The true statements are:

2) To find density, divide the mass by the volume.

3) To find mass, multiply the density times the volume.

5) To find volume, divide the mass by the density.

The equation for density is D=m/V (where D is density, m is mass, and V is volume).

To find the equation for mass, solve for the m variable in the equation by multiplying both sides by V. The equation is m=DV.

To find the equation for volume, solve for the V variable in the equation by multiplying both sides by V and then dividing both sides by D. The equation is V=m/D.

Hope this helps!!

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so

mamaluj [8]

Answer:

1) Is the pattern an arithmetic sequence?

Yes it is

2)Identify a and d.

a = First term = 2

d = Common difference = 2

3) Write the 50th term of the sequence.

50th term = 100

4) Find the total number of logs in the first 10 rows.

= 1010 logs

Step-by-step explanation:

Is the pattern an arithmetic sequence?

Yes it is

2) Identify a and d.

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,

The formula for arithmetic sequence =

an = a+ (n - 1)d

a = First term

d = Common difference

For the above question:

a = 2

d = Second term - First term

= 4 - 2

d = 2

3) Write the 50th term of the sequence.

Using the formula for arithmetic sequence

an = a+ (n - 1)d

a = 2

n = 50

d = 2

a50 = 2 + (50 - 1)2

= 2 + (49)2

= 2 + 98

= 100

The 50th term = 100

4)Find the total number of logs in the first 10 rows.

Sum of first n terms = n/2(a + l)

n = 10

a = first term = 2

We are told that there are 200 logs in the bottom row, hence:

l = last term = 200 logs

Hence,

Sn = 10/2×[ (2 + 200

= 5(202)

= 1010 logs

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$
