Rewrite as equivalent rational expressions with denominator (5c+9)(c−3)(c−8): 8/5c^2-6c-27, 2c/5c^2-31c-72
Answers
The equivalent rational expression with the same denominator as given will be 8(c - 8)/[(c - 3)(5c - 9)(c - 8)] and 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)].
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression,
8/(5c² - 6c - 27) , 2c/(5c² - 31c - 72)
Now, take the first denominator,
5c² - 6c - 27 = 5c² - 15c + 9c - 27
⇒ 5c(c - 3) - 9(c - 3)
⇒ (c - 3)(5c - 9)
Take the second denominator
5c² - 31c - 72 = 5c² - 40c + 9c - 72
⇒ 5c(c - 8) + 9(c - 8)
⇒ (c - 8)(5c + 9)
Therefore, the expression converts as,
8/[(c - 3)(5c - 9)] , 2c/[(c - 8)(5c + 9)]
8/[(c - 3)(5c - 9)] = 8(c - 8)/[(c - 3)(5c - 9)(c - 8)]
2c/[(c - 8)(5c + 9)] = 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)]
The denomiantor of both expression are same.
Hence "The equivalent rational expression with the same denominator as given will be 8(c - 8)/[(c - 3)(5c - 9)(c - 8)] and 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)]".

Mary Granola consumes tomatoes and nectarines. Mary's indifference curves are kinky. When she is consuming more tomatoes than nectarines, she is just willing to trade 3 tomatoes for 1 nectarines. When she is consuming more nectarines than tomatoes, she is just willing to trade 4 nectarines for 1 tomatoes. Let P₁ be the price of nectarines and P₂ the price of tomatoes. Mary maximizes her utility subject to her budget constraint. Which is true? (Hint: Sketch one of her indifference curves.)

When P₁ >3P₂ she must consume only tomatoes.
What are indifference curves ?
An indifference curve is a graph that illustrates numerous pairings of two goods or commodities that leave the customer equally well off or satisfied—hence indifferent—when it comes to owning any pairing of the two items that is represented along the curve.
Mary do trading 3 tomatoes for 1 nectarine.
So, MRS=3

True
O False
Answers
It is true, Mai can conclude that the diagonal WY bisects the angles ZWX and ZYX
Since Mai has proven triangles WYZ and WYX to be congruent by the SSS triangle Congruence Theorem, she can conclude that:
Diagonal WY bisects angles ZWX and ZYX because:
all corresponding parts of both triangles are congruent. (Option A).
If two triangles are proven to be congruent to each other, it means that all three pairs of corresponding sides and angles of both triangles are congruent and equal to each other.
Thus, since Mai has proven triangles WYZ and WYX to be congruent by the SSS Triangle Congruence Theorem, therefore, all corresponding parts of both triangles are congruent.
If this is so, then Mai can conclude that angles ZWX and ZYX are bisected by diagonal WY. (Option A is correct).

Answers
Estelle has deposited $6350 in her bank account when the simple interest was 2.5% per year.
According to the question,
We have the following information:
In 8 years, Estelle's bank account earned $1,270 simple interest at 2.5%.
Now, let's take the principal amount to be $x.
We know that the following formula is used to find simple interest:
Simple interest = (principal*rate*time)/100
(x*2.5*8)/100 = 1270
Using the cross multiplication method:
20x = 127000
x = 127000/20
x = $6350

Let's multiply the top equation by -2. What would be our new equation?
2x + 3y = 12
4x - 7y = -54
Answers
New equation will be 4x + 6y = 24, if we multiply the equation 2x + 3y = 12 by -2.
Define multiplication.We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group. A fact involving multiplication is the result of two distinct integers. Additionally, the product is unaffected by the arrangement of the numbers. For instance, 32=6 and 23=6. The distributive, commutative, associative, removes a common factor, and neutral element characteristics of multiplication.
Given,
Equations:
2x + 3y = 12
4x - 7y = -54
Multiplying the top equation by -2:
-2(2x + 3y) = -2(12)
-2(2x) -2(3y) = -24
Product:
-4x - 6y = -24
Taking - common,
-(4x + 6y) = -24
4x + 6y = 24
New equation will be 4x + 6y = 24, if we multiply the equation 2x + 3y = 12 by -2.

How to calculate Boat and Stream?The four terms that a candidate has to comprehend in order to grasp the notion of streams are listed below.Stream: A river's flowing water is referred to as a stream.Upstream - A boat is said to be moving upstream if it is moving downstream of the stream. The boat's upstream speed in this situation is its net speed.Downstream - A boat is said to be moving downstream if it is moving in the same direction as the stream. In this instance, the boat's downstream speed is its net speed.Still Water - In this situation, the water is seen as being immobile and has no speed.The main focus of this topic is determining the speed of anything moving through water, whether it is moving with the current or against it.For example : In one hour, a boat goes 13 km/hr in the direction of the stream and 7 km/hr against the direction of the stream. What will be the speed of the boat in still water?Utilizing the formula,Boat speed in still water = 1/2 (downstream speed + upstream speed).
Boat's speed in still water equals 1/2 (13+7) = 1/2 × 20 = 10 km/hr.
