1/3log125/8-2log2/5+log80/125
Answer:
1
Step-by-step explanation:
⅓Log₁₀(125/8) – 2Log₁₀(2/5) + Log₁₀(80/125)
The above expression can be simplified as follow:
⅓Log(125/8) – 2Log(2/5) + Log(80/125)
Recall:
a LogM = Log Mᵃ
Therefore,
⅓Log(125/8) – 2Log(2/5) + Log(80/125)
= Log(125/8)¹/³ – Log(2/5)² + Log(80/125)
= Log(5/2) – Log(4/25) + Log(16/25)
Recall:
Log M – Log N = Log M/N
Log(5/2) – Log(4/25) = Log (5/2 ÷ 4/25)
Log(5/2) – Log(4/25) = Log (5/2 × 25/4)
Log(5/2) – Log(4/25) = Log (125/8)
Therefore,
Log(5/2) – Log(4/25) + Log(16/25)
= Log (125/8) + Log(16/25)
Recall:
Log M + Log N = Log MN
Log (125/8) + Log(16/25)
= Log (125/8 × 16/25)
= Log 10
= Log₁₀10 = 1
Therefore,
⅓Log(125/8) – 2Log(2/5) + Log(80/125)
= 1

Answer:
75
Step-by-step explanation:
Use the slope formula (rise/run):
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
(375 - 150)/(5-2) = 225/3 = 75

Question 4

At noon, a barista notices that she has $30 in her tip jar. If she makes an average of $0.45
from each customer, how much will she have in her tip jar if she serves n customers during
her shift?
(equation)
How much will she make if she serves 134 customers?
How many customers did she serve by noon?
Answer:
a [tex]A = 30 + 0.45 n[/tex]
b [tex]A = 90.3[/tex]
c 0 customers
Step-by-step explanation:
Given
[tex]Base\ Amount = 30[/tex]
[tex]Rate = 0.45[/tex] per customer
Solving (a): Amount (A) on n customers
This is calculated as:
[tex]A = Base\ Amount + Rate * n[/tex]
[tex]A = 30 + 0.45 * n[/tex]
[tex]A = 30 + 0.45 n[/tex]
Solving (b): Amount on 134 customers
In this case: n = 134
So:
[tex]A = 30 + 0.45 * 134[/tex]
[tex]A = 30 + 60.3[/tex]
[tex]A = 90.3[/tex]
Solving (c): Customers at noon.
At noon, the amount is 30.
So:
[tex]A = 30 + 0.45 n[/tex]
[tex]30 = 30 + 0.45n[/tex]
Collect like terms
[tex]0.45n = 30 - 30[/tex]
[tex]0.45n =0[/tex]
[tex]n = 0[/tex]
40% of the trees are 300 trees. How many trees are 20%?
Answer:
150 trees
Step-by-step explanation:
If 40% of the trees is 300, you'd expect that 20% (half the percentage) is also half the trees.
Answer:
150 trees
Step-by-step explanation:
40 % / 2 = 20%
300 / 2 = 150 trees

what is X please help 5x - 13.75 = 20
Answer:
X= 1.25
13.75 + 5= 18.75
20 - 18.75= 1.25 OR 1.25 + 18.75 = 20
Step-by-step explanation:
Solve for x.
5
10
12
13
Answer: B) 4 & 1/6
Nice work on getting the correct answer.
============================================================
Explanation:
x is opposite the marked acute angle
5 is opposite the corresponding acute angle
So x and 5 are proportional to each other. We can form the ratio x/5
Similarly, 10 and 12 are proportional to one another. We can form the ratio 10/12.
Set those ratios equal to each other and solve for x
x/5 = 10/12
12x = 5*10 ... cross multiply
12x = 50
x = 50/12 ...... divide both sides by 12
x = (25*2)/(6*2)
x = 25/6
x = (24+1)/6
x = 24/6 + 1/6
x = 4 + 1/6
x = 4 & 1/6 which shows why choice B is the answer.
Side note: 25/6 = 4.167 approximately

This is a math riddle for pi day I can’t understand. There was one with the pi symbol in a pumpkin so it was obviously pumpkin pie, so what would this one be? Any ideas?
Answer:
This is the math riddle for pi..
Step-by-step explanation:
They mean by this question, What do you get if you divide the circumference of a pumpkin pie by its diameter?
Pi is the ratio of circumference and the diameter. and people want to understand why pi =3.14. ... very long explanation. This will be college level to understand these math.
We don’t really need the diagram at this stage of course.
The internal angle is 180o−360o / 24=180o−15o =1 65o . Half of this is 82.5o . The perimeter is now 24x so we have:
24 x /h = 24 / tan(82.5o) Rather remarkably:
So tan(82.5o) =√+2 + √+3+√+4+√+6
24 x / h = 24 / ( √+2 + √+3+√+4+√+6 ≈3 .1596599421

You know the two legs of a right triangle. You also know the measure of one of the acute angles of the triangle. Could you use the given law or theorem to find the length of the hypotenuse? Select Yes or No for A-C.
A. Law of Sines (YES OR NO )
B. Law of Cosines (YES OR NO )
C. Pythagorean Theorem (YES OR NO )
Answer:
A (NO) B(YES) C(YES)
Step-by-step explanation:
Law of sines is used to find the measurements of angles not sides. Law of cosines is used for the sides. And pythagorean theorum should be obvious as it is based on the sides of a right triangle.
Juan spent 1 1/2 hours working on a project on Monday, 2 hours on Tuesday, and 2 3/4 hours on Thursday. How many hours did it take him to finish the project?
Answer:
Monday hours + Thursday hours = Total hours
1 1/2 + 2 3/4 = 3 + (? how do you add 1/2+3/4)
Now, you could convert to all improper fractions:
3/2 + 11/4
6/4 + 11/4 [4 is the Least Common Multiple of 2 and 4]
17/4
4 1/4 [then back to mixed numbers]
Or. you could add 1+2=3
and 1/2 + 3/4
2/4 + 3/4
5/4
1 1/4 [convert to mixed number]
3 + 1 1/4 = 4 1/4 [remember to add the 3]

marbles numbered from 1 to 12 are put in a bag. if marbles are not put back into the bag after being drawn, what is the probability of drawing two prime numbers in a row?
Answer:
[tex]Probability = \frac{1}{11}[/tex]
Step-by-step explanation:
Given
Marbles = 12
Selection without replacement
Required
Determine the probability of selecting 2 primes
Between 1 and 12, the prime digits is 4, and they are: 3, 5, 7 and 11
So, when the first marble is picked, the probability that it will be prime is:
[tex]P(First) = \frac{4}{12}[/tex]
Now there are 3 primes left and 11 marbles in total. So, the probability of selecting another prime is:
[tex]P(Second) = \frac{3}{11}[/tex]
The required probability is:
[tex]Probability = P(First) * P(Second)[/tex]
[tex]Probability = \frac{4}{12} * \frac{3}{11}[/tex]
[tex]Probability = \frac{1}{11}[/tex]
