PLEASE HELP THIS IS A QUESTION OF LIFE OR DEATHWhich statement correctly identifies the line of reflection?

Answers

Answer 1

Answer:

Answer:

The third option is the correct answer.

Step-by-step explanation:

The triangles are reflected across the line y = x

When a triangle is reflected across the line y = x, this means that the x-coordinate and y-coordinate have changed their places. We must know that each point of a reflected image and the original image are at the same distance from the the line of reflection.

Answer 2

Answer: C because the x-axis and the y-axis are switched, basically.

Find 6% of $5900000 to the nearest cent

Answers

Answer:

$354,000

Step-by-step explanation:

Since six percent in decimal is .06, all we have to do is multiply that by 5900000. When multiplied this would leave our answer to be $354,000. This is the answer unless we're missing any decimals, that would relate to the part of the question where it says round to the nearest cent.

Emmanuel wants to tile his rectangular floor. he has two kinds of tiles to choose from, one of which is larger than the other. emmanuel hired your services to help him decide which tile to use.a.what area will be covered by 7"x7" tile? 21"x21" tilwe
b.if the rectangular floor has dimension of 420" by 630"
c.how many big square tiles are needed to cove rthe rectangular floor?
d.if each small tile costs P15.00 and each big tile costs P60.00which which tile should emmanuel use to econimize in tiling his floor? why?

Answers

a).
The 8" by 7" tile covers 49 square inches.
The 21" by 21" tile covers 441 square inches.

b).
The area of the floor is (420" x 630") = 264,600 square inches.

c).
It would take (264,600) / (441) = 600 large tiles to cover the floor.

d).
Emmanuel should use the big tiles to cover his floor.
-- A big tile costs 4 times as much as a small tile, but it has 9 times
as much area as a little tile has, so it is a better buy.
-- Plus, he would have to pay the floorman a lot more to glue down 5,400 tiles
than he will have to pay to glue down only 600 tiles.
-- Since he has hired my services to advise him, I will charge him only 15%
of the difference if he takes my advice, so he will still be money ahead.

Describe and correct the error(s) made in each of the problems below. 1−x / (5−x)(−x)=x−1 / x(x−5)

5/s+2/5=2/s

Answers

Answer:

$\displaystyle (1-x)/((5-x)(-x)) =-(x-1 )/( x(x-5))$

$\displaystyle (5)/(s)* (2)/(5) =(2)/(s)$

Step-by-step explanation:

Errors in Algebraic Operations

It's usual that students make mistakes when misunderstanding the application of algebra's basic rules. Here we have two of them

When we change the signs of all the terms of a polynomial, the expression must be preceded by a negative sign
When multiplying negative and positive quantities, if the number of negatives is odd, the result is negative. If the number of negatives is even, the result is positive.
Not to confuse product of fractions with the sum of fractions. Rules are quite different

The first expression is

$1-x / (5-x)(-x)=x-1 / x(x-5)$

Let's arrange into format:

$\displaystyle (1-x)/((5-x)(-x)) =(x-1 )/( x(x-5))$

We can clearly see in all of the factors in the expression the signs were changed correctly, but the result should have been preceeded with a negative sign, because it makes 3 (odd number) negatives, resulting in a negative expression. The correct form is

$\displaystyle (1-x)/((5-x)(-x)) =-(x-1 )/( x(x-5))$

Now for the second expression

$5/s+2/5=2/s$

Let's arrange into format

$\displaystyle (5)/(s)+(2)/(5) =(2)/(s)$

It's a clear mistake because it was asssumed a product of fractions instead of a SUM of fractions. If the result was correct, then the expression should have been

$\displaystyle (5)/(s)* (2)/(5) =(2)/(s)$
