Bailey wanted a new pair of shoes. She put the $142 cost on her
credit card. Because Bailey has been irresponsible with her credit,
the credit card company charges her 22% annual interest. Figure
Bailey's balance after 180 days, assuming she made no payments.

Answers

Answer:

Bailey's balance after 180 days is $ 157.39.

Step-by-step explanation:

Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:

365 = 100

180 = X

180 x 100/365 = X

18,000 / 365 = X

49.31 = X

22 x 0.4931 = 10.84

142 x 1.1084 = X

157.39 = X

Thus, Bailey's balance after 180 days is $ 157.39.

3/4x2/1=3/2=1 1/2

Answer:

3/2 or 1 1/2

Step-by-step explanation:

Hi,

3/4 divided by 1/2 is the same thing as 3/4 x 2/1. (when dividing fractions, flip the second fraction) When you do this, you simply multiply straight across. So...

3/4 x 2/1 = 6/4

Simplify...

3/2 (both 6 and 4 can be divided by 2)

3/2 = 1 1/2

The difference between twice a number and 16 is 30. Which math statement is an equation that represents this relationship?

A) 30 – 16 = x
B) x – 16 = 30
C) 2x + 16 = 30
D) 2x – 16 = 30
E) 2x + 30 = 16

Answers

Answer:

D

Step-by-step explanation:

Answer:

D is the correct answer :)

Step-by-step explanation:

Hi,

Twice a number is 2x (x because we don't know what that number is) The word "difference" suggests we're subtracting. So, 2x - 16 = 30 is correct.

I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.

Last 3 questions thank you so much

Answers

Answer:

Step-by-step explanation:

1)  

we are given ∠17  and the Adj = 200 meters they want to know the Opp

so use  TOA

Tan(17) = Opp / 200

200*Tan(17) = Opp

61.146 = Opp

the mast stands 61.1 meters tall   ( rounded to nearest 10th )

2)

now we know the opp = 40 meters and the angle is 35° and Adj = x

Use TOA again, but w/ the different knowns

Tan(35) = 40 / Adj

Adj = 40 / Tan(35)

57.1259 = Adj

so the boat is 57.1 meters from the cliff  ( rounded to nearest 10th)

3)

we are given two triangles now and are told to find the difference between them to find the distance between the buoys

Opp = 70

∠A = 60

∠B = 40

we want to find the Adj for each so use TOA

for A , then

Tan(60)= 70/a

a = 70 / Tan(60)

a = 40.4145

for B, then

Tan(40) = 70 /b

b = 70 / Tan(40)

b = 83.4227

so subtract  a  from b

83.4227 - 40.4145 = 43.008

so from buoy A to buoy B is 43.0 meters ( rounded to nearest 10th )

Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

[tex]\frac{3x}{3} = \frac{60}{3}[/tex]

x = 20

The length of a rectangle is 3 less than 4 times the width. The perimeter is 34. Find the length and width.

Answers

Length is 13

Width is 4

Step-by-step explanation:

Length: 4w-3

Width: w

2L + 2w= P

2(4w - 3) + 2(w)= 34

8w - 6 + 2w= 34

10w - 6= 34

10w = 40

w= 4

Length: 4w-3

4(4) - 3= 13

Width= w
