Answer:
1) 04.4750
Step-by-step explanation:
The most obvious reason would be that if you put in 3.58 x 1.25 into a calculator the answer u get is 4.4750.
If you want a more technical explanation though, you can say that the combined number of decimal places in the multiplicand and the multiplier is 4, so the product will also have 4 decimal places.
3.58 = two decimal places
1.24 = 2 decimal places
in total, they have 4 decimal places. for the product to have 4 decimal places too you'd count from right to left 4 places, and that's where you'd put the decimal. Hope this helps!
Answer:
x = 100
Step-by-step explanation:
The ratios of long side to hypotenuse are the same for all these triangles.
x/(x+10) = (x+10)/(x+21)
x^2 +21x = x^2 +20x +100 . . . . . multiply by (x+10)(x+21), expand
x = 100 . . . . . . . . . . . . . . . . subtract x^2 +20x
