Answer:
Step-by-step explanation:
Total weight of the barricade is 310 kg using 8 boxes of books
Each box of books weighs 30 kg
We need to determinethe weight of the table in order write the proper equation
Total wieght of the barricade = Table Weight + Book Weight
solving for Table Weight substract Book Weight from both sides
Total wieght of the barricade - Book Weight = Table Weight
310 - 8(30) = Table Weight
310 - 240 = Table Weight
70 = Table Weight
Total wieght of the barricade = Table Weight + Book Weight
W = 70 + 30x where x is the number of boxes

The equation g(t)=2+23.7t−4.9t2 models the height, in meters, of a pumpkin t seconds after it has been launched from a catapult. Is the pumpkin still in the air 8 seconds later? Explain or show how you know.
Answer:
The pumpkin is not in the air
Step-by-step explanation:
The equation is
[tex]g(t)=2+23.7t-4.9t^2[/tex]
Let us find when the pumpkin will reach the ground
[tex]0=2+23.7t-4.9t^2\\\Rightarrow -49t^2+237t+20=0\\\Rightarrow t=\frac{-237\pm \sqrt{237^2-4\left(-49\right)\times 20}}{2\left(-49\right)}\\\Rightarrow t=-0.08,4.91[/tex]
So, the pumpkin will reach the ground at 4.91 seconds. Hence, at 8 seconds the pumpkin will reach the ground.
ORAt [tex]t=8\ \text{s}[/tex]
[tex]g(8)=2+23.7\times 8-4.9\times 8^2\\\Rightarrow g(8)=-122\ \text{m}[/tex]
The height of the pumpkin is negative 122 m. This means it is lower than the ground. So, the pumpkin is not in the air 8 seconds later.

Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.
If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.
Answer: No he would have 8.5$
Step-by-step explanation:
15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short
If Eric buys the jumper, he will not have £10 left to give to his sister.
To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.
Initial amount Eric has = £15
Cost of the scarf = £8.50
Amount received from his nan = £20
Cost of the jumper = £18
Amount to give to his sister = £10
First, let's calculate Eric's remaining balance after buying the scarf:
Remaining balance = Initial amount - Cost of the scarf
Remaining balance = £15 - £8.50
Remaining balance = £6.50
Next, let's calculate Eric's balance after receiving money from his nan:
Total balance = Remaining balance + Amount received from nan
Total balance = £6.50 + £20
Total balance = £26.50
Now, let's check if Eric can still afford to buy the jumper:
If Eric buys the jumper:
New balance = Total balance - Cost of the jumper
New balance = £26.50 - £18
New balance = £8.50
The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.
Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.

A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5
Answer:
n^2 + 6n + 1
Step-by-step explanation:
Firstly, we have to evaluate AB
What we have to do is to multiply A and B
We have this as;
n(2n + 6) = 2n^2 + 6n
Now, we have to subtract the value of C from here and that is;
(2n^2 + 6n) - (n^2 - 1)
2n^2 + 6n - n^2 + 1
= 2n^2 -n^2 + 6n + 1
= n^2 + 6n + 1

Sara was thinking of a number. Sara adds 12, then divides by 7 to get an answer of 11. What was the original number?
Answer:
65
Step-by-step explanation:
Do the opposite of what the question gives you.
Sara has the number 11. She divided by 7, so you would multiply by 7:
11 x 7 = 77
Next, Sara added 12, so you will subtract by 12:
77 - 12 = 65
65 is the number Sara was thinking of.

Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

A has 2 it crosses the x axis 2x
B Has 1.
C has 2
D has none since it never touched the x axis
Option B is correct.
Quadratic function :If the graph of quadratic function crosses x - axis at two points then that function has two zeros.
If the graph of quadratic function crosses x - axis at only one point then that function has only one zero.If the graph of quadratic function do not crosses x - axis at any point then that function has no zeros.From given option, It is observed that option B graph crosses x- axis at only one point.Therefore, Option B graph represent a quadratic function that has only one zero.

Ashlee was born on 12/24/2002. How many eight-digit codes could she make using the digits in her birthday?
Answer:
840
Step-by-step explanation:
Given the date:
Birth date = 12/24/2002
Number of digits = 8 = 8! = (8*7*6*5*4*3*2*1) = 40320
Repeated digits :
digit 2 = 4 times = 4! = (4 * 3 *2 * 1) = 24
digit 0 = 2 times = 2! = 2*1 = 2
Therefore the number of 8 digit codes that can be formed is :
8! / (4! * 2!)
40320 / (24 * 2)
40320 / 48
= 840
Hence, 840 8 digit codes can be formed

which of the following is a difference of cubes?
a. 3x^9-64y^3
b. 15x^21-64y^3
c. 27x^15-9y^3
d. x^6+27y^9
Answer:
D: x^(6) + 27y^(9)
Step-by-step explanation:
A) 3x^(9) - 64y^(3)
The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.
B) 15x^(21) - 64y^(3)
Similar to the reason given in A above, the first term cannot be expressed as a cube.
C) 27x^(15) - 9y^(3)
In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.
D) x^(6) + 27y^(9)
This can be expressed as;
(x²)³ - (-3y³)³
This is therefore a difference of cubes
