Answer:

A. Accurate. The triangles are similar and the congruent angles are listed in corresponding order.

Step-by-step explanation:

Retrieving the rest of this question, We can add to that:

Which best describes the accuracy of Daniela’s solution?

Two triangles are similar if and only if their three vertex angles are congruent.

Considering the sum of interior angles to be equal to 180.

Examining each triangle we have:

$\\\angle T+\angle R+\angle S=180\\\angle D+\angle A+\angle C=180\\Then:\\\angle D=57.9\: \angle A=55.1\: \angle C=67\\\angle T=57.9\: \angle R=55.1\: \angle S=67$

What is the inverse of y= 3/2x -2

Mashcka [7]

Answer:

f^-1(x) = (2x + 4) / 3

Step-by-step explanation:

- switch 'y' with 'x'

x = 3/2y - 2

- solve for 'y'

x + 2 = 3/2y

- multiply each side by 2

y = (2x + 4) / 3

The cost , c(x), for a taxi ride was given by c(x) =2×+4.00, where x is the number of minutes. What does the slope mean for this

Readme [11.4K]

Hi,

c(x) is a linear function, if you graph it, you obtain a straight line.

The slope is the coefficient of x, therefore the slope is 2.

When the ride starts (x = 0), the start cost is 4 dollars (or whatever the currency is), then every minute spent on the moving taxi, as many as 2 dollars need to be paid to taxi driver.

I hope these help.

In emails to monthly readers of a newsletter 3% of the emails come back undelivered

MAXImum [283]

The prediction of the editor is not correct

Step-by-step explanation:

Step 1 :

Given,

Percentage of email that comes back undelivered = 3%

Number of email the editor sends out = 12181

Number of email predicted by the editor which is undelivered = 433

Step 2 :

To compute the actual number of emails undelivered we need to compute 3% of the emails that is actually sent.

= 3% of 12181 = 0.03 * 12181 = 365.43 which is 366 rounded to the closest integer.

Step 3:

Hence we can conclude that the prediction of the editor is not correct as only 366 undelivered notices are received back as against his prediction of 433 notices.

It takes 60 minutes to make 2000 copies on an old copy machine. The newer copier works with the old copier to create 2000 sheets

Cerrena [4.2K]

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

$60:2000::15:x$
