Step-by-step explanation:
A package of screen protectors for an iPhone
are priced $12.99. What is the price of the screen
protectors after 6% sales tax?
Answer: $13.77
Step-by-step explanation:
To get the final price for the screen protectors, we have to calculate the value of the tax and add to the current price of the screen protector.
The sales tax will be:
= 6% × $12.99
= 6/100 × $12.99
= 0.06 × $12.99
= $0.7794
The price of the screen protector will now be:
= $12.99 + $0.7794
= $13.7694
= $13.77
Suppose a city with population 600,000 has been growing at a rate of 3% per year. If this rate continues, find the population of this city in 22 years.
Answer:
The answer should be around 1,149663 (Rounded off to the nearest whole number. Also if a population has a remainer you usually add it as 1. This is because these are people)
Step-by-step explanation:
First step involves listing the formulas being used:
600,000= population, 0.03= growth rate 22years= period
Therefore, we take the 600,000 and multiply by 1+0.03 ^22(to the power of 22 or period)
So, 600,000(1+0.03)^22
=1,149662.045 /1,149663

Two polygons are congruent if and only if there exists a composition of __ that maps one polygon to the other polygon.
Answer:
two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.
(instead of translations/rotations we could write transformations, but there are transformations that also change the size of the figure, so I think that writing translations/rotations is more precise)
Step-by-step explanation:
Two figures are congruent if they have the same shape and size.
So for example, if we have one triangle, and we reflect that triangle along some line, those bot images will have the same shape and size (but maybe different orientations) so the triangles are still congruent.
Also, we could translate the image, or simply rotate it along some point, and the resulting image will be congruent to the initial image.
Then two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.
The composition that maps one polygon to the other polygon to make both congruent is called; Similarity transformation.
In transformations in mathematics, it could involve dilation, translation, rotation e.t.cNow, we are told that there has to be a composition that will map one polygon to another one. This means that the two polygons must have the same shape after transformation.
The only method of transformation that can achieve mapping of one polygon to another is called similarity transformation.Read more about Similarity transformations at;

A triangle has one leg that is 8, one leg that is 15 and a hypotenuse that is 20. Is it a right triangle?
Answer:
No
Step-by-step explanation:
A^2+b^2=c^2
8^2+15^2=20^2
64+225=400
289=400
289 does not equal 400 so it is not a right triangle

Answer:triangles always equal 180 so subtract the variable inside the triangle.
Step-by-step explanation:
How do you get 4y-4x=16 into slope intercept form simplifying all fractions?
Solve for x. Round your answer to the nearest tenth

16
The variable x is the hypotenuse, and the value of x in the right triangle is 24.8
How to determine the value of x?The complete question is a right triangle, where x is the hypotenuse.
So, the equation of x is:
[tex]x^2 = 19^2 + 16^2[/tex]
Evaluate the sum of exponents
[tex]x^2 = 617[/tex]
Take the square root of both sides
x = 24.8
Hence, the value of x is 24.8

Truefind the area of the shaded portion pls
Answer:91
Step-by-step explanation:
Take the area of the large square - 10*10 =100
Then subtract the area of the white square - 3*3 = 9
So 100-9 =91 units^2
Answer:
91 [tex]units^2[/tex]
Step-by-step explanation:
To do this you have to find the area of the total square using A=bh
So, A= (10)(10)
A=100
then find the area of the unshaded square using the same formula
A=(3)(3)
A=9
Then, subtract 100-9=91
So, your answer for the shaded square is 91 [tex]units^2[/tex]
