3+(4×12) words matching expression

Effectus [21]

Answer: 9

Step-by-step explanation:

circle formula pi x (rsquared)

R =5 (for all circles)

to find area of all circles multiply the area of one circle by 2. Do this because there are 2 circles on the yard, one whole circle and two half circles, making two circles.

so pi times 25=157.08 (roughly the number is rounded up because the decimal does not end)

now subtract this area from the total area of the rectangle to find the remaining area, which we will fill with wood chips. so 200-157.08=42.92 (using the exact decimal value on my calculator for all calculations, I am rounding them in the explanation.) So now we divide this by 5 because a bag of wood chips covers 5 square feet. 42.92/5=8.58, which we round up to 9, so we need 9 bags of wood chips as our answer.

Good Luck

Suppose that you invest $10,000 in a risky investment. at the end of the first year, the investment has decreased by 50% of its

natita [175]

well, let's take a looksie, if it decreased by 50% the 1st year, that means what's leftover is 50% of it, well

$\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{50\% of 10000}}{\left( \cfrac{50}{100} \right)10000}\implies 5000$

so, on the next year it increases by 60% of 5000

$\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{60\% of 5000}}{\left( \cfrac{60}{100} \right)5000}\implies 3000~\hfill \underset{current~value}{\stackrel{5000~~ + ~~3000}{8000}}$

well, 10% of 10000 is 1000 bucks, if the consultant is correct, I should have 10000 + 1000 = 11000, but I don't, so he needs a nice cup of tea and chill some.

well, I started with 10000 bucks, now I only have 8000, lost 2000 bucks, 2000 is 1/5 of 10000 or namely 20%.

Let U be the set of all books, N the set of all novels, and H be the set of all hardcover books. Describe, in words, the followi

Mice21 [21]

Given:

U be the set of all books, N the set of all novels, and H be the set of all hardcover books.

To find:

The description for the sets $N\cap H$ and $H'$ in words.

Solution:

We have,

U = The set of all books

N = The set of all novels

H = The set of all hardcover books.

We know that $N\cap H$ means common elements of set N and set H.

Therefore, $N\cap H$ is set of all books that are both novels and hardcover books.

We know that $H'$ is the set of elements of universal set except the elements of set H.

Therefore, $H'$ is the set of all books that are not hardcover books.
