Answer:
Option C.
Step-by-step explanation:
Kay has the number 9.653
We want to find a number such that if we multiply this one by that number, the product will be larger than 9.6537
First, you need to notice that 9.6537 > 9.653
Now you need to remember that if we have a number A and a number B.
A*B > A if B > 1
A*B = A if B = 1
A*B < A if 0 < B < 1
Then we need to find an option with a number larger than 1.
Also, a rational number a/b is larger than 1 only if a > b
The only option which has an option larger than 1 is C.
C: 9/4 = 8/4 + 1/4 = 2 + 1/4

Step-by-step explanation:
It would be the middle of the 6 and 5 because you go -4 plus to to the left and in half would be in the middle of that.
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

Ann buys a dress in a sale. The normal price of the dress is £36 and it is reduced by 20%. Work out the sale price of the dress.
Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
36 x 0.8 = 28.80
The sale price is £28.80

Suppose on April 1, a gag store sold a total of 27 widgets and wombats combined. If widgets cost
$0.75, wombats cost $1.25, and the store received a total of $27.75 for these two items, how
many of each item did the store sell?
Answer:
Widgets: 12
Wombats: 15
Step-by-step explanation:
Let x represent widgets
y represent wombats
Set up the equations
(1) x + y = 27
(2) 0.75x + 1.25y = 27.75
Solve equation (1), x + y = 27 for x
x = 27 - y
Substitute 27- y for x into equation (2)
0.75(27 - y) + 1.25y = 27.75
0.5y + 20.25 = 27.75
0.5y = 7.5
y = 15
Substitute 15 for y into equation (2)
x = 27 - 15
= 12
Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where x is the number of years since he bought his truck.
In how many years will his truck be worth $4,800?
Answer:
28 years
Step-by-step explanation:
The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

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

Sea x número de casos Infectados en Santiago
Sea 2x + 5,088 números de casos Infectados en Sto. Dgo.
Entonces x + 2x + 5,088 = 43,956
x + 2x = 43,956 - 5,088
3x = 38,868
x = 38,868

x = 12,912

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

Answer:
1442.9 = 1.4429 x 10 ^1000
Step-by-step explanation:
PEMDAS
4.3 × 107 + 9.1 × 108 = _____ x 10 ^----
(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---
460.1 + 982.8 = _____ x 10 ^----
1442.9 = 1.4429 x 10 ^1000
This is the right answer, I think you may have forgotten to put the ^.
Answer:
9.53 × 108
Step-by-step explanation:
Make sure both numbers have the same exponent
4.3 × 107 = 0.43 × 108
Then add the coefficients
0.43 × 108 + 9.1 × 108 = 9.53 × 108

Answer:
x = 4
Step-by-step explanation:
Given
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]
Multiply through by (x + 3)(x + 4) to clear the fractions
3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side
3x + 9 - x - 4 = x + 9
2x + 5 = x + 9 ( subtract x from both sides )
x + 5 = 9 ( subtract 5 from both sides )
x = 4

Which graph best represents a quadratic function that has only one zero?
Answer:
B
Step-by-step explanation:
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.
