Answer:
48
Step-by-step explanation:
We must first find what is 75% of 64 (x), in order to find what this number is 120% of (y).
To find percentages, we can use the formula[tex]\frac{is}{of}=\frac{p percent}{100}[/tex], and we cross multiply and divide to find either the is value, of value, or the percent.
Thus, we have[tex]\frac{x}{64}=\frac{75}{100}\\ \\ 100x=(64*75)\\\\\frac{(100x=(64*75))}{100} \\\\x=48[/tex]
Now we want to find what 48 is 120% of:
[tex]\frac{48}{y}=\frac{120}{100} \\\\ 120y=(48*100)\\\\[/tex]
[tex]\frac{(120y=(48*100)}{120} \\\\y=40[/tex]

angle 0 is in quadrant I with cos 0 is 10/17. which of the following would be the appropriate step in calculating the value of sin 0 using the pythagorean identity?
a. sin 0 + (10/17)^2 = 1
b. sin 0 - (10/17)^2 = 1
c. sin^2 0 + (10/17)^2 = 1
d. sin^2 0 - (10/17)^2 = 1
Work Shown:
[tex]\sin^2(\theta) + \cos^2(\theta) = 1\\\\\sin^2(\theta) + \left(\cos(\theta)\right)^2 = 1\\\\\sin^2(\theta) + \left(\frac{10}{17}\right)^2 = 1[/tex]
As the name implies, the pythagorean identity uses the pythagorean theorem for right triangles. The 1 on the right hand side is the length of the hypotenuse, which is the radius of the unit circle.

Write a polynomial of degree 3 whose only roots are x=2 and x=2/5. Is there another polynomial of degree 3 that has the same roots?
Answer:
Step-by-step explanation:
(x - 2)² (x - 2/5) = 0
5(x - 2)² (x - 2/5) = 0
(x - 2)² * 5(x - 2/5) = 0
(x - 2)² (5x - 2) = 0
(x² - 4x + 4)(5x - 2) = 0
5x³ - 20x² + 20x - 2x² + 8x - 8 = 0
5x³ - 22x² + 28x - 8 = 0
Another possible polynomial is
(x - 2) (x - 2/5)² = 0

1.) 10 + 8 ÷ 2 ( 4 + 3 )
2.) 21 ÷ ( 1 ) ( 3 ) + 0 - 14
Answer:
1) 38
2) 49
Step-by-step explanation:
1) 10 + 8 ÷2（4 + 3）
Knowing Pemdas, we do the expression in the parentheses first.
4+3 = 7
The new expression is: 10 + 8 ÷ 2 · 7
Using Pemdas, 8 ÷ 2 is 4.
10 + 4 · 7
10 + 28 = 38.
The answer to #1 is 38.
2) 21 ÷ ( 1 ) ( 3 ) + 0 - 14
21 ÷ 1 = 21
21 · 3 = 63
63 + 0 = 63
63 - 14 = 49
The answer to #2 is 49.
From a survey of 100 college students, a marketing research company found that 55 students owned iPods, 25 owned cars, and 5 owned both cars and iPods.
How many students do not own either a car or an iPod?
Answer:
Correct option is B)
n(AUB)=n(A)+n(B)−n(A∩B)
=75+45−35
=85
number of students owing car or stereos=85
number of students neither car nor stereo =100−85=15
The number of students who do not own either a car or an iPod is 25.
What is union of sets?Union of two given sets is the smallest set which contains all the elements of both the sets.
What is intersection of sets?Intersection of two given sets is the largest set which contains all the elements that are common to both the sets
What is the formula for union of two sets?The union of two sets is given by
n(A∪B) = n(A) + n(B) -n(A∩B)
Where,
A and B are the two sets.
∪ is the union
∩ is the intersection.
According to the given question.
Total number of students in a college = 100
Total number of students who own iPods, n(A) = 55
Total number of students who own cars, n(B) = 25
Number of students who own both cars and iPods, n(A∩B) = 5
Therefore,
The number of students who own cars or iPods is given by
n(A∪B) = n(A) + n(B) - n(A∩B)
⇒n(A∩B) = 55 + 25 - 5
⇒ n(A∪B) = 75
So, the number of students who do not own either a car or an iPod
= 100 - 75
= 25
Hence, the number of students who do not own either a car or an iPod is 25.

Answer:
The interval of decrease is 0 ≤ x ≤ 1.25
Step-by-step explanation:
First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.
The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.
We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation
d(1.25) = 40|1.25 - 1.25| = 0
We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.
We also see that there is no increase before 1.25, so we can make the interval begin at 0
A student is preparing to enroll in a private college in 3 years. The first year of tuition will cost $4,500. What is the minimum amount the student will need to save every month in order to pay for the first year of tuition?
A) $125 6
B) $1,500
C) $375
D) $29
The minimum amount the students are A) $125 will need to save every month in order to pay for the first year of tuition.
What are the minimum students?
Assuming that the student will save the same amount every month for three years to cover the first year of tuition, we need to find the monthly savings needed to accumulate $4,500 in 36 months.
$4,500 ÷ 36 months = $125
Therefore, the student needs to save $125 every month to pay for the first year of tuition in three years.
So, the answer is A) $125.

A quantity with an initial value of 3700 decays exponentially at a rate of 6% every 5
minutes. What is the value of the quantity after 36 minutes, to the nearest
hundredth?
Answer:
2369.86
Step-by-step explanation:
f(36)=3700(1−0.06) ^36/5
2369.857704098921
The value of the quantity after 36 minutes is approximately 3701.5.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We can use the formula for exponential decay to find the value of the quantity after 36 minutes:
[tex]A =A_{0} e^-^r^t[/tex]
where:
A₀ = initial value = 3700
r = decay rate per unit time = 6% = 0.06
t = time in minutes
We want to find A after 36 minutes, so:
t = 36
Substituting these values into the formula, we get:
[tex]A = 3700e^(^-^0^.^0^6^\times^ 3^6^/^5)[/tex]
A=3701.5
Therefore, the value of the quantity after 36 minutes is approximately 3701.5.

PA or B)?
A. 0.75
B. 0.22
C. 0.12
D. 0.70
By mutually exclusive, it means that there are no overlaps between the two events. This means that the probability of the P(A U B) or P(A or B) is simply the sum of the two probabilities.
P(A or B) = 0.40+0.30=0.70
Therefore the answer would be D 0.70

A rectangle with a perimeter of 78 millimeters has a length and width in a ratio of 9:4. What are the length and width?
Answer:
Step-by-step explanation:
Let the length be 9x, then the width is 4x
perimeter = 2(9x + 4x) = 2(13x) = 26x = 78, so x = 78/26 = 3
So
the length = 9x = 9(3) = 27 mm
the width = 4x = 4*3 = 12 mm.
