Find PT length use other shape to help

Mathematics

Answer:

32

Step-by-step explanation:

The two shapes are similar, meaning the side lengths are scaled proportionally.  If you rotate the second shape to have both shapes facing in the same direction, you will see GK is corresponding with side QR. GK is 4 and it becomes 32 when scaled by 8. Side PT is corresponding with HI. Because side HI is equal to 4, using the knowledge above we know side PT is equal to 32.

Answer:

PT=32

Step-by-step explanation:

GHIJK ~ QPTSR means that: pentagon GHIJK is similar to pentagon QPTSR

With this information, we see that we will have to use proportions to find PT

GH ~ QP =  \frac{3}{24}

HI ~ PT =  \frac{4}{x}

IJ ~ TS =  \frac{x}{56}

JK ~ SR =  \frac{x}{40}

KG ~ RQ = \frac{4}{32}

Another way to find PT is by using the proportion scale of 8

We will use 8 because GH ~ QP =  \frac{24}{3} = 8 and KG ~ RQ = \frac{32}{4} = 8

So we multiply 4 and 8 to get 32

When comparing answers on a group assignment, Jenny and Jeremy found that their answers did not match. Part 1: Who do you believ
vitfil [10]
PART 1:

Jeremy gives the correct answer. 

The value of 0.41 [with a bar over the digit 4 and 1] shows that the digit 4 and 1 are reoccurring = 0.414141414141414141....

Jenny's assumption of 41/100 will give a decimal equivalency of 0.41 [without a bar over digit 4 and 1]. This value is not a reoccurring decimal value. 

PART 2:

The long division method is shown in the picture below

PART 3:

As mentioned in PART 1, the result of converting 41/100 into a decimal is 0.41 [non-reoccuring decimal] while converting 41/99 into a decimal is 0.41414141... [re-occuring decimal]. The conjecture in PART 1 is correct

Find c and round to the nearest tenth. thank you in advance
PSYCHO15rus [73]

Answer and Step-by-step explanation:

90ft = a

55ft = b

50ft = c

Plug into equation.

50^{2}  = 90^{2}  + 55^{2}  - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4

29.4° is the answer.

Find the interest rate r when p = 800, a = 2700, and t = 3.​
Vaselesa [24]

Answer:

r = 0.5 or 1/2

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)^t

Simply plug in our known variables:

2700 = 800(1 + r)³

Now we solve for <em>r</em>:

<em>Divide both sides by 800</em>

27/8 = (1 + r)³

<em>Take the cube root on both sides</em>

∛27/8 = ∛(1 + r)³

<em>Simplify</em>

3/2 = 1 + r

<em>Subtract 1 on both sides</em>

r = 1/2

r = 0.5
