Answer:
The two bases of a rectangular prism are rectangles, while the two bases of a triangular prism are triangles.
Step-by-step explanation:
Any prism has two bases. Since we are talking about a rectangular prism and a triangular prism both must have two bases.
For example, a square prism has two bases and they are both square.
In this case a rectangular prism has two bases that are rectangles and a triangular prism also has two bases and both bases are triangles.
Note: For the figure to have only one base it must be called a pyramid.
Thus, the answer is:
The two bases of a rectangular prism are rectangles, while the two bases of a triangular prism are triangles

Julie conducts an experiment to find the average word length in a book for a 4th grader and a book for a 8th grader. She finds that for the fourth grade book the mean word length is 5 letters with a range of 6 and for the 8th grade book the mean word length is 6 letters with a range of 9. Which statement is true?
A) On average, the book for the 4th grader has longer words.
B) There is not enough information to know if any of the above are true.
C) The word length varies more in the 8th grade book than the 4th grade book.
D) The longest word in the book for the 4th grader is longer than that in the 8th grade book.
Answer: C
Step-by-step explanation: I chose this answer because in 8th graders, their mean is 6 and their range is 9, that’s a difference of 3. But in 4th graders, their mean is 5 and their range is 6, so there isn’t much of a difference for 4th graders. The answer couldn’t be A, B, or D so I came to the conclusion that it’s C. (Sorry if this explanation doesn’t make sense but I hope I got the right answer.)
The true statement is the word length varies more in the 8th grade book than the 4th grade book.
Mean is a measure of central tendency. It is the average of a set of values. For example, if the numbers in a data set are 3,2,10, the mean is (3 + 2 + 10) /3 = 5
Range is the highest number less the least number in a data set. For example, if the numbers in a data set are 3,2,10, the range is 10 - 2 = 7
The mean word length for the fourth grade book is 5. While, the mean word length for the eighth grade book is 6. This means that on average, the average word length of the eighth grade book is greater than the mean word length for the fourth grade book
The range word length for the fourth grade book is 6. While, the range word length for the eighth grade book is 9. These means that either the longest word in the eighth grade book is more than that of the fourth grade book or that the smallest word in the eighth grade book is less than than that in the fourth grade book. This means that the word length varies more in the 8th grade book than the 4th grade book.

Answer:
82
Step-by-step explanation:
shown in the image. hope it helps :)
At the intersection of lines b and e, the bottom right angle is x degrees. the value of x is Option B ; 82.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
We know that the point where two lines meet is known as an angle.
We can conclude that lines e and f are parallel because their alternate exterior angle is congruent.
y + x = 180
x = 180 - 98
x = 82
Thus, At the intersection of lines b and e, the bottom right angle is x degrees. the value of x is Option B ; 82.

Find an equation equivalent to r = 6secx in rectangular coordinates and describe the graph of the equation.
A. x · [tex]\sqrt{x^{2} + y^{2} }[/tex] = 6; circle with radius 6
B. [tex]\sqrt{x^{2} + y^{2} }[/tex] = 6; circle with radius 6
C. x = 6; straight vertical line
D. y = 6; straight horizontal line
Answer:
C. x = 6; straight vertical line
Step-by-step explanation:
you have the following equation in polar coordinates:
[tex]r=6sec(\theta)[/tex]
To find the equation in rectangular coordinates you take into account the following transformations:
[tex]r=\sqrt{x^2+y^2}\\\\x=rcos(\theta)\\\\[/tex]
Next, you replace and obtain:
[tex]r=6sec(\theta)\\\\r=\frac{6}{cos(\theta)}\\\\rcos(\theta)=6[/tex]
but, you have that x = rcos(θ), hence, x = 6
C. x = 6; straight vertical line
Last year, Deshaun had $20,000 to invest. He invested some of it in an account that paid 9% simple interest per year, and he invested the rest in an account that paid 5% simple interest per year. After one year, he received a total of $1440 in interest. How much did he invest in each account?
Answer:
the amount Deshaun invested in an account that paid 9% interest = $9,000
the amount Deshaun invested in an account that paid 5% interest = $11,000
Step-by-step explanation:
Let x = the amount Deshaun invested in an account that paid 9% interest
Let y = the amount Deshaun invested in an account that paid 5% interest.
Thus;
x + y = 20,000 - - - - (eq 1)
Now, After one year, he received a total of $1440 in interest. Thus;
0.09x + 0.05y = 1440
Multiply each term by 100 to give;
9x + 5y = 144000 ---- (eq 2)
Making x the subject in equation 1,we have;
x = 20,000 - y
Putting 20,000 - y for x in eq 2,we have;
9(20,000 - y) + 5y = 1440
180000 - 9y + 5y = 144000
180000 - 4y = 144000
180000 - 144000 = 4y
36000 = 4y
Divide both sides by 4 to give;
y = 36000/4
y = $9,000
x = 20,000 - 9000
x = $11,000

