) a smart phone has dimensions of 4.9 inches (height), 2.3 inches (width) and 8.0 millimeters (depth). what is the volume of the

mariarad [96]

Answer: 58.11 cm³

Step-by-step explanation:

1. The volume can be calculated with the following formula:

$V=h*w*d$

Where <em>l</em> is the lenght, <em>w</em> is the width and <em>h</em> is the heigth of the smartphone.

2. You know that the dimensions are:

$h=4.9in\\w=2.3in\\d=8mm$

3. Convert the height and the width from inches to centimeters, as following:

$h=\frac{4.9in*2.54cm}{1cm}=12.44cm$

$w=\frac{2.3in*2.54cm}{1cm}=5.84cm$

4. Convert milimeters to centimeters:

$d=\frac{8mm}{10}=0.8cm$

4. Then, the volume is:

$V=(12.44cm)(5.84cm)(0.8cm)=58.11cm^{3}$

What is the equation of the line that passes

Afina-wow [57]

Answer:

Step-by-step explanation:

First, find the slope of the line for the two points.

Slope is Rise/Run.

For the two points (-8,-4) and (3,-10):

Rise (-10 - (-4)) = -6

Run (3 - ( -8)) = 11

The slope is Rise/Run or -(6/11)

The equation becomes y = -(6/11)x + b

Find b by entering either of the 2 points given. I'll use (3,-10):

y = -(6/11)x + b

-10 = -(6/11)(3) + b

b = -10 + (6/11)(3)

b = -10 +(18/11)

b = -(110/11) + (18/11)

b = -(92/11)

The equation becomes y = -(6/11)x - (92/11)

John wants to construct a dog pen at the back of his garage. he will use the wall of the garage as one side of the pen and will

Komok [63]

If . he will use the wall of the garage as one side of the pen and will construct the rest of the rectangular pen from 28 yards of fencing. The maximum area that can be achieved for the dog pen is: 392 yards².

<h3>Maximum area </h3>

Let x represent the width of the fence

Let the two widths represent 2x

Let the length of one side represent 28-x

Let A represent Area

Hence,

A=x(28-x)

=-x²+28x

Using calculus or vertex = -b/2a,

x value = -28/-2

x = 14

2x = 28

So,

Maximum area= 14 ×28

Maximum area = 392 yards²

Therefore the maximum area is 392 yards².

nevsk [136]

Answer:

13

Step-by-step explanation:

Given:

Square stickers that were 3/4 in long
The spine is 10 and 1/2 in long

If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:

$\frac{The length of the spine}{the length of the sticker}$

10 : $\frac{3}{4}$ ≈13

She needs 13 stickers cover the length of the spine
