I’m not sure what the answer is but the triangles are not congruent They are similar. The angles does look congruent but the sides or the triangle as a whole is just similar. So I think C should be tagged answer but angina I’m not sure but dilation does preserve angle measurement. So I guess C: yes at least two pairs of corresponding angles are congruent. is the closest. Hope this helps.

A painter can paint a building in 15 days and a coworker can do the same job in 10 days. If the first painter starts and 3 days

Sonja [21]

Answer: 7.8 days

<u>Step-by-step explanation:</u>

Painter can get the job done in 15 days so gets $\dfrac{1}{15}$ of the job done in 1 day.

Coworker can get the job done in 10 days so gets $\dfrac{1}{10}$ of the job done in 1 day.

Together, they get $\dfrac{1}{15}+\dfrac{1}{10}$ of the job done in 1 day.

Painter worked for 3 days so completed $\dfrac{1}{15}(3)=\dfrac{1}{5}$ of the job.

That leaves a remaining of $1-\dfrac{1}{5}=\dfrac{4}{5}$ of the job to be completed.

Let x represent the number of days it will take them to work together.

Painter + Coworker = Together

$\dfrac{1}{15}(x)\quad +\quad \dfrac{1}{10}(x)\quad =\quad \dfrac{4}{5}$

Multiply by 30 to eliminate the denominator:

$\dfrac{1}{15}(x)(30) +\ \dfrac{1}{10}(x)(30) = \dfrac{4}{5}(30)$

Simplify and solve for x:

2x + 3x = 24

5x = 24

$x=\dfrac{24}{5}$

x = 4.8

Remember that Painter worked 3 days alone in addition to the 4.8 days they worked together.

So the total time to paint the building is 3 + 4.8 = 7.8

How to solve In 14 + In x = 0

EastWind [94]

Answer:

x = 1/14

Step-by-step explanation:

You can work it as is by subtacting ln(14), then taking antilogs:

ln(x) = -ln(14)

x = 14^-1

x = 1/14

___

Or you can rewrite to a single log and then take antilogs:

ln(14x) = 0

14x = 1

x = 1/14 . . . . . divide by the coeffient of x
