Answer:

3 > x

Step-by-step explanation:

-10 + 8x < 6x - 4

Subtract 8x from each side

-10 + < -2x - 4

Add 4 to each side

-6 < -2x

Divide each side by -2 remembering to flip the inequality

-6/-2 > -2x/-2

3 > x

The length of a rectangle is three times its width. if the area of the rectangle is 75 in2, find its perimeter.

UkoKoshka [18]

Answer:

40 in

Step-by-step explanation:

For a width of w, the length is 3w and the area and perimeter are ...

A = LW = (3w)(w) = 3w^2

P = 2(L+W) = 2(3w +w) = 8w

We are given the area, so we can find w to be ...

75 in^2 = 3w^2

25 in^2 = w^2 . . . . . divide by 3

5 in = w . . . . . . . . . square root

Then the perimeter is ...

P = 8w = 8(5 in) = 40 in

What is the sum of the first five terms of a geometric series with a1=15 and r=1/3

Solnce55 [7]

Answer:

15, 5, 5/3, 5/9, 5/27

Step-by-step explanation:

Recall, that the general form of a geometric series is

a, ar, ar², ar³, .........

where a is the first term and r is the ratio

It is given that the first time is 15, hence a = 15

also given that ratio is 1/3

hence the first 5 terms are:

15, (15)(1/3), (15)(1/3)^2, (15)(1/3)^3, (15)(1/3)^4

simplifying each term gives

15, 5, 5/3, 5/9, 5/27

Which of the following do not have precise definitions in geometry. Select the two correct answers

guapka [62]

Answer:

2 and 5

Point and line.

Step-by-step explanation:

In geometry, there are many terms and jargons Mathematicians make use of.

Angle is one of the term used in geometry which depicts any form of inclination.

Segment is also use to analyze and to solve many questions.

Lines are used to join one segment or the other.

Point and ray are also used but are majorly used in optics

Asking that Which of the following do not have precise definitions in geometry.

The best answer are point and line.

Because there is no specific definition for the two variables.

What is the next term of AP : √2, √8, √18, .......?

solmaris [256]

Answer:

$\sqrt {32}$

Step-by-step explanation:

Next term of the given AP can be obtained by adding common difference (d) in the last term $\sqrt {18}$

$d = \sqrt{18} - \sqrt{8} = 3 \sqrt{2} - 2 \sqrt{2} = \sqrt{2} \\ next \: term = \sqrt{18} + \sqrt{2} \\ = 3 \sqrt{2} + \sqrt{2} \\ = 4 \sqrt{2} \\ = \sqrt{ {4}^{2} \times 2 } \\ = \sqrt{16 \times 2} \\ \huge \red{ \boxed{next \: term = \sqrt{32} }}$
