4+5=9
63/9=7
7*4=28
7*5=35
If u add 28 and 35 the answer will be 63. I multiply the 4(blue bikes) to 7 and it equals to 28, so there are 28 blue bikes

Answer: (A - B)' = {1, 2, 3, 5, 6, 7, 8, 9, 10,12, 13}

Explanation:

The roster form of a set is the elements listed inside brackets { }.

In this case it is easy to visualize A - B directly of the Venn diagram: when you subtract from A those elements that are also in B, the result is A - B = {4, 11, 14}.

Now take into account tha (A - B)' is the complement of (A - B), this is all the elements that are not in A - B.

Being A - B = {4, 11, 14} then to show (A - B)' you just have to list all the elements that are on the figure except 4, 11 and 14.

The result, in roster form, is (A - B)' = {1, 2, 3, 5, 6, 7, 8, 9, 10, 12, 13}

If the amount of waking time 4 year old children spend with their fathers each day is 42 minutes while the daily waking time spe
telo118 [61]

Answer:

7/60

Step-by-step explanation:

Because the question is phrased such that it asks "the ratio of time with father <em>to...."</em>, we know to put the time with father on top, or first. Similarly, since it is asked to put the ratio of time with the father to the time in daycare, we can put the daycare amount second/on the bottom. Therefore, we can write the ratio as

(42 minutes)/(6 hours)

To make both of these in terms of minutes to simplify it, we know that 60 minutes = 1 hour, so 1 hour / 60 minutes =1 . Since multiplying something by 1 keeps it the same, we can multiply our ratio by this amount. We want to multiply with the hour on top so the hours cancel out, as so:

\frac{42 minutes}{6 hours} * \frac{1 hour}{60 minutes}  = \frac{42 minutes * hours}{360 minutes * hours} = \frac{42}{360}

To simplify this even further, we can note that 6 is a factor of both 42 and 360*, so we can multiply this fraction by (1/6) / (1/6) to get

(42/360) * (1/6)/(1/6) = 7/60 as our final answer

If this doesn't come up immediately, you can always find the greatest common factor by listing the factors of each number and finding the highest one that fits both, e.g.

for 42: 42, 21, 14, 7 , 6...

for 360: 360,180, ... 6,5....

For which intervals the graphs of the functions f(x) = x^3 + x^2 - 4x - 4 is positive
Nookie1986 [14]

Step-by-step explanation:

Consider a function

f

(

x

)

which is twice differentiable. The graph of such a function will be concave upwards in the intervals where the second derivative is positive and the graph will be concave downwards in the intervals where the second derivative is negative. To find these intervals we need to find the inflection points i.e. the x-values where the second derivative is 0.
