The Perimeter Of This Shape Is 40cm Calculate The Value Of X

Answers

Answer 1

Answer:

x = 8

Step-by-step explanation:

The perimeter (P) is calculated as

P = 2(l + b) ← l is length and b is breadth

Here l = 12 and b = x , P = 40, then

2(12 + x) = 40 ( divide both sides by 2 )

12 + x = 20 ( subtract 12 from both sides )

x = 8

John waits on tables and is paid $8.00 an hour. In a 40-hour period, he earned $210.50 in tips. What were his total earnings?

a.) $530.50

b.) $1,684

c.) $520

Answers

Answer:

a.

Step-by-step explanation:

His total earning including tips of 210.50 dollars is a.) $530.50

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, John waits on tables and is paid $8.00 an hour. In a 40-hour period,

∴ His earning in those 40 hours is,

= (40×8) dollars.

= 320 dollars.

He also earned 210.50 dollars in tips.

∴ His total earnings is,

= (320 + 210.50) dollars.

= 530.50 dollars.

It takes 2 ounces of paint to completely cover all 6 sides of a rectangular prism box
which holds 15 cups of sugar. Double the dimensions of the box. Approximately how
much paint would the new box need? How much sugar would it hold?​

Answers

Answer:

120 cups of sugar

8 ounces of paint

Step-by-step explanation:

Given that :

To cover all sides of the rectangular prism with paint, that is the surface area.

The amount of sugar held by the prism is function of its volume.

Hence, doubling the dimension :

The surface area, in unit² is a obtained by

Initial paint required * 2^2

2 * 2² = 2 * 4 = 8 ounces of paint.

For sugar :

It has to do with volume, unit³

Initial * double³

15 * 2³

15 * (8) = 120 cups of sugar

Write the equation 3x+2y=8 in general form. SHOW YOUR WORK PLEASE

Answers

Answer:

3x+2y-8=0

Step-by-step explanation:

The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.

What is a numerical expression?

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We are given that  the equation 3x+2y=8.

The equation of straight line is written as y = mx + c

3x+2y=8.

2y = 8 - 3x

y = 8/2 - 3/2x

y = 4 - 3x/2

Hence, the general form is 3x + 2y - 8 = 0.

Fred is 4 times as old as Nathan and is also 27 years older than Nathan.
Let f be Fred's age and let n be Nathan's age.

Which system of equations represents this situation?

Answers

Answer:

f = 4n

f = n+27

Fred is 36 years old and Nathan is 9 years old.

n = 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Ooh I love these type of problems

Okay, here we go :

f = Fred and n = Nathan

  f = 4n

  f = n + 27

Above are the two equations (the words translated into algebra)

Now you can solve using substitution (any method works, but substitution is easiest for this problem)

4n = n + 27

3n = 27

n = 9

Since n = 9 substitute n into either equation

f = 4 * 9

f = 36

Fred is 36 and Nathan is 9
