Answer:

Step-by-step explanation:

First, you gotta work out the hypotenuse of ABC, which is AC.

To do that, you need to figure out the scale factor between the two right-angled triangles. You can do that for this question because this is a similar shapes question.

12.5/5 = 2.5

The scale factor length between the two triangles is 2.5.

You can use 2.5 now to work out AC, so AC would be 13 x 2.5, which gives 32.5.

Now that you've got the hypotenuse and BC of ABC, you can use Pythagoras's theorem to work out the length of AB

Pythagoras's theorem = a^2 + b^2 = c^2

a = BC = 12.5

b = AB = we need to work this out

c = AC (the hypotenuse we just worked out) = 32.5

12.5^2 + b^2 = 32.5^2 Let's both simplify and rearrange this at the same time so that we have our b on one side.

b^{2} = 1056.25 - 156.25

b = \sqrt{(1056.25 - 156.25)}

b = \sqrt{900}

b = AB = 30  We've found b or AB, now we can work out the perimeter of ABC.

Perimeter of ABC = AB + BC + AC

= 30 + 12.5 + 32.5

= 75  Here's the perimeter for ABC.

The jeweler buys gold for 1235.55 per ounce and resells it for 1376.44 per ounce how much profit does the jeweler make from buyi
AnnZ [28]

Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce

<u>Solution:</u>

Given that

Price at which jeweler buy gold = 1235.55 per ounce

Price at which jeweler resells gold = 1376.44 per ounce

We need to calculate profit.

Buying price of 1 ounce of gold = 1235.55

Reselling price of 1 ounce of gold = 1376.44  

<em>Profit = Reselling price – buying price</em>

So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89  

Hence profit made by Buying and Selling gold will be 140.89 per ounce

Find the length of GI in the triangle below. Show your work.
love history [14]

Answer:

<u>The length of GI is 90.06 units</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

<u>GI = √ 8,110.8 = 90.06 units</u>

The graph below shows the distance, y, in miles, of a bee from its hive, for a certain amount of time, x, in minutes:Based on th
zhannawk [14.2K]

Answer:

C. 4 miles; it represents the original distance of the bee from its hive

Step-by-step explanation:

We are given,

The graph showing the distance between a bee hive for a certain amount of time.

Now, from the graph, we see that,

When the time is 0 mins, then the distance from the bee hive is 4 miles.

<em>Thus, the initial value of the graph is 4 miles and it represents the original distance of the bee hive from the hive.</em>

So, option C is correct.

The net of the figure shown is made of which set of
vodka [1.7K]

Answer:

Step-by-step explanation:

The sides of the base are each 5 inches. We see 4 right angles so that we are dealing with a square.

The triangles look to be isosceles. In any event there are 4 of them. So the answer is the 3rd one down.
