Well you can make a proportion to see if the values (2 miles in 1/2 hour and 1 mile in 15 minutes) are equal to each other or not. 

**We need to convert 15 minutes into hours --> 15 minutes / 60 minutes = 1/4 hour \frac{2 \text{ miles}}{ \frac{1}{2} \text{ hours} }  =  \frac{1 \text{ mile}}{ \frac{1}{4} \text {hour}}

Cross-multiply...
1/2(1) = 2(1/4) <em>*is this true? </em>
1/2 = 2/4 <em /><em>*if you simplify 2/4 by dividing the numerator and denominator by 2 you get 1/2
</em><em />1/2 = 1/2 <em>**this is correct!</em>

So it is true!

2 miles = 1/2 hour (a whole hour is 60 mins so half of that is 30 mins) 1 mile = 15 mins (15 mins is half of 30 mins) so yes its true

What angles go with the angle pairs? Just a simple checklist please :).​
Anni [7]

Answer:

Here is the answer

Step-by-step explanation:

∠1 and ∠6 are adjacent because they share the same vertex and the same common side.

∠2 and ∠5 are vertical angles since they have pairs on opposite sides of the angle.

∠3 and ∠6 have none of the above.

∠5 and ∠3 are a linear pair because the angles are opposite of each other.

Is FGH ~ JKL? If so, identify the similarity postulate or theorem that applies.
Leokris [45]
Yes, for triangles to similar two angles have to be the same, in this case, they both have 55 and 30 degrees), this makes the third angle the same. Triangles angles add up to 180 degrees and if you subtract 30 and 55 from 180..
180-30=150-55=95
95+30+55=180

The value of y varies directly with x and y=3 when x=-6. Find y when x=1
Iteru [2.4K]
Hi, ok all you need to do is use the direct variation formula which is= y/x=y/x so you will replace your numbers by each value which get us to = 3/-6=y/1 so you cross multiply which gives us 3=-6y you divide 3 by -6 and that is the value of y, thank you for reading hope it helps ;)

britney is buying a hat at the mall. the shirt costs $31.59, and the hat costs $19.46. if Britney gives the sales clerk $100.00,
kiruha [24]

Answer: 48.95

Step-by-step explanation:

so first I would add together the cost of the shirt and hat

31.59 +19.46 = 51. 05

then I would take away the 51.05 ( the total ) from $100

100 - 51.05 = $48.95

So she would get $48.95 for change
