can any of you guys help out by showing work on how this is the answer
Answer:
Step-by-step explanation:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100000000
100000000 x 6.85 = 685,000,000
Answer:
scientific notation. I did this a few moths ago.
Step-by-step explanation:
since it is 10^8 you're going to move your decimal as far the right as you can which then changes it to 685. x 10^6. After that you add 6 zeros (from the 10^6) and change it from a decimal to a comma to get 658,000,000... i hope this helps

What is the difference between Standard Notation and Scientific Notation?
Answer:
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. Standard notation is the normal way of writing numbers.
Answer:
Scientific notation: c * 10^n where 1 <= c < 10
Now standard notation is basically multiplying c * 10^n out
For example:
Scientific notation: 4.5 * 10^4
Would be written as 45000 in standard notation (either multiply by 4.5 * 10^4 or just simply move the decimal in 4.5 four places to the right)
For example:
Scientific notation: 0.6 * 10^-3
Would be written as 0.0006 in standard notation (either multiply by 4.5 * 10^-3 or just simply move the decimal in 0.6 three places to the left)
PLEASE HELP!!!!! ASAP
Answer:
y = -x + 30
Step-by-step explanation:
You will want to put the equation in the form y = mx + b where m is the slope and b is the y-intercept (an example is y = 2x - 1).
First, to find the slope you want to find how much x goes up by when y goes up by 1. You know from the table that when y goes up by 5, x goes up by -5 (using the points (10, 20) and (5, 25))
Then, you can divide each value by 5, so it would be when y goes up by 1, x goes up by -1. That means the slope is -1.
So far, the equation is y = -x + b. To find b, you can plug in one of the points you have and solve for b. For example, substitute in x = 10 and y = 20, so:
20 = -10 + b
add 10 to both sides
30 = b
So you know the equation is y = -x + 30
Please let me know if any parts of these explanation are confusing, I definitely think this concept can be confusing at time. Good luck with your work! :)
Answer:
To create an equation, you need to find the slope first. The slope formula is [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]. Let's use two random coordinates: (10,20) and (5,25). Plug in these digits into the formula to get [tex]\frac{25-20}{5-10}[/tex]. Simplify to get [tex]\frac{5}{-5}[/tex] or -1. The equation would look like y=-x+b. Now we need to find b. Again, let's use a random coordinate: (10,20). Plug in the digits into the variables to get 20=-10+b. Add 10 on both sides to get 30=b. So, the equation would be y=-x+30.

Construct an isosceles right-angled triangle ∆PQR where ∠
Answer:
Please find attached the required triangle drawn with Microsoft Visio
Step-by-step explanation:
The isosceles triangle ΔPQR we are to construct has the following parameters;
∠PQR = 90°
Length of side hypotenuse PR = 4 cm
Therefore, given that the triangle is right triangle is an isosceles triangle the length of each of the side legs are equal
Therefore, we have;
Length of PQ = Length of QR
The length of the legs , [tex]\overline {PQ}[/tex] and [tex]\overline {QR}[/tex], are given by Pythagoras's theorem as follows;
[tex]\overline {PR}[/tex] = √([tex]\overline {PQ}[/tex]² + [tex]\overline {QR}[/tex]²) = √([tex]\overline {PQ}[/tex]² + [tex]\overline {PQ}[/tex]²) = [tex]\overline {PQ}[/tex]·√2
∴ [tex]\overline {PQ}[/tex] = 4 cm/(√2) = 2·√2 cm = [tex]\overline {QR}[/tex]
The required triangle drawn with Microsoft Visio is attached
1. There are 16 boys and 18 girls in a Grade 6 math class. Write the ratio of girls to boys in words as simply as possible.
2. The ratio of blue marbles to yellow marbles is 5:1. For every yellow marble, there are ___ blue marbles.
Answer:
1.)8 boys yo 9 girls
2.)5
Step-by-step explanation:
1)divide by 2
2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble
The ratio of boys to girls in the Grade 6 math class is =
8 : 9.
For every yellow marble, there are five blue marbles.
To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.
To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.
Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.
The 5:1 ratio of blue to yellow marbles means for every yellow marble, there are five blue marbles.

What is the surface area of a sphere that
has a diameter of 12 inches?
Answer: The surface area is 452.39in²
Step-by-step explanation:
Formula
A=4πr²
d= 2 r
Solving for A
A=πd²=π·12²≈452.38934in²
The surface area of a sphere that has a diameter of 12 inches is 452.39 in².
To solve the question, we need to know what the surface area of a sphere is.
What is the surface area of a sphere?The surface area of a sphere is given by A = 4πr² where
r = radius of sphere = d/2 where d = diameter of sphere.Given that d = 12 inches, r = d/2 = 12 in/2 = 6 in
Substituting the value of r into A, we have
A = 4πr²
A = 4π × (6 in)²
A = 4π × 36 in²
A = 144π in²
A = 452.39 in²
So, the surface area of a sphere that has a diameter of 12 inches is 452.39 in².

using the slope equation y^2 - y^1/ x^2 - x^1, where
-3=x^1
3=x^2
0= y^2 and y^1 because they have the same value
0 - 0/3 - -3
0/6
Therefore, the slope is equal to 0/6
