The surface area of the pyramid is 128.2cm².

What is the surface area of the pyramid?

A pyramid is a three-dimensional building with triangular lateral faces and a polygonal base. A pyramid's surface area is simply the total area of all of its faces.

Here, we have

Given:  A rectangular pyramid with a base of dimensions 7 centimeters by 5 centimeters. The two large triangular faces have a height of 7.6 centimeters. The two small triangular faces have a height of 8 centimeters.

We have to find the surface area of the pyramid.

The rectangular base of the pyramid has a length of 7 centimeters and a width of 5 centimeters, so the area of the rectangular base is 35 cm².

The two large triangular faces have a height of 7.6 centimeters, so the area of each of these faces can be calculated as:

= (1/2)×7×7.6

= 26.6 cm²

Similarly, the two small triangular faces have a height of 8 centimeters, so the area of each of these faces can be calculated as:

= (1/2)×5×8

= 20cm²

The total surface area of the rectangular pyramid is:

= 35cm² + 2×26.6 cm² + 2×20 cm²

= 128.2cm²

Hence, the surface area of the pyramid is 128.2cm².

The area of the forest after 13 years is  1990.08 [tex]km^2[/tex].

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b[tex])^x[/tex], where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

Here initial area a = 3500[tex]km^2[/tex] ,

Rate of decay = 4.25%= 4.25/100 = 0.0425

Now using exponential decay formula then,

=> [tex]y=a(1-b)^x[/tex] where x=13 years .

=> y = [tex]3500(1-0.0425)^{13}[/tex]

=> y = [tex]3500(0.9575)^{13}[/tex]

=> y = 1990.08 [tex]km^2[/tex]

Select the property of equality used to arrive at the conclusion. If x + 8 = 10, then x = 2. the multiplication property of equality the subtraction property of equality the division property of equality

Answers

The correct option- B. the subtraction property of equality is used to arrive at the conclusion. If x + 8 = 10, then x = 2.

Explain about the subtraction property of equality :

According to the equality's feature of subtraction, equality is unaffected when the same amount is subtracted from both sides of an equation.

If the exact same number or value is removed from both sides of an equation, the difference that results on both sides is also equal. Equal deductions from both sides of such an inequality will decrease the values on each side but have no effect on the inequality's truth value. In other words, the left side of a inequality will continue to be smaller than the right in a "less than" statement.

Given data:

x + 8 = 10

To find the value of x, subtract 8 from both sides:

x + 8 -8 = 10 - 8

x = 2

Thus, the subtraction property of equality is used to arrive at the conclusion. If x + 8 = 10, then x = 2.

help please. thank youu!!

Answers

To calculate percentages, we can use the following formula:

Percentage = (Part/Whole) x 100

Where "Part" is the value we are trying to find the percentage of and "Whole" is the total value.

Let's use this formula to solve the given problems:

1. 100% of 30
Percentage = (Part/Whole) x 100
Percentage = (30/30) x 100
Percentage = 100%

Therefore, 100% of 30 is 30.

2. 40% of 60
Percentage = (Part/Whole) x 100
Percentage = (40/100) x 60
Percentage = 24

Therefore, 40% of 60 is 24.

3. 20% of 80
Percentage = (Part/Whole) x 100
Percentage = (20/100) x 80
Percentage = 16

Therefore, 20% of 80 is 16.

4. 40% of 50
Percentage = (Part/Whole) x 100
Percentage = (40/100) x 50
Percentage = 20

Therefore, 40% of 50 is 20.

5. 80% of 20
Percentage = (Part/Whole) x 100
Percentage = (80/100) x 20
Percentage = 16

Therefore, 80% of 20 is 16.

6. 50% of 30
Percentage = (Part/Whole) x 100
Percentage = (50/100) x 30
Percentage = 15

Therefore, 50% of 30 is 15.

7. 60% of 80
Percentage = (Part/Whole) x 100
Percentage = (60/100) x 80
Percentage = 48

Therefore, 60% of 80 is 48.

8. 60% of 10
Percentage = (Part/Whole) x 100
Percentage = (60/100) x 10
Percentage = 6

Therefore, 60% of 10 is 6.

9. 90% of 70
Percentage = (Part/Whole) x 100
Percentage = (90/100) x 70
Percentage = 63

Therefore, 90% of 70 is 63.

