2 + ⅝ + ⅞

= 5+5+7+6+8/8

= 31/8

= 3⅞

Answer:

Step-by-step explanation:

If there are 27 total cards to be played in a cards of game and each player collects 4carda, the total number of people in the game = Total number of card/amount of card received per person.

total number of people in the game = 27/4 = 6 Remainder 3

The amout of card remaining will be 27-6(4)

= 27-24

= 3

The amount of card remaining is 3 cards

0.00419 = 4.19 * 10^-3.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by

Expression; [tex]\rm \dfrac{4+2i}{8-3i}[/tex]

A complex conjugate is formed by changing the sign between two terms in a complex number i.e. a+ ib has conjugate a-ib and a- ib has conjugate like a+ ib.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

[tex]=\rm \dfrac{4+2i}{8-3i}\\\\= \rm \dfrac{4+2i}{8-3i}\times \dfrac{8+3i}{8+3i}\\\\= \dfrac{(4+2i) \times (8+3i)}{(8)^2-(-3i)^2}\\\\= \dfrac{32+12i+16i+6i^2}{64+9}\\\\=\dfrac{32+28i+6i^2}{73}[/tex]

Hence, The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

Answer:

b=7

Step-by-step explanation:

Plug 3 into a since a=3.

2(3)+b=13

Then solve for 2(3)

6+b=13

Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)

b=13-6

b=7

Answer:

x=6

Step-by-step explanation:

The equation we start with is

4x-6+4=2x+10

First combine like terms

4x-2=2x+10

Next subtract 2x from both sides so that the variable is only on the left side

2x-2=10

Now add 2 to both sides to isolate your variable

2x=12

Finally divide both sides by 2 to find your answer

x=6
