what is common factors of 20 and 45?

Answers

Answer 1

The common factors of 20 and 45 are 1 and 5, since these are the only factors that both numbers share.

To find the common factors of two numbers, we need to find the factors of each number and then identify the ones that they have in common. For example, if we want to find the common factors of 20 and 45, we first find the factors of 20 and 45:

The factors of 20 are: 1, 2, 4, 5, 10, 20

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factor 1 is always a common factor of any two numbers, since every number is divisible by 1. The factor 5 is a common factor of 20 and 45 because both 20 and 45 are divisible by 5. It is important to note that the other factors of 20 and 45 are not common factors, since they are not shared by both numbers.

Therefore, the common factors of 20 and 45 are 1 and 5, since these are the only factors that both numbers share.

During the month of May, the sheriff's department issued 130 traffic tickets for speeding or failure to obey traffic signals. The fine for each speeding ticket
was $67.00, and each fine for failure to obey traffic signals was $67.00. The sheriff's department collected $8,710.00 in fines from these two offenses.
Which system of equations can be used to determine the number of speeding tickets given, x, and the number of tickets given for failure to obey traffic
signals, y?

Answers

Answer: The number of speeding tickets issued is represented by x and the number of tickets for failure to obey traffic signals is represented by y. The total number of tickets issued is 130, so we have:

x + y = 130

The total amount of money collected in fines is $8,710.00, so we have:

67x + 67y = 8710

These two equations form a system of linear equations that can be used to determine the number of speeding tickets, x, and the number of tickets for failure to obey traffic signals, y. To solve this system, we can use any of the methods for solving a system of linear equations, such as substitution, elimination, or matrices.

The population in a small town is increasing annually by 2.8%. What is the quarterly rate of population increase?

Answers

Answer:

To find the quarterly rate of population increase, we first need to find the annual rate of population increase in decimal form, which is 2.8% expressed as 0.028.

To find the quarterly rate, we need to divide the annual rate by 4, since there are 4 quarters in a year:

0.028 / 4 = 0.007

Therefore, the quarterly rate of population increase is 0.007 or 0.7%

While shopping after her birthday, Annie bought 2 pairs of jeans and 3 shirts and spent $127. Her twin sister Hallie bought the same items consisting of 1 pair of jeans and 4 shirts and spent $116 how much does one pair of jeans cost and how much does a shirt cost

Answers

Let's use variables to represent the cost of one pair of jeans and the cost of one shirt.

Let's use j for the cost of one pair of jeans and s for the cost of one shirt.

From the problem, we know that:

2j + 3s = 127 (Annie's purchase)
1j + 4s = 116 (Hallie's purchase)

We can use these two equations to solve for j and s. One way to do this is to use substitution. Solving one of the equations for one of the variables and then substituting that expression into the other equation, we get:

j = 116 - 4s (from the second equation)
2(116 - 4s) + 3s = 127 (substituting into the first equation)

Simplifying and solving for s, we get:

232 - 8s + 3s = 127

-5s = -105

s = 21

Now that we know the cost of one shirt is $21, we can substitute that value back into one of the equations to solve for j:

1j + 4(21) = 116

1j + 84 = 116

1j = 32

Therefore, one pair of jeans costs $32.

So, the cost of one pair of jeans is $32 and the cost of one shirt is $21.

Answer:

The shirt costs $21

Step-by-step explanation:

2x + 3y = 127    ....eq 1

Her twin sister Hallie bought 1 pair of jeans and 4 shirts for $116.

So, x + 4y = 116     ....eq 2

Multiplying eq 2 by 2, we get :

2x + 8y = 232     ....eq 3

Subtracting eq 1 by eq 3, we get :

(2x + 8y) - (2x + 3y) = 232 - 127

5y = 105

Thus, y = 21

Putting this value of y in eq 2, we get :

x + 4(21) = 116

x = 116 - 84 = 32

Therefore, the cost of a pair of jeans = x = $32

And the cost of a shirt = $21

Answers

The missing angle measures are:

m∠F = 22 degrees

m∠G = 75 degrees

m∠H = m∠C = 83 degrees

m∠C = 83 degrees

The angle measures

Since triangles ABC and FGH are similar, their corresponding angles are equal. Therefore:

m∠F = m∠A = 22 degrees

m∠G = m∠B = 75 degrees

m∠H = m∠C, since they are corresponding angles, but we still need to find the measure of m∠C.

