Each side of a square is increasing at a rate of 4 cm/s. at what rate is the area of the square increasing when the area of the

Iteru [2.4K]

Confusing question but I would get 0, as if you have 4cm, that squared = 16cm^2. Therefore if it were increasing anymore, then you would not be able to get a value of 16.

The small sign's perimeter is 36 inches

Step-by-step explanation:

The scale factor between two figures is obtained by:

$Scale = \frac{P_{l}}{P_{s}}$

So,

We know that

$Scale= 5:3\\P_l = 60\ in\\$

Putting the values in the above equation of scale factor we get

$\frac{5}{3} = \frac{60}{P_s}$

Cross multiplication

$5 * P_s = 60*3\\5P_s = 180$

Dividing both sides by 5

$\frac{5P_s}{5} = \frac{180}{5}\\P_s = 36$

Hence,

The small sign's perimeter is 36 inches

Triangle sum and exterior angle theorem.

wlad13 [49]

Did two of them for you as reference for the rest.

Explanation for #1

The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles

180 - (58 + 47) = 75

Missing angle is 75

Explanation for #4

A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.

Then take 180 <em>again </em>and subtract the answer you got from the first step.

180 - (21 + 34) = 125

180 - 125 = 55

The missing angle is 55

Alexa's non-taxable income will be equal to $603.3.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Alyssa started working making $14.75 per hour. She worked a total of 48 hours during the last pay cycle. Her taxes totalled $104.22.

The non-taxable income will be calculated as,

Total income = 14.75 x 48 = 707.52

Non-taxable income = 707.52 - 104.22

Non-taxable income = $603.3

Therefore, Alexa's non-taxable income will be equal to $603.3.
