Rzqust [24]

Answer: He was 1 minute 28 seconds faster.

Step-by-step explanation:

Hi, to answer this question we simply have to subtract Frankie's time yesterday (29 minutes 49 seconds) to his normal time (31 minutes 17 seconds)  

Mathematically speaking:  

31m 17s - 29m 49s =

(31m-29 m) (17s-49s)=

2m -32s=

1m 60s -32s=

1m 28s

He was 1 minute 28 seconds faster.

Find Percent of a Number - Instruction - Level F
dimaraw [331]

Answer:

Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Step-by-step explanation:

Sierra: 7/28 = 1/4

1/4 written as a percentage is 25%

Aubrey: 5/25 = 1/5

1/5 written as a percentage is 20%

25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Hope this helps ;)
