[tex]\large\underline{\textsf{According to PEMDAS;}}[/tex]

[tex]\textsf{We should first remove the exponent by multiplying the values in the parentheses}[/tex]

[tex]\tt (x+1)^{4}=(x+1)\times(x+1)\times(x+1)\times(x+1)[/tex]

[tex]\textsf{Evaluate the product, then multiply that product by 16.}[/tex]

Answer:

5750 = 1500 + 250x

17 months

Step-by-step explanation:

Let x represent the number of months it would take to pay for the car

the total cost of the car is a function of the down payment and the monthly payments

$5750 = $1500 + 250x

to solve for x, collect like terms

5750 - 1500 = 250x

4250 = 250x

Divide both sides by 250 to find x

x = 17 months

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:

-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:

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:

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

Answer:

8.20

Step-by-step explanation:

4x0.75=3

3+4=7

0.6=60%

60% of 0.75= 0.45

0.75+0.45=1.20

7+1.20=8.20

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

Answer:

Division

Step-by-step explanation:

here's your process

=>. it is your equation 17b = 54

=> now divide 17 on both side

=> then we get 17b/17 = 54/17

=> hence , we get b = 54/17

=>now b is isolated by the method of division

Answer:

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.

Answer:

Rounding to the Nearest Integer

The most common type of rounding is to round to the nearest integer. The rule for rounding is simple: look at the digits in the tenth's place (the first digit to the right of the decimal point).

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

Answer:

=13/3

Step-by-step explanation:

1. Distribute

3+2(4−6)=8+1

3+8−12=8+1

2. Combine like terms

3+8−12=8+1

11−12=8+1

3. Add 12 to both sides of the equation

11−12=8+1

11−12+12=8+1+12

4. Simplify

11=8+13

5. Subtract 8x from both sides of the equation

11=8+13

11−8=8+13−8

6. Simplify

3=13

7. Divide both sides of the equation by the same term

3=13

3x÷3=13÷3

8. Simplify

If you cancel terms that are in both the numerator and denominator you will get:

=13/3

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:

Perimeter: 32

X = 5

Step-by-step explanation:

If you draw a line to make the triangle the longer leg is equal to 4 then the shorter leg is 3 since your subtracting 13 - 10 to get 3 for the shorter leg. you use Pythagorean theorem that would equal 3^2 + 4^2 = 25 if you take the square root of 25 its 5. So now you know x = 5. Then add all the sides together to get the perimeter.

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
