In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4of an hour. What is Mila's average swimming speed?

Answers

Answer 1

Answer: 2000m/h

Step-by-step explanation:

speed = distance/time

milas distance was (2/3).(750 m) = 500 m, so her speed was (500 m)/(1/4) = 2000 m/h

Use known logical equivalences to prove that a → (b → c) is logically equivalent to (a ^ b) → c.

Answers

Answer:-

a ∨ ( b ∨ c )    ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

Step-by-step explanation:

Explanation :-

we know that   b→ c ⇔ b∨c

Replacing b→ c ⇔ b ∨ c , we get

               a → b ∨ c ,

By the same rule b→ c ⇔ b∨c

                     ⇒   a ∨ ( b ∨ c )

Now

 a ∨ ( b ∨ c )    ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

Margaret drove to a business appointment at 90 mph. Her average speed on the return trip was 80 mph. The return trip took 1/4
hr longer because of heavy traffic. How far did she travel to the appointment?

Answers

Distance = speed x time

Let the time to the appointment = x

The time home would be x + 1/4 hour

set up an equation you have 90x = 80(x + 1/4)

Simplify:

90x = 80x + 20

Subtract 80x from both sides:

10x = 20

Divide both sides by 10:

x = 2 hours

Distance = 90 x 2 = 180 miles

Answers

Answer: 15/32

Step-by-step explanation:

The data that we have is:

5/8 of the vegetable sold where green.

of theses 5/8, 3/4 were string beans.

Then the 3/4 is applied to the 5/8 of green vegetables.

Then the fraction (of the total number of vegetables) that were string beans was:

F  = (3/4)*(5/8) = (3*5)/(4*8) = 15/32

As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million. In mid-2016, what percent of the world's population was the Country A population? Round your answer as a percentage to one decimal place.

Answers

Answer:

The percentage of country A population to the world population

= 3.05%

Step-by-step explanation:

Country A population as of 2016

= 226 million

= 226000000

The world population as of 2016

= 7.4 billion

= 7400000000

The percentage of country A population to the world population

= Country A population /The world population

The percentage of country A population to the world population

= 226000000/7400000000

The percentage of country A population to the world population

= 0.03054

Now multiplying by 100

= 3.05%

The percentage of country A population to the world population is  3.05%

Given that,

As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million.

Based on the above information, the calculation is as follows:

[tex]= 226000000\div 7400000000[/tex]

PLEASE ANSWER ASAP!!!! WILL GIVE BRAINLIEST!

Answers

Answer:

A and D

Step-by-step explanation:

Given that the area of a square = 400 units² = s²

Where s is one side length of the square.

It means that the side length (s) = √400 = 20

If the length of each side length increase by 1 units, new side length = 21 units

Area of new square = 21² = 441

The following statements would be true if the side length was increased by 1 units:

A. "The area of the square would be a rational number"

441 is a rational number, because a rational number is a quotient of two integers.

441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441

D. "The area of the square would be a perfect square".

A number is considered a perfect square if it can be expressed as a product of two equal integers.

441 can be expressed as 21*21

Step-by-step explanation:

3^3+4-7

27+4-7

24

The value after simplifying the expression 3² + 8 ÷ 2 - (4 + 3) is 6 by using PEMDAS rule.

To simplify the expression 3² + 8 ÷ 2 - (4 + 3), follow the order of operations (PEMDAS/BODMAS):

P - Parentheses first

E - Exponents (i.e., powers and square roots, etc.)

MD - Multiplication and Division (left to right)

AS - Addition and Subtraction (left to right)

Start with the exponent:

3² = 3 × 3 = 9.

Next, perform the division:

8 ÷ 2 = 4.

Now, deal with the parentheses:

(4 + 3) = 7.

Finally, perform the addition and subtraction from left to right:

9 + 4 - 7

= 6.

So, the simplified expression is 6.
