Write 15/45 as unit rate

HELPPPP What is MB 48 96 110 55

Lady_Fox [76]

Minor Arc AC = 110 degrees (given)
As indicated in the hints,
OA=OC => OAC=OCA=(180-110)/2 = 35
Similarly,
OAB=OBA=(48-35)=13
=>
OBC=OCB=(180-35-35-13-13)/2=(180-96)/2=84/2=42
=>
Angle B = 13+42 = 55 degrees

Check:
55+55+35+35+13+13 = 180 degrees (angles of a triangle) ok.

A square piece of paper is folded in half vertically. The resulting figure has a perimeter of 21 in. What is the number of units

Rudiy27

Perimeter is adding all 4 sides together.

To find the length and width divide total perimeter by 2:

21 / 2 = 10.5

We now know the length of 1 side and the width of 1 side need to equal 10.5.

Since the original piece was a square we also know the width needs to equal 1/2 of the length.

So we have L + 1/2L = 10.5

Add the common terms 1 L + 1/2 L = 1 and 1/2 L

To Find L divide 10.5 by 1-1/2, which equals 7

To find the width subtract 7 from 10.5, which equals 3.5

So the paper is now 3.5 inches by 7 inches.

Answer:

Part 1)

Part 2)

Part 3)

Part 4)

Part 5)

Part 6)

Step-by-step explanation:

Part 1)

Multiply by -1 both sides

The solution is the interval -------> [-1.817,∞)

The solution in the attached figure N 1

Part 2)

rewrite

Multiply by -1 both sides

The solution is the interval--------> (0.09,∞)

The solution in the attached figure N 2

Part 3)

combine like terms

Adds 8 both sides

The solution is the interval--------> (-∞,6]

The solution in the attached figure N 3

Part 4)

Adds 5 both sides

Multiply by -1 both sides

Divide by 2 both sides

The solution is the interval--------> (-7,∞)

The solution in the attached figure N 4

Part 5)

applying distributive property left side

Subtract 14 both sides

Divide by 7 both sides

The solution is the interval--------> (-∞,-13)

The solution in the attached figure N 5

Part 6)

applying distributive property left side

Adds 117 both sides

Divide by -1 both sides

Divide by 13 both sides

Do I add multiply, add, subtract ? I need help!

bazaltina [42]

Answer:

x=35

Step-by-step explanation:

you are going to want to subtract. the best thing about triangle angles is that they all add to equal 180º no matter what. so what you can do is subtract the given angles from 180. so 180-80-65. which gives us 35.

Hope this helps!
