A number is written with the following factorization 2x2x2x4x5. Is this factorization is prime factorization? Explain why or why
Ulleksa [173]
The number 2*2*2*4*5 is not in its prime factorization because not all the factors are prime numbers. A prime number is a number that has no other factors except for 1 and itself.
4 is not a prime number, since it can be divided by 2. The number can be broken down into its prime factors by dividing by 2, and it becomes 2*2.

Therefore, the factorization of the number 2*2*2*4*5 can be broken down to 2*2*2*2*2*5.

Ian has 12.2 ounce bottle of ketchip. He uses 1/20 of the ketchup every time he has a buffalo burger How many ounces of ketchup
tatiyna
If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or \frac{4}{20}.

\frac{4}{20} can be simplified to \frac{1}{5}, which means we need to work out \frac{1}{5} of 12.2

\frac{1}{5} is equivalent to 20%, which as a decimal is 0.2

0.2 x 12.2 = 2.44 - however, this is how much he has used, and we need to figure out how much is left.

12.2 - 2.44 = 9.76

So, Ian has 9.76 oz remaining :)

Can someone at least have an estimate of how much money you will need to buy things fro your new house.. ( I mean everything inc
gregori [183]

Answer:

You’ll have to come up with $10,000 - 25,000.

Step-by-step explanation:

You'll need at least this much for your new house because if you think about it appliances are getting expensive. So, is furniture and it also depends on how big the house is. Then again, this is about how much my parents ( $46, 560 ) spent on our house and we still are looking for more furniture.

In the diagram of circle O, what is the measure of abc? 34° 45° 68° 73°
Lady_Fox [76]

Answer:

A. m\angle ABC=34^{\circ}

Step-by-step explanation:

We have been given a diagram. We are asked to find the measure of angle ABC.

First of all, we will find measure of major arc AC by subtracting 146 from 360 degrees.

\text{Measure of arc AC}=360^{\circ}-146^{\circ}

\text{Measure of arc AC}=214^{\circ}

Now, we will use tangent-tangent angle theorem to solve for ABC.

Tangent-Tangent angle theorem states that angle formed by two tangents outside a circle is half the difference of intercepted arcs.

m\angle ABC=\frac{214^{\circ}-146^{\circ}}{2}

m\angle ABC=\frac{68^{\circ}}{2}

m\angle ABC=34^{\circ}

Therefore, the measure of angle ABC is 34 degrees and option A is the correct choice.
