Hello!

\(\large\boxed{\frac{19}{30}}\)

There are 60 minutes in an hour, so:

38 / 60

Reduce the fraction by diving by the GCF, or 2:

(38/2) / (60/2) = 19 / 30.

Answer:Isolate the g

w = 7 - √g

Do the opposite of PEMDAS, first subtract 7 from both sides

w (-7) = -√g + 7 (-7)

w - 7 = -√g

multiply -1 (as -√g is the same as -1√g) to both sides

-1(w - 7) = √g

-1w + 7 = √g

to get rid of the square root, you must square both sides

Note: -1w is the same as -w

Note: you are squaring all the terms on the other side, not just one.

(-w + 7)² = (√g)²

g = (-w + 7)²

g = (-w + 7)(-w + 7) (note, this can be the answer your teacher wants, or                                            g = (-w + 7)²    )

Use the FOIL method (First, Outside, Inside, Last)

(-w)(-w) = w²

(-w)(7) = -7w

(7)(-w) = -7w

(7)(7) = 49

g = w² - 7w - 7w + 49

simplify (combine all like terms)

g =w² - 7w - 7w + 49

g = w² - 14w + 49

g = w² - 14w + 49 is your answer

Step-by-step explanation:

The number of yards, as a mixed number, will you drive until you reach this exit is 333 1/3 yards

The complete question is added as an attachment

From the attached figure, we have:

Exit = 1000 feet

From the question, we have

3 feet = 1 yard

So, the number of yards is

Number of yard =Exit/3 yards

This gives

Number of yard = 1000/3 yards

Evaluate the quotient

Number of yard = 333 1/3 yards

Hence, the number of yards, as a mixed number, will you drive until you reach this exit is 333 1/3 yards

The inequality can be used to determine the number is C . 0.40x > x/2 - 15

Given :

Forty percent of a number is greater than one-half the number decreased by 15.

And we need to find the number that is used to determine the inequality.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Let us consider x be that unknown number.

We have divide it into two parts.

First, forty percent of the number and it can be written as 40%x or 0.40x.

The greatest number of sides that can result from a cross section of a rectangular prism is 6.

To see why, consider a rectangular prism. The prism has 6 faces, which are all rectangles. If we take a cross section of the prism, the section will intersect some of the faces, resulting in a closed shape. The shape will have at most as many sides as the number of sides of the faces that the section intersects.

Since each face of the rectangular prism has 4 sides, the maximum number of sides that can result from a cross section is 4 x 6 = 24. However, this is only possible if the section intersects every face of the prism, which is unlikely to occur in general. In practice, a cross section of a rectangular prism is more likely to intersect just a few of the faces, resulting in a shape with fewer sides. Therefore, the greatest number of sides that can result from a cross section of a rectangular prism is 6, which occurs when the section intersects all 6 faces.

The volume of the two objects pyramid and cylinder are not same hence, Jude's calculations are not correct.

There are two ways to approximate a number to a specific number of digits or decimal places: rounding and truncating. When a number is rounded, the value is adjusted to the value that is closest while still maintaining the desired level of accuracy. To round the number 3.14159 to two decimal places, for instance, we would start with the third decimal place, which is 1, and round up or down depending on whether the next digit is 5 or less. 3.14 is the result of rounding 3.14159 to two decimal points.

On the other hand, truncating only entails removing the digits that exceed the specified level of accuracy.

The volume of the square pyramid is given as:

Volume of pyramid = (1/3) x Base area x Height

For base edge = 12 and height = 10:

for the base are we have:

Base area = 12 (12) = 144 sq, in.

Now, substituting the values we have:

Volume of pyramid = (1/3) x 144 sq. in. x 10 in. = 480 cu. in.

The volume of cylinder is given as:

Volume of cylinder = π x r² x h

Now,

Volume of cylinder = 3.14 x 6.77² sq. in. x 10 in. = 1443 cu. in.

The rate of change of the radius at the instant, when the sphere's radius is 8 centimeters, is approximately 5.286 cm/min.

We have,

We know that the formula for the volume of a sphere is given by:

V = (4/3)πr³

Differentiating both sides with respect to time.

dV/dt = 4πr² (dr/dt)

where dV/dt is the rate of change of volume, and dr/dt is the rate of change of radius.

Substituting the given values, we get.

6645 = 4π(8)² (dr/dt)

Solving for dr/dt.

dr/dt = 6645 / (4π(8)²) ≈ 5.286 cm/min

a. An approximate equation of the line of best fit for the data is y = x + 4.

b. By using this equation, the amount of money spent on entertainment for a student who works 10 hours is $12.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (12 - 8)/(8 - 4)

Slope (m) = 4/4

Slope (m) = 1.

At data point (4, 8) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 8 = 1(x - 4)

y = x - 4 + 8

y = x + 4

When x = 8 hours, the amount of money spent can be calculated as follows;

y = x + 4

y = 8 + 4

The most appropriate units to describe the cost of the sandbox would indeed be dollars.

When describing the cost of an item or service, it is essential to use the unit that represents the currency being used for the transaction. In this case, the total cost of the sand for the school's sandbox is given in dollars. To maintain consistency and clarity, it is best to express the cost in the same unit it was provided.

Using dollars as the unit for the cost allows for clear communication and understanding among individuals involved in the transaction or discussion. Dollars are widely recognized as the standard unit of currency in many countries, including the United States, where the dollar sign ($) is commonly used to denote monetary values.

Using meters, the unit for measuring the dimensions of the sandbox, to describe the cost would be inappropriate and could lead to confusion or misunderstandings. Mixing units can cause ambiguity and hinder effective communication.

Therefore, it is most appropriate to describe the cost of the sand in dollars, aligning with the unit of currency provided and commonly used in financial transactions. This ensures clarity and facilitates accurate comprehension of the cost associated with the sand purchase for the school's sandbox.

Answer:

The answer is 0.01

Step-by-step explanation:

The area of the larger figure that is similar to the smaller one is: 28.2 m².

Where A and B represent the areas of two similar figures, and a and b are their corresponding side lengths, respectively, the formula that relates their areas and side lengths is:

Area of figure A / Area of figure B = a²/b².

Given that the two figures are similar as shown in the image above, find each of their respective side lengths if we are given the following:

Perimeter of smaller figure = 20 m

Area of smaller figure = 19.6 m²

Perimeter of larger figure = 34m

Area of larger figure = x

Therefore:

20/34 = a/b

Simplify:

10/17 = a/b.

Find the area (x) of the larger figure using the formula given above:

10²/12² = 19.6/x

100/144 = 19.6/x

100x = 2,822.4
