She regrouped the numbers instead of multiplying like 8b(2b-r) -4r(2b-r).

She did not distribute the negative. Poor Clara.

What is the value of the expression? 1 1/3 x 2/7

natka813 [3]

Answer:

$\frac{2}{21}$

Step-by-step explanation:

First, apply the fraction rule.

$\frac{1}{3}\cdot \frac{2}{7}=\frac{1\cdot \:2}{3\cdot \:7}$

$=\frac{1\cdot \:2}{3\cdot \:7}\\$

Then, I multiplied the numbers on top.

$=\frac{2}{3\cdot \:7}$

Finally, I multipiled the numbers on the bottom.

$=\frac{2}{21}$

Hope this helps, and have a blessed day!

A team of storm enthusiasts collected data to show the relationship between the time between seeing lightning and then hearing t

never [62]

Answer:

Proportionality constant = $\frac{1}{5}$

Step-by-step explanation:

From the graph attached,

Data set representing the relation between seeing lightning and the hearing thunder is,

{(15, 3), (25, 5), (35, 7), (45, 9)}

Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)

d = kt

Here k = proportionality constant

k = $\frac{d}{t}$

From the data set one point is (15, 3).

k = $\frac{3}{15}$

k = $\frac{1}{5}$ miles per second

Therefore, proportionality constant is $\frac{1}{5}$ miles per second.
