To determine the number of small boxes and large boxes shipped, we can set up a system of equations and solve for the variables. In this case, we have two equations based on the total weight and the total number of boxes. By using the elimination method, we can find that 10 small boxes and 12 large boxes were shipped.

To solve this problem, we can set up a system of equations. Let's denote the number of small boxes as x and the number of large boxes as y. We can then write two equations based on the information given:

45x + 75y = 1350 (equation 1)   (since the total weight is 1350 pounds)

x + y = 22 (equation 2)   (since the total number of boxes is 22)

We can solve this system of equations by either substitution or elimination method. Let's use the elimination method. Multiply equation 2 by 45 to make the coefficients of x in both equations equal:

45x + 45y = 990 (equation 3)

Now, subtract equation 3 from equation 1:

45x + 75y - (45x + 45y) = 1350 - 990

30y = 360

y = 12

Substitute the value of y back into equation 2:

x + 12 = 22

x = 10

Therefore, the number of small boxes shipped is 10 and the number of large boxes shipped is 12.

Pam shipped 10 small boxes and 12 large boxes of paper.

Let's denote:

- x : Number of small boxes of paper.

- y : Number of large boxes of paper.

1. Total number of boxes shipped:

x + y = 22

2. Total weight of the shipment:

[tex]\[ 45x + 75y = 1350 \][/tex]

Now, let's solve these equations step-by-step.

Solve for  x + y = 22

From equation (1):

[tex]\[ x + y = 22 \]\[ y = 22 - x \][/tex]

Substitute  y = 22 - x  into equation (2)

Substitute  y = 22 - x  into equation (2):

[tex]\[ 45x + 75(22 - x) = 1350 \][/tex]

Expand and simplify:

[tex]\[ 45x + 1650 - 75x = 1350 \]\[ -30x + 1650 = 1350 \][/tex]

Solve for x

Subtract 1650 from both sides:

[tex]\[ -30x = 1350 - 1650 \]\[ -30x = -300 \][/tex]

Divide both sides by -30:

[tex]\[ x = \frac{-300}{-30} \]\[ x = 10 \][/tex]

Find y

Now that we have ( x = 10 ), substitute back into ( y = 22 - x ):

[tex]\[ y = 22 - 10 \]\[ y = 12 \][/tex]

- Number of small boxes: 10

- Number of large boxes: 12

Check the total weight:

[tex]\[ 45 \times 10 + 75 \times 12 = 450 + 900 = 1350 \text{ pounds} \][/tex]

This matches the given total weight of 1350 pounds, confirming that our solution is correct.

Answer:

option c

Step-by-step explanation:

The object reaches -200 degrees C at 15 hrs, coldest temperature it ever achieved

Answer:

The correct option is C.

Step-by-step explanation:

It is given that the temperature of the material in degrees Celsius, y, can be modeled by the following graph, where x represents the time, in hours.

From the given graph it is clear that  

1. The y-intercept is 40, so the initial temperature is 40 degree Celsius.

2.The vertex of the upward parabola is at (15,-200), so material's temperature reaches a minimum -200 degrees Celsius at 15 hours.

3. The material return to its initial temperature after 30 hours because the temperature is 40 degree Celsius at x=30.

Therefore the correct option is C.

Answer:

acceleration

Step-by-step explanation:

In a speed-time graph, the speed data is on the Y-axis and the time is represented on the X-axis.

A slope is the variation of Y-values over the variation of the X-values between to points.

So, the slope of a speed-time graph would be the variation of the speed over the variation of time.

Let's say your units are m/s for the speed and s for the time.

The slope units would then be calculated by dividing m/s by s... (m/s) / s....

That would give you m/s², which is an acceleration unit.

Answer:

Answer: 76 child tickets were sold that day.

Step-by-step explanation:

You need to set up a system of equations.

Let be "c" the number of child tickets sold that Wednesday and "a" the number of adult tickets sold that Wednesday.

Then:

[tex]\left \{ {{a+c=173} \atop {9.40a+5.70c=1345.0}} \right.[/tex]

Using the Method of Elimination, you can multiply the first equation by -9.40, then add both equations and finally solve for "c":

Answer:

the answer is C 0.75 to 1.0

Over the intervals 0.25 to 0.5, 0.5 to 0.75, and 0.75 to 1.0, the exponential and linear functions are approximately equal.

To determine over which interval the exponential and linear functions are approximately the same, we first need to define the functions. Let's denote the exponential function as [tex]\( f(x) = e^x \)[/tex] and the linear function as ( g(x) = mx + c ), where ( m ) is the slope and ( c ) is the y-intercept.

