Elizabeth purchased a $20 bus pass. Each time she rides the bus $1.25 is deducted from the pass. What equation would represent this scenario? *
12 points
y= 1.25x - 20
y= -1.25x + 20
y= 20x - 1.25
y= 20x + 1.25
Answer:
Y = 1.25x - 20
Step-by-step explanation:
Everytime she rides the bus 1.25 is taken away from that 20.
The x = Every ride
For example
say she rode the bus 5 times so it would be
1.25 × 5 = 6.25 now you take the answer and subtract it from the 20
20 - 6.25 = 13.75
I hope this helped :)

Answer:
D = 31
Step-by-step explanation:
Consider the equation showing the distributive property.
84 +93 = 3 (28+ D)
The unknown value we are asked to find is D
Hence:
84 + 93 = 84 + 3D
Collect like terms
84 - 84 + 93 = 3D
93 = 3D
D = 93/3
D = 31
Therefore, the unknown value that would make the equation true is 31

In terms of the water lily population change, the value 3.915 represents:
Answer:
he initial number of water lily’s :the value 1.106 represents the population increase rateedge
Step-by-step explanation:
The value 3.915 represents the initial population in the exponential equation of water lilies.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
There usual form is specified below. They are written in several such equivalent forms.
The standard exponential equation is given as; y = ab^x
where;a is the initial population b is the rate (growth or decline)
We have been Given the exponential equation; y = 3.915(1.106^x)
On comparison, we can see that,
a = 3. 915
Hence, This shows that the value 3.915 represents the initial population of water lilies.

This circle has a radius of 12 millimeters and is divided into 8 equal sections. In terms of pi,
what is the area of 1 section of this circle?
Answer:
A = 18π mm²Step-by-step explanation:
Area of a circle: [tex]A_\circ =\pi r^2[/tex] where r is a radius of this circle
8 equal section means area of one is: [tex]A=\dfrac{\pi r^2}{8\ }[/tex]
r = 12 mm

If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current
Answer:
1.9 Amps
Step-by-step explanation:
In an RC circuit, the relationship between the current I in amps, the impedance Z in ohms and the voltage V in volts may be stated as
V = IZ
As such, given that z = 52.5 ohms and V = 100 Volts, the current in the circuit I may be computed as
100 = I * 52.5
Divide both sides by 52.5
I = 100/52.5
= 1.9 Amps

Stephanie took advantage of the interest-only financing from Rooms-To-Go and borrowed $2,000 with a 15 percent annual interest rate. How much will she have paid in interest after 8 months?
Answer: $200
Step-by-step explanation
Principal = $2000
Rate = 15%
Time = 8 months = 8/12 = 2/3 years
Interest = Principal × Rate × Time
= 2000 × 15% × 2/3
= 2000 × 15/100 × 2/3
= $200
The interest is $200

an isosceles right triangle has an area 8 cm square find the length of its hypotenuse
please answer me fast
Answer:
5.9
Step-by-step explanation:
Area of a triangle is 1/2 base times height. the base is the horizontal part of the triangle and the height is the vertical part. Since it a isosceles they are equal. Those two segment are also called the legs (remember that for later). 4x4=16 times 1/2 equal 8 cm squared. So know me must find the hypotenuse. Since we since dealing with a right triangle we are going to use pythagorean theorem which is
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
where a and b are the LEGS and c is the hypotenuse. the legs are also known as base and height so we use
[tex] {4}^{2} + {4}^{2} = {c}^{2} [/tex]
which simplify to
[tex]16 + 16 = {c}^{2} [/tex]
[tex]32 = {c}^{2} [/tex]
[tex] \sqrt{32} [/tex]

One of the roots of equation x^(2)-(3p-4)x+11p-5=0 is 8. Find the other root. Find the value of p.
Answer:
Other root is 9 and p = 7.
Step-by-step explanation:
x^(2) - (3p-4)x + 11p-5 = 0 , x = 8.
Let the other root be A, then using the formula for the product and sum of the roots of a quadratic equation:
8* A = 11p - 5
8 + A = -(-(3p - 4))
8 + A = -(-3p + 4)
8 + A = 3p - 4
A = 3p - 12.
Multiply this last equation by 8:
8A = 24p - 96
Now subtract the first equation from this:
8A - 8A = 24p - 11p - 96- (-5)
0 = 13p - 91
13p - 91 = 0
p = 91/13 = 7
and A = 3(7) - 12
= 9.
Answer:
Other root 9, p is 7

write the indicated trig ratio as a fraction
Sin K =
72 millimeters to 3 meters
The ratio is 24:1000 or 0.024.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
72 millimeters to 3 meters
Now, Convert 3 meter to millimeter
3 meter= 3 x 1000
= 3000 mm
Then, ratio is
= 72 / 3000
= 24/1000
= 0.024
