Answer:

4a - 40 = 1

Step-by-step explanation:

4/5 a - 8 = 1/5

Brian read 8 1/4 pages of a book in 1/6 hour. At thus rate, what is the total number of pages if the book he will read in 1 hour
Oksana_A [137]
8 1/4 -> 1/6 hour
How many pages -> 1 hour?

You can use the cross multiply method
\frac{8 \ \:\frac{1}{4} \times 1 }{ \frac{1}{6} }


= 49.5 pages

Or you change the hours to minutes.
1/6 hour is 10 min.
[1/6 × 60 = 10 ]
Either way you'll get the same answer.

How are a desert and a tundra similar?
Hatshy [7]

Answer:

D is right option

Step-by-step explanation:

Similarities:

<em>Both the biomes experience less precipitation due to this they have a less diversity of flora and fauna as compared to other biomes like savanna, grasslands, chaparral etc. Let us see how they differ from each other!</em>

Low rain fall _ annual rainfal of lessthan 20cm in deserts, 15-20cm in tundra

Minimal life_ only small shurbs can survive in both kind of environments

Poor drainage.. In deserts, though sandy soil may seem much porous, these are most flood prone areas of world. The tundra is characterised by permafrost soils ie, under the thin layer of soil, a thick ice sheet is present and hence is no seepage.

High range of temperatures: In tundra, the maximum temperatures are recorded in summer (abt 10^C) and minimum during winter(-20 to -30^C). While, in desert too, the temperature range is high but diurnally ie, nights are too cold and day time is scorching.

Roxanne is planning to enclose her right triangular shaped garden with a fence. How many
sergiy2304 [10]

Answer:

The perimeter of Roxanne's right triangular garden is 79 feet.

Step-by-step explanation:

Given,

Length of 1 side = 19 feet

Hypotenuse = 33 feet

We have to find out the perimeter of the triangular garden.

Solution,

Since the garden is in shape of right triangle.

So we apply the Pythagoras theorem to find the third side.

"In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides".

So framing in equation form, we get;

33^2=19^2+(third\ side)^2\\\\1089=361+(third\ side)^2\\\\(third\ side)^2=1089-361\\\\(third\ side)^2=728

Now taking square root on both side, we get;

\sqrt{(third\ side)^2} =\sqrt{728} \\\\third\ side=26.98\approx27\ ft

Now we know that the perimeter is equal to sum of all the three side of a triangle.

Perimeter = 19+27+33=79\ ft

Hence The perimeter of Roxanne's right triangular garden is 79 feet.
