Cube of the sum of 4 and 9 times x means (4+9x)^3
Product of 5times x and the difference of x and 1 means 5x(x-1)

Lets divide

Expression is

$\\ \sf\longmapsto \dfrac{(4+9x)^3}{5x(x-1)}$

katovenus [111]

We have been given that a librarian noticed that 60% of seventh graders checked out fantasy books. We are asked to find the number of seventh graders from 240 seventh graders, who would checkout fantasy books.

To solve our given problem, we need to find 60% of 240.

$\text{Seventh graders, who would checkout fantasy books}=240\times \frac{60}{100}$

$\text{Seventh graders, who would checkout fantasy books}=240\times 0.60$

$\text{Seventh graders, who would checkout fantasy books}=144$

Therefore, 144 seventh graders would checkout fantasy books.

The softball team stopped for ice cream after a big game. five 2-scoop cones cost the same as three sundaes. If they bought nine

Savatey [412]

<span>Let the cost of 2-scoop cones be x, and the cost of sundaes be y.
The first statement tells us that 5x = 3y
The second statement tells us that 9x + 6y = 19.95
Then we need to calculate the value of y (the cost of a sundae).
From our first equation, y = 5x/3. Substituting this into the second equation:
9x + 6(5x/3) = 19.95
9x + 10x = 19.95
19x = 19.95
x = 1.05
Substituting back into the first equation: 5(1.05) = 3y
5.25 = 3y
y = 1.75
Therefore the cost of a sundae is $1.75.

Black bird starts his flight path from (2, 0). his flight path reaches a maximum height of 20 yards and lands at point (38, 0).

Salsk061 [2.6K]

The maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have:

The blackbird starts his flight path from (2, 0). His flight path reaches a maximum height of 20 yards and lands at point (38, 0).

Here the bird path will be a parabola with a maximum height of 20 yards.

The total horizontal distance traveled by the bird = The distance between the points (2, 0) and (38, 0)

= √(38-2)²

= 36 yards

Thus, the maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).

A number divided by 3 less then itself gives a quotient of 8/5. Find the number

Airida [17]

We Can Let "A Number" Be M.
M Divided By 3 Less Than Itself Gives Quotient Of 8/5.
M/(M-3) = 8/5. Lets Solve.

$\frac{M}{(M - 3)} = \frac{8}{5}$
So, What Number Can Have 3 Subtracted From It To Get Five, But Also Be Equal To Eight?
Eight Of Course!!!
So, We Know That The Number Equals 8.
