“. . . when in the wrought chest the wind blowing over and the sea heaving struck her [Danae] with fear, her cheeks not dry, she put her arm over Perseus and spoke: My child such trouble I have. And you sleep, your heart is placid; you dream in the joyless wood; in the night nailed in bronze, in the blue dark you lie still and shine. The salt water that towers above your head as the wave goes by you heed not, nor the wind’s voice; you press your bright face to the red blanket. If this danger were danger to you, your small ear would attend my words. But I tell you, Sleep, my baby, and let the sea sleep, let our trouble sleep . . .” —Simonides, Greek poet, as quoted in A Soaring Spirit: Time Frame 600–400 B.C.

1.Cesiah has a pencil box containing 4 green pencils, 6 blue pencils, and 10 red pencils. If she randomly selects a pencil from the bag, what is the probability, in decimal form, that she picks a green pencil?

Answers

Answer:

If you add up the amount of pencils there are then you get 20,

so that means that you have 20 pencils in all, and out of the 20 pencils, 4 of them are green so the probability is 4/20

and 4/20 in decimal form is 0.2, so the probability is unlikely that she will pick a green pencil

The owner of a resale shop is analyzing the revenue for the year. Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500?

Answers

Answer:

hope this helps with other things have a a good day

Step-by-step explanation:

The required number of items the owner must sell is 15 items so he can earn a $500 profit.  

Given that,
Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
500 = x² - 14x + 485
x² - 14x - 15 = 0
x² - 15x + x - 15 = 0
x (x - 15 ) + 1 (x - 15 ) = 0
(x - 1 ) (x - 15 ) = 0

Number of items he must sell to earn $500 profit,

x - 15 = 0
x = 15

Thus, the required number of items the owner must sell is 15 items so he can earn a $500 profit.

A circular fountain has a radius of 9.4 feet. Find its diameter and circumference to the nearest hundredth. ( Please help)

Answers

A circle is 360 and it has a radius then 9.4 you will get 40.7

Answer:

The diameter is 11.20 feet. The circumference is approximately 35.17 feet.

Step-by-step explanation:

Use the formula.

d = 2r The diameter of a circle is the same as 2 times the radius.

d = 2(5.6) The radius is 5.6. Substitute 5.6 for r.

d = 11.20 Multiply.

Use the formula.

C = πd

C = π(11.20) The diameter is 11.20. Substitute 11.20 for d.

C ≈ 3.14(11.20) Substitute 3.14 for π.

C ≈ 35.17 Multiply.

The diameter is 11.20 feet.

The circumference is approximately 35.17 feet.
