The amount of cubic feet that the storage shed can hold is 168 ft³

An equation is an expression that shows how numbers and variables are linked together using mathematical operations such as addition, subtraction, multiplication and division.

The volume of the storage shed is the product of the base area and the height. It is given by:

Volume = base area * height

From the diagram, the base is a triangle. Hence:

Area of base = (1/2) * base * height = (1/2) * 8 ft * 7 ft = 28 ft²

Volume = base area * height = 28 ft² * 6 ft. = 168 ft³

The volume of the storage shed is 168 ft³

An appropriate scale for the y-axis would be to have each unit represent 5 minutes of time.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Since the data represents the average time employees spent online, the y-axis of the bar graph should represent time in minutes.

To choose an appropriate scale for the y-axis.

we need to consider the range of values in the data set.

The lowest value is 15 minutes

and the highest value is 60 minutes

Range of values is 60 - 15 = 45 minutes.

It's best to choose a scale that divides the range of values into equal intervals.

One possible option is to use a scale where each unit represents 5 minutes of time. This would allow us to represent the data accurately without making the bars too small or too large.

Therefore, an appropriate scale for the y-axis would be to have each unit represent 5 minutes of time.

Hey there! Johnny Sins always here to help,

To find out what score Natasha needs to earn on her next test, we can use the following formula:

Average = (sum of all scores) / number of scores

Let's call the score Natasha needs to earn on her next test "x".

Her average so far is:

Average = (94 + 89 + 88 + 92 + 85) / 5 = 90

Her average after her next test will be:

Average = (94 + 89 + 88 + 92 + 85 + x) / 6

Now, we need to set this equal to 90% and solve for x:

90 = (94 + 89 + 88 + 92 + 85 + x) / 6

90 * 6 = (94 + 89 + 88 + 92 + 85 + x)

540 = (94 + 89 + 88 + 92 + 85 + x)

x = 540 - (94 + 89 + 88 + 92 + 85)

x = 540 - 448

x = 92

So, Natasha needs to earn a 92% on her next test to average at least 90%.

4 3/4 pounds amount of sugar were left after Garth used 9 1/2 pounds for the lemonade.

9 1/2 pounds of sugar were used from 14 1/4 minus 4 3/4.

Garth needed 14 1/4 pounds of sugar to make lemonade for the school carnival, so he purchased them. He had 4 3/4 pounds of sugar left over when he had done preparing the lemonade. This indicates that he made the lemonade using 9 1/2 pounds of sugar. He took the 14 1/4 pounds of sugar he purchased and subtracted the 4 3/4 pounds that were leftover to get at the amount of sugar he utilised, or 9 1/2 pounds. This indicates that the correct response is D: The lemonade required 9 1/2 pounds of sugar.

The number of adults in the museum, using the fractional value of girls and boys, is 75.

A fractional value refers to a portion of the total value.

A fractional value can be depicted in fractions, decimals, or percentages.

A fractional value can also be represented as a ratio or proportion.

In this situation, the fractional number of adults is determined using subtraction.

The total number of people in a museum = 250

The fraction of girls in the museum = 2/5

2/5 of 250 = 100 girls

The fraction of boys in the museum = 3/10

3/10 of 250 = 75

Alternatively:

2/5 + 3/10 = 7/10

7/10 of 250 = 175

Therefore, the number of adults = 75 [250 - (100 + 75)]

The measure of angle ACD for the given circle is 67.5 degree.

A triangle is inside a circle when a circle encircles it, and each vertex of the triangle touches the circle.

When a circle encircles a triangle, the triangle lies outside the circle and the circle makes one point contact with each of the triangle's sides. The triangle's sides are perpendicular to the circle.

Given that,

The inscribed angle CDA = 1/2(arc AC).

arc AC = 90 degree.