To find m∠C, we can use the fact that the sum of the angles in a triangle is always 180 degrees. So:

m∠A + m∠B + m∠C = 180 degrees

Substituting the given values, we get:

22 degrees + 75 degrees + m∠C = 180 degrees

Simplifying, we get:

m∠C = 180 degrees - 22 degrees - 75 degrees = 83 degrees

Therefore, the missing angle measures are:

m∠F = 22 degrees

m∠G = 75 degrees

m∠H = m∠C = 83 degrees

m∠C = 83 degrees

Ann borrowed $8000 at a rate of 15%, compounded annually. Assuming she makes no payments, how much will she owe after 6 years?

Answers

Answer:

Ann will owe $15,258.23 after 6 years, assuming she makes no payments.

What is Compound Interest ?

Compound interest is a method of calculating interest on a loan or investment, where interest is earned on both the initial principal amount and on any interest that has already been earned. In other words, interest is added to the principal, and then interest is calculated on the new total amount (the principal plus the previously earned interest). This results in the interest earned growing exponentially over time.

According t o given condition :

To calculate the amount Ann will owe after 6 years, we can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

where:

A = the amount Ann will owe after 6 years

P = the initial principal amount borrowed, which is $8000 in this case

r = the annual interest rate as a decimal, which is 15% or 0.15

n = the number of times interest is compounded per year, which is once annually in this case

t = the number of years, which is 6 in this case

Plugging in these values, we get:

A =

A =

A = $15,258.23

Therefore, Ann will owe $15,258.23 after 6 years, assuming she makes no payments.

Complete the equation of the circle that includes the points (-5,4), (3,4), and (3,0)

The equation of circle is ( x + 1 )² + ( y - 2 )² = 20

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the points on the circle be A ( -5 , 4 ) , B ( 3 , 4 ) and C ( 3 , 0 )

Now , the equation of the circle is of the form

ax + by + c = x² + y²

Substituting the values in the equation , we get

-5a + 4b + c = 41   be equation (1)

3a + 4b + c = 25   be equation (2)

3a + c = 9   be equation (3)

Subtracting equation (2) from equation (1) , we get

-8a = 16   be equation (4)

Divide by -8 on both sides of the equation , we get

a = -2

Substitute the value of a in equation (3) , we get

3 ( -2 ) + c = 9

-6 + c = 9

c = 15

Substitute the value of a and c in equation (2) , we get

-6 + 4b + 15 = 25

4b + 9 = 25

4b = 16

b = 4

So , the value of a , b and c are -2 , 4 and 15 respectively

Now , the equation of circle will be

-2x + 4y + 15 = x² + y²

On simplifying the equation , we get

x² + y² + 2x - 4y - 15 = 0

( x² + 2x + 1 ) - 20 + ( y² - 4y + 4 ) = 0

So , the equation will be

( x + 1 )² + ( y - 2 )² = 20

Hence , the equation of circle is ( x + 1 )² + ( y - 2 )² = 20

So long as the abstract method is declared in a Class (not an Interface), there's nothing wrong with doing this5.

Acquiring Information Who does James Lawson"Indicate were the leaders of the sit in movement?What explanation does he give for the start of thesit-in movement? What information do we learn about Perry's past? Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card and B be the analogous event for MasterCard. Suppose that P(A) = 0.7 and P(B) = 0.4.A. Could it be the case that P(A B) = 0.5? Pick one:i. Yes, this is possible. Since B is contained in the event A B, it must be the case that P(B) P(A B) and 0.5 > 0.4 does not violate this requirement.ii. Yes, this is possible. Since A B is contained in the event B, it must be the case that P(B) P(A B) and 0.5 > 0.4 does not violate this requirement.iii. No, this is not possible. Since B is equal to A B, it must be the case that P(A B) = P(B). However 0.5 > 0.4 violates this requirement.iiii. No, this is not possible. Since B is contained in the event A B, it must be the case that P(A B) P(B). However 0.5 > 0.4 violates this requirement.v. No, this is not possible. Since A B is contained in the event B, it must be the case that P(A B) P(B). However 0.5 > 0.4 violates this requirement.B. From now on, suppose that P(A B) = 0.3. What is the probability that the selected student has at least one of these two types of cards?C. What is the probability that the selected student has neither type of card?D. In terms of A and B, the event that the selected student has a Visa card but not a MasterCard is A B' . Calculate the probability of this event.E. Calculate the probability that the selected student has exactly one of the two types of cards. Students collected data on five elements. Their data are shown in the table. Name.
