Polygon ABCD reflects about line to make polygon EFGH. What is the length of ? A. 2 units B. 2.2 units C. 3 units D. 3.2 units
Mademuasel [1]

Answer:

A) LEngth of FG is 2 units

Step-by-step explanation:

Considering the diagram attached below.

Reflection of any polygon does not affects its length.

As it is given both polygons are reflection of each other so their sides are congruent.

AB ≅ EF = 3 units

BC ≅ FG = 2 units

CD ≅ GH = 2.2 units

DA ≅ HE = 3.2 units

A very large bag contains more coins than you are willing to count. Instead, you draw a random sample of coins from the bag and
Pie

Missing Details

Quarters  ≡ Dimes ≡  Nickels ≡  Pennies

23             ≡   29      ≡  17           ≡  38

Answer:

P(Q\ or\ P) = 0.5701

Step-by-step explanation:

Given

Quarters = 23

Dimes = 29

Nickels = 17

Pennies = 38

First, we calculate total number of coins

Total = 23 + 29 + 17 + 38

Total = 107

The probability of obtaining quarter (Q) of penny (P) is:

P(Q\ or\ P) = P(Quarters) + P(Pennies)

P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}

Take LCM

P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}

P(Q\ or\ P) = \frac{23 + 38}{107}

P(Q\ or\ P) = \frac{61}{107}

P(Q\ or\ P) = 0.5701

The diameter of the sun is about 1,391,000 kilometers, and the diameter of Venus is about 12,100 kilometers. About how many time
frez [133]

Answer:

<h3>A. 1.15 x 10^2 </h3>

Step-by-step explanation:

Given the following;

Diameter of the sun ds = 1,391,000 kilometers

Diameter of the Venus dv = 12,100kilometers

Taking the ratio of both diameters;

Ratio = Diameter of sun/Diameter of Venus

Ratio = 1,391,000/12,100

Ratio = 13910/121

Ratio = 114.958

Hence ds/dv = 114.958

ds/dv = 1.149 *10^2

ds/dv = 1.15*10^2

ds = 1.15*10^2 dv

Hence the diameter of the sun is 1.15*10^2 larger than that of the venus.

What is the difference between theoretical and actual radioactive decay?
pishuonlain [190]

Answer:

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and strong forces.[1]
