33. Whether your dividing perfect squares in a square root or separately in the numerator or denominator, the solutions will remain the same.

34. the square root of a perfect square would be a while number and its opposite. The Difference of the two must equal 30, therefore 15 - (-15) = 30 so 30 squared is 900. a is 900.

If you toss a coin and spin the spinner, what is the probability of landing on heads and spinning blue?

ivann1987 [24]

Answer:

Step-by-step explanation:

There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.

How many solutions are there to the equation below?

Elza [17]

Answer:

no solution

Step-by-step explanation:

heres why:

Let's solve your equation step-by-step.

4x−9(x+1)=20−5x

Step 1: Simplify both sides of the equation.

4x−9(x+1)=20−5x

4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)

4x+−9x+−9=20+−5x

(4x+−9x)+(−9)=−5x+20(Combine Like Terms)

−5x+−9=−5x+20

−5x−9=−5x+20

Step 2: Add 5x to both sides.

−5x−9+5x=−5x+20+5x

−9=20

Step 3: Add 9 to both sides.

−9+9=20+9

0=29

so there are no solution

How do you write 0.045 as a reduced fraction

Anvisha [2.4K]

0.045 = 45/1000

Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of 45 and 1,000 is 5 .
Divide top and bottom by 5 and we have 9/200 . That's the simplest form.
