Answer:

see explanation

Step-by-step explanation:

The n th term (explicit rule) of a geometric sequence is

a_{n} = a₁ (r)^{n-1}

where a₁ is the first term and r is the common ratio

here a₁ = 60 and r = \frac{12}{60} = \frac{1}{5}, hence

a_{n} = 60 (\frac{1}{5}) ^{n-1}

Answer:

60(1/5)^(n-1).

Step-by-step explanation:

The common ratio  r   is 12/60 = 12/5 / 12  = 12/25 / 12/5 = 1/5.

The first term a1 = 60 so the explicit rule is

a1 * r^(n-1)

= 60(1/5)^(n-1).

What is the width of the ornament at the volume of 2664.31 cm (use 3.14 for)
Aloiza [94]

Answer:

33.6

Step-by-step explanation:

this is a circle

so

the area of a circle = pi x radius squared(since it's a 2-D shape)

but this is 3-D

so

V = 2664.31 = (4/3)(\pir^{3})

you could also use

A = ³√(36 * π * V²) when A is the surface area

but those are too long, so let us just use the answer choices

V = 3.14 x answer choice x radius sqaured

V = 3.14 x 8.6 x radius sqaured

2664.31 = 3.14 x 8.6 x radius sqaured

radius sqaured =  2664.31/3.14 x 8.6

radius sqaured =  2664.31/27.004

radius sqaured can't be made with this

lets skip V

radius sqaured =  2664.31/3.14 x 17.2

radius sqaured = 2664.31/54.008

since 27.004 didn't work, and 54.008 is 2 times as that

radius sqaured = 2664.31/3,14 x 33.6

radius sqaured =  2664.31/105.504 ≈ 25

25 square rooted is 5

so

33.6

Mr. Gardner is making 6 treat bags. He has 185 chocolate-covered raisins to share evenly among the treat bags.
Degger [83]
To find out the answer, we need to divide 185 by 6.

185÷6=30 with a remainder of 5.

There are going to be 30 <span>chocolate-covered raisins in each bag, with 5 of them left over.

I hope this helps.</span>

The graph below shows how far a ship is traveling in a certain amount of time.
olga2289 [7]

Answer:

100 miles

Step-by-step explanation:

Remark

All you need do is start at 4 hours on the y axis and go right until you hit a dot. When you do, go down until you hit a number on the x axis.

It helps if you mark up the graph.

Go right from 4

You hit a dot

Look down.

You should see 100. That's how far you go in 4 hours.

Note

This is an odd graph. Usually time is on the x axis.

A basketball player claims to make 47% of her shots from the field. We want to simulate the player taking sets of 10 shots, assu
Molodets [167]

Answer:

0.9 or 90%

Step-by-step explanation:

The probability of shot is 47%

The probability of no shot is 100 -47 = 53%

The dot plot is made from the 10 repeated shots which recorded 25 scores.

The number of dots on the fifth tick is 9 of 10 shots

therefore; 9/10 = 0.9, which 90 in percentage.
