Answer:

q=26.92 p=31.13

Step-by-step explanation:

p^{2} +16q=1400\\\\q=\frac{1400-p^{2} }{16} ;\\\\700-p^{2} +10q=0\\\\q=\frac{p^{2}-700 }{10} ;\\\\

q=q\\\\\frac{1400-p^{2} }{16} =\frac{p^{2}-700 }{10} \\\\10(1400-p^{2})=16(p^{2}-700)\\\\14000-10p^{2}=16p^{2}-11200\\\\14000+11200=16p^{2}+10p^{2}\\\\25200=26p^{2}\\\\p^{2}=\frac{25200}{26} \\\\p=+\sqrt{\frac{25200}{26}} \\\\p=31.13

replace p in any equation and

q=\frac{1400-p^{2} }{16} \\\\q=\frac{1400-(31.13)^{2} }{16}\\\\q=26.92

A cube has side length a.The side lengths are decreased to 30% of their original size.Write an expression in simplest form for t
jeka94

Answer:

Volume V = 0.027a^3

Step-by-step explanation:

Let a represent the length of the side length of the cube.

a.The side lengths are decreased to 30% of their original size;

l = 30% of a

l = 0.3a .....1

The volume of a cube can be expressed as;

V = l × l × l

V = l^3 .......2

Where;

l = side length

Substituting the value of l into equation 2;

V = l^3 = (0.3a)^3

V = 0.027a^3

Volume V = 0.027a^3

What is the greatest perfect square that is a factor of 396? Explain
DedPeter [7]
<span>To find the greatest perfect square  that is a factor of 396, first we check what are the factors of 396
Factors of 396 are: 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396
Now we check which is the greatest perfect square in these. 
396, 198, 132, 99, 66,44 are not perfect square,
so 36 is the largest perfect square from the factors of 396, 6 x 6 = 6</span>² = 36

Help pls!!!!!!!!!!!!!!!!
Anastaziya [24]

ANSWER.


The correct answer is Option A


EXPLANATION.


The real number

\sqrt{35}=5.916079783


to 9 decimal places.


You can see that the decimals are not repeating, neither will they terminate.



Therefore the real number \sqrt{35} is irrational because, the decimal does not terminate or repeat


Also note that,


\sqrt{35}=\sqrt{5} \times \sqrt{7} .


That is,

\sqrt{35} is a product of two irrational numbers, which still gives an irrational number.
