Rachel's unit rate is : 2.80
Kevin's is: 3.20
( you simply divide the dollar amount by the rolls of tape-- 33.60÷ 12)
Therefore, Kevin's is greater than Rachel's.
Rachel paid $33.60 for 12 rolls.
Unit rate paid by Rachel =
= 2.8
From table,
Kevin paid $6.40 for 2 rolls.
Unit rate paid by Kevin =
= 3.20.
Check:
Kevin bought 5 rolls for $16
5 × 3.2 = 16
He also bought 8 rolls for $25.6.
8 × 3.2 = 25.6.
If we compare the unit rates paid by Rachel and Kevin,
Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.
Answer:
B
Step-by-step explanation:
in a 30,60,90 triangle the longer leg is rt3 times the value of the shorter leg and the hypotenuse is 2 times greater than the shorter leg.
Answer:
Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360
.</u>
The option is
4. 270≤Ф≤360
Step-by-step explanation:
When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.
For Example.
Quadrant I - 0 to 90°
Quadrant II - 90° to 180°
Quadrant III - 180° to 270°
Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360 )
Hence,Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360
.</u>
When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.
Quadrant IV - 0° to -90°
Quadrant III - - 90° to -180°
Quadrant II - -180° to -270°
Quadrant I - -270° to -360°
