i get a 25% discount (means decrease) at macys store. if i find a dress i like for $80, how much will i have to pay for it?
Answer:
you will pay $60
Step-by-step explanation:
25% (1/4) of 80 is 20
subtract 20 from the total (80)
80 - 20 = 60
$60
Answer:
60
Step-by-step explanation:
So if you get 25% off, you're basically paying 75%.
So first, convert the percentage to a decimal:
75% = 75/100 = 0.75
Now just multiply the decimal by the total cost:
80$ (0.75) = $60
If you can solve it please tell me (20 points)

A right rectangular container is 10 cm wide and 24 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 2.7 cm. Find the volume of the stone.
Answer:
648cm³
Step-by-step explanation:
The container is a cuboid thus:
volume of water is:
v=l×w×h
=10×24×7
=1680cm³
volume of water+stone=10×24×(7+2.7)
=10×24×9.7
=2328cm³
Thus volume of stone equals
2328-1680.
=648cm³

Answer:
b=-9
intersection point (3, -3)
Step-by-step explanation:
There are a couple of ways to do this. The method that does not involve calculus is to set the two equations equal and find 'b' such that there is exactly one solution.
x^2 -4x = y = 2x +b
In standard form, this is ...
x^2 -6x -b = 0 . . . . . . . we call this the "combined quadratic"
This will have one solution when the discriminant is zero. You may recall that the discriminant of quadratic ax^2 +bx +c is d = (b^2-4ac). We want ...
d = (-6)^2 -4(1)(-b) = 0
36 +4b = 0 . . . . . simplify
b = -36/4 = -9 . . . solve for b
Then the linear equation is ...
y = 2x -9
__
If the discriminant is zero, the solution to the "combined quadratic" is ...
x = -b/(2a) . . . . . . . . with a, b, c from the quadratic form (not y-intercept)
x = -(-6)/(2(1)) = 3
And the point of intersection of the line and the parabola is ...
y = 2(3) -9 = -3 ⇒ (x, y) = (3, -3)

Junior's brother is 1 1/2
meters tall. Junior is 1 1/5
of his brother's height.
How tall is Junior?
Answer:
Step-by-step explanation:
1 1/5 of 1 1/2 meters
= (1+1/5) x (1+1/2)
= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2
= 1 + 1/2 + 1/5 + 1/10
= 1 + (1x5+1x2+1)/10
= 1 8/10
= 1 4/5 meters
Answer:
1 4/5 meters
Step-by-step explanation:
1 1/5 of 1 1/2 meters
= (1+1/5) x (1+1/2)
= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2
= 1 + 1/2 + 1/5 + 1/10
= 1 + (1x5+1x2+1)/10
= 1 8/10
= 1 4/5 meters

What is the inverse relation of f(x)=1/5x−4/5?
y=1/5x−4
y=−1/5x+5/4
y=−5x−4
y=5x+4
Answer:
[tex]y' = 5x + 4[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]
Required
The inverse relation
[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]
Rewrite as:
[tex]y = \frac{1}{5}x - \frac{4}{5}[/tex]
Swap x and y
[tex]x = \frac{1}{5}y - \frac{4}{5}[/tex]
Multiply through by 5
[tex]5x = y - 4[/tex]
[tex]y = 5x +4[/tex]
Rewrite the new function as:
[tex]y' = 5x + 4[/tex]
In ADEF, f = 610 inches, e = 590 inches and ZE=70°. Find all possible values of ZF,
to the nearest degree.
Answer:
"76°" is the appropriate solution.
Step-by-step explanation:
Please find attachment of the diagram according to the given query.
The given values are:
In ΔDEF,
f = 610 inches
e = 590
∠E = 70°
∠F = ?
By using the law of sines, we get
⇒ [tex]\frac{Sin E}{e} =\frac{Sin F}{f}[/tex]
On substituting the values, we get
⇒ [tex]\frac{Sin70^{\circ}}{590} =\frac{SinF}{610}[/tex]
On applying cross multiplication, we get
⇒ [tex]SinF=\frac{610\times Sin 70^{\circ}}{590}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{61\times 0.95969262}{59}[/tex]
⇒ [tex]=\frac{57.3212499}{59}[/tex]
⇒ [tex]=0.971546608[/tex]
now,
⇒ [tex]F=Sin^{-1}(0.971546608)[/tex]
⇒ [tex]=76^{\circ}[/tex]
For which product or quotient is this expression the simplest form? (image attached)! please help :((
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)
(x-4)/2(x+4)

d.no solution
5. What is the value of z so that -9 and 9 are both solutions of x^2+z=103
Answer:
1. a2. b3. b4. b5. 22Explanation:
1.
n²-49=0
n=√49
n=7
2.
x²+64=0
x=√64
x=8
3.
if A=144x²
l = √A
l = √(144x²)
l = 12x
4.
b = (24×2)/3b
b = 48/3b
b = 16/b
b² = 16
b = √16
b = 4 in (-4 is correct in algebra but there's no negative lengths in geometric shapes)
5.
x²+z = 103
x² = 103-z
x = √(103-z)
for x = -9 and 9 (103-z) must equal 81
z = 103 - 81 = 22
x = √(103-22)
x = √81
x = -9 , 9

john takes a small business loan
for $18,000. the term for
repayment is 60 months and
the annual interest rate is 5.25%.
using the monthly payment
formula, what is the estimated
monthly payment?
9514 1404 393
Answer:
$341.75
Step-by-step explanation:
You have not provided the formula, so we'll use one we like:
A = P(r/12)/(1 -(1 +r/12)^(-n)) . . . . principal P, annual rate r, n months
A = $18,000(0.0525/12)/(1 -(1 +0.0525/12)^-60) ≈ $341.75
The monthly payment is about $341.75.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
64x = 8
Solve for x.
64x = 8
Divide both sides with 64.
x = 8/64
x = 1/8
Thus,
The value of x is 1/8.

Answer:
540
Step-by-step explanation:
If you do 15x12 which is the formula for area for a rectangle, you get 180. That's only the area of one rectangle but if you multiply it by 3 you get 540 for the areas added together.
Answer:
540 cm
