Are these numbers a Pythagorean triple? yes or no

Mathematics
1 answer:
Illusion [34]3 years ago
3 0

Answer:

Yes

Step-by-step explanation:

You know if the numbers are in a Pythagorean triple if the sum of the squares of the two smaller numbers is equal to the square of the largest number according to the Pythagorean Theorem: a^2+b^2=c^2.

Here, a = 15 and b = 20. Let's see if: 15^2+20^2 equals 25^2.

15^2 = 225

20^2 = 400

15^2 + 20^2 = 225 + 400 = 625

25^2 = 625

Since 15^2 + 20^2 does indeed equal 25^2, we know that this is a Pythagorean triple.

Hope this helps!

A certain company manufactures skateboards and rollerskates. It takes them 2 units of labor and 1 unit of materials to produce a
Alisiya [41]

Answer: The company should produce 7 skateboards and 16 rollerskates in order to maximize profit.

Step-by-step explanation: Let the skateboards be represented by s and the rollerskates be represented by r. The available amount of labour is 30 units, and to produce a skateboard requires 2 units of labor while to produce a rollerskate requires 1 unit. This can be expressed as follows;

2s + r = 30 ------(1)

Also there are 40 units of materials available, and to produce a skateboard requires 1 unit while a rollerskate requires 2 units. This too can be expressed as follows;

s + 2r = 40 ------(2)

With the pair of simultaneous equations we can now solve for both variables by using the substitution method as follows;

In equation (1), let r = 30 - 2s

Substitute for r into equation (2)

s + 2(30 - 2s) = 40

s + 60 - 4s = 40

Collect like terms,

s - 4s = 40 - 60

-3s = -20

Divide both sides of the equation by -3

s = 6.67

(Rounded up to the nearest whole number, s = 7)

Substitute for the value of s into equation (1)

2s + r = 30

2(7) + r = 30

14 + r = 30

Subtract 14 from both sides of the equation

r = 16

Therefore in order to maximize profit, the company should produce 7 skateboards and 16 rollerskates.

I need help going through the steps of a problem please tell steps and not just answer
mezya [45]

Answer:

x = 5/7

Step-by-step explanation:

4 (0.25 - 2) = x - 0.75 (16 - 8x)

1 - 8 = x - 12 + 6x

1 - 8 + 12 = x + 6x

5 = 7x

5/7 = x
