Answer: 84

Step-by-step explanation:

The formula to calculate the number of ways to select x things from n things is given by :-

^nC_x=\dfra{n!}{{!(n-x)!}

Now, if 3 bananas are to be selected from a group of 9, then the number of ways  will be  

^9C_3=\dfrac{9!}{3!(9-3)!}=\dfrac{9\times8\times7\times6!}{6\times6!}=84

Hence, the  number of ways to select 3 bananas from a group of 9 =84

Speed typist #1 can type 95 words each minute. Speed typist #2 can type 98 words each minute. Working together, how many minutes
artcher [175]

Answer:

It will take them 15 minutes.

Step-by-step explanation:

1. Since you are given the information that the two typists are typing a certain amount of words in the same time frame (ie. one minute), you can add the two values together to obtain the total number of words the typists would type together in one minute:

95 + 98 = 193 words

2. To calculate how many minutes it would take them to type 2,895 words, you would simply take this total number of words and divide it by the number of words they collectively type in one minute (found in 1.). Thus:

2895/193 = 15

Therefor, it will take them 15 minutes to type 2,895 words.

Alekssandra [29.7K]

Answer:

check it

Step-by-step explanation:

“Lucynell don’t even know what a hotel is,” the old woman muttered. “Listen here, Mr. Shiftlet,” she said, sliding forward in her chair, “you’d be getting a permanent house and a deep well and the most innocent girl in the world. You don’t need no money. Lemme tell you something: there ain’t any place in the world for a poor disabled friendless drifting man.”

The ugly words settled in Mr. Shiftlet’s head like a group of buzzards in the top of a tree.
