Which set represents a pythagorean triple

1 answer:

AnnyKZ [126]3 years ago

5 0

Answer:

30, 40, 50 which is choice C

Step-by-step explanation:

Square the smaller two values (30 and 40)

30^2 = 900

40^2 = 1600

then add those results

900+1600 = 2500

Notice how 50^2 = 2500 as well. This shows us that 30^2 + 40^2 = 50^2 is a true equation. Both sides lead to the same result 2500. Therefore, a triangle with sides 30, 40, 50 is a right triangle. This is based on the 3-4-5 pythagorean triple, just each side has been multiplied by 10.

Can someone solve this problem for me

Aleks [24]

Answer:

(C) 90 $in^{2}$

Step-by-step explanation:

The figure is a combination of two parallelograms. So, to find the area of the whole figure, all you have to do is find the area of each parallelogram separately (they happen to be the same in this problem) and then add them up. The formula for the area of a parallelogram is <u>A = base*height</u>. In each parallelogram, the base is 15 in., and the height is 3 in. Therefore, the area of each parallelogram is 45 $in^{2}$ and the area of the whole figure is 90 $in^{2}$ .

Hope this helps :)

If Bank A charges a monthly service

Hatshy [7]

The bank which will charge a customer more in fees if she writes 18 checks per month, and by how much is Bank A by $0.30

<h3>How to write and solve equation?</h3>

let

x = number of checks

Bank A = 2.50 + 0.15x

= 2.50 + 0.15(18)

= 2.50 + 2.7

= $5.20

Bank B = 4 + 0.05x

= 4 + 0.05(18)

= 4 + 0.9

= $4.9

Difference in charges = $5.20 - $4.90

= $0.30

Please please please answer!!!!

(1) $12\frac{1}{2} -9\frac{1}{4}$

Let us convert mixed fraction into improper fraction.

$$12\frac{1}{2} -9\frac{1}{4}=\frac{25}{2} -\frac{37}{4}$

Make the denominator same.

$$=\frac{25\times2}{2\times2} -\frac{37}{4}$

$$=\frac{50}{4} -\frac{37}{4}$

$$=\frac{13}{4}$

Now convert improper into mixed fraction.

$$12\frac{1}{2} -9\frac{1}{4}=3\frac{1}{4}$

(2) $5\frac{3}{4}-2\frac{5}{12}$

$$5\frac{3}{4}-2\frac{5}{12}=\frac{23}{4}-\frac{29}{12}$

Make the denominator same.

$$=\frac{23\times3}{4\times3}-\frac{29}{12}$

$$=\frac{69}{12}-\frac{29}{12}$

$$=\frac{40}{12}$

$$5\frac{3}{4}-2\frac{5}{12}=3\frac{4}{12}=3\frac{1}{3}$

(3) $7\frac{1}{5}-3\frac{7}{10}$

$$7\frac{1}{5}-3\frac{7}{10}=\frac{36}{5}-\frac{37}{10}$

Make the denominator same.

$$=\frac{36\times2}{5\times2}-\frac{37}{10}$

$$=\frac{72}{10}-\frac{37}{10}$

$$=\frac{35}{10}$

$$7\frac{1}{5}-3\frac{7}{10}=3\frac{5}{10}=3\frac{1}{2}$

(4) $11\frac{2}{3}-8\frac{1}{2}$

$$11\frac{2}{3}-8\frac{1}{2}=\frac{35}{3}-\frac{17}{2}$

$$=\frac{35\times2}{3\times2}-\frac{17\times3}{2\times3}$

$$=\frac{70}{6}-\frac{51}{6}$

$$=\frac{19}{6}$

$$11\frac{2}{3}-8\frac{1}{2}=3\frac{1}{6}$
