Step-by-step explanation:

What is an improper fraction

A fraction is improper when its numerator is greater than its denominator. When a fraction is 'improper' it can be expressed as a whole number plus a proper fraction. A proper fraction is a fraction that has a numerator smaller than its denominator, a fraction that has a value less than 1.

The mixed numbers form shows the whole portion followed by the proper fraction.

Keller boat travels 24mph. find the rate of the river if she can travel 6 mi upstream. in the same amount of time she can go 10

nikitadnepr [17]

The correct answer is:

6 mph.

Explanation:

We will use the formula d = rt for this, where d is distance, r is rate, and t is time.

We know that the time for both distances is the same; this means we want to isolate t in our formula. To do this, we will cancel r by dividing both sides:
d/r = rt/r
d/r = t

We will write an expression for the time upstream, an expression for the time downstream, and set them equal.

For the time upstream, the distance is 6 and the rate is 24-x; this gives us

$\frac{6}{24-x}$

For the time downstream, the distance is 10 and the rate is 24+x; this gives us

$\frac{10}{24+x}$

Together, these give us the equation

$\frac{6}{24-x}=\frac{10}{24+x}$

We cross-multiply to solve this:
6(24+x) = 10(24-x)

Using the distributive property, we have
6*24 + 6*x = 10*24 - 10*x
144+6x = 240-10x

Adding 10x to each side,
144+6x+10x = 240-10x+10x
144+16x = 240

Subtract 144 from each side:
144+16x-144 = 240-144
16x = 96

Divide both sides by 16:
16x/16 = 96/16
x = 6

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.

Delvig [45]

Answer:

17650 in².

Step-by-step explanation:

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

$\bf\implies TSA_{(cylinder)}= 2\pi r ( r + h ) \\\\\bf\implies TSA_{(cylinder)}= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_{(cylinder)}= 2\times \dfrac{22}{7}\times 39 \times 72 \\\\\sf:\implies \boxed{\red{\bf TSA_{(cylinder)}= 17650 in^2}}$
