Answer:

Step-by-step explanation:
<em>Standard form</em>, also called <em>scientific notation</em>, is a more compact way of writing very big or very small numbers. All numbers in scientific notation have the form

where m is a number between 1 and 10, and b is an integer that represents how we've shifted the decimal point from the original number. For example, the number 23,000 in standard form would be written as 2.3 × 10⁴, since we have to shift the decimal point 4 places to the right to get back our original number.
We can turn 5,976,000,000,000,000,000,000,000 into a number between 1 and 10 by shifting the decimal 24 places to the left, giving us 5.976. We'll save that 24 as the exponent for our 10, giving us the final form

Yes (2,5) is a solution to the system of equation
2+2 (5)=12
2+10=12
12=12
2(2)+2(5)=14
4+10=14
14=14
Answer:
Properties are assessed for tax pruporses taking a fraction of property value and applying the tax rate.
In this case say at 11 of its value (I suposse that it means 1/11)
So the value assesed is

Applying the tax

So the amount levied is $191.25 in the case that the property is assessed at 1/11 of its value. In other case you can follow the same procedure using the respective fraction.
Answer:
B
Step-by-step explanation:
<em>Let
be the radius of one sphere.</em>
- Volume of sphere is

Since radius is r, the height of the cylinder will be 
Also, the cylinder has the same radius as the sphere: 
- Volume of Cylinder is

Plugging in the values we get: 
<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:

The ratio is 1:3
Answer choice B is right.
Answer:
(- 2, 2 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 2x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 2x - 2 ( add 2x to both sides )
3x + 4 = - 2 ( subtract 4 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Substitute x = - 2 into either of the 2 equations abd evaluate for y
Substituting into (1)
y = - 2 + 4 = 2
solution is (- 2, 2 )
