Going against the current, a boat takes 6 hours to make a 120-mile trip. When the boat travels with the current on the return tr

ip, it takes 5 hours. If x = the rate of the boat in still water and y = the rate of the current, write an expression that represents the rate of the boat going with the current. Type the expression in the space provided. Type only lowercase letters and do not use spaces in your answer

Answer:

120 miles/6 hours = 20 mph. You need to do the same for the boat going with the current. 120 miles/ 5 hours = 24 mph.

Gnom [1K]

Kriste respone is wrong

<em><u>Solution:</u></em>

Given that,

Kristen was asked to write each of the numbers in the expression 80,000 x 25 using exponents

Her response was (8 x 10 to the power of 3) x 5 to the power of 2

No, the response of Kristen is wrong

Let us first understand about exponents

An exponent refers to the number of times a number is multiplied by itself

Given expression is:

80000 \times 25

Here, 80000 has 4 zeros

Therefore, it can be raised as 10 power 4

80000 = 8 \times 10^4

<em><u>Thus the expression becomes:</u></em>

80000 \times 25 = 8 \times 10^4 \times 25

Also, 25 can be written as 5 power 2

80000 \times 25 = 8 \times 10^4 \times 5^2

Thus given expression is written as (8 x 10 to the power 4) x 5 power to the power 2

Thus Kristen respone is wrong, because he has raised 10 to power 3

bija089 [108]
Here is how you find the number of possible U.S Zip codes. 
<span>Take note of this: There are 10 1 digit numbers: 0,1,2,3,4,5,6,7,8,9.
</span>And we have 5 slots. So in each slot, there can be 10 possible numbers. 
So let's put 10 in each blank slot. 
10, 10, 10, 10, 10.
Therefore, the final answer would be 100,000. There are 100,000 possibilities of different U.S zip codes. Hope this answer helps.

PLS HELP:( !! What is an equation of the line
pychu [463]

Answer:

y =  \frac{3}{2} x + 8

Step-by-step explanation:

The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).

Thus, gradient of given equation= -⅔

The products of the gradient of perpendicular lines is -1.

(Gradient of line)(-⅔)= -1

Gradient of line

=  - 1  \div ( -  \frac{2}{3} ) \\  =  \frac{3}{2}

Hence, m= \frac{3}{2}.

Subst. m= \frac{3}{2}into the equation:

y =  \frac{3}{2} x + c

To find the value of c, substitute a pair of coordinates into the equation:

When x= -4, y= 2,

2 =  \frac{3}{2} ( - 4) + c \\ 2 =  - 6 + c \\ c = 2 + 6 \\ c = 8

Thus, the equation of the line is y =  \frac{3}{2} x + 8.
