What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of food = $137 . 61

Tip = 18%

tax = 6.5%

Now, price after giving tip

=137.61 x 0.18

= 24.7698

and, after tax

=137.61 x 0.065

=8.94465

Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

p/ 1 6/7=−4.4 help please!!!!!!!

Answers

Answer:

Sorry, I can't type well.

The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

p / [1 ⁶/₇] = - 4.4

Convert the mixed fraction number into a decimal number. Then we have

1 ⁶/₇ = 1 + ⁶/₇

1 ⁶/₇ = 1 + 0.857

1 ⁶/₇ = 1.857

Then the equation is rewritten as,

p / 1.857 = - 4.4

Simplify the equation, then we have

p = - 4.4 x 1.857

p = - 8.17

The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.

2.54 cm = 1 inch
10 mm = 1 cm

Answers

I don’t know the answer but you would have to first convert the 2.625 inches into cm and then convert the cm to mm to get your answer
Convert 2.625 inches into centimeters and then convert it again but in millimeters you will get 66.7mm
No need to find diameter because it was given there in inches just convert

2.625 inches = 6.67 centimeters
6.67cm = 66.7mm

The sales tax is: $_________

The total cost is: $_________

Is it enough money?

Sales tax: 1.98465 which in this case is $1.98 (take note that you can round and it would be $2)

The total cost: $21.63 so no, Courtney cant buy the stuffed animal :(

Step-by-step explanation:

You can find the sales tax by dividing 10.1 by 100 to get 1.984...then rounding that number to get $1.98 since we are working with money in this problem then we have to find the total cost by adding our sales tax ($1.98) to our original cost ($19.65) to get our FINAL answer of $21.63

Solve for m.

Write your answer as a fraction or as a whole or mixed number.

Answers

Answer:

5 7/8

Step-by-step explanation:

Do the inverse operation.

5 + 7/8 = 5 7/8

Or, do this instead!

Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!
