The diameter of a certain bacterium is about 0.00005 meters Use scientific notation

1 answer:

4 0

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
so
0.00005 meters --------> 5 x 10^-5 meters

State the converse, contrapositive, and inverse of each of these conditional statements a) If it snows tonight, then I will stay

marissa [1.9K]

Step-by-step explanation:

Consider the provided information.

For the condition statement $p \rightarrow q$ or equivalent "If p then q"

The rule for Converse is: Interchange the two statements.
The rule for Inverse is: Negative both statements.
The rule for Contrapositive is: Negative both statements and interchange them.

Part (A) If it snows tonight, then I will stay at home.

Here p is If it snows tonight, and q is I will stay at home.

Converse: If I will stay at home then it snows tonight.

$q \rightarrow p$

Inverse: If it doesn't snows tonight, then I will not stay at home.

$\sim p \rightarrow \sim q$

Contrapositive: If I will not stay at home then it doesn't snows tonight.

$\sim q \rightarrow \sim p$

Part (B) I go to the beach whenever it is a sunny summer day.

Here p is I go to the beach, and q is it is a sunny summer day.

Converse: It is a sunny summer day whenever I go to the beach.

$q \rightarrow p$

Inverse: I don't go to the beach whenever it is not a sunny summer day.

$\sim p \rightarrow \sim q$

Contrapositive: It is not a sunny summer day whenever I don't go to the beach.

$\sim q \rightarrow \sim p$

Part (C) When I stay up late, it is necessary that I sleep until noon.

P is I sleep until noon and q is I stay up late.

Converse: If I sleep until noon, then it is necessary that i stay up late.

$q \rightarrow p$

Inverse: When I don't stay up late, it is necessary that I don't sleep until noon.

$\sim p \rightarrow \sim q$

Contrapositive: If I don't sleep until noon, then it is not necessary that i stay up late.

$\sim q \rightarrow \sim p$

I need help on this it is a fraction subtract another fraction which is negative thx to whoever helps 5/7-(-1/7)

Sav [38]

Answer:

$\frac{5}{7}-(-\frac{1}{7})=\frac{6}{7}$

Step-by-step explanation:

To evaluate :

$\frac{5}{7}-(-\frac{1}{7})$

Solution:

Two negatives multiply to become a positive.

Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.

⇒ $\frac{5}{7}+\frac{1}{7}$

Since the denominators are same for both fractions, so we simply add the numerators.

⇒ $\frac{5+1}{7}$

⇒ $\frac{6}{7}$ (Answer)

Peyton has 2 pizzas.each pizza is cut into 10 equal slices.she and her friends eat 14 slices. what part of the pizzas did they e

WINSTONCH [101]

Since Peyton has 2 pizzas and each is cut into 10 equal slices that would mean 2x10 which is 20 and then it says she and her friends eat 14 slices which means take away 14 minus 20 which is 6 so the decimal for only 6 would be 0.6 which is the answer. Hope this helped.
