You buy a pair of jeans for 25% markdown from $32.00. The sales tax is 6%. How much will you pay for the jeans?
Answer:
$25.44
Step-by-step explanation:
Although the starting price of the pair of jeans is $ 32, it is 25% off. Thus, 75% of its initial value (100-25) is being paid, with which the pre-tax price is determined as follows:
32 x 0.75 = X
24 = X
In turn, at that discounted price, 6% must be calculated as sales tax, with which the final price is determined through the following calculation:
24 x 1.06 = X
25.44 = X
Therefore, the price to pay for the pair of jeans is $ 25.44.
Answer:
$25.44
Step-by-step explanation:

Loren Weber wants to buy the sedan listed below. There is a 6% sales tax on the purchase price of the car. If Loren pays the full sticker price for the car? What is the total price?
Answer:$32,085
Step-by-step explanation:
$25,335+1,995+995+895+895+695+295+195+35+750= $32,085
Total price of the sedan that Loren Weber wants to buy = $34010.1
What Is a Sales Tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services. A conventional sales tax is levied at the point of sale, collected by the retailer, and passed on to the government.
Given,
CODE DESCRIPTION MSRP
SAL 4 4 Dr. Sedan AWD $25335
85N Navigation System $1995
66E Entertainment System $995
Chrome Wheel Covers $895
Interior Convenience Package $895
SS9 Safety & Security Package $695
RSS2 Reverse Sensing System $295
SR5 Satellite Radio $195
195 EBH9 Engine Block Heater $35
E43 Destination Charge $750
Full sticker Price = 25335+1995+995+895+895+695+295+195+35+750
Full sticker Price = $32085
6% sales tax = 0.06 × $32085 = $1925.1
Total price of the car = Full price + sales tax
Total price of the car = $32085 + $1925.1
Total price of the car = $34010.1
Hence, $34010.1 is the total price of the sedan that Loren Weber wants to buy.

Find the center and radius of the circle with the equation: (x-5)^2+(y+1)^2=4
Answer:
Centre (5,-1) radius =2
Step-by-step explanation:
(x-5)^2+(y+1)^2=4
The standard equation of the circle is
(X-a)^2+(y-b)^2=r^2
Where a,b is centre of the circle and r is the radius of the circle
Compare the equations
So we get a=5,b=-1 and r=2
Centre (5,-1) radius =2
Write an equation of the line with the given slope, m, and y-intercept (0,b)

Step-by-step explanation:
Given
[tex]m = 8[/tex]
[tex]b = 7[/tex]
[tex]y-intercept: (0,7)[/tex]
Required
Determine the equation
An equation has a general form as follows:
[tex]y = mx + b[/tex]
Next, we substitute values for m and b
Substitute 8 for m and 7 for b
[tex]y = 8x + 7[/tex]
Hence, the line equation is: [tex]y = 8x + 7[/tex]
x^2-8x-36
says “needs to be factored completely”
Step-by-step explanation:
x^2 - 8 - 36
x = (-(-8) ± √(-8)^2-4(1)(-36))/(2(1)) = (8 ± √64+144)/2 = 4 ± 0.5√208
x = (8+√208) or x = (8-√208)
therefore

If the square below has an area of 50, what is the value of x
Answer:
10
Step-by-step explanation:
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10

Which brand should the store eliminate?
O A. Brand B
O B. Brand D
O C. Brand C
O D. Brand A
Answer: They should eliminate Brand C
Step-by-step explanation:
You need to divide the total returns by the total sold to which Brand has the greatest percentage returned.
The brand that the store should eliminate out of the 4 given brands using the data in the table is; Brand C
How to Solve Percentage Problems?To find the brand that the store should eliminate we need to find the percentage of sold items that were returned and pick the highest percentage as the brand the store should eliminate.
Brand A percentage = [tex]\frac{33}{685}[/tex] × 100 = 4.81%
Brand B percentage = [tex]\frac{15}{492}[/tex] × 100= 3.04%
Brand C percentage = [tex]\frac{29}{361}[/tex] × 100 = 8.03 %
Brand D percentage = [tex]\frac{31}{766}[/tex] × 100 = 4.04%
Brand C has the highest percentage and as such it is the brand that should be eliminated.

