Answer:

Both are terminating decimals

Step-by-step explanation:

Answer to your questions:

First of all, both A and B are correct and both quotients are terminating decimals.

To find out if the decimal is terminating or not, multiply the quotient by divisor. If you get exactly the same number as dividend, then it is terminating otherwise it is non-terminating.

The fraction may have greater numerator than denominator, in this case the quotient will be greater than one.
Now regarding simplification. You would be asked to give an answer rounded to some extend. One decimal place, two decimal places, 3 significant numbers etc. For the first operation you would get 34.8 (rounded to nearest tenth).
Or you may be asked to have a best estimated result. In this case you would round the initial numbers and find results. 205/714 ≈ 0.29

Help me out please simple

const2013 [10]

A straight line is 180 degrees in measure

The straight line is made up of three angles

--> angle 1

--> angle 2

--> angle with a little square on it

(angle with a little square means it is 90 degrees in measure)

Let's set up an equation

$angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3$

Thus angle 1 is 3 degrees or the second choice

Hope that helps!

Calculate the number of subsets and the number of proper subsets for the set.

arlik [135]

A set of n elements has 2ⁿ subsets. One of these subsets is the set itself, so this set would have 2ⁿ - 1 proper subsets.

The given set has 4 elements, so it has 2⁴ = 16 subsets and 2⁴ - 1 = 15 proper subsets.

Just to illustrate the claim, we have

• subsets of size 0 (1 of these):

{ } (empty set)

• subsets of size 1 (4 of these):

{1/6}, {1/7}, {1/8}, {1/9}

• subsets of size 2 (6 of these):

{1/6, 1/7}, {1/6, 1/8}, {1/6, 1/9}, {1/7, 1/8}, {1/7, 1/9}, {1/8, 1/9}

• subsets of size 3 (4 of these):

{1/6, 1/7, 1/8}, {1/6, 1/7, 1/9}, {1/6, 1/8, 1/9}, {1/7, 1/8, 1/9}

• subsets of size 4 (1 of these):

{1/6, 1/7, 1/8, 1/9}

and the last one is the only subset that is not a proper subset, because that subset = the set.

I need help on how to do Angle Relationships.

mote1985 [20]

Answer:

it would be 50

Step-by-step explanation:

i would be 50 because you have to multiply 2 by x and then add 10 to get 110 degrees so that would look like this 2 * 50 + 10 = 110 degrees
