Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.

A large clock on a county courthouse has a circumference of about 25 feet. The minute hand extends from the center of the clock to the edge of the clock. How long is the minute hand?
Answer:
Minute hand = 3.98 feet
Step-by-step explanation:
Circumference of a circle can be calculated by
C = 2 x pi x radius
The minute hand extends from center to the edge means that minute hand is the radius and that is required.
putting values in above equation
C = 25 and pi = 3.14
25 = 2 x 3.14 x radius
radius = 25 / 6.28
Radius = 3.98 feet

Kaitlyn opens an account with an initial deposit of $7,250. The account earns 10% interest compounded annually. What is the amount of interest earned after 18 months if no additional money is deposited or withdrawn?
Answer:
the interest earned amount is $1,114.251
Step-by-step explanation:
The computation of the interest earned is shown below:
But before that the future value is
= Present value × (1 + rate of interest)^number of years
= $7,250 × (1 + 0.10)^1.5
= $7,250 × 1.10^1.5
= $8,634.251
Now the interets earned is
= $8,634.251 - $7,250
= $1,114.251
Hence, the interest earned amount is $1,114.251

Given the area of a rectangle is 2x2 - 5x - 12, what is the width if the length is x – 4?
Answer:
2x + 3
Step-by-step explanation:
So, the equation here is:
[tex]\frac{2x^2 - 5x - 12}{x - 4}[/tex]
And so, using this we can set up our synthetic equation using the dividends as the coefficients of the equation, which are 2, -5, and -12; and the divisor 4, which derives from -4.
It's a bit hard to create a table here, so I'll just write out the values and hope you piece it together.
4 | 2 -5 -12
| 2 8 12
2 3 0
Thus, we are given our coefficients for our desired equation.
2x + 3
And we can ascertain this to be the answer by working the converse.
(2x + 3)(x - 4)
2x² - 5x - 12

Factor the following trinomial:
Answer:
D
Step-by-step explanation:
Given
n² - n - 42
Consider the factors of the constant term (- 42) which sum to give the coefficient of the n- term (- 1)
The factors are - 7 and + 6 , since
- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then
n² - n - 42 = (n - 7)(n + 6) ← in factored form
Solution :-
Given,
n^2 - n - 42We need to factorise it.
So let's start !!
Two factors are -7 and 6.
Therefore,
n^2 - 7n + 6n - 42 n (n - 7) + 6 (n - 7) (n - 7) (n + 6)3

Answer:
7/11 if its not that then its 64% Hope this helps!
Step-by-step explanation:
Since there are 11 letters in the word mathematics, and 7 consonants, you have the fraction 7/11. however, if it's required as a percentage, We know that
7/11
is the same as
7÷11
Then using
Long Division for 7 divided by 11
gives us
0.636
Converting our number to a percentage:
0.636×100
is 64% rounded to the nearest 10. Rounding to the nearest hundredth, you'd get 63.64%
