Barb is making a bead necklace. She strings 1 white bead,then 3 blue beads,then 1 white bead,and so on. Write the numbers for th

nataly862011 [7]

The numbers for the first eight beads that are white are; 1, 5, 9, 13, 17, 21, 25, 29

<h3>Arithmetic Sequence</h3>

We are told that she strings in this order;

1 white
3 blue
1 white bead

Now, after the first white bead, the next white bead is the 5th bead in total.

This means the difference in interval between white beads is; 5 - 1 = 4 beads

Thus, the numbers for the first eight beads that are white are;

1, (1 + 4), (1 + 4 + 4), (1 + 4 + 4 + 4).....

Thus, we have;

1, 5, 9, 13, 17, 21, 25, 29

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

2/3(6h - 9) = 6

Step 2: Solve for h

[Division Property of Equality] Divide 2/3 on both sides: 6h - 9 = 9
[Addition Property of Equality] Add 9 on both sides: 6h = 18
[Division Property of Equality] Divide 6 on both sides: h = 3

A certain colony of bacteria triples in length every 10 minutes. Its length is now one millimeter. How long will it be in 40 min

Bumek [7]

Answer:

81mm

Step-by-step explanation:

the number of steps is small enough that we can simply list out each step

let the time elapsed be t and the original length be L ( = 1 mm)

when t = 0, L = 1mm

when t = 10, L = 3mm

when t = 20, L = 3 x 3 = 9mm

when t = 30, L = 9 x 3 = 27mm

when t = 40, L = 27 x 3 = 81mm

I need help with this tri trig I think it’s 55 but I don’t see the answer choice

babymother [125]

Answer:

m ∠ W is 58.2°

Step-by-step explanation:

Given:

XY = 15

WZ = 22

∠ XZY =25°

To Find:

m ∠ W = ?

Solution:

In right angle triangle Δ XZY, by Sine identity we have

$\sin Z= \frac{\textrm{side opposite to angle Z}}{Hypotenuse} \\\sin 25= \frac{XY}{XZ}\\0.4226=\frac{15}{XZ}\\\therefore XZ=\frac{15}{0.4226} \\XZ=35.49$

∴ XZ = 35.49

Now in right angle triangle Δ WZX, by tangent identity we have

$\tan W = \frac{\textrm{side opposite to angle Z}}{\textrm{side adjacent to angle Z}}\\\tan W = \frac{XZ}{WZ}\\\tan W = \frac{35.49}{22}\\\tan W = 1.6131\\\therefore W =\tan^{-1}(1.6131) \\W= 58.2\°$

∴m ∠W =58.2°
