What is the value of a+b?

Answer: 13/50

Step-by-step explanation:

Angelica has to write a history paper on the founding of the 50

United States. Since Angelica is the first person to choose, the probability of choosing one of the first 13 States will be the 13 states divided by the total 50 states. This can be written as:

Probability= 13/50

The probability is therefore 13/50

Answer:

The dimensions of the bar are width = 4.68099 feet and length = 10.06198 feet

Step-by-step explanation:

A chocolate bar has a rectangular shape, therefore it's area is given by the following formula:

area = width*length

In this case the length is 0.7 feet longer than twice the width, therefore:

length = 2*width + 0.7

Applying the second equation on the first one and using the data from the question we have:

47.1 = width*(2*width + 0.7)

47.1 = 2*width² + 0.7*width

2*width² + 0.7*width = 47.1

width² + 0.35*width = 23.55

width = [tex]\frac{-0.35 \pm \sqrt{0.35^2 -4*1*(-23.55)}}{2*1} = -0.175 \pm 4,85599[/tex]

width = 4.68099 or width = -5.03099

Since the width can't be negative, it can only be 4.68099 feet.

length = 2*4.68099 + 0.7 = 10.06198 feet.

The width of the chocolate bar is 4.68 feet and the length is 10.06 feet.

To find the length and width of the chocolate bar, let's denote the width as w (in feet). According to the problem, the length, l, is 0.7 feet longer than twice the width, so we can express the length as:

l = 2w + 0.7

The area of the chocolate bar is given as 47.1 square feet. The area (A) of a rectangle is calculated by multiplying the length and the width:

A = l × w

Substituting the given values, we have:

47.1 = (2w + 0.7) × w

Expanding and rearranging the equation:

47.1 = 2w² + 0.7w

2w² + 0.7w - 47.1 = 0

This is a quadratic equation in the form ax² + bx + c = 0, where a = 2, b = 0.7, and c = -47.1. We can solve this using the quadratic formula: x = [tex]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Substituting the values into the quadratic formula:

w = [tex]\frac{-0.7 \pm \sqrt{0.7^2 - 4 \times 2 \times -47.1}}{2 \times 2}[/tex]

w = (-0.7 ± √(0.49 + 376.8)) / 4

w = (-0.7 ± √377.29) / 4

w = (-0.7 ± 19.42) / 4

Taking the positive root (since width cannot be negative):

w = (19.42 - 0.7) / 4

w = 18.72 / 4

w = 4.68

Now, substitute w back into the equation for length:

l = 2w + 0.7

l = 2(4.68) + 0.7 = 9.36 + 0.7 = 10.06

Thus, the width of the chocolate bar is 4.68 feet and the length is 10.06 feet.

Answer:

The third side is 8

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

a^2 + 15^2 = 17^2

a^2 +225 = 289

Subtract 225 from each side

a^2 = 64

Take the square root of each side

sqrt(a^2) = sqrt(64)

a= 8

Answer:

Sewage treatment and nitrous oxide

Step-by-step explanation:

Sewage to treatment and nitrous oxide is correctly paired with the greenhouse gases that it increases.

Greenhouse gas refers to gases that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect.

Examples of greenhouse gases and the most important greenhouse gases are methane, carbon dioxide (CO2), and water vapor.

Human activities such as fossil-fuel combustion are responsible for increase in the atmospheric concentration of various greenhouse gases, especially carbon dioxide, methane and ozone.

Answer:  The correct answer is sewage treatment and nitrous oxide

Step-by-step explanation:

The other options for rice cultivation, landfills, and deforestation are not paired with the proper greenhouse gases. However, sewage treatment plants are known for emitting nitrous oxide through their processing.

We're going from 1u : 3m to 1u : 9m so the new images will be three times smaller in each linear dimension.  So instead of a 3x9 box we get a 1x3 box.

y = 2x + 7 in the equation 8x - 4y = -28, isolate y on one side by subtracting 8x from both sides and then dividing by -4.

Solve for y: 8x - 4y = -28

Start by isolating y on one side of the equation.

Subtract 8x from both sides to get -4y = -8x - 28.

Finally, divide by -4 to find y = 2x + 7.

Answer:

The ordered pair is (1,8)

Step-by-step explanation:

Final answer:

The corresponding ordered pair for the function value f(1) = 8 is (1, 8), with 1 being the input and 8 being the output of the function.

Explanation:

If f(1) = 8, then the corresponding ordered pair is (1, 8). In function notation, the first value in the ordered pair is the input to the function (also known as the x-value or independent variable), and the second value is the output (also known as the y-value or dependent variable). Therefore, having f(1) = 8 tells us that when the input is 1, the output is 8, forming the ordered pair (1, 8).

Answer:

If you are looking for coordinates then its (0,5) (5,-20)

Step-by-step explanation:

Mr. Mole's burrow lies 5 meters below the ground. This is the same as saying that when Time is 0, Elevation is -5.

