An inequality is used to show two values that are different and to show that the two values are unequal.
What is an Inequality?This refers to the mathematical relation that is used to show the comparison between two numbers that are unequal.
We can note that because there is a previous record, for a person to beat the record, he would have to perform better than the record and be faster than the previous record holder.
Therefore, if a record of Amelia was given, this would be used to find the relation between her record and the current record of 37 sit-ups and how many weeks of training would be needed to break the record.
Hence, we can see that the question is incomplete so I gave you a general overview to help you get a better understanding.

A triangle has sides with lengths of 31 feet, 72 feet, and 78 feet. Is it a right triangle?
yes
no
=========================================================
Explanation:
We have a triangle with these side lengths
a = 31b = 72c = 78The order of 'a' and b doesn't matter, but we must have c as the largest value. Usually a,b,c are in ascending order.
Plug those values into the formula for the pythagorean theorem. If we get the same thing on both sides, then we have a right triangle.
[tex]a^2 + b^2 = c^2\\\\31^2 + 72^2 = 78^2\\\\961+5184 = 6084\\\\6145 = 6084\\\\[/tex]
We have a false statement at the end, which means the original equation is false for those a,b,c values.
Therefore, we do not have a right triangle.
Instead, this triangle is acute since the [tex]a^2+b^2[/tex] side is larger than the [tex]c^2[/tex] side
---------------
Rules to have in your notebook or on a reference sheet:
[tex]\text{If }a^2 + b^2 = c^2 \text{ then it is a right triangle}\\\\\text{If }a^2 + b^2 > c^2 \text{ then the triangle is acute}\\\\\text{If }a^2 + b^2 < c^2 \text{ then the triangle is obtuse}\\\\[/tex]

Answer:
Pr(Cb) & Pr(cost $15) = 15(Ncb)/(T1×T3)
Step-by-step explanation:
Classification of the book in to 3
First let's assign terms to each probability
Let:
T1= total number of type of Reader's group
T2 = total number of Type of book
T3 = total number of type of Cost
Probability of child's book and cost $15= Pr(Cb) & Pr(cost $15)
Then find probability of child's book and cost separately:
Pr of child's book = Pr(Cb)
Pr(Cb) = (number of child's book)/ total number of type of group
Ncb = number of child's book
Pr(Cb) = Ncb/T1
Pr (cost $15) = $15 book/total number of cost
Pr (cost $15) = 15/T3
probability of child's book and cost $15 = Pr(Cb) × Pr (cost $15)
= Ncb/T1 × 15/T3
Pr(Cb) & Pr(cost $15) = 15(Ncb)/(T1×T3)

Isosceles triangles have 2 congruent sides (in this case they are KM and LM
This means 4d-13 = 12-d
We can now solve for d
4d-13 = 12-d | add d to both sides
5d-13 = 12 | add 13 to both sides
5d = 25 | divide both sides by 5
d = 5

Identify the growth factor for the following exponential function: y= 2.3(1.32)*
A. 2.3
B. 1.32
C. X
D. 32%
Answer:
D. 32%
Step-by-step explanation:
In an exponential function, exponential growth is modeled by f(x) = a(1 + [rate])ˣ. In this function, the initial value a, which is 2.3, is multiplied by 1.32 x times, so 1.32 represents the actual growth happening.
This means that to find the actual rate of exponential growth, you’d have to set 1.32 equal to (1 + [rate]). If (1 + [rate]) = 1.32, then the rate = .32, and because rates are written as percentages, we change .32 to 32%.
