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

Scarlett is working two summer jobs, making $13 per hour landscaping and making $8 per hour clearing tables. In a given week, sh
dolphi86 [110]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x ----> the number of hours landscaping

y ---->   the number of hours clearing tables

we know that

she can work a maximum of 12 total

so

x+y\leq 12 ----> inequality A

she must earn a minimum of $120

so

13x+8y\geq 120 ----> inequality B

Solve the system of inequalities by graphing

The solution is the triangular shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (the ordered pair lie in the shaded area of the solution set)

One possible solution is the point (10,1)

The point (10,1) lie in the shaded area

That means

The number of hours landscaping is 10 and the number of hours clearing tables is 1
