Answer: [tex]\$1139[/tex]
Step-by-step explanation:
Given
The original cost of the laptop is [tex]\$1340[/tex]
A sale of 15% is applicable on it
The buyer has to pay 15% less
So, the effective price of the laptop is
[tex]\Rightarrow 1340-15\%\times 1340\\\Rightarrow 1340(1-0.15)\\\Rightarrow 1340\times 0.85\\\Rightarrow \$1139[/tex]
So, the final price of the laptop is [tex]\$1139[/tex].

Which number is the numerator in the fraction 1/2
Answer:
1
Step-by-step explanation:
The denominator is the bottom number, and represents how many parts are possible—in other words, how many parts go into a whole. The numerator is the top number, and represents how many parts you have.
[tex]\frac{Numerator}{Denominator}[/tex]
Answer:
The numerator is 1.
Step-by-step explanation:
The numerator is the number above the fraction bar; the denominator is below.
[tex]\frac{denominator}{numerator} -\frac{1}{2}[/tex]
) () = 2 − 6 + 13 Translate f(x) 7 units to the left and down 5 units. Write your new function in vertex form
Answer:
[tex]y= (x -4)^2 - 1[/tex]
[tex]Vertex = (4,-1)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2 + 6x+13[/tex]
Required
7 units left and 5 units down
First, we have: [7 units left]
The rule is:
[tex](x,y) \to (x-7,y)[/tex]
So, we have:
[tex]f(x) = (x - 7)^2 + 6(x -7)+13[/tex]
Next, we have: [5 units down]
The rule is:
[tex](x,y) \to (x,y-5)[/tex]
So, we have:
[tex]f'(x) = (x - 7)^2 + 6(x -7)+13 - 5[/tex]
[tex]f'(x) = (x - 7)^2 + 6(x -7)+8[/tex]
Rewrite as:
[tex]y = (x - 7)^2 + 6(x -7)+8[/tex]
Expand
[tex]y = x^2 - 14x + 49 + 6x -42+8[/tex]
Collect like terms
[tex]y = x^2 - 14x + 6x -42+8+ 49[/tex]
[tex]y = x^2 -8x +15[/tex]
To write in vertex form, we have
Subtract 15 from both sides
[tex]y -15= x^2 -8x[/tex]
Divide (-8) by 2; Add the square to both sides
[tex]y -15+ (-8/2)^2= x^2 -8x + (-8/2)^2[/tex]
[tex]y -15+ 16= x^2 -8x + 16[/tex]
[tex]y +1= x^2 -8x + 16[/tex]
Expand
[tex]y +1= x^2 -4x - 4x + 16[/tex]
Factorize
[tex]y +1= x(x -4) -4(x - 4)[/tex]
Factor out x - 4
[tex]y +1= (x -4)(x - 4)[/tex]
Rewrite as:
[tex]y +1= (x -4)^2[/tex]
Make y the subject
[tex]y= (x -4)^2 - 1[/tex]
The vertex is:
[tex]Vertex = (4,-1)[/tex]

Step-by-step explanation:
a.) because the sides are the same their angles must be too
let x be the angle
100+x+x=180
x=40
b.) because the angles are all the same their sides must be too

In triangle DEF, find the missing side as an exact value:
Answer:
8.60
Step-by-step explanation:
the diagram is optically misleading.
how can the 5 side be longer than the 7 side ?
but ignore that.
the important thing is that this is a triangle with a 90 degree angle.
so, we use Pythagoras' formula : a^2 + b^2 = c^2
we know a and b as 7 and 5.
so, the equation is 7^2 + 5^2 = c^2
=> 49 + 25 = c^2
=> 74 = c^2
=> the missing side length c is
[tex] \sqrt{74} = 8.60[/tex]

y=-3x
hope that answers your question
Step-by-step explanation:
Answer: C. y = -3x
Step-by-step explanation:
Since the line runs through the origin (0, 0), we don't have to write a y-intercept. To calculate the slope, we determine the change in y value over the change in x value.
Looking at the graph, we see that for every +1 x, we have -3 y, so the slope is -3, which we multiply by x in the equation.
Given the equation: y = 3 (2x - 1) Complete the table of values. y - 1 0 9
Answer:
Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

At birth, the rhino weighed 85 pounds. The rhino gained the same amount of pounds each month for 6 months. After 6 months, the rhino weighed 493 pounds. How much weight did it gain each month?
Answer:
68 pounds a month
Step-by-step explanation:
so what i did is subtract 85 because that was the starting weight, now we have 408 I divided 6 (how many months) and got 68.

Answer:
26
Step-by-step explanation:
[tex] In\: \odot Y, [/tex] WZ is tangent to the circle at point Z and YZ is radius.
[tex] \therefore YZ \perp WZ[/tex]
(tangent radius theorem)
[tex] \therefore m\angle WZY = 90\degree [/tex]
Since, side opposite to 90° angle is called hypotenuse.
So, x represents the length of hypotenuse of [tex] \triangle WYZ[/tex]
Thus, by Pythagoras Theorem
[tex]x = \sqrt{ {24}^{2} + {10}^{2} } \\ \\ = \sqrt{576 + 100} \\ \\ = \sqrt{676} \\ \\ = 26[/tex]
Answer:
this answer is not right because the Y is not 90 degrees the Z angle is 90 degrees so the answer should be 26
if the trangle is right trangle use Phythagoras
576-100=476=x²
x²=476

Write the equation of the line with slope -7/8 and y-intercept of -4/5
Answer:
y= -7/8 - 4/5
Step-by-step explanation:
y=mx+b
y= -7/8 + y intercept (b)
so y= -7/8 - 4/5

Planet x is 23 of a light-year away from Earth. Planet Y is 13 of a light-year away from Earth. How much farther away is Planet X?
Answer:
Planet X is 1.77 times further from Earth than Planet Y.
Step-by-step explanation:
Given that Planet X is 23 of a light-year away from Earth, while Planet Y is 13 of a light-year away from Earth, to determine how much farther away is Planet X the following calculation must be performed:
13 = 1
23 = X
23/13 = X
1.769 = X
Therefore, Planet X is 1.77 times further from Earth than Planet Y.

Calculate the sphere volume vv
Answer:
The volume of the sphere equals 2,393.9 [tex]cm^{3}[/tex] if we were to round to the nearest tenth.
Step-by-step explanation:
The volume of the sphere can be found by using the following formula...
(In the following formula "r" is the radius)
Volume = (4π[tex]r^{3}[/tex]) / 3 = [tex](4)(3.14)(8.3)^{3} / 3[/tex] ≅ 2,393.9 [tex]cm^{3}[/tex]
Answer:
2393.9
Step-by-step explanation:
4πr³/3=4π(8.3)³/3=4π*571.787/3=4*3.14*571.787/3≈2393.9
