Nicholas has a collection of books. He has 115 fantasy and science fiction books. These books are 46% of his collection. How man

Anit [1.1K]

Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.

Now we have to find what is total number of books in his collection.

Let number of books in Nicholas collection = x

then number of fantasy and science fiction books = 46% of x = 0.46x

We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:

0.46x=115

now we can solve this equation to find the answer.

$x=\frac{115}{0.46}$

x= 250

Hence final answer is:

Nicholas has 250 books in his collection.

Flying fish use their pectoral fins like airplane wings to glide through the air. Suppose a flying fish reaches a maximum height

GrogVix [38]

The flight is in the shape of a parabola with a vertex 5 feet above the water and 1/2 * 33 = 16.5 feet horizontally from the point of leaving the water

y = a(x - h)^2 + k

where (h,k) is the vertex of the parabola and here it is (5 , 16.5), so we have the function:-

y = a(x - 16.5)^2 + 5

when x = 0 y = 0 so

0 = a(-16.5)^2 + 5

which gives a = -0.018365

So our function for the flight path is

y = -0.018365(x - 16.5)^2 + 5 Answer

Graph the solution to this inequality on the number line.

Svetach [21]

Given the inequality expression:

w−0.8>−2.4

Inequalities are expressions separated by an unequal sign.

According to the given question, we need to find the solution for "w"

w−0.8>−2.4

Add 0.8 to both sides

w−0.8+0.8>−2.4 + 0.8

w > -2.4 + 0.8

Simplify the result by adding to have:

w > -1.6

Find the number line representing the solution attached;

If jimmy has 15 cookies and has 3 friends and wants to share how will he do it

8090 [49]

Answer:

If he includes himself then:

Split up the cookies into 4 equal parts.

$\frac{15}{4} = 3.75$

3.75 cookies each if he includes himself.

If he does not include himself:

Split up the cookies into 3 equal parts

$\frac{15}{3} = 5$

5 cookies each if he shares to his friends without including himself.
