List four rational numbers between -1 and 0

Answers

Answer:

4 rational numbers between -1 and 0 are;

(-¼, -½, ¼, ⅜)

Step-by-step explanation:

Rational numbers between two numbers say x and y is given by;

(x + y)/2

Thus;

Rational number between -1 and 0 = (-1 + 0)/2 = -1/2

Rational number between 0 and -1/2 = (-½ + 0)/2 = - 1/4

Rational number between 1 and -1/2 = (-½ + 1)/2 = 1/4

Rational number between 1 and -1/4 = (-1/4 + 1)/2 = ⅜

Thus,4 rational numbers between -1 and 0 are;

(-¼, -½, ¼, ⅜)

3% for 30 years. Jack will not make any
| additional deposits or withdrawals. How
X much interest will he have earned at the end X
of the 30 years?
Round your answer to the closest dollar
amount.

Answers

Answer:

Step-by-step explanation:

I think this is the equation for annual compunt interest

FV = PV(1 + int)^time PV is present value FV is the future value

PV + Interest = FV

FV - PV = Interest

FV - PV

Interest = [3000(1 + 0.03)^30] - 3000

= 3000(1.03)^30 - 3000

= 3000(2.4272) - 3000

= 7281.79 - 3000

= $4282 to the nearest dollar <------------ Fianl Answer

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?

Answers

Answer:

To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.

volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140

Final Answer: 140 one foot by one foot containers can fit in Mr. Powell's storage space

(Show Work

Answers

Answer:

r = 46

Step-by-step explanation:

To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.

1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.

[tex]60 = 5r-4r + 14\\60 = r + 14[/tex]

2) Now, finally isolate r by subtracting both sides by 14.

[tex]60 = r + 14\\46 = r[/tex]

So, r = 46.

Nancy has a rectangular garden with length, I, width, w, and a perimeter of 28 feet The length of the rectangle is 2 less than 3 times the width. Choose the system of equations that can be solved to find land w

Answers

Answer:Perimeter =2l +2w

28=2(3x-2) + 2x

Width =4feet

Length =10feet

Step-by-step explanation:

Perimeter of rectangular garden =2(l+b)

Let the width be represented as X

And the length which is 3x-2

Such that the equation to solve for length and width be

Perimeter =2l +2w

28=2(3x-2) + 2x--- system of equation

Solving

28=2(3x-2) +2x

28=6x-4+2x

28=8x-4

28+4=8x

32=8x

X=32/8

X=4

Width =4

Length =3x-2=3x4-2=10

2. Fill in the book value at the end of year 1 under each depreciation method when residual value is $36,000 and useful life is 4 years: Depreciation method: Straight-line Units-of-Output

Answers

Answer:

$260,437.50

$108,750

Step-by-step explanation:

Here is the complete question :

Fill in the book value at the end of year 1 under each depreciation method when residual value is $36,000 and useful life is 4 years: Depreciation method:

Straight-line $335,250

Units-of-Output

Double-declining $217,500

Book value = cost of the asset - first year depreciation expense

Straight line depreciation expense = (Cost of asset - Salvage value) / useful life

(335250 - 36,000) / 2 = $74,812.50

Book value = $335,250 - $74,812.50 = $260,437.50

Depreciation expense using the double declining method = Depreciation factor x cost of the asset

Depreciation factor = 2 x (1/useful life) = 2/4 = 0.5

$217,500 x 0.5 = 108,750

Book value = $217,500 - 108,750 = $108750

Each gallon of paint covers $200$ square feet. I have to paint one side of a wall that is $12$ meters tall and $80$ meters long. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?

Answers

5 gallons of paint would be the least amount of paint you would need

The smallest whole number of gallons require to paint the wall is 52 gallons.

Given that, 1 gallon of paint = 200 ft², 1 foot = 0.3048 meters and dimension of wall is 12 meter by 80 meter.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Converting the dimension to feet :

12/0.3084 = 39.370078 feet

80/0.3084 = 262.46719 feet

Hence, the area of the wall is

Area = Length × width

Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²

Let number of gallons required = x

Since, 1 gallon = 200 ft²

x gallons = 10093.516 ft²

Cross multiply :

200x = 10093.516

x = 10333.35374274082/200

x = 51.6667687137041 gallons

x = 52 gallons

Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint.

Answer and Step-by-step explanation:

It depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.

A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.

Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?

The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
