Answer:

Option B is the answer.

Step-by-step explanation:

We know in a right angle triangle when we apply Pythagoras Theorem, then

(Hypotenuse)² = ( side 1)² + (side 2)²

(A) set (1) ⇒ 6 cm, 7 cm, √12 cm

7² = 6² + (√12)²

49 = 36 + 12 = 48

49 ≠ 48     Therefore, its not the sides of a right triangle.

(B) Set (2) ⇒ 8 in, √29 in, √35 in

                    8² = (√29)² + (√35)²

                  64 = 29 + 35

                   64 = 64    So its a right angle triangle

(C) Set (3) ⇒ √3 mm, 4 mm √5 mm

         4² = (√3)² + (√5)²

         16 = 3 + 5

         16 ≠ 8    Therefore, its not a right angle triangle.

(D) Set (4) ⇒ 9 ft, √26 ft, 6 ft.

                      9² = (√26)² + 6²

                      81 = 26 + 36

                      81 ≠ 62   Therefore, its not a right angle triangle.

To be a right triangle, the hypotenuse^2 must equal side1^2 + side2^2

Only set 2 meets these conditions

8, sq root (29), sq root (35) then squaring these:

64, 29, 35

64 = 29 + 35

Answer: the speed of the current is 0.6 mph

Step-by-step explanation:

Let x represent the speed of the current.

James is kayaking. He can row 3 mph in still water. If he can travel 6 miles downstream. Assuming he went with the current, it means that his total speed while travelling downstream is (3 + x)

Time = distance/speed

Time taken to travel downstream is

6/(3 + x)

In the same amount of time, he can travel 4 miles upstream. Assuming he went against the current, it means that his total speed while travelling downstream is (3 - x). Time taken to travel upstream is

4/(3 - x)

Since the time is the same, then

6/(3 + x) = 4/(3 - x)

Cross multiplying, it becomes

6(3 - x) = 4(3 + x)

18 - 6x = 12 + 4x

4x + 6x = 18 - 12

10x = 6

x = 6/10

x = 0.6 mph

A certain bank offers a car loan with a fixed annual interest rate. Justine applied for the loan and used the entire amount to b
natita [175]

Answer: $10000

Step-by-step explanation:

From the question,

Principal = $43000

Time = 5 years

Rate = Unknown

Simple Interest = $51,600 - $43000 = $8600

We need to calculate the rate of interest which will be:

Interest = PRT/100

8600 = (43000 × 5 × Rate) / 100

Cross multiply

8600 × 100 = 215000 × Rate

Rate = 860000 / 215000

Rate = 4%

Assuming Justine borrowed $50,000 instead, the yearly Interest will be:

= (50000 × 5 × 4%)

= 50000 × 5 × 0.04

= $10000
