There are a lot of numbers you can think of, for example, 1030, or even 9939, but I don't recommend you put that ;)

Answer:

Number of People in the basketball game =A four digit number having 3 in the tens place.

Total number of digits in all={0,1,2,3,4,5,6,7,8,9}=10

So, Required Number,that is number of people at the basketball game which is a four digit number,also digits can repeat

                          =(0 can't be at Unit place ,so first digit that is number at thousands place can be selected in 9 ways)(Number at Hundred place can be selected in 10 ways )(3 in tens place)( Number at Unit place can be selected in 10 ways )

=9939(Maximum People)

Total number of four digit numbers , if these condition are given

=9×10×1×10

=900

Please help. there is a picture below
OleMash [197]
Two triangles are similar if and only if all corresponding angles are equal (congruence), even if the corresponding sides are equal or not, therefore the answer is true because ΔJKL and ΔRST are similar and the statement above demands that "it must be", namely, this is a sufficient condition.

Determine whether the sequence below is a geometric sequence and, if so, find a formula that describes the sequence. 1, 3, 9, 27
r-ruslan [8.4K]

a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number

might be confusing so here's an example

1,2,4,8,16

each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio

formula for geometric sequence is

a_n=a_1(r)^{n-1}

where a_n is nth term

a_1 is first term

r is teh common ratio

n=which term


in our example

1,3, 9, 27, 81

each term is being multiplied by 3 so it is a geometric sequence and thus r=3

also first term is 1 so a_1=1

so the formula is a_n=1(3)^{n-1} or in function notation f(n)=1(3)^{n-1}

Lelechka [254]

Answer:

Step-by-step explanation:

so the least common denominator is 12, so:

multiply 3/4ab by three, which equals: 9/12ab

9/12ab-5/12ab = 4/12ab, or 1/3ab
