Answer:

6.829 \cdot 10^3

Step-by-step explanation:

6829 km expressed in scientific notation

To represent a number in scientific notation we move the decimal point after the first number.

We need to get decimal point after 6

All whole number have a decimal point at the end

6829.

Move the decimal point 3 units to the left

when we move decimal point 3 units to the left we multiply by 10^3

6.829 \cdot 10^3 is in scientific notation

Move the decimal until there is 1 whole number

6.829

3 units

so 6.829 * 10^3

A crater shaped like a cone has a height of 24 yd and a diameter of 72 yd.
mezya [45]
The formula for the volume of a cone is (1/3)*area of the base * height. The base is a circle, whose area is pi times radius^2. Here this is pi * (r^2) = 3.14*(72 / 2 yd)^2 = 4069.44 yd^2. And so the volume is (1/3) * 4069.44 yd^2 * 24yd = 32,555.52 yd^3. I recommend that you find the most common formulas of the geometrical figures and make a flashcard that you can use at any moment.

Amuseumcharges forgeneraladmission and exhibitions. Admission and 3 exhibitionscosts $45. Admission and 5 exhibitionscosts $65.
leonid [27]

Answer:

The price of the admission is 15.

Step-by-step explanation:

From the information given, you can write the following equations:

a+3e=45 (1)

a+5e=65 (2), where:

a is the admission cost

e is the exhibition cost

First, you can solve for a in (1):

a=45-3e (3)

Second, you can replace (3) in (2):

45-3e+5e=65

45+2e=65

2e=65-45

2e=20

e=20/2

e=10

Finally, you can replace the value of e in (3):

a=45-3e

a=45-3(10)

a=45-30

a=15

According to this, the price of the admission is 15.

The equation of the line in this graph is<br>y= ____ x+____ .<br>​
Alexxx [7]
The equation of the line in this graph is y = 3/2x + 3.

Explanation:

In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.

Solve the system of equations and choose the correct ordered pair. 
Ksivusya [100]
L.H.S is already equal, so just subtract 1st equation from second, 
2y = 12
y = 6

Now, substitute it in 1st equation, 
2(6) = 4x + 8
4x = 12 - 8
x = 4/4
x = 1

In short, Your Answer would be Option C) (1, 6)

Hope this helps!
