Answer:
1.58
Step-by-step explanation:
Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.
We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.
Plug both the plus and the minus versions into your calculator and...
There's no such thing as negative time, so -2.02 is automatically disqualified, leaving 1.58 as the answer.
Hope this helps, let me know if I missed anything!
Answer:
9.9 cups
Step-by-step explanation:
5/6 times 12 equals 9.9
Let the number of cards equal x.
Set up an equation for both companies, set equal to each other and solve for x.
0.10x + 12 = 0.12x + 10
Subtractb0.10x from both sides:
12 = 0.02x + 10
Subtract 10 from both sides:
2 = 0.02x
Divide both sides by 0.02:
X = 2/0.02
X = 100
100 cards would be the same price for both companies.
Answers:
mode = 1
range = 5
-----------------------------------------
Explanation:
The mode is 1 because it is the most frequent value. It shows up four times compared to the other values (5,6) which only show up once and the value 4 only shows up twice.
The range is 5 because we subtract the max and min values to get 5.
In other words,
Range = Max - Min
Range = 6 - 1
Range = 5
