So imagine every straight line you see equals to 180 degrees, so given one side of the angle...180 - 108 = 72

Answer:

Step-by-step explanation:

Because as we know the angle of this is 180 and we already have (108°) so we have to add 108° to one of the numbers till we get to (180°)

Answers

Answer:

= 7.58 × 10-6

Answer:

7.58 x 10^-6

Step-by-step explanation:

Move the decimal 6 times to the right in the number so that the resulting number, m = 7.58, is greater than or equal to 1 but less than 10.

Since we moved the decimal to the right the exponent n is negative. n = -6.

Write in the scientific notation form, m × 10n = 7.58 × 10-6

Sometimes True:

The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.

For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.

Always True:

The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.

Always True:

The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.

Assume that the sum of an irrational number a and a rational number b is rational.

Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.

Sometimes True:

The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.

For example, √2 x 2 is irrational, but √2 x (1/√2) = 1 is rational.

For 1.999 × 2.4, how many decimal hops would you move (right to left) to place in your answer?

Answers

Answer: 4

Step-by-step explanation: it is 4 because there are a total of 4 different decimal places in the equation so if the equation was 1.2 times 1.2 you would decimal hop 2 times because there are to numbers behind the decimal

Answer:

1999 × 24 = 47976

In 1.999 the are 3 digits after the decimal. In 2.4 there is 1 digit after the decimal.

3 + 1 = 4

We move the decimal 4 places to the left or 1 place to the right of 47976.

Step-by-step explanation:

3x+2y=6 and y=1/3x-11 perpendicular or parallel

Answers

Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.

For two lines y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate k1 and k2.

To calculate the slope k of any line, you have to change the equation to y=kx+b

For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))

For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)

Now you can get the answer: The two lines neither parallel nor perpendicular.

As the puck is sliding across the ice at a relatively constant speed, it passes close to a player, who hits it (with his stick) in the same direction as it is already moving. After the hit, you notice that the puck is moving much faster than it was before the hit. Your classmates propose the following three explanations for why the puck is moving faster after the hit than before. Whose reasoning do you agree with?Student A: "The force of the stick was transferred to the puck during the hit. After the hit, the puck has more force, so it moves faster."Student B: "The puck still has the force that started it moving, which is what keeps it moving at a constant speed. When the player hit it, he adds to this force, which makes the speed of the puck increase. After the hit, this extra force is gone, so the puck stops increasing its speed, but the original force is still there so now it moves at a faster constant speed."Student C: "While the stick is in contact, it applies a force to the puck that makes its speed increase. As soon is contact is lost, this force disappears, so the speed of the puck stops increasing."
