The inequality describes the problem of a local ice cream shop has a parking lot with enough space for 18 cars is x + 7 ≤ 18
What is an Inequality?In mathematics, an inequality describes a relationship between two values of an algebraic expression that are not equal. “If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then, this relationship is called an inequality." For example, x>8 (x should be greater than 8).
We have, a local ice-cream shop has a parking lot with enough space.
The maximum number of cars will be parked in parking lot = 18.
At right now, the number of cars in parking lot= 7. Let assume that x be number of more cars can park in the lot. We have to express this in form of an Inequality. Total cars in parking lot = 7 + x but this number of cars cannot exceed the 18 , so x + 7 ≤ 18
Hence, required Inequality is x + 7 ≤ 18.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 18)(0,18) and (3, 6174)(3,6174).
The exponential function in the form y = ab^x is y = 18(7)^x
How to determine the exponential function in the formFrom the question, we have the following parameters that can be used in our computation:
Points: (0, 18) and (3,6174).
The above can be represented as
(x, y) = (0, 18) and (3,6174).
An exponential function is represented as
y = ab^x
Where
a = y when x = 0
This means that
a = 18
So, we have
y = 18b^x
At (3,6174), we have
6174 = 18b^3
So, we have
343 = b^3
Take the cube root of both sides
b = 7
This means that
y = 18(7)^x
Hence, the function is y = 18(7)^x

What is an Isosceles Triangle?An isosceles triangle is a type of triangle that has two sides that are of the same length, while the third side has a different length.
What is the Hypotenuse of a Triangle?The hypotenuse is found in a triangle that has a right angle. This means the triangle is a right triangle, and therefore, according to the Pythagorean theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the other legs of the triangle.
Considering the definition given above, it means the right triangle we are looking for must be a right triangle is isosceles, which hast two equal sides and an hypotenuse that is 8 units long.
The values of the set of lengths, 2, 4, and 8 cannot be the isosceles triangle because they have three different side lengths.
8,8, and 16 do not conform to the Pythagorean Theorem because:
16² ≠ 8² + 8²
4√2, 4√2, and 8 conform to the Pythagorean Theorem because:
8² = (4√2)² + (4√2)²

[tex]P=2L+2W[/tex]
This is the equation to find the perimeter of a rectangle.
We are given the perimeter which is 42.
We are also given that the length is the sum of twice its width and 3.
So we can write
[tex]42=2L+2W\\L=2W+3[/tex]
Lets solve using substitution.
Substitute [tex]L=2W+3[/tex] into the first equation.
[tex]42=2W+2(2W+3)[/tex]
Expand the right side of the equation then simplify.
[tex]42=2W+4W+6\\42=6W+6[/tex]
Subtract 6 from both sides.
[tex]36=6W[/tex]
Divide both sides by 6 to isolate [tex]W[/tex].

