Answer:
$ 22.98
Step-by-step explanation:
discounted = 5%
sold at = 100 % - 5%
= 95%
let the original price of CD be x
= 95% of x =21.84
= 95/100 × x = 21.84
= x = 21.84 × 100/95
= x = 2184/95
= x = $22.98Please mark my answer the brainliest and rate me 5 star and follow me.please please please please please please
y-1/4x=-1
y-2=4x
one solution, no solution or infinite solution?
Answer:
One solution
Step-by-step explanation:
To start, let's simplify the equations to slope-intercept form
y - 1/4x = =1
+1/4x +1/4x
y = 1/4x - 1
y - 2 = 4x
+2 +2
y = 4x + 2
As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.

If a carton contains 6 eggs, how many eggs are there in 13 cartons?
Answer: 78 eggs
Step-by-step explanation:
We can set up a ratio.
Let x be the amount of eggs in 13 cartons.
Then, [tex]\frac{1 carton}{6 eggs} = \frac{13 cartons}{x eggs}[/tex]
Now we can cross multiply and we get x = 78 eggs
The total number of eggs in the 13 cartons is 78.
What is the total number of eggs in the 13 cartons?Given the parameters:
Number of eggs in one carton = 6 eggs
Number of cartons = 13
Total number of eggs in 13 cartons =?
To determine the total number of eggs in 13 cartons, you simply multiply the number of eggs per carton (6) by the number of cartons (13).
Using the multiplication method:
Total number of eggs = Number of eggs in one carton × Number of cartons
Plug in the values:
Total number of eggs = 6 eggs/carton × 13 cartons
Total number of eggs = 6 eggs × 13
Total number of eggs = 78 eggs
Therefore, the total number of eggs is 78.

Answer:
324pi
Step-by-step explanation:
V of sphere = 4/3 x pi x r^3
V of cone = pi x r^2 x h x 1/3
4/3 x pi x 6^3 = 288 pi
pi x 6^2 x 15 x 1/3 = 180 pi
since the sphere is cut in half = 288/2 = 144
144 pi + 180 pi = 324 pi
Assume Z has a standard normal distribution. Use Appendix Table III to determine the value for z that solves each of the following:
(a) .
Enter your answer in accordance to the item a) of the question statement
(Round the answer to 2 decimal places.)
(b) .
Enter your answer in accordance to the item b) of the question statement
(Round the answer to 2 decimal places.)
(c) .
Enter your answer in accordance to the item c) of the question statement
(Round the answer to 2 decimal places.)
(d) .
Enter your answer in accordance to the item d) of the question statement
(Round the answer to 1 decimal place.)
The value of the z score form the normal distribution table will be 1.96, 2.58, 0.91, and 0.0014.
What is a normal distribution?It should be noted that a normal distribution simply means a probability distribution which is symmetric about the mean.
From the complete question, value of the z score form the normal distribution table will be calculated thus:
P(-z < Z < z) = 0.95
1 - P(Z < - z) - P(Z > z) = 0.95
1 - P(Z > z) - P(Z > z) = 0.95
1 - 2 × P(Z > z) = 0.95
P(Z > z) = (1 - 0.95)/2 = 0.025
This will be 1.96 from the normal probability table.
For P(-z < Z < z) = 0.99
1 - P(Z < - z) - P(Z > z) = 0.99
1 - P(Z > z) - P(Z > z) = 0.99
1 - 2 × P(Z > z) = 0.99
P(Z > z) = (1 - 0.99)/2 = 0.005
This will be 2.58 from the normal probability table.
For P(-z < Z < z) = 0.64
1 - P(Z < - z) - P(Z > z) = 0.64
1 - P(Z > z) - P(Z > z) = 0.64
1 - 2 × P(Z > z) = 0.64
P(Z > z) = (1 - 0.64)/2 = 0.18
This will be 0.91 from the normal probability table.
For P(-z < Z < z) = 0.9973
1 - P(Z < - z) - P(Z > z) = 0.9973
1 - P(Z > z) - P(Z > z) = 0.9973
1 - 2 × P(Z > z) = 0.9973
P(Z > z) = (1 - 0.9973)/2 = 0.0014
This will be 2.99 from the normal probability table.
Therefore, the correct options are 1.96, 2.58, 0.91, and 0.0014.

