Explain why using either compatible numbers or rounding as a method for estimation would be the same for 32×695?

1 answer:

5 0

The question here is why using either compatible numbers or rounding as a method for estimation would be the same?
Well, we use rounding as a method of estimation to get a solution in a certain equation faster yet the same.
For example, in the given equation we have 32 x 695
=> Instead of 32, we can use 30
=> instead of 695, we can use 700
=> 30 x 700
=> the answer is 21 000
Now, let’s multiply the exact number
=> 32 * 695
=> 22 240
Not, really exact yet close.
That’s how estimation works.

Options

(0, 35)

(10, 30)

(15, 25)

(20, 15)

Answer:

Step-by-step explanation:

The profit p in dollars of selling x widgets and y gadgets is given by the function p(x,y)=7x+6y.

Option A

When x=0 and y=35

p(x,y)=7(0)+6(35)

p(x,y)=210

Option B

When x=10 and y=30

p(x,y)=7(10)+6(30)

p(x,y)=250

Option C

When x=15 and y=25

p(x,y)=7(15)+6(25)

p(x,y)=$255

Option D

When x=20 and y=15

p(x,y)=7(20)+6(15)

p(x,y)=$230

We observe that the point (15, 25) in Option C yields the highest profit ($255). Therefore, it is the point that maximizes profit.

Although not so common now, consider a phone plan that does not have unlimited texting. Your base plan costs you $30 a month and

Answer:

$y=.12x+30$

Step-by-step explanation:

The total cost would be "Y".

"x" is would be "per text message".

12 cents per text message would be .12x.

And then, on top of that, we have to pay $30 per month. ( + 30 )

Put together, the equation should be y = .12x + 30.

So hmmm check the graph below

now.. to find the vertex of any quadratic

$\bf \textit{vertex of a parabola}\\ \quad \\

\begin{array}{lccclll}
h(t)=&-16t^2&+16t&+480\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

so... how long did it take? well, it took $\bf -\cfrac{{{ b}}}{2{{ a}}}$

what was the highest point? well, it was $\bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}$

when did he hit the water? well, at y = 0
that is $h(t) = -16t^2 + 16t + 480 \implies 0 = -16t^2 + 16t + 480,$

solve for "t"
