)Marcus painted one-third of his bedroom in fourth-fifths of an hour. At this rate, how long would it take him the paint the entire room?

Answers

It will take 2.4 hours to paint the entire room.

Given that,

Marcus painted one-third of his bedroom in the fourth-fifths of an hour.

We have to determine,

At this rate, how long would it take him the paint the entireroom?

According to the question,

The value of time would it take him the paint the entire room is determined by the unitary method.

Marcus painted one-third of his bedroom in the fourth-fifths of an hour.

(1)/(3) \ part = (4)/(5) \ hour\n\n

Then, The time is taken to paint the entire room is,

= (4)/(5) * 3\n\n= (12)/(5)\n\n= 2.4 \ hours

Hence, It will take 2.4 hours to paint the entire room.

The first five terms of a sequence are 7,10, 13 , 16 and 19. which of the following functions define this sequence for all integers n>or equal to 1?A. f[n]= 3n=7
B.f[n]= 4+3n
C. f[n]= 4[3]^n-1
D.f[n]=7[3]^n-1

Answers

The correct option is D) f(n) = 4 + 3n.

Step-by-step explanation:

Given :

Arithmetic Sequence -- 7,10,13,16,19

Solution :

The explicit formula of arithmetic sequence is given by,

T_n = a+(n-1)d ------- (1)

where, common difference (d) = 10 - 7 = 3

first term (a) = 7

So from equation (1),

T_n = 7+(n-1)3 = 7+3n-3

T_n = 4 + 3n

Therefore, the correct option is D) f(n) = 4 + 3n.

Answer:

Option B is correct

For n\geq 1 , the function for the given sequence is defined as; f[n] = 4 +3n

Step-by-step explanation:

An arithmetic sequence is a sequence in which the difference between each consecutive term is constant.

An explicit formula for this arithmetic sequence given by;

a_n = a+(n-1)d where a represents first term

Since, the given sequences; 7 , 10 , 13 , 16 and 19

⇒ common difference(d) = 3 and a = 7

Since.

10 -7 = 3

13- 10 = 3  ....

The function which defined this sequence is;

f[n]=a_n = 7 +(n-1)(3)

using distributive property:

f[n] = 7 + 3n -3

f[n] = 4 +3n

therefore, the function for the given sequence for all integers n\geq 1 is;  f[n] = 4 +3n

you buy two rolls of wrapping paper. each roll has the same lateral surface area. what is the diameter of roll B?

Answers

The area of lateral surface is equal that the perimeter multiply by the length. So the lateral surface area of roll A is 3*π*30=90π. Roll B: d*π*24=24dπ. Put them together: 90π=24dπ. So d=3.75 in.
