Answer:

Step-by-step explanation:

r = 9 cm

h = 10 cm

Volume of cone = (1/3)πr²h

$=\frac{1}{3}*3.14*9*9*10\\\\=3.14*3*9*10\\$

= 847.8 cubic cm

tresset_1 [31]

x = 3.5y equation shows the number of teaspoons of sugar, y, needed to make x tarts.

What is the linear equation in two variable?

Any equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero, is called linear equation in two variable.

According to the given question

A recipe require 3.5 teaspoons of sugar to make a tart.

y represents the number of teaspoons of sugar.

x represents the number of tarts.

Now, for x tart 3.5y teaspoons of sugar required.

⇒ x = 3.5y

Hence, the linear equation in two variable that shows the number of teaspoons of sugar y, needed to make x number or tarts is x = 3.5y.

There are three times as many people at the baseball park today than there were yesterday. Today’s attendance is 15,000. Define

Verizon [17]

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance

Step-by-step explanation:

There are three times as many people at the baseball park today than

there were yesterday

Assume that the number of the people at the baseball park

yesterday is x

∵ The number of the people at the baseball park yesterday = x

∵ The number of people at the baseball park today is three times

as many as the number of the people yesterday

∴ The number of people at the baseball park today = 3 x ⇒ (1)

∵ Today’s attendance is 15,000

∴ The number of people at the baseball park today = 15,000 ⇒ (2)

- Equate (1) and (2)

∴ 3 x = 15,000

- To find the value of x solve the equation:

3 x = 15,000

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance

| x+4 | = 5 Solve the absolute value equation or indicate that the equation has no solution.

vladimir2022 [97]

| x + 4 | = 5

x + 4 = 5 x + 4 = -5
x = 5 - 4 x = -5 - 4
x = 1 x = -9

solution : x = 1 and x = -9