10. 90% of 60
Percentage = (Part/Whole) x 100
Percentage = (90/100) x 60
Percentage = 54

Therefore, 90% of 60 is 54.

Sure, I'd be happy to help you calculate these percentages! Here are the solutions:

- 100% of 30 = 30

- 40% of 60 = 0.4 x 60 = 24

- 20% of 80 = 0.2 x 80 = 16

- 40% of 50 = 0.4 x 50 = 20

- 80% of 20 = 0.8 x 20 = 16

- 50% of 30 = 0.5 x 30 = 15

- 60% of 80 = 0.6 x 80 = 48

- 60% of 10 = 0.6 x 10 = 6

- 90% of 70 = 0.9 x 70 = 63

Round your answer to the nearest tenth, and do not round any intermediate computations.

Answers

It will take 2.48 hours for the number of bacteria to reach 3500.

How many hours to reach 3500?

In order to find number of hours to take for the number of bacteria to reach 3500, we can set the function equal to 3500 and solve for h.

The function given is P(h) = 2800e^(0.09h). So, plugging the values of 3500, we will get:

3500 = 2800e^(0.09h)

Dividing both sides by 2800, we get:

e^(0.09h) = 3500/2800

Taking the natural logarithm of both sides, we get:

0.09h = ln(3500/2800)

h = (ln(3500/2800))/0.09

h = 0.22314355131/0.09

b) $337.05

c) Nicole would pay more at the store

Step-by-step explanation:

a) 10% of $749 = $74.90

60% = ($74.90 x 6) = $449.40

$749 - $449.40 = $299.60

b) 10% = $74.90

50% = $374.50

$749 - $374.50 = $374.50

10% of $374.50 = $37.45

$374.50 - $37.45 = $337.05

abc is dilated by a scale factor of 4 with a center of dilation at the origin to form a’b’c’ then a’b’c’ is dilated by a scale factor of 3 over 4 with a center of dilation at the origin to create a’’b’’c’’ what are the coordinates of a’’b’’c’’

Answers

The coordinates of the vertices of the triangle A''B''C'' after the two successive dilations are (3 times the x-coordinate and 3 times the y-coordinate of the original triangle's vertices).

To find the coordinates of the vertices of the dilated triangle A''B''C'' after two successive dilations, first with a scale factor of 4 and then with a scale factor of 3/4.

Firstly, Apply the first dilation with a scale factor of 4 to the original triangle ABC, with a center of dilation at the origin. This can be done by multiplying each coordinate of the original triangle by 4.

The coordinates of the dilated triangle A'B'C' after the first dilation would be;

A' = (4 × x-coordinate of A, 4 × y-coordinate of A)

B' = (4 × x-coordinate of B, 4 × y-coordinate of B)

C' = (4 × x-coordinate of C, 4 × y-coordinate of C)

Now, we apply the second dilation with a scale factor of 3/4 to the dilated triangle A'B'C', again with a center of dilation at the origin. This can be done by multiplying each coordinate of A'B'C' by 3/4.

The coordinates of the dilated triangle A''B''C'' after the second dilation would be;

A'' = ((3/4) × x-coordinate of A', (3/4) × y-coordinate of A')

B'' = ((3/4) × x-coordinate of B', (3/4) × y-coordinate of B')

C'' = ((3/4) × x-coordinate of C', (3/4) × y-coordinate of C')

Plugging in the values of A', B', C' obtained from the first dilation, we get;

A'' = ((3/4) × 4 × x-coordinate of A, (3/4) × 4 × y-coordinate of A)

B'' = ((3/4) × 4 × x-coordinate of B, (3/4) × 4 × y-coordinate of B)

C'' = ((3/4) × 4 × x-coordinate of C, (3/4) × 4 × y-coordinate of C)

Simplifying further, we get;

A'' = (3 × x-coordinate of A, 3 × y-coordinate of A)

B'' = (3 × x-coordinate of B, 3 × y-coordinate of B)

C'' = (3 × x-coordinate of C, 3 × y-coordinate of C)

Therefore, the  coordinates of the vertices of the triangle A''B''C'' after the two successive dilations are (3 times the x-coordinate and 3 times the y-coordinate.

Kylie, a youth leader at a summer camp, is making clear slime for an activity with the kids. She is placing the slime in 2-ounce plastic containers with lids. If Kylie can mix up the slime and fill 75 containers in 50 minutes, how long will it take her to make the slime and fill up 450 of the 2-ounce plastic containers?

