Convert the mixed number into a fraction. To do this, multiply the denominator by the whole number, and add the numerator. 5*4+3=23. Then put that over the denominator.

So we now have 23/5 * 7. To multiply fractions, multiply the numerators together and the denominators together.

(23*7)/5 = 161/5 or 32.2

Find the length of the unknown side. Round your answer to the nearest tenth.

Paraphin [41]

Answer:

<em>The correct option is: 11.5</em>

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so <u>using Pythagorean theorem</u>, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

<em>(Rounded to the nearest tenth)</em>

So, the length of the unknown side is 11.5

Answer:

D is not a supported statement

Step-by-step explanation:

Let take them one by one:

A: from table: 0.57; in statement: 0.5

0.57 > 0.5 so this is supported

B: from table: 0.2+0.16=0.36; in statement: 1/3=0.33,

0.36>0.33 so this is supported

C: 0.07 is the least, so this is supported

D: the table DOES NOT show number of students, but proportions. So statement '7 students' IS NOT supported

E: from table 0.20 overslept. 0.2 < 1/4=0.25, so this is supported
