To figure out this equation, you need to add the two areas. So, 145,552 plus 82,144 equals 227,696 square miles total. Hope that helps! :)

Answer: 10

Step-by-step explanation: 15*2=30,

then you take 50 and subtract 30 from it that leaves you with 20

You then take that 20 and divide it by 2 (because there are two sides that have the width) you get 10

What is the value of this expression when a = 4, b = -5, and c = -7?

Ganezh [65]

Answer:

The value of the given expression is -878.08.

Step-by-step explanation:

Here, the given question is INCOMPLETE.

The complete question is:

Evaluate the expression for a = 4, b = -5, and c = -7. $4a^2b^{-2}c^3$

Here, substitute the vale of a = 4, b = -5 and c = -7, we get:

$4a^2b^{-2}c^3 = (\frac{4a^2c^3}{b^2}) = (\frac{4(4)^2(-7)^3}{(-5)^2})\\= (\frac{64 \times 343}{25}) =\frac{21,952}{25} = 878.08\\\implies 4a^2b^{-2}c^3 = 878.08 ( a = 4, b = -5 ,c = -7)$

Hence, the value of the given expression is -878.08.

it takes maya 30 minutes to solve 5 logic puzzles,and it takes amy 28 minutes to solve 4 logic puzzles, in minutes per puzzle

Harman [31]

Answer:

MAYA (6 minutes)

Amy (7 minutes)

Step-by-step explanation:

MAYA

Takes Maya 30 minutes to solve 5 Puzzle:

Let's express it as,

30 mins = 5 Puzzle

1 min = x Puzzle

Cross multiply to solve for the number of questions Maya solves in a minute.

It becomes:

30*x = 5*1

30x = 5

x = 30/5

x = 6mins.

It means it takes Maya 6 mins to solve one question.

FOR AMY

Takes Amy 28 mins to solve 4 puzzles.

Let's represent it as:

28 mins = 4 Puzzles

x min = 1 puzzle

Let's solve for x

(28 mins) * (1 puzzle) = 4 * x

28 = 4x

x = 28/4

x = 7 mins

It means, it takes Amy 7 minutes to solve 1 puzzle
