Which of the following is not a Pythagorean triple?

Answer:

7.722cm^2

Step-by-step explanation:

area of square=l^2=6^2=36cm^2

area ofcircle=π(d÷2)^2=3.142(6÷2)^2=3.142×9=28.278cm^2

where d=l=6cm

area of shaded =area of (square-circle)=36-28.278=7.722cm^2

The intensity of the sound of a jet plane would be 100 w/m² for a sound level of 140 dB

An equation is an expression that shows the relationship between two or more numbers and variables.

The sound level β, hence:

[tex]\beta =10log(\frac{I}{I_o} )\\\\I_o=10^{-12},hence:\\\\140 =10log(\frac{I}{10^{-12}} )\\\\I=100\ w/m^2[/tex]

The intensity of the sound of a jet plane would be 100 w/m² for a sound level of 140 dB

Answer:

x = 38°

Step-by-step explanation:

this is a four-sided polygon, so the sum of the interior angles measures 360 degrees; formula is (n - 2) · 180 where 'n' is the number of sides

add all four expressions and set equal to 360

5x - 33 + 5x + 13 = 360

10x - 20 = 360

10x = 380

x = 38

check by plugging 38 into each expression to make sure the total is 360

starting in upper left and moving clockwise, the angles are: 75°, 82°, 114°, 89°

  a: 0; b: 1; c: 1; d: ∞; e: 0; f: ∞

Step-by-step explanation:

Simplify the expressions to put the left and right in the same form. Then compare. If the x-coefficients are the same, there will be 0 or ∞ solutions. If they are different, there will be 1 solution.

If the x-coefficients are the same, look at the constants. If they are different, there will be 0 solutions. If they are the same, there will be ∞ solutions.

Answer:

a = −1 or a = 7

Step-by-step explanation:

Let's solve your equation step-by-step.

( a − 7 ) ( a + 1 ) = 0

Step 1: Simplify both sides of the equation.

a^2 − 6a − 7 = 0

Step 2: Factor left side of equation.

( a + 1 ) ( a − 7 ) = 0

Step 3: Set factors equal to 0.

a + 1 = 0 or a − 7 = 0

a = −1 or a = 7

x = 12

Step-by-step explanation:

By the alternite intereor angle therom, the two expresions equel each other

8x - 15 = 3x + 45

8x -3x - 15 = 3x - 3x + 45

5x - 15 = 45

5x - 15 + 15 = 45 + 15

5x = 60

5x/5 = 60/5

x = 12

Answer:

8x-15=3x+45 alternate angle

8x-3x=45+15

5x=60

x=60/5=12
