If the amount of monkeys is m, lions is a, and lizards is b, then a+b+m=151, 17+a=m (since there are 17 more monkeys than lions), and 30+a=b. Substituting those values in (17+a=m and 30+a=b), we have 30+17+a+a+a=151=47+3a. Subtracting 47 from both sides, we get 104=3a. Next, we can divide both sides by 3 to get 104/3=a (the number of lions), 104/3+17=the number of monkeys, and 104/3+30=the number of lizards. Somehow we end up with a fraction (not a whole number), so there are 2/3rds of monkeys floating around using this logic.

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? square root of 8 units 4 units squa
ycow [4]
By the Pythagoras theorem, in a right triangle with the sides being a and b,

 a² + b² = Hypotenuse²

Hypotenuse² = 4² + 4²

Hypotenuse² = 16 + 16 = 2*16

Hypotenuse = √2 * √16

Thus, hypotenuse = 4√2

Convert 30,000 ML into L
lakkis [162]

Answer:

30 liters

Step-by-step explanation:

To me it's kind of like multiplying and dividing.

So, what I did was 30,000 divided by 30 and got 1,000.

1,000 x 30 = 30,000.

That's what I did. You probably have your own way of doing it, but the answer is 30. I'm sorry if my explanation isn't good enough but I tried. Thanks for the question and enjoy your answer :)

Answer a = 5 and b = 2.

Procedure

Initially means x = 0, then

5 = a*b^0 = a*1 = a, then a = 5

When x = 1, the height is the double of 5, i.e 10 and

10 = a.b^1 = a.b  ⇒  b = 10/a = 10/5 = 2

The a = 5 and b = 2, so the equation is y =5(2)^x
