29.25 is what percent of 78
Answer:
2
Step-by-step explanation:
Answer:
thirty - eight percentage
Step-by-step explanation:
You are going to have to divide for this question.
29.25 / 78 = 0.375
0.375 ≈ 0.38
0.38 * 100 = 38
So 29.25 is 38% of 78.

Which number produces an irrational number when added to 1/3?
Answer:
B
Step-by-step explanation:
Since all other numbers are rational numbers, and with pi being irrational, adding 1/3 to 2pi would keep it irrational.
Answer:
2 pi
Step-by-step explanation:
So lets try and check , why to be lazy ?
1/3+2/3 =1 , as we all know 1 is a rational number.
.
so lets move to another option
Now ,
1/3+2 pi = 7/2 pi , its an irrational number .
we already got the answer , but we will try others too .
( Because i have so much amount of time , let me kill some of it! )
1/3+2 = 2.3333333.... which is again a ratiomal number .
1/3+0.166 = 0.49933333333... which is again a rational number .
Additional Information
An irrational number is a number that is nor terminating , nor recurring .The set of rational and irrational number is called real numbers .No rational number is irrational number , and no irrational number is rational number .Need ASAP worth 100 points
That's the Riemann Zeta function. Here s is a complex number. If you can prove that all the non-trivial zeros of ζ(s) (which includes its analytic continuation to the entire complex plane) are on the line Re(s) = -1/2 then you will become a famous mathematician. You didn't even ask a question; not a very auspicious start, but don't give up.
If we restrict s to the reals, as Euler first did, we can prove there are an infinity of primes. Ever since the Zeta function has been closely related to the prime numbers.
One fun fact is ζ(-1) = -1/12, which has spawned lots of bad math claiming the sum of the natural numbers is -1/12,
[tex]-\dfrac{1}{12} = \zeta(-1) = \dfrac{1}{1^{-1}} + \dfrac{1}{2^{-1}} + \dfrac{1}{3^{-1}} + ... = 1 + 2 + 3 + 4 + ...[/tex]

QUESTION 27 • 5 POINTS
Marco needs to mix a solution that is 8% iodine with one that is 44% iodine to obtain 200 liters of a solution that is 29%
iodine. Using a system of linear equations, find how many liters of the 8% iodine solution will be required to create the new
solution. Round to the nearest liter.
Answer:
83 liters
Step-by-step explanation:
If we call the amount of liters of the 8% iodine solution by x and the amount of liters of the 44% iodine solution by y, we can write the following equations:
x + y = 200
x*0.08 + y*0.44 = 200*0.29
From the first equation, we have that y = 200 - x
Using this value of y in the second equation, we have that:
0.08x + (200 - x)*0.44 = 58
0.08x + 88 - 0.44x = 58
0.36x = 30
x = 30/0.36 = 83.3333 liters
Rounding to nearest liter, we have x = 83 liters

Complete the table for the given rule.
Rule: y= 1/3x
Answer:
12 - 4
3 - 1
18 - 6
Step-by-step explanation:
This is simply a matter of pluggin in the method, so let's do it shall we?
It wants you to put the a third of each number, so you'll divide each number by three to get what the third is!
VISUAL REPRESENTATION:
12÷3 = 4
3÷3 = 1
18÷3 = 6
The completed table for the given rule y = (1/3)x is given.
To complete the table for the given rule y = (1/3)x, we need to substitute the values of x into the equation and calculate the corresponding values of y.
Using the given rule y = (1/3)x:
1. For x = 12:
y = (1/3) * 12 = 12/3 = 4.
2. For x = 3:
y = (1/3) * 3 = 3/3 = 1.
3. For x = 18:
y = (1/3) * 18 = 18/3 = 6.
Now, the completed table for the given rule is:
x | y
--------
12 | 4
3 | 1
18 | 6

The distance between City A and City B is 250 miles. A length of 1.7 feet represents this distance on a certain wall map. City C and City D are 3.74 feet apart on this map. What is the actual distance between City C and City D?
Step-by-step explanation:
You have to apply a proportion:
250 : 1.7 = x : 3.74
250 × 3.74 = 1.7 × X
X = 250×3.74 / 1.7 = 550
Answer:
549.78 miles
Step-by-step explanation:
250m / 1.7ft = ~147 miles/ft
147 * 3.74 = 549.78

