Explain how to use the unit rate to make a table

xxTIMURxx [149]

Answer:

to make a unit rate using a table you would take an input/output from a table and convert it into a fraction. Then you would take that fraction and simplify it. Sometimes you might have to choose a new input/output in order to make the simplification easier.

Example-

2:4

4:8

6:12

8:16

Turn one into a fraction

4/8

Simplify

1/2

Se arrastra un bloque de 18 kg a través de una superficie con una fuerza de 300 N en donde el coeficiente de fricción de dicha s

ozzi

Answer:

$10.9\ \text{m/s}^2$

Step-by-step explanation:

m = Masa del bloque = 18 kg

F = Fuerza en el bloque = 300 N

$\mu$ = Coeficiente de fricción = 0.6

El equilibrio de fuerzas del sistema viene dado por

$F-f=ma\\\Rightarrow 300-0.6\times 18\times 9.81=18a\\\Rightarrow a=\dfrac{300-0.6\times 18\times 9.81}{18}\\\Rightarrow a=10.9\ \text{m/s}^2$

La aceleración del bloque es $10.9\ \text{m/s}^2$ .

Solve the following system<br> 6x-3y=15<br> x+3y=-8

pentagon [3]

<h2>Answer:</h2>

This system can be solved for x by elimination.

$6x - 3y = 15\\ x + 3y = -8\\\\7x = 7\\\\x = 1$

Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.

$1 + 3y = -8\\\\3y = -9\\\\y = -3$

Now, we have our solution.

$(1, -3)$
