Select the pairs that have a GCF of 3

Answer: A- she can not mow 1 and 1/4 in an hour.

Step-by-step explanation:

set up a ratio

\(\frac{.5}{25} =\frac{x}{60}\) (1/2 acre is 25 minutes, x acre in 60 minutes)

cross multiply to solve

.5(60)=25x

30=25x

1.2=x- she can mow 1.2 acres in 60 minutes, 1.2= \(1\frac{1}{5}\)

Step 1: Pick any two points

The points are represented as (x1,y1), (x2,y2).

where x1= -4, y1= -8, x2= 0, y2= 4

Step 2: Write out the formula of the equation to use

Step 3: Substituting the values and to get the equation

The equation that represents the graph is y= 3x+4.

Option A is the correct answer.

Answer:

The % of drivers that will exceed this limit is 10.56 %

Step-by-step explanation:

Let's start defining the random variable :

\(X\) : '' The speed on that road ''

We know that \(X\) can be modeled with a Gaussian distribution ⇒

\(X\) ~ \(N\) ( μ , σ )

Where ''μ'' is the mean and ''σ'' is the standard deviation. Given that the average speed and the standard deviation of the problem are known we write :  

\(X\) ~ \(N(67,4)\)

We are asked about \(P(X>72)\) (which is the % of drivers that will exceed this limit).

To find this probability we are going to make a standardization of the variable \(X\) (also called a change of variables).

We are going to substract the mean to \(X\) and then divide by its standard deviation :

\(P(X>72)=\) P [(X-μ) / σ > (72 - μ) / σ] (I)

The new variable [(X - μ) / σ] is called Z.

Z can be modeled as

\(Z\) ~ \(N(0,1)\)

⇒ Replacing in (I) the values of the mean and the standard deviation :

\(P(Z>\frac{72-67}{4})\) = \(P(Z>1.25)=1-P(Z\leq 1.25)\)

The convenience of this is that we can find the probabilities of Z (which is a N(0,1) ) in any table on internet ⇒

Looking at any table we will find that \(P(Z\leq 1.25)=0.8944\) ⇒

\(P(X>72)=P(Z>1.25)=1-P(Z\leq 1.25)=1-0.8944=0.1056\) = 10.56 %

We find that the % of drivers that will exceed this limits is 10.56 %

Answer:

  EF = 13.1

  FD = 35.3

Step-by-step explanation:

The distance between two points on a number line is the positive difference between their coordinates.

EF = F - E = 19 -5.9

EF = 13.1

__

FD = F - D = 19 -(-16.3) = 19 +16.3

FD = 35.3

A. True

Answer:

Step-by-step explanation:

1. use distribution factor

(4x+3)(24+5x)

4x times 24 = 96

4x times 5x = 20x

3 times 24 = 72

3 times 5x = 15x

2. combine like terms

96 + 72 = 168

15x + 20x = 35x

35x + 168 or 168 + 35x

If the acceleration of the object becomes 9m/s², the force will be 24N

From the information, the moving object, the force acting on the object varies directly with the object's acceleration. When a force of 36N acts on a certain object, the acceleration of the object is 6m/s². The constant will be:

y = k/x

y = force.

x = acceleration

k = constant of proportionality.

k = 36 × 6

k = 216

If the acceleration of the object becomes 9m/s², the force will be:

= 216 / 9

= 24

The force is 24N.

Answer: I cannot see the entire question for two of them, however angle 6 is 84 degrees and angle 5 is 96 degrees.

Step-by-step explanation:

Parallel lines crossed by a transversal form special pairs of angles. Angle 84 is vertical to angle 2. Vertical angles are equal. Angle 2 is also 84. Angle 84 and angle 4 are corresponding angles. They are equal, so angle 4 is 84. Angles 4 and 6 are vertical angles. Vertical angles are equal. This means angle 6 is also 84. Now for the rest of the missing angles. Linear pairs of angles are supplementary (sum to 180). 84 and angle 1 are a linear pair. We know they have to sum to 180. 180 - 84= 96. Angle 1 is 96. If angle 1 is 96, then we know that angle 3 is 96 because they are vertical angles. If angle 3 is 96 then we know angle 7 is 96 because they are corresponding angles. And finally angle 5 is 96 because it’s vertical to angle 7. ( there are many different ways to solve this ex: linear pairs sum to 180,