explains whether Talia is correct and why?
PLEASE HELP
-Talia is correct. The three faces have the same area base, and the area of the base is 1/2(8)(6.9)
-Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4( 1/2 (8)6.9) )
-Talia is not correct. Only the base has an area of 1/2(8)(6.9), and three other faces have a different area.
-Talia is not correct. The lateral Area has three faces, so the expression should be 3( 1/2(8)6.9) )
Answer:
Talia is not correct. The lateral Area has three faces, so the expression should be 3( 1/2(8)6.9) )
Step-by-step explanation:
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. This means that all three of the triangles that make up the faces of the triangular prism must be equal.
Since the dimensions of the base is known as 8 inches at the base and 6.9 inches high, the area of the base will be half the base times the height which is 1/2 x (8)(6.9).
The total surface area will be 3 times this area which will be,
Total surface area = 3( 1/2(8)6.9) )
What is the next term in this sequence: 76, 80, 88, 95, 100, 101
I’m stuck
Answer:
112Step-by-step explanation:
Given the sequence 76, 80, 88, 95, 100, 101... Before we can get the next term of the sequence, we must first understand the pattern. We are not going to be considering all the terms of the sequence. In the sequence, only the following values forms a pattern as shown;
76, 88, 100... This are the first, third and fifth term of the sequence. The next term will be the 7th term of the sequence and the 4th term of the extracted sequence which is what we are looking for.
Note that the extracted forms an arithmetic sequence with 76 as its first term and 12 as its common diffidence (i.e 88-76 = 100-88).
Using the nth term of an AP to find the next term of the sequence we have;
[tex]Tn = a + (n-1)d[/tex]
a is the first term = 76
d is the common difference = 12
n is the number of terms = 4 (since we are looking for the 4th term of the extracted sequence)
[tex]T4 = 76+(4-1)*12\\T4 = 76 + (3*12)\\T4 = 76 + 36\\T4 = 112[/tex]
The next term in the sequence is 112

Determinado automovel, apos sua compra, perde 10% do valor ano a ano nos 3 preimeiros anos. Calcule o valor do automovel ao final desse periodo sabendo que ele foi comprado por R$80.000
Answer:
The value of the car after 3 years is R$58.320.
O valor do carro ao final desse período é R$58.320.
Step-by-step explanation:
The value of the car after t years is given by the following equation:
[tex]V(t) = V(0)(1-r)^{t}[/tex]
In which V(0) is the initial value and r is the yearly depreciation rate.
In this question, we have that:
[tex]V(0) = 80000, r = 0.1[/tex]
So
[tex]V(t) = V(0)(1-r)^{t}[/tex]
[tex]V(t) = 80000(1-0.1)^{t}[/tex]
[tex]V(t) = 80000(0.9)^{t}[/tex]
Value of the car at the end of 3 years:
[tex]V(3) = 80000(0.9)^{3} = 58320[/tex]
The value of the car after 3 years is R$58.320.
O valor do carro ao final desse período é R$58.320.

He base of a pentagonal prism has an area of 2.4 m2. The prism has a volume of 4.8 m3. What is its height? Use sketches, formulas and/or charts to justify your answer
Answer:
The height of the prism is 2m
Step-by-step explanation:
Given;
The volume of pentagonal prism, V = 4.8 m^3
Area of the prism, A = 2.4 m^2
To determine the height of the prism, we consider the following;
Volume of any prism = Area of the prism x height of the prism
Height of the prism = volume of the prism / Area of the prism
Height of the prism = 4.8 / 2.4
Height of the prism = 2 m
Therefore, the height of the prism is 2m
