Answer 1
Answer: Q1. The answer is d) 13 to 18

There are 13 pens and 18 pencils. Ratio of pens to pencils can be written as:
pens : pencils

Since pens = 13 and pencils = 18, then 
pens : pencils = 13 : 18

Or in other words, ratio of pens to pencils is 13 to 18. Thus, choice d) is correct.


Q2. The answer is C.5 to 8

There are 12 tulips and 20 roses. The total number of flowers is 12 tulips + 20 roses = 32 flowers. Ratio of roses to the total number of flowers can be written as:
roses : total flowers

Since roses = 20 and total flowers = 32, then 
roses : total flowers = 20 : 32

Now, let's simplify 20 to 32 ratio:
20 : 32 = (20 / 4) : (32 / 4) = 5 : 8 

Or in other words, ratio of roses to the total number of flowers is is 5 to 8. Thus, choice C. is correct.


Q3. The answer is 3 : 4

There are 30 one-story homes and 24 two-story homes. Ratio of two -story homes to one-story homes can be written as:
two-story homes : one-story homes

Since one-story homes = 32 and two-story homes = 24, then 
two-story homes : one-story homes = 24 : 32

Now, let's simplify 24 to 32 ratio:
24 : 32 = (24 / 8) : (32 / 8) = 3 : 4

So, the ratio of one-story homes to two-story homes is 3 to 4.


Q4. The answer is 

There are 16 trading cards and 2 wildlife cards. Ratio of wildlife cards to total trading cards can be written as:
wildlife cards : trading cards

Since trading cards = 16 and wildlife cards = 2, then 
wildlife cards : trading cards = 2 : 16

Now, let's simplify 2 to 16 ratio:
2 : 16 = (2 / 2) : (16 / 2) = 1 : 8

So, the ratio of wildlife cards to total trading cards is 1 : 8



Q5. The answer is

There are 3 cobblers. The total number of baked goods is 12 cookies + 9 pies + 8 cakes + 4 tarts + 3 cobblers = 36 baked goods.  Ratio of the total number of baked goods to cobblers can be written as:
baked goods : cobblers

Since baked goods = 36 and cobblers = 3, then 
wildlife cards : trading cards = 36 : 3

Now, let's simplify 36 to 3 ratio:
36 : 3 = (36 / 3) : (3 / 3) = 12 : 1

So, the ratio of the total number of baked goods to cobblers is 12 : 1

What is the difference between (-58) and (+35) ?

Answers

To do this question, you are best splitting it into two halves: getting to 0, and then 35
Starting at -58, we want to get to 0
-58 + 58 = 0
Then, we get to 35 from 0
0 + 35 = 35
Now, add the two values together
58 + 35 = 93
The difference is 93
If the equation is -58-35, the answer would be -93. It would be -93 because you would KEEP THE SIGN OF THE BIGGER NUMBER (Whether it's - or +) IF THE SIGN IS THE SAME YOU ADD (If the sign is - and - or + and +) IF THE SIGN IS DIFFERENT YOU SUBTRACT (So that means if you have + and - or - and +).

I hope this helps!

16,500 rounded to the nearest ten thousand

Answers


The next larger ten thousand is  20,000 .
The next smaller ten thousand is  10,000 .
16,500  is closer to  20,000  than it is to  10,000 .
So  20,000  is the nearest ten thousand.
16,500 rounded to the nearest ten thousand would be 20,000 because 6 is bigger the 1,2,3, and 4 so you round up. so 1 rounded up one would be 2

What is the answer to the equation 5x=2x+20?

Answers


I don't know.  But I know how to find it.  Let's work it out together:

                                              5x  =  2x + 20

Subtract  2x  from each side:    3x  =  20

Divide each side by  3 :              x  =  20/3  or    ( 6 and 2/3 ).
5x = 2x + 20 \n subtract--------\ \textgreater \ -2x \n 3x = 20 \n Divide -----\ \textgreater \ 3x \n \n x = 6 (2)/(3)