Given the intervals, we'll first need to calculate the values of the exponential function at the endpoints of each interval and then find the linear function that best approximates those values. We'll choose the linear function with the same value at the starting point of each interval and approximate the slope ( m ) based on the difference in the exponential function values at the endpoints of the interval.

Let's start with each interval:

1. Interval from 0.25 to 0.5:

  - Endpoint 1:[tex]\( f(0.25) = e^{0.25} \approx 1.284 \)[/tex]

  - Endpoint 2: [tex]\( f(0.5) = e^{0.5} \approx 1.649 \)[/tex]

  - Approximating a linear function starting at ( f(0.25) ):

  [tex]- \( m = \frac{f(0.5) - f(0.25)}{0.5 - 0.25} = \frac{1.649 - 1.284}{0.5 - 0.25} \approx 0.73 \)[/tex]

[tex]- \( c = f(0.25) \approx 1.284 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 0.73x + 1.284 \)[/tex]

2. Interval from 0.5 to 0.75:

  - Endpoint 1:[tex]\( f(0.5) = e^{0.5} \approx 1.649 \)[/tex]

  - Endpoint 2: [tex]\( f(0.75) = e^{0.75} \approx 2.117 \)[/tex]

  - Approximating a linear function starting at ( f(0.5) ):

  [tex]- \( m = \frac{f(0.75) - f(0.5)}{0.75 - 0.5} = \frac{2.117 - 1.649}{0.75 - 0.5} \approx 0.934 \)[/tex]

 [tex]- \( c = f(0.5) \approx 1.649 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 0.934x + 1.649 \)[/tex]

3. Interval from 0.75 to 1.0:

  - Endpoint 1: [tex]\( f(0.75) = e^{0.75} \approx 2.117 \)[/tex]

  - Endpoint 2: [tex]\( f(1.0) = e^{1.0} \approx 2.718 \)[/tex]

  - Approximating a linear function starting at ( f(0.75) ):

 [tex]- \( m = \frac{f(1.0) - f(0.75)}{1.0 - 0.75} = \frac{2.718 - 2.117}{1.0 - 0.75} \approx 1.202 \)[/tex]

 [tex]- \( c = f(0.75) \approx 2.117 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 1.202x + 2.117 \)[/tex]

4. Interval from 1.25 to 1.5:

  - Endpoint 1:[tex]\( f(1.25) = e^{1.25} \approx 3.490 \)[/tex]

  - Endpoint 2: [tex]\( f(1.5) = e^{1.5} \approx 4.482 \)[/tex]

  - Approximating a linear function starting at ( f(1.25) ):

   [tex]- \( m = \frac{f(1.5) - f(1.25)}{1.5 - 1.25} = \frac{4.482 - 3.490}{1.5 - 1.25} \approx 3.946 \)[/tex]

    - [tex]\( c = f(1.25) \approx 3.490 \)[/tex]

    - So, the linear function is[tex]\( g(x) \approx 3.946x + 3.490 \)[/tex]

Now, we can compare each linear approximation to the exponential function within its respective interval:

1. For the interval from 0.25 to 0.5, the linear function [tex]( g(x) \approx 0.73x + 1.284 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

2. For the interval from 0.5 to 0.75, the linear function[tex]\( g(x) \approx 0.934x + 1.649 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

3. For the interval from 0.75 to 1.0, the linear function [tex]\( g(x) \approx 1.202x + 2.117 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

4. For the interval from 1.25 to 1.5, the linear function [tex]\( g(x) \approx 3.946x + 3.490 \)[/tex] is not approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

So, the exponential and linear functions are approximately the same over the intervals from 0.25 to 0.5, 0.5 to 0.75, and 0.75 to 1.0.

Answer:

23%

Step-by-step explanation:

156 / 678 * 100 = 23%

The correct answer is 23%

Final answer:

Joshua brought about 23% of his LEGOs to Emily's house, which is calculated by dividing 156 (the number of LEGOs he brought) by 678 (the total number he owns) and then multiplying by 100.

Explanation:

To find what percentage of LEGOs Joshua brought to Emily's house, you divide the number of LEGOs Joshua brought by the total number of LEGOs he owns and then multiply the result by 100.

The formula to find the percentage is:

(Number of items of interest ÷ Total number of items) × 100 = Percentage

So in this case, it would be:

(156 ÷ 678) × 100

First, you perform the division:

156 ÷ 678 = 0.23 (rounded to two decimal places)

Then multiply by 100 to find the percentage:

0.23 × 100 = 23%

Therefore, Joshua brought about 23% of his LEGOs to Emily's house.
