48 m

Since area of the square having measure48m is in between the given range

Step-by-step explanation:

Area of square if side length is 46=2116 m²

Area of square if side length is 44=1936 m²

Area of square if side length is 48=2304 m²

Area of square if side length is 50 = 2500m²

Answer:

48!

Step-by-step explanation:

If the plot of land is a square, then the area can be found by multiplying one side by another. You'll have to multiply each number by itslef to see if the answer ranges anywhere between 2200 and 2400. 48 x 48 = 2304. 2304 is a number in between 2200 and 2400, and it is the only answer that is between 2200 and 2400. So, 48 can be one of the possible side lenghths of that square plot of land.

Will give brainliest to right answer please help!! 15 points -A sample of a radioactive isotope had an initial mass of 370 mg

Alex777 [14]

Answer:

78 mg

Step-by-step explanation:

370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)

260 mg ÷ 8 years = 32.5 mg decayed per year

32.5 × 9 years (years between 2008 and 2017) = 292.5 mg

370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg

Alicia is writing the program for a video game. For one part of the game, she uses the rule

astra-53 [7]

As the mapping suggests, the first (x) coordinate is decreased by 3, and the second (y) coordinate is increased by 2. So, given the inputs, you have

$(-2,0) \mapsto (-2-3, 0+2) = (-5,2)$

$(3,-4) \mapsto (3-3, -4+2) = (0,-2)$

And yes, this rule is a function: it has a starting set (the domain), which is all possible couples $(x,y)$ , and a landing set (the codomain), which is again composed by the couples $(x,y)$ . Since for every point in the domain you have one and only one output, this rule is a function.
