The computer will cost $924.96 after 6% tax.
Total cost of laptopThe initial payment of the laptop made = $150.00
The remaining balance that would be made = 12 × 69.50
=$834
Therefore total cost of laptop before tax = 834 + 150
= $984
But tax is 6% of total cost =
[tex] \frac{6}{100} \times 984[/tex]
[tex] \frac{5904}{100} [/tex]
= $59.04
Therefore, total cost of laptop after tax = 984 - 59.04
= $924.96

Linda guessed her puppy's weight. Her percent error was 2.5%. Her puppy's actual weight is 8 pounds.
Linda overestimated the weight of her puppy.
What was Linda's estimate?
Answer:
8.2 pounds
Step-by-step explanation:
You multiply 8 by 2.5% so that would be 8×0.025=0.2
Then since she overestimated, add 0.2 to 8
8+0.2= 8.2 pounds
At an ocean depth of 20 meters, a buoy bobs up and then down 2 meters from the oceans depth. Four seconds pass from the time the buoy is at it's highest point to when it is at lowest point.Assume at x=0, buoy is at normal ocean depth
Use the sine tool to graph the function. The first pint must be in the midline and the second must be a maximum or minimum value on the graph closest to the first point
Answer:
We'll use a sin graph since at x=0 the buoy is at the y midline....
the period is 8 seconds (highest point to lowest point and back to highest point)
Frequency is 1/period 1/8
Starts at 20 (sine wave shifted up 20 m)

Find the values of p for which the quadratic equation 4x2 + px + 3 = 0 has equal roots.
Answer:
Step-by-step explanation:
You need to concern yourself with the +3. That will determine what the equal roots are.
(2x + √3)^2
Now expand this to see what p is. (Kind of a nasty question if you ask me).
4x^2 + 2x*√3 + (√3)^2
4x^2 + 2√3 x + 3 also possible is
4x^2 - 2√3 x + 3
So the answer is p = 2√3
The answer could also be p = -2√3
Answer:
p = ±4√3
Step-by-step explanation:
The discriminant of quadratic equation ax²+bx+c = 0 is ...
d = b² -4ac
In your quadratic, its value is ...
d = p² -4(4)(3) = p² -48
The discriminant will be zero when the quadratic has equal roots. In that case, the values of p are found by ...
d = 0
p² -48 = 0
p² = 48 . . . . . add 48
p = ±√48 . . . . take the square root
p = ±4√3 . . . . simplify
__
Another way to get there is by looking at the factoring of a quadratic with equal roots:
(ax +b)² = 0 = a²x² +2ab +b²
Comparing to the given quadratic, we find ...
a² = 4 ⇒ a = ±2 . . . . . . coefficient of x²
b² = 3 ⇒ b = ±√3 . . . . constant
p = 2ab = 2(±2)(±√3) . . . . coefficient of x
p = ±4√3

9. A 25 L sample of nitrogen is heated from 110 °C to 260 °C. What volume will the
sample occupy at the higher temperature?
Answer:
Using the Charles law equation
V1/T1=V2/T2
V1=25L
V2=?
T1=110°C
T1=110+273
T1=383K
T2=266°C
T2=266+273
T2=539K
25L/283K=T2/539K
T2=(25L×539K)/283K
T2=47.6L
Therefore at the temperature of 266°C, it will occupy 47.6L of volume.

Based on the system of equations, it is found that Ajay is 25 years old today.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
Based on the given information, we can say
Let Wale's age be x
Let Ajay's age be y
Ten years ago,
Wale = x - 10
Ajay = y - 10
If wale was twice as old as Ajay 10 years back, then;
x - 10 = 2(y - 10)
Since Wale will be 40 years old in 10 years, then;
x + 10 = 40
x = 40 - 10
x = 30
Recall that x - 10 = 2(y - 10)
30 - 10 = 2(y - 10)
20 = 2(y-10)
y = 20
Hence Ajay will be 20 years old today

Select the correct answer. Which equation matches the function shown in the graph?
Answer:
B) [tex]y=sin(x+\frac{\pi}{2})[/tex]
Step-by-step explanation:
Technically, since the function starts at its maximum, you could say the function is [tex]y=cos(x)[/tex], but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity [tex]cos(x)=sin(x+\frac{\pi}{2})[/tex] and we can see that the correct answer is B.
The equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.
What is sin function?It is defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.
It is given that:
A graph of a trigonometric function is given:
As we know,
y = sinx has a sinusoidal graph
Based on the graph we can apply a transformation to get the required function.
Applying transformation:
x → x + π/2
The sin function will shift left side by π/2 unit
The equation of the function becomes:
y = sin(x + π/2)
The equation of the function shown in the graph is y = sin(x + π/2)
Thus, the equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.

