Emily's credit card has arrived and she has a balance of $2,350. she only has enough money to pay off $1,500. she knows that she will have to pay 8% interest on whatever she doesn't pay off. which proportion should she use to determine how much interest she will have to pay?

.

Step-by-step explanation:

We are given that,

Balance in Emily's card = $2,350

Amount paid by Emily = $1,500

So, amount does not paid by her = 2350 - 1500 = $850.

Also, the interest on the amount not paid = 8% =

Thus, the proportion representing the interest she has to pay is given by,

i.e. Proportion = .

Hence, the required proportion is .

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
