Ann can build a model car in 5 hours, while Sam can build the same model in 15 hours. How many hours would it take for them to b

Yuri [45]

3 hours and 45 minutes

The equation can be solves by adding their two efforts together in a ration equation. See below.

5/x + 15/x = 1

Then give them common denominators and add and solve.

Stiind ca triunghiurile sunt asemenea si c= 5 calculati lungimea laturilor indicate

slava [35]

Answer:

$a=8\\b=10\\c=5$

Step-by-step explanation:

In the given image, you can observe we have two right triangles.

Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.

If the triangles are similar, we can define the following proportion between sides.

$\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8$

Now we use the Pythagorean's Theorem to find each hypothenuse.

$c^{2} =4^{2} +3^{2}\\ c=\sqrt{16+9}=\sqrt{25} \\ c=5$

$b^{2} =8^{2} +6^{2}\\ b=\sqrt{64+36}=\sqrt{100}\\ b=10$

Therefore, the missing sides are

$a=8\\b=10\\c=5$

Which of the following functions shown in the table below is not an exponential function?

kramer

Answer:

B. f(x)

D. h(x)

Step-by-step explanation:

An exponential function will have a common ratio.

We check and see if the consecutive terms has a common ratio.

For f(x),

$\frac{5}{2} \ne \frac{10}{5}$

This is not an exponential sequence.

For g(x), we have:

$\frac{2}{1} = \frac{4}{2} = \frac{8}{4} = 2$

For h(x),

$\frac{1.25}{1} \ne \frac{1.5}{1.25}$

This is not an exponential sequence

For k(x),

$\frac{16}{64} = \frac{4}{16} = \frac{1}{4} = \frac{0.25}{1}$
