Answer 1

Answer:

Triangle ABC and triangle EDF

Answer 2

The similar triangles are Δ ABC ~ Δ EDF ~ Δ GHI, both the triangles are similar to Δ ABC.

What are similar triangles?

Triangles are similar when their corresponding sides are equal ratios and their corresponding angles are congruent.

Given are triangles, Δ ABC, Δ EDF and Δ GHI,

Since, in Δ ABC and Δ EDF, two angles are shown congruent therefore, both are similar.

Also,

In Δ GHI,

∠ G + ∠ I = 129°

∠ H = 180° - 129°

∠ H = 43°

Since, we get, two angles congruent in both triangles Δ EDF and Δ GHI

Therefore, both the triangles Δ EDF and Δ GHI are similar,

Now,

Since, Δ ABC ~ Δ EDF and Δ EDF ~ Δ GHI,

Therefore, Δ ABC ~ Δ EDF ~ Δ GHI,

Hence, the correct option is "Both"

Since the scale factor is 4:1, you need to divide each side by 4.

Also you can clearly rule out answer choices b and c because they just don’t make since since the object is smaller than the scale drawing.

20 points The supply and demand curves for a new style of silver earrings are shown. Where is the equilibrium point?

Answers

Answer:

It's the dot that's right in the middle of the rest, where the two lines meet.

Step-by-step explanation:

That's the equilibrium point.

The equilibrium point of the given graph is at (35, 90)

What are supply and demand curves?

The demand curve shows the quantities of a particular good or service that buyers will be willing and able to purchase at each price during a specified period. The supply curve shows the quantities that sellers will offer for sale at each price during that same period.

Given that, the supply and demand curves for a new style of silver earrings are shown.

We need to find the equilibrium point,

We know that, On a demand and supply graph, the equilibrium point can be found where the demand and supply curves intersect. Price is on the axis on both the demand and supply curves, and quantity demanded is on the axis.

In our graph, the curves are intersecting at (35, 90)

Hence, the equilibrium point of the given graph is at (35, 90)

suncatchers that brings the average cost below $22.50.
The minimum number of suncatchers that brings the average cost below

Answers

Answer:

Step-by-step explanation:

fixed cost = 100

variable cost = 13

soooo....

cost = (13x + 100)/x

the questions wants to know when cost < 22.50

22.5 > (13x+100)/x

look at graph attached ;)

it looks to me like it's at 11

22.5 > (13(11) + 100) / 11

22.5 > 22.09

try 10

22.5 > (13(10) +100)/10

22.5 > 23 not true so yes.. 11 is when the cost goes below 22.50

Jennifer purchased for 2$ and p pounds of sliced turkey at 5$ per pound for a total of $13.25. Which equation represents jennifer's purchase from the grocery store?

Answers

Answer:

$2 + $5p = $13.25

Step-by-step explanation:

Given that:

Initial purchase = $2

Pound of sliced turkey = p

Cost per pound of sliced turkey = 5$

Total amount spent = $13.25

Jennifers purchase from grocery store :

Initial purchase + (pound of sliced turkey * cost or pound) = total amount spent

$2 + $5p = $13.25

Find the measure of each numbered angle

Answers

1:81 Degrees
2:109 Degree
3&4:90 Degrees

Answer:

1. 71 degrees 2. 109 degrees 3. 90 degrees 4. 90 degrees

Step-by-step explanation:

109 + 71 = 180 (straight line)

so the other side (under) of 109 degrees is 71 degrees. That angle is the same angle as 1 because that same line (transversal) runs through both parallel lines.

The angle diagonal from 2 is 109 because it mirrors the same measurements as the one on the left. Angle 2 is the same angle as 109 degrees because it's a vertical angle. All vertical angles are equal.

Because the same line on the bottom runs through the parallel lines then the same angles apply to both on the bottom. The right one is a 90 degree angle

which makes both 3 and 4 90 degrees because 90 + 90 equals a straight line 180 degrees.

Suppose there is a game of chance that you would like to play. It costs $3 to play one time. There are 100 $1 bills, 20 $5 bills, 3 $20 bills, and 1 $100 bill in a box. You may reach into a box without looking and select one bill. Is this a fair game? Why or why not?

Answers

Answer:

1. It is not a fair game.

2. The game is not fair because the probability of winning and the probability of losing are not equal. In a fair game, the probability of winning is equal to the probability of losing. In this game, the probability of losing is 0.81 or 81%, while the probability of winning is 19% (100 - 81).

Step-by-step explanation:

Cost of playing the game one time = $3

Total number of bills in the box = 124 (100+20+3+1)

Chance of losing is represented by 100 of $1 bills = 100/124 = 0.81 or 81%

Chances of losing are represented by 20 of $5 bills, 3 of $20 bills, and 1 $100 bill = 0.19 or 19% (20/124 + 3/124 + 1/124).
