Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.60 plus $0.75 per mile. The total fare was $8.35, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride.
Answer:
1.60+0.75x=8.35
x=9
Step-by-step explanation:
1.60+0.75x=8.35 will be the equation to determine the number of miles x.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Pickup charge (fixed charge) = $4.60
Charge per mile = $0.75 /mile
Total charge = $8.35
So,
Total charge = pick up charge + Charge per mile × number of mile(x)
8.3.5 = 1.60 + 0.75x
1.60+0.75x=8.35
Hence "1.60+0.75x=8.35 will be the equation to determine the number of miles x".

Which set of rectangular coordinates describes the same location as the polar coordinates (4,pi)?
A. (0,-4)
B. (-4,0)
C. (0,4)
D. (4,0)
The rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)
The polar coordinate is given as:
[tex]\mathbf{(4,\pi)}[/tex]
To represent the polar coordinates properly, we make use of:
[tex]\mathbf{(r,\theta) = (4,\pi)}[/tex]
Where r represents radius
The rectangular coordinate is represented as: (x,y)
Where:
[tex]\mathbf{x = rcos(\theta)}[/tex]
[tex]\mathbf{y = rsin(\theta)}[/tex]
So, we have:
[tex]\mathbf{x = 4 \times cos(\pi)}[/tex]
Evaluate cos(pi)
[tex]\mathbf{x = 4 \times -1}[/tex]
Multiply
[tex]\mathbf{x = -4}[/tex]
Similarly,
[tex]\mathbf{y = 4 \times sin(\pi)}[/tex]
Evaluate sin(pi)
[tex]\mathbf{y = 4 \times 0}[/tex]
Multiply
[tex]\mathbf{y = 0}[/tex]
Recall that the rectangular coordinate is represented as (x,y)
Hence, the rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)

A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies. You pick one candy at random. Find the probability it is purple or not red.
Answer: there is a 53.24 percent chance.
Step-by-step explanation: Add all of the candies and get 139. Then add 32 and 42 to get 74. Then subtract 74 from 139 and get 65. Finally, you find the percentage of 74/139 and get 53.24.
if f(x) = 3x+2, what is f(5)
Answer:
f(5) = 17
Step-by-step explanation:
Function: f(x) = 3x + 2
x-value: 5
Equation: f(5) = 3(5) + 2
Solve:
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
Warning⚠Many people thin that something like f(x) means that you are multiplying f and x. This is incorrect.
f(x) = 3x + 2 is the same as y = 3x + 2, the f is the name of the function, and you replace a number, like 5, for the x - value.

A survey found that women heights are normally distributed with mean 63.6 in and standard deviation 2.5 in. A branch of military requires women heights to be between 58 in and 80 in
Answer:
See below:)
Step-by-step explanation:
a)
mean = 63.6 , s.d = 2.5. We need to compute Pr(58 <= X <= 80)
The corresponding z-values needed to be computed
z1 = (58 - 63.6)/2.5 = -2.24
z2 = (80 - 63.6)/2.5 = 6.56
Therefore, we get:
Pr(58 <= X <= 80) = Pr( (58 - 63.6)/2.5 <= Z <= (80-63.6)/2.5 ) = Pr(-2.24 <= Z <= 6.56)
= 1 - 0.0125 = 0.9875
98.75 % of the women meet the requirements,Hence not too many women are being denied the opportunity to join this branch of the millitary.
b)
z value for lower 1% = -2.3263
corresponding x value = 63.6 - (2.5X2.3263) = 57.78
Z value for upper 2% = 2.0537
corresponding x value = 63.6 + (2.5X2.0537) = 68.73
The new height requirements is between 57.78 and 68.73 inch

Ron can run a mile in 12 minutes. It takes his
younger brother, Sam, 1.5 times longer to run a mile.
How long does it take Sam to run a mile?
Answer:
18 minutes to run a mile
Step-by-step explanation:
1.5 is equal to 150%. so given that you have 12 minutes you can do what is 150% to 12 so 100% of 12 is 12 and 50% of 12 is 6 and 6 + 12 is 18

Write an exponential equation?
Answer:
[tex]y = 3^{-x-2}[/tex]
Step-by-step explanation:
Since the graph is exponential, the default form of formula is going to be:
y = aˣ;
First question is, what information do we have?
I can see 3 distinct points: (2, 1), (1, 3) and (0, 9);
Normal exponential curve have a positive gradient at every point, increasing as you proceed along the x-axis to ∞;
The opposite is true of the graph in the image which tells us it is reflected in the y-axis as compared to a default exponential graph;
Any exponential function will have the point (0, 1);
Considering we have (2, 1), there seems to be a translation of 2 units rightwards;
Then considering the pattern of the y-values of the points identified above, which is 1, 3 and 9;
3⁰ = 1, 3¹ = 3 and 3² = 9;
This suggests a = 3;
We then combine this like so:
So, if we start with f(x) = 3ˣ
Then we need to apply the transformations identified above in the order of stretching, then reflections and finally translations;
Applying the reflection first;
[tex]g(x) = f(-x) = 3^{-x}[/tex]
Then, the translation of 2 units rightwards like so;
[tex]g(x-2) = 3^{-(x-2)}[/tex]
There is no apparent stretching, there could be, but, we don't know so, best thing to do is to test what we have thus far and check if it matches the graph in the image;
So, we end up with:
[tex]y = 3^{-x-2}[/tex]
Now, to test this;
Let x = 0, then:
[tex]y = 3^{-(0)+2} \\\\ y = 3^{2} \\\\ y = 9[/tex]
This matches (0, 9);
Similarly, when x = 1, then y = 3;
And x = 2, then y = 1;
This matches the graph, so this seems to be the equation of the graph.

Rosie is making a special green paint it contains 2/3 cups yellow paint 1/3 cups white paint 1 and 1/5 blue paint and 1/5 black paint what percentage of the green paint is blue
Answer:
50%
Step-by-step explanation:
total cups to make green paint: 36/15
total cups of blue paint in green paint: 18/15
18/15 is what % of 36/15
(18/15) ÷ (36/15) = x÷100
the above proportion can be simplified to be:
(6/5) ÷ (12/5) = x÷100
cross-multiply to get:
(12/5)x = 600/5
x = (600/5) · (5/12)
x = 50
