Answer:
option b
Step-by-step explanation:
413 is the same as a number decreased by 11 because when you say 11 is decreased by a number that means we are subtracting a number from 11 but when you say a number is decreased by 11 it means 11 is being subtracted from a certain number to give 413

Answer the question below
Answer:
72%
Step-by-step explanation:
1. 53 - 30 = 23 ( under 35 years old plan to go hiking)
2. 23 + 9 = 32 (under 35 years old Total)
3. 83 - 32 = 51 ( 35 years old or over Total)
4. 51 - 30 = 21 ( 35 years old or over Do not plan to go hiking)
5. Total visitors under 35 years old = 32
visitors under 35 years old plan to go on hiking = 23
percentage = (23/32)*100 = 71.8 = 72% approx
the total is given by the addition of the people less than 35 years and those greater than 35 years so:
QUESTION 1:
x+30=53
x=53-30
x=23
QUESTION 2:
9+x=30
x=30-9
x=21
QUESTION 3:we found that the first number was 23 and to find the total we add it with 9:
23+9=32
QUESTION 4:we found that the second number was 21 and to find the total we add it with 30:
21+30=51
PROOF:when we add the totals of the the people less than 35 years and the people greater than 35 years (which we hot from adding the number in the 3rd and 4th illustrations). If our answers are correct it must give us 83,so let add:
32+51=83
IT GAVE US 83 SO OUR ANSWERS ARE CORRECT
and finally to find the percentage we have 53 as the total so:
(23/32)×100%
0.7187×100%
71.87%
and when we round it it gives us 72%
SO OUR FINAL ANSWER IS 72%

Ellen is excited to learn how to ski. She went to White Peaks Mountain, rented a pair of skis for $45, and took 4 hours of group skiing lessons. Ellen paid $165 in all.
Which equation can you use to find how much White Peaks charges, h, for each hour of group skiing lessons?
Answer:
x=30h
Step-by-step explanation:
First, you need to figure out how much she actually paid for lessons, so you need to subtract 45 from 165.
165-45=120
Now you know she paid 120 dollars in total for lessons.
You know she took four hours of lessons, so you divide 120 by 4.
120/4=30
It takes $30 an hour for lessons.
Now you can form an equation.
Since you know it takes $30 per hour of lessons, it will be 30h.
x is the full amount of money paid
You don't need to add 165-45 to your equation because not everyone will need to rent skis when they come to White Peaks.
Hope this helps!
x=30h is the equation used to find how much White Peaks charges, h, for each hour of group skiing lessons.
What is a fixed charge?A fixed charge is any type of expense that recurs on a regular basis, regardless of the volume of business.
First, we need to find out how much she actually paid for lessons, so we need to subtract 45 from 165.
165-45=120
Now we know that she paid 120 dollars in total for lessons.
Given that she took four hours of lessons, divide 120 by 4 to get the fixed charge of a lesson.
120/4=30
It takes $30 an hour for lessons.
Now we can form an equation.
Since it takes $30 per hour of lessons, it will be 30h.
x is the full amount of money paid.
No need to add 165-45 to equation because not everyone will need to rent skis when they come to White Peaks.
Hence, the equation formed to find the cost of each ession is x=30h

In Grand Forks, North Dakota, the temperature on Tuesday at 7pm was
¾ the temperature recorded in Fairbanks, Alaska at that same moment in time.
What is the temperature in Grand Forks, North Dakota?
Answer:
-19.8
Step-by-step explanation:
In Fairbanks , at noon -18
it decreased with 1.2 per hour for the next 7 hours .
so in total it decreased by 1.2 x 7 = 8.4
so at 7 pm it was -18-8.4 = -26.4
In Grand Forks at 7 pm 3/4 of -26.4 = -19.8

Answer:
81=5+b, 81-5=b, 81-b=5
Step-by-step explanation:
We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...
5+b=81 OR 81=5+b (transitive property)
Now, let's write the equation in terms of b.
5+b=81
Subtract 5 from both sides (subtraction property of equality)
5-5+b=81-5
b=81-5 OR 81-5=b (transitive property)
Lastly, let's write the equation in terms of 5.
5+b=81
Subtract b from both sides (subtraction property of equality)
5+b-b=81-b
5=81-b OR 81-b=5 (transitive property.

Replace the word "product" with a symbol for division.
Replace the word "product" with a symbol for multiplication
Replace the words "a number" with a variable to represent an unknown value.
Replace "twelve" with 12
The correct equation is n = 12 = 72.
The correct equation is 12n = 72.
The product of a number and twelve is seventy-two.
So, the product of x and 12 is 72

It will take 5 years for a person to have 10100 dollars.
What is Compound Interest ?Compound interest is calculated on the principal as well as the interest accumulated over the preceding period. It differs from simple interest in that interest is not added to the principal when calculating interest for the following month.
Given:
A person invest 7500 dollars in a bank.
The bank pays 6 interest compounded semi-annually.
The compound interest formula is equal to
A = P([tex]1+ r/n)^{n/t[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
So, substituting the values we get
10,100 = 7500 (1 + 0.06/2[tex])^{2t[/tex]
1.3466 = (1.03[tex])^{2t[/tex]
Taking log on both side we get
log (1.3466) = 2t log (1.03)
2t = log ( 1.3466- 1.03)
2t =0.12923 / 0.01283
t = 10.072 / 2
t = 5. 036 year

Joni bought 35 books at a price of Rp. 122,500. Toni bought the same 24 books as that Joni bought. How much did Toni pay for the book?
Answer:
Rs.84,000Step-by-step explanation:
Given,
Cost of 35 books Joni bought = Rs. 122,500
So,
Cost of 1 book = [tex]\frac{Rs. 122,500}{35}[/tex]
Now,
Same no. of books that Toni bought = 24
