frozen [14]

Answer:

The length is 35 inches and the width is 15 inches.

Step-by-step explanation:

First work of the real length of the field. Given is the ratio of drawing to original and the dimensions of the drawing. so in real life the lawn measures 70 inches in length and 30 inches in width.

Now, we have to divide this in the ratio 1:2, which gives

The length of 35 inches and the width of 15 inches.

Hope this helps

constructing a border around a pool a circular pool measures 10 feet across. one cubic yard of concrete is to be used to create

Paha777 [63]

Answer:

We get w = 1.508 feet.

Step-by-step explanation:

Let w be the width of the border.

The diameter of the pool will be 10 feet.

The depth will be 3 inches. So, we will convert it to feet.

3 inches = $\frac{3}{12}=0.25 feet$

The circular area including pool and the border, radius = $(w+5)$

Border area = Total area - pool area

= $\pi (w+5)^{2} -\pi (5)^{2}$

Putting pi = 3.14 and solving the expression we get the following equation:

$3.14w^{2}+31.4w-53.5$

As given one cubic yard of concrete is to be used, this is the volume to be used.

1 cubic yard = 27 cubic feet

Now using the volume given and thickness of this area that is 0.25 feet.

$0.25(3.14w^{2}+31.4w-53.5) =27$

$=> 0.785w^{2}+7.85w-13.375-27= 0$

$=> 0.785w^{2}+ 7.85w-13.625= 0$

Solving this quadratic equation, we get w = 1.508 feet and w = -11.508 feet.

Neglecting the negative value, we get w = 1.508 feet.

Jason's mom drove at 100 km/h for a

EastWind [94]

Answer: $0.17\ hours$ or $10\ minutes\ and\ 40\ seconds$

Step-by-step explanation:

For this exercise you must use the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is the distance and "t" is the time.

Solving for "t":

$t=\frac{d}{V}$

You know that Jason's mom drove a distance of $160\ km$ at $100\ \frac{km}{h}$ . Then, we can say that:

$V_1=100\ \frac{km}{h}\\\\d=160\ km$

Then, the time is:

$t_1=\frac{160\ km}{100\ \frac{km}{h}}\\\\t_1=\frac{8}{5}\ h$

If she had driven $90\ \frac{km}{h}$ :

$V_2=90\ \frac{km}{h}\\\\d=160\ km$

And the time would have been:

$t_2=\frac{160\ km}{90\ \frac{km}{h}}\\\\t_2=\frac{16}{9}\ h$ or

Subtracting those times, you get:

$\frac{16}{9}\ h-\frac{8}{5}\ h=0.17\ h$ or $10\ minutes\ and\ 40\ seconds$
