Answer:

<em>37%</em>

Step-by-step explanation:

Add up the percentages and subtract them by 1.00:

35% & 28% = 0.35 & 0.28
0.35 + 0.28 = 0.63
1.00 - 0.63 = 0.37
0.37 = 37%

Good luck! :)

Evaluate 150+n if n=15

IgorLugansk [536]

Answer: 165

Step-by-step explanation: To evaluate this expression, we simply plug the value of the variable into the expression and solve.

So here, since <em>n</em> is equal to 15, we have 150 + (15) which simplifies to 165.

Why is it helpful to write numbers in different ways

Goshia [24]

You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.

Writing one in many different ways:

1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)

=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)

=(1/4)+(1/4)+(1/4)+(1/4)

Writing a half in many different ways:

1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)

=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)

=2/4=3/6=4/8=5/10=0.5=0.50

etc...etc...

Find a counterexample to show that the conjecture is false. The product of two positive numbers is always greater than either nu

jekas [21]

Answer:

$\frac{1}{2}$ × $\frac{1}{4}$ = $\frac{1}{8}$

Step-by-step explanation:

This sentence isn't always true.

here is a counter example :

The trick is to use fractional numbers .

$\frac{1}{2}$ × $\frac{1}{4}$ = $\frac{1}{8}$

let's analyse this example :

$\frac{1}{2}$ $\geq$ $\frac{1}{8}$ and $\frac{1}{4}$ $\geq$ $\frac{1}{8}$

1/2=0.5 and 1/4=0.25 but 1/8=0.125

0.125<0.25<0.5

here is another example : (1/2)*(1/3)=1/6
the same thing : 1/6<1/3<1/2

Find the average rate of change of the exponential equation from x = 3 to x = 6

umka2103 [35]

The average rate of change of the exponential equation from x = 3 to x = 6 is 4.55

<h3>How to determine the average rate of change?</h3>

The function is given as:

$f(x) = 2x^{1.35$

When x = 3, we have:

$f(3) = 2 * 3^{1.35} =8.813$

When x = 6, we have:

$f(6) = 2 * 6^{1.35} =22.466$

The average rate of change is then calculated as:

$m = \frac{f(6) -f(3)}{6 - 3}$

This gives

$m = \frac{22.466 -8.813}{6 - 3}$

Evaluate

m = 4.55

Hence, the average rate of change of the exponential equation from x = 3 to x = 6 is 4.55
