Tom swam to the bottom of a swimming pool that was 9 feet deep and he touched
the bottom. He swam back to the surface. How many feet did Tom swim?

Answers

Answer:

18 feet

Step-by-step explanation:

9 x 2 = 18

Answer: 18 feet

Reason: he swam 9 feet going down the pool, but he didn’t just stay under there, he swam back up to the surface.
Thus we can 9 (feet for swimming to the bottom) plus 9 ( feet for swimming to the top).
In mathematical term we can say this in two ways.
9 + 9 = 18
Or
9 x 2 = 18

You want to save $10,000 to buy a new car You doposit 6500in an account earning 7.5% simple interest. After how long will you have enough money
in the account to purchase the car? Round your answer to the nearest whole number

Answers

Answer:

After 7.5 years we will have enough money in the account to purchase the car.

Step-by-step explanation:

Amount needed to be saved = $10000

Principal = $6500

So, Simple Interest = $3500

Rate of Interest = 7.5%

= 0.075

Now, Simple Interest = Principal × Rate × Time

⇒ 3500 = 6500 × 0.075 × Time

⇒ 3500 = 487.5 × Time

⇒ Time = 7.18 years ≈ 7.5 years

Hence, after 7.5 years we will have enough money in the account to purchase the car.

Step-by-step explanation:

For the sum of (5.2 x 10^4 ) and (6.95 x 10^4 ) in scientific notation, why will the power of 10 be 10^5 ?

Answers

Answer:

12.15 *10^4

=1.215 *10^5

it must be like that so as to express it in standard form

The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The numbers in the scientific notation will be given as,

(5.2 × 10⁴) and (6.95 × 10⁴)

Then the sum of the numbers will be

⇒ (5.2 × 10⁴) + (6.95 × 10⁴)

⇒ (5.2 + 6.95) × 10⁴

⇒ 12.15 × 10⁴

The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

Explain when it is appropriate to use a benchmark percent in solving a problem.

Answers

Answer:

The most common benchmark percents are 0%, 10%, 25%, 50%, 75% and 100%.

These benchmark values are sometimes used when estimating a solution involving percentages.

Real-World Example

If an item costs $36.00 and there is a 7% sales tax, the benchmark of 10% can be used to mentally estimate the sales tax of the item.

10% of 36, done mentally, is 3.6.

Since 7% is a bit less than 10%, the sales tax will be a bit less than $3.60.Step-by-step explanation:

The perimeter of this shape is 30 feet. What is the length of the missing side?

Answers

Answer:

The answer is 4ft.

Step-by-step explanation:

If you add:

7ft + 3ft + 5ft + 11ft = 26ft

Then if you take away the whole perimeter of the shape by the sides added so far:

30ft - 26ft

It would equal:

30ft - 26ft = 4ft

4ft is the answer.

The value of the length of the missing side is 4 ft and this can be determined by using the arithmetic operations.

Given :

The perimeter of this shape is 30 feet.

The following steps can be used in order to determine the length of the missing side:

Step 1 - The arithmetic operations can be used in order to determine the length of the missing side.

Step 2 - Let the length of the missing side be 'x'.

Step 3 - So, the perimeter of the given figure is given below:

[tex]30 = x+ 7 +3+5+11[/tex]

Step 4 - Simplify the above expression in order to determine the value of 'x'.

[tex]x=30-26\\x = 4[/tex]

So, the value of the length of the missing side is 4 ft.
