S) This question is asking me to find the volume of the backpack.

O) Identify the facts: compartment one is 14x3x10, compartment two is 12x2x10, Julissa got a new backpack
Eliminate the unnecessary facts: Julissa got a new backpack
List the necessary facts: compartment one is 14x3x10, compartment two is 12x2x10

L) I chose Multiplication, I will multiply the measurements of compartment one, then multiply the measurements of compartment two and add them together to find the volume of the backpack.

V) I think the backpack will be at least 300 inches cubed.
(SOLVING PART)
Compartment one: 12 times 2 times 10 = 240
Compartment two: 14 times 3 times 10 = 420
420 + 240 = 660

E) Julissa’s backpack is 660 inches cubed.

I hope this helps

HELP PLEASE!!!

Answer:

The answer is 18 cm

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • A force of 100 newtons stretches a spring 5 cm
<h3><u>To </u><u>Find</u>;</h3>
  • If a force of 360 newtons then how much a spring will be stretches

Now, We need to write a proportion

Here,

Force₁ = 100 N

Length₁ = 5 cm

Force₂ = 360 N

Length₂ = x cm

Now,

Force₁ ÷ Length₁ = Force₂ ÷ Length₂

100/5 = 360/x

100x = 360 × 5

100x/100 = 360 × 5/100

x = 18 cm

Thus, If a force of 360 newtons then 18 cm a spring will be stretches.
