Answer:
7.7 %
Step-by-step explanation:
352-325
=27
27/352 x 100/1
7.670
=7.7%
Answer: 7.7%
Step-by-step explanation:
1. 352 - 325 = 27. This is how many students left.
2. x/100 = 27/352 is the equation.
3. Solve for x: 2700/352 = x = 7.6704
This rounded to the nearest tenth is 7.7%
Which of the following shows the extraneous solution to the logarithmic equation log7(3x^3+x)-log7(x)=2?
Answer:
x=4
Step-by-step explanation:
on edge
The extraneous solution to the logarithmic equation log₇(3x²+x)-log₇x=2 is x=16
What is logarithm?When you raise a number with an exponent, there comes a result.
Lets say you get[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
We are given the function as;
log₇(3x²+x)-log₇x=2
Domian: 3x²+x>0
x(3x+1)>0
x∈(-∞,-1/3)U(0,∞)
Hence, x∈(0,∞), Thus x∈(0,∞)
In this problem we use the following formula:
[tex]\boxed {log_ax-log_ay=log_a\frac{x}{y}}\displaystyle\\log_7(3x^2+x)-log_7x=2\\\\log_7(x(3x+1))-log_7x=2(1)\\\\log\frac{x(3x+1)}{x} =2(log_77)\\\\log(3x+1)=log_77^2\\\\log_7(3x+1)=log_749\\\\\\\\3x+1=49\\\\3x+1-1=49-1\\\\3x=48\\\\x=16[/tex]

1. Is the product of 12 and 3/4 more or less than 12? Explain your answer in complete sentences.
2. Is the quotient of 5 and 1/2 greater than or less than 5? Explain your answer in complete sentences.
Answer:
1.) The product of 12 and 3/4 is less than 12. This is because you are multiplying 12 by a number less than 1.
2.) The product of 5 and 1/2 is less than 5, this is because you are multiplying 5 by a number less than one.
Step-by-step explanation:
If multiplied by a number less than one then it will be smaller than original
If multiplied by one will be the same as original
If multiplied by a number greater than one it will be greater than original

how many powers with an exponent of 2 are there between 1 and 100?
There are 10 perfect squares between 1 and 100, and 10 powers with an exponent of 2 between 1 and 100.
What is Number system?A number system is defined as a system of writing to express numbers.
Between 1 and 100, the perfect squares (numbers that can be expressed as the square of an integer) have exponents of 2.
We need to count the number of perfect squares between 1 and 100. These include:
1² = 1
2² = 4
3²= 9
4² = 16
5² = 25
6² = 36
7²= 49
8² = 64
9² = 81
10² = 100
So, there are 10 perfect squares between 1 and 100, and therefore 10 powers with an exponent of 2 between 1 and 100.

Answer:
Step-by-step explanation:
7) The tangent angles are 90° each.
The angles of a quadrilateral add up to 360°, so ? = 360°-90°-90°-73° = 107°.
8) Solve this the same way as question 7). ? = 360°-90°-90°-57° = 123°.
Questions 9) and 10) are cut off, so I assume you don't need to know those.

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
live to be 80 years old and sleep 8 hours a day, How many years have I slept
Solution
A day has 24 hours
24 = 8 + 8 + 8
So you spent 1/3 of your time sleeping.
You can get the same answer if you do 8/24
8/24 = (8 ÷ 8) / ( 24 ÷ 8) = 1/3
All you need to do now is to find 1/3 of 80
1/3 of 80 = 1/3 × 80 = 80/3
80 / 3 = (78 + 2) / 3 = 78 / 3 + 2 / 3 = 26 + 2/3
So that is 26 years + ( 2/3 of a year)
What is 2 / 3 of a year?
Since 2 /3 of a year is a fraction of a year, the answer for 2 / 3 of a year will be in months.
1 year = 12 months.
Just find out what 2/3 of 12 is
2/3 of 12 is 2/3 times 12
2/3 times 12 = (2 times 12) / 3 = 24 / 3 = 8 months
Putting everything together, you slept for 26 years and 8 months during your lifetime.
Hope it helped!

a rectangular picture with a perimeter of 27 cm is glued in the center of a rectangular piece of cardboard. there is a 1 cm margin (of empty cardboard) all around the picture. what is the perimeter of the peice of cardboard
Answer:
31 cm
Step-by-step explanation:
A rectangle has 4 sides.
27 cm + 4 cm = 31 cm.
The perimeter is 31 cm.
If you are confused, to find perimeter you add all the sides up. That is why I added 1 + 1 + 1 + 1 / 4.
For inches or a different measure I recommend just converting it. You never mentioned the measure so I decided with cm.
