3/5(20/20)= 60/100

1/4(25/25)= 25/100

60/100-25/100= 35/100

35/100 divided by 5/5= 7/20

The answers is 7/20.

Hope this helps!

Answer: The input variable is the number of days since September 9th.. The unit for the input variable is single days.

When you are given an equation, there is an input and an output. In this case, you put in the number of days and the output is the distance between the lava and the road.

If you make a chart of the inputs and outputs, you will see that the lava is getting closer to the road.

What is the distance between the two end points (5,6) (-4,-7) round to the nearth two decimal places

garri49 [273]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have:

$(5,\ 6)\to x_1=5,\ y_1=6\\(-4,\ -7)\to x_2=-4,\ y_2=-7$

substitute:

$d=\sqrt{(-4-5)^2+(-7-6)^2}=\sqrt{(-9)^2+(-13)^2}=\sqrt{81+169}=\sqrt{250}\\\\=\sqrt{25\cdot10}=\sqrt{25}\cdot\sqrt{10}=5\sqrt{10}$

Divide. (6.496×10−6)÷(2.8×105) Express your answer in scientific notation. Enter your answer in the boxes.

ss7ja [257]

we have been asked to perform $(6.496*10^{-6})\div (2.8*10^5)$

The given expression can be written as

$\frac{(6.496*10^{-6})}{2.8*10^5}$

Now it can be re-written as below

$=\frac {(6.496*10^{-6})}{2.8*10^5}=\frac{6.496}{2.8}*\frac{10^{-6}}{10^5}\\ \\ \text{Now using the exponent rule } \\ \\ \frac{a^m}{a^n}=a^{m-n}\\ \\ \text{we can re-write as below}\\ \\ \frac{6.496}{2.8}*\frac{10^{-6}}{10^5}= \frac{6.496}{2.8}*10^{-6-5}= \frac{6.496}{2.8}*10^{-11}\\ \\ \text{Now divide we get}\\ \\ =2.32*10^{-11}$
