Prove the quotient of any two rational numbers is a rational number

1 answer:

4 0

That is not possible, a quotient or any equation for that fact can only be rational when it lacks repeating {x} values. Take for instance this 2x11x2^2+(1+10)=

In the equation the {x} values would be most likely described as {2}. Since 2 was the quotient that was being repeating hence that equation not being rational. Hope this helps!

Answer:

36.6 cm

Step-by-step explanation:

We have the rectangle upright and the rectangle on its side.

Counting the sides starting from the lower left vertex and going clockwise.

7 + 4.3 + (7 - 4.3) + 7 + 4.3 + 7 + 4.3

= 7 + 4.3 + 2.7 + 7 + 4.3 + 7 + 4.3

= 36.6 cm

Solve: y=-3x+5 5x-4y=-3

Dafna1 [17]

Use y=-3x+5 on this equation 5x-4y=-3

5x-4(-3x+5) = -3
5x+12x-20 = -3
17x=17
x=1

y=-3x+5
for x=1;
y=-3+5
y=2

Leto [7]

Answer:

yes

Step-by-step explanation:

using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $\frac{1}{a^{(n-m)} }$ , then

$\frac{9^2}{9^{7} }$ = $\frac{1}{9^{(7-2)} }$ = $\frac{1}{9^{5} }$

Kimmy saving accounts has a balance of $76.23 in June by September her balance is 5 time as much as her June balance between Sep

hammer [34]

Answer:

Kimmy balance in December will be $545.21.

Step-by-step explanation:

Given:

Balance in account in June = $76.23

Now Given, by September her balance is 5 time as much as her June

It means that Balance in account till September is 5 times Balance in account in June.

framing in equation form we get;

Balance in account till September = $5\times \$76.23 = \$381.15$

Also Given:

Balance Deposited in account between September and December = $87.83

Now We need to find balance till December.

Kimmy balance till December will equal to sum of Balance in account in June and Balance in account till September and Balance Deposited in account between September and December.

framing in equation form we get;

Kimmy balance till December = $\$76.23+ \$381.15+\$87.83 = \$545.21$

Hence Kimmy balance in December will be $545.21.

Can someone please help. I don’t know how to do it.

ira [324]

Answer:

152 m^2

Step-by-step explanation:

Find the area of the triangle and subtract it from the area of the square

area of half-triangle = 1/2 x base x height = 1/2 x 8 x 13 = 52

since that's for half of the triangle we times it by 2 to get the whole triangle so 104.

area of the square = 16 x 16 = 256

area of shades region = 256 - 104 = 152 m^2
