Is 7, 20, 25 a right triangle?

love history [14]

Answer:

The answer to your question is below

Step-by-step explanation:

Process

To answer if they are right triangles or not use the Pythagorean theorem which states that the square of the hypotenuse equals the sum of the square of the legs.

a) 25² = 20² + 7²

625 = 400 + 49

625 ≠ 449 It is not a right triangle

b) 26² = 24² + 10²

676 = 576 + 100

676 = 676 it is a right triangle

c) 13² = 8² + (√10)²

169 = 64 + 10

169 ≠ 74 it is not a right triangle

d) 52² = 48² + 20²

2704 = 2304 + 400

2704 = 2704 it is a right triangle

An online photo services charge $20 to make a photo book with 16 pages each extra page cost a dollar 75 the cost to ship the com

Alisiya [41]

Answer:

The expression to determine the total cost in dollars is $y=25+0.75x$ .

Step-by-step explanation:

Given:

Service charge to make a photo book = $20

Cost per extra page = $0.75

Cost to ship the complete photo book = $5

We need to write expression to determine the total cost in dollars.

Solution:

Let the number of extra pages be denoted by 'x'.

Also Let the Total cost be denoted by 'y'.

Now we can say that;

Total cost will be equal to sum of Service charge to make a photo book and Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.

framing in equation form we get;

$y=20+0.75x+5\\\\y=25+0.75x$

Hence the expression to determine the total cost in dollars is $y=25+0.75x$ .
