Answer:  13kg potatoes=9.36    2.5 of carrots=155p

Step-by-step explanation:

potatoes 5kg=3.6  carrots .5kg=31p

value of each kg of potatoes is...

\frac{3.6}{5} =.72  

so

13*.72=9.36

value of each kg of carrots is...

31x2=62

so (I assumed when you typed 21/2 it meant 2 1/2 or 2.5)

2.5x62=155

Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approxim
Firlakuza [10]

Answer:

Option C =8.4672\times10^{13}

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

                                                                   or = 5.88\times 10^{12} miles

In 14.4 lights year the distance is  =14.4\times (5.88\times10^{12})

                                                        =84.672\times10^{12}

                                                    or =8.4672\times10^{13}

Therefore, Option C is correct - =8.4672\times10^{13}

Answer:

1. Alt. Exterior angles (c)

2. Supplementary angles (e)

3.Alt. Interior angles (a)

4. Vertical angles (d)

5. Corresponding angles (b)

6. None (f)

7. Supplementary angles (e)

8. Alt. Interior angles (a)

9. M∠3 = 97°      M∠5 = 97°  

   M∠10 = 97°     M∠7 = 83°

   M∠9 = 83°      M∠16 = 97°

10. x = 5

11. x = 8

12. x = 20

Step-by-step explanation:

a.) 1-8

Alt. Exterior angles: Angles that are on the opposite sides of the transversal ( ex. 9∠16 and 13∠12)

Alt. Interior angles: Angles that are in the area between the parallel lines ( ex. 14 ∠11 and 10∠15)

Vertical angles: A pair of opposite angles formed by intersecting lines. ( ex. 12∠15 and 9∠14)

Corresponding angles: Angles that are in the same position relative to lines intersected by a transversal (ex. 9∠11 and 14∠16)

Supplementary angles: 2 angles that sum up to 180° ( ex. 9∠10, 11∠15, and 13∠14)

b.) 9

M∠2 is 97° and M∠3 are vertical angles so they both will have the same degrees (97°)

M∠2 and M∠10 are corresponding angles so they also will have the same degrees (97°)

Since you know M∠10 is 97° and a straight line is 180.

you would subtract 97 to 180 (180-97 = 83) so M∠9 is 83°

c.) 10-12

This is kind of like simple algebra

You would take M∠8 (4x+57) and M∠4 (77) and just put it into a problem ->

4x+57=77

    -57 = 77

4x=20

20/4 = 5

Help what do I do do i just write y-3x+5 or solve it ​
Rina8888 [55]

Answer:

y=-3x+5

Step-by-step explanation: Yes you have it correct. The question is asking for you to put it into an equation that fits the slope and y-intercept which is slope-intercept form. Additional note, when you have a problem like this and it doesn't say what type of equation form to put it in, put it in slope-intercept form for simplicity's sake.

Nick currently has 7,200 points in his fantasy baseball league, which is 20% points than Adam. How many points does Adam have?
Dovator [93]
Heya!!!


Answer to your question:

Let Adam's points be x.

Nick has points =7200=20%of x+x

20/100 *x + x=7200

x/5 +x=7200

6x/5=7200

x= 7200*5/6

x=6000

Adam has 6,000 points.

Hope it helps *_*
