Answer:
Induction is done by demonstrating that if the condition is true for some n then it must also be true for n+1. If you then show that the condition is true for n=0 then it must be true for all n>0. For this problem:
Step 1: n=1
The sum of the first 1 odd numbers is 1. 12=1. Therefore the condition holds for n=1.
Step 2: induction
If the sum of the first n odd numbers is n2 then the sum of the first n+1 integers is n2+(2n+1)=(n+1)(n+1)=(n+1)2
So the condition is also true for n+1.
Step 3: conclusion
Since the we have shown that the condition is true for n=1 and we have shown that if it is true for n then it is also true for n+1 then it follows by induction that it is true for all n≥1.

Answer:
It's 90%
Step-by-step explanation:
90% of 60
= 0.9 * 60
= 540
Hope it helps. :)
Answer:
90%
Step-by-step explanation:
Let's set the missing blank value to x. (x% of 600 = 540)
In order to find a percentage of anything, we simply just divide by 100, and then multiply that value to the value we want to find the percentage of. Thus our new equation can be rearranged to this:
0.01x (600) = 540
Now simplify:
6x = 540.
x = 90.
That means 90% of 600 is 540.

Soup A has 5 grams of sodium in every 12 cups. Soup B has 8 grams of sodium in every 13 cups. Which soup has more sodium per cup?
Answer:
Soup B has more sodium per cup.
Step-by-step explanation:
If we're doing sodium per cup, then we have to divide 5 by 12, and 8 by 13.
5÷12=~0.4 grams
8÷13=~0.6 grams
0.6>0.4
So B has more sodium per cup.
Which of the following is a step in simplifying the expression x multiplied by y to the power of 3 over x to the power of negative 4 multiplied by y to the power of 4, the whole to the power of negative 2.?
x to the power of negative 2 multiplied by y to the power of negative 6, the whole over x to the power of 8 multiplied by y to the power of negative 8.
x to the power of negative 2 multiplied by y, the whole over x to the power of negative 6 multiplied by y to the power of 2.
x to the power of negative 2 multiplied by y to the power of negative 6, the whole over x to the power of negative 4 multiplied by y to the power of 4.
x to the power of negative 2 multiplied by y, the whole over x to the power of negative 4 multiplied by y to the power of 4.

Step-by-step explanation:
Answer:
True.
Step-by-step explanation:
3/4+(−3/8)+(−1/4)=(−3/8)+3/4+(−1/4)=−3/8+[3/4+(−1/4)]
= 6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[6/8-2/8]
= 6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[4/8]
=6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[4/8]

In a northwestern U.S. town, the peak temperature is 96° Fahrenheit in August. After the peak, it drops an average of 4° Fahrenheit per week. The graph below models the number of weeks it would take the temperature to drop below freezing, 32° Fahrenheit.
okay so they show a pic of a number line from 10-22 and the 16 number has a ray with a open circle!?
Which of the following is the correct interpretation of the solution?
A. It would take more than 16 weeks to drop below freezing.
B. It would take 16 or less weeks to drop below freezing.
C. It would take less than 16 weeks to drop below freezing.
D. It would take 16 or more weeks to drop below freezing.
Answer:It would take more than 16 weeks to drop below freezing.
The temperature is dropping from 96°F to 32°F at a rate of 4°F per week, where 32°F is the freezing point.
Hence, 32 = 96 - 4w { Where w week is required to reach 32°F }
⇒ 4w = 64
⇒ w = 16
Therefore, it would take more than 16 weeks to drop below freezing. ( Answer )

Which number line shows 1 to 4 divided into thirds?
Answer:
Line 1.
Step-by-step explanation:
This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:
1/3 2/3 3/3
This is split into thirds
The required number line that represents the dividend of the three is the fourth line. Option D is correct.
Given that.
To determine the line that has a dividend of 3.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3
Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.

Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100. City carpets charges $25 per square yard for the same carpeting and an additional installation fee of $70. Write and solve an equation to find the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
Answer:
10
Step-by-step explanation:
country carpets: y = 22x + 100
City carpets: y = 25x + 70
22x + 100 = 25x + 70
I could be wrong but I hope this helps!
Answer:
10 square yards
Step-by-step explanation:
25x+70= t
22x+100= t
25*10= 250+70= 320
22*10=220+100= 320

How should the decimal point in 0.937 change to get the correct answer to 0.937 ÷ 10²?
A. move it 2 place to the right
B . move it 2 places to the left
C .move it 3 places to the right
D .move it 3 places to the left
Answer:
B.
Step-by-step explanation:
When moving a decimal point 2 places to the right you are multiplying. When moving it to the left you are dividing. In this case we are moving 2 places to the left which the exponent 2 is representing. If you were to move 3 places to the right or left you would need to have a three as your exponent.
