jamie reads 15 pages in 25 minutes and wants to know how many pages she can read in 65 minutes
Answer:
39
Step-by-step explanation:
15/25 = 0.6 - She can read 0.6 pages in 1 minute.
0.6 X 65 = 39
There are 39 pages she can read in 65 minutes.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
Jamie reads 15 pages in 25 minutes
And, wants to know how many pages she can read in 65 minutes
Now, Let number of pages read in 65 minutes = x
Hence, We can formulate;
x / 65 = 15 / 25
x = 15 x 65 / 25
x = 39
Thus, There are 39 pages she can read in 65 minutes.

What is the Least Common Multiple (LCM) of 3 and 6?
Answer:
6
Step-by-step explanation:
Both numbers can evenly go into 6: 3 can go into 6 two times, and 6 can go into 6 one time.I hope this helps!
The LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.
What is Least Common Multiple(LCM)?The least common multiple is defined as the least positive integer that is dividable by both given numbers.
A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers.
We can use the prime factorization method to find the LCM. We can write each number as a product of its prime factors:
3 = 3
6 = 2 x 3
The LCM is the product of the highest powers of all the prime factors.
Here, the highest power of 2 is 2, and the highest power of 3 is 3. So, the LCM is:
LCM(3, 6) = 2 x 3 = 6
Thus, the LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.

When converting rational exponents to radical notation, which of the following are correct? Choose all that apply:
1. Numerator of the rational exponent becomes index of the radical notation
2. Negative exponent of the rational exponent makes the radical notation a negative value
3. Denominator of the radical exponent becomes the power of the radicand in the radical notation
4. Denominator of the rational exponent becomes the index of the radical notation
5. Numerator of the rational exponent becomes power of the radicand in the radical notation
Given:
Converting rational exponents to radical notation.
To find:
The correct statements.
Solution:
According to the property of exponents, conversion of rational exponents to radical notation is
[tex]x^{\frac{a}{b}}=\sqrt[b]{x^a}[/tex]
In [tex]x^\frac{a}{b},[/tex] x is base, a is numerator of the rational exponent and b is denominator of the rational exponent.
In [tex]\sqrt[b]{x^a}[/tex], x is radicand, a is power of radicand and b is index of radical notation.
Denominator of the rational exponent becomes the index of the radical notation.
Numerator of the rational exponent becomes power of the radicand in the radical notation.
Therefore, the correct options are 4 and 5.
Using the conversion of rational exponents to radical notation, it is found that the correct options are:
4. Denominator of the rational exponent becomes the index of the radical notation
5. Numerator of the rational exponent becomes power of the radicand in the radical notation
The conversion of rational exponents to radical notation is modeled by:
[tex]a^{\frac{n}{m}} = \sqrt[m]{a^n}[/tex]
That is:
The numerator becomes the power of the radicand, hence item 5 is correct.The denominator becomes the index of the radical notation, hence item 4 is correct.A negative exponent just is represented by a fraction, as [tex]a^{-\frac{n}{m}} = \frac{1}{a^{\frac{n}{m}}}[/tex], hence the radical is not negative, and item 2 is incorrect.

Brandi earned $140 from a summer job to buy new clothes for school. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found two pairs of shorts for $25 each and four shirts with an average cost of $19 per shirt. She will have to pay 7.5% sales tax.
Answer:
She will pay a tax of $9.45
Step-by-step explanation:
The question doesn't seem complete, but since we are given her tax rate, then they would surely ask for the amount of tax she paid. So let's work on this.
We are told that she bought two pairs of shorts and one short goes for $25 each, this implies that she will get the two for:
= $25 × 2
= $50
We are also told that she got four shirts that have an average cost of $19 per shirt. This implies that she will get the four shirt for:
= $19 × 4
= $76
Since she will have to pay a tax of 7.5%, then we will calculate it as:
= 7.5% × ($50 + $76)
= 0.075 × $126
= $9.45
Answer:
A. $9.45
B. Total cost = $135.45
Step-by-step explanation:
PART A: If she buys all of the items, how much sales tax will she have to pay?
The sales tax for Brandi's purchase will be $(insert answer here)
PART B: What is the total cost of her purchase including sales tax?
Brandi will spend $(insert answer here) on her purchases, including sales tax.
A.
Total amount earned = $140
Two pairs of shorts = $25 each
Total cost of 2 shorts = 2 shorts × $25 each
= $50
Four shirts = $19 each
Total cost of 4 shirts = 4 × $19
= $76
Amount of Sales tax = 7.5% of Total cost of 2 shorts + Total cost of 4 shirts
= 7.5% ($50 + $76)
= 0.075 × 126
= $9.45
Total cost = Total cost of 2 shorts + Total cost of 4 shirts + Amount of Sales tax
= $50 + $76 + $9.45
= $135.45
Therefore, she has enough money to buy all the items she likes

