A store is having a 25% off sale on all shirts. Select all of the possible ways to calculate the sale price for a shirt that normally costs $24.
A. 24 - (0.25 x 24)
B. (0.75) x 24
C. (0.25 x 24) x 3
D. (0.25 x 24)
E. (24 + 0.25)
Answer:
A,B, and C
Step-by-step explanation:
25%of 24 is 6, 24-6=18(new price)
A.24-(0.25×24)=24-6=18
B.(0.75)×24=18
C.(0.25×24)×3= 6×3=18
At what rate did you invest your $1000, if it made you $120 in interest over the course of 3 years? (Write your answer as a percent without the percent sign)
Answer:
The rate at which the $1000 is invested is 4%.
Since the answer is required to be written without the percent sign, it therefore implies that he rate at which the $1000 is invested is 4.
Step-by-step explanation:
Amount invested = $1000
Total interest income over the course of 3 years = $120
Number of years = 3
Annual interest income = Total interest income over the course of 3 years / Number of years = $120 / 3 = $40
The interest ate on the $1000 invested can now be calculated as follows:
Interest rate = (Annual interest income / Amount invested) * 100 = ($40 / $1000) * 100 = 0.04 * 100 = 4%
Therefore, the rate at which the $1000 is invested is 4%.
Since the answer is required to be written without the percent sign, it therefore implies that he rate at which the $1000 is invested is 4.

Write the equation of the parabola with a focus at (-3, -5) and a directrix at y = -7.
Answer:
The directrix is negative so the equation will be
x^2=4ay
x=-3
y=-5
a=x^2/4y
a=(-3)^2 /4*(-5)
a=9/20
x^2=4*(9/20)*y
x^2=9/5y
Step-by-step explanation:
The directrix always determine the equation to use. It is also important to notice the sign(-+).
rearrange y=4-3x/x-5 to make x the subject
Answer:
x = [tex]\frac{4+5y}{y+3}[/tex]
Step-by-step explanation:
Given
y = [tex]\frac{4-3x}{x-5}[/tex] ( multiply both sides by x - 5
y(x - 5) = 4 - 3x ( distribute left side )
xy - 5y = 4 - 3x ( add 3x to both sides )
xy + 3x - 5y = 4 ( add 5y to both sides )
xy + 3x = 4 + 5y ← factor out x from each term on the left side
x(y + 3) = 4 + 5y ← divide both sides by y + 3
x = [tex]\frac{4+5y}{y+3}[/tex]

Determine the best method to solve the system of equations. x = 2y – 1 3x + y = 11
Please answer the best you can. Thanks
Answer:
Subsitution
Step-by-step explanation:
We have the equations:
x=2y-1
3x+y=11
The 3 methods of solving systems of equations are:
graphing
substitution
addition/elimination
Graphing involves graphing the two equations and finding their point of intersection, which is the answer
Substitution involves isolating one of the variables in one of the equations, then substituting the resulting expression into the other equation to find both numbers
Addition/Elimination involves adding the two equations together to clear a variable, solving for the other variable, and substituting the answer to the first variable in one of the equations to find the value of the cleared variable from before
Since we have x already isolated onto one side in the first expression, we can easily substitute it as 2y-1 in the second equation.
Therefore, substitution is the best method to solve this graph.

21/8
Step-by-step explanation:
KCF or keep change flip. keep 7/8. turn divide into multiply, then flip 1/3 to 3/1. 21/8 is what you get. Hope this helped!
Answer:
21/8
Step-by-step explanation:
Dividing by a fraction is like multiplying with the inverse:
So (7/8) / (1/3)
is the same as
(7/8) * (3/1) = (7/8) * 3 = 21/8
21/8 cannot be simplified, unless you find 2 5/8 simpler

Rene has a $50 gift card from a local coffee shop. Each day, he buys the same latte which costs $4.25. When will he have $11.75 left on his card?
Answer:
50-4.25x=11.75
Step-by-step explanation:
So first rene has 50 dollars and has 11.75 left eventually, so that indicates this is a subtraction problem. Also Rene buys a latte cost 4.25 dollars for a certain amount of days so let x represent amount of days and your equation should be 50-4.25x=11.75

ok so
the triangle has 3 angle
45-45-90
one 45 points to x
that means the other side is also x
the 90 degrees points to 3
3=x√2
x=2.12132
The value of x in the given diagram is 3√2, Option C is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle has 45-45-90 degrees.
We have to find the value of x in the given triangle.
The cosine function is ratio of the adjacent side by hypotenuse.
cos 45= 3/x
The value of cos 45 degrees is one divided by root 2.
1/√2 =3/x
Now apply the cross multiplication
x=3√2
Hence, the value of x in the given diagram is 3√2, Option C is correct.
