What is the factor of 36

Answers

the square root rounded up to the nearest integer, 6.
testing the values 1 through 6 for division into 36 we find factors of 36 which are : (1, 36)
(2, 18)
(3, 12)
(4, 9)
(6,6)
or in other words the sets would be : 1, 2 , 3, 4 , 6 , 9 , 12 , 18 , 36

1 and 36), (2 and 18), (3 and 12), (4 and 9), (6 and 6) or the set 1, 2, 3, 4, 6, 9, 12, 18, 36.

A health insurance payment of $34.55 was deducted from ms. Donaldson's earnings for the week. After the insurance deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms. Donaldson received?

Answers

I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10

So the 34.55 were deduced from this number, and the remaining amount was:

907.10-34.55=872.65

After this, further 28% were deduced, which means that 100-28=72% were left.

And this is:72%*872.55= 628.236 (which we round to 628.24!)

Answer: the answer would be 628.24!

Kara answered 10% of the 40 questions on a Chinese test incorrectly. How many questions did Kara answer correctly?

Answers

Always read the question very carefully as it contains a lot of vital information's. Based on those information's the answer to the question can be easily deduced.
Total number of questions given in a Chinese test = 40
Percentage of questions incorrectly answered by Kara = 10%
Then
Number of questions incorrectly answered by Kara = (10/100) * 40
= 4
Then
The total number of questions correctly answered by Kara = 40 - 4
= 36
From the above deduction we can clearly see that Kara answered 36 questions correctly among the total of 40 Chinese questions that were given.

The answer to your problem is 36, you take 40 tiems 010 then subtract that and you get 36.

Find the distance between the points (6, 5 square root 2) and (4, 3square root 2).

Answers

For this case we use the distance formula between two points.

We have then:

$d=√((x2-x1)^2+(y2-y1)^2)$

Substituting values in the given equation we have:

$d=\sqrt{(6-4)^2+(5√(2)-3√(2))^2}$

Rewriting the equation we have:

$d=\sqrt{(2)^2+(2√(2))^2}$

$d=√(4+8)$

$d=√(12)$

$d=√(3*4)$

$d=2√(3)$

Answer:

The distance between the points is:

$d=2√(3)$

The distance would be 2√3 , in other words it is 2 square root 3

A dartboard has a diameter of 12 inches. What are its radius and circumference? Round to the nearest hundredth. Use 3.14 for π. The radius is inches. The circumference is approximately inches.

Answers

Radius=Diameter/2
=12/2
=6 inches

Circumference=2*3.14*radius
=2*3.14*6
=37.70 inches

Answer:

1) 12in

Step-by-step explanation:

The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.
