Ally's science class was looking at bacteria through a microscope. Ally's teacher said some bacteria can be as small as 0.00365
mamaluj [8]

The length of the bacteria should be written in scientific notation.

0.00365 in scientific notation = 3 × 10^-3

Given.

length of the bacteria in decimal = 0.00365 cm long

Scientific notation is written in the format x × 10ⁿ

where,

x = any number between digit 1 and 10

n = exponent (positive or negative).

  • To have a negative exponent value, move decimal to the right

  • To have a positive exponent value, move the decimal point to the left.

In this case, the nearest significant value is 3

So move the decimal point three times to where 3 is

That is,

0.00365 = 3.65

Since the decimal point is moved to the right 3 times, n = - 3

we have 10^-3

Therefore,

0.00365 in scientific notation = 3 × 10^-3

BRAINLIST! HELP ME. CHOSE ANY QUESTION
Sav [38]

Answer:

Spicy-level question=1485

Step-by-step explanation:

If i read the numbers right you just have to multiply LxWxH which is 15x11x9 which equals 1485.Then you have to multiply 1485 by .50 which equals 742.5.Then you just move up the decimal one space to the right so then it will be 74.25. So i would think it would cost $74.25.

Sorry if i'm wrong

Write the value of n that makes statement true (3+n)+7=3+(6+7)
8_murik_8 [283]

Answer: n = 6

Step-by-step explanation:

First lets combine like terms

(3 + n) + 7 = 3 + (6 + 7)

10 + n = 16

Now let’s subtract 10 on each side to isolate x

N = 6

Now let’s check our work by inputting x just to make sure

(3 + 6) + 7 = 3 + (6 + 7)

9 + 7 = 3 + 13

16 = 16

So we are right!

Which verb agrees with its subject Your friends or their guest __________ cooking the meal. a. have been b. were c. are d. is
netineya [11]
The correct answer to the question above is (c.) are. The verb "are" agrees with its subject in the sentence above that says: "Your friends or their guest ARE cooking meal." That is because cooking is present and the friends and the guests are plural.
