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}

Please help I will mark brainlist if correct

Hi there!

Since the slope of a line perpendicular to a line is always the negative inverse of that slope, you just switch the numerator and denominator around and add or omit the negative sign to the original slope.

The answer would be -2.

Hope this helps!

When a certain polynomial is divide by binomial x-3, the result is 4x-5+6/x-3. What is the polynomial
Dmitry_Shevchenko [17]
\frac{p(x)}{x-3} = 4x-5 + \frac{6}{x-3}

The polynomial p(x) can be found by multiplying 'x-3' to every term
p(x) = (4x-5)(x-3) + 6

Now distribute and you have your answer.
p(x) = 4x^2 -12x-5x+15 +6 \\  \\ p(x) = 4x^2 -17x+21

Vsphere=(4/3)pir^3


given

cylinderradius=30 and h=100
Vcylinder=100pi30^2=100pi900=90000pi
let's leave it in terms of pi for more exactness

sphereradius=12
Vsphere=(4/3)pi12^3=2304pi


cylinder-sphere=90000pi-2304pi=87696pi
using pi=3.14
water=275365.44 cubic cm

last option is corrrect
