Answer: If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the upper quadrants, then the reflection would be negative for x.

If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the lower quadrants, then the reflection would be negative for y.

This is because the lower quadrants are usually negative and the upper quadrants are usually positive according to the x axis. The same thing vice verse with y.

These are the rules that I’m guessing your trying to find. Hope this helps!

The sound intensity of rustling leaves is 100 times the reference intensity. Use your graph to determine the sound intensity of
wariber [46]

The sound intensity of rustling leaves,  y = 20 decibels

<u>Step-by-step explanation:</u>

y = 10logx

The sound intensity of rustling leaves is 100 times the reference intensity.

x = ratio of intensity of sound to reference to intensity

x = 100:1 or x = 100

y = 10 log(100) = 10 * 2 = 20 decibels

y = 20 decibels

I need blank 1 and blank 2
lord [1]

Answer:

Blank 1: 40

Blank 2: 10

Step-by-step explanation:

You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.

y+x=50

y-x=30

Adding these two equations together, you get:

2y=80

y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.

40-x=30

x=10

Hope this helps!

Division Problem: 90 people were invited to the party.

1. How many tables are needed, if each table can seat 8 people?

2. How many tables will be completely full?

3. How many people will be at an incomplete table?

Solution:

You have that 90=8·11+2 (8 - divisor, 11 - quotient, 2 - remainder).

Since the quotient is 11, 12 tables are needed, 11 tables will be completely full and the last 12th table will be incomplete, only 2 people will be at this table.

Answer: 1. 12 tables, 2. 11 tables, 3. 2 people

If man's salary is 20 dollors a week and he spends 14 dollors a week how long will it take him to save 300 dollors
Contact [7]
Solutions 

⇒ Given 

Salary - $ 20 

Spends - $ 14 

The first step is to subtract 14 from 20. When we do this, we will know how much he saves.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ 

Calculations 

20 - 14 = 6 

He saves $ 6 each week. 

Now we have to find how many times 6 goes into 300. To do this we have to divide. 

300 ÷ 6 = 50 

<span>It is going to take him 50 weeks. </span>
