What is 0.123 rounded to the nearest hundredth
Sholpan [36]
You would round to 0.12, What you would do is look at the placement of each number. The 1 is in the tenths place, the 2 is in the hundreds and the 3 is in the thousands. So you look at the three and see if you would round up or down, if it is 5 or greater you round up if it is 4 or less then round down. This is less so you would round down to 0.12

What is the value of x?<br><br><br><br> Enter your answer in the box.<br> x =
lukranit [14]

Answer:

x = 24

Step-by-step explanation:

To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.

\frac{44.8}{x+4}=\frac{56}{35}

To solve for x, cross multiply:

44.8(35) = (x+4)(56)

1568 = 56x + 224

1344 = 56x

24 = x
