Answer:

so to find the weight of this years model we do this

645*0.8=516

so the answer is 516

Answer: (12) ∠1 = 20° (13) ∠2 = 50° (14) ∠3 = 15° (15) UV = 80° (16) AB = 40° (17) ABC <em>or</em> 180° - CD (18) BC - 140° (19) ABC = 150°

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

12) $\frac{1}{2}$ (UV - ST) = ∠1

$\frac{1}{2}$ (80 - 40) = ∠1

$\frac{1}{2}$ (40) = ∠1

20 = ∠1

13) $\frac{1}{2}$ (UV + ST) = ∠2

$\frac{1}{2}$ (70 + 30) = ∠2

$\frac{1}{2}$ (100) = ∠2

50 = ∠2

14) $\frac{1}{2}$ (VB - BS) = ∠3

$\frac{1}{2}$ (60 - 30) = ∠3

$\frac{1}{2}$ (30) = ∠3

15 = ∠3

15) $\frac{1}{2}$ (UV - ST) = ∠1

$\frac{1}{2}$ (UV - 20) = 30

UV - 20 = 60

UV = 80

16) ∠1 = arc AB

∠1 = 40

arc AB = 40

17) arc AB + arc BC = arc AC

= 180 = arc CD

18) ∠1 + ∠2 + ∠3 = 180

20 + ∠2 + 20 = 180

∠2 + 40 = 180

∠2 = 140

19) ∠1 + ∠ 2 = arc ABC

∠1 + ∠2 + ∠3 = 180

arc ABC + 30 = 180

arc ABC = 150

What is the complete factorization of the polynomial below?<br> x3 + x2 + 9x+9

PIT_PIT [208]

Answer:

(x+1)(x-3i) (x+3i)

Step-by-step explanation:

x^3 + x^2 + 9x+9

We will use factor by grouping

Factor out x^2 from the first group and 9 from the second group

x^3 + x^2 + 9x+9

x^2( x+1) + 9(x+1)

Factor out (x+1)

(x+1) ((x^2+9)

Now factor x^2+9

x^2 -(3i)^2 = (x-3i) (x+3i)

Replacing this

(x+1)(x-3i) (x+3i)

Earth revolves around the Sun in 365 days, but the planet Mercury does so in only 88 days. Compared to Earth, how many more comp

Elena L [17]

Answer:

In a 1000 days Mercury will make 8.624 more revolutions than Earth!

Step-by-step explanation:

<u>Earth</u> takes 365 days to make a complete revolution.

we can say that the rotational speed of Earth is $\dfrac{1}{365}\frac{\text{rev}}{\text{day}}$

so, in a 1000 days how many revolutions will Earth have made?

$\dfrac{1}{365}\frac{\text{rev}}{\text{day}}\times(1000\,\text{day})$

see that the 'day's cancel out. Simply multiply the two numbers!

$2.739\text{rev}$

<u>Next, do the same for Mercury</u>

we can say that the rotational speed of Mercury is $\dfrac{1}{88}\frac{\text{rev}}{\text{day}}$

as it completes 1 revolution in 88 days.

so, in a 1000 days how many revolutions will Mercury have made?

$\dfrac{1}{88}\frac{\text{rev}}{\text{day}}\times(1000\,\text{day})$

multiplying by 1/88 by 1000 yields:

$11.363\text{rev}$

The Question is how many MORE complete revolutions will Mercury make in 1000 days?

We need to subtract the revolutions of Mercury with Earth to find how far ahead is Mercury from Earth

$11.363\text{rev} - 2.739\text{rev}$

$8.624\text{rev}$

In a 1000 days Mercury will make 8.624 more revolutions than Earth!
