Answer:

Part A:

In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.

Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom

Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.    

Step-by-step explanation:

postnew [5]

Answer:

$1.75  cost of the funnel cake and $4.25 cost of the ice cream cone.

Step-by-step explanation:

x = cost of the ice cone cone

y = cost of the funnel cake

3x + 4y = 19.75      multiply (-2)       ⇔     -6x - 8y = -39.50

5x + 8y = 35.25    do not change   ⇔  +<u>  5x + 8y = 35.25</u>

                                                                     -x  =  -4.25

                                                                      x = 4.25  cost of the ice cream cone

Substitute into the second equation x = 4.25 and solve  for y

5(4.25) + 8y = 35.25

21.25 + 8y = 35.25

  8y = 14

y = 1.75    cost of the funnel cake

Ming says that 0.24 &gt; 1/4 because 0.24 = 2/4. Which best explains Ming's error?
Iteru [2.4K]
Because 0.24 = 24/100 and 1/4= 25/100 and 0.24 = 24/100 and 2/4/ 50/100=2
and so she missed calcuated and so its wrong.

the correct answer is 0.24<2/4 then 0.24=/2/4 

wrong symbol

Answer:

use some propoerties of exponnets

(x^m)/(x^n)=x^(m-n)

so

convert every body to scientific notation

(number less than 10 but equal to or greater than 1) times (10^x)

baby=26,000,000,000

how many decila places to move to left to make less than 10 but equal to or great than 1

10

there for it can be writtten as

2.6*10^10

how many times bigger is adult than baby

baby times x=adult

divide adult by baby with the numbers

x==

times  =

1.9 times 10^3

answer is 1.9*10^3
