Answer:

$\large\boxed{12.25=\dfrac{49}{4}}$

Step-by-step explanation:

$12.\underbrace{25}_{2}=\dfrac{1225}{1\underbrace{00}_2}=\dfrac{1225:25}{100:25}=\dfrac{49}{4}\\\\12.25=12+0.25=12+\dfrac{25}{100}=12+\dfrac{25:25}{100:25}=12+\dfrac{1}{4}\\\\=\dfrac{12\cdot4}{4}+\dfrac{1}{4}=\dfrac{48+1}{4}=\dfrac{49}{4}$

Step-by-step explanation:

Using Pythagoras Theorem,

The length of the other leg

$= \sqrt{ {19}^{2} - {12}^{2} }$

$= \sqrt{217}$

$= 14.730919...$

= 14.7 cm (rounded to the nearest tenth)

Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. clear check how many pounds of gravel does it take to cover one sq

timama [110]

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

From given question,

252 lb = 36 ft² ..........(1)

The number of pound for an area of 1 square foot is calculated as follows:

x = 1 ft² .......(2)

The area and the amount of gravel are illustrations of proportions.

From (1) and (2) we get an equation,

⇒ x × 36 = 252 × 1

⇒ x = 252/36

⇒ x = 7 lb

We need to find the area that could be covered with 315 lb of gravel

The area to be covered with 315 lb gravel is calculated as follows:

315 lb = y ............(3)

From (1) and (3) we get an equation,

⇒ y × 252 = 36 × 315

⇒ y = 45 ft²

Therefore, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The table shows the height of water in a pool as it is being filled. A table showing Height of Water in a Pool with two columns

icang [17]

Answer:

The height of the water increases 2 inches per minute.

Step-by-step explanation:

the slope is always the ratio of

y coordinate change / x coordinate change

in our case, x is the time (minutes), and y is the water height (inches).

we see, the longer the pool get filled, the higher the water gets. logical, right ?

by checking the data points we see :

with every 2 minutes passing the water height increases by 4 inches.

so, the slope is +4/+2 = 2/1 = 2

and that ratio tells us now the increase of the water height with every fraction or multiple of the measured 2-minute interval.

every 2 minutes 4 inches more.

so, e.g. every 3×2 = 6 minutes we get 3×4 = 12 inches more.

and - every 1/2 × 2 = 1 minute more we get 1/2 × 4 = 2 inches more.
