(48.15 - 45) / 45 = 3.15 / 45 = 0.07 = 7% <== rate of sales tax
Answer:
45.25 in
Step-by-step explanation:
To solve this question you would plug 7/2 or 3.5 in for t and solve for h(t).
h(t)=-3(7/2)^2+12(7/2)+40
=-3(49/4)+(84/2)+40
=(-147/4)+42+40
=-36.75+42+40
=45.25 in
Hello : here is a solution
<em>Rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>
<h2>
Explanation:</h2><h2 />
The aspect ratio is defined as:
<em>"The proportional relationship between the width and height of an image"</em>
It is usually expressed in a mathematical language as:
So, it is true that:
In this case, we know that the monitor has a diagonal length (D):
So, by Pythagorean theorem:
Finding x:
<em>Finally, rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>

Answer:
option 2 with radius of 1.4 in, and height of 1.2 in.
Step-by-step explanation:
If two cylinders are similar, the ratio of one cylinder's radius to its height must be the same as that of the other.
To know which cylinder is similar to the given cylinder with radius 2.8 in and height of 2.4 in, find the ratio, and compare with the ratio of the options provided. The option with the same ratio, is the cylinder that is similar.
This,
The given cylinder => radius : height =
First option:
Radius : height =
Second option:
Radius : height =
Third option:
Radius : height =
Fourth option:
Radius : height =
The correct option with the cylinder that is similar with the given cylinder is option 2 with radius of 1.4 in, and height of 1.2 in.
