After translating sentence in to inequality we get x > 7*y.
Let us suppose two variables are x and y.
First let's understand what inequality means?
Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal symbol ≠" to indicate that two values are not equal. But various inequalities are used to compare the values and determine whether they are less than or greater than.

135 is 0.9% of what?
Answer: 15000
Step-by-step explanation: Step by step solution for calculating 135 is 0.9 percent of what number
We already have our first value of 135 and the second value of 0.9. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 1135 = 0.9% × Y
STEP 2135 =
0.9
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 0.9 we will arrive at:
STEP 3Y = 135 ×
100
0.9
STEP 4Y = 135 × 100 ÷ 0.9
STEP 5Y = 15000
Finally, we have found the value of Y which is 15000 and that is our answer.
You can easily calculate 135 is 0.9 percent of what number by using any regular calculator, simply enter 135 × 100 ÷ 0.9 and you will get your answer which is 15000

keeping in mind that water has no broth in it, so 0% of broth, let's plug in those percentages in decimal format to see how much each one has.
what's 80% of "x"? well (8/100) * x = 0.80x.

consider the process of throwing $m$ balls into $n$ bins, where each ball is thrown into a uniformly random bin, independent of other balls. what is the expected number of balls in a particular bin $b$?
The predicted quantity of balls in the first bin is (1/n)n.
Considering that,
There are the same number of balls and containers.
If so, then each container must always contain one ball. The probability of each ball landing in the first bin is (1/n)n.
For instance -
Three balls and three bins should be present. Next to each ball, place an A, B, and C. There are numbers 1, 2, and 3 on the containers. Ball A has a 1/3 chance of landing in bin 1. Although there is a 1/3 probability that ball B will drop in bin 1 and a 1/3 chance that ball C will do the same, both outcomes are possible. Therefore, bin 1 should be equal to 1/3 + 1/3 + 1/3. The rationale behind the projected values of bins 2 and 3 is identical.
According to the same logic, bins 2 and 3 should also have expected values of 1.
How probable is it that the first bin will receive all three balls?
In general, (1/n)n, which equals (1/3)3, or 1/3 x 1/3 x 1/3, equals 1/27.
Therefore, (1/n)n would be the expected number of balls in the first bin.

At 11:00 am, a body was found within a closed room of a mansion where the air temperature is a constant 70 degrees F. At the time of discovery, the core temperature was determined to be 85 degree F. One hour later, a second measurement showed the core temperature of the body was 80 degrees F. Assume the core temperature of the body at the time of death was 98.6 degrees F. Use Newton’s Law of Cooling to determine the time of death. Hint: Let t=0 represent 11:00 am and work backwards to 98.6 degrees F.
The time that has elapsed before the body was found is 1.5 hour
What is Newton's method of cooling ?Newton's law of cooling states that the rate of heat loss from a body is inversely related to the temperature difference between the body and its surroundings.
Given:
when time, t = 0, temperature = 98.6 ⁰F
when time, t = 1, temperature = 75⁰
when time, t = t, temperature = 80⁰
By Newton's method of cooling equation;
T(t) = [tex]T_s (T_0 - T_s)e^{kt[/tex]
T(t) = 70+ 28.6[tex]e^{kt[/tex]
Now, At the time of discovery
80 = 70+ 28.6[tex]e^{kt[/tex]
10= 28.6[tex]e^{kt[/tex]
Then, 1 hour later( t + 1) we have the second equation;
75= 70 + 28.6[tex]e^{kt[/tex]
28.6[tex]e^{kt[/tex] = 5
Now, divide equation 1 by equation 2;
2= [tex]e^{-k[/tex]
k = -0.693
The time when he dead body was discovered
10= 28.6[tex]e^{kt[/tex]
10= 28.6[tex]e^{-0.693[/tex]
-0.693t = ln (10 /28.6)
-0.693t = -1.05
t= 1.5 hour
Hence, the time that has elapsed before the body was found is 1.5 hour

Part a: 10z > 25,670; infinite integer.

Explain the term integer?All whole numbers including negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results. An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion. Integers include things like -5, 10, 21, 15, 18, 97, and 343.Part a: 10z > 25,670

M inverly proportional to g^3
M=24 when g=2. 5
a) find a formula for M in term of g
b) work out the value of g when M=1/9
The answers to both the subparts using the inversely proportional property are shown:
(A) The formula will be: M = 375/g³
(B) The value of g is 15 when M = 1/9.
What do we mean by inversely proportional?When one variable decline, the others also decline in the same ratio.
When two variables move in opposite directions, one variable reduces as another increase, and the other increases as another variable lower, the variables are said to be inversely proportional.
Since M and g3 have an inverse relationship, we can say:
M = k/g^3
Assuming that g = 2.5 and that M = 24 then:
24 = k/(2.5)^3
24*(2.5)^3 = k = 375
(A) Formula for M in terms of G:
The formula will be M = 375/g³.
(B) Value of G when M = 1/9:
If M = 1/9, we get:
1/9 = 375/g^3
g^3 = 9*375
g = ∛(9*375) = 15
Therefore, the value of g is 15 when M = 1/9.
Therefore, the answers to both the subparts using the inverse proportional property are shown:
(A) The formula will be: M = 375/g³
(B) The value of g is 15 when M = 1/9.

Using Pythagoras's theorem, the relationships of the sides of the right triangle is x² - 21x + 108 = 0.
The value of x in the right triangle is x = 9 or x = 12.
How to find the sides of a right angle triangle?The right angle triangle is a triangle with one of its angles as 90 degrees. The sides of a right angle triangle can be found using Pythagoras's theorem.
Hence,
c² = a² + b²
where
c = hypotenusea and b are the other legs.Therefore, the equation to show the relationships between the three sides can be gotten by applying Pythagoras's theorem.
x² + (21 - x)² = 15²
x² + (21 - x)(21 - x) = 225
x² + 441 - 21x - 21x + x² = 225
2x² - 42x + 441 - 225 = 0
2x² - 42x + 216 = 0
divide through by 2
x² - 21x + 108 = 0
Let's find the value of x by factoring.
x² - 21x + 108 = 0
x² - 12x - 9x + 108 = 0
x(x - 12) - 9(x - 12) = 0
(x - 9)(x - 12) = 0
Therefore,
