Answer:

70 mins

Step-by-step explanation:

This is called inverse proportion.

1hr : 14in

x hr : 12in

Ask yourself, what do you do to 14 to get 12? To find this out, we do:

14 / 12 = 1.16666667

Since the blade is smaller, it will take longer. So, we times 1hr by 1.16666667 to get

1.16666667 hrs =

1.17 hours (rounded)

This is 70.2 mins, or 1hr 10 mins

Hope this helps!

If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.

What is width?

The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.

How to calculate time?

We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:

It will be as 14/12* 1 hour

=14/12

=1.167

=1.17 hour

Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.

The ratio of the height to the width of a packaging label is 5 to 19. If the height of the label is 1.5 inches, What is the widt
zhuklara [117]

Answer

Find out the  what is the width .

To prove

Let us assume that x be the scalar multiple of the height and width of the packaging label .

As given

The ratio of the height to the width of a packaging label is 5 to 19.

If the height of the label is 1.5 inches .

Than the equation becomes

5x = 1.5

x = \frac{1.5}{5}

x = 0.3

Than

The width of a packaging label = 19 × 0.3

                                                    = $ 5.7

Therefore the width of the packaging label is $ 5.7 .

Given sets X, Y, Z, and U, find the set Xn(X - Y) using the listing method.
Aliun [14]

Answer:

{f, a}

Step-by-step explanation:

Given the sets:

X = {d, c, f, a}

Y = {d, e, c}

Z ={e, c, b, f, g}

U = {a, b, c, d, e, f, g}

To obtain the set X n (X - Y)

We first obtain :

(X - Y) :

The elements in X that are not in Y

(X - Y) = {f, a}

X n (X - Y) :

X = {d, c, f, a} intersection

(X - Y) = {f, a}

X n (X - Y) = elements in X and (X - Y)

X n (X - Y) = {f, a}
