What is 3(-6)2 at the top ?

Answer:

7.8125

Step-by-step explanation:

6.25 x 1.25

The marked-up price is $7.81 if the amount is $6.25 and the rate in percentage is 25%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

The amount = $6.25

The rate in percentage = 25%

The marked-up price = 6.25 + 25% of 6.25

The marked-up price = 6.25 + (25/100)6.25

The marked-up price = 6.25 + (0.25)6.25

The marked-up price = 6.25 + 1.56

The marked-up price = $7.81

Thus, the marked-up price is $7.81 if the amount is $6.25 and the rate in percentage is 25%.

The radius of circle is shown by the red segment.

The radius of a circle is the distance between the circle's centre and any point on its circumference. It is commonly represented by the letters 'R' or 'r'. This number is significant in practically all circle-related formulae. A circle's area and circumference are also measured in terms of radius.

The radius is the distance from the circle's centre to its perimeter. The diameter is always twice as large as the radius.

The point in the center is called as Center of Circle.

Now, the axis of symmetry pass through the center.

Here the red segment which starts from center and touches the boundary of circle is called as the radius of circle.

Thus, the red segment is radius.

Answer:

x = 11, x = -11

Step-by-step explanation:

I know this is kind of late but the two previous answers were wrong.

We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:

√x² = √121

x = √121

You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

Answer:

x=11

Step-by-step explanation:

You would add up the three jumping distances.

4.34ft+4.56+4.23=13.13

Then you would divide them by the total number of numbers there are.

13.13/3= your answer, which is 4.376

4.376 is the mean of the heights when Kevin jumped three high jumps 4.34 feet, 4.56 feet, and 4.23 feet.

Kevin jumped three high jumps of 4.34 feet, 4.56 feet, and 4.23 feet. We need to find the mean of the heights.

The mean is the average or the most common value in a collection of numbers

The formula for mean= Sum of data values/ Total number of data values.

The given three high jumps of kevin are 4.34 feet, 4.56 feet, and 4.23 feet.

We need to find the mean of his three heights.

From the formula of mean,

The three data values are 4.34 feet, 4.56 feet, and 4.23 feet.

Mean=Sum of data values/ Total number of data values.

=(4.34+4.56+4.23)/3

Answer:

Its the same area as the original shape.

Step-by-step

If you descompose a original area into smaller pieces. The mathematical process of cutting areas won’t add or substract area. Even of you cut the original area to infinitesimal size pieces, the infinite number of pieces will sum up the same area as original area.

When a rectangle is decomposed along the diagonal and repositioned, the resulting shape is a parallelogram with the same area as the original rectangle.

To decompose the rectangle along the diagonal, we can cut it in half from one corner to the opposite corner. This creates two right triangles. We can then reposition the triangles to create a parallelogram. The area of the parallelogram is the same as the area of the original rectangle.

This can be shown using the formula for the area of a triangle, which is 1/2 times the base multiplied by the height. Since the base and height of each triangle are equal to the length and width of the rectangle, the area of each triangle is (1/2) * length * width.

When we rearrange the triangles to form a parallelogram, the base is equal to the length of the rectangle and the height is equal to the width of the rectangle. Thus, the area of the parallelogram is length * width, which is the same as the area of the original rectangle.

The statement [tex]1\frac{2}{5}[/tex] - 3/4 = 1/4 + 2/5 is true.

Let's start by converting the mixed numbers into improper fractions:

[tex]1\frac{2}{5}[/tex] = (5 × 1 + 2) / 5 = 7/5

3/4 remains the same.

1/4 + 2/5 = 5/20 + 8/20 = 13/20

To proceed with the calculations, we need to find a common denominator for 5 and 4, which is 20.

Multiplying the numerator and denominator of 7/5 by 4, we get:

(7 × 4) / (5 × 4) = 28/20

Multiplying the numerator and denominator of 3/4 by 5, we get:

(3×5) / (4×5) = 15/20

Therefore, the equation becomes:

28/20 - 15/20 = 13/20

Simplifying the left side:

(28 - 15) / 20 = 13/20

So, 7/5 - 3/4 does indeed equal 1/4 + 2/5, both of which simplify to 13/20.

Hence, the statement [tex]1\frac{2}{5}[/tex] - 3/4 = 1/4 + 2/5 is true.

Final answer:

After converting all fractions to have a common denominator of 20, it was determined that 1 2/5 - 3/4 is indeed equal to 1/4 + 2/5, as both expressions simplify to 13/20.

Explanation:

To verify if 1 2/5 - 3/4 is equal to 1/4 + 2/5, we will calculate both expressions step by step:

Firstly, to subtract fractions, they must have a common denominator:

1 2/5 can be written as 7/5 since 1 + 2/5 is the same as 5/5 + 2/5.

Now, to make 3/4 have the same denominator as 7/5, multiply both numerator and denominator by 5:

3/4 * 5/5 = 15/20

Next, convert 7/5 to twentieths by multiplying by 4/4:

7/5 * 4/4 = 28/20

We can now subtract the two fractions:

28/20 - 15/20 = 13/20

Now let's calculate 1/4 + 2/5.

To add these two fractions, find a common denominator.

Our common denominator will be 20, as before. Multiply the numerators and denominators as needed:

1/4 * 5/5 = 5/20

2/5 * 4/4 = 8/20

The sum of these two fractions is:

5/20 + 8/20 = 13/20

Through these steps, we have shown that 1 2/5 - 3/4 is indeed equal to 1/4 + 2/5, as they both simplify to 13/20.

The solution for y is y = 2x + 1

Step-by-step explanation:

* Lets explain how to solve an equation for one of the variables

- We need to solve the equation 16x + 9 = 9y - 2 x for y

- That means we want to find y in terms of x and the numerical term

- the equation has two sides, one side contains x and numerical term

 and the other side contains y and x

- We need to separate y in one side, and other term in the other side

* Lets do that

∵ 16x + 9 = 9y - 2x

- Add 2x to both sides to cancel -2x from the right side

∴ 16x + 2x + 9 = 9y - 2x + 2x

- Add like terms in each side

∴ 18x + 9 = 9y

- Divide each term by the coefficient of y ⇒ (÷9)

∴ (18 ÷ 9)x + (9 ÷ 9) = (9 ÷ 9)y

∴ 2x + 1 = y

- Switch the two sides

∴ y = 2x + 1

* The solution for y is y = 2x + 1

Answer:The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 12,500 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 12,500

New Number: 1.2500

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 2 5 0 0

Decimal Count: 1 2 3 4

There are 4 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.25 (Please notice any zeroes on the end have been removed)

b = 4

Now the whole thing:

1.25 x 104

Step 4

Check your work:

104 = 10,000 x 1.25 = 12,500

Step-by-step explanation:

10(1 + 3b) = -20

Isolate b.

Apply the distributive property: a(b + c) = ab + ac.

10(1 + 3b) = -20

10 + 30b = -20

Subtract 10 from both sides.

10 + 30b - 10 = -20 - 10

30b = -30

Divide both sides by the coefficient, 30.

b = -1
