A person has 28 coins, all dimes and quarters, worth $4.60. How many quarters are there?
16
18
12
Remember that a dime is worth 10 cents and a quarter is worth 25 cents and $4.60 is 460 cents.
Let D = the number of dimes and Q = the number of quarters.
Now let's translate the English into math. . .
there are 28 coins in all--> D + Q = 28 so D = 28 - Q
they are worth 460 cents--> 10D + 25Q = 460
Now substitute 28-Q for D--> 10(28-Q) + 25Q = 460
280 - 10Q + 25Q = 460
Combine like term. . .
15Q = 180
Divide both sides by 15--> Q = 12
So D = 16
Answer:
12
Step-by-step explanation:
D=dimes Q=quarters
D+Q=28 so D=28-Q
460=10D+25Q
substitute 28Q for D
10(28-Q)+25Q=460
280-10Q+25Q=460
combine like terms
15Q=180
divide both sides by 15 so Q= 12 and D=16

A cashier checks the price of a hockey stick that is marked $44, because it usually rings up at $80. What is the discount percentage?
Answer:
The discount percentage is 45%.
Step-by-step explanation:
To be able to determine the discount percentage, you can use the following formula:
Discount percentage=(final price-original price/original price)*100
Original price=80
Final price=44
Now, you can replace the values in the formula:
Discount percentage=(44-80/80)*100
Discount percentage=-45%
According to this, the answer is that the discount percentage is 45%.
The number of ducks, D, (in thousands) and geese, G, (in thousands) that migrate from 1980 to 2000 can be modeled by the equations:
D = -120 + 294.1t - 184.4t + 50.2t3, 1 < t < 21
G = -188 + 579.6t - 403.3t + 97.8t3, 1 < t < 21
Where t represents the year, with t = 1 corresponding to 1980.
a) Find a radical expression that models the total number, T, of birds that migrated from 1980 to 2000.
T = -68 + 873.7t - 218.9t + 148tt
T = -308 + 1021tt - 587.7t
T = -68 + 285.5t - 218.9t + 47.6tt
T = -308 + 873.7t - 587.7t + 148tt

Damian has a rectangular photo frame. The length of the photo frame is 30 inches, and the width of the frame is 16 1/4 inches. What is the length of the diagonal of this frame in inches?
Answer:
I think it's 34.12 inches
Step-by-step explanation:
Use the Phythagorean Theorem, because bisecting a rectangle using the diagonal will produce 2 triangles. The diagonal represents the hypotenuse of the triangle so to solve for it you'd use the formula c² = a²+b²

In which quadrant does θ lie given that sinθ > 0 and cos θ < 0
The quadrant in which the angle θ lies when sin θ > 0 and cos θ < 0 will be

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
In the first quadrant, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sin is positive.
In the third quadrant going anti-clockwise, only tan is positive.
In the fourth quadrant going anti-clockwise, only cos is positive
Given data ,
Let the angle be θ
Now , the sin of the angle θ is positive and cos of the angle θ is negative
The equation is given as
sin θ > 0 and cos θ < 0
And , from the trigonometric relations , we know that
In the first quadrant, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sin is positive.
In the third quadrant going anti-clockwise, only tan is positive.
In the fourth quadrant going anti-clockwise, only cos is positive
So , in the second quadrant only sin is positive and all the other trigonometric relations are negative
Therefore , the quadrant where sin θ > 0 and cos θ < 0 will be in the second quadrant
Hence , The quadrant in which the angle θ lies when sin θ > 0 and
cos θ < 0 will be in the second quadrant

For the function (x) = -3x+8, determine x when f(x) = -25
Answer:
83
Step-by-step explanation:
f(x)= -3(-25)+8=83
The value of the variable is "x = 11" when f(x) = -25 for the given function f(x) = -3x+8.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
To determine x when f(x) = -25 for the function f(x) = -3x+8, you will need to solve the equation -3x+8 = -25 for x.
To do this, you can follow these steps:
Begin by isolating the x term on one side of the equation. To do this, you can add 3x to both sides of the equation to get -3x+3x+8 = -25+3x.
Simplify the left side of the equation by combining like terms to get 8 = -25+3x.
Subtract 8 from both sides of the equation to get 0 = -25+3x - 8.
Add 25 to both sides of the equation to get 33 = 3x.
Divide both sides of the equation by 3 to get x = 33/3 = 11.
Therefore, x = 11 when f(x) = -25 for the function f(x) = -3x+8.
