First, find how many flowers are in 4 arrangements: 10*4=40
You can set this up as a proportion:
²/₁₀ = x/₄₀
You can also just multiply 2 daisies by 4 arrangements.
8 daisies
3000/30=100every day
100/25=4
So she buys 4 L of milk every day.
So t=4.
The sum angle of triangle is 180°
The angle of line is 180°
The right angle is 90°
x=180-115
x=65°
y=180-65-90
y=90-65
y=25
Answer:
Step-by-step explanation:
A=b^2+2bh
b = 3
A = 3^2 + 2(3)h
A = 9 + 6h
6h = A - 9
If you start counting from 0, you ninth term will be 8. Replace n=8 and calculate:
A(8) = -14 + (8-1)(2) = -14 + (7)(2) = -14 + 14 = 0
If you start counting from 1, your ninth term will be 9. Replace n=9 and calculate:
A(9) = -14 + (9-1)(2) = -14 + (8)(2) = -14 + 16 = 2
