Since m<B is equal to m<E, hence the angles are similar triangles
To determine if both triangles are similar, all the interior angles of the triangles must be equal to each other that is;
m<B = m<Em<C = m<FGet the measure of angle B
The measure of the interior angle of the triangle is 180 degrees
m<D + m<E + m<F = 90
90 + m<E + 55 = 180
m<E = 180 - 145
m<E = 35 degrees

The selling price of an item is $650 It is marked down by
10%, but this sale price is still marked up from the cost of $450
Find the markup from cost to sale price.
Answer:
10%×$650=$585
$585-$450=$135 Mark up.
Step-by-step explanation:
The markup from cost to sale price is $135.
What is the cost price?Cost price, for instance, equals selling price plus profit ( when selling price and profit is given ) Cost is equal to Selling price plus Loss ( when selling price and loss is given )
Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)
Given the selling price of item = $650
The cost = $450
Therefore,
10% × $650 = $585
$585-$450=$135
Hence, the markup from cost to sale price is $135.

WHAT IS THE RELATIONSHIP BETWEEN A DOMAIN, RELATION, AND RANGE??????
The relationship between a domain, relation, and range in mathematics is that the domain represents the set of input values, the relation shows the relationship between input and output values, and the range represents the set of output values.
Explanation:In mathematics, "a domain is the set of input values or independent variable in a relation or function". It represents the possible values for the input variable. A relation is a set of ordered pairs that shows the relationship between the input and output values. The range of a relation is the set of output values or dependent variable.
For example, let's consider a relation that relates the ages of students to their heights. The ages of the students would be the domain, the heights would be the range, and the ordered pairs would represent the relationship between age and height.

Pilar saved a total of $0.50 by using five reusable shopping bags, with each bag providing a $0.10 discount on her purchase.
Pilar used five reusable shopping bags for a recent purchase she made at a grocery store, where each bag decreased the amount she spent by $0.10. To calculate the total amount saved by Pilar, we must multiply the number of bags by the savings per bag. So the calculation is as follows:
Number of reusable bags = 5
Savings per bag = $0.10
Total savings = Number of reusable bags imes Savings per bag = 5 imes $0.10 = $0.50
Therefore, by using the reusable bags, Pilar saved a total of $0.50 on her grocery purchase.

Solve for x, assuming a, b, and c are negative constants.
(ax + b)/c ≤ b
Solving for some variable means finding its value for which the given statement is true. Thus, the solution to given inequality is [tex]x \leq \dfrac{b(c-1)}{a}[/tex] (if a/c is non-negative)or [tex]x \geq \dfrac{b(c-1)}{a}[/tex] (if a/c is negative)
What type of operations are allowed in inequality?All such operations such that inequality doesn't gets modified( for example, if left expression is bigger than right one, then that expression cannot go bigger than the later expression).
For the given case, the inequality given is:
[tex](ax+b)/c \leq b[/tex]
Its solution can be found by doing operations which doesn't modify the inequality and takes all the terms such that one side is 'x' and other side are constants.
[tex](ax+b)/c \leq b\\\\\dfrac{a}{c}x + \dfrac{b}{c} \leq b\\\\\text{Subtracting b/c from both the sides}\\\\\dfrac{a}{c}x \leq b - \dfrac{b}{c}\\\\\text{Supposing that a/c is non-negative, multiplying both sides by c/a}\\\\x \leq \dfrac{c}{a} \times \dfrac{bc - b}{c} = \dfrac{b(c-1)}{a}\\\\x \leq \dfrac{b(c-1)}{a}[/tex]
(i assumed a/c non-negative, since multiplying with negative quantity can modify the sign of inequality, so ≤ would have become ≥ )
If a/c is negative, then:
[tex]x \geq \dfrac{c}{a} \times \dfrac{bc - b}{c} = \dfrac{b(c-1)}{a}\\\\x \geq \dfrac{b(c-1)}{a}[/tex]
Thus, the solution to given inequality is [tex]x \leq \dfrac{b(c-1)}{a}[/tex] (if a/c is non-negative)
or [tex]x \geq \dfrac{b(c-1)}{a}[/tex] (if a/c is negative)

