Answer:

9 and 3

Step-by-step explanation:

10/15=6/(2x-9)

90=10(2x-9)

9=2x-9

x=9

18-8=10

10/(4x+3)=8/12

120=8(4x+3)

30=8x+6

The diameter of a sphere is 4 centimeters.

ELEN [110]

The volume of a sphere refers to the number of cubic units that will exactly fill a sphere. The volume of a sphere can be found or calculate by using the formula V=4/3πr^3, where r represents the radius of the figure.

In this exercise is given that a sphere has a radius of 4 centimeters and it is asked to find its volume and use 3.14 as the value of π or pi. The first step would be substitute the values into the previous mention formula.

V=4/3πr^3
V=4/3(3.14)(4 cm)^3
V=4/3)(3.14)(64 cm^3)
V=267.9 cm^3
The volume of the sphere is 267.9 cubic centimeters.

For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches

pashok25 [27]

Answer:

Option 1st is correct

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$

Step-by-step explanation:

Area of the triangle is given by:

$A = \frac{1}{2}bh$

where,

A is the area of the triangle

b is the base and

h is the height of the triangle.

As per the statement:

For a project, you need to make three triangles out of cardboard.

Each triangle has a height of 5 inches and a base of 10 inches

⇒b = 10 inches and h = 5 inches

$\text{Area of each triangle} = \frac{1}{2} \cdot 10 \cdot 5$

Since, you need to make three triangles out of cardboard

⇒ $\text{Area of 3 triangle}(x) =3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)$

Therefore, an equation can you use to solve for the total amount of cardboard you will need is,

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$
