Answer:
50 cups
Step-by-step explanation:
ratio of water to juice = 10 : 6 = 5 : 3
amount of cup = (5 x 30) / 3 = 50
The equation and steps are...
First, find the slope of the original equation. In this case, the slope is -8. You know that perpendicular lines have slopes that are negative reciprocals, so the negative reciprocal of -8 is 1/8.
Now, use this new slope and the given point to find the y-intercept:
y = mx + b
4 = (?)(2) + b
4 = ? + b
15/4 = b
Use the new slope and y-intercept to write the new linear equation:
Answer:
y = 1/8x + 15/4
Sorry if i'm wrong

Answer:
100°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°
∠ECD = 40° ( vertical angle to ∠ACB )
Since CE ≅ ED then ΔCDE is isosceles and
∠CDE = ∠ECD = 40°
∠E = 180° - (40 + 40)° = 180° - 80° = 100°
$265.32
r = R/100
r = 4/100
r = 0.04 rate per year,
A = P(1 + r/n)nt
A = 1,000.00(1 + 0.04/1)(1)(6)
A = 1,000.00(1 + 0.04)(6)
A = $1,265.32
1,265.32-1,000=265.32
