Answer:

27.5

Step-by-step explanation:

tens ones . tenths hundredths thousandths

2 7 . 5 3 9

Rounding to the nearest tenth means we look at the hundredth

3 <5 so we leave it alone

A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.

Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.

What is the image of (12, -9) after a dilation by a scale factor of 1/3 centered at the origin

erica [24]

Answer:

(4,-3)

Step-by-step explanation:

The scale factor is 1/3. So, multiply the numbers by 1/3.

12*1/3 is 4.

-9*1/3 is -3.

The new coordinates are (4,-3).

A sphere has a radius of 5 inches. What is its volume?

jarptica [38.1K]

Given ↓

Radius of sphere = 5 in

<h3>To Find ↓</h3>

The volume of the sphere

<h3>Calculations ↓</h3>

$\blue{\boxed{\mathsf{V=\frac{4}{3} \pi r^3}}$

↑ formula for volume of a sphere

r = 5 in

Plug in the value of r and solve :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi (5)^3}}}$

Simplify as follows :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi *125} }}$

$\blue{\boxed{V=\frac{4}{3} *392.7}}$

Final Step :

$\blue{\boxed{\pmb{V=523.6\:in\:^3}}$

There are many cylinders with a height of 18 meters. Let represent the radius in meters and represent the volume in cubic meters

antiseptic1488 [7]

Answer:

Step-by-step explanation:

1). Equation that represents the volume of a cylinder,

V = πr²h

Here, r = radius of the cylinder

h = Height of the cylinder

2). Fromm the given formula of volume,

r(In m) V(In cubic meters)

1 56.55

2 226.19

3 508.94

3). If the radius is doubled from 1 m to 2 m,

At r = 1 m, Volume (V₁) = 56.55 m³

At r = 2 m, Volume (V₂) = 226.19

$\frac{V_2}{V_1}=\frac{226.19}{56.55}$

= 4

Therefore, volume is not doubled when radius of the cylinder is doubled.

Which expression is equivalent to 2(x + 5) + 5x?<br>a)2x + 10<br>b)7x + 5<br>c)7x + 10<br>D)10x + 5

White raven [17]

Answer:

C. 7x+10

Step-by-step explanation:

First, distribute the 2

2(x+5) +5x

2*x+2*5 +5x

2x+10+5x

Combine like terms

2x+5x+10

7x+10

So, C is the correct answer

Hope this helps! :)
