Brandi earned $140 from a summer job to buy new clothes for school. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found two pairs of shorts for $25 each and four shirts with an average cost of $19 per shirt. She will have to pay 7.5% sales tax.
Answer:
She will pay a tax of $9.45
Step-by-step explanation:
The question doesn't seem complete, but since we are given her tax rate, then they would surely ask for the amount of tax she paid. So let's work on this.
We are told that she bought two pairs of shorts and one short goes for $25 each, this implies that she will get the two for:
= $25 × 2
= $50
We are also told that she got four shirts that have an average cost of $19 per shirt. This implies that she will get the four shirt for:
= $19 × 4
= $76
Since she will have to pay a tax of 7.5%, then we will calculate it as:
= 7.5% × ($50 + $76)
= 0.075 × $126
= $9.45
Answer:
A. $9.45
B. Total cost = $135.45
Step-by-step explanation:
PART A: If she buys all of the items, how much sales tax will she have to pay?
The sales tax for Brandi's purchase will be $(insert answer here)
PART B: What is the total cost of her purchase including sales tax?
Brandi will spend $(insert answer here) on her purchases, including sales tax.
A.
Total amount earned = $140
Two pairs of shorts = $25 each
Total cost of 2 shorts = 2 shorts × $25 each
= $50
Four shirts = $19 each
Total cost of 4 shirts = 4 × $19
= $76
Amount of Sales tax = 7.5% of Total cost of 2 shorts + Total cost of 4 shirts
= 7.5% ($50 + $76)
= 0.075 × 126
= $9.45
Total cost = Total cost of 2 shorts + Total cost of 4 shirts + Amount of Sales tax
= $50 + $76 + $9.45
= $135.45
Therefore, she has enough money to buy all the items she likes

Sofia purchased a new car in 2007 for$34,000. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $16,200 in the year 2014, then what would be the predicted value of the car in the year 2021, to the nearest dollar?
Answer:
$7,718
Step-by-step explanation:
Given that :
Cost of car in 2007 = $34000
Cost of car in 2014 = $16200
Predicted value of car in 2021
Lets obtain the percentage Depreciation (d) :
Worth (A) of car in 2014 = $16200
Time (t) = 2014 - 2007 = 7 years
Initial cost (I) = price in 2007
A = I(1 - d/100)^7
16200 = 34000( 1 - d/100)^7
16200 = 34000(1 - 0.01d)^7
(16200/34000)^1/7= 1 - 0.01d
0.8995 = 1 - 0.01d
0.01d = 1 - 0.8995
d = 0.1005 /0.01
d = 10.05
Value of car in year 2021:
t = 2021 - 2007 = 14 years
A = I(1 - 10.05/100)^14
A = 34000(1 - 0.1005)^14
A = 34000(0.8995)^14
A = 34000 * 0.2269950
A =7717.83100
Approximate worth = $7718

Answer:
90 and 90
Step-by-step explanation:
If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90
Hope This Helps :)
The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.
What are perpendicular lines?In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Now it is given that,
Two distinct lines, L and M, are each perpendicular to the same line N.
Line L is perpendicular to line N.
Since angle between two perpendicular lines = 90°.
So, angle between line L and line N = 90°
Similarly, Line M is also perpendicular to line N.
Therefore, angle between line M and line N = 90°
Thus, The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.

If Y (-7,-4) and (5,2), find the slope of a line perpendicular to YZ. Please help if you can
Answer:
-2
Step-by-step explanation:
The slop of YZ is 1/2. The slope perpendicular would be opposite, making it -2.
Answer:
- 2
Step-by-step explanation:
Calculate the slope m of YZ using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = Y(- 7, - 4) and (x₂, y₂ ) = Z(5, 2)
m = [tex]\frac{2+4}{5+7}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2
A square and an equilateral triangle have the same perimeter. Each side of the triangle is 3 inches longer than each side of the square. Select the equation that will help you find the length of each side of the square.
Answer:
Step-by-step explanation:
Let the length of the side of the square be x
Perimeter of the square = 4x
Let the sides of the triangle be s1, s2 and s3
If each side of the triangle is 3 inches longer than each side of the square, then
s1 = x+3
s2 = x+3
s3 = x+ 3
Perimeter of the triangle P = s1+s2 + s3
If the square and thr triangle have the same perimeter then;
perimeter of square = perimeter of triangle
4x = s1+s2+s3
4x = x+3+ x+3+ x+3
4x = 3(x+3)
Hence the required equation is 4x = 3(x+3) where x is the side of the square.

Help me. Two numbers have a sum of 30. Half of their difference is 7. Find the numbers.
Answer:
the answer is x equals 22 and y equals 8
Step-by-step explanation:
first equation is x+y=30
Second equation is x-y/2=7 that simplify's to x-y=14
then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22
then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8
so the two numbers are 22 and 8
Hope this helps!!!!
The numbers satisfying the given conditions are 22 and 8.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
Two numbers have a sum of 30. Half of their difference is 7.
We can write the equations as -
x + y = 30
1/2(x - y) = 7
Rearranging, we get -
y = - x + 30
y = x - 14
Plot the graph, the point of intersection is the solution. The number will be 22 and 8.
Alternativelyy = - x + 30
y = x - 14
Equating both, we get -
- x + 30 = x - 14
30 + 14 = 2x
2x = 44
x = 22
and
y = 22 - 14
y = 8
Therefore, the numbers satisfying the given conditions are 22 and 8.

[tex] {x}^{4} - 6 {x}^{3} + 22 {x}^{2} - 48x + 40[/tex]
find the zeros
Answer:
x = 2, 1 + 3i, 1 − 3i
Step-by-step explanation:
Find the Roots (Zeros)
x^4 − 6x^3 + 22x^2 − 48x + 40
Set x^4 − 6x^3 + 22x^2 − 48x + 40 equal to 0. x^4 − 6x^3 + 22x^2 − 48x + 40 = 0
Solve for x.
Factor the left side of the equation.
Factor x^4 − 6x^3 + 22x^2 − 48x + 40 using the rational roots test.
(x − 2) (x^3 − 4x^2 + 14x − 20) = 0
Factor x^3 − 4x^2 + 14x − 20 using the rational roots test.
(x − 2) (x − 2) (x2 − 2x + 10) = 0
Combine like factors.
(x − 2)2 (x^2 − 2x + 10) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
(x − 2)^2 = 0
x^2 − 2x + 10 = 0
Set (x − 2)^2 equal to 0 and solve for x.
Set (x − 2)^2 equal to 0.
(x − 2)^2 = 0
Solve (x − 2)^2 = 0 for x.
x = 2
Set x^2 − 2x + 10 equal to 0 and solve for x.
Set x^2 − 2x + 10 equal to 0. x^2 − 2x + 10 = 0
Solve x^2 − 2x + 10 = 0 for x.
Use the quadratic formula to find the solutions.

Simplify.
Simplify the numerator.
x = 2 ± 6i/ 2.1
Multiply 2 by 1
x = 2 ± 6i/2⋅1
Simplify
2 ± 6i/2
x = 1 ± 3i
The final answer is the combination of both solutions.
x = 1 + 3i, 1 − 3i
The final solution is all the values that make (x − 2)2 (x2 − 2x + 10) = 0 true.
x = 2, 1 + 3i, 1 − 3i
