Perhaps I don't understand the question. You only need to choose one pair that adds to 16, any of {1, 15}, {3, 13}, {5, 11}, {7, 9}.
You can choose up to 4 numbers without getting a pair that adds to 16, so if you choose any 5 numbers, at least one pair of them will add to 16.
Answer:
Yes, we have enough money to pay for the groceries.
Step-by-step explanation:
We are given that Groceries cost $75. The tax rate is 5%.
We have to check that will the amount of $80 enough to pay for the groceries or not.
<em>For this we will firstly calculate the total cost of groceries after applying tax rate of 5% on groceries. </em>
Cost of groceries after applying tax rate is given by;
Since we know that by applying a tax on any item it's cost gets increased.
So, <u>Cost of groceries after tax</u> = Cost of groceries before tax + Amount of tax
Amount of tax = Tax rate
Cost of groceries
= 5%
$75
=
= $3.75
So, Cost of groceries after tax = $75 + $3.75 = $78.75
Since we have an amount of $80 with us which means that we are able to buy the groceries after giving tax on it as $78.75 < $80.
Therefore, yes we have enough money to pay for the groceries.

Answer:
3x² + 13x + 4
Step-by-step explanation:
3x³ - 2x² - 61x - 20
3x³ - 15x² + 13x² - 65x + 4x - 20
[3x²(x - 5) + 13x(x - 5) + 4(x - 5)]/(x-5)
3x² + 13x + 4
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base dimension and h=height
1) 10(12)/2=60mm^2
2) 14(34)/2=238in^2
3) 9.5(19.25)/2=91.4375yd^2
4) 4.9(23.7)/2=232.26m^2
5) 285=15b/2, 15b=578, b=38ft
6) 17h/2=18.7, 17h=37.4, h=2.2cm
7) 12.25b/2=128.625, 12.25b=257.25, b=21in
Well, it might not be important for most problems but..
If you're dividing, and the answer is a repeat..
You can estimate.
Example - 2.678 | You can estimate it to 2.68 and use that as an answer instead of a very long answer that's repeated.
I hope this helps.
