<h3>What is scientific notation?</h3>

Scientific notation is simply a way of expressing numbers that are too large or small to be written in decimal form.

It may be referred to as standard index form or scientific form.

From the information given, we have;

a. 0. 000003 is written in standard form as;

= 3 × 10^-6 × 3 × 10^6

= 3 × 10^-6 + 3

= 3 × 10^0

= 3

b. 56, 000, 000. 00 is written in standard form as;

= 5. 6 × 10^7 × 6 × 10^-7

= 33. 6 × 10^7 -7

= 33. 6 × 10^0

= 33. 6

c. 8. 0 × 10^-3 × 7. 2 × 10^5

= 57. 6 × 10^-3 + 5

= 57. 6 × 10^2

d. 4. 0 × 10^-3 × 4. 0 × 10^-4

= 4. 0 ^ -3 +(-4)

= 4. 0 × 10^-7

e. 7. 0 × 10^3 × 7. 0 × 10^4

= 7. 0 × 10^ 3-4

= 7. 0 × 10^-1

Thus, scientific notation is also referred to as standard form.

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. What is the unit rate at which Martin paints in walls per gallon?
Papessa [141]

Answer:

The unit rate is 32/25 Walls per gallons.

Step-by-step explanation:

Gallons of paint used by Martin =  5/8 gallons

Portion of wall Martin wants to paint in pints = 4/5 wall.

Rate at which Martin paints the wall: Rate =  Portion of wall covered/Paints Used.

Rate = 4/5 Gallons/5/8 Gallons = 32/25 Wall Gallons.

Solve problem A and B please!!
Nana76 [90]

Answer:

a. Isosceles + Acute

b. Scalene + Right

Step-by-step explanation:

a. The side markers show that 2 sides are equivalent in length, making it isosceles. The angles are all noticeably under 90 degrees, resulting in it being acute.

b. There are no side markers whatsoever, making it scalene. There is a right angle marker, resulting in the triangle being right.

Write 85% as a fraction in simplest form.
pav-90 [236]

Answer:

17/20

Step-by-step explanation:

85% can easily be written as 85/100 and this is true, but we have to simplify to the simplest form.

An easy way to simplify is to divide the numerator and denominator by the GCF (Greatest Common Factor)

The GCF of 85 and 100 is 5.

85 ÷ 5 = 17

100 ÷ 5 = 20

We can no longer simplify 17/20 because 17 is prime so your final answer is 17/20!

Hope you have a good day and luck in finding good memes!
