Lamar and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Lamar starts with 10 points, and his little brother starts with 20 points. Lamar gets 3 points for every successful shot, and his brother, since he is younger, gets 2 points for each successful shot. Eventually, the brothers will have a tied score in the game. How many points will they both have?
Answer:
If you add 3 to 18 it'll eventually lead to 24, as for 2 plus 20, if you add that up it also gets you to 24 which will make the game tied. And the tied score is 24.
Step-by-step explanation:
Each brother will need 2 additional shots!

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

Answer:
the answer is C
Step-by-step explanation:
first off find the common denominater (15)
how did the denominater become 15? multiply by 5 or 3
2/5 multiply both by 3 and multiply 1/3 by 5
you get 6/15+5/15 = 11/15
[tex] \frac{2}{5} + \frac{1}{3} [/tex]
to find:the simplest form.
solution:[tex] \frac{2 \times 3}{5 \times 3} + \frac{1 \times 5}{3 \times 5} [/tex]
[tex] = \frac{6}{15} + \frac{5}{15} [/tex]
[tex] = \frac{6 + 5}{15} [/tex]
[tex] = \frac{11}{15} [/tex]

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
I hope this is better than my last answer lol.. this hurt my head

Peter owns a candy store. His starting balance last month was $15,300. His ending balance was $12,500. What is Peter Burn Rate? 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

If the radius of a circle is doubled, how does the area of the circle change?
Answer:
Quadruple the size
Step-by-step explanation:
Explanation:
When you enlarge a linear measurement by a scale factor a the area changes by a scale factor a2
So when you double the radius. scale factor 2, the area is increased by a scale factor:
22=4
So the area is quadrupled in this case.
