Answer:

D


Step-by-step explanation:

Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.

Note: rate=\frac{Distance}{Time}


(A)

rate = \frac{300}{4}=75 mph (miles per hour)

(B)

rate = \frac{450}{6}=75 mph

(C)

rate = \frac{750}{10}=75 mph

(D)

rate = \frac{800}{12}=66\frac{2}{3} mph


<u>As we can see, the first 3 rates are same, 75 mph, and the last one is 66\frac{2}{3} mph. So clearly, the last rate is the slowest.</u>

D is the right answer.

Could you help me with this. <br><br> Express in simplest radical form.<br> 162<br><br> ​
Ivanshal [37]

Answer:

The square root of 162 in its simplest form means to get the number 162 inside the radical √ as low as possible.

Here is how to do that! First we write the square root of 162 like this:

√162

The largest perfect square of the factors of 162 is 81. We can therefore convert √162 like this:

√81 × 2

Next, we separate the numbers inside the √ as such:

√81 × √2

√81 is a perfect square that equals 9. We can therefore put 9 outside the radical and get the final answer to square root of 162 in simplest radical form as follows:

9√2

The difference between two numbers is 9 and the product of the numbers is 162. Find the two numbers
fiasKO [112]
Let the no be X and Y

acc to ques....

x-y=9 .........1

xy=162 ..........2

substituting value from 1 in 2 we get;

x=9+y

[9+y][y] = 162

y^2+9y = 162

y^2 + 9y - 162=0

y^2 + 18y - 9y - 162=0

y[y+18] + 9[y+18]=0

[y+9][y+18}

y= -9.................................3


y= -18......................................4



case 1 :

y= -9

x = 9-9=0

case 2:

y= -18

x= 9-18 = -9
