Yuri [45]3 years ago
7 0

Hello there!

To find the GCF, we must list all the factors and then just spot the greatest factor.

28: 1, 2, 4, 7, 14, 28.

210 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70.

So 14 is the GCF. Hope this helps you!

Which choice provides the best evidence for the
vodka [1.7K]

Correct option is B, Lines 39-42 ("Normally . . . community")

The "matter of urgency," as Akira explains in lines 39–42, is that he has "an opportunity to go to America, as dentist for Seattle's Japanese community." Chie's response to Akira's marriage proposal is necessary for him to determine whether or not to take the position in Seattle.

The answers to the previous question are not well supported by the evidence in Choices A, C, and D. Choice A is wrong since Akira apologizes for disturbing Chie's peaceful evening in line 39. Lines 58–59 discuss the gravity of Akira's demand, not its immediacy, hence option C is incorrect.

Line 73 merely demonstrates that Akira's suggestion "startled" Chie, not why his request is time-sensitive, hence option D is incorrect.

Here's another question with an answer similar to this Chie and Akira:

a football team had 50 players at the start of the season, but then some players left the team. After that, the team had 42 play
wel

Answer:

50 = p + 42

Step-by-step explanation:

The unknown part of this equation is the variable p, the number of people that left. So you want to add p to 42 and that will give you the total number of football players, which is 50. In order to get p, you need to get it by itself and make it equal something. Subtract 42 from both sides and you are stuck with 50-42 = p

p = 8

The times for completing one circuit of a bicycle course are normally distributed with
Sonja [21]

Answer:

The answer is 76.9 rounded or rounds.

Step-by-step explanation:

Solution

Given that:

Mean = μ = 72.5

Standard deviation = σ = 6.5

Now

By applying the standard normal table we have the following:

P(Z < z) = 75%

= P(Z < z)

= 0.75

Thus

z =0.67 by using the standard normal z table

Applying the  z-score formula we have:

x = z * σ + μ

x = 0.67*6.5+72.5

x= 76.855 ≈ 76.9

Therefore the cutoff time is 76.9 rounds.

at a movie theatre, child admission is $6.40 and adult admission is $9.70. on Wednesday, 128 tickets were sold for a total sales
grandymaker [24]

Answer: 74 adult tickets were sold on Wednesday.

Step-by-step explanation:

Let x represent the number of child admission tickets sold on Wednesday.

Let y represent the number of adult admission tickets sold on Wednesday.

On Wednesday, 128 tickets were sold. It means that

x + y = 128

At the movie theatre, child admission is $6.40 and adult admission is $9.70. The total ticket sales on Wednesday was $1063.40. It means that

6.4x + 9.7y = 1063.4- - - - - - - - - - 1

Substituting x = 128 - y into equation 1, it becomes

6.4(128 - y) + 9.7y = 1063.4

819.2 - 6.4y + 9.7y = 1063.4

- 6.4y + 9.7y = 1063.4 - 819.2

3.3y = 244.2

y = 244.2/3.3

y = 74

x = 128 - y = 128 - 74

x = 54
