1: Divide the number of minutes by 60. 

2: 1 pints = 16 fluid ounces. 
You have 8 pints. 8 * 16 = 128

3: 2 gallons are in 8 quarts.

4: Because when you divide 25 by 8 the number is greater than 3.

5: By divide 6,400 by 2,000.

6: 4 gallons.

7: 1,280 ounces.

I have no idea about questions 8 and 9. I am sorry.

Hope this helps you! (:

Hello!

1. To convert minutes to hours, we must multiply the number of minutes by 60, because that is how many minutes there are in an hour.

2. 1 pint = 16 ounces

16 × 8 = 128

Fernando bought 128 fluid ounces of milk.

3. 1 quart = 0.25 gallons

0.25 × 8 = 2

2 gallons are equivalent to 8 quarts.


4. Because when you divide 25 by 8, the result is greater than 3.

5. By dividing 6,400 by 2,000, because that is how you will find the exact equivalent of 6,400 pounds in tons.

7. 1 pound = 16 ounces

16 × 80 = 1,280

1,280 ounces is equivalent to 80 pounds.

9.

The missing value in the table is 918, because:

1 yard = 3 feet

3 × 306 = 918

306 yards = 918 feet

<1 and <2 are supplementary
erik [133]

Answer:

x = 41

Step-by-step explanation:

\because \angle 1 \:\&\: \angle 2 \: are \: supplementary\\\therefore \angle 1 + \angle 2= 180°\\\therefore 3x°+ (2x-25)°= 180°\\\therefore 5x°-25°= 180°\\\therefore 5x°= 180°+ 25°\\\therefore 5x°= 205°\\\therefore x = \frac{205}{5}\\\huge \purple{\boxed {\therefore x = 41}}

Which expressions is equivalent to 6x^2-19x-55
ipn [44]
6x^2 - 19x - 55 = 6x^2 -30x + 11x - 55 = 6x(x - 5) + 11(x - 5) = (6x + 11)(x - 5)

PLEASE HURRY write the equation of the inverse function y=1/2cos^-1(pix)-3
GaryK [48]

Answer:

f^{-1}(x) = \frac{cos(2x+6)}{\pi }

Step-by-step explanation:

y = \frac{1}{2} cos^{-1} (\pi x)-3

Firstly, we've to interchange the variables.

x = \frac{1}{2} cos^{-1}(\pi y)-3

Solving for y

x = \frac{cos^{-1} \pi y}{2} -3

Adding 3 to both sides

x+3 = \frac{cos^{-1}(\pi y)}{2}

Multiplying 2 to both sides

2(x+3) = cos^{-1} (\pi y)\\2x+6 = cos^{-1} (\pi y)

Taking cosine on both sides

\pi y = cos (2x+6)

Dividing both sides by y

y = \frac{cos(2x+6)}{\pi }

Replace y by f^{-1}(x)

=> f^{-1}(x) = \frac{cos(2x+6)}{\pi }
