The ratio of the number of baskets made by to Tony to the number of baskets made by Colin is 2 to 3. Tony made 10 baskets.How many baskets did Colin make?
Answer:
I believe the answer would be 15
Step-by-step explanation:
This is because the ratio is 2 to 3 and you would divide it in half so you get one part then times it by three to get the second part of the ratio.
So it would be 10/2=5 then 5 times 3 to get 15. Therefore, 10 to 15
Answer:
15 baskets
Step-by-step explanation:
Step 1 : write a statement
Tony : Colin
2 : 3
10 : ?
Step 2: Cross multiply
i.e. 10×3=30
30÷2=15

1. Find the sum of the following AP:
2.7.12.....to 10 terms
06.17.28....to 100 terms
please answer
Answer:
245 and 55050
Step-by-step explanation:
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
In the first progression a₁ = 2 and d = 7 - 2 = 5, thus
[tex]S_{10}[/tex] = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ] = 5 × ( 4 + 45 ) = 5 × 49 = 245
-------------------------------------------------------------------------------
In the second progression a₁ = 6 and d = 17 - 6 = 11, thus
[tex]S_{100}[/tex] = [tex]\frac{100}{2}[/tex] [ (2 × 6) + (99 × 11) ]
= 50(12 + 1089) = 50 × 1101 = 55050

Step-by-step explanation:
define initial value
Answer:
the initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.

Answer:

Step-by-step explanation:
It's not -4.44, and if it was -3.14 it would be closer to the -3 tick on the line. With the negative square root of 17 being 4.12 it's not that either. -11/3 is 3.6666667 or something along those lines so it would be closer to the -4 tick on the line, so I'm pretty sure you got it.

Twelve more than a number is the product of -3 and 6. Translate using n
Answer: n + 12 = -18 or n + 12= -3(6)
Step-by-step explanation:
12 more than a number means 12 is added to the number so the expression will be n + 12 and the product of -3 and 6 is the same as -3 times 6 which is -18 . n + 12 has to equal -18 .
n + 12 = -18 now subtract 12 from both sides
-12 -12
n= -30
So the number is -30

How much should Jenna save up to prepare for car repairs and maintenance? (A lump sum emergency fund just for car repair/maintenance that may come up in the future)
Answer:
$500 per year.
Step-by-step explanation:
Car repairs and maintenance expense is based on the usage of car as well as its present condition. If the car is bought from showroom and is new then it will incur only small amount of expense as its maintenance but if the car is used by various owners then it is likely that maintenance expense can be huge. The average car repair expense is $500 to $800 per year depending on car condition. Since Jenna car is new she should keep the repair estimate to be minimum that is nearly $500 per year or $42 per month.
