Gnom [1K]

Answer:

Rasheed bought 3 packages of chocolate and 5 packages of toffee.

Step-by-step explanation:

In this case we have to found the number of bars that multiplied by the fractions presented give us an integer number and meets with the fact that the bars are an odd number because the packages came in packs of two bars.

For the case of the chocolate we have to find a number that meets this characteristics, we try with the number 6:

$6*\frac{2}{3} =4$

For chocolate Rasheed bought 3 packages, we can see that 6 bars meet the asked.

For the case of toffee, we try with number 10:

$10*\frac{3}{5} =6$

For toffee Rasheed bought 5 packages, we can see that 10 bars meet the asked.

kaheart [24]

Answer:

<em>A stack of 4 trillion one dollar bills will be $4\times 10^8$ meters.</em>

Step-by-step explanation:

The annual expenditure of the US federal government is approximately 4 trillion dollars.

We know, 1 trillion dollars = 10¹² dollars.

So, 4 trillion dollars $=(4\times 10^1^2)$ dollars.

Each one dollar bill is 0.0001 meters thick.

So, the total height of the stack of 4 trillion one dollar bills will be.....

$[0.0001\times(4\times 10^1^2)]meters\\ \\ =[10^-^4\times(4\times 10^1^2)]meters\\ \\ =(4\times 10^8) meters$

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

Oduvanchick [21]

Remember that $(g-f)(x)$ is $g(x)-f(x)$ . We know form our problem that $f(x)=4-x^2$ and $g(x)=6x$ , so:
$(g-f)(x)=g(x)-f(x)$
$(g-f)(x)=6x-(4-x^2)$
$(g-f)(x)=6x-4+x^2$

Now, to find $(g-f)(3)$ , we just need to evaluate $(g-f)(x)$ at 3. In other words, we are going to replace $x$ with 3:
$(g-f)(x)=6x-4+x^2$
$(g-f)(x)=6(3)-4+(3)^2$

We can conclude that the correct answer is <span>C.6(3) – 4 + 3^2 </span>
