Step-by-step explanation:
Answer:
b = 2A/h
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh where b is the base and h is the height
We want to find the base
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by the height
2A/h = bh/h
2A /h = b
b = 2A/h
Answer:4
Step-by-step explanation:
I don’t know I just chose a answer
The number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
If you would like to know how many scented and how many unscented candles did the shop sell today, you can calculate this using the following steps:
x + y = 28 ... x = 28 - y
16 * x + 10 * y = 400
____________________
16 * (28 - y) + 10 * y = 400
16 * 28 - 16 * y + 10 * y = 400
448 - 400 = 16 * y - 10 * y
48 = 6 * y /6
y = 48 / 6
y = 8
x = 28 - y = 28 - 8 = 20
Result: The candle shop sold 20 scented candles and 8 unscented candles today.
A(n)=a × r^n-1
A(12)= 14 x 1.03^11
A(12)=19.379
