Answer-
B the relation is not a function
13
Answer: 175.8 cm^2
Explanation:
The formula for calculating the area of a sector is expressed as
Area = θ/360 x πr^2
where
r is the radius of the circle
θ is the angle subtended at the center
From the information given,
θ = 315
r = 8
π = 3.14
By substituting these values into the formula,
Area of sector = 315/360 x 3.14 x 8^2
Area of sector = 175.8 cm^2
Answer:
£70.00
Step-by-step explanation:
You basically want to find what she spent in total, then subtract the amount she spent on ingredients.
50 glasses of lemonade at £2.10 each would be £105. (50*2.1)
Subtract the cost of ingredients, which is £35, with the total she made, £105, to get £70 (105-35)
Answer:
20
Step-by-step explanation:
The triangles are similar so we can use ratios
8 32
--- = -----
8+5 32+x
Using cross products
8(32+x) = 32(13)
Divide each side by 8
(32+x) = 32(13)/8
32+x = 4*13
32+x =52
Subtract 32
x = 20
