Astronomers often measure large distances using astronomical units (AU) where 1 AU is the average distance from Earth to the Sun. In the image, represents the distance from a star to the Sun. Using a technique called “stellar parallax,” astronomers determined θ is 0.00001389 degrees.



How far away is the star from the Sun in astronomical units?Show your reasoning.

Answer:

17 to 24

25 to 32

Step-by-step explanation:

8-1=7

16-9=7

therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32

Answer: 17 to 24 then 25 and 32

Answer:

Tally marks

Step-by-step explanation:

It is most likely tally marks because all of the other options are more recent than option b the Greek and Latin letters are dated to be closer to the modern times than the cavemen were.

The answer is.

y = 2, x = -4

Answer:

x=-4

Step-by-step explanation:

First substitute y=3x+14

2x-3(3x+14)=-14

Distribute:

2x-9x-42=-14

Add or subtract like terms

-7x-42=-14

-7x=28

Finally divide both sides by -7

-7x/-7=x

28/-7=(-4)

x=-4

Answer:

x=2

Step-by-step explanation:

x6−7=5

x6=7+5

x6=12|:6

x=2

Answer:

Step-by-step explanation:

7 hr/3 pumps

So first we want to find the unit rate which would be...

5.25 hr/1 pump

Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...

5.25*2=10.5

So our answer is 10.5 hr/ 2 pumps

Answer:

$17.55

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 390 × 0.03 × 1.5 = 17.55

I = $ 17.55

The simple interest accumulated

on a principal of $ 390.00

at a rate of 3% per year

for 1.5 years is $ 17.55.

Answer:

Step-by-step explanation:

common factor of 2a² and 10ab= 2a

Answer:

Step-by-step explanation:

No this is not proportional , because the ratio of y/x for each one is not same ,

As for 1st one ,

y/x =4/2 =2

for 2nd one ,

y/x=16/4 = 4 and so on

so they re not equal that's why they are not proportional

Answer:

18a^7

Step-by-step explanation:

Answer:

the y-values for the x-values, starting with -3, are:

-5, -4, -3, -2, -1, 0, 1

Step-by-step explanation:

for each, plug the x-value into the equation y = x - 2 and get the result

example, when x = -3 then y = (-3 - 2) which is -5

Answer:

x = 40/21

Step-by-step explanation:

This should be the right answer...

Answer:

Answer is 4/5

Step-by-step explanation:

=3/5(7x+10)=14

=21x/5+53/5=14

=21x/5=14-53/5

=21x/5=3.4

=x=3.4×5/21

=x=0.8 or 8/10=4/5

Answer:C

Step-by-step explanation:

Answer:

f(-9) = 243

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 4x² + 7x - 18

f(-9) is x = -9

Step 2: Evaluate

As, we have f(x) = 4x² + 7x - 18, so to find f(- 9) substitute value of x as (-9).

[tex] \tt : \implies f(-9) = 4(-9)² + 7(-9) - 18[/tex]

[tex] \tt : \implies f(-9) = 4 \times 81 + (-63) - 18[/tex]

[tex] \tt : \implies f(-9) = 324 - 63 - 18[/tex]

[tex] \tt : \implies f(-9) = 324 - 81[/tex]

[tex] \tt : \implies f(-9) = 243[/tex]

[tex] \Large \underline{\boxed{\bf{f(-9) = 243}}}[/tex]

Hence, value of f(- 9) = 243.

Answer: They had 24 items for the sale.

Step-by-step explanation:

Given: In baking sale,

18 different people made 2 dozen items for the sale.

We know that,

1 dozen = 12 items

2 dozens = 2 x 12 items

i.e. 2 dozens = 24 items

Therefore, they will have 24 items for sales if they made 2 dozens items.

Hence, they had 24 items for the sale.

Answer:

24 items for the sale.

Theres a "add answer" just click on that and u will be able to add

Step-by-step explanation:

[tex]7x + 12 = 9x - 6[/tex]

[tex]7x + 12 - 7x = 9x - 6 - 7x[/tex]

[tex]12 = 2x - 6[/tex]

[tex]12 - 6 = 2x -6 - 6[/tex]

[tex]6 = 2x - 12[/tex]

[tex]6 + 12 = 2x[/tex]

[tex]18 = 2x[/tex]

[tex]18 \div 2 = x[/tex]

[tex]9 = \bold{ x}[/tex]

In pythagoras, c is the hypotenuse. That is AC. Where a is AB and b is BC.

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {(6 x + 5)}^{2} = {(7x + 12)}^{2} + {BC}^{2} [/tex]

[tex] {((6 \times 9) + 5)}^{2} = {((7 \times 9)}^{2} + 12)^{2} +{BC}^{2} [/tex]

[tex] {(54 + 5)}^{2} = {(63 + 12)}^{2} + {BC}^{2} [/tex]

[tex] {59}^{2} = {75}^{2} + {BC}^{2} [/tex]

[tex]3481 = 5625 + {BC}^{2} [/tex]

[tex]3481 - 5625 = {BC}^{2} [/tex]

[tex] - 2144 = {BC}^{2} [/tex]

[tex] \sqrt{ - 2144} = BC[/tex]
