Answer:345600000000

Step-by-step explanation:

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

Example: Convert 357,096 to Scientific Notation

Move the decimal 5 places to the left to get 3.57096

a = 3.57096

We moved the decimal to the left so b is positive

b = 5

The number 357,096 converted to scientific notation is 3.57096 x 10^5

The truck takes a time of 1 longer to complete the delivery than that of the vehicle.

We are given the function that represents the distance (in miles) of the car from the starting point after x hours as;

C(x) = -72|x - 5| + 360

Now, at a time of x = 5 hours, the distance covered by the car is;

C(5) = -72|5 - 5| + 360

C(5) = 0 + 360

C(5) = 360  miles

Thus, the car covers a distance of 360 miles in 5 hours

Now, from the given graph that represents the truck’s distance from the starting point, we see that after 6 hours, it has covered 360 miles. Thus, we say that the truck covers 360 miles in 6 hours.

Thus, the truck takes 1 longer to complete the delivery than that of the vehicle.

The length of the side of the square cut from the box is 7 cm.

For the given question;

The dimension  of the box is;

Length = 60 cm.

Breadth = 40 cm.

Then the area of the base of the rectangular box before cutting is;

Area =  length×breadth

Area = 60 × 40

Area = 2400 cm².

Let the side of the square cut be 'x'

Then the area of one square is x².

As, square is being cut from each corner, thus the total area will be; 4x².

The area of resulting base after square is cut is 2204 cm².

Thus, the area of cut square = old area - resulting area

Area cut = 2400 - 2204

Area cut = 196

Thus, Area cut = total area of 4 square.

Area cut = 4x²

4x² = 196

On solving;

x = 7.

Thus, the length of each square cut from the rectangle is 7 cm.

Answer: Improper Response

Step-by-step explanation: Please be more specific and I'll answer

The equation of line in the slope intercept form is;  y = 3x - 45.

The equation of the line in slope intercept form is;

(y - y₁) = m(x - x₁)

The given coordinates are-

(x₁ ,y₁) = (-9, 12)

the slope of the line is;

slope = m = 3.

Put the values in the equation;

y - (-9) = 3(x - 12)

y + 9 = 3x - 36

y = 3x - 36 - 9

y = 3x - 45

Therefore, the equation of line in the slope intercept form is;

y = 3x - 45.

Step-by-step explanation:

The ratio of isaiah,s liabilities is less than 1.

Let , isaiah has total debt (not including mortgage) is $7,410.

Her net worth (not including his home) is $21,000.

Therefore, his debt-to-equity ratio is $7,410 divided by $21,000, or 0.35.

therefore, this ratio is less than 1, isaiah has not reached the upper limit of debt obligations.

Your net worth can be calculated by subtracting all of your debts and liabilities from your assets. You may have items that are intangible or difficult to sell that may be excluded from calculations used by financial institutions to determine loan eligibility.

the difference between your assets and your liabilities is your net worth. The formula looks like this: (Sum of the current value of all assets) - (Sum of the current total of all outstanding liabilities) = Net worth.

The net worth of a business is also known as its book value, or as its owners' (stockholders') equity. This figure can be computed relatively easily using information found on a company's balance sheet. However, even if the balance sheet isn't available, you can still calculate a business' net worth if you have some basic financial information.

Answer:

The volume of the cube given the length of each edge is 8/27 units³.

A cube is a three-sided object that has six faces, eight vertices and twelve edges. The six faces of a cube have the shape of a square. Thus, the length, width and height of a cube have the same dimensions. The angle between any two face in a cube measures 90 degrees. A cube is also known as a regular hexahedron.

A cube is one of the five platonic solids. A platonic solid is a solids that are made up of equivalent faces that are made up of congruent convex regular polygons.

Given the length of each edge of a cube, the volume can be determined by multiplying the given length edge by itself three times. Or by find the cube of the given length edge.

Volume of the cube = length edge³

The numerical length of HJ is 33

The given parameters;

distance of HI = x

distance of HJ = 3x - 9

distance of IJ = x + 5

To find:

the numerical length of HJ

A sketch of the positions of the line segments is shown below;

|<-----x------->|<--------------------------x+5------------------------------>|

H---------------I----------------------------------------------------------------J

The value of x will be calculated by setting up the following equation;

HI + IJ = HJ

x + x + 5 = 3x - 9

2x + 5 = 3x - 9

collect similar terms together;

2x - 3x = -9-5

-x = -14

x = 14

The numerical length of HJ is calculated as;

HJ  = 3(14) - 9

HJ = 42 - 9

HJ = 33

Thus, the numerical length of HJ is 33

Answer:

Step-by-step explanation:

So start with your parentheses, (8-5)(5-3). 8-5=3 and 5-3=2, and when two parentheses are next to each other they will be multiplied.

Example: 3(5-3)^2 ---> 3 x 2^2
Although this "^" means "to the power" so 2 to the power of 2 is 2 x 2=4

So putting it all together we get, (8-5)(5-3)^2 --> 3(5-3)^2 --> 3 x 2^2 [2x2=4] --> 3 x 4 = 12
Your final answer is 12!
