Answer:

52%

Step-by-step explanation:

First, find the difference between this year's sales and the previous'. 1500-990=510.

Now we can divide 990 by 510 to find the percent increase. 510/990=0.515151515152, or 52%.

Plzzzz help me with one and two I don’t understand
Ratling [72]
What this question simply asks about is you write the numbers it gave you in only one digit by 10 to the power of n. Where n represents the number of shifts of the decimal point.
And to get this number to be one digit, then you have to approximate.
To approximate; you should always consider that less than 5 counts zero and 5 or more counts+1.
Example:
5.3 is approximately 5
5.5 is approx. 6
5.9 is also approx. 6
and so on.
So the final answers are;
1) 4*10^13
2) 5*10^-11
Please note that 10^positive integer will cause the decimal point to move to the right which means a number greater than 1, usually, while 10^negative integer means number smaller than 1, usually.
Hope this helps.

What is the x-intercept of the graph?
Umnica [9.8K]

Answer: (6,0)

Step-by-step explanation: To find the x-intercept, we plug a 0 in for y.

So we have 2x - 3(0) = 12.

Simplifying from here, we have 2x = 12.

Now divide both sides by 2 and we get <em>x = 6</em>.

So our x-intercept is 6.

This means that our line crosses the x-axis 6

units to the right of the origin or at the point (6,0).

Select the equivalent expression.
Vanyuwa [196]

For this case we must find an expression equivalent to:(y ^ 3 * 2 ^ 5) ^ 2

By definition of power properties we have to meet:

(a ^ n) ^ m = a ^ {n * m}

So, rewriting the expression we have:

y^{3 * 2} * 2^ {5 * 2} =\\y^ 6 * 2^{10}

Answer:

Option B

y^6*2^{10}
