1 answer:

3 0

1. What is 8 increased to 22.
I believe you want me to show you what is the interest increased from 8 to 22
Let’s start the solution process:
=> 8 is the original number and supposed to be the 100% value
=> 22 is the increased number
subtract 22 by 8 to know how much is added.
=> 22 – 8 = 14
=> 14 / 8 = 1.75
=> 1.75 * 100% = 175%
Thus, the added increased is around 175% of the original money

An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20\text{ cm}d=20 cmd, equals, 20, s

aivan3 [116]

Answer: The answer is 314.28 cm² (approx.).

Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.

We need to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is

$\textup{d}=20~\textup{cm}.$

So, the radius of the circular cross-section will be

$\textup{r}=\dfrac{\textup{d}}{2}=\dfrac{20}{2}=10~\textup{cm}.$

Therefore, cross-sectional area of the pipe is

$\textup{A}=\pi \textup{r}^2=\dfrac{22}{7}(10)^2=\dfrac{2200}{7}=314\dfrac{2}{7}=314.28~.~.~.~\textup{cm}^2.$

Thus, the answer is 314.28 cm² (approx.).

Which of the following are geometric series?

Temka [501]

Answer:

-256 +64 - 16 + 4 - 1

Step-by-step explanation:

A series is the summation of all the terms in a sequence.

So it is only the last three options that qualify to be a series.

The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.

The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.

The series -256 +64 - 16 + 4 - 1 has a common ratio of

$r=\frac{64}{-256}=-\frac{1}{4}$

There the only series that is geometric is.

-256 +64 - 16 + 4 - 1

Given the point and its image, determine the scale factor. B(2,5) B'(1,2.5) 0 -1/2 02 0-2 O 1/2

fiasKO [112]

Given:

The point is B(2,5) and its image is B'(1,2.5).

To find:

The scale factor.

Solution:

If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as

$k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}$

x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is

$k=\dfrac{1}{2}$

Therefore, the scale factor is $\dfrac{1}{2}$ and the correct option is D.
