Answers

Answer:

16 >_ w ( a line under >)

Step-by-step explanation:

Inequalities help us to compare two unequal expressions. The inequality that means the weight of a cat is no more than 16 pounds is 16>w.

What are inequalities?

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

The average mass of an adult human is about 65 kilograms while the average mass of an ant is approximately 4×10−3 grams. The total human population in the world is approximately 6.84 billion, and it is estimated there are currently about 10,000 trillion ants alive. Based on these values, about how many times greater is the total mass of living humans compared to the total mass of all living ants? Round to the nearest whole.

Answers

Find total mass:

Human: 65 kg x 6,840,000,000 = 444,600,000,000 kg

Ants: 4x10^-3 = 0.004g

0.004 x 10,000,000,000,000,000 = 40,000,000,000,000g

Divide total grams by 1000 to get kegs:

40,000,000,000,000 /1000 = 40,000,000,000 kgs.

Divide total mass of humans by total mass of ants:

444,600,000,000 / 40,000,000,000 = 11.115

Mass of humans is 11.115 times more than ants.

Rounded to the nearest whole number = 11 times more.

Complementary angles

Answers

Answer:  x = 5

============================================================

Explanation:

The square marker indicates a 90 degree, or right angle.

The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.

Add up the smaller angles, set the sum equal to 90, and solve for x.

3x+75 = 90

3x+75-75 = 90-75 ....... subtracting 75 from both sides

3x = 15

3x/3 = 15/3 ..... divide both sides by 3

x = 5

---------------

If x = 5, then 3x = 3*5 = 15

Then we can see that 15+75 = 90 to help check our answer.

You bought some stock, and then the stock price went down by 17.2% from the purchase price. By what percentage would the price have to increase for the investment to be back to the original value?

Answers

Step-by-step explanation:

Let's pick some easy numbers for illustration.

Let x equal our initial stock purchase, and, say it was $100.

x = $100

The problem says it's value dropped by 17.2%. If x = 100 is 100% of our stock value the 17.2% less is

[tex]x - 0.172x = 0.828x[/tex]

So now our stock is worth 0.828(100) = $82.80.

Now how much of an increase do we need to get back to $100.

[tex]100 - 82.80 = 17.20[/tex]

So our base is $82.80 because our stock price dropped, we want to know what percent increase is $17.20 of $82.80

[tex]17.20 \div 82.80 = 0.2077[/tex]

Or 20.77% increase to get back to original price.

To make this generic, since $100 is not supplied information, substitute x for 100 and 0.828x for the amount of money dropped.

x = original stock value

[tex]x - 0.828x [/tex]

Is the amount of value lost, and to be regained in the second part of the question.

To find out what portion the decrease is of the new value

[tex] \frac{(x - 0.828x)}{0.828x} = \frac{0.172x}{0.828x} = 0.2077 [/tex]

Or 20.77%

It is 6.417.5 km from Indianapolis to London, England. The Flash can make this trip in 1
hour and 35 minutes. How fast is this in miles per hour?

Answers

Answer:

[tex]Speed = 2519.58 mph[/tex]

Step-by-step explanation:

Given

[tex]Distance = 6417.5km[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Required

Calculate the speed in miles per hour

Convert distance to miles

[tex]Distance = 6417.5km[/tex]

[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]

[tex]Distance = 3988.50217526\ miles[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Divide minutes by 60

[tex]Time = 1\ hr + 35/60[/tex]

[tex]Time = 1\ hr + 0.583\ hr[/tex]

[tex]Time = 1.583hr[/tex]

The speed is:

[tex]Speed = Distance/Time[/tex]

[tex]Speed = 3988.50217526/1.583 mph[/tex]

[tex]Speed = 2519.58 mph[/tex]


Halla el MCM de 63 y 77

Answers

Respuesta:

693

Explicación:

Tenemos que dividir ambos dígitos hasta que lleguen a 1.

No importa si uno de los números no se puede dividir, pero se debe iniciar desde los números más bajos: 2, 3, 4, 5, 7...

Cómo no hay una mitad exacta, empezaremos con tercia y continuaremos dividiendo.

63 ; 77 | 3  

21 ; 77  | 3  

7 : 77    | 7

1  ;  11    | 11

1  ;  1

Ahora que llegamos hasta 1, el MCM es la multiplicación de los números por los que hemos dividido a los dígitos. Solo falta multiplicarlos.
