In 2004, there were 19,396 bulldogs registered by the American Kennel Club. Approximately 86% of this number were registered in

ss7ja [257]

To solve this problem you must find 86% of 19,396.
To do this, let's start by turning 86% a decimal to multiply.
86% will become 0.86
Now, we multiply 0.86 by 19,396.
We get the answer, 16680.56
The question says about, so we need to round it.
When rounded we get 16681.
That means 16681 bulldogs were registered in 2003.
Hope this helped you! :)

A motorboat travels 172 km in 3 hours going upstream and 372 in 4 hours going downstream. What is the rate of the boat in still

torisob [31]

Answer:

The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h

Step-by-step explanation:

System of Equations

Let's call:

B = speed (rate) of the boat in still water

S = speed (rate) of the stream

The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:

$\displaystyle B-S=\frac{172}{3}$

Multiplying by 3:

3B - 3S = 172 [1]

The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:

$\displaystyle B+S=\frac{372}{4}=93$

B + S = 93

Solving for B:

B = 93 - S [2]

Substituting in [1]

3(93 - S) - 3S = 172

Operating:

279 - 3S - 3S = 172

279 - 6S = 172

Subtracting 279:

- 6S = 172 - 279

- 6S = -107

Multiplying by -1 and solving for S:

$S = \frac{107}{6}\approx 17.83\ km/h$

From [2]:

$B = 93 - \frac{107}{6}$

$B=\frac{451}{6}\approx 75.17\ km/h$

What will be the overall fee and how to set up the equation. F(x) = 2x + 5

maxonik [38]

For whatever they give you for x, you substitute that with the 2(x)+5
Ex. if the x was 3 it would be 2(3)+ 5 and then the answer would be 11 since 3 times 2 is 6 and then 6+5=11
