3. There are 48 dogs, 39 cats, and some birds at the pet store. There
are a total of 99 pets. How many
birds are at the pet store?

-

Answer : There are roughly 4 - 5 birds at the pet store

Step - by - step explanation :

Since there are 48 dogs, and 39 cats . . . in - order to find out how many birds there are we need to do . . .

48 + 39 = 87 <-- This is the total of cats and dogs combined

Now, because we know the remainder of animals at the store is birds we do . . .

99 <-- The total number of pets at the store - 87 = 12

There are 12 birds at the store

To find the remainder . . .

40/40 - 26/40 = 14/40 <-- The remaining amount of animals

I forgot how I got this but there are roughly 4 - 5 birds at the pet store

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
