Answer:

136.73972

Step-by-step explanation:

A=lw+l(w

2)2+h2+w(l

2)2+h2=6·5.2+6·(5.2

2)2+92+5.2·(6

2)2+92≈136.73972

Find missing number from letter n ! Please
Ira Lisetskai [31]

Answer:

1. n= 20 /13

2. n=10

3. n=35

4. n=9

That's all I could do, I got tired of typing lol

Step-by-step explanation:

1.  4/n=13/5 we cross multiply, (4)*(5)=13*n, 20=13n Flip the equation.  13n=20, divide 13 on both sides, 13n/13=20/13, n= 20 /13

2. 9/6= 15/n, we cross multiply 9*n=(15)*(6), 9n=90, Divide both sides by 9. 9n/9=90/9 n=10

3. 28/4=n/5 Cross-multiply, (28)*(5)=n*(4), 140=4n Flip the equation.4n=140 Divide both sides by 4. 4n/4=140/4 n=35

4. n/6=6/4 we cross multiply,n*(4)=(6)*(6), 4n=36, Divide both sides by 4 4n/4=36/4.  n=9

7 Point Question Tyler was trying to prove that all rhombuses are similar. He thought, “If I draw 2 rhombuses, I can find dilati
Viefleur [7K]

A rhombus can have the same shape and dimension as a square or a

parallelogram, therefore, all rhombuses are not similar.

  • A step in the proof that have flaws is <u>step 3</u>.

Reasons:

By reading through the given steps, we have, the first step that is incorrect

is step 3.

Step 3: The requirement for the similarity of two figures based on the

proportionality of the corresponding sides of the figures is related with

triangles as given by the triangle proportionality theorem.

This is so because, the lengths of the sides of a triangle depends on the

opposite interior angle, while the side of a rhombus can have a

combination of large length and and acute angle.

Two rhombuses that have proportional sides may be dissimilar,

because they can have different interior angles.

Therefore;

<u>The step in Tyler's proof that have a flaw is Step 3</u>

Answer:

b = \frac{1}{5}

Step-by-step explanation:

35b = 7

Divide both sides by 35.

b = \frac{7}{35}

Reduce the fraction \frac{7}{35} to the lowest terms by extracting and canceling out 7.

b = \frac{1}{5}

Hope it helps and have a great day! =D

HELP: The housing market in Dallas, Texas, experienced a 9.8% increase in the past year. If the median home price was $96,812 on
Wewaii [24]
1st step: find what is 9.8% of $96,812

9.8% = .098
(.098)(96,812)
= 9,487.576

2nd step: Add 96,812 and the result of the last step.

96,812 + 9,487.576
= 106,299.576

This rounded to the nearest dollar then equals 106,300 dollars
