Every prime number greater than 10 has a digit in the ones place that is included in which set of numbers below?

### Answers

The numbers are all prime and odd numbers

11, 13,17,19,23,29,31,37,

so the numbers are 1,3,7,9

because

2 is even and if it ends in 2 then divisible by 2

this crosses out all the even numbers :2,4,6,8

if it ends with 5 then it is divisible by 5 cross 5 out

so the numbers are 1,3,7,9

if the number ends with these number that doesn't mean that it is always prime exg 21 is not prime, 49 is not prime

so the numbers 1,3,7,9

N^2+16n+60 over 36-n^2

### Answers

Factor

36-n^2 is difference of 2 perfect squares

a^2-b^2=(a-b)(a+b)

6^2-n^2=(6-n)(6+n)

factor

n^2+16n+60

find what 2 numbers multiply to 60 and add to 16

factors of 60=2,2,3,5

the numbers are 10 and 6

so factored out

(x+6)(x+10)

(x+6)=(6+x)

so the equation is

[(x+6)(x+10)]/[(6+x)(6-x)]=[(6+x)/(6+x)] times (x+10)/((6-x)=1 times (x+10)/(6-x)

the answer is (x+10)/(6-x)

Using the order of operations rule, solve the following: 12 ÷ 2 + 4 – 2 × 3 = ? A. 24 B. 36 C. 0 D. 4

### Answers

The answer is D, because you have to divide 12 by 2 so you get 6 then 2 times 3 to get 6, so now you should have 6+4-6 which will then become 10-6 which equals 4

### Answers

What is 8/10 as hundredths in fraction form and decimal form?

### Answers

In hundreths in fraction form, you want 100 on the denominator (bottom)

in order to do this, multiply the top and the bottomnumber by 10

8/10=80/100

to get to decimal form, since your fraction is already out of 100, take the 80 and put a decimal two places to the right

80->.8

Answer:

80/100 and 0.8

Step-by-step explanation:

You would do 8/10 and multiply both by 10 and that would give you 80/100. Mainly because 10x10 is 100 and 8x10 is 80.

To get the decimal form, divide 8 by 10 and it should give you 0.8 just like that. C:

Multiply. Write in simplest form. Identify the two whole numbers between which the product lies 5 x 6/8 and 2 x 9/10

### Answers

We have to multiply those numbers and to write it in the simplest form: 5 * 6/8 = 5 * 3/4 = 15/4 = 3 3/4. Another product is: 2 * 9/10 = 18/10 = 9/5 = 1 4/5. Then we will identify the 2 whole numbers between the product lies. Answer: For 15/4 ( equal to 3 3/4 ) those numbers are 3 and 4. For 9/5 (equal to 1 4/5 ) those numbers are 1 and 2.
