Mr. Nguyen plants 24 trees around the neighborhood pond. he plants equal numbers of maple,pine,spruce, and birch trees. ge water

Goryan [66]

Since he has 24 trees and 4 kinds of trees you divide them and get 6 that means there 6 trees in one kind so he already watered 2 kinds of trees and so you have 2 kinds of trees left so you do 6 × 2 = 12

Mrs. Miller has only $42.50 to spend at walmart. She buys a shirt that costs $29, including tax. She wants to buy some bracelets

pshichka [43]

Answer: 2

Step-by-step explanation: 42.50 is the max she can spend there’s .08 cent per dollar. $29 dollars for the shirt plus tax it’ll be 31.32 now Mrs.Miller is left with 11.18 out of her 42.50. Divide 11.18 by 4.50 because that’s the cost of each bracelet. 4.50 multiplied by 2 equals 9 plus tax it’ll be 9.72. 11.18 she had left minuse the 9.72 she’s left with 1.46

I need help with rational and irrational numbers here is the question.

4vir4ik [10]

Answer:

The correct answer choices are:

1) It is a real number

2) It is an irrational number

Step-by-step explanation:

So we have the number:

$\sqrt2$

First, let's define each of the terms:

Real numbers are all of the irrational and rational numbers. If a number is irrational or rational, then they are a real number. Any number that does not include the imaginary number i is real (you'll learn this eventually. It's actually really interesting!).

Irrational numbers are the numbers that do not terminate nor repeat. Examples include π or √3. Note that numbers like 1/3 which is .3333 is <em>not </em>irrational because they are repeating. π, on the other hand, does not repeat and never ends.

Rational numbers are the numbers that terminate or repeat. They also include the integers, whole numbers, and natural numbers.

So, the √2. First, it's real because it doesn't deal with imaginaries.

Next, use a calculator and calculate √2. We can see that it is about 1.41423562... This number does not repeat. And it does not terminate (end). In other words, √2 is a irrational numbers.

Since it is irrational, it cannot be rational. Since it's not rational, it cannot be an integer, whole number, or a natural number.

Therefore, the correct answer choices are:

1) It is a real number

2) It is an irrational number

A square technology chip has an area of 25 square centimeters how long is each side of the chip

grigory [225]

ANSWER

Each side of the chip is 5 centimeters long.

<u>EXPLANATION</u>

The chip is in the form of a square.

The formula for finding the area of a square is

$Area=l^2$

We were given in the question that, the area is 25 square centimeters. This means that,

$25=l^2$

We take the square root of both sides to get,

$\sqrt{25}=l$

$\Rightarrow 5=l$

Hence the length of the square technology chip is 5 centimeters

1. A boat drifted 15 m out into the water off Ocean Beach, where the shore drops off

Lunna [17]

The correct responses found using trigonometric ratios are as follows;

Brooke's cannot bring the boat back without getting water over her boots.
The plan will not be approved
The plane will not disturb
The company can not use the chimney legally
The Long company will build the bridge
The fireman can reach her.
The lift does not take the skiers up to the bar.
Eric will be able to see his Dad's plane.
The 73 m. brace

<h3>How can trigonometric ratios be used to find the right responses?</h3>

1. The depth of the water = 15 × tan(4°) = 1.049 m

The height of Brooke's boot = 1 m

Therefore;

Brooke's cannot bring the boat back without getting water over her boots.

2. The angle of elevation of the plan = arccos(99/100) ≈ 8.110°

Given that the angle of elevation the plan, 8.110°, is more than 8° limit, we find;

The plan will not be approved.

3. Height reached by the plane = 9 × tan(21°) = 3.455

Therefore;

The plane will not disturb.

4. Height of the chimney at the factory = 50 × tan(51°) = 61.745

The minimum chimney height = 65 m.

Therefore;

The company can not use the chimney legally.

6. Length of the bridge = 72 × tan(55°) ≈ 102.83

Therefore;

The Long company will build the bridge because it is longer than 100 m. but not more than 103 m.

7. Height reached by the ladder = 26 × sin(43°) ≈ 17.7

Therefore;

The fireman can reach her.

8. Height reached by the ski lift = 1000 × sin(29°) ≈ 484.8

Therefore;

The lift does not take the skiers up to the bar.

9. Height reached by plane = 26 × tan(9°) ≈ 4.12

The plane flies under the cloud therefore;

Eric will be able to see his Dad's plane.

10. Length required for the metal brace = 21/(cos(73°)) ≈ 71.83

Therefore;

The brace that wastes less metal is the 73 m. brace, because the 71 m. brace is not long enough and two braces will be required.