The actual distance between town A and twon b is 64 question # 10
Answer:
8 cm; from the table
Step-by-step explanation:
The equation gives the ground distance in terms of the map distance, so would have to be solved for x to be used to find map distance.
The graph is not shown.
The table appears correct, and includes the value 32 km for a map distance of 4 cm. The ground distance of interest is 64 km, which is twice that table value. That means the map distance will be twice the corresponding table value: 2×4 cm = 8 cm.

A total of 243 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two
times the number of adult tickets sold. How many adult tickets were sold?
Answer:
81 adult tickets
Step-by-step explanation:
Step 1:
Set up a system of equations
Since the adult tickets and student tickets add to 243, we can do
[tex]a+s=243[/tex]
and the student tickets sold were 2x the adult tickets, we can do
[tex]s=2a[/tex]
We can replace s in the first equation adding to 243 with 2a
[tex]a+s(2a)=243\\3a=243\\[/tex]
Step 2:
Solve for a. We can divide both sides by 3.
[tex]a=81[/tex]
Therefore, there were 81 adult tickets sold.
Step 3:
We can check our work! Since we learned earlier the student tickets are 2x adult tickets, we can multiply 81 by 2 and add that to 81 to see if it equals 243!
[tex]s=2a\\s=2(81)\\s=162[/tex]
And...
[tex]162+81=243[/tex]
So, 81 must be the answer!

So,
[tex]\sf{\angle{RSK = }}{\sf{\angle{RAK}}}[/tex]
[tex]\sf{\angle{ RSK = 32° }}[/tex]
By using Angle sum property
AngleRSA + AngleSAR + AngleARS = 180°
[tex]\sf{ 32° + 32° + }{\sf{\angle ARS = 180° }}[/tex]
[tex]\sf{\angle {ARS = 180° - 64° }}[/tex]
[tex]\sf{\angle{ARS = 116° }}[/tex]

If loga abc=x +1,
logb ab c=y+1, logc abc=z+1
then
x+
y+z
+2
Step-by-step explanation:
Given:
log_(a) abc = x+1,
log_(b) abc = y+1,
log_(c) abc =z+1
Asked: x + y + z + 2 = ?
Solution:
Let
log_(a) abc = x+1 ⇛log_(abc) a = {1/(x+1)} →→→Eqn(1)
log_(b) abc = y+1 ⇛log_(abc) b = {1/(y+1)} →→→Eqn(2)
log_(c) abc = z+1 ⇛log_(abc) c = {1/(z+1)} →→→Eqn(3)
On adding equation (1),(2) and (3) then
log_(abc) a + log_(abc) b + log_(abc) c = {1/(x+1) + {1/(y+1)} + {1/(z+1)}
⇛log_(abc) abc = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]
⇛1 = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]
⇛{(x+1)(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛{x(y+1)+1(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛{xy + x + 1 + y}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛{xy + x + y + 1}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛z(xy + x + y + 1) + 1(xy + x + y + 1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛xyz + xz + yz + z + xy + x + y + 1 = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)
⇛xyz + xz + yz + z + xy + x + y + 1 = y(z+1)+1(z+1) + z(x+1)+1(x+1) + x(y+1)+1(y+1)
⇛xyz + xz + yz + z + xy + x + y + 1 = yz + y + z + 1 + xz + z + x + 1 + xy + x + y + 1
⇛x+y+z = y + z + 1 + x + 1
⇛x+y+z = x + y + z + 2
Therefore, x + y + z + 2 = x + y + z
Answer: Hence, the value of x + y + z + 2 = x + y + z.
