She beat her goal by 1/12 of a mile.

3+3=6
1/3 multiply both numbers by 12. that gives you 4/12
3/4 multiply both numbers by 12. that gives you 9/12
add the numerators together. that gives you 13/12
12/12=1, so 13/12= 1 1/12

You add using the common denominator, 3 3/4 and 3 1/3 then you should get 7 1/12, to find the total miles. she ran 7 and 1/12th miles, so she ran a 12th mile over her goal.

Use the relationship between the angles in the figure to answer the question.
grigory [225]

Answer:

x = 52, A.

Step-by-step explanation:

The two angles across from each other are both acute angles, which means that considering their positioning, they're gonna equal the same in degrees. If the question were asking to find the value of x on one of the obtuse angles, your answer would be B, considering both of those lines would equal 180 degrees.

Hope that helps!

Much like sound bites of news​ stories, statistical studies are often reduced to​ one- or​ two-sentence "stat-bites." For the​st
Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Given that According to a video streaming​ service, 48% of American couples are​ "cheaters", that is—they promise each other to watch a film​together, but one of them first watches it alone.

Here if this is binomial with two outcomes we can easily say that the other 52% couples go together movies.

But here there are not only two outcomes.

The other possibilities are:

i) Either both do not go to movies

ii) Both cheat and go to movies separately

Thus since there are not exactly two outcomes, we cannot say the other 52% go to movies together.

As much as say that 52% of couples are not cheating in this way.
