Problem 1

--------------------------

Explanation:

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

They are numbers that pair up to multiply to 20. For instance, 5*4 = 20. We only focus on whole numbers.

In the list given to us, we see that only 20 is a factor of 20. Something like 17 is not a factor of 20, and so on for the other values.

==========================================

Problem 2

--------------------------

Explanation:

List out the multiples of 3 to get {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...}

The stuff in bold are values found in the original list.

Now list out the multiples of 7 to get {7, 14, 21, 28, 35, 42, ...}

We can see that only 21 is found in both lists of multiples we wrote out.

Note how 3*7 = 21, which is not a coincidence.

A number's absolute value means the distance from 0. -6 is 6 units away from 0 units. The absolute value of -6, then, is 6. There's no negative distance you can have, so it has to be positive.

Answer:

a real number without regard to its sign.

Answer: 3/11

Step-by-step explanation:

Number of purple marbles = 6

Number of blue marbles = 5

Total number of marbles = 6 + 5 = 11

The probability of picking the dust purple marble will be 6/11. After a purple marvel has been picked, there'll be 5 purple marbles left and the total number of marbles will be 10, therefore the probability of picking the second purple marble will be 5/10.

Therefore we then multiply the probability of picking the first purple marble by the probability of picking the second purple marble. This will be:

= 6/11 × 5/10

= 6/11 × 1/2

= 3/11

Answer:

-0.0936538462

Step-by-step explanation:

Start by solving the right side of the equation

1 - 2.87 = -1.87

now we have:

3 + 5.2c = -1.87

subtract 3 from both sides to get:

5.2c = -4.87

divide both sides by 5.2 to get:

-0.0936538462

Answer:

The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].

The slope of the line graphed below would be 2.

Using the formula Rise/Run, you can solve the slope using the graph. The Rise would be equal to 2 units, with the Run being one. This means that for every 1 unit on the x-axis, there are 2 units displaced on the y-axis. Therefore, the slope would be 2/1.

Answer:

So, solving the equation [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex] we get [tex]9\frac{4}{5}[/tex]

Step-by-step explanation:

We need to solve the given equation: [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex]

First converting mixed fractions into improper fractions

[tex]\frac{7}{3} \times \frac{21}{5}[/tex]

Since 21 is divisible by 3 so, simplifying and multiplying

[tex]=7 \times \frac{7}{5} \\=\frac{49}{5} \\=9\frac{4}{5}[/tex]

So, solving the equation [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex] we get [tex]9\frac{4}{5}[/tex]

The centroid of a triangle is the point of intersection of its medians.

The lines that pass through the centroid of a triangle divides the side lengths of the triangle into equal halves.

The figure whose centroid is point G is triangle LMN.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, From the attached image, we have the following highlights

There is no evidence that the lines that pass through point G divides the three sides of triangle ABC into equal halves

The lines that pass through point G divides the three sides of triangle LMN into equal halves

The above highlights mean that:

Point G is the centroid of triangle LMN.

Hence, the figure whose centroid is point G is triangle LMN.

Answer:

The maximum weight of the second box is 125 pounds. (The box can weight  less than 125 pounds, but no more than 125 pounds since the total weight of the boxes cannot be more than 300 pounds.)

Step-by-step explanation:

x+y ≤ 300

175+y ≤ 300

Substract 175 on both sides:

y ≤ 125

The inequality that describes the weight limitation in terms of x and y is -

x + y ≤ 300 and the maximum weight of second box can be 125 pounds.

We have a conveyor belt such that there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds.

It is given in the question to assume let x and y represent the weights of the two boxes on the conveyer belt.

We have to find -

a) - inequality that describes the weight limitation in terms of x and y.

b) - If two boxes are to be placed on the conveyor belt and first box weighs 175 pounds then what is the maximum weight of the second box?

Inequality in mathematics is a relation that is used to compare two or more algebraic expressions.

According to the part 'a' of the question -

The inequality that describes the weight limitation in terms of x and y is -

x + y ≤ 300

According to part 'b' of the question -

x = 175 pounds

The maximum weight of second box can be found out by substituting the value of 'x' in inequality in part a.

175 + y ≤ 300

y ≤ 125

Hence, the maximum weight of second box can be 125 pounds.
