Nayeli goes out to lunch. The bill, before tax and tip, was $18.40. A sales tax of 9% was added on. Nayeli tipped 12% on the amount after the sales tax was added. How much was the sales tax? Round to the nearest cent.

Answer:

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

     -3    +    -5    =    -8

     -1    +    -15    =    -16

     1    +    15    =    16

     3    +    5    =    8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  3  and  5

                    x2 + 3x + 5x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+3)

             Add up the last 2 terms, pulling out common factors :

                   5 • (x+3)

Step-5 : Add up the four terms of step 4 :

                   (x+5)  •  (x+3)

            Which is the desired factorization

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

tan 19° = 0.3443

Step-by-step explanation:

Value Of Trigonometric Functions

The value of the tangent of 19° cannot be expressed in exact form, that it, as a function of radicals or known constants as pi.

We need to use a calculator, computer, or similar technology to find the required value. We use a scientific calculator to get:

tan 19° = 0.3443

Step-by-step explanation:

x² + 7x + 12 = 0

x² + 3x + 4x + 12 = 0

x(x + 3) + 4(x + 3) = 0

(x + 4)(x + 3) = 0

Answer:

1380 children and 820 adults went to the zoo that day

Step-by-step explanation:

System of Equations

Define the following variables

x = number of children that went to the zoo

y = number of adults that went to the zoo

On a certain day,  2000 people went to the zoo, thus:

x + y = 2000

Solving for x:

x = 2000 - y        [1]

The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:

1.50x + 4y = 5050       [2]

Substituting x from [1]:

1.50(2000 - y) + 4y = 5050

Operating:

3000 - 1.50y + 4y = 5050

3000 + 2.5y = 5050

Subtracting 3000

2.5y = 5050 - 3000 = 2050

Dividing by 2.5

y = 820

From [1]

x = 2200 - 820 = 1380

1380 children and 820 adults went to the zoo that day

Step-by-step explanation:

SASS THATS HOW YOU FIGURE IT OUT LOOK IT UP

Answer: y=1/2x+3

m is the slope in the equation y=mx+b. you find b by plugging in (8,7) into the equation y=1/2x+b. Plug in 7 for y and 8 for x. The equation will look like 7=1/2(8)+b. solve for b. b should equal 3.

so your answer is y=1/2x+3

x is always +3 ahead (30-27=3)

and y is always trailing behind x by -3

Answer:

y = x - 3

Step-by-step explanation:

You are given an x and a y and need to find the difference.

Set up a formula using one of the given x and y pairs and solve.

y = x - u  plug in an x and y and solve for the unknown(u)

27 = 30 - u

-3 = -u

u = 3

Now plug the unknown into the original equation

y = x - 3

The decimal rounded to the nearest hundredth is 2.16

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.

Given:

41/19

Now, dividing the fraction

41/19

= 2.1578

Now, rounding off to nearest hundredth focus on thousandth place value whether it is greater than 5 or not.

Hence, the decimal rounded to the nearest hundredth is 2.16

41/19

= 2.1578

2 = one place value

1 = tenth place value

5 = hundredth place value

7 = thousandth place value

8 = ten thousandth place value.

The value of 41/19 as a decimal rounded to the nearest hundredth is 2.16.

The place value of a number is given as:

Example:

1234.567

1 = thousand place value

2 = hundred place value

3 = tens place value

4 = ones place value

5 = tenths place value

6 = hundredths place value

7 = thousandths place value

We have,

41/19

2.1578

5 is in the hundredth place value.

Rounding to the nearest hundredth-place value.

Since the thousandth place value is greater than 4.

We have,

2.16
