Answer:

46) 135°

47) 225°

48) 270°

49) $\frac{3}{8}$ (3/8)

50) $\frac{3}{4}$ (3/4)

Step-by-step explanation:

{the following is if you do not understand my drawing}

There are 4 segments that we can imagine - north, south, east, and west

We can imagine that these lines all meet a circle

There are 360 degrees to a circle. So, if we divide that by 4, we know that each segment is 90 degrees.

(Also, you can probably see that the angles are right angles, or you know that straight lines are 180 degrees, you probably know this information intuitively)

This means that each smaller segment, two in both of our four segments, is 45 degrees.

These 8 sections are each 1/8 of the total circle.

Reaching for something in the distance
So close you can almost taste it
Release your inhibitions
Feel the rain on your skin
No one else can feel it for you
Only you can let it in
No one else, no one else
Can speak the words on your lips
Drench yourself in words unspoken
Live your life with arms wide open
Today is where your book begins
The rest is still unwritten

The glasers had $317 in their checking account. They wrote checks for $74, $132, and $48. What is their checking account balance

Masja [62]

To solve this, you would first add the amount of the 3 checks they wrote together. So, 74+132+48=254. Then, we know that they had $317 in their checking account. Now, you would take the amount they had in their account (317), and subtract it by the total of the 3 checks they wrote (254).

The checking account balance is 317-254=63, so $63 is their checking account balance.

I really hope this helps you.

Jim and Abby each bought burgers and fries from the concession stand at the fair. Jim bought 3 burgers and 2 orders of fries for

makkiz [27]

Answer:

The price of each burger is $4

The price of each order of fries is $2.5

Step-by-step explanation:

* Lets explain how to change the story problem to equations

- Jim bought 3 burgers and 2 orders of fries for $17

- Abby bought 2 burgers and 4 orders of fries for $18

- Assume that the price of one burger is x and one order of fries is y

* Lets write two equations represents Jim and Abby orders

∵ Jim bought 3 burgers and 2 orders of fries for $17

∴ 3x + 2y = 17 ⇒ (1)

∵ Abby bought 2 burgers and 4 orders of fries for $18

∴ 2x + 4y = 18 ⇒ (2)

* Lets solve the two equations by the elimination method

- Multiply equation(1) by -2 to eliminate y

∵ -2(3x) + -2(2y) = -2(17)

∴ -6x + -4y = -34 ⇒ (3)

- Add equations (2) and (3)

∴ -4x + 0 = -16

∴ -4x = -16

- Divide both sides by -4

∴ x = 4

- Substitute the value of x in equations (1) or (2) to find y

∵ 3x + 2y = 17

∴ 3(4) + 2y = 17

∴ 12 + 2y = 17

- Subtract 12 from both sides

∴ 2y = 5

- Divide the both sides by 2

∴ y = 2.5

∵ x represent the price of each burger

∴ The price of each burger is $4

∵ y represents the price

of an order of fries

∴ The price of each order of fries is $2.5