4500 ≤ 1400 + .05x, where x = sales
800 + .15s = 5000, where s = sales <-- this isn't an inequality, because it's asking for the exact amount of sales Ling needs to get.
(85+76+94+81+y)/5 ≥ 85, where y = next test score
Answer:
5. at least $62,000 worth of cars
6. $28,000 on sales
7. at least an 89
Step-by-step explanation:
5. We have a base salary of $1400 and the earning is 5% on sales (in other words, of the total profits from sales, the salesperson gets 5% of that). If s represents sales, we can say that the salesperson earns:
1400 + 0.05 * s
We want the end product to be at least $4500, so:
1400 + 0.05s ≥ 4500
0.05s ≥ 3100
s ≥ $62,000
The salesperson needs to sell at least $62,000 worth of cars.
6. This is similar to the previous question. Say the number of sales is s. Then, we have:
800 + 15% * s = 5000
800 + 0.15s = 5000
0.15s = 4200
s = 28,000
Ling needs to sell $28,000 on sales.
7. Let's say the last score is x. The average is found by adding all the test scores and dividing by the number of tests:
(85 + 76 + 94 + 81 + x) / 5 ≥ 85
336 + x ≥ 425
x ≥ 89
Latrell needs to earn at least an 89 on his next test to keep his average at 85 or higher.

What interval includes all possible values of x, where -306 - 2x) > 4x + 12?
Corrected Question
What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x + 12?
A. (–∞, –3] (B) [–3, ∞) (C)(–∞, 15] (D)[15, ∞)
Answer:
(D)[15, ∞)
Step-by-step explanation:
We want to determine what interval of x includes all possible values of x in: [tex]-3(6 - 2x) \geq 4x + 12[/tex]
First, we open the bracket on the Left hand side
[tex]-18+6x \geq 4x + 12[/tex]
Next, we collect terms with x on the Left hand side and constants on the right hand side.
[tex]6x-4x \geq 12+18\\2x\geq 30\\$Divide both sides by 2\\x \geq 15[/tex]
Therefore, the interval of x which includes all possible values of x is [15, ∞).
Option D is the correct option.

Let's put all of these into percent form.
P(Guilty) = 0.25 = 25%
P(Innocent) = 55%
P(Retrial) = 1/5 = 0.2 = 20%
Next, we need to order them from least to most likely. The least likely event to occur would be the smallest percent, then the next smallest, etc.
Order: Retrial, Guilty, Innocent
Hope this helps! :)
Answer:
retrial, guilty, innocent
Step-by-step explanation:
We need to first convert these into the same kind of format, whether it's all decimals, all fractions, or all percentages. Let's just do decimals.
The guilty is already a decimal: 0.25.
The innocent is a percent. Remember that % simply means "out of 100", so 55% is 55/100. When we divide by 100, we move the decimal point two places to the left, so 55/100 = 0.55.
The retrial is a fraction. Just try to remember that 1/5 always equals 0.2.
The least likely event will be the smallest decimal, which is 0.2. The most likely event is the largest decimal, which is 0.55. So, the order is:
retrial, guilty, innocent
Garrett was given two numbers, 1.6 and 25, and was instructed by his teacher Mrs. Hellie to find
the sum. Garrett found the sum and stated that the answer was a rational number. Do you agree or
disagree with Garrett? Justify your answer.
Answer:
I agree with Garret.
Step-by-step explanation:
A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 26.6, and multiply the numerator and denominator by 10 if it is 1 number. Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:
266 / 10
Then, we need to divide the numerator and denominator by the greatest common divisor(GCD) to simplify the fraction.The GCD of 266 and 10 is 2. When we divide the numerator and denominator by 2, we get the following:
133 / 5, which is ni a p/q form.
What is the value of x:
5x + 4 = 2x +22
How would you solve this question?
Answer:
6
Step-by-step explanation:
1. Combine like terms (x)
Subtract 2 from one side to move it to the other side. *What you do to one side, you must do to the other.
You now have: 5x(-2x)+ 4= 22
Subtract 2 from 5= 3x
You now have 3x+ 4 = 22
*You can’t add 4 to 3x because they are different terms (can’t add whole numbers with an x value)
Subtract 4 to move it to the other side;
3x= 22-4
22-4 = 18
3x=18
Divide by 3 to remove 3 from one side
X= 6 (because 18/3= 6
Answer: x = 6
Explanation: This problem can be done either of two ways by putting the variables together on the left and the numbers together on the right or vice versa.
If we put our variables together on the left and our numbers together on the right, we would start by subtracting
2x from both sides to get 3x + 4 = 22.
Next, we subtract 4 from both sides to get 3x = 18.
Finally, we divide both sides by 3 to get x = 6.
Note that we can check our answer by plugging 6 back in
for both of the x's in the original equation.
So go ahead and check the answer and see if it works.