B) y = a-x + 1
C) y = a-x + 2
D) y = a-x + 3
Answer:a
Step-by-step explanation:
The solution is:
The initial value of the function is 2
The base of the function is 3
The function shows exponential growth
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
f(x) = 2(3^x)
Exponential functions are those with the following equation:
y = a*b^x
where a ≠ 0, b > 0 and b ≠ 1 and x is a real number.
a is the y-intercept and b is the base.
The initial value of the function is the same as the y-intercept
If a is positive, the function growth. If a is negative, the function decay
Hence, The initial value of the function is 2
The base of the function is 3
The function shows exponential growth

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases in quadrant 1. The equation of the function is y = f (x). The function crosses the y-axis at (0, 2).

Consider these functions: f(x)= -2x - 1 g(x)= -1/2x + 1/2 Which statements, if any, are true about these functions? I. The function f(g(x)) = x for all real x. II. The function g(f(x)) = x for all real x. III. Functions f and g are inverse functions. A. I only B. II only C. I, II, and III D. None of the statements are true.
Answer:
A. I only
Step-by-step explanation:
Given the functions
h(x)= -2x - 1 g(x)= -1/2x + 1/2
h(g(x) =h( -1/2x + 1/2)
=f((-x+1)/2)
We are to replace x in h(x) with -x+1/2
h((-x+1)/2) = -2(-x+1)/2 + 1
h((-x+1)/2) = -(-x+1)+1
h((-x+1)/2)= x-1+1
h((-x+1)/2) = x
h(g(x) = x
Also for g(h(x))
g(h(x)) = g(-2x-1)
Since g(x) = -x+1/2
g(-2x-1) = -(-2x-1)+1/2
g(-2x-1) =2x+1+1/2
g(-2x-1) = 2x+2/2
g(-2x-1) = 2(x+1)/2
g(-2x-1) = x+1
Sine g(h(x)) ≠ h(g(x)), hence both functions are not inverses of each other
Hence I. The function h(g(x)) = x is the only correct option. Option A is correct
The correct option is: A. I only
We have functions:
[tex]h(x)= -2x - 1 \\g(x)= -\frac{1}{2} x +\frac{1}{2} \\h(g(x)) =h(-\frac{1}{2} x +\frac{1}{2}) \\h(g(x))=f(\frac{-x+1}{2} )[/tex]
Now, replace x in h(x) by [tex]\frac{-x+1}{2}[/tex]
So,
[tex]h(\frac{-x+1}{2} ) = -2(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} ) = -(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} )= x-1+1\\h(\frac{-x+1}{2} )=x\\h(g(x)) = x[/tex]
Now, g(h(x))
g(h(x)) = g(-2x-1)
Since [tex]g(x) = \frac{-x+1}{2}[/tex]
[tex]g(-2x-1) = \frac{-(-2x-1)+1}{2} \\g(-2x-1) =\frac{2x+1+1}{2}\\g(-2x-1) =\frac{2x+2}{2}\\g(-2x-1) = x+1[/tex]
As g(h(x)) ≠ h(g(x)),
Therefore, both functions are not inverses of each other.
Hence A. I only
The function h(g(x)) = x is the only correct option.
So, option A is correct.
