3 1/4 ÷ 1 3/8
(If you don't know what (⬆) that is it is written as 3 and 1/4 divided by 1 and 3/8)

Answers

To answer this, both the divisor and dividend need to be converted to improper fractions. The first would be 13/4 and the second would become 11/8, so now the whole question reads as "[13/4] / [11/8]". To continue, the divisor needs to have its reciprocal found, which is 8/11 in this case. Then, the whole problem is multiplied: 13/4 * 8/11 gives 104/44 if both the numerators and denominators are multiplied. Reducing this gives 2 + 16/44, or 2 + 4/11 when fully reduced.

Which numbers should be multiplied to obtain 175^2 − 124^2?

A. 51 and 299
B. 51 and 51
C. 2601 and 2601
D. 30501 and 30749

Answers

Hello,

Answer A

175²-124²=(175+124)(175-124)=299*51

Final answer:

The numbers that should be multiplied to obtain 175² - 124² are 51 and 299. This is due to the algebraic concept of a difference of squares.

Explanation:

The mathematical expression 175² - 124² can be represented as the difference of squares. The difference of squares is a special case in algebra where a² - b² can be factored into (a + b)(a - b). So, in this case, we can represent 175² - 124² as (175 + 124)(175 - 124).

Hence, the numbers that should be multiplied in this case are 51 and 299. Therefore, the correct answer is option A: 51 and 299.

The pitcher for the robins throws a baseball at 90.0 miles per hour. The pitcher on the bluebirds throws a baseball 121 feet per second. Which pitcher throws a baseball faster?

Answers

There are 5,280 feet in a mile, and 3,600 seconds in an hour. We want to bring both of these down to the same measurements. There are 475,200 feet in 90 miles. Divide 475,200 by 3,600. The result is 132, which is larger than 121. The pitcher for the robins throws faster.

Answer:

The pitcher of robins throws a baseball faster.

Step-by-step explanation:

Speed of base ball thrown by the pitcher for the robins = 90.0 mile/hour

1 mile = 5280 feets

1 hour = 3600 seconds

[tex]90.0 mile/hour=\frac{90.0\times 5280 feet}{3600 s}=132 feet/s[/tex]

Speed of base ball thrown by the pitcher for the bluebirds= 121 feet/s

132 feet/s > 121 feet/s

The pitcher of robins throws a baseball faster.

tan (A+B) = sin(A+B)/cos(A+B)  with A+B = -53.13 + 112.62 = 59.49

Which of the following numbers is irrational? a fraction with numerator negative 9 and denominator 5, a fraction with numerator square root of 5, a fraction with numerator 7 and denominator 3, square root of 9

Answers

A fraction with numerator -9 and denominator root 5.

With the other scenarios, every number is rational. All whole numbers/integers are rational. The root of 9 is 3, which is whole and rational. Negative numbers are also rational so long as they are whole/an integer. This allows for you to be able to write a fraction using only integers (or with decimals that have a finite end).

However the root of 5 goes on infinitely.

Answer:

The answer is square root of 5.

Step-by-step explanation:

Irrational numbers are those that cannot be expressed as a ratio of two integers.

And when we express these in decimal form, they have an infinite and nonrecurring expansion like the number π and the square root of 2.

The answer is square root of 5. This is because the square root of 5 will never result in a number that will be exact.

he Mitchell family is renting a boat for the day. The boat rental has a flat fee of $100 plus $20 for each hour. They have to pay for a whole hour even if they are not out on the lake for a whole hour. For example, if they rent the boat for 3 and one-half hours, they have to pay for 4 hours. If they want to spend $250 or less on the boat rental for the day, how many hours can they rent the boat? Write an inequality and solve.

They can rent the boat for 7 hours for $ 240 in total.

Since the Mitchell family is renting a boat for the day, and the boat rental has a flat fee of $ 100 plus $ 20 for each hour, and they have to pay for a whole hour even if they are not out on the lake for a whole hour, to determine, if they want to spend $ 250 or less on the boat rental for the day, how many hours can they rent the boat, the following calculation must be performed:

Fixed cost + Variable cost multiplied by the number of hours = Final cost 100 + 20X = 250 20X = 150 X = 150/20 X = 7.5 100 + 20 x 8 = 100 + 160 = 260 100 + 20 x 7 = 100 + 140 = 240

So they can rent the boat for 7 hours for $ 240 in total.

Answers

He worked a total of 405 minutes. Hope this helps!

Final answer:

The security guard worked for 6 hours and 45 minutes, this is because 0.75 of an hour is equivalent to 45 minutes.

Explanation:

In the context of this question, the security guard logged 6.75 hours on his shift. This figure is given in decimal format. To convert this into hours and minutes, you need to understand that .75 of an hour is three quarters of 60 minutes. So, 0.75 x 60 minutes is 45 minutes. Therefore, the security guard worked for 6 hours and 45 minutes.

This is equivalent to 6 hours and 45 minutes. In decimal form, 0.75 represents three-quarters of an hour, which is 45 minutes. So, he worked for 6 hours and 45 minutes.

5.5 g/m^2 x 5.87 x 10^5 m^2 = 3.23 x 10^6 g 
3.23 x 10^6 g x 1kg/10000 g = 3.23 x 10^3 kg

Answer:

4008.10 kg

Step-by-step explanation:

We have been given that a vineyard has 165 acres of chardonnay grapes. a particular soil supplement requires 6.00 grams for every square meter of vineyard.

We know that 1 squared km equals 247 acres.

[tex]\text{165 acres}\times\frac{\text{1 km}^2}{\text{247 acres}}[/tex]

[tex]165\times\frac{\text{1 km}^2}{247}[/tex]

[tex]0.6680161943319838\text{ km}^2[/tex]

We know 1 square km equals 1000000 meters.

[tex]0.6680161943319838\text{ km}^2\times \frac{1000000\text{ m}^2}{\text{ km}^2}[/tex]

[tex]0.6680161943319838\times 1000000\text{ m}^2[/tex]

[tex]668016.1943319838\text{ m}^2[/tex]

Now, we will multiply 6 by [tex]668016.1943319838\text{ m}^2[/tex].

[tex]668016.1943319838\text{ m}^2\times \frac{\text{6 grams}}{\text{m}^2}[/tex]

[tex]668016.1943319838\times \text{6 grams}[/tex]

[tex]4008097.1659919028\text{ grams}[/tex]

[tex]4008097.1659919028\text{ grams}\times \frac{1\text{ kg}}{\text{1000 grams}}[/tex]

[tex]4008.09716599190281\text{ kg}[/tex]

How many years difference is there between 250 ce and 250 bce?

Answers

500 years

250 ce ----> 0 ce = 250 years
0 ce ----> 250 bce = 250 years

250+250= 500 years

There are 500 years between 250 CE and 250 BCE

Years that are denoted as BCE are counted backwards until they get to 0 after which years are then denoted as CE and these ones count upwards.

This means that to find the difference between these two years, you must first count from 250 BCE to 0 and then from 0 to 250 CE.

250 BCE to zero = 250 years

Zero to 250 CE = 250 years

Then sum them up:

= 250 + 250

= 500 years

There is therefore a difference of 500 years between these two years.
