The length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.
According to the question, we are required to determine the length of line JL.
However, the coordinates of the end points of line JL are given as;
Point J; (8,10)Point L; (20,5).The length of line JL is given by Pythagoras theorem as;
JL = √(20-8)² + (5-10)²JL = √ 12² + (-5)²JL = √ 144 + 25JL = √169JL = 13.
Therefore, the length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.

How much larger is 6 x 10^5 compared to
2 x 10^3?Explain how you know.
Answer:
6 x 10^5 is 300 times greater than 2 x 10^3.
Step-by-step explanation:
Use division to compare.
(6 × 10^5)/(2 × 10^3) = 6/2 × 10^5/10^3 = 3 × 10^2 = 3 × 100 = 300
6 x 10^5 is 300 times greater than 2 x 10^3.
There is 6 × 10⁵ is 300 times greater than 2 × 10³.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The exponents are given in the question, as follows:
6 × 10⁵ and 2 × 10³
The exponents in scientific notation as a shorthand for the number of zeroes in the number.
We use division to compare.
( 6 × 10⁵)/(2 × 10³)
= 6/2 × 10⁵/10³
= 3 × 10²
= 3 × 100
= 300
This means 6 × 10⁵ is 300 times greater than 2 × 10³

Volume? Correct answers please
Answer:
V = 1385.44
Step-by-step explanation:
The equation for volume is V = π r 2 h! Where V = volume, r = radius (half the diameter), and h = height. Now lets substitute what we know into this equation!
Since we are giving the diameter (14) we must divide by 2 to find the radius.
14 ÷ 2 = 7
Radius = 7
Height = 9
V = ?
Time to plug these values in!
V = π [tex]7^{2}[/tex] (9)
We have to distribute pi to 7 square that term and then multiply the value by 9.
V = 1385.44

which of the expressions have a value of 2?
Answer:
The answers are B and E
Step-by-step explanation:
The square root of 4 is 2.
The cube root of 8 is 2.
A is wrong because its value is 4.
C is wrong because its value is 4.
D is wrong because the square root of 8 isn't whole.
Answer:
E. √4
B. ³√8
Step-by-step explanation:
You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)
You can also determine that B is correct by doing 2 to the power of 3.
2³ = 8, so you know that B is correct too.

Last year, a lighting supplier called Bright Idea shipped a total of 37,220 lamps to its distributors. This year, the supplier shipped 29,776 lamps. What is the percent of decrease in the number of lamps shipped annually?
Answer:
25%
Step-by-step explanation:
Given data
Last years shipment= 37220 lamps
These years shipment= 29776 lamps
% Decrease= Initial-Final/Initial*100
% Decrease= 37220-29776/29776*100
% Decrease= 7444/29776*100
% Decrease= 0.25*100
% Decrease= 25%
Hence the decrease is 25%
