Answer:

n = 18

Step-by-step explanation:

(2n) and (n + 18) are vertically opposite angles and are congruent, then

2n = n + 18 ( subtract n from both sides )

n = 18

Step-by-step explanation:

2250.6

Rachel's investment is worth $2251.60 after the first year.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

The investments earn 2.3% simple interest each year.

The interest earned in the first year is calculated as follows:

Interest = (2.3/100) x $2200

Apply the multiplication operation, and we get

Interest  = $51.60

So, Rachel's investment is worth $2200 + $51.60 = $2251.60 after the first year.

#SPJ6

Answer:

$165

Step-by-step explanation:

Cost of dinner = $132

Sales tax = 10% of dinner cost

Tip left = 15% of dinner cost

Amount of sales tax :

10% of $132

0.1 * $132 = $13.2

Amount of tip left :

15% * $132

0.15 * $132 = $19.8

Total cost of dinner :

Dinner cost + sales tax + tip

$132 + $13.2 + $19.8

= $165

Answer:

p=90

Step-by-step explanation:

Divide 2/3 on both sides. When you divide a fraction, you actually

multiply by its reciprocal, or opposite (3/2).

2/3p=60

*3/2 *3/2

p=180/2

p=90

Hope this helps and have a great day C:

Answer:

p = 1/90

Step-by-step explanation:

determine the defined range

2/3p = 60, p = 0

then multiply both sides of the equation by 3p

2 = 180p

swap both sides of the equation

180p = 2

then Divide both sides of the equation by 180

p = 1/90 p = 0

check the solution is it in the defined range

then you should get your answers

For -1:

y = x + 6

y = 5

( -1, 5)

For 0:

y = x + 6

y = 6

(0, 6)

For 2:

y = x + 6

y = 8

(2,8)

For 4:

y = x + 6

y = 10

Answer:

45 degree or 25%

Step-by-step explanation:

sum of angles of triangle= 180 so

[tex]180*\frac{30}{100}=54[/tex]-----> angle 1

(note: 30% is equal to [tex]\frac{30}{100}[/tex])

[tex]180*\frac{45}{100} =81[/tex]------> angle 2

lets add angle 1 and 2 together

54+81=135

now lets subtract it from 180 to get the remained angle

180-135=45 and if you want it in % so you just get 100%-(30%+45%)= 25%

Answer:

-14 is the answer

Step-by-step explanation:

Since 18+(-32) is the same as 18-32, the answer would be negative. When you subtract 32 by 18, you get 14. Moreover, you have to know which side is greater. If the integer is more on the left, meaning the negative side, then your sum of 18-32 is negative.

I know it's hard for people to understand me but I've tried my best to explain it to you. :)

Answer:

28/53

Step-by-step explanation:

Hey There!

So they want us to find the sine of angle S

well remember is sohcahtoa

S - sine

O - opposite

H - hypotenuse

meaning that

[tex]Sin=\frac{opposite}{hypotenuse}[/tex]

The opposite side of angle S is 28 and the hypotenuse is 53

so [tex]sinS=\frac{28}{53}[/tex]

Answer:

Total: $21.76

Step-by-step explanation:

Abby: 8.25

Maya: 10.50

Kayla: 6.85

Since Abby has a coupon for 15% we would multiply each meal by 15% to see how much money will be taken off by the coupon.

Abby: 8.25 x 0.15= 1.24

Maya: 10.50 x 0.15=1.58

Kayla: 6.85 x 0.15=1.02

Next subtract the amount of money taken off by the coupon by each meal.

Abby: 7.01

Maya: 8.92

Kayla: 5.83

Total: $21.76

answer:27

because -4 +4 = 0 x -3= -3 +27= 24

Answer:

x=1 and x=3

Step-by-step explanation:

When you factor it you get (x-1) and (x-3) then you subtract the 1 and 3 to the other side which is why the answer is positive.  

Answer:

x = 1, x = 3

Step-by-step explanation:

Equate the expression to zero, that is

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

the answer here is 13.2. hope this helps

4^3

you can write it like 4 × 4 × 4

you can also call it "Four to the Third power". or "Four cubed".

Answer:

# yellow = 20

# blue = 23

# red = 5

Step-by-step explanation:

let 'r' = # red marbles

let '4r' = # yellow marbles

let '3+4r' = # blue marbles

r + 4r + 3 + 4r = 48

9r + 3 = 48

9r = 45

r = 5

red = 5

yellow = 4(5) = 20

blue = 3+4(5) = 23

Answer:

y -3 = 2( x-1)

Step-by-step explanation:

Point slope form of a line is

y-y1 = m(x-x1)  where m is the slope and ( x1,y1) is a point on the line

y -3 = 2( x-1)

Answer:

3

Step-by-step explanation:

Lannister checks out 6 sets of book

Each set had the same number of books

She reads 7 books and has 11 more to go

Therefore the number of books in each set can be calculated as follows

= 11+7

= 18

18/6

= 3

Hence there are 3 books in each set