Same side interior angles sum to 180, same side exterior angles sum to 180. Alternate interior angles are equal, Alternate exterior angles are equal, corresponding angles are equal, vertical angles are equal)

Answer:

29 day) $15.00

30 day $15.00

31 day $15.00

The cost was the same for all three days

Step-by-step explanation:

Rover = 3/4 can

Bobo = 1/2 can

29(3/4) + 29(1/2) = 21.75 + 14.5 = 36.25 cans

36.25/3 = 12.08

must buy 4 packs of 3 at $5.00 each = $15.00

30(3/4) + 30(1/2) = 22.5 + 15 = 37.5 cans

37.5/3 = 12.5

must buy 4 packs of 3 at $5.00 each = $15.00

31(3/4) + 31(1/2) = 23.25 + 15.5 = 38.75 cans

38.75/3 = 12.92

must buy 4 packs of 3 at $5.00 each = $15.00

We need to know the number of months Marian wants to save to get the specific value.

In the equation, we will need to calculate the maximum amount of money Marian can spend on the house.

We can calculate the maximum amount of money Marian can spend on a house by multiplying her monthly income by the number of months she would want to save.

Marian earns $4,100.00 per month

Suppose Marian wants  to save for  x months,  then the maximum amount that she can spend on the house is:

4100  *   x    +  21390

The answer is:  4100x  +  21390

Answer:

Step-by-step explanation:

The art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper for proper distribution.

To determine the largest number of identical kits the art teacher can make using all the crayons and drawing paper, we need to find the greatest common divisor (GCD) of the quantities.

The GCD represents the largest number that can divide all the quantities without leaving a remainder.

The GCD of the quantities of crayons can be found by considering the prime factorization:

72 = 2³ × 3²

48 = 2⁴ × 3

48 = 2⁴ × 3

48 = 2⁴ × 3

The GCD of the crayons is 2³ × 3 , which is 24.

Now, we need to find the GCD of the quantity of drawing paper:

120 = 2³ × 3 × 5

The GCD of the drawing paper is also 2³ × 3 , which is 24.

Since the GCD of both the crayons and drawing paper is 24, the art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper.

Each kit would contain an equal distribution of crayons and drawing paper.

The values of x is 6 and y is (-6).

An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself.

Given:

-4x-5y=6............(1)

9x+7y=12..................(2)

Solving Equation (1) and (2) we get

-36 x  - 45y = 54

36x + 28y = 48

____________

         -17y= 102

              y= -6.

and, -4x -5y= 6

-4x - 5(-6) = 6

Ms. Quarles has 120 tests in total and since each class has the same number of students, there are 30 students in each class.

In this problem, we are given that Ms. Quarles gave a math unit test to each of her four classes and that each class has the same number of students. Let's call the number of students in each class "x".

We are also given that Ms. Quarles grades 25% of the tests, which is 30 papers. This means that there are 30 papers that Ms. Quarles graded out of the total number of tests. We can set up an equation to represent this:

0.25x = 30

To solve for x, we can divide both sides of the equation by 0.25:

x = 30/0.25

x = 120

Therefore, there are 120 tests in total. Since each class has the same number of students, there are 120/4 = 30 students in each class.

Let's start by defining some variables:

Let's call Jamal's age "J".

Let's call Alex's age "A".

From the problem statement, we know that:

J = A - 5 (Jamal is 5 years younger than Alex)

J * A = 300 (the product of their ages is 300)

We can use the first equation to substitute J in the second equation:

(A - 5) * A = 300

Expanding the left-hand side:

A^2 - 5A = 300

Moving all terms to the left-hand side:

A^2 - 5A - 300 = 0

We can solve for A using the quadratic formula:

A = (-(-5) ± sqrt((-5)^2 - 41(-300))) / (2*1)

A = (5 ± sqrt(25 + 1200)) / 2

A = (5 ± sqrt(1225)) / 2

Since A is a positive integer, we take the positive solution:

A = (5 + 35) / 2 = 20

Now we can use the first equation to find J:

J = A - 5 = 20 - 5 = 15

Therefore, Jamal is 15 years old.
