Answer:
<h3>There must be infinitely numbers different ones digits are possible in numbers that Larry likes.</h3>
Step-by-step explanation:
Given that my co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004.
<h3>To find that how many different ones digits are possible in numbers that Larry likes:</h3>
From the given "Larry only likes numbers that are divisible by 4."
There are many numbers with one digits in the real number system that could be divisible by 4 .
<h3>We cannot say the count,so it is infinite.</h3><h3>Hence there must be infinitely numbers different ones digits are possible in numbers that Larry likes</h3>
Answer: 90% decrease
Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.
Now to find the percent decrease, we divide the
amount of change by the original number.
The <em>amount of change</em> is the difference between the two numbers
which in this case is 2,000 - 200 and the original number is 2,000.
.
2,000 - 200 is 1,800.
So we're left with 1,800/2,000 and dividing
2,000 into 1,800 gives us 0.9.
Remember however that our problem is
asking for a <em>percent</em>, not a decimal.
So we need to write 0.9 as a percent and we can do
that by multiplying it by 100 and adding the percent sign.
So 0.9 becomes 90%.
So when a number changes from 2,000 to 200,
it has decreased by 90%.
$110.40 because 60% of $69 is $41.40. Then add $69 and $41.40.
Answer:
length = 23 inches; width = 18 inches.
Step-by-step explanation:
Length and width are found from their expressions after solving for x. The value of x can be found from ...
... overall area - cutout area = 148 . . . . . . square inches
... (2x -1)(x +6) - (2x -5)(x +2) = 148 . . . . . substitute length and width expressions. Each area is the product of length and width.
... 2x² +11x -6 -(2x² -x -10) = 148 . . . . . . . multiply binomials
... 12x +4 = 148 . . . . collect terms
... 12x = 144 . . . . . . . subtract 4
... x = 12 . . . . . . . . . . divide by 12
Then the overall length is ...
... 2x -1 = 2·12 -1 = 23 . . . inches
and the overall width is ...
... x +6 = 12 +6 = 18 . . . inches
The overall dimensions of the original mat are 23 inches by 18 inches.
