xxMikexx [17]

Supplementay means adds to 180
x and y could be 100 and 80
x and y could be 1 and 179

acute means that it is less than 90

since we are not told what x or y is, y could or could not be acute

Two numbers have a average of 17. If one of the numbers is 11, what is the other number

Len [333]

Answer:

Other number is 23

Step-by-step explanation:

Let the two numbers be x and y.

We have given that average of x and y is 17.

i.e $\frac{x+y}{2} = 17$

if one of the number is 11,

Then , $\frac{11+y}{2} = 17$

or (11 + y)/2 = 17

or 11 + y = 34

or y = 34 - 11

or y = 23

What is the sum of 4/10 , 37/100 and 12/100?

Travka [436]

Answer: $\frac{89}{100}$

Step-by-step explanation:

$\frac4{10} + \frac{37}{100} + \frac{12}{100}$ They have to have the same denominators so we will multiply 10 by 10 to get to a hundred since the two fractions have the same denominator

$\frac{4}{10}$ * $\frac{10}{10}$ = $\frac{40}{100}$

Now add them

$\frac{40}{100} + \frac{37}{100} + \frac{12}{100}$ = $\frac{89}{100}$
