harmaine spent a total of $20 at the grocery store. Of this amount, $9 she spent on fruit. What percentage of the total did she

zheka24 [161]

Answer:

45%

Step-by-step explanation:

First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.

$\frac{9}{20}$

For a percentage, we need a fraction out of 100. To do this, we can multiply the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.

$\frac{9}{20}*\frac{5}{5}=\frac{45}{100}$

A percentage is just the numerator of a number over 100 therefore it is equal to...

Let p: x < −3 Let q: x > 3 What is represented by p ∨ q?

anastassius [24]

Answer:

p v q = x < -3 or x > 3

Step-by-step explanation:

We are given

p: x < -3

q: x > 3

and we need to find p v q

v symbols represents disjunction and in simple terms it is called "or"

So, p v q represents either p holds or q holds

So, p v q = x < -3 or x > 3
