The first picture is for number 1 and the second one for number 2.
Answer:
Answer is $10,144.50
Step-by-step explanation:
15% of 220 =33
220- 33 = 187
8.5% of 187 =15.89
187+15.89=202.89
202.89 x 50 =10,144.50
First notice that the triangle with sides

and the triangle with sides

are similar. This is true because the angle between sides

in the smaller triangle is clearly

, while the angle between sides

in the larger triangle is clearly

. So the triangles are similar with sides

corresponding to

, respectively.
Now both triangles are

, which means there's a convenient ratio between its sides. If the length of the shortest leg is

, then the length of the longer leg is

and the hypotenuse has length

.
Since

is the shortest leg in the larger triangle, it follows that

, so
Answer:
The next three terms are 10, 12.5 and 15
Step-by-step explanation:
I. As you can see 5 and 7.5 is came from 5, 5 + 2.5
So given y = 5 + 2.5( x - 1 ) when y is output, x is term
II. Perform x = 3, 4, 5
So y = 5 + 2.5( 3 - 1 )
= 5 + 5
3rd = 10
y = 5 + 2.5( 4 - 1 )
= 5 + 7.5
4th = 12.5
y = 5 + 2.5 (5 - 1)
= 5 + 10
5th = 15
