To find the estimated sum, round each addend to the nearest ten thousand by looking at the digit in the ten thousand places. Then add the rounded numbers together.

To round each addend to the nearest ten thousand, look at the digit in the ten thousand places. If the digit is 5 or greater, round up by increasing the number in the ten thousand place by 1. If the digit is less than 5, round down by keeping the number in the ten thousand places the same. For 337,961, the digit in the ten thousand places is 9, so it rounds up to 340,000. For 482,746, the digit in the ten thousand places is 7, so it rounds down to 480,000. Now, you can find the estimated sum by adding the rounded numbers, which would be 340,000 + 480,000 = 820,000.

The total area of the trapezoid is 73.5 square feet, calculated by adding the area of the square (49 square feet) to the area of the isosceles right triangle (24.5 square feet).

The area of a trapezoid consists of the area of a square and the area of an isosceles right triangle. Since the square has side lengths of 7 feet, its area is 49 square feet (7 feet x 7 feet). The isosceles right triangle, with both the base and the height being 7 feet, has an area of 24.5 square feet (1/2 x 7 feet x 7 feet). Therefore, the total area of the trapezoid is the sum of the areas of the square and the triangle.

Total area = Area of square + Area of triangle

Total area = 49 square feet + 24.5 square feet = 73.5 square feet.

The work done to stretch a spring is calculated using Hooke's Law, denoted by the formula W = 1/2kx², where 'k' is the spring constant and 'x' the displacement. The displacement is the difference between the final and initial lengths of the spring (7.0 cm - 3.0 cm). However, without the spring constant, a specific numerical answer cannot be provided.

The problem requires calculating the work done to stretch a spring. This can be done using Hooke's Law in Physics, which states that the force necessary to extend or compress a spring by a distance 'x' from its equilibrium position is proportional to 'x'. The magnitude of the force applied is represented as F = kx, where 'k' is the spring constant. However, the work done, W, against this force is given by 1/2kx².

To calculate, we need to know the value of the spring constant 'k', and the displacement 'x', which is the difference between the final length (7.0 cm) and the initial length (3.0 cm) of the spring. Without the spring constant, we, unfortunately, cannot provide a numerical answer.

The picture is 7w - 2 units longer than it is wide, this is found by subtracting the width (4+w) from the length (8w+2).

To find out how much longer the picture is than it is wide, we must compare the picture's length and width. Given the picture's width is 4+w and the length is 8w+2, we subtract the width from the length to find the difference:

Length - Width = (8w+2) - (4+w) = 8w + 2 - 4 - w = 7w - 2.

Therefore, the picture is 7w - 2 units longer than it is wide.

Final answer:

Janelle should plan to spend 3 hours walking back.

Explanation:

To find out how long Janelle should plan to spend walking back, we need to calculate the total time it takes her to run and walk. Since she runs at a speed of 7mph, she completes the distance of the race in 1 hour (4 miles / 7mph = 0.57 hours = 1 hour). Therefore, she spends 1 hour running and 3 hours left for walking. To find out the distance she walks back, we use the formula distance = speed x time. Since she walks at a speed of 3mph, the distance she walks back is 3mph x 3 hours = 9 miles.

Answer:

(3a,a)

Step-by-step explanation:

As you know the component on the X vertex is the first that is represented when setting point coordenates, and the second value is in the Y vertex, as you can see the value for Y is a, and in the problem says that the longer side is three times the short side, since the Y vertex is the short side, that means the X vertex will have the longer side, making it 3a. So the coordenates will be (3a,a).

Answer:

Option C. is the correct option.

Step-by-step explanation:

The given line in the graph passes through two points (0, 3) and (3, 7).

We have to find the equation of the line.

Since y = mx + c is the standard equation of a line

where m = slope of the line

c = y - intercept

Slope of a line m = [tex]\frac{(y-y')}{(x-x')}[/tex]

Now we put the values of x and y to find the slope of this line.

m = [tex]\frac{7-3}{3-0}=\frac{4}{3}[/tex]

Since (0, 3) passes through the line

3 = 0 + c

c = 3

Equation of the line will be

[tex]y=\frac{4}{3}x+3[/tex]

Option C. is the answer.

Answer:

Step-by-step explanation:

To solve the equation 3x + 1 + 2x = 2 + 4x, you would first combine like terms, then eliminate variable terms on one side of the equation, and finally solve for x.

In solving the equation 3x + 1 + 2x = 2 + 4x, the first step would be to combine like terms on both sides of the equation. This means adding or subtracting the same type of terms together. In this case, you would combine the x terms on the left side and the constant terms on the right side. The equation will then be simplified to 5x + 1 = 2 + 4x.

The next step would be to get rid of the variable terms on one side of the equation. To do this, you can subtract 4x from both sides of the equation. This will result in x + 1 = 2.

Finally, you can solve for x by subtracting 1 from both sides of the equation. This gives us the solution x = 1.

Final answer:

The actual product is less than the estimate. The numbers differ by less than one.

Explanation:

Javier rounded to the nearest half to estimate the product of 3 2/5 and -3 7/8.

To estimate the product, we can round both numbers to the nearest half, which gives us 3.5 and -3.5. Multiplying these rounded numbers gives an estimate of -12.25.

The actual product of 3 2/5 and -3 7/8 is -3.4. Therefore, the actual product is less than the estimate. The numbers differ by less than one.

Final answer:

The greatest common factor of 15 and 27 is 3, which is the largest number that divides both numbers without a remainder.

Explanation:

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder. To find the GCF of 15 and 27, list the factors of each number:

Factors of 15: 1, 3, 5, 15

Factors of 27: 1, 3, 9, 27

The common factors of 15 and 27 are 1 and 3. The largest of these is 3, therefore the greatest common factor of 15 and 27 is 3.

Answer:

The sales tax to be paid for the pair of shoes is $2.29.

Step-by-step explanation:

If the price of a pair of shoes is $45.90, and the sales tax rate for it is of 5%, in order to know the sales tax to be paid we have to do the following calculation:

(45.90 x 5) / 100 = X

229.5 / 100 = X

2.295 = X

So, as we can see, the sales tax to be paid is $2.29

If we solve the equation which is (F × x ) - (g × x ) = h , we will get the value of x as x = h / ( F - g ).

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

An equation is given which is :

(F × x ) - (g × x ) = h

We have to solve this equation to get the value of the variable x.

So, the value of x can be calculated as :

(F × x ) - (g × x ) = h

Taking common x from LHS :

x ( F - g ) = h

Dividing by ( F - g ) on both sides we get :

[ x ( F - g ) / ( F - g )] = h / ( F - g )

or

x = h / ( F - g )

Therefore , if we solve the equation which is (F × x ) - (g × x ) = h , we will get the value of x as x = h / ( F - g ).
