Answer:
The answer is C (2:1)
Step-by-step explanation:
1. The greatest common factor of 8 and 4, is 4. We need to divide both numbers by the GCM, 4.
8 / 4 = 2
4 / 4 = 1
Therefore, the answer is 2:1 (C)
Answer:
11) 2
12) 1
13) 6
14) 6
15) m<1=58°
m<2=122°
m<3=58°
m<5=122°
m<6=58°
m<7=122°
m<8=58°
Step-by-step explanation:
11) 2
12) 1
13) 6
14) 6
15) m<1=58°
m<2=122°
m<3=58°
m<5=122°
m<6=58°
m<7=122°
m<8=58°
To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster
Answer:
6.67
Step-by-step explanation:
20/3=6.6666666
Rounded to two decimals is 6.67
(the 6 is rounded up because it is above 4)
