Answer:
2.5
Step-by-step explanation:
you can use pythag theorem and divide c by two:
-3^2+4^2=c^2
9+16= 25
c=5
however, 5/2=2.5
Step-by-step explanation:
-8 ( - 5 + 13) + 2 : 1 x 2
-8 ( 8) + 2 : 2
-64 + 1
-63
Step-by-step explanation:
Solutions, colloids and suspensions are the three main classifications of a mixture based on sizes of the particles.
- A solution is a homogeneous mixture of solutes and solvents.
- Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
- Colloids are homogeneous mixtures of two phases.
Solutions have the following characteristics:
- The size of particles is small
- The particles do not settle on standing.
- The particles pass through ordinary filter papers.
- They are clear and do not have color.
- They do not scatter light
Suspensions have the following properties:
- The particles dispersed are large
- They settle on standing.
- The particles do not pass through ordinary filter papers
- They do not pass through permeable membrane
- They are visible with microscope or naked eyes.
- They are cloudy
- Scatters light.
Colloids have the following properties:
- Their particles are between those in solutions and suspensions.
- Their particles do not settle on standing.
- Their particles pass through ordinary filter paper.
- They do not pass through permeable membranes.
- Scatters light

Answer:
4.113 × 10⁴ pounds per acre = 41,130 pounds per acre to the nearest pounds per acre
Step-by-step explanation:
9.46 × 10⁻¹ pounds of potatoes were produced for every 2.3 × 10⁻⁵ acre harvested. The average pounds of potatoes harvested per acre would be pounds of potatoes/acres harvested = 9.46 × 10⁻¹ pounds/2.3 × 10⁻⁵ acre = 4.113 × 10 ⁻¹⁻⁻⁵ = 4.113 × 10⁵⁻¹ = 4.113 × 10⁴ pounds per acre = 41,130 pounds per acre to the nearest pounds per acre.
