DedPeter [7]4 years ago
8 0

Answer:

a1 = 8

a2 =10

a3 = 13

a4 = 17

Step-by-step explanation:

The first term is a1 = 8

The second term is a2 = a1 + n

                                       = 8+2

                                       = 10

The third term is a3 = a2 + n

                                       = 10+3

                                       = 13

The fourth term is a4 = a3 + n

                                       = 13+4

                                       = 17

borishaifa [10]

Answer:

-6x +9

Step-by-step explanation:

You're apparently expected to recognize that equation solution processes generally involve eliminating parentheses using the distributive property. When you do this, you get ...

... (-3)(2x) + (-3)(-3)

... = -6x +9

_____

<em>Comment on the question</em>

Depending on the inequaltiy, you may want to divide by -3 first in your solution process. The question seems to assume there is One Right Way. In math, there is not.

# 6 The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m. What is the area of its base?
Lina20 [59]
<h3>The area of base is 0.25 square meter</h3>

<em><u>Solution:</u></em>

Given that,

The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m

To find: area of base

<em><u>The volume of cylinder is given as:</u></em>

V = \pi r^2h

The area of base of cylinder is area of circle

Area\ of\ circle = \pi r^2

Therefore,

V = base\ area \times height

From given,

h = 10 m

v = 2.5 kl

1 kilo liter = 1 cubic meter

Therefore,

2.5 kl = 2.5 cubic meter

Substitute height = 10 and volume = 2.5

2.5 = base\ area \times 10\\\\ base\ area = \frac{2.5}{10}\\\\ base\ area = 0.25

Thus area of base is 0.25 square meter
