Equation: 1.15 c = 40

Solution: $34.78

Step-by-step explanation:

The given is:

  • Sam bought a computer game that costs 15% more than a printer cartridge
  • c is the cost in dollars, of the printer cartridge

We need to write an equation that can be used to find c, and then

find the value of c

∵ The cost of the printer cartage = $c

∵ The computer game costs 15% more than a printer cartridge

- That means add the cost of the cartage by 15% of it to find the

   cost of the computer game

∴ The cost of the computer game = c + 15% × c

∵ 15% = 15 ÷ 100 = 0.15

∴ The cost of the computer game = c + 0.15 c

- The two terms of c (1 + 0.15)

∴ The cost of the computer game = $1.15 c

∵ The cost of the computer game = $40

- Equate the two expressions of the cost of the game

∴ 1.15 c = 40

The equation that can be used to find c is 1.15 c = 40

Solve the equation to find c

∵ 1.15 c = 40

- Divide both sides by 1.15

∴ c = $34.78

The cost of the printer cartridge is $34.78

Equation: 1.15 c = 40

Solution: $34.78

One of the formulas for calculating the correct dosage for a child is as follows: C= a/((a+12)) ∙ 180 C = child’s dosage in mill
bogdanovich [222]
So you already have the formula for calculating the dosage for child with: C = a/(a+12)x 180 ml Not sure why you have double brackets

variables are: a = child's age, so everywhere you have an "a" replace it with the age of child.

Example: 5 year old child

C = 5/(5+12)*180= 5/(17)*180 = 5/3060 = .0016 ml or milligrams

PLEASE HELP IM ON A TIME LIMIT :(

Answer:

hey hope this helps

<h3 /><h3>Comparing sides AB and DE </h3>

AB =

\sqrt{ {1}^{2} +  {1}^{2}  }

=  \sqrt{2}

DE

= \sqrt{ {(3 - 5)}^{2} +  {(1 + 1}^{2}  }  \\   = \sqrt{ {( - 2)}^{2}  +  {(2)}^{2} }  \\    = \sqrt{4 + 4}  \\  =  \sqrt{8}  \\   = 2 \sqrt{2}

So DE = 2 × AB

and since the new triangle formed is similar to the original one, their side ratio will be same for all sides.

<u>scale factor</u> = AB/DE

= 2

It's been reflected across the Y-axis

<em>moved thru the translation of 3 units towards the right of positive x- axis </em>

for this let's compare the location of points B and D

For both the y coordinate is same while the x coordinate of B is 0 and that of D is 3

so the triangle has been shifted by 3 units across the positive x axis
