Answer:

I assume you're solving for x, so the answer is 10

Step-by-step explanation:

First you isolate the x, so you need to subtract one from both sides, which results in the equation 2.5x = 25, and then you divide 25 by 2.5, which gives you x = 10

Answer-

$\boxed{\boxed{\dfrac{\widehat{BC}}{\widehat{DE}}=\dfrac{3}{4}}}$

Solution-

We know that arc length is the product of radius and central angle in radian.

i.e $\text{Arc length}=\text{Radius}\times \text{Central angle}$

Here,

$\theta_{BC}=1.18\ rad,\ \theta_{DE}=2.36\ rad\\\\AD=\dfrac{2}{3}AB\Rightarrow AB=\dfrac{3}{2}AD$

So,

$\dfrac{\widehat{BC}}{\widehat{DE}}=\dfrac{AB\times 1.18}{AD\times 2.36}$

$=\dfrac{\frac{3}{2}AD\times 1.18}{AD\times 2.36}$

$=\dfrac{3\times 1}{2\times 2}$

$=\dfrac{3}{4}$

You discovered 1000 grams of an unknown element called Coolium 23 that has a half life 23 days. How long will it take for you to

Trava [24]

Answer:

13.8 days

Step-by-step explanation:

In this case we can solve it by means of a rule of three, knowing the amount of life for 1000 grams, it must be proportional for 600 grams, like this:

grams days

1000 23

600 x

x = 600 * 23/1000

x = 13.8

which means that for the 600 grams it would be an average life of 13.8 days.

Zeus Industries bought a computer for $2593. It is expected to depreciate at a rate of 30% per year. What will the value of the

Natalija [7]

First year:
.3 x 2593 = 777.9

$2593 - $777.90 = $1815.10

Second year:
.3 x 1815.10 = 544.53

$1815.10 - $544.53 = $1270.57

Third year:
.3 x 1270.57 = 381.171

$1270.57 - $381.171 = $889.39900

$889.39900 rounded to the nearest hundredth is $889.40
