\bf \textit{total surface area of a cone}\\\\
S=\pi r\sqrt{h^2+r^2}+\pi r^2\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=8\\
h=14
\end{cases}
\\\\\\
S=\pi (8)\sqrt{14^2+8^2}+\pi (8)^2\implies S=8\pi \sqrt{260}+64\pi 
\\\\\\
S\approx 405.25+201.06\implies S\approx 606.31

Find two rational numbers between 5/6 and 83/ 100 . Explain how you know (without using decimals)
kolbaska11 [484]

Answer:

998/1200 and 997/1200

Step-by-step explanation:

It’s hard to compare 5/6 and 83/100 in their current states. Let’s find a common denominator. Take 600. We know that this will work because both 6 and 100 go into it. Multiplying 5 by 100 and 83 by 6 to find the common denominator, we can compare them at 498/600 and 500/600. However, there is only one number (499/600) between them. Thus, we will multiply each number by 2/2, which is 1. Our numbers are then 996/1200 and 1000/1200. Two numbers between them are then 997/1200 and 998/1200

Which expression represents 12x³-6x²+2x ÷2x in simplest form?​
Elden [556K]

Answer:

x^2 (12 x - 5)

Step-by-step explanation:

Simplify the following:

12 x^3 + (2 x x)/2 - 6 x^2

(2 x x)/2 = 2/2×x x = x x:

12 x^3 + x x - 6 x^2

x x = x^2:

12 x^3 + x^2 - 6 x^2

x^2 - 6 x^2 = -5 x^2:

12 x^3 + -5 x^2

Factor x^2 out of 12 x^3 - 5 x^2:

Answer: x^2 (12 x - 5)

Temka [501]
K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
The answer would be: 2.5

KATRIN_1 [288]

Answer:  Amount of sales s = $6240 is the salary at ABC company is greater than at XYZ company.

Step-by-step explanation:

Since we have given that

Annual salary of ABC company = $45000

Annual salary of XYZ company = $38000

Rate of commission = 2%

Amount of salary after commission at XYZ company would be

\dfrac{100+2}{100}\times 38000\\\\=\dfrac{102}{100}\times 38000\\\\=1.02\times 38000\\\\=38760

So, Difference between is given by

45000-38760\\\\=\$6240

Hence, Amount of sales s = $6240 is the salary at ABC company is greater than at XYZ company.