Discuss each of the following descriptions. How precise is the information they supply? (A) The sweatshirt comes in small,
medium, or large. (B) The dress is a size 14. (C) The engagement ring is a size 6.
Answer:
Step-by-step explanation:
An engagement ring is likely very precise. The ring sizes used by some jewelers differs from the next size by 0.8 mm. As a % that's .8 / 16.5 * 100 = 4.80 %
The 0.8 is the number of mm needed to go from a size 6 to a size 7 ring size. So if you are ever going to buy a ring, be sure and let a jeweler measure the finger that it will go on.
The 16.5 mm is the diameter of the ring in mm. for a size 6 ring. If you have different information, you should go with what you have,
Size 14 dress
I can't answer this: it depends on where you live -- Europe or the US.
Also the type of dress matters: is it a skirt or a skirt and blouse combination. The % of the sides is much larger than 4% for the ring but it is still a definite description.
Small Medium or Large
Depends entirely on where the garment is made, and where it is being sold.
Wish tells you to add a size if you live in North America. This too is not very distinct.

What is the missing length?
8 mi
1)) area
=
56 mi?
Answer:
7 mi
explanation:
area of rectangle = length * width
given:
Length: 8 miWidth; vusing the formula:
length * width = area
8 * v = 56
v = 56/8
v = 7
Answer:
v = 7 mi
Step-by-step explanation:
Formula:
Area of a rectangle = width x length
Given:
area = 56 mi²width = 8 milength = vInputting given information in the formula:
⇒ 56 = 8v
Divide both sides by 8:
⇒ 7 = v
Solution:
Therefore, the missing length v is 7 mi

Answer:
3(2v - 3)(3v + 2)
Step-by-step explanation:
18v² - 15v - 18 ← factor out 3 from each term
= 3(6v² - 5v - 6) ← factor the quadratic
consider the factors of the product of the coefficient of the v² term and the constant term which sum to give the coefficient of the v- term.
product = 6 × - 6 = - 36 and sum = - 5
the factors are - 9 and + 4
use these factors to split the v- term
6v² - 9v + 4v - 6 ( factor the first/second and third/fourth terms )
= 3v(2v - 3) + 2(2v - 3) ← factor out (2v - 3) from each term
= (2v - 3)(3v + 2)
Then
18v² - 15v - 18 = 3(2v - 3)(3v + 2)

Mr. Easmon drew triangle JKL, with a height of 18 inches and a base of 18 inches, and triangle XYZ, with a height of 16 inches and a base of 20 inches. Which triangle has the greater area.
Answer:
Triangle JKL
Step-by-step explanation:
The formula to find the area of a triangle is :area (A) = (height (H) x base (B)) / 2
You are given the height and base of both triangles, so you just have to plug in the numbers.
Triangles JKL: A = (18 x 18) / 2
A = 162 in^2
Triangel XYZ: A = (16 x 20) / 2
A = 160 in^2
162 is greater than 160, so Triangle JKL has a larger area.
Answer:ABC has greater area
Step-by-step explanation:
ABC:
Formula for a triangle is base * height divided by two so:
6*6/2 = 18

The hawk moth is the fastest flying insect. It can fly up to 33.3 miles per hour. A hornet can fly up to 13.3 miles per hour. About how much faster can the moth fly than the hornet?
Answer:
"The maximum speeds we found were approaching, you know, approximately 100 kilometers an hour; they can go incredibly fast," says Chapman. That means millions of moths fly together at about 60 miles an hour. That's faster than many birds migrate.
