Malik bought a pack of erasers for $3.50 and some pencils for $0.99 each. He paid a total of $10.43. Which equation can be used to find the number of pencils Andrew bought? \
Answer:
The equation that can be used to find the number of pencils Andrew bought is:
x=(c-3.50)/0.99
Step-by-step explanation:
With the information provided, you can say that the total amount paid would be equal to the price of the pack of erasers plus the price per pencil for the number of pencils purchased, which can be expressed as:
c=3.50+0.99x, where:
c is the total cost
x is he number of pencils purchased
Now, you can solve for x in order to find the equation to calculate the number of pencils Andrew bought:
c-3.50=0.99x
x=(c-3.50)/0.99
According to this, the answer is that the equation that can be used to find the number of pencils Andrew bought is:
x=(c-3.50)/0.99

10x – 2y = 18
-10x + 9y = -46
Answer:
x=1, y=-4. (1, -4).
Step-by-step explanation:
10x-2y=18
-10x+9y=-46
------------------
7y=-28
y=-28/7
y=-4
10x-2(-4)=18

You invest $500 in an account that pays 6% interest compounded continuously. How
much will be in the account after 6 years?
=====================================================
Explanation:
We'll apply this formula
A = P*e^(r*t)
where,
A = account balance after t yearsP = initial deposit, aka principale = special constant roughly equal to 2.718 but it goes on forever without a pattern; it's better to let the calculator handle this value rather than type the decimal digits in.r = annual interest rate in decimal formt = number of yearsIn this case, we have
P = 500r = 0.06t = 6Again we won't type "2.718..." for 'e', and we'll just type it into the calculator as shown below. That way the calculator can handle the digits instead.
So...
A = P*e^(r*t)
A = 500*e^(0.06*6)
A = 716.66470728026
A = 716.66 dollars is the final answer
Find the volume, in cubic inches, of a right rectangular prism with the measurements below. Length: 3/2" Width: 5/2" Height: 4
Answer:
Step-by-step explanation:
The volume of a rectangular prism can be calculated by multiplying the area of its base by its height.
Mathematically, we have
The volume of prism = base area X height
At this point, it is important to note that a rectangular prism is a solid shape that has its base as a rectangle; so the area of its base, is the same thing as the area of a rectangle.
Where base area = length X breadth
hence, volume = length X breadth X height
volume = 3/2 X 5/2 X 4 = 15 cubic inches
Let x and y be inversely related. If x is 5 when y
is 6, find y when x is 3.
Answer:
y=10
Step-by-step explanation:
x=k/y
constant of proportionality
k=xy
k=5*6
k=30
therefore x=30/y
if x=3 y=?
y=30/3
y= 10

write an equation for a function that has vertical asymptotes at x=3 & x=-10
Answer:
[tex] \frac{5}{ {x}^{2} + 7x - 30} [/tex]
Step-by-step explanation:
We can write a rational function.
We need to make sure our denominator both have zeroes at 3 and 10.
Set an equation equal to zero to find the function
[tex]0 - x = 3[/tex]
[tex]0 - x = - 10[/tex]
[tex]0 - ( - 3) = = 3[/tex]
[tex]0 - 10 = 10[/tex]
So we would represent that's as
[tex]x - 3[/tex]
and
[tex]x + 10[/tex]
Multiply the two binomial together.
[tex](x - 3)(x + 10) = {x}^{2} + 7x - 30[/tex]
Let our numbetator be any interger.
Use any equation as long as the quadratic is the denominator and the interger is the numerator.
[tex] \frac{5}{ {x}^{2} + 7x - 30 } [/tex]

What is the surface area?
Answer:
The total area is 685
Step-by-step explanation:
First get the area of the square; the area of the square is the height times the width. Because its a square all of its sides are equal, 15 times 15 equals 225. Next we go to figuring out the triangles´ area; the formula to figure out a triangles area is 0.5 times height times width. Because there are 4 of the exact same triangles we only have to figure out one and we have the area for each of them. 0.5 times 20 times 15 equals 115, with that information we are able to obtain all the information we need to discover the total area.
The area of the square: 225
The area of each of the triangles: 115
If there are 4 exact triangles of 115 then that equals all the triangles together to be 460, then add the square 460 plus 225 equals 685.
Hope this helps!!

The scatter plot shows the number of hours worked and money soent on etnertainment by each of 25 students . Also shown is tbe ljne of best fit for the data fill in the blanks below
Answer:
Follows are the responses to the given question:
Step-by-step explanation:
Please find the attached file for the complete question:
For point A:
The amount of money being spent appears to rise for those 25 students as the number of hours increases. This is evident from the plot of scattering as well as the best line.
For point B:
Its number of hours spent as well as the amount of money spent were also positive for such 25 students.
For point C:
Also with a line that fits best, we will indeed predict that only an 8-hour student would spend about $22.
All these are seen in a direct line drawn from the x-axis where x=8 fits this same best line and a horizontal line is drawn between that axis and the Y-axis is drawn.

Given our equation: [tex]x^2+5x+3 = 0[/tex]
a = 1b = 5c = 3Plug it into the formula and solve:
[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-5\pm\sqrt{5^2 - 4(1)(3)}}{2(1)}[/tex][tex]x = \frac{-5\pm\sqrt{25-12}}{2}[/tex][tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex]This cannot be simplified further. The answer is [tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex].
