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
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
A spinner has 5 equal sections numbered 1 to 5. What is the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3?
HELPPPP!!!
Answer:
0.6
Step-by-step explanation:
Given that the spinner has 5 equal sections numbered 1 to 5.
Total Sample Space, n(S)=5Multiples of 2 in 1 to 5 are: {2,4}
Number less than than 3 are:{1,2}
Since we are required to find the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3, we take the union of both sets.
{2,4} [tex]\cup[/tex] {1,2} ={1,2,4}
Number of Outcomes=3
Therefore,
Probability of the spinner stopping on a number that is a multiple of 2 or is less than 3 [tex]=\dfrac{3}{5}=0.6[/tex]

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.

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

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
What is the distance between these two points.
Answer:
It's C, under root of 32
Step-by-step explanation:
under root of (x2 - x1)^2 plus (y2 - y1)^2
under root of (4-8)^2 + (-7+3)^2
under root of (-4)^2 + (-4)^2
under root of 16 + 16
under root of 32
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving the given problem using the distance formula.
Problem: What is the distance between (8, -3) and (4, -7)?
From inspection on the given problem:
[tex]\sf (x_1, y_1) = (8, -3)[/tex][tex]\sf (x_2, y_2) = (4, -7)[/tex]Substitute the given values into the distance formula and solve for d:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf d = \sqrt{(4 - 8)^2 + [-7 - (-3)]^2}[/tex][tex]\sf d = \sqrt{(4)^2 + (-4)^2}[/tex][tex]\sf d = \sqrt{16 + 16}[/tex][tex]\bold{d = \sqrt{32} \approx 5.66 \: units}[/tex]Therefore, the distance between two points is [tex]\sqrt{32}[/tex] or 5.66 units.

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.

A: 2/5+1/5
Answer:
3/5
Step-by-step explanation:
2/5 + 1/5
The denominator is the same, so we add the numerators
3/5
Answer:
3/5
Step-by-step explanation:
We need to add the two fractions 2/5 and 1/5.
First, see if we need to find their common denominator: they both have a denominator of 5, so we're all set there!
Now, just add the numerators together:
2/5 + 1/5 = (2 + 1)/5 = 3/5
The denominator will stay 5 (don't add the 5's together).
The final answer is thus 3/5.
