5 x 10 is 50 then 50 + 11 is 61 so I think it would be 61 ;)
Answer:
10
Step-by-step explanation:
5x+37=87
5x=87-37
5x=50
X=50÷5
X=10
Given:
Inner cone: diameter = 12 cm ; height = 6 cm
Outer layer: diameter = 12 cm ; height = 15 cm
Volume of a cone = π r² h/3
Inner cone: V = 3.14 * (6cm)² * 6cm/3 = 3.14 * 36cm² * 2cm = 226.08 cm³
Outer layer: V = 3.14 * (6cm)² * 15cm/3 = 3.14 * 36cm² * 5cm = 565.20 cm³
Volume of Outer layer : 565.20 cm³
less: Volume of inner layer:<u> 226.08 cm³</u>
Volume of cream filling: 339.12 cm³
X^2 + 3x = 24
completing the square
(x + 1.5)^2 - 2.25 = 24
(x + 1.5)^2 = 26.25
x + 1.5 = +/- sqrt26.25 = +- 5.123
x = -1.5 + 5.123 = 3.62 to nearest hundredth and
x = -1.5 - 5.123 = -6.62 to nearest hundredth
solution set is {-6.62, 3.62}
