The length of a rectangle is 5 in. more than 3 times its width. the area of the rectangle is 50in.2. a quadratic function represents the dimensions of the rectangle. what is the domain of the function?
Assume ABC DEF. If AB = 12, BC = 15, and AC = 17, what is the length of EF? A. 15 B. 17 C. Cannot be determined D. 10
Answer:
Option A) EF = 15 units.
Step-by-step explanation:
We are given the following information in the question:
ΔABC ≅ ΔDEF
AB = 12, BC = 15, and AC = 17
If two triangles are congruent then they have the following properties:
AB = DE
BC = EF
AC = DF
[tex]\angle A = \angle D \\\angle B = \angle E \\\angle C = \angle F[/tex]
Hence, by congruency:
BC = EF
EF = 15 units.
Thus, option A is the correct answer.
In modified boxplots, a data value is a(n) _______ if it is above q3plus+(1.5)(iqr) or below q1minus−(1.5)(iqr).
In modified boxplots, a data value is a potential outlier if it is outside the range of Q3 + (1.5)(IQR) or Q1 - (1.5)(IQR). The IQR is the spread of the middle 50% of the data, calculated as Q3 - Q1.
Explanation:In modified boxplots, a data value is a potential outlier if it is above Q3 + (1.5)(IQR) or below Q1 - (1.5)(IQR). The interquartile range (IQR) is crucial in this determination, representing the spread of the middle 50 percent of the data. It is found by subtracting the first quartile (Q1) from the third quartile (Q3). For example, if Q1 is 2 and Q3 is 9, the IQR is 7. Any data value greater than 9 + (1.5)(7) or less than 2 - (1.5)(7) would be considered a potential outlier.
Constructing a box plot involves identifying these five key values: minimum value, first quartile, median, third quartile, and maximum value. The box plot visually represents the data's spread, with whiskers extending to the most extreme values within the acceptable range, and separate marks for potential outliers.

Lorrae swims at a constant speed, s, for 2 hours. Create a formula for the distance she swims, d.
The formula for the distance Lorrae swims at a constant speed for 2 hours is d = 2s, where d is distance and s is her speed.
Explanation:The question is asking for a formula to calculate the distance that Lorrae swims. Since distance (d) is equal to speed (s) multiplied by time (t), and we know that Lorrae swims at a constant speed, s, for 2 hours, a formula for her distance would be d = s * t.
In this case, the time, t, is 2 hours. So, we can substitute t with 2 in our formula. Hence, the formula for the distance Lorrae swims is d = s * 2 or d = 2s. This is the equation you can use to compute the distance Lorrae swims for any given speed at a constant period of 2 hours.

Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms?

A. 11x = 55
B. 5x = 55
C. 9x = 55
D. 5y = 55
Answer: A(11x=55)
Step-by-step explanation:
in the equation 2x + 3y = 55, subsitute 3y for 3x, because y = 3x. this will result in the equation 2x + 3(3x) which equals 11x. so 11x=55

If the volumes of two similar rectangular prisms are 40mm and 135mm find the scale factor of the two rectangular prisms.
(The answers are in fraction form)
A. 1/4
B. 8/27
C. 3/5
D. 2/3
The scale factor of the two rectangular prisms is 3/2 of the given problem the volumes of two similar rectangular prisms are 40 mm and 135 mm
To find the scale factor between two similar rectangular prisms, we can compare their volumes. The scale factor is the ratio of the cube root of the volumes.
Let's denote the volume of the first rectangular prism as V1 and the volume of the second rectangular prism as V2.
[tex]V1 = 40 mm^3\\V2 = 135 mm^3[/tex]
The scale factor (SF) can be calculated as follows:
[tex]SF = (V2)^{(1/3)} / (V1)^{(1/3)[/tex]
Plugging in the given values:
[tex]SF = (135)^{(1/3)} / (40)^{(1/3)[/tex]
To simplify the calculation, we can rewrite the values as prime factorization:
[tex]135 = 3^3 * 5\\40 = 2^3 * 5[/tex]
Now, let's calculate the cube roots:
[tex]SF = (3^3 * 5)^{(1/3) }/ (2^3 * 5)^{(1/3)}[/tex]
Using the property of exponents [tex](a^{(m/n) }= (a^m}^{(1/n)})[/tex]:
[tex]SF = (3^{(3/3)} * 5^{(1/3)}) / (2^{(3/3)} * 5^{(1/3)})[/tex]
Simplifying the fractions:
[tex]SF = 3 * 5^{(1/3)} / 2 * 5^{(1/3)[/tex]
The [tex]5^{(1/3)}[/tex] terms cancel out:
SF = 3/2
Therefore, the scale factor of the two rectangular prisms is 3/2 of the given problem the volumes of two similar rectangular prisms are 40 mm and 135 mm.

Wilma and Betty are playing a number game. Wilma tells Betty, "I'm thinking of a number between 1 and 10. If I take the number and add 4 to it and then multiply that by 3, I get 30." What number is Wilma thinking of?
To find the number Wilma is thinking of, we create an equation and solve for x.
Explanation:To solve this problem, we need to create an equation based on the information given. Let's suppose the number Wilma is thinking of is x. According to the problem, if we add 4 to x and then multiply that result by 3, we get 30. We can write this as the equation 3(x + 4) = 30. To find the value of x, we need to isolate it. First, distribute the 3 to both terms inside the parentheses: 3x + 12 = 30. Next, isolate x by subtracting 12 from both sides of the equation: 3x = 18. Finally, solve for x by dividing both sides of the equation by 3: x = 6. Therefore, Wilma is thinking of the number 6.

125/225
5/9
how did you get (225-110)? if it's 100/225
Answer: 5/9 will be the fraction of the space will be for storage and baking.
Step-by-step explanation:
Since area of bakery will be used as our storefront, where customers come to visit= 100/225
Thus, the total area of bakery = 225
And, the area will be used our storefront, where customers come to visit= 100
So, the remaining area which is used for storage and baking = 225 - 100 =125
So the part of area which is used for storage and baking= the remaining area which is used for storage and baking/ total area
=125/225= 5/9
which is the simplest form.

Answer:
CPCTC; JP≅MI; SAS
Step-by-step explanation:
For the first question, we use the congruence statement. When we are using the congruence statement to match corresponding pieces, the justification is that Congruent Parts of Congruent Triangles are Congruent, or CPCTC.
For the second question, we again use CPCTC and the congruence statement. P matches T and B matches I, so PB = TI and B = I. J matches M also, so BJP = IMT. However, P does not match I, so JP does not equal MI.
For the third question, we have two sides (AM matching ZD and BD matching itself) and an included angle (AMD and ZDM). This is Side-Angle-Side, or SAS.

True or false? To begin an indirect proof, you assume the converse of what you intend to prove is true.
A. True
B. False
Answer:
The statement is false.
Step-by-step explanation:
To begin an indirect proof, you assume the converse of what you intend to prove is true. This is false.
Rather the correct answer is that to begin an indirect proof, you assume the inverse of what you intend to prove is true.
The converse can be either true or false, depending on what the original statement is, so assuming the converse is pointless.
