Final answer:

The maximum number of concrete blocks that the elevator can lift is 107.

Explanation:

To find the maximum number of concrete blocks that the elevator can lift, we need to divide the maximum weight the elevator can lift by the weight of each concrete block.

Maximum weight the elevator can lift = 4400 lbs
Weight of each concrete block = 41 lbs

Now, we can use the division operation to find the maximum number of concrete blocks:

Maximum number of concrete blocks = 4400 lbs ÷ 41 lbs ≈ 107.317

Since we cannot have a fraction of a concrete block, we can conclude that the maximum number of concrete blocks that the elevator can lift is 107.

Answer:

(4, -6)

4x + y = 10

4x + (-6) = 10

4x - 6 = 10

4x = 16

x = 4

Outbound Trip 120 miles 60 mph equals 2 hours

Return Trip 120 miles

Total Trip 240 miles at 45 mph average speed

Total time = distance / rate = 240 / 45 = 5.3333333333 Hours

The return trip of 120 miles takes (5.3333333333 Hours MINUS 2 hours)

Return Trip Speed = 120 / 3.333333333 = 36 miles per hour

The car's speed on its return trip from B to A was approximately 36mph, based on the given average round trip speed and the speed of the trip from A to B.

The subject of this question is the calculation of an unknown speed during a return trip. Let's first calculate the total time of the round trip. The time taken to journey from A to B (we'll call this 'Time1') can be calculated by distance/speed, which equals 120 miles / 60mph, and that equals 2 hours.

The total round trip time (we'll call this 'Total Time') can be calculated by distance/speed, which equals 240 miles / 45mph, and that equals roughly 5.33 hours.

The time taken to return from B to A (we'll call this 'Time2') is the difference between 'Total Time' and 'Time1', which equals roughly 5.33 hours - 2 hours, equaling 3.33 hours.

The speed on the return trip ('Speed2') is the distance divided by Time2, so 120 miles / 3.33 hours equals approximately 36 miles per hour.

x-intercept (48,0)

y intercept(0,6)

Let every line = 1 unit:

Point C is located at (0,0)

Point D is located at (7, 12)

The slope is the change in Y over the change in X:

Slope = 12-0 / 7-0 =  12/7

The equation of the line from C to D using mx +b:

m = slope, which we already calculated as 12/7

To solve for b, replace m with 12/7 to get

y=12/7x +b

replace x with 0 ( from point C )

y = 12/7(0) +b

Replace y with 0 (also from point C)

0 = 12/7(0)+b

Solve for b:

b = 0

The equation becomes y= 12/7x

The Domain is the X values, which range from A to E, -12 to 13

Which is written as (-12,13) or -12≤x≤13

The range is the Y values, which range from A to D, 0 , 12

Which is written as (0,12) or 0≤y≤12

This is a pemdas problem. The basic rule of pemdas is:

Multiplication/division and addition/subtraction are in no particular order; they are solved from left to right.

Since you solve inside the parentheses first, you would first add 1 and 2 together and then rewrite the problem.

6 ÷ 2(3)

Now you have 6 divided by 2 multiplied by 3. Pemdas shows that division and multiplication are solved in no particular order, so that means that you will solve this expression from left to right.

Start by dividing 6 and 2, then rewrite the problem.

3(3) is what you are left with.

Multiply 3 and 3 together and you will be left with your final answer of:

Final answer:

To find the cost of four tickets for each route, multiply the price matrix [150 160 180] by the matrix [4], giving [600 640 720] as the cost matrix for four tickets to Chicago, Boston, and Dallas respectively.

Explanation:

To find the cost of four tickets for each of the three routes from Atlanta (Chicago, Boston, and Dallas), we need to multiply the given matrix representing the prices of each route by a matrix that contains the number of tickets for each route. The cost matrix for one ticket is [150 160 180]. To calculate the cost for four tickets, we can multiply this matrix by a column matrix that has the value 4 for each route since we want to buy four tickets for each destination.

