Darya [45]
Find the GCF of 24 and 30

  24                30
1×24              1×30
2×12             2×15
3×8               3×10
4×6               5×6

The common factors are 1, 2, 3, and 6

That means we can make 6 necklaces, each necklace with 4 jade beads and 5 teak beads.

How can i estimate a number from a bar graph??
olga55 [171]
You should first find out what lines are what,
Like for example, If you had 5 - 10 - 15 as the Y Lines and the bar was between 5 and 10 then your best bet would be to estimate what the middle of 5 and 10 is which would be 7 or 8.

How long does it take to double a $1,000 investment that pays 6.5% annual interest, compounded monthly?
ahrayia [7]
2p=p(1+0.065/12)^12t
2=(1+0.065/12)^12t
Solve for t
T= [log(2)/ log(1+0.065/12)] /12
T= 10.7 years or if you want to round it would be 11

Answer: 10.7 years or 11 years

Answer: You can use the compound interest formula: A=P(1+interest)^n

A=the new capital
P=the capital invested
n= the #of monthly


Hope this helps (:

State the Lagrange Theorem, and find the order of all possible subgroups of a group of order 5. The same question of a group of
oksian1 [2.3K]

Answer:

  Lagrange Theorem

Step-by-step explanation:

The Lagrange Theorem:

Let G be a finite group and T be a subgroup of G. Then the order of T divides the Order of group G.

This can be written as:

If T \subset G, then, o(T)|o(G).

Possible Subgroups

Now, we are given a group with order 5. We have to find all possible subgroups.

So, the possible subgroup are: groups with order 1, group with order 5

We are given a group with order 6.

Possible subgroups are: group of order 1, group of order 2, group of order 3 and group of order 4.
