Answer:

The volume is 1120 units³.

Step-by-step explanation:

The volume of a prism is the multiplication of the cross sectional area by its length.

Therefore, find the area of the triangle, and then multiply it by the length:

$v = ( \frac{8 \times 14}{2} )(20) = \\ = (4 \times 14)(20) = \\ = 56(20) = \\ = 1120$

Of the 60 animals on a certain farm, 2/3 are either pigs or cows. How many of the animals are cows? (1) The farm has more than t

mario62 [17]

Answer:

Step-by-step explanation:

$\frac{2}{3}of total=$ either cow or pigs

$\frac{2}{3}of 60=$

$\frac{2}{3} X 60=40$

Either pigs or cow = 40

(1) Let number of pigs be x

then number of cows >twice of pigs = 2x

number of pigs + number of cows = 40

number of cows = 40 -x

40-x > 2x

40 > 3x

x < $\frac{40}{3}$

x < 12.33

nearest integral number is 12

so its 12

so number of pigs will be 12 so that number of cows = 40 -12 = 28

which is more than twice of number of pigs

28 > 2( 12) = 24

(2) number of pigs + number of cows = 40

for x>12

number of cows = 40 -x

x > 12

-x < -12

adding 40 both sides

40-x < 40-12

number of cows <28

An amount of $600 is shared among three people in the ratio 1 : 2 : 3 , find the difference between the smallest and the largest

Oxana [17]

Answer:

200

Step-by-step explanation:

Total amount to be distributed is $600.

Ratio of distribution is 1:2:3

Let the smallest share be x

Then the other shares will be 2x and 3x as per the ratio of distribution.

But sum of all shares is 600.

$=> x+2x+3x=600$

$=> 6x=600$

$=> x=\frac{600}{6}$

$=> x=100$

So the respective shares are 100,200 and 300.

Difference between the largest and smallest share is $300-100 = 200$

When we’re writing, we can use a thesaurus to find a different word with the same meaning to present an idea. How can we find di

Pavlova-9 [17]

Answer:

Math has the particularity that it is a logical construction.

This means that we can start with an expression X (where X is an equation, not a variable)

Now we can apply a lot of "math" to this equation in such a way that we can rewrite it, but the actual "meaning" of the equation will not change.

An example of this is factoring.

For example, we can write a quadratic equation as:

a*x^2 + b*x + c.

And we also can write this as:

n*(x - k)*(x - j)

where k and j are the solutions of the equation:

a*x^2 + b*x + c = 0.

What is the advantage of writing the equation in each form?

Well, both expressions actually represent the same thing, but the explicit information in each expression is different, so depending on what we want to do, we will choose one option or the other.

And we have lot's of different ways to express something, where we can find some ones really complex and useful, like the series of Taylor, where we can write a function as a summation of infinite terms.
