For all positive integers x ,what is the greatest common factor of the numbers 256x and 144x

1 answer:

4 0

First, let's factor both of these numbers.

256x:

$2^{8} * x$

144x:

$3^{2} * 2^{4} * x$

Both of these numbers contain $2^{4} * x$ , so that would be the greatest common factor. This could also be written as 16x.

David hikes 2 ¼ miles in ½ an hour at this rate, how long will it take him to walk 18 miles?

8090 [49]

So in 30 min will hike 2 1/4 miles =9 of those 1/4 miles therefore in 10 min will hike 9/3 =3 of those 1/4 miles = 3/4 of a mile

3/4 mile in 10 min;
(3/4)• 4 = 3 miles in 40 min;
6 miles in 80 min;
9 miles in 120 min;
12 miles in 160 min;
15 miles in 200 min;
18 miles in 240 min or 4 hours

Willis tower in Chicago is 1450 feet tall. The John Hancock Center in Chicago is 1127 feet tall. Suppose you are asked to build

gayaneshka [121]

Answer:

Small Scale replica of John Hancock tower is approximately 2.33 m.

Step-by-step explanation:

Given:

Height of Willis tower = 1450 ft

Height of John Hancock Center = 1127 ft

Small Scale replica of Willis tower = 3 m

We need to find Small Scale replica of John Hancock tower.

First we will find the per meter scale of Willis tower and then using the same we will use to find the Small Scale replica height of John Hancock tower.

For 3 meter scaling = 1450 ft

So for 1 meter scaling = Number of foots in 1 meter Scaling

By Using Unitary method we get;

Number of foots in 1 meter Scaling = $\frac{1450}{3} = 483.333 \ ft$

Now we had 1 meter scaling as 483.333 ft and we need to find meter scaling for 1127.

So again Using Unitary method we get;

Small Scale replica of John Hancock = $\frac{1127}{483.333} = 2.331 \ m$

Rounding to nearest hundred we get;

Small Scale replica of John Hancock tower is approximately 2.33 m.