Therefore, the graph of the relationship should pass through the point (0,-5)

We are also given the rate of change of the relationship: 3 meters per minute. This means that when Time increases by 1, Elevation decreases by 3.

Therefore, the graph should also pass through the point                                (0+1,-5-3), which is the point (1,-8) However, this point doesn't appear on the grid! We need to find an equivalent pair of corresponding changes that would help us find a point that we can graph.

Note, for instance, that when Time increases by 5, Elevation decreases by 5x3= 15. Therefore, the graph should pass through the point

(0+5,-5-15)which is the point (5,-20)

Answer:

the coordinates are (0, -5) and (5, -20)

Step-by-step explanation:

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Check the coordinates in each graph.

(0, 4), (1, 4.5), (2, 5), (3, 27.5)

The graph that satisfies the coordinates given above is the answer.

The graph shown is not clearly visible.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = m = 1/2

y-intercept = 4

This means,

The equation of the line is y = (1/2)x + 4.

For x = 0, y = 4

For x = 1, y = 1/2 + 4 = 9/2 = 4.5

For x = 2, y = 1 + 4 = 5

For x = 3, y = 3/2 + 4 = 11/4

The coordinates from the line are:

(0, 4), (1, 4.5), (2, 5), (3, 27.5)

Now,

Check the coordinates in each graph.

The graph that satisfies the coordinates given above is the answer.

The graph shown is not clearly visible.

Thus,

Check the coordinates in each graph.

(0, 4), (1, 4.5), (2, 5), (3, 27.5)

The graph that satisfies the coordinates given above is the answer.

The graph shown is not clearly visible.

Final answer:

The simplest form of the expression √324 * a^2 * b^6 is 18ab^3, which corresponds to Option A.

Explanation:

First, let's simplify the expression √324 * a^2 * b^6. The square root of 324 is 18, since 18 x 18 = 324. Now, we simplify 18 * a^2 * b^6 which gives us 18ab^3 when taking the square root of each term (a squared is a times a, and the b to the power of 6 simplifies to b to the power of 3 because √(b^6) = b^3).

The expression is already in its simplest form as an integer power. Therefore, the correct answer is Option A. 18ab^3.

Answer: The answer is 18.

Step-by-step explanation:

Since the average of all 10 players was 75, the total number of baskets made was 10 × 75 = 750. Also, since 8 of the player had an average of 79, they made a total of 8 × 79 = 632 points. The other 2 players, therefore, made 750- 632 = 118 baskets. The most baskets that the player with the highest number could have made was 100, so the player with the lowest number had to have made at least 18.

The smallest number of baskets anyone could have made is 18, computed by first finding the total of all scores, then the total of the 8 middle scores and subtracting, and finally subtracting a maximum possible individual score from the remaining total.

One way to approach this problem is to calculate the total baskets scored initially, then the total scored after removing the highest and lowest scorers. We know that there are 10 people in total, each making an average of 75 baskets. So, the total initial scores is 10 * 75 = 750 baskets.

When the highest and lowest scorers are removed, the remaining 8 players have an average of 79 baskets each, which gives a total of 8 * 79 = 632 baskets. Subtracting the latter total from the initial total, we get 750 - 632 = 118 baskets, which are the combined scores of the highest and lowest players.

To find the smallest number of baskets anyone could have made, we consider a case where the highest score is as high as possible while still being within realistic boundaries. Since each player shot 100 free throws, the maximum score by one player could be 100. Therefore, the smallest number of baskets made by a player, could be 118 - 100 = 18 baskets.

Answer:

1. 2/3

2. doesn't exist

3. 2

4. x ≥ 0

5. y ≥ 2

Step-by-step explanation:

If we were to take any two points on the line and divide the difference of the y-coordinates by the difference of the x-coordinates, we'd get the slope. So, take any two points: (0, 2) and (3, 4). The slope is:

(4 - 2) / (3 - 0) = 2/3

The x-intercept is where the line crosses the x-axis, but since the line only starts at (0, 2), the x-intercept doesn't exist.

The y-intercept is where the line crosses the y-axis, which is at point (0, 2) so the y-intercept is 2.

The domain is the possible x-values. Here, because the smallest x-value is 0 (from the point (0,2)), and there is no largest x-value (the arrow at the end of the line indicates the graph goes on to infinity), the domain is: x ≥ 0.

The range is the possible y-values. Here, the smallest possible y value is 2 (from (0, 2)) and the largest is infinity, so the range is: y ≥ 2.

If you do this step by step, you will see it is actually easy! So first, the slope is found by rise over run!

rise = 2; run = 3

Slope = 2/3

The graph doesn't extend to the x axis!

X intercept = Not there

The y intercept is where the function touches the y axis, this is already evident on the graph!

Y intercept = (0,2)

The domain is all possible x values, the function starts at (0,2) and can't go past that point which makes our domain...

Domain =  [tex]0\leq x[/tex]

The range is all possible y values, and since the function's vertical limit is 2, then our range is...

Range =  [tex]2 \leq y[/tex]
