A camel can drink 15 gallons of water in 10 minutes. at this rate, how much water can the camel drink in 77 minutes?

gladu [14]

To solve this problem, we simply have to use ratio and proportion.

We know that 15 gallons is consumed in 10 minutes therefore the conversion factor is:

15 gallons / 10 minutes

Therefore in 77 minutes:

water consumed = (15 gallons / 10 minutes) * 77 minutes

<span>water consumed = 115.5 gallons</span>

Lincy is standing 20 feet from the circular wall of an above ground swimming pool and 49 feet from a point of tangency. Find the

BaLLatris [955]

Answer:

the radius of the pool is 50.025 feet

Step-by-step explanation:

From the information given:

We can have a schematic view of a diagrammatic illustration in our mind where the distance of the pool to Lincy is (20 + r ) and the distance to the tangent is 49.

So; by using pythagoras theorem, since the radius meets the tangent at a right angle; we have:

$r^2 + 49^2 = ( r + 20 )^2$

$r^2 +2401 = r^2 + 40r + 400$

$2401 = 40r + 400$

$2401- 400 = 40r$

2001 = 40 r

r = 2001/40

r = 50.025 feet

The area of a rectangle is 70 in 2 and the length of the rectangle is 3 in. Longer than the width

Snezhnost [94]

Alright, lets get started.

I hope, the dimensions of rectange are asked in this question.

Suppose the width of rectangle = x in

Given that length of the rectangle is 3 in longer than the width.

It means length of the rectangle = (x+3) in

Now, the area of the rectangle = lenght * width

area of the rectangle = $x * (x+3)$

area of the rectangle = $x^2+3x$

The area of a rectangle is 70 in square (given in question)

Equalling both areas

$x^2 + 3x = 70$

Subtracting 70 in both sides

$x^2 + 3x - 70 = 70 - 70$

$x^2 + 3x - 70 = 0$

Factoring

$(x-7)(x+10) = 0$

It will give two values of x

x = -10 (which is not possible because length could not be negative)

x = 7

Means width $= 7 in$

length $= 7 + 3 = 10 in$

Means the dimensions of rectangle are 7 in and 10 in. : Answer

Hope it will help :)
