How do I solve 2x³a³ over 5x⁻³a² multiplied by 5x⁻⁴a over 3x²a⁻⁵ ?

Answers

Answer 1
Answer: (2x^3a^3)/(5x^(-3)a^2)\cdot(5x^(-4)a)/(3x^2a^(-5))=(2x^(3-4)a^(3+1))/(3x^(-3+2)a^(2-5))=(2x^(-1)a^4)/(3x^(-1)a^(-3))=(2)/(3)a^(4-(-3))=(2)/(3)a^7

If a thermometer indicates 30 degrees Celsius, what is the temperature in degrees Fahrenheit? A. 54°F
B. 17°F
C. 24°F
D. 86°F

Answers


To calculate the Fahrenheit temperature:

-- Take the Celsius temp.
-- Multiply by 1.8 .
-- Then add 32 to the product.

   30°C  ==>  (30 x 1.8) = 54  ==>  54 + 32  =  86°F.
_____________________________________

To calculate the Celsius temperature:

-- Take the Fahrenheit temp.
-- Subtract 32 .
-- Multiply what's left by  0.55... (5/9 to be exact).

     86°F   ==>  (86 - 32) = 54   ==>  (54) x (5/9) =  30°C .
 

Answer:86F

Step-by-step explanation:

The domain of the following relation: R: {(−4, 8), (8, 10), (5, 4), (1, 6), (5, −9)} is{8, 10, 4, 6, −9}

{−4, 1, 5, 8}

{−4, 8, 5, 1, 5}

No domain exists

The correct answer would be B. When we find the range or domain we only list repeating values once.

Answers

Answer:  B) $1.75

===================================================

Explanation:

To get the unit cost, we divide the total cost over the number of pounds.

We can do this for any row

  • row one: ($17.50)/(10) = $1.75
  • row two: ($35.00)/(20) = $1.75
  • row three: ($52.50)/(30) = $1.75
  • row four: ($70.00)/(40) = $1.75

You don't need to show all four row calculations. You can simply pick one row.

This tells us that each pound costs $1.75

Put another way: the price is $1.75 per pound

What is the value of x in the equation 2x+7=1

Answers

2x + 7 = 1

Subtract 7 on both sides

2x = 1 - 7

2x = -6

Divide both sides by 2

x = -6/2

x = -3

Your answer is \boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\bf{x=-3}}}}}}}}}}}}}}}}}}}

2x+7=1 =>2x=1-7 => 2x=-6 => x= -6\2 => x=-3

the ratio of apples to oranges on the fruit stand was 31:11 if there were 2,940 apples and oranges altogether, how many apples are there

Answers

First you add 31 and 11 and you get 42, then you do 2,940 divided by 42 which is 70. Then you multiply 70 by 31, and you get 2, 170, 
and there are 2,170 apples which is the answer
