Jennifer wrote the expression: (2x3 + 3x2 + 2x – 4) – (x3 – 2x2 – x – 1). What is the simplified form of this expression?

Answers

Answer 1
We have

2x³+3x²+2x-4-(x³-2x²-x-1). Using the distributive property, we get 
2x³+3x²+2x-4-x³+2x²+x+1
Adding and subtracting like terms (e.g. x³+3x³=4x³), we get 
x³+5x²+3x+3

The shelf is made of 3 pieces of wood, each 0.3 meter wide. There is also 0.05 meter of space between the shelf and the wall on each side. What is the width, in meters, of the closet?

A. 0.4
B. 0.8
C. 1
D. 1.9

Answers

The correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.

To determine the width of the closet, we need to add up the widths of the three pieces of wood and the spaces on each side.

Given:

- Width of each piece of wood: 0.3 meters

- Number of pieces of wood: 3

- Space on each side between the shelf and the wall: 0.05 meters

Now, calculate the total width:

[tex]\[ \text{Total Width} = (\text{Width of one piece of wood} \times \text{Number of pieces of wood}) + (\text{Space on one side} \times 2) \][/tex]

[tex]\[ \text{Total Width} = (0.3 \times 3) + (0.05 \times 2) \][/tex]

[tex]\[ \text{Total Width} = 0.9 + 0.1 \][/tex]

[tex]\[ \text{Total Width} = 1 \, \text{meter} \][/tex]

The width of the closet is 1 meter, considering the combined width of the three pieces of wood and the spaces on each side.

Therefore, the correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.

list the independent and dependent variables for each situation:
(a) my height depends on my age.
(b) the amount of sleep I get determines what mood I am in.
(c) the amount of water in a bathtub is a function of the amount of time the water has been running.
(d) my distance from home varies with my speed.
(e) the amount of homework I do affects my average speed.
(f) the amount of homework I do depends on how much is assigned.

Answers

Part (a)

Independent variable = age
Dependent variable = height

"depends on age" indicates that age is independent. 

-----------------------------------
Part (b)

Independent variable = amount of sleep
Dependent variable = mood

The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)

Independent variable = time water has been running
dependent variable = amount of water in the tub

Time is usually the independent variable
-----------------------------------
Part (d)

Independent variable = speed
dependent variable = distance from home

-----------------------------------
Part (e)

Independent variable = amount of homework done
dependent variable = speed

This seems like an odd pairing of homework and speed. Could there be a typo? I noticed that part (f) is very similar

-----------------------------------
Part (f)

Independent variable = amount of hw that is assigned
dependent variable = amount of homework done

Like with part (a), the stuff before "depends" is the dependent variable

-3(y-5)=24 What is y ?

Answers

Distribute into the parenthesis and you get: -3y+15=24. Now, subtract 15 on both sides and you will get: -3y = 9. Finally, divide -3 on both sides and you will get the final answer: y = -3. You can check your answer by substituting -3 into the original equation: -3(-3-5) = 24. 9 + 15 = 24. 24 = 24
 -3(y - 5) = 24             Use the Distributive Property.
 -3y + 15 = 24            Subtract 15 from both sides of equation.
 -3y = 9                       Divide -3 from both sides of the equation.
 y = -3                         This is your final answer.

Marcus sorts his 85 baseballs cards into stacks of 9 cards each. How many stacks of 9 cards Marcus make

Answers

Hello!

To get your answer, you must divide:

85/9 = 9.4

So, Marcus made 9.4 stacks of cards.

I really hope you found this helpful! :)

Marcus can make 9 full stacks.

To determine how many stacks Marcus can make, we need to perform a division of the total number of baseball cards by the number of cards per stack.

Total number of baseball cards: 85.

85 ÷ 9.

= 9 (with a remainder of 4.)

This means Marcus can make 9 full stacks of 9 cards each with 4 cards left over.

Answers

To find the better buy we have to find the cost per pen for each.

1. 20 pens for $1.60 -> 1.60/20 = .08 cents per pen.
25 pens for $2.25 -> 2.25/25 = .09 cents per pen.

The best buy is 20 pens for $1.60 because it's cheaper per pen. 

2. 13 berries for $2.60 -> 2.60/13 = .20 cents per berry
17 berries for $3.06 -> 3.06/17 = .18 cents per berry

The best buy is 17 berries for $3.06 because it's cheaper per berry.

The histogram shows the scores of students on their most recent history test. How many students scored 80% or better on the test?

Answers

Final answer:

The number of students who scored 80% or better can be partially determined from the histogram data, with five students explicitly scored between 90 and 99%. The exact number scoring between 80 and 89% isn't provided, but those students would also be included in the count.

Explanation:

To determine how many students scored 80% or better on their most recent history test, we need to focus on the histogram's data for the ranges of 80 to less than 90 and 90 to less than 100. According to the information provided, five students scored between 90 and 99% (A range). However, the exact number of students who scored between 80 and 89% is not directly stated. Nevertheless, the data suggest that most students scored within the 70-89% range, with some scoring in the 60-69% range and a few in the 90-100% range.

Given that five students received an A (90-99%), and assuming the distribution includes students scoring between 80-89%, we would also count those students. Without the specific number for the 80-89% range, it's crucial to analyze the provided data to estimate or directly state numbers within this context. Thus, our primary focus for students who scored 80% or better combines those explicitly mentioned five students with an undefined number scoring within the 80-89% range.

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.

Answers


It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.

Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.

y+30=3y-50
-2y+30=-50
-2y=-80
y = 40

C)40.
Final answer:

Setting the given equations equal to each other, we can solve for y and determine that y equals 40.

Explanation:

The question states that OF bisects EOF, which means that EOF and FOG are equal. Hence, you can set the two equations equal to each other to solve for y.

EOF = y + 30FOG = 3y - 50

Set EOF equal to FOG:

y + 30 = 3y - 50

To solve for y, first simplify the equation by subtracting y from both sides:

30 = 2y - 50

Then add 50 to both sides to isolate the y variable on one side:

80 = 2y

Finally, divide both sides by 2 to solve for y:

y = 40
