The Martin’s want to buy a new computer. The regular price is $849. The store is offering a 20% discount and a sales tax of 6% is added after the discount. What is the total cost of the computer?
Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:

Number 1: t=8m
Number 2: 2.50d=x
How do I find out the exact solutions and approximate solutions?
Answer: Exact solutions are x = 2√2 and x = -2√2
Approximate solutions are x = 2.828 and x = - 2.828
The attachment shows a portion of the graph with this equation. The "zeros" are the solutions.
Step-by-step explanation: To get values for x, we need to isolate x
2x² -6 = 10 Add 6 to both sides and rewrite the equation as
2x² = 16 divide both sides by 2
x² = 8 Factor 8 as 4(2) so you can "pull out" a square.
To solve for x, take the square roots of both sides.
Remember that square roots are positive and negative values.
[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{4(2)}[/tex]
x = ± 2√2
x = 2√2 and x = -2√2
We can use a calculator to get approximate values of x.
[tex]2\sqrt{2}[/tex] = ±2.828427125
Round that to x = 2.828 or 2.83 AND x = - 2.828 for approximate values.
What is the circumference of this circle?
Answer:
12.56
Step-by-step explanation:
its really 12.57 but yeah
Step-by-step explanation: To find the circumference of
the circle shown here, start with the formula c = 2πr.
Since the radius is 2 km, we can plug is 2 km for r in the formula.
So we have (2)(π)(2 km) which is equal to 4π km.
Now, remember that π is approximately equal to 22/7 or 3/14.
So we can estimate the value of the
circumference by plugging in 2.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference is approximately equal to 12.56km.

The area of a trapezium is 550 cm2 and the length of the parallel sides is 23cm and 27cm, find the distance between them.
Answer: 22 cm.
Step-by-step explanation:
Formula for area of trapezium: [tex]Area = \dfrac12 (\text{Sum of parallel sides})\times \text{(Distance between them)}[/tex]
Given: Area = [tex]550\ cm^2[/tex]
Length of parallel sides : 23 cm and 27 cm
Let h=distance beteen them.
then
[tex]550=\dfrac12 (23+27)(h)\\\\\Rightarrow\ 550=\dfrac12(50)h\\\\\Rightarrow\ 550=25h\\\\\Rightarrow\ h=\dfrac{550}{25}\\\\\Rightarrow\ h= 22[/tex]
Hence, the distance between them = 22 cm.

For the linear equation, find the product of 5 and the linear equation, and solve both equations for y. 2x + 7y = 11
Answer:
(a) [tex]10x + 35y = 55[/tex]
(b) [tex]y = \frac{11 - 2x}{7}[/tex]
Step-by-step explanation:
Given
[tex]2x + 7y = 11[/tex]
Solving (a): Multiply equation by 5.
Multiply both sides by 5
[tex]5 * (2x + 7y) = 11*5[/tex]
Open bracket
[tex]5 * 2x + 5 * 7y = 11*5[/tex]
[tex]10x + 35y = 55[/tex]
(b) Solve for y in [tex]10x + 35y = 55[/tex] and [tex]2x + 7y = 11[/tex]
[tex]10x + 35y = 55[/tex]
Subtract 10x from both sides
[tex]35y = 55 - 10x[/tex]
Divide both sides by 35
[tex]\frac{35y}{35} = \frac{55 - 10x}{35}[/tex]
[tex]y = \frac{55 - 10x}{35}[/tex]
Factorize the numerator:
[tex]y = \frac{5(11 - 2x)}{35}[/tex]
Express 35 as 7 * 5
[tex]y = \frac{5(11 - 2x)}{7 * 5}[/tex]
[tex]y = \frac{(11 - 2x)}{7}[/tex]
[tex]y = \frac{11 - 2x}{7}[/tex]
When [tex]2x + 7y = 11[/tex] is solved, the solution will be: [tex]y = \frac{11 - 2x}{7}[/tex]

One evening, a restaurant served a total of 5/6 of a loaf of wheat bread and 3/10 of a loaf of white bread. How many loaves were served in all?
Answer:
1 2/15 loaves
Step-by-step explanation:
In a restaurant:
Total Loaf of wheat bread = 5/6
Total Loaf is white bread = 3/10
The total number of loaves that were served in all =
Loaf of wheat bread + Loaf of white bread
= 5/6 + 3/10
Lowest Common Denominator = 30.
Hence:
= 25 + 9/30
= 34/30
= 1 4/30
= 1 2/15 loaves
The total number of loaves served in all = 1 2/15 loaves

A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and yellow paint are needed to make 21 pints of the green paint? A. 12 pints of blue paint and 3 pints of yellow paint B. 9 pints of blue paint and 12 pints of yellow paint C. 16 pints of blue paint and 9 pints of yellow paint D. 12 pints of blue paint and 9 pints of yellow paint
Answer:
D
Step-by-step explanation:
The sum of the ratios = 4 + 3 = 7
The ratio of blue paint to the total paint = 4/7
The ratio of yellow paint to the total paint = 3/7
Pints of blue paint needed to make 21 pints of the green paint = 4/7 x 21 = 12 pints
Pints of yellow paint needed to make 21 pints of the green paint = 3/7 x 21 = 9 pints

What equation in slope-intercept form represents the line that passes
through the points (3,-2) and (1, -3)?
Answer:
2y = x - 7
Step-by-step explanation:
The general equation of the line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1, y1) = (3,-2)
(x2,y2) = (1,-3)
m = (-3+2)/(1-3) = -1/-2 = 1/2
So we have the equation as;
y = x/2 + b
Multiply through by 2
2y = x + 2b
To get the y-intercept value, we substitute any of the points
Let us use the first point
While 3 will go for x , -2 will go for y; thus we have;
2(-2) = 3 + 2b
-4 = 3 + 2b
2b = -4-3
2b = -7
b = -7/2
So the equation is;
2y = x -7
