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:

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

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.

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.

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: $95450

Step-by-step explanation:

We obviously want to look in the 3rd column.

Income that can be taxed is within interval for 33%, so (0.33)(315000) = $103950.

Subtract the tax credit, and we get $103950 - $8500 = $95450.

Answer:

Titanoba can grow up to 50 feet long.

Step-by-step explanation:

The value of the z score form the normal distribution table will be 1.96, 2.58, 0.91, and 0.0014.

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.

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)
