A x^2-1
B x^2-12
C 2x-1
D x^2-1/2x-12
Answer:
B
Step-by-step explanation:
(2x^3 - x^2 - 24x + 12) / (2x - 1) = x^2-12
(use long polynomial division)
Answer:
[tex]\boxed {\sf B.\:x^2-12}[/tex]
Step-by-step explanation:
[tex]\sf \cfrac{2x^3-x^2-24x+12}{2x-1}[/tex]
Factor the expressions that aren't already factored:
[tex]\sf \cfrac{(2x-1)(x^2-12)}{2x-1}[/tex]
Cancel out 2x-1 in both sides numerator and denominator:
[tex]\sf x^2-12[/tex]

What is the surface area of this triangular pyramid?
Answer:
48.25
Step-by-step explanation:
This is because when finding the area of a triangle it is known as base times height then divide by 2 and since the base is a triangle, multiply 4.3 times 5 which is 21.5 and divide by 2 which is 10.75 and for the top since its also a triangle multply 5x5 which is 25 divide by 2 whicih is 12.5, but there is 3 of them so multiply by 3 and you get 37.5, then add 37.5+10.75 to get 48.25 cm^2
Sally flipped a penny 25 times and landed on heads 16 out of the 25 times. If she plans to flip the coin 100 times,
how many times can she expect to land on heads?
Answer:
50 times
Step-by-step explanation:
Since the odds of her getting a heads is 50% (1/2) every time she flips the coin. So she should expect to get 50 heads. However this number varies practically because in every single flip there is a 50-50 chance. If she had flipped it infinitely many times then it would be exactly 50%

What is square root and cube root of a number?
Square root of a number results a number that when square, gives us the previous number.
Similarly, cube root of a number results a number that when cubed, gives us the previous number.
Here, [tex]\sqrt[3]{64}[/tex]² = ∛(64 × 64) = ∛(8 × 8 × 8 × 8 × 8 × 8) = 8 × 8 = 64
[tex]16^{3/2}[/tex] = 4³ = 64
[tex]\sqrt[3]{8^{4} }[/tex] = ∛(8 × 8 × 8 × 8) = ∛(64 × 64) = ∛(4 × 4 × 4 × 4 × 4 × 4) = 4 × 4 = 16
√(16²) = √(16 × 16) = 16
Therefore, [tex]\sqrt[3]{64}[/tex]² and [tex]16^{3/2}[/tex] have the greatest value.

A rectangular painting has an area of 420 square inches. If the length is (2x + 5) inches and the width is (x) inches, then what is the value of x? Use completing-the-square and round the value of x to the nearest tenth. (Hint: You may find 2 solutions, but you only need the positive solution because the length and width must be positive values)
Answer:
12.1 inches
Step-by-step explanation:
Since the length of the rectangular painting is (2x + 5) inches and its width is x inches, it area A = (2x + 5)x square inches = 2x² + 5x.
Also, A = 420 square inches. So,
2x² + 5x = 420
2x² + 5x - 420 = 0
diving through by 2, we have
2x²/2 + 5x/2 - 420/2 = 0/2
x² + 5x/2 - 210 = 0
adding halt the coefficient of x squared to both sides, that is (5/2 ÷ 2)² = (5/4)² to both sides, we have
x² + 5x/2 + (5/4)² - 210 = 0 + (5/4)²
Simplifying, we have
(x + 5/2)² - 210 = 25/16
adding 210 to both sides, we have
(x + 5/2)² - 210 + 210 = 25/16 + 210
(x + 5/2)² = 25/16 + 210
(x + 5/2)² = (25 + 3360)/16
(x + 5/2)² = 3385/16
taking square root of both sides, we have
√(x + 5/2)² = ±√(3385/16)
(x + 5/2) = ±√3385/4
(x + 5/2) = ±58.18075/4
(x + 5/2) = ±14.55
x = -5/2 ±14.55
x = -2.5 ±14.55
x = -2.5 - 14.55 or -2.5 + 14.55
x = - 17.05 or 12.05
Since x = width and it cannot be negative, we choose the positive answer. So, x = 12.05 inches ≅ 12.1 inches (to the nearest tenth)

One pound of pasta noodles can be made using the ingredients shown in the recipe below. A chef uses 166 1/4 cups of flour each week to make noodles. How many pounds of noodles does the chef make each week?
Answer:
Pounds of noodles made per week = 47 1/2 pounds
Step-by-step explanation:
One pound of pasta noodles can be made using the ingredients shown in the recipe below.
Recipe for Pasta Noodles
Ingredients
3 1/2 cups of flour
4 large eggs
2 teaspoons of olive oil
A chef uses 166 1/4 cups of flour each week to make noodles. How many pounds of noodles does the chef make each week?
28 1/2
47 1/2
53 1/4
55 1/2
Pounds of noodles made per week = Total cups of flour used each week / flour used per pound
= 166 1/4 ÷ 3 1/2
= 665/4 ÷ 7/2
= 665/4 ÷ 2/7
= (665*2)/(4*7)
= 1330/28
= 47.5 pounds
Pounds of noodles made per week = 47 1/2 pounds

If an object is moving at 8m/s and slows down to a stop in 2 seconds. What is the objects acceleration
Answer:
-4m/s
Step-by-step explanation:
substitution 2x - 3y + = -45, x + 6y = 45
Answer:
y = 9
x = -9
Step-by-step explanation:
2x - 3y + = -45
x + 6y = 45, x = 45 - 6y
substitute for x:
2(45 - 6y) - 3y = -45
90 - 12y - 3y = -45
combine like terms:
90 - 15y = -45
15y = 135
divide both sides of the equation by 15:
y = 9
x = 45 - 6(9) = -9
Camille buys a cake for $24.99 . She also buys 12 brownies. Each brownie costs the same amount. She spends $39.99 on the cake and the brownies. Camille finds the cost of each brownie by calculating (39.99 - 24.99) *12 . Tanya finds the cost of each brownie by solving the equation $39.99 + 12b = 24.99 , where b is the cost of each brownie. Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither?

Jim borrows $210 from his sister at an 8% interest for seven years. How much interest does Jim have to pay?
Answer:
$117.6
Step-by-step explanation:
Formula:
I = Prt
Given:
P = 210
r = 8% = 0.08
t = 7
Work:
I = Prt
I = (210)(0.08)(7)
I = 117.6
Answer:
Step-by-step explanation:
So with 8% interest, Jim will have to pay 8% more each year. For the first year we need to multiply 210 with 1.08 to find the amount that Jim would have had to pay to his sister if he had gotten an 8% interest for 1 year. Every time the year increases we need to multiply the previous number with 1.08 because we are looking for the 8% increased value of the previous one, therefore our equation is:
P(t) = 210*(1.08)^t --> (t=time in years, P(t)=amount of money Jim need to pay back with respect to time)
Since Jim gets an 8% interest for 7 years we have to put in 7 for t.
P(7)=210*(1.08)^7
which is approximately $359.903

Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?
Answer:
27 years approx
Step-by-step explanation:
Given data
Principal P= $ 3,000
Final amount A= $ 7000
Rate r= 5%
The simple interest expression is
A=P(1+rt)
substitute and solve for t
7000=3000(1+0.05t)
7000=3000+150r
7000-3000=150r
4000=150t
t= 4000/150
t= 26.66
Hence, the time is 27 years approx
