The result of John's multiplication in standard form is

3.12 × 10⁹

To express the result in standard form, we need to represent it as a number between 1 and 10 (inclusive) multiplied by a power of 10.

In other words, the number should have the form:

a × 10ⁿ

where "a" is a decimal number greater than or equal to 1 and less than 10, and "n" is an integer representing the power of 10.

Let's calculate the result of John's multiplication:

= 400,000 × 7,800

= 3,120,000,000

Now, we need to convert this number into standard form. To do that, we will move the decimal point to the left until there is only one non-zero digit to the left of the decimal point.

The number of places we move the decimal point will give us the power of 10.

In this case, we will move the decimal point three places to the left:

3.120000000 × 10⁹

Now, we can simplify the number by removing trailing zeros:

3.12 × 10⁹

So, the result of John's multiplication in standard form is

3.12 × 10⁹

The volume of the sphere is 267. 95 cm³.

The radius of the sphere is 4cm.

The volume of a sphere is the three-dimensional space occupied by a sphere.

The volume of the sphere is determined by the following formula;

[tex]\rm Volume = \dfrac{4}{3} \pi r^3[/tex]

Where r is the radius of the sphere.

Substitute all the values in the formula;

[tex]\rm Volume = \dfrac{4}{3} \pi r^3\\\\\rm Volume = \dfrac{4}{3} \times (3.14) \times 4^3\\\\Volume = 4 \times 1.04 \times 64\\\\Volume = 267.95\ cm ^3[/tex]

Explanation:

Let's review three examples of product of exponent rule and dividing of exponent rule before solving the problem.

Looking at these examples, we can tell that we can multiply exponents and subtract exponents. These rules are applied in this question. Now, let's solve the question to obtain our answer.

Solution:

Final Answer:

Answer:

7295

Step-by-step explanation:

The first thing we can do is rule out any numbers that cannot be divided by 5. Any number that ends in a 0 or a 5 can, so 627 cannot be. The next thing we do is use the division rule for dividing by 3. The rule states that if you add up the digits of a number, and it is divisible by 3, then so is that number.

2+8+5= 15 (multiple of 3)

5+4+9+0=18 (multiple of 3)

7+2+9+5=23 (not a multiple of 3)

4+3+6+9+5=27 (multiple of 3)

Answer:

j=35

Step-by-step explanation:

Since the shorter side has a length of 60 the other shorter side also has a length of 60 and the whole rectangle's perimeter is 400 if you add the shorter sides you get 120 to find the total length of the longer sides we have to subtract 400 by 120 and by doing that we get 280 so the total length of the longer sides is 280 and since there are 2 sides we have to divide 280 by 2 and we get 140 but, j *4 is 140 and we still have to find j so we divide 140 by 4 to get 35 and thus j=35

The value of  x from the expression is 2

Given the expression

2x = 74/2 - 37

We are to calculate the value of  x from the expression

2x = 37 - 37

Since 37 - 37 = 0

2x = 0

Divide both sides by 2:

2x/2 = 0/2

x = 0

Hence the value of  x from the expression is 2

Answer:

4 miles

Step-by-step explanation:

In 7 minutes he runs 1 mile

So in 28 minutes he runs 4 miles

How did I get this answer?

7×4=28

So 1×4=4

In ratios, when you times anything by something, you must do the same to the other part of the ratio.

Answer:

Hello there! The answer to this problem is that Bobby can run 4 miles in 28 minutes. If Bobby runs 1 mile in 7 minutes, we will have a table with two columns. On the left, we will have the number of miles, and on the right we will have the number of minutes.

miles - minutes

1 - 7

2 - 14

3 - 21

4 - 28

As the number of miles increases by 1, the number of minutes increases by 7. This is a ratio of 1:7. If it takes Bobby 7 minutes to run a mile, it makes sense that it will take him 28 minutes to run 4 miles because 28/7 = 4.

Explanation:

If there are n apples in a straight line, then there are n-1 gaps between the adjacent apples.

Having 8 apples will have 8-1 = 7 gaps between the apples.

Similarly, having 7 apples will have 7-1 = 6 gaps between those apples.

The 8 by 7 rectangle in the bottom level will have a 7 by 6 rectangle on the second level. The third level will have a 6 by 5 rectangle, and so on.

Here's a table to keep track of everything

[tex]\begin{array}{|c|c|c|} \cline{1-3}\text{Level} & \text{Dimensions} & \text{Number of apples}\\ \cline{1-3}\text{1} & \text{8 by 7} & \text{56}\\ \cline{1-3}\text{2} & \text{7 by 6} & \text{42}\\ \cline{1-3}\text{3} & \text{6 by 5} & \text{30}\\ \cline{1-3}\text{4} & \text{5 by 4} & \text{20}\\ \cline{1-3}\text{5} & \text{4 by 3} & \text{12}\\ \cline{1-3}\text{6} & \text{3 by 2} & \text{6}\\ \cline{1-3}\text{7} & \text{2 by 1} & \text{2}\\ \cline{1-3}\end{array}[/tex]