A. 6 hours
B. 5 hours
C. 4 hours
D. 9 hours

Answers

Therefore, the answer is (B) 5 hours. We can start by finding out how long it takes Kylie to fill one 2-ounce container. we can get by forming equation .

what is equation ?

In mathematics, an equation is a statement that two expressions are equal. An equation can contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and roots.

In the given question,

We can start by finding out how long it takes Kylie to fill one 2-ounce container. To do this, we can set up a proportion:

75 containers / 50 minutes = 1 container / x minutes

Solving for x, we get:

x = (50 minutes) / (75/1) = 0.67 minutes per container

Now we can use this information to find how long it will take Kylie to fill 450 containers:

450 containers × 0.67 minutes per container = 301.5 minutes

So it will take Kylie 301.5 minutes to make the slime and fill up 450 containers. We can convert this to hours by dividing by 60:

301.5 minutes / 60 minutes per hour = 5.025 hours

Rounding to the nearest hour, we get 5 hours.

Therefore, the answer is (B) 5 hours.

A psychology instructor surveys three sections of a first-year psychology course totaling 1000 students. The psychology instructor finds that SAT scores and the amount of money the students were currently carrying had a correlation of r=.07 with a p-value of 0.001. The psychology instructor claims the results were statistically significant but were not practically significant. Explain the difference between these two concepts using the results from the psychology instructor’s survey.

Answers

The concept of Statistical significance as well as practical significance are known to be two different concepts in statistics.

What is the differences in both concepts?

Statistical significance refers to unlikely results not due to chance. P-values are utilized for ascertaining the statistical importance of a particular result by gauging the likelihood of procuring exceptional outcomes under the assumption that the null hypothesis holds true. A significance level of 0.05 or less for the p-value is deemed as statistically meaningful.

Since the Psychology instructor found SAT scores and amount of money carried had a correlation coefficient of r = 0.07 with a p-value of 0.001, showing a significant correlation. The chance of getting a correlation coefficient of 0.07 or greater, if no correlation exists in the population, is very low.

A student ran out of time on a multiple choice exam and randomly guessed the answers for two problems. Each problem had 5 answer choices – a, b, c, d, e – and only one correct answer. What is the probability that she answered both of the problems correctly? Write your answer as a fraction in simplest form

Answers

The probability that the student, who ran out of time on a multiple choice exam and randomly guessed the answers for two problems, answered both of the problems correctly is ⁹/₂₅.

What is the probability?

Probability refers to the likelihood of an expected outcome occurring out of many possible outcomes.

Probability is computed as the quotient of expected outcome over total outcomes.

The number of questions left = 2

The number options of for each question = 5

Since there are 5 options for each question, 4 of which are wrong, the probability of getting both wrongs is:

⁴/₅ x ⁴/₅ = ¹⁶/₂₅ = 0.64 or 64%

Therefore, probability of getting both questions correct is 36% (1 - 64%) or ⁹/₂₅ (1 -  ¹⁶/₂₅).

The equation of the line is

Answers

Answer:

  y = -x +3

Step-by-step explanation:

You want the slope-intercept equation of the line with the same intercept as -3y = -9 +3x, and the same slope as -2x -2y = -8.

Slope-intercept form

The slope-intercept form of the equation of a line is ...

  y = mx +b . . . . . where m is the slope, and b is the y-intercept

For the given equations, we can put them in this form to find the desired parameters.

  -3y = -9 +3x

  y = -x +3 . . . . . . . . . . divide both sides by -3

We observe that the y-intercept is +3, which we will need for our answer.

The slope-intercept form of the second equation is ...

  -2x -2y = -8

  x + y = 4 . . . . . . . . . . divide by -2

  y = -x +4 . . . . . . . . . . subtract x

We observe that the slope (coefficient of x) is -1, which we will need for our answer.

Desired equation

We want the equation of the line with slope -1 and y-intercept 3. It is ...

  y = -x +3 . . . . . . . . . . same as the equation of the first line

__

Additional comment

The slope-intercept equation (green) is plotted using dots, so that you can see it is coincident with the line described by the first equation (red). Parallel lines have the same slope, so our desired line must be parallel to the blue line. (It is.)
