1. we have to find what number lie at A and B , and that too between and 1 and 2 , so these two numbers must be decimal numbers!! So let's find the number of scales between 1 and 2 , we get 8 scales !! So the question is how much place 1 scale will occupy ?? we have to find certain numbers between 1 and 2 , suppose between 1 and 2 we have 1 unit and those 1 unit occupies 8 scales !! so much place 1 scale occupies ?? to get it divide 1 by 8 and we get 0.125 !! so between 1 and 2 ,each blank space or scale occupies 0.125 unit!! now what numbers lie at A ? count the number of scale between 1 and A , we get 3 scales ! now multiply 3 by 0.125 , we get 0.375 , add 1 to 0.375 , we get 1.375 !! hence 1.375 lies at A ! now we have to find which number lies at B ? count the number of blanks or scale , we get 4 ! multiply 4 by 0.125 and we get 0.5 ! add this 0.5 to 1 , we get 1.5 ! therefore the number 1.5 lies at B !!
2. for 2nd number solution refer to the attachment! !
Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees
Answer:
{6,7,8,9,10}
Step-by-step explanation:
Solve the inequality using inverse operations.
This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.
Answer: 3.16, 8, 9, 12
Step-by-step explanation:
= 3.16
2^3 = 2 * 2 * 2 = 8
|-9| = 9
1.2 x 10^1 = 1.2 * 10 = 12
3.16, 8, 9, 12