https://brainly.com/question/11901702
Final answer:
To solve for x, we can multiply both sides of the equation by c, subtract b from both sides, and then divide both sides by a to isolate x. The solution is x ≤ (bc - b)/a.
Explanation:
To solve for x in the equation (ax + b)/c ≤ b, we can first multiply both sides of the equation by c to eliminate the denominator:
ax + b ≤ bc
Next, we can subtract b from both sides:
ax ≤ bc - b
Finally, we divide both sides by a to isolate x:
x ≤ (bc - b)/a
Since a, b, and c are negative constants, the values of b and c are negative. Therefore, the numerator of the inequality will always be negative, resulting in a positive value for x. So the solution is:
x ≤ (bc - b)/a

Answer:
Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation . ... If the line goes from a high-value on the y-axis down to a high-value on the x-axis, the variables have a negative correlation . A perfect positive correlation is given the value of 1.
a cricket chirps 40 times a minute when the temperature is 50 degrees. write an equation representing the temperature in terms of number of chirps per minute
The relationship between temperature and the number of chirps per minute can be represented by the equation C = 0.8T, where C is the number of chirps per minute and T is the temperature.
Explanation:The relationship between the temperature and the number of chirps per minute can be represented by an equation.
Let's assume that the temperature is denoted by T and the number of chirps per minute is denoted by C. According to the given data, when the temperature is 50 degrees, the cricket chirps 40 times per minute. We can use this information to write the equation as:
C = kT
where k is a constant.
To solve for the value of k, we can substitute the temperature and the number of chirps per minute into the equation:
40 = k * 50
Dividing both sides by 50 gives us:
k = 40/50 = 0.8
Therefore, the equation representing the temperature in terms of the number of chirps per minute is:
C = 0.8T

A. the number of miles Dee drove each hour
B. the number of miles Dee had to drive before she started
C. the number of miles Dee drove in h hours
D. the number of miles Dee had left to drive after driving h hours
The statement that best represents the meaning of the term 60h is:
C. the number of miles Dee drove in h hours
Step-by-step explanation:The expression 705 – 60h gives the number of miles Dee is from home after driving h hours.
This means that initially he is: 705 miles away from the home.
Now, he is travelling at a speed of 60 miles per hour.
This means that the distance he travels in h hours is: 60h miles.

yasmine bought 6 gallons of apple juice. after filing up 4 bottles of the same juice, she had 0.3 gallons of apple juice left. What's the amount of apple juice in each bottle?
1.425 gallons/bottle
Further explanationGiven:
Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same juice, she had 0.3 gallons of apple juice left.Question:
What is the amount of apple juice in each bottle?
The Process:
Let the amount of apple juice in each bottle as X.
The two steps for obtaining X are as follows:
Step-1: the total amount of apple juice is the initial gallon amount subtracted by the remaining gallon amount.
[tex]\boxed{ \ 6 \ gallons - 0.3 \ gallons = 5.7 \ gallons \ }[/tex]
Step-2: the total amount of apple juice divided by the number of bottles is the amount of apple juice in each bottle.
[tex]\boxed{ \ X = 5.7 \ gallons \div 4 \ bottles = \boxed{ \ 1.425 \ gallons/bottle \ } \ }[/tex]
Quick steps:
[tex]\boxed{ \ X = \frac{(6 - 0.3) \ gallons}{4 \ bottles} = \boxed{ \ 1.425 \ gallons/bottle \ } \ }[/tex]
Thus, the amount of apple juice in each bottle is 1.425 gallons.

In order to simplify, we want to change the 10 - x to an x - 10.
To do that, we can factor out a -1.
So we have -1(x - 10)/(x - 10).
Now our x - 10's cancel leaving us with -1.
11x-9=108 What is the answer to this equation?
11x-9 = 108
add 9 to both sides:
