For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: total cost
We write the algebraic expression that models the problem.
We have then:
Simplifying we have:
Then, by the time the cost is equal to $ 300 we have:
From here, we clear the value of x.
Answer:
an algebraic expression for the problem is:
Answer:
1a+12/2
Step-by-step explanation:
1/2a+6
1/2a+6/1
1/2a+6/1*2
1/2a+12
1a+12/2

Step-by-step explanation:
We all know that area of triangle is base into hight upon 2.
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
