Answer:
1) 47
2) 4
Step-by-step explanation:
Complimentary = 90 degrees
1) 43 + ? = 90
? = 47
2) 86 + ? = 90
? = 4
1. Tess is making 12 bows.
2. 100 time as 12 bows = 100 × 12 = 1200 bows
3. In exponent form ; 12 × 10²
Given : Number of bows Tess makes = 100 times as the of x
Let the number of bows Tess makes be x
Thus the number of bows Tess is making is 12.
100 times as many means the number which we have calculated should be multiplied by 100.
thus the number as w2e have found out is 12
so multiplied by 100 will give us 1200
Exponential form means that the given number should be expressed in the form of 10.
As the number which is given to us is 1200n
thus in exponential form we can write it as 12 multiplied by 10 raise to the power as the number of zeros of present.
Here then number of number of zeros is 2
thus 10 raised to the power 2.

Alright, so we have 1.3/0.0338. Since it's easier (in my opinion) to work with whole numbers, we can multiply the fraction by 10000/10000 to get 13000/338. With a bit of guess and check, we can see that
338*30=338*3*10
1 2 (what I carry is at the top)

____
1114
Multiplying that by 10, I get 11140, which isn't enough. Trying 338*40, which is 338*4*10, we can add 338 to 338*3 to get 338*4 to get

1114
+338
____
1462
Multiplying that by 10, we get 14620, which is more than 13000 - something we don't want. Repeating this for 338*35 (which is 338*3.5*10, and 3.5 is 3*338+338/2)=11830 and which isn't enough, we then move on to something between 35 and 40 (the number doesn't matter), say 39. 338*39=338*3.9*10, and 338*3.9 is 338*3+338*9/10, and
338*39 results to 13182, which is more than 13000 , but only by a tiny bit, so we can try 38 using the same method, getting 12844, which is smaller, so we know it's between 38 and 39. Finding the difference between 13000 and 12844, we get 13000-12844=156 and the answer is therefore 38+156/338
The value of the digit is 2 because the value of the 3 is 30 (tens) and if you go one place down you are in the ones
