Answers

Answer:

6

Step-by-step explanation:

-6×(-1)=6

When multiplying two negative numbers, the product will always be positive. When multiplying one negative number and one positive number, the product will always be negative.

So think of this equation as 6×1, since two negatives equal a positive.

The answer is 6 because a negative times a negative is a positive

Find the rate of change (slope) from the table below

Answers

1/2 is correct.

the slope is 3/6 which is equivalent to 1/2
The slope is equivalent to -1/2. Every time the left column adds one number, the right column subtracts two. You can test this by adding in filler numbers missing in between the table. For example, between 5 and 7 would be 6. If you were subtract 2 from 10 (the previous left column answer), you would get 8. Subtract 2 from there and you would get 6. You could also test this by graphing it and simply counting how many units you’re going up or down compared to how many units you’re going left or right. Hope this helps. Lmk if you have any questions!

A motorboat, that has speed of 10 km hour in still water, left a pier traveling against the current of the river. Forty-five minutes after the boat left the pier, the motor of the boat broke, and the boat began drifting with the current. After three hours of drifting with the current, the boat was back at the pier where it had started. What is the speed of the current of the river?

Answers

9514 1404 393

Answer:

  2 km/h

Step-by-step explanation:

  distance = speed × time

The boat's progress upriver can be modeled by ...

  (10 -c)(3/4) +(0 -c)(3) = 0

  7.5 -3.75c = 0 . . . . simplify

  2 -c = 0 . . . . . . . . . divide by 3.75

  c = 2 . . . . . . add c

The speed of the current is 2 km per hour.

Answers:
Wood Question: 860 millimeters
Heigh Question: 73 centimeters

Explanations:
Wood Question: You can get this result by doing 7.74/9 because you are dividing 7.74 meters into 9 pieces and you will get 0.86, AKA 86 centimeters. Then, you need to multiply that by 10 to convert it into millimeters and 86(10) is 860.

Height Question: First, you want to do 1.46/2 and you will get 0.73. 0.73 meters is equivalent to 73 centimeters, and since you know Jaxson is two times his sister's height, you know that you can leave it at that, therefore your final answer is 73 centimeters.

I suck at math so be nice n help:)

Answers

Answer: See explanation

Step-by-step explanation:

1. ∠WOV and m∠30° are complementary angles so they should add up to 90°

∠WOV + 30 = 90

Subtract 30 from both sides

∠WOV = 60°

I used the relationship of complementary angles.

2. ∠YOZ and ∠WOV are vertical angles so they're congruent.

∠YOZ ≅ ∠WOV

∠YOZ ≅ 60°

∠YOZ = 60°

I used the relationship of vertical angles.
