15/6=2.5 which is the scale factor since they are similar triangles. We divide each side of the large triangle by 2.5 to get the sides for the small triangle since they are similar. 20/2.5=8cm
25/2.5=10cm

For the second problem, you put 15/6 and set in equal to x/8 when you cross multiply you get 6x=120 then you divide x=20

For the last problem, you divide 43,75 by 5 then multiply it by 400 to get the kiloliters which equals 3,500.

12345 [234]

Answer:

A choice.

Step-by-step explanation:

Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.

From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.

B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.

For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.

What is the solution to the system of equation <br><br> -2x+6y=-38<br> 3x-4y=32
Alla [95]

Answer:

x= 4

y= -5

Step-by-step explanation:

-2x+6y=-38    equation 1

3x-4y=32     equation 2

using equation 1 we have:

-2x+6y=-38  

6y +38 = 2x

3y + 19 = x   equation 3

using equation 3 in equation 2 we have:

3(3y + 19) - 4y = 32

9y + 57 -4y =32

5y = 32 -57

5y = -25

y= -25/5

y = -5

so we have:

3y + 19 = x  

3(-5) +19 = x

x= 4
