Complete Question

Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)

Answer:

510,000,000 million km²

Step-by-step explanation:

Let us represent the total surface area of the earth as = x

We are told in the question that:

Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface.

70.8% = 0.708

Hence,

0.708 × x = 3.61 × 10⁸

x = 3.61 × 10⁸/0.708

x = 361000000/0.708

x = 509,887,005.65km²

Therefore, the total surface are the earth approximately to the nearest million = 510,000,000 million km²

Answer:

C -2 < x ≤ 1

Step-by-step explanation:

-5< 4x +3 ≤ 7

Subtract 3 from all sides

-5-3< 4x +3-3 ≤ 7-3

-8< 4x  ≤ 4

Divide all sides by 4

-8/4< 4x/4  ≤ 4/4

-2 < x ≤ 1

Answer:

164

Step-by-step explanation:

7x + 24 = 6x - 20 + 64

7x - 6x = 64 - 20-24

x = 64 - 44

x = 20

KM = 7x + 24 = 7*20 + 24 = 140 + 24

KM = 164

Answer:

27.38

Step-by-step explanation:

This is the answer because:

1) Standard form means to write the full number

2) First we have to multiply because we have to use order of operations

3) So do 2 x 10 which is 20

4) Then, do 7 x 1 which is 7

5) Next, do 3 x 0.1 which is 0.3

6) Finally, do 8 x 0.01

The new equation is:

20 + 7 + 0.3 + 0.08

This expression equals to 27.38

Therefore, the answer is 27.38

Answer:

C.   100 ≤ 20x 1000

Step-by-step explanation:

area of a rectangle is L x W

where W = 5,  L = 4x

area 100 ≤ A ≤ 1000

A = 5 (4x)

= 20x

in which inequality 100 ≤ 20x 1000

Length of the base edge (a) = 5 cm

Height of the pentagonal prism (h) = 10 cm

The Lateral Surface Area of the Pentagonal Prism.

Lateral Surface Area of a Pentagonal Prism = 5ah

Lateral Surface Area = 5 (5) (10)

Lateral Surface Area = 5 (50)

Lateral Surface Area = 250 sq.cm

Answer:

Step-by-step explanation:

if x = y, and y = z, you can write that as x = y = z, which means that x = z

Answer: 0

Step-by-step explanation:

No matter how you go at it, x is inevtably going to equal 0. To get x by itself, you have to subtract 3 from the right and left side, which leaves 0=x-5x. That leaves you with -4x=0, and when divided, that equals zero.

Answer:

x = 0

Step-by-step explanation:

Given

3 = x + 3 - 5x , that is

3 = - 4x + 3 ( subtract 3 from both sides )

0 = - 4x , thus

x = 0

Answer:

Step-by-step explanation:

[tex]\frac{2}{5} x + 15 = x - 6[/tex]

First multiply through by 5 to eliminate the fraction

That's

[tex]5 \times \frac{2}{5} x + 15(5) = 5x - 30 \\ 2x + 75 = 5x - 30[/tex]

Next using the subtraction property subtract 5x from both sides

That's

[tex]2x - 5x + 75 = 5x - 5x - 30 \\ - 3x + 75 = - 30[/tex]

Next subtract 75 from both sides

[tex] - 3x + 75 - 75 = - 30 - 75 \\ - 3x = - 105[/tex]

Divide both sides by - 3

[tex] \frac{ - 3x}{ - 3} = \frac{ - 105}{ - 3} [/tex]

We have the final answer as

Answer:

The answer is 65,-4

Step-by-step explanation:

x coordinates is 65 while the Y coordinates is -4

The answer is x=70 and y= -4 so (70, - 4)

Answer:

Step-by-step explanation:

Given the equation solved by Morgan, Dakota and Taylor expressed as 7x+5x+1=73, to get the value of x, the valid steps are as shown;

7x+5x+1=73

take the sum of 7x and 5x

12x+ 1 = 73

subtract 1 from both sides

12x+1-1 = 73-1

12x = 72

Divide both sides by 12

12x/12 = 72/12

x = 6

Based on the calculation above, the students with invalid first step is Dakota.

Dakota added 5x with 1 to get 6x which is an invalid step because 1 is not attached to a variable x. A function cannot be added to a constant hence making his first step invalid.

Answer:

As you can see, Taylor failed to add 1 to her equation. This ruins the whole first step. She also used 72 instead of 73 for the answer. Taylor is incorrect.

The answer is $25.5!
