1 answer:

8 0

$\frac{3}{4} ( \frac{1}{2} x-12)+ \frac{4}{5} =$

$=\frac{3}{4} ( \frac{x}{2} -12)+ \frac{4}{5}$

$= \frac{3x}{8} -9+ \frac{4}{5}$

$= -\frac{41}{5} + \frac{3x}{8}$

The answer is: $-\frac{41}{5} + \frac{3x}{8}$

Answer:

The answer to your question is: third option is correct

Step-by-step explanation:

Data

F (5, -1)

directrix y = 1

Then, after getting the graph, the vertix = (5, 0)

and p = 1

Formula

(x - h) ² = -4p(y - k)

(x - 5)² = -4(1)(y - 0)

(x - 5)² = -4y

y = (x - 5)² / -4

An item normally $15.99 is listed as being on sale for 30% off its original price, what must you pay?

KengaRu [80]

Answer: a. You must pay $11.19 for the item.

b.The price you would expect to pay would be $36.59

Step-by-step explanation:

Hi, for first the question you need to calculate the 30 percent of the price of the item, and then subtract that result to the original price.

So: $15.99 × 0,30 = $4.797

$15.99 - $4.797 = $11.19

You must pay $11.19 for the item.

Question 2:

It´s a similar resolution, first you calculate the 40 percent of the retail price, and then subtract that result to the retail price.

So:

$60.99 × 0,40= $24.396

$60.99 - $24.396 = $36.59

The price you would expect to pay would be $36.59

Answer:

water

Step-by-step explanation:

Comparison of numbers can be done a couple of different ways. One way is to subtract one from the other. If the difference is positive, the minuend (first number) is the larger of the two.

Another way is to divide one number by the other. If the ratio is more than 1, then the numerator is the larger number.

For numbers in scientific notation, the division is perhaps the easiest. Here, that gives you ...

$\displaystyle\frac{\text{water mass}}{\text{oxygen mass}}=\frac{2.99\times10^{-26}\text{ kg}}{2.66\times10^{-26}\text{ kg}}=\frac{2.99}{2.66}\approx 1.12$

This value is greater than 1, so the mass of a water molecule is greater.

You will note that the multipliers (10^-26 kg) cancelled because they were equal. If they are unequal, the usual rules of exponents apply.
