Polynomials are not always closed under which operation?

A)Addition
B)Subtraction
C)Multiplication
D)Division

Answers

Answer 1

Answer:

D

Step-by-step explanation:

Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

Then take 338.25 and add 5.50 and you should get 343.75

can anyone pls help im struggling with this

Answers

You have to add like terms.

7x and 6x are like terms. If you don’t do that, the answer will be wrong

If you add them, then it would be

13x + 18 = 4
Subtract 18 from each side
13x = -14
Divide both sides by 13 to get
X = -14 / 13
they subtracted 6x from 4. you can’t do that because 6x has a variable while 4 doesn’t. x = - 14/13

Emily wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with a length of 6m and a width of 2m. She decides on a scale of 1cm to 0.5m. If the kitchen door is 1.2m wide, how wide should the door be on the scale drawing? Be sure to include units

Answers

Answer:

2.4 cm

Step-by-step explanation:

The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)

She decides to draw 1cm for the original length of 0.5m=50 cm.

For this, the scaled dimension on the drawing=1cm and

the original dimention=50 cm

So, the scale-factor = 1/50.

As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.

So, the scaled width of the door is

[tex]120\times \frac{1}{50}=2.4 cm.[/tex]

Hence, on the drawing, the width of the kitchen door should be 2.4 cm.

The scale on the map is 1 centimeter is equal to 25 kilometers. On the map, the distance the towns along the highway is 4.5 centimeters. Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving. How many liters of gasoline to the nearest liter will Tori need to drive from one of these town to the other?

Answers

Answer: About 14 liters of gasoline is required.

Step-by-step explanation:

On the map,

1 centimeter= 25 kilometers.

Distance the towns along the highway is 4.5 centimeters.

Actual distance = 4.5 x 25 km

= 112.5 km

Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.

Total gasoline required = 0.123  x  112.5 km

= 13.8375 liters≈ 14 liters

hence, about 14 liters of gasoline is required.

0.5 1.5 2.5 3.5 4.5 5.5 6.5
Time (hours)

Answers

Answer:

t = 4.2 h

Step-by-step explanation:

We can calculate the time taken by the car to travel 400 miles, easily by taking a difference of time in graph between 0 miles and 400 miles value:

t₄₀₀ = 3.5 h - 0 h

t₄₀₀ = 3.5 h

Now, we calculate the constant speed of the car from the following formula:

s = vt

v = s/t

where,

v = velocity of the car = ?

s = distance covered by the car = 400 mi

t = time taken = 3.5 h

Therefore,

v = 400 mi/3.5 h

v = 114.28 mi/h

Now, for this uniform speed the time taken to cover the distance of 480 miles will be:

114.28 mi/h = 480 mi/t

t = (480 mi)/(114.28 mi/h)

t = 4.2 h

Mirna earned $120 baby-sitting during the spring break. She needs to save $90 for the German Club trip. She wants to spend the remainder of the money shopping. Use s for the amount of money Mirna can spend. Enter your inequality in the most simplified form.

Answers

Answer:

$30

Step-by-step explanation:

s + 90 = 120

s = 120 - 90

s = 30

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Where s is the amount to spend.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Mirna earned $120 babysitting during spring break.

She needs to save $90 for the German Club trip.

She wants to spend the remainder of the money shopping.

This means,

The remainder amount,

= 120 - 90

= $30

We can write an inequality as,

s ≤ 120 - 90

s ≤ 30

Where s is the amount of money to spend on shopping.

Thus,

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30
