Convert both percents into decimals. To do that, move the percent sign two places to the left then multiply.

50% => 0.50
150% => 1.50
1.50 * 0.50 * x ; Start
0.75 * x ; 1.50 * 0.50 is 0.75

The final answer is 0.75 * x. Which can also be expressed as 3/4x.

That’s the number is written in standard scientific notation?

Nata [24]

Option D: 3.47*10^-7 is the correct answer

Step-by-step explanation:

In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written

the scientific numbers are written in the form of:

$a*10^n$

Here

a is a number between 1 and 10 while the value of n can be only integer (positive or negative)

so,

In the given options:

Option A has a number larger than 10 in place of a so it is not in standard notation

Option B has a number less than 1 in place of a so it is also not in standard notation

Option C has a number larger than 10 in place of a so it is not in standard notation

Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer

Hence,

Option D: 3.47*10^-7 is the correct answer

6. Consider the polynomial p(x) = x^2 + kr^2 +x+6. Find a value of k so that x+1 is a factor of P. Find all the zeros of P.

Nikitich [7]

If x + 1 is a factor of p(x) = x³ + k x² + x + 6, then by the remainder theorem, we have

p (-1) = (-1)³ + k (-1)² + (-1) + 6 = 0 → k = -4

So we have

p(x) = x³ - 4x² + x + 6

Dividing p(x) by x + 1 (using whatever method you prefer) gives

p(x) / (x + 1) = x² - 5x + 6

Synthetic division, for instance, might go like this:

-1 | 1 -4 1 6

... | -1 5 -6

----------------------------

... | 1 -5 6 0

Next, we have

x² - 5x + 6 = (x - 3) (x - 2)

so that, in addition to x = -1, the other two zeros of p(x) are x = 3 and x = 2

Will a 9m long planks fit into a square room of side 7m? please I really needed help with this one

Darya [45]

No because if it is a square all the sides are 7m long so a 9m plank will not fit. Hope this helps.
