Which of the following are the most compatible numbers for dividing 8,652 = 45?​

Answers

Answer:

2

Step-by-step explanation:

None of the given numbers are compatible for dividing 8,652 by 45.

What are compatible numbers?

Compatible numbers seem numbers that are simple to work with mentally and can be utilized to estimate or validate mathematical solutions. Compatible numbers are frequently selected based on how close they are to the numbers involved in the situation.

We can utilise divisibility principles to remove some alternatives when determining which integers are the most compatible for dividing 8,652 by 45.

The divisibility rule for 45 states that a number has to be divisible by both 9 and 5. As a result, we want to identify 9 factors that also divide 8,652.

The divisibility rule for 9 states that the sum of a number's digits must be divisible by 9 in order for the number to be divisible by 9.

So, add the figures 8,652 together: 8 + 6 + 5 + 2 = 21.

We can't divide 8,652 by 45 evenly since 21 isn't divisible by 9.

Therefore, none of the given numbers are compatible for dividing 8,652 by 45.

how do i solve this .75x4 – 8 = -12

Answers

assuming the .75x4 is .75 times x times for and not .75 times four...
Firstly, know you want x on its own.

So I’d start by adding 8 to both sides. This cancels out the -8:

.75x *4 - 8 = -12
+8 +8

= .75x * 4 = -4

Now divide by 4, both sides.
.75x * 4 = -4
———————
4

=.75x = -1

Finally, divide both sides by .75:

.75x = -1
—————
.75

= x = -1.33 (33 repeating) OR -4/3

But if you meant .75x^4 - 8 = -12 then here’s the answer.

First you add 8 to both sides, so:

75x^4 - 8 = -12
+8 +8

= .75x^4 = -4

Now divide both sides by .75:

.75x^4 = -4
——————
.75

= x^4 = -5.3333 OR -16/3

Now’s the harder part. We need to get rid of ^4 from x. Which means taking the root (both sides)...

An easier way to say this, and how I prefer to set it up, is + or - (-16/3)^(1/4)

You have the + or 1 part because the square root of something is always able to be positive or negative— as an easy example, 2*2=4 and -2*-2=4, so root of 4 could be -2 or 2. Anyways for this problem there aren’t any real solutions.

If your teacher is expecting you to use i in order to get the answers (for this last part, assuming they wanted .75x^4 and not .75x*4) then I can explain in the comments but it’s definitely harder than what I’ve shown here.

The volume of this cylinder is approximately ___ cubic cm.


Use ​ ≈ 3.14. Do not round your answer.

Answers

Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

            radius = 57 cm        height = 40 cm

area of a cylinder  =   π 57² cm² × 40 cm

                              =   π (57² × 40) cm³

                              =   π ( 57 × 57 × 40) cm³             57x57 = 399 + 2850 = 3249  

                              =   π (3249 × 40) cm³

                              =    129969π cm³      π = 3.14

Explain how to use the unit-factor method to convert 120 pounds to kilograms.

Hint: 1 kilogram=2.2 pounds

To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answers

The converted units is 120 pounds = 54.5 kilogram

How to convert the units?

As a general rule, we have:

1 kilogram=2.2 pounds

Multiply both sides by 120

120 * 1 kilogram=2.2 pounds * 120

Divide both sides by 2.2

120/2.2 * 1 kilogram=2.2 pounds * 120/2.2

Evaluate the products

54.5 kilogram= 120 pounds

Rewrite as:

120 pounds = 54.5 kilogram

Hence, the converted units is 120 pounds = 54.5 kilogram