Using the normal distribution, the middle 50% would be expected to be in the range of 250 to 270 days.
Using the central limit theorem, for the samples of 36, the middle 50% would be expected to be in the range of 258 to 262 days.
What is normal distribution theorem?A sort of continuous probability distribution for a real-valued random variable is the normal distribution or the Gaussian distribution.
Normal Distribution of Probabilities
The z-score formula, which for a measure X, in a set with mean and standard deviation, is given by: can be used to address problems with normal distributions.
Z = (X - μ)/σ
The z-score calculates the measure's standard deviation from the mean.
A p-value, or percentile of X, is assigned to each z-score.
Mean (μ) = 260.
Standard deviation (σ)= 15 .
The normal distribution is symmetric, which means that the middle 50% is between the 25th percentile and the 75th percentile.
The 25th percentile is X when Z has a p-value of 0.25, so X when Z = -0.675.
The 75th percentile is X when Z has a p-value of 0.75, so X when Z = 0.675.
Lower bound:
Z = (X - μ)/σ
⇒ -0.675 = (X - 260)/15
⇒ X - 260 = -0.675*15
⇒ X - 260 = -10.125
⇒ X = 260 - 10.125
⇒ X ≈ 250
Upper bound:
Z = (X - μ)/σ
⇒ 0.675 = (X - 260)/15
⇒ X - 260 = 0.675*15
⇒ X - 260 = 10.125
⇒ X = 260 + 10.125
⇒ X ≈ 270
The middle 50% of pregnancies would be in the range of 250 to 270 days.
For sample of 36: By the Central Limit Theorem, the standard deviation of the sampling distribution of sample means of size n is given by .
Sample of 36, thus n=36, s=15/√36
⇒ s=15/6
⇒ s=2.5
Lower bound:
Z = (X - μ)/s
⇒ -0.675 = (X - 260)/2.5
⇒ X - 260 = -0.675*2.5
⇒ X - 260 = -1.69
⇒ X = 260 - 1.69
⇒ X ≈ 258
Upper bound:
Z = (X - μ)/s
⇒ 0.675 = (X - 260)/2.5
⇒ X - 260 = 0.675*2.5
⇒ X - 260 = 1.69
⇒ X = 260 + 1.69
⇒ X ≈ 262

At a constant temperature the volume of a gas is inversely proportional to its mass…
a) The volume of the gas is 0.923 x [tex]10^{-6}[/tex] m³.
b) The pressure of the gas is 0.532 x [tex]10^7[/tex] Pascals.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
3 = 4k is an equation.
We have,
Volume of a gas (V) ∝ 1/ Pressure of a gas (P)
This can be written as,
Volume of a gas = K / Pressure of a gas
K = VP
Now,
P =1.8 x [tex]10^6[/tex] Pascals
V = 2.1 x [tex]10^{-8}[/tex] m³
K = VP = 1.8 x 2.1 x [tex]10^{-2}[/tex]
k = 3.78 x [tex]10^{-2}[/tex] pascal m³
Now,
P = 4.1 x [tex]10^4[/tex] Pascals
V = K/P = 3.78 x [tex]10^{-2}[/tex] Pascal m³ / 4.1 x [tex]10^4[/tex] Pascals
V = 0.923 x [tex]10^{-6}[/tex] m³
Now,
V = 7.1 x [tex]10^{-9}[/tex] m³
P = k/V = 3.78 x [tex]10^{-2}[/tex] Pascal m³ / 7.1 x [tex]10^{-9}[/tex] m³

Beth is making gingerbread men. She uses 2 raisins for eyes and 3 raisins for buttons for each gingerbread man. She buys 4 boxes of raisins, each with 120 raisins in it. How many dozens of gingerbread men can she make?
Answer: 96
Step-by-step explanation: This is how to solve:
120 * 4
= 480
3 + 2 = 5
480 / 5
= 96
First, you need to multiply the boxes bought by the total amount inside the box. (120 * 4)
The, we need to find how many raisins she uses IN TOTAL for each gingerbread man. So, we need to add 3 + 2
This equals 5
So, 120 * 4 = 480
So, in total, she buys 480 raisins. So, to find how much gingerbread she can make, we need to divide 480 by 5. This would get you 96. I hope this helps ;)
Which one of the following is arithmetic sequence? 15, 12, 9, 6 … 15, 30, 60, 120 … 1, 4, 9, 16 … 1, 8, 27, 64 …
An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a fixed number, called the common difference, to the previous term. For example, the sequence 15, 12, 9, 6, … is an arithmetic sequence because each term is obtained by subtracting 3 from the previous term, which is the common difference. On the other hand, the sequence 15, 30, 60, 120, … is not an arithmetic sequence because the difference between each consecutive pair of terms is not constant. The same is true for the sequences 1, 4, 9, 16, … and 1, 8, 27, 64, …. Therefore, the only arithmetic sequence among the given options is 15, 12, 9, 6, ….
