Mathematics
1 answer:
Iteru [2.4K]3 years ago
5 0

Answer:

Step-by-step explanation:

(Tangent Length)^2 = y*(y + 11)   You are going to have to use the quadratic formula on this.

Tangent Length = 7

7^2 = y * (y + 11)

49 = y^2 + 11y  

0 = y^2 + 11y - 49

a = 1

b = 11

c = - 49

When you solve this quadratic equation you get

x1 = 3.40 which is the answer you go with.

x2 = -14.40 which can't be used. A negative length has no meaning.

On the map below, 14 inch represents one mile. Candler, Canton, and Oteen are three cities on the map.

Map_problem_figure_aff1d9be1f7b39bb6155b3bcf9b3ddd4

If the distance between the real towns of Candler and Canton is 9 miles, how far apart are Candler and Canton on the map?

If Candler and Oteen are 312 inches apart on the map, what is the actual distance between Candler and Oteen in miles?

Commentary

The purpose of this task is for students to translate between information provided on a map that is drawn to scale and the distance between two cities represented on the map. This task is a very straightforward application of the mathematics described in 7.G.A.1. This task would be appropriate for assessment.

Solutions

Solution: 1

A distance of nine miles means 9 quarter inches on the map. This is

9×14=94

or 214 inches between Candler and Canton on the map.

Map_problem_a_425ac563f0de413ec7618e8fe79c1b90

How many 14 inches are in 312 inches? To find this, we divide:

312÷14=72×41=14

So it is 14 miles between Chandler and Oteen.

Kevin has had a checking account for a month. As he reconciles his account, Kevin notices that the dates on his check register d
Nataly_w [17]

Answer:

Option D is correct answer.

Step-by-step explanation:

The correct answer is option D- "The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when its written". 

It takes up to 3-4 business day to cash a check. So, Kevin might have entered the date when he wrote the check but as the check was cashed a few days after, the bank would have entered that date. So, it caused the confusion.

Options A, Band C are not correct as if it would have been option A, Kevin would have seen it before calling the bank. It cannot be option B either as banks don't do such silly mistakes. Option C cannot be true either as this type of error has nil chances to occur.