Then:

∠ CDA = 90 / 2

∠ CDA = 45

Triangle ACD is isosceles, so:

∠ ACD + ∠ CAD + ∠ CDA = 180 degree

Here, ∠ ACD = ∠ CAD

∠ ACD + ∠ACD + ∠ CDA = 180 degree

∠ ACD = 180-45 / 2

∠ ACD   = 67.5 degree

Hence, the measure of angle ACD for the given circle is 67.5 degree.

Using the two tangent exterior angle theorem:

x = 6

m(NK) = 153°

According to the two tangent exterior angle theorem, when you draw two tangent lines from a point outside a circle, the angle formed between them is equal to half the difference between the measures of the arcs they intercept inside the circle.

Therefore, using the above theorem, we have:

7x + 6 = 1/2[(25x + 3) - (9x + 3)]

Solve for x:

2(7x + 6) = 25x + 3 - 9x - 3

14x + 12 = 16x

14x - 16x = -12

-2x = -12

x = -12/-2

x = 6

m(NK) = 25x + 3 = 25(6) + 3

m(NK) = 153°

Answer: The coordinates of the image of a figure after a rotation of 0.25 degrees about the x-axis can be found using the following formulas:

x' = x

y' = y * cos(θ) - z * sin(θ)

z' = y * sin(θ) + z * cos(θ)

where (x, y, z) are the original coordinates and (x', y', z') are the new coordinates. In this case, we only need to find the y' coordinate because the rotation is about the x-axis and the x coordinate will not change.

For each point, we can use the formula to find the y' coordinate:

A (2, 6) -> y' = 6 * cos(0.25) - 0 * sin(0.25) = 5.99911... ~ 6

B (0, 0) -> y' = 0 * cos(0.25) - 0 * sin(0.25) = 0

C (-5, 8) -> y' = 8 * cos(0.25) - 0 * sin(0.25) = 7.99823... ~ 8

D (-2, 10) -> y' = 10 * cos(0.25) - 0 * sin(0.25) = 9.99649... ~ 10

So, the new coordinates after rotating 0.25 degrees about the x-axis are:

A (2, 6) -> (2, 6)

B (0, 0) -> (0, 0)

C (-5, 8) -> (-5, 8)

D (-2, 10) -> (-2, 10)

The coordinates of the points have not changed after the rotation because the rotation angle is very small.

Step-by-step explanation:

As the angle increases from 0 to π/2, the value of sine increases, and the value of cosine decreases.

Trigonometry is a branch of mathematics that deals with the relationships between angles and sides of triangles.

Let us first understand the concept of sine and cosine. In a right-angled triangle, the sine of an angle is defined as the ratio of the length of the side opposite to the angle and the length of the hypotenuse. Similarly, the cosine of an angle is defined as the ratio of the length of the adjacent side and the length of the hypotenuse.

As the angle θ increases from 0 to π/2, the length of the opposite side (the numerator in sine) of the triangle increases, and the length of the hypotenuse (the denominator in sine) remains the same. Therefore, the value of sine increases as θ increases.

On the other hand, as the angle θ increases from 0 to π/2, the length of the adjacent side (the numerator in cosine) decreases and the length of the hypotenuse (the denominator in cosine) remains the same. Therefore, the value of cosine decreases as θ increases.

This behavior is consistent with the fact that sine is an increasing function, while cosine is a decreasing function within this range of angles.

Step-by-step explanation:

2x^2 -x^2 will be x^2

3x+x is 4x

-4+9 is 5

Answer:

Step-by-step explanation:

The slope of a line between two points (x1, y1) and (x2, y2) is given by:

m = (y2 - y1) / (x2 - x1)

In this case, we are given that m = -1/2, so substituting in the two points we have:

-1/2 = (9 - 12) / (x - 8)

Expanding and simplifying the equation:

-1/2 = -3 / (x - 8)

Multiplying both sides by -2:

1 = 3 / (x - 8)

Multiplying both sides by (x - 8):

x - 8 = 3

Adding 8 to both sides:

x = 11

So the x-coordinate of the second point is x = 11.
