Answer:
Step-by-step explanation:
nth term = a +(n-1)d
a3 = 116 ; a + 2d = 116 ---------(i)
a7 = 180; a + 6d = 180 -------(ii)
multiply (ii) by -1. so a will be eliminated
a + 2d = 116 ---------(i)
(ii)*-1 <u>-a - 6d = -180</u> -------(ii) { Now add the two equations}
- 4d = -64
d = -64/-4
d = 16
Plug in the value of d in equation (i),
a + 2*16 = 116
a + 32 = 116
a = 116 - 32
a = 84
12th term = 84 + 11* 16 = 84 + 176 = 260
Silver beads = 75
gold beads = 15
75/15 = 5
5/1, or for every 1 gold bead there is, there is 5 silver beads
5 is your answer

Answer:
13 foot rounded to the nearest foot
Step-by-step explanation:
the ratio is
nose to head: 2:9
Rushmore mountain Roosevelt :
nose to head : x/60
2/9=x/60
120=9x
x=120/9= 13 1/3 or 13.33
x=13 foot rounded to the nearest foot
