john currently has enough money to buy 45 books. If the cost of each book was 10 cents less.john could buy 5 more books. How muc

SVEN [57.7K]

Let the cost of one book= x cents
Let the money john have= y cents

According to the question,

45x=y ...eq(1)
(45+5)(x-5)=y
50(x-5)=y
50x-250=y ...eq(2)

On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50

Thus, cost of each book is 50 cents and john has 2250 cents.

Hope it helps.
Don't feel shy in saying thx if it helps.

What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?

olchik [2.2K]

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

Cylinder has a 5 centimeters height

Diameter of the cylinder is 1.5 centimeters

Step:1

Formula for the surface area of cylinder is,

$A=2\pi r h + 2\pi r^{2}$ ......................................(1)

Where,

h - Height of cylinder

r - Radius of cylinder

From the values of h and r,

$r=\frac{d}{2}$

= $\frac{1.5}{2}$

r = 0.75 cm

From the formula,

= ( 2 × $\pi$ × 0.75 × 5 ) + ( 2 × $\pi$ × $0.75^{2}$ )

= ( 7.5 $\pi$ ) + ( 1.125 $\pi$ )

A = 8.625 $\pi$ $cm^{2}$

Result:

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.

A coordinate plane with a line passing through the points (negative 4, negative 5) and (1, negative 1).

Ksju [112]

Answer:

4x - 5y - 9 = 0

$\frac{9}{4}$

$\frac{-9}{5}$

Step-by-step explanation:

The equation of a straight line passing through the points (-4,-5) and (1,-1) is given by $\frac{y - (-5)}{-5-(-1)} =\frac{x-(-4)}{-4-1}$

⇒ $\frac{y+5}{-4} =\frac{x+4}{-5}$

⇒ 5y + 25 = 4x + 16

⇒ 4x - 5y - 9 = 0 ....(1) (Answer)

Now, this above equation can be represented as

$\frac{x}{\frac{9}{4} } + \frac{y}{\frac{-9}{5} } =1$

Therefore, the x-intercept is $\frac{9}{4}$ (Answer)

And the y-intercept is $\frac{-9}{5}$ . (Answer)
