A right triangle has a perimeter of 24 cm and a hypotenuse of 10 cm. Find the length of the other two sides.
jekas [21]

Answer:

One of the sides is 6 cm and the other is 8 cm

Step-by-step explanation:

Let's call the unknown sides a and b. From the perimeter information (24 cm) we have:

a + b + hypotenuse = 24

a + b + 10 = 24

a + b = 14

b = 14 - a

So now we can right the Pythagorean theorem as follows:

a^2 + b^2 = hypotenuse^2\\a^2 + (14-a)^2=10^2\\a^2+ 14^2-28\,a+a^2=100\\2\,a^2-28\,a +96=0\\2\,(a^2-14\,a+48)=0\\2\,(a^2-6\,a-8\,a+48)=0\\2(a\,(a-6)-8\,(a-6))=0\\2\,(a-6)\,(a-8)=0

and from this expression in factor form to be zero a must be 6 or a must be 8.

Therefore the solutions are a = 6 (and therefore b = 14 - 6 = 8)

or a = 8 (and therefore b = 14 - 8 = 6)

What does | 3+i | equal
prohojiy [21]
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number  z = x + iy,  [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i,  x = 3, y = 1    (Note y is what number that is attached to i)

[3 + i] = √(3^2 +1^2) = √10 = 3.162

The total rainfall in Zoe's town in April was 5 7/8 inches. The total in May was 2 1/8 inches less than in April. What was the t
Nataly_w [17]
1) Zoe's town
April = 5 7/8 inches
May = 2 1/8 inches less than in April

5 7/8 ⇒ ((5*8)+7)/8 = 47/8
2 1/8 ⇒ ((2*8)+1)/8 = 17/8

47/8 - 17/8 = 30/8 ⇒ 3 6/8 ⇒ 3 3/4 inches rainfall in May.

April rainfall : 5 7/8 inches
May rainfall : 3 3/4 inches

Greatest Prime number less than 50 is 47. So, 47 students plus 3 teachers. There is a total of 50 people going on the trip.
