Answer:
20 nickels and 26 dimes
Step-by-step explanation:
- She has $3.60 in nickels and dimes
- a nickel is $0.05 and a dime is $0.10
- let n be the number of nickels and d be the number of dimes
- thus the first equation is 3.6 = 0.05n +0.1d
- If she has 46 coins then n + d = 46
- then n = 46 - d
- sub n = 46 - d into 3.6 = 0.05n +0.1d
- 3.6 = 0.05(46 - d) + 0.1d
- 3.6 = 2.3 -0.05d+0.1d
- 1.3 = 0.05d
- 26 = d
- sub d = 26 into n+d=46
- n+26=46
- n=20
- Check by subbing n=20 and d=26 into 0.05n +0.1d
- 0.05(20) +0.1(26)
- 1+2.6 = 3.6
Answer: 16.6% percent chance she will pull out a blue or orange marker.

Answer:
b ≈ 8.60 ft
Step-by-step explanation:
The formula of a parallelogram is
A = bh
Divide each side by h
b = A/h
b = 62⅓/7¼
b = (187/3) ÷ (29/4)
b = 187/3 × 4/29
b = 748/87
b = 8⁵²/₈₇ ft
b ≈ 8.60 ft
The base of the window is about 8.60 ft long.
