Step-by-step explanation:

106

The tens place is the 0, so we look at the ones place

Since 6 is 5 or greater we round the tens place up

0 will round to 1, and the ones places goes to 0

106 rounds to 110

We need a number less than 180 that will round up to 180 from the tens place

We look at the tens place, it has to be less than 8 by 1

17 x

The number must be 5 or greater to round the 7 up to 8

175, 176, 177, 178, 179 will work

We need a number greater than 180 that will round down to 180 from the tens place

We look at the tens place, it has to be equal to 8

18 x

The number must be 4 or less to leave the 8 alone

180, 181, 182, 183, 184

Find the weighted average of a data set where 20 has a weight of 3, 40 has a weight of 5, and 50 has a weight of 2.

Citrus2011 [14]

The weighted average of a data set is 36.

Here,

Given data set;

20 has a weight of 3, 40 has a weight of 5, and 50 has a weight of 2.

We have to find the weighted average of a data set.

What is Weighted Average?

Weighted average is a calculation that takes into account the varying degrees of importance of the numbers in a data set.

Now,

Given data set;

20 has a weight of 3, 40 has a weight of 5, and 50 has a weight of 2.

The weighted average is given by the formula;

$x = \frac{f_{1} x_{1} + f_{2} x_{2}+ f_{3} x_{3}+ ...... f_{n} x_{n}}{f_{1} +f_{2} + f_{2}}$

Hence,

The weighted average of a data set;

$x = \frac{20*3+40*5+50*2}{3 +5+ 2}$

$x = \frac{360}{10} = 36$

Hence, The weighted average of a data set is 36.

No because an acute triangle is less than 90 degrees and a right angle is 90 degrees so it doesn't work.

the perimeter of a rectangle is 192 ft. the ratio of its length to its width is 7:5 what are dimensions of the rectangle?

Jobisdone [24]

Answer: Hence the dimensions are 56 ft and 40 ft.

Step-by-step explanation:

Alright, lets get started.

The ratio of sides of rectangle is given as 7:5.

It means, the length of rectangle is : $7x$

It means, the width of rectangle is : $5x$

So the perimeter of rectangle will be : $2(length + width)$

Plugging the value of sides length and width,

the perimeter of rectangle will be : $2\times(7x+5x)$

the perimeter of rectangle will be : $2\times 12x$

the perimeter of rectangle will be : $24x$

As per question, the given perimeter is 192, so

$24x=192$

Dividing 24 in both sides,

$x=\frac{192}{24}$

$x=8$

Hence the length of rectangle will be : $7\times 8 =56$

Hence the width of rectangle will be : $5\times 8 =40$

Hence the dimensions are 56 ft and 40 ft. : Answer

Hope it will help :)
