Answer:
Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
Step-by-step explanation:
Given:
Total Money paid for stamps = $14.84
Let the number of 49-cents stamps be x.
Also Let the number of 21-cents stamps be y.
Now Total Money paid is equal to sum of number of 49-cents stamps and number of 21-cents stamps.
100 cents = 1$
So 49 cents = $0.49
and 21 cents = $0.21
Hence equation be framed as;
Also Given:
number of .49-cents stamps was four less then three times the number of 21-cent stamps.
hence we can say that;
Now Substituting the value of equation 2 in equation 1 we get;
Now substituting the value of y in equation 2 we get;
Hence Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.

Answer:
3 vertices
Step-by-step explanation:
Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices.
Answer:
0.5+8
Step-by-step explanation:
The slope intercept form is mx+b
Mx is the slope
b is the y intercept
The slope formula is y2-y1/x2-x1
2 points to find the slope:
(2,9) (4,10)
10-9=1
4-2=2
1/2=0.5
The y-intercept is the number that goes through the number line when x equals 0. The y intercept is 8.

<u>2. </u><u>find</u><u> </u><u>cos Ф, sin Ф, tan Ф</u>
cos Ф = 5 / 13
Ф = 67.38
sin Ф = 12 / 13
Ф = 67.38
tan Ф = 12 / 5
Ф = 67.38
-----------------------
<u>3. find sin β, cos β, tan β</u>
sin <u>β</u> = 4 / 5
<u>β</u> = 53.13
cos <u>β</u> = 3 / 5
<u>β</u> = 53.13
tan <u>β</u> = 4 / 3
<u>β</u> = 53.13
