Answer:

The surface area of the star is approximately 1.004 times larger than the earth's surface area

Step-by-step explanation:

To find the number of times b which the area of the star is larger than that of the earth, we will divide the area of the area of the star by the area of the earth.

Area of surface of star = 1015 square miles

Area of surface of the earth = 1011 square miles

∴ (Area of star) ÷ (Area of the earth)

= 1015 ÷ 1011 = 1.00395 times

Therefore the surface area of the star is approximately 1.004 times larger than the earth's surface area

Answer:

students 150

adult 550

Step-by-step explanation:

x + y = 700

5x + 2y = 3050

x = 700 - y

5(700 - y) + 2y = 3050

3500 - 5y + 2y = 3050

-3y + 3500 = 3050

-3y = 3050 - 3500

-3y = -450

y = -450 / -3

y = 150

x = 700 - y

x = 700 - 150

x = 550

Answer:

B

Step-by-step explanation:

A constant variation graph has the following format:

[tex]y=kx[/tex]

Where k is the constant of proportionality.

Let's pick a point from the graph, say, (1,5).

Substitute 1 for x and 5 for y:

[tex]5=1(k)[/tex]

Simplify:

[tex]5=k[/tex]

Therefore, the constant of proportionality is 5.

Answer:

0.4  since the number is non terminating and non repeating therefore it is irrational number.

-78  A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero

15  The number 15 is a rational number. It is an integer and all integers are rational numbers.

0 Yes zero is a rational number. Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer.

Answer:

Step-by-step explanation:

the answer is 25 not 5

The numeric value of x will be 25 for the given line segment.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the line segment AC

AC = AB + BC

Given,

AB = 2x + 10, BC = x, and AC = 5x,

So,

5x = 2x + 10 + x

5x = 3x + 10

2x = 10

x = 5

So,

AC = 5x

AC = 5(5) = 25 units.

Hence, The numeric value of x will be 25 for the given line segment.

Answer:

1/ 4

Step-by-step explanation:

The question can also be written as [tex]\frac{1}{3} /\frac{4}{3}[/tex] .

Because it's division of fractions, you can multiply to find the answer by making 4/3 into 3/4. So

1/ 3 times 3/4 = 3/12 = 1/4

Answer:

if you're trying to find the quotient then the answer is: 4/9

if you're trying to add then the answer is: 5/3

if you're trying to divide then the answer is: 4/9

if you're trying to multiply then the answer is: 4/9

if you're trying to simplify then the answer is: 4/9

Step-by-step explanation:

Answer: C=250S+4500

C=250(17) + 4500    

C=4250+4500

C=8750

Step-by-step explanation:

As an equation, 250 would be the slope because it is multiplying by the ton and 4500 is the y intercept. If you substitute in 17 for S, then multiply 17 by 250, you get 4250 then add the 4500 and you get 8750 so if S=17, C=8750

The cost of transporting 17 tons of sugar is $8750.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

The given information can be related as,

C = 250S + 4500.

Now, when tons of sugar is 17 we'll simply replace S with 17.

∴ C = 250(17) + 4500.

C = 4250 + 4500.

C = 8750.

Answer:

7 meters

Step-by-step explanation:

Now write an equation that represents the situation. You want to find the change in the dolphin's depth, so subtract its beginning depth from its final depth.

The change in the dolphin's depth is negative 7 meters.

Subtraction of two or more numbers or algebraic expressions is the method of taking away a certain value from a number. This operation is also called difference of numbers.

Subtraction is one of the basic operations in mathematics along with division, multiplication and addition.

Initial depth that Dolphin was swimming = 28 meters

Then the Dolphin changed it's depth to avoid predator.

Final depth that Dolphin was swimming = 21 meters

Change in depth = Final depth - Initial depth

                            = 21 - 28

                            = -7 meters

This implies that depth of the Dolphin decreases with -7 meters.

Hence the change in the Dolphin's depth is -7 meters if the initial depth was 28 meters and final depth was 21 meters.

Answer:

3.343481472 x 10^4

Step-by-step explanation:

11.6 a = 3.25 *

6.18 * = 2.5 #

Take the first equation and solve for *

11.6 a = 3.25 *

Divide each side by 3.25

11.6 a/3.25 = *

3.569230769 a = *

Substitute this into the second equation for *

6.18  (3.569230769 a)  = 2.5 #

22.05784615 a =  2.5 #

Solve for a

Divide by 22.05784615

a = 2.5 # /  22.05784615

a = .113338355

We have 2.95 x 10 ^5 a
