Help please I will really love that

Vsevolod [243]

If there's only 1 table, then you need 5 roses total (5*1 = 5)

If there are 2 tables, then you need 10 roses total (5*2 = 10)

If there are 3 tables, then you need 15 roses total (5*3 = 15)

If there are 4 tables, then you need 20 roses total (5*4 = 20)

At this point, you probably see the pattern: you multiply 5 by the number of tables to get the total number of roses. So it would look like this equation

(number of roses) = 5*(number of tables)

r = 5*x

where r is standing in for "number of roses" as shorthand; also, x is standing in for "number of tables".

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

Final Answer: r = 5x (lower right corner choice)

Note that 5*x is the same as 5x (both of which mean "5 times x)

How do u solve radius

kotykmax [81]

Answer:

To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π.

The two formulas that are useful for finding the radius of a circle are C=2*pi*r and A=pi*r^2.

The diameter is 2 times larger than the radius

Amanda earned a score of 940 on a national achievement test that was normally distributed. The mean test score was 850 with a st

algol [13]

harmaenderp AmbitiousFirst, to find out the number of students who scored below Amanda, we must find the z-score value of Amanda's score using the formula below.

where Z is the z-score, Χ is the expected average value, μ is the mean of Χ, and δ is the standard deviation. Thus, we have

Thus, using the z-table, we have P(Z<0.90) = 0.8159. Since we have wanted to find the number of students who scored below Amanda, then from the whole, we have (1 - 0.8159) = 0.1841. That means, out of 1000 students, 0.1841 of them scored below Amanda. Thus, we have (0.184)(1000) = 184.

Answer: 184 students

Suppose that the total profit in hundreds of dollars from selling x items is given by P(x) =4x2 - 5x + 10. Find the marginal pro

qaws [65]

The marginal profit is the profit that an individual or firm earns from producing and selling an additional item

The marginal profit at x = 5 is $3,500

The reason the above value is correct is as follows:

The given total profit function is P(x) = 4·x² - 5·x + 10

Where;

P(x) = The total profit in hundreds of dollars

x = The number items sold

The marginal profit is given by the derivative of the profit function

$Marginal \ profit = \dfrac{dP}{dx} = \dfrac{dR}{dx} - \dfrac{dC}{dx}$

Where;

P = Profit, R = Revenue, and C = Cost

Therefore, we have;

$Marginal \ profit = \dfrac{d}{dx} \left (4 \cdot x^2 - 5 \cdot x + 10\right) = 8 \cdot x - 5$

Marginal profit in hundreds of dollars = 8·x - 5

Therefore, the marginal profit at x = 5, is given as follows;

Marginal profit = 8 × 5 - 5 = 35

The marginal profit at x = 5 is $3,500
