Round off 53.96 to the nearest tenth​
Ne4ueva [31]

Answer:

54.0

Step-by-step explanation:

53.96

The bold number is in the tenth form and needs rounding off. So look at the number after the bold number (6).

Now 6 falls off the 5 or greater category, meaning that you have to add one to the bold number.

9 + 1 = 10

Now since the number is 10, you add the number before the bold number by 1 (underlined number) and replace the bold number by 0.

5<u>3</u>.96

54.00

Since you are focusing on the tenth place, keep the zero sitting on that spot.

54.0

9 cm and the other leg measures 11 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
nasty-shy [4]

Answer:

14.2 cm

Step-by-step explanation:

The hypotenuse of a triangle is measured using the pythagorean theorem. This formula sums up the squares of both legs of the triangle which would give the squared value of the hypotenuse. Therefore, we can then square root that value to find the hypotenuse. This would be the following...

9^{2} + 11^{2} = x^{2}

81 + 121 = x^{2}

202 = x^{2}

14.21 = x^{2}

Finally, we can see that the value of the hypotenuse is 14.2 cm
