Since it says only write a expression, you can do 45xM= ?/?
The answer is b.
Because you multiply (5•12)
Answer:
B. 2800 sq mm
Step-by-step explanation:
Given the following data;
Length = 80 mm
Width = 70 mm
Area of rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
Area of rectangle = 80 * 70
Area of rectangle = 5600 mm²
Since the paper (area of rectangle) was halved, we would divide by 2;
Area of each half = 5600/2
Area of each half = 2800 sq mm.
You find the least common multiple of the two denominators, then you multiply whatever you multiplied to the denominator to the numerator to get to the LCM.
ex:
3/4 + 2/3 --> 9/12+ 8/12= 17/12
Since we know in a standard deviation that mean plus 1 SD is 533 (66%) and 2 SD is 566 (95%) and 570 is slightly more than 566. Then the amount of race horses weighing within 570 is 98.3%. So to find those more than the mean would be 100%-98.3% which is 1.7%
