Television
A=w *l=w* 5w=5w²
w=x+7, x- width of tablet
A=5(x+7)²=5(x²+14x+49)= 5x²+70x+245
A(television)=5x²+70x+245
"at least" means more or equal,so
5x²+70x+245≥1,050 - the answer
If tablet has width 8, x=8,
then
5*8²+70*8+245≥1050
1125≥1050 True,
so we can say
Yes, 8 in is a reasonable size for Adrew's tablet.
Answer:
a. $17.50
b. $11.25
c. $5
Step-by-step explanation:
First, set up an equation:
20 - 1.25x = m
Now let's substitute in for x (which is how many snacks you buy) to solve for m (the amount of money you have left):
20 - 1.25 ( 2 ) = m
20 - 2.50 = m
17.50 = m
20 - 1.25 ( 7 ) = m
20 - 8.75 = m
11.25 = m
20 - 1.25 ( 12 ) = m
20 - 15 = m
5 = m
The total of the fees can be found by adding their percentages, then making one multiplication. (It can also be found by computing the individual fees.) Of course, 3.3% = 3.3/100 = 0.033.
$300,000 × (0.7% + 0.3% + 2.3%) = $300,000 × 3.3% = $9,900
