Answer:a=3.6 and b=4.8

Step-by-step explanation:(a^2)+(b^2)=(c^2)

Where c is hypotenuse is equal to 6. A right triangle is also known as a 3,4,5 triangle where the 2 legs are 3 and 4 and hypotenuse is 5. Find the factor in size difference by dividing your hypotenuse of 6 by the hypotenuse of 5 you get 1.2. Now multiply the 3 and 4 by 1 2 to get your answers of 3.6 and 4.8.

To check work simply plug in your legs as a and b

(3.6^2)+(4.8^2)=(6^2)

(12.96)+(23.04)=(36)

Vlad1618 [11]

Decibel is directly proportional to number of cars passing the point. That is,

69 db ----- 139 cars
x db ----- 17 cars

x = number of cars passing the point per minute on a weekend.

Then,
x= (69*17)/139 = 8.43 db ≈ 8 db

How many solutions will each system of linear equations have? Match the systems with the correct number of

JulsSmile [24]

Answer:

Step-by-step explanation:

Given that,

y = x + 6 equation 1

3x - 3y = -18. Equation 2

Substitute equation 1 into equation 2

3x-3(x+6) = -18

3x - 3x - 18 = -18

-18 = -18

Therefore, it has no solution. Check attachment for echelon matrix solution

B. y = -2x + 5 equation 1

2x + y = -7. Equation 2

Substitute equation 1 into 2

2x -2x + 5 = -7

5 = -7

Since the equation is not balance, then, it has infinite numbers of solution.

C. y = -4x + 11. Equation 1

6x + y = 11. Equation 2

Substitute equation 1 into 2

6x - 4x + 11 = 11

2x = 11 - 11

2x = 0

x = 0

Also, y = -4x + 11

y = 0 + 11 = 11

Then, this has a unique solution I.e. one solution.
