Uncle Drew scored 28 points in 5 5/6 minutes during a game of basketball. How many points did he average per minute during that 5 5/6
Answer: 48 points per minute
Step-by-step explanation:
28 divided by 5 and 5/6
= 28/1 ÷ 35/6
Dividing fractions is the same as multiplying by the reciprocal
= 28/1 * 6/35
= (28*6)/35
= (4*6)/5 --> simplify by reducing by 7
= 24/5 --> to mixed fraction. 4 4/5 = 4 and 4/5 = 4.8 points per minute

Click this link to open the Business Financials Part 2 Study Guide to view the formula used for this problem! Type a comma to separate the digits and type the $ symbol when you enter your answer as shown below: Example: $15,300
The burn rate is a value gotten per time, since the time is 1 month, and the difference between the start and ending balances is $2,800
Hence the burn rate is $2,800 per month
Rate of an expressionGiven Data
Starting Balance = $15,300
Ending Balance = $12,500
Duration = 1 month
Let us find the difference between the starting and the ending balance
= $15,300 - $12,500
= $2,800
Now we have the difference in amount, hence the burn rate will be
Burn Rate = $2,800 per month

Write an expression that describes the number of tiles for any stage in the visual pattern.
The number of tiles at any stage can be described with the expression below:
aₙ = 2 + 4n
From the diagram the number of tiles increase by 4 . Therefore, the expression that describe this pattern can be gotten by using arithmetic progression.
Arithmetic progression formulaAP = a + (n - 1)dwhere
a = first term
d = common difference
n = number of terms

Answer:
1.5
Step-by-step explanation:
First I convert it using the negative exponent rule
so 10^-7 becomes
1
------
10^7
(Dont ask how the negative exponent rule works i have no clue to be honest)
Now we have to do the 10^7
10^7 = 10000000
So the fraction is now
1
------------------------
10000000
What we have above equals 0.00000010
So we got that part now we have to do
5 * 0.00000010 = 0.00000050
So now we have (0.00000050) x ( 3 x 10^6)
Its fairly easy from here
first we do
10^6 = 1000000
then we do
3x1000000 = 3000000
Now we have
(0.00000050) * (3000000)
The parentheses are useless at this point so we can just remove them
0.00000050 * 3000000 which gets us to.. 1.5
