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

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

Step-by-step explanation:
75 + 45 + y = 180
120 + y = 180
y = 60
60 + 79 + z = 180
z + 139 = 180
z = 41
41 + 68 + a = 180
109 + a = 180
a = 71
x + a = 180

What single percentage change is equivalent to a 17% increase followed by a 8% decrease?
Answer:
9% increase
Step-by-step explanation:
Given :
17% increase :
Let initial percentage = 100%
17% increase means :
100% + 17% = 117%
Followed by 8% decrease :
117% - 8% = 109%
Hence, the final percentage = 109%
To represent the total change as a single percentage change :
Change = final percentage - Initial percentage
Change = 109% - 100%
Change = 9%
This is a 9% increase

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%.

Answer:
4) 120π cm^2
5) 56π cm^2
6) 32π cm^2
Step-by-step explanation:
Surface Area of Cylinder = 2π[tex]r^{2}[/tex] + (2πr)(height)
(will use variable h for height)
4)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 11 cm
2π[tex]4^{2}[/tex] + (2π)(4)(11)
= 2π(16) + 2π(44)
= 32π + 88π
= 120π cm^2
5)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 6 cm
2π[tex]4^{2}[/tex] + (2π)(4)(6)
= 2π(16) + 2π(12)
= 32π + 24π
= 56π cm^2
6)
diameter = 6 cm
r = 0.5(diameter) = 0.5(6) = 3 cm
height = 7 cm
2π[tex]3^{2}[/tex] + (2π)(3)(7)
= 2π(9) + 2π(7)
= 18π + 14π
= 32π cm^2

Ann took a taxi home from the airport. The taxi fare was $2.10 point, 10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10,
Answer: 21 miles
Step-by-step explanation:
Here's the remainder of the question:
Write an equation to determine the distance in miles x between the airport and Ann's home.
We are informed that the taxi fare was $2.10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10, this can be expressed into an equation as:
(2.10 × x) + 5 = 49.10
2.10x + 5 = 49.10
2.10x = 49.10 - 5
2.10x = 44.10
x = 44.10 / 2.10
x = 21
The distance between the airport and Ann's home is 21 miles.

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
in the second quadrant
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.
