Answer 1

Answer:

a is greater than -2

Step-by-step explanation:

Solving a comparison like this is the same as solving an equation, except you need to watch out for the signs of numbers.

Given:

-2a - 12 < -8

The first thing we need to do here is to add 12 to both sides:

-2a - 12 + 12 < -8 + 12

-2a < 4

You'll notice we're just increasing both sides, so the relationship stays the same.

Now we divide both sides by -2.  Because the number is negative, it changes whether the result is greater or less.

-2a < 4

-2a ÷ -2 > 4 ÷ -2

a > -2

Giving us our final answer.

If a ball has a rebound ratio of 0, what does that mean?

Answers

Answer: The test is conducted with an electromagnetic or vacuum release mechanism which releases a soccer ball from a height of 2 meters. From that the height of the rebound is measured by recording the sound of the first and second bounce. The time between the first and second bounce is measured. Also During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. ... It reaches way higher than from the height it was released.

Calculate the side lengths a and b to two decimal places.

Answers

Answer:

Below in bold.

Step-by-step explanation:

m < C = 180 - 43 - 115 = 22 degrees.

Using the Sine Rule:

6 / sin 22 = a / sin 43

a sin 22 = 6 sin 43

a = 6 sin 43 / sin 22

a = 10.92 to 2 DP's.

Applying the same rule  to calculate b:

6 / sin 22 = b / sin 115

b = 6 sin 115 / sin 22

b = 14.52 to 2 DP's.

the sum of a number n and 3 is 9

Answers

Answer:

n is 6

Step-by-step explanation:

because sum means addition and if you subtract 9 by 3, you get 6, so we now know that the missing number is 6 because when you add 6 and 3, you get 9. :)

The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

The sum of a number n and 3 is 9. Then the equation is given below.

n + 3 = 9

Simplify the equation, then we have

n + 3 = 9

n = 9 - 3

n = 6

The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.
