A scoop of ice cream is the shape of a whole perfect sphere sits in a right cone.

Andrei [34K]

Answer:

10 cm

Step-by-step explanation:

The volume of a sphere is given by the formula ...

V = 4/3πr³

The volume of a cone is given by the formula ...

V = 1/3πr²h

The ratio of the volume of the cone to that of the sphere is ...

Vcone/Vsphere = (1/3πr²h)/(4/3πr³) = h/(4r)

In order for the ratio to have a value of 1, we must have ...

h = 4r

The height of the cone must be 4×2.5 cm = 10 cm to fit all of the ice cream.

Help please. Having some trouble with this question

xeze [42]

Answer:

The answer to your question is 55 ft

Step-by-step explanation:

Data

Person's height = 5 ft

Person's shadow = 10 ft

Tree's height = ?

Tree's shadow = 110 ft

- Use the Thales' theorem to solve this problem

Person's height / Person's shadow = Tree's height / Tree's shadow

- Substitution

5 / 10 = x / 110

-Solve for x

x = 5 (110) / 10

-Simplification

x = 550 / 10

-Result

x = 55 ft

-Conclusion

The tree is 55 ft height

2. What is the value of x if the angles<br> within a triangle are 2x +1, 7x-2 and 3x<br> +5?

noname [10]

Answer:

$x=14.67\\$ °

Step-by-step explanation:

The sum of all the three angles of any triangle is 180°

Putting sum of all the angles given equals to 180°

$(2x+1)+(7x-2)+(3x+5)=$ $180$ °

$2x+7x+3x+1-2+5=180$ °

$12x+4=180$ °

$x=\frac{180-4}{12}$

$x=14.67\\$ °

The value of the x is found on solving the given angles of the triangles.
