The area of a square piece of land is 784metersquared .What is the perimeter​
Marta_Voda [28]

Answer:

112 m

Step-by-step explanation:

The area (A) of a square is

A = s² ( s is the length of side )

Here A = 784 , then

s² = 784 ( take the square root of both sides )

s = \sqrt{784} = 28

Then

perimeter = 4s = 4 × 28 = 112 m

Please help me due today and i really need help brainliest goes to the person who answers correctly and first this is really har
Andrei [34K]
1). the submarine is descending 100 feet per minute. this is because the line decreases 100 on the y axis when the x axis increases by 1.
2). the submarine is descending 50 feet per minute. this is because the line decreases 50 on the y axis when the x axis increases by 1.
3). y=15x this is because the slope increases by 15 on the y axis when 1 is increased on the x axis. the y intercept is 0. this means that every hour of piano lessons they get paid $15.

I hope this helps, and hopefully I’m right :)

a farmer notes that in a field of goats and geese there are 41 heads and 114 feet how many of each animal are there
solniwko [45]

Answer:

There are 25 geese and 16 goats

Step-by-step explanation:

Let O represent the # of goats and E the # of geese.  Remembering that goats have four feet and geese only two, and that each animal has only one head, we can write the following equations to determine O and E:

Number of heads:  41; this is the total of the # of goat heads and the # of goose heads:  O + E = 41

(4 feet per goat)O + (2 feet per goose)E = 114 (There are a total of 114 feet)

Then we solve the following system of linear equations:

  O   +   E   =    41

 4O   +   2E  = 114

Multiplying the first equation by -2 results in -2O  - 2E  = -82.

Combining this result with the second equation, we obtain the system

 4O  +  2E  =  114

 -2O  - 2E  = -82

-------------------------------

  2O =   32

Then O = # of goats = 32/2, or 16, and so the equation O   +   E   =    41 becomes

         E  = # of geese =  41 - O (remembering that we found O to be 16), or

         E  =  41 - 16  = 25


There are 25 geese and 16 goats.
