Answer:
a.) Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )
b.) Total amount spent by Maria = $ 74.02
Step-by-step explanation:
As given,
Cost of gasoline = $ 3.95 gallon
Cost of oil per can = $ 4.45
Also given,
Maria bought g gallons of gasoline and c cans of oil
⇒ Total cost of g gallons of gasoline = g×3.95 = $3.95g
Total cost of c cans of oil = c×4.45 = $4.45c
Now,
a.)
Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )
b.)
As given ,
Maria buy gasoline , g = 8.6 gallons
Maria buy cans of oil , c = 6
So,
Total amount spent = $ 3.95(8.6) + 4.45(9)
= $ 33.97 + 40.05 = $ 74.02
⇒Total amount spent by Maria = $ 74.02

You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
Answer:
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 =

Margie has 5 times as many nickels as quarters. She has a total of $2.00.
Part (a) Write a system of equations to represent the situation. Let n represent the number of nickels and q represent the number of quarters.
Part (b) Solve the system you wrote in part (a). Show your work.
Part (c) Interpret your solution in the context of the problem.
P.S. Sorry for asking so many questions, I swear this will be the last one for a while.
The only thing I really need help with is Part A, writing the equations.
Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200

Answer:
x= 64.3
Step-by-step explanation:
To solve for x, you have to use trig. Since you're solving for an angle, you use inverse trig.
the problem gives you your opposite(29) and your adjacent(14), so you will use tangent.
so to set up your equation to type it into your calculator, it will be
[tex]tan^{-1} (\frac{29}{14} )[/tex]
type this into your calculator and you will get x.

ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)

A store offers a 30% discount on a clarinet that was marked up by 5% form the original retail price for $405.the sales tax is 9%. What does the clarinet cost?.
Answer:
$324.46
Step-by-step explanation:
$405 × 0.05= $20.25 is how much it is marked up if the original price is $405.
$405 +$ 20.25 = $425.25 is the new total of the clarinet
Now 30 % of $425.25... $425.25×0.30= $127.58 is what 30% is.
You have to subtract th $127.58 from $425.25 to get the discounted price.
$425.25 - $127.58 = $297.67
Next you have to calculate for the 9% and add it to the discounted price.
$297.67 × .09 = $26.79
$297.67 + $26.79= $324.46
$324.46 is the cost of the clarinet.

As a retiring employee, you'll receive 5.96% of your average salary from the last five years you worked with your company.
You plan to retire after 37 years with the company.
Your salaries for your last five years are:
$180,267
$210,325
$126,591
$77,184
$173,175
Calculate your annual retirement salary.
Answer:
9,149.10
Step-by-step explanation:
To get the average you take all the values and add them up then divide by 5.
767,542 divided by 5 = 153,508.40
Now to get the percentage take 5.96 and divide by 100 = 0.0596
With this you can multiple the average by the percent in decimal form.
153,508.40 * 0.0596 = 9,149.10

Total profit P is defined as total revenue R minus total cost C, and is given by the function P(x)=R(x)−C(x). Find the total profit P(x) when R(x)=126.98x−0.5x2 and C(x)=3809.40+0.7x2.
Given:
The revenue function is
[tex]R(x)=126.98x-0.5x^2[/tex]
The cost function is
[tex]C(x)=3809.40+0.7x^2[/tex]
To find:
The profit function.
Solution:
We know that, the total profit P is defined as total revenue R minus total cost C.
So, the profit function is
[tex]P(x)=R(x)-C(x)[/tex]
[tex]P(x)=126.98x-0.5x^2-(3809.40+0.7x^2)[/tex]
[tex]P(x)=126.98x-0.5x^2-3809.40-0.7x^2[/tex]
[tex]P(x)=-3682.42-1.2x^2[/tex]
Therefore, the profit function is [tex]P(x)=-3682.42-1.2x^2[/tex].

O D. There are infinitely many solutions.
Answer:
C. x=-2
Step-by-step explanation:
To solve use PEMDAS,
First, distribute
6-x=20+4x-4
Then, combine like terms
6-x=16+4x
Add x to both sides
6=16+5x

K is between P and Q. Suppose PQ- 10x - 16, PK - 6x + 8, and KQ-8. What is PQ?
Answer:
PQ = 64
Step-by-step explanation:
PQ = PK + KQ
10x - 16 = 6x + 8 + 8
10x - 16 = 6x + 16
4x = 32
x = 8
PQ = 10(8) - 16
= 80 - 16

Given the graph, determine whether (a)the degree is even or odd and (b) the leading coefficient is positive or negative
Answer:
A. Odd
B. Positive Leading Coefficient
Step-by-step explanation:
When it comes to degree - Odd degrees start from below the x axis and end over the y axis
For leading coefficients - Positive leading coeffcients always start from below, since we know the degree is odd, this leading coefficient fit.

Describe the graph of the equation y = 0. Is the equation a function?
vertical line; yes
horizontal line; yes
vertical line; no
horizontal line; no
Answer: B. horizontal line; yes
Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:
(0,0)
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Step-by-step explanation: A. vertical line; yes
horizontal line; yes
Yes! Horizontal line represents a function y = f(x)
(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.
(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y
C. vertical line; no
