What values of x solve x 2 - 4x + 3

Answers

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

Henry's dinner bill is $132 the sales tax is 10% humidity of 15% how much will I pay in taxes how much does he pay in tip what is his total bill

Answers

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

Lannister checks out 6 set of books from the library each set has the same number of books she reads 7 of the books and she has 11 books left to read how many books are in each sets

Answers

Answer:

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

Find the value of each variable.
a=
b=
c=
d=

Answers

Answer:

✔ 6

✔ 3

✔ 64

Step-by-step explanation:

We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3. We can use trigonometric functions to find the answer.

What are trigonometric functions?

Trigonometric functions are the ratios existing between the sides of a right-angled triangle. These ratios are constant for every right-angled triangle.

The sine of any angle is given by opposite side/hypotenuse.

The cosine of any angle is given by the adjacent side/hypotenuse.

Steps:Step 1 of 4:

We can find the value of a using sin 45:

sin 45 = 1/√2

⇒ a/17√2 = 1/√2

⇒ a/17 = 1

⇒ a = 17

Step 2 of 4:

We can find the value of c using cos 45:

cos 45 = 1/√2

⇒ c/17√2 = 1/√2

⇒ c/17 = 1

⇒ c = 17

Step 3 of 4:

We can find the value of b using sin 30:

sin 30 = 1/2

⇒ a/b = 1/2

Substitute the value of a:

17/b = 1/2

⇒ b = 34

Step 4 of 4:

Now we can use cos 30 to find the value of d:

cos 30 = √3/2

⇒ d/b = √3/2

Substitute the value of b:

d/34 = √3/2

⇒ d = 34*√3/2

⇒ d = 17√3

Therefore, We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3.

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

Three friends go out to dinner. Abby gets a hamburger that costs $8.25,
Maya gets pasta that costs $10.50, and Kayla gets chicken fingers that
cost $6.85. Abby has a coupon for 15% off that she agrees to let
everyone use. Rounded to the nearest dollar, what is the total cost of
the meal, including the discount?

Answers

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

Rachels company invest 2200 for her each year she works for the company. The investments earns 2.3% simple interest each year. Rachel has worked for this company for one year how much is her investment worth?

Answers

Answer:

Step-by-step explanation:

2250.6

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

What is the simple interest?

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.

Zair has 48 marbles in his pocket. He has 3 more blues than the
yellow ones, and 4 times as many yellows as the red ones. How
many of each colored marble is there?

Answers

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