When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. Find the probability that at least one plane has critical cracks.
Answer:
0.226
Step-by-step explanation:
Given that:
No wing crack (x) = 70%
Detectable wing crack (y) = 25%
Critical wing crack (z) = 5%
Number of samples (n) = 5
Probability that atleast a plane has critical crack:
1 - p(no critical crack)
Using the multinomial distribution calculator :
P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0)
From the calculator :
P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0) = 0.7741
1 - 0.7741 = 0.2259

x + y + z = 41.5
Step-by-step explanation:
(5x)° = 100°
x = 20
(4y + 10)° + 100° = 180° ⇒ y = [tex]\frac{35}{2}[/tex] = 17.5
(4z² + 16)° + 100° = 180° ⇒ z = 4
x + y + z = 20 + 17.5 + 4 = 41.5

Answer:
[tex]x + 15 = 60[/tex]
[tex]x = 60 - 15[/tex]
Step-by-step explanation:
Given
[tex]Additional = 15[/tex]
[tex]Total = 60[/tex]
Required
What equation can be used to select the initial number of stickers
Represent the initial number of stickers with x
The equation can then be written as:
[tex]x + Additional = Total[/tex]
This gives:
[tex]x + 15 = 60[/tex] ---- This is one equation
Make x the subject
[tex]x = 60 - 15[/tex] --- This is another equation
Solving further for x
[tex]x = 45[/tex]
This implies that she started with 45 stickers

b) Without graphing the function, determine the slope.
Answer:
15
Step-by-step explanation:
The function for the given situation is g(x)=7x+20.
Given that, Juan earns $7 per hour plus $20 per week making picture frames.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
a) Let the number of hours in a week be x.
So, function is g(x)=7x+20
y=7x+20
b) Compare y=7x+20 with y=mx+c, we get m=7
So, slope is 7
Therefore, the function for the given situation is g(x)=7x+20.

[tex]\frac{1}{3}[/tex]x-1
Step-by-step explanation:
([tex]\frac{5}{6}[/tex]x-7)-([tex]\frac{1}{2}[/tex]x-6) =
The - sign before 6 is turned into a + sign when the bracket is removed because the arithmetic operation before the bracket is - and two - makes the second - turn into a + (It's a rule I can't rlly explain it well but yea)
[tex]\frac{5}{6}[/tex]x-7-[tex]\frac{1}{2}[/tex]x+6 = [tex]\frac{5}{6}[/tex]x-1-[tex]\frac{1}{2}[/tex]x
-7+6 makes it a -1.
[tex]\frac{5}{6}[/tex]x-[tex]\frac{1}{2}[/tex]x-1 = [tex]\frac{5}{6}[/tex]x-[tex]\frac{3}{6}[/tex]x-1
To make the denominator of the two fractions the same, I multiplied the second fraction by 3 so that both denominators are 6.
[tex]\frac{5}{6}[/tex]x-[tex]\frac{3}{6}[/tex]x-1 = [tex]\frac{2}{6}[/tex]x-1
After making the denominator the same, I can directly do the equation for the numerators (5-3=2) and keep the denominator the same.
[tex]\frac{2}{6}[/tex]x-1 = [tex]\frac{1}{3}[/tex]x-1
Since 2/6 has a common factor which is 2, I can divide both the numerators and denominators so that the fraction can be simplified further into 1/3, its simplest form.

Step-by-step explanation:
The fifth power of (5+7) can be written as:
[tex]\left(5+7\right)^5[/tex]
Solving the expression to determine its equivalent
[tex]\left(5+7\right)^5[/tex]

Given the measures a = 10, b = 40, and A = 30°, how many triangles can possibly be formed?
Answer:
no triangle can be formed with the given values (i.e 0 triangle).
Step-by-step explanation:
Given;
length of side a, = 10
length of side b, = 40
angle A, = 30°
Apply sine rule to determine the angle of the second side (B);
[tex]\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2[/tex]
The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.