The column matrix will thus be [4] since we only have one column (for the number of tickets) and three rows (one for each destination). The multiplication process is straightforward:

[150 160 180] x [4] = [600 640 720]

So, the matrix representing the cost of four tickets to each destination is: [600 640 720].

The correct answer is (2,−1)

The goal is to raise AT LEAST $180, so this automatically indicates that the amount of keychains sold with the price must be the same or more than $180.

k = number of keychains

each keychain is $2.25

2.25k ≥ 180

divide both sides by 2.25 to get the k alone

k ≥ 80

The answer is 2.25k ≥ 180, k ≥ 80

Step-by-step explanation:

  From the graph attached, Options (1) and (3) represent the correct points (local minimum and global maximum).

    If there are multiple peaks and troughs in the graph of a function, highest peak will be the global maximum and lowest point will be the global minimum.

 From the graph attached,

(4, 4) is the highest but the lowest point is in the infinity.

Therefore, (4, 4) will be the global maximum and no global minimum.

Other point in the trough (-2, -2) will be local minimum and the points on  peaks (0, 2) and (-4, 3) will be local maximum.

One way is to create a factor tree for each number.  Then see which factors they have in common.

Example:

   12                30

   ^                  ^

2    6             3  10

      ^                   ^

    2  3               2  5

The factors are the underlined numbers above:

12: 2 x 2 x 3

30: 2 x 3 x 5

The common factors are: 2, 3, and 6    why 6? because 2 x 3 = 6

The greatest common factor is: 6

To find the common factors and the greatest common factor (GCF) of numbers, list all factors of each number, find the common ones, and identify the largest as the GCF. The factor-label method can simplify locating the GCF.

To find the common factors and the greatest common factor (GCF) of two numbers, you start by listing all the factors of each number. These are whole numbers that can divide the numbers without a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, and the factors of 18 are 1, 2, 3, 6, 9, and 18.

Common factors are factors that the two numbers share. In our example, the common factors of 12 and 18 are 1, 2, 3, and 6.

The greatest common factor (GCF) is the largest of these common factors. This helps in multiplication and division of numbers, particularly when simplifying fractions. Here, the GCF of 12 and 18 is 6.

To find the GCF more quickly, you can use the factor-label method. Divide both numbers by a common factor and continue this process with the resulting numbers until you can't find any common factors other than 1. The GCF is the product of all the common factors you used to divide.

Set up a proportion like 64/x = 80/100 and solve for x. x=80

Final answer:

Explaining how to write and solve the equation to find 80% of 64.

Explanation:

Write the equation: 64 = 0.80x, where x represents the unknown value.

Solve for x: Divide both sides by 0.80 to isolate x. x = 64 / 0.80 = 80, so 64 is 80% of 80.

Answer: 64 is 80% of 80.

Triangles ΔWXY and ΔWVZ are similar because they are both isosceles with two pairs of congruent angles and a shared vertex angle, which satisfies the AA similarity criterion.

To prove that triangles ΔWXY and ΔWVZ are similar, we need to establish that they have the same angle measures and their sides are proportional. Since we know ΔWXY and ΔWVZ are both isosceles triangles, they have two angles of equal measure. Specifically, the base angles of an isosceles triangle are congruent, therefore in ΔWXY, angles WYX and WXV are equal, and in ΔWVZ, angles WZV and WVZ are equal.

We also know that these triangles share the vertex angle at W, which means ΔWXY and ΔWVZ both have the angle W in common. This establishes that all corresponding angles between ΔWXY and ΔWVZ are congruent. Since both triangles are isosceles and have two pairs of congruent angles (base angles) and a common vertex angle, they are similar by the AA (Angle-Angle) similarity criterion. The ratio of the sides opposite the equal angles in isosceles triangles should be constant, thereby confirming the similarity.
