Answer:
Step-by-step explanation:
ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.
so y is the same as 110
and 180 - 110 is 70, so x and z are equal to 70.
i hope this helped you :)
There will be excactly 400 fiction books. The ratio of fiction to all is 4 to 9, or 4 to 900.
Set up a proportion: 3/10= x/80. Then if you multiply 10 by 8, you get 80 on both sides, But, If you do it to the top, you also have to do it to the bottom, so the anser is 3 x 8 , or 24.
Answer:
1155
Step-by-step explanation:
We need to determine 55% of 2100 now and the procedure explaining it as such
Step 1: In the given case Output Value is 2100.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 2100 = 100%.
Step 4: In the Same way, x = 55%.
Step 5: On dividing the pair of simple equations we got the equation as under
2100 = 100% (1).
x = 55% (2).
(2100%)/(x%) = 100/55
Step 6: Reciprocal of both the sides results in the following equation
x%/2100% = 55/100
Step 7: Simplifying the above obtained equation further will tell what is 55% of 2100
x = 1155%
Therefore, 55% of 2100 is 1155
