Answer:
z = 72°
Step-by-step explanation:
Complimentary angles sum to 90° , thus
z + y = 180, that is
z + 18 = 90 ( subtract 18 from both sides )
z = 72°
Remove the radical by raising each side to the index of the radical. a = √ 3 , − √ 3 a=3,-3 a ≈ 1.73205080 , − 1.73205080
Answer:
6750:9000*100 =
(6750*100):9000 =
675000:9000 = 75
Now we have: 6750 is what percent of 9000 = 75
Question: 6750 is what percent of 9000?
Percentage solution with steps:
Step 1: We make the assumption that 9000 is 100% since it is our output value.
Step-by-step explanation:
6750:9000*100 =
(6750*100):9000 =
675000:9000 = 75
Now we have: 6750 is what percent of 9000 = 75
Question: 6750 is what percent of 9000?
Percentage solution with steps:
Step 1: We make the assumption that 9000 is 100% since it is our output value.
-x+2 > 1
-x+2+x > 1+x .... add x to both sides
2 > 1+x
x+1 < 2
x+1-1 < 2-1 ... subtract 1 from both sides
x < 1
After solving for x, we get x < 1
To graph this, plot an open circle at 1 on the number line and shade to the left of this value. The open circle indicates that 1 is not part of the solution set.
If your teacher requires you to graph this on an xy grid, then draw a vertical line through 1 on the x axis. Make this vertical line a dashed line. Then shade the entire region to the left of this dashed line. Any point in this shaded region will have an x coordinate that is less than 1. The dashed line acts like the open circle. The dashed line tells the reader "any point on this dashed line is not part of the solution set"
Answer:
30 students
Step-by-step explanation:
Since 18 divided by 30 is .6, you convert .6 to 60% by moving the decimals two places to the right. Hope this helps.
