If 150 chocolate chip cookies are 15% of the days production, then we may write it down as:
150 = 15% from x
150 = 15/100x
150 = 3/20x / * 20 (both sides)
3000 = 3x / ÷ 3 (both sides)
<u>x = 1000</u>
Answer: I planned producing 1000 cokies that day.
All the points in the doubly-shaded area are in the solution set.
Answer:
75cm²
Step-by-step explanation:
10×15=150
150÷2=75cm²
Answer:
4.46cm
Step-by-step explanation:
Volume of a frustum is expressed as;
V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))
h is the height of the frustum
r₁ and r₂ are the radii of its ends
V is the volume
Given
V = 9100cm₃
r₁ = 10cm
r₂ = 30cm
Substitute
9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))
9100 = 1/2(3.14)*h*(100+900+300)
9100 = 1.57*h*(1300)
9100 = 2,041h
h = 9100/2,041
h = 4.46cm
Hence the height of the cap is 4.46cm
