Simplifying
e = 9
Answer:9
Step-by-step explanation:
A women buys a coat through the mail for $250 plus 9% sale tax. If another 10% is added onto this total for shipping and handling, what is the total cost of the coat ?
Answer:
Find 9% of 250 by turning 9% into a decimal.
.09 x 250 gives you 22.50
add 22.50 to 250
now you have 272.50
now find 10% of 272.50 by converting 10% into a decimal.
.10 x 272.50 gives you 27.25
Add that to 272.50 and you total cost is
$299.75
Kala is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges $ 79 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.70 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer: 21 miles
Step-by-step explanation:
Emma buys 9 bottles of pineapple juice at the corner store for a total cost of $10.62.
Assume each bottle of juice is the same price. If c represents the total cost in dollars
and cents of the juice for any number, j, of bottles of juice, write a proportional
equation for c in terms of j that matches the context.
$1.18
Step by step explanation :
9c = 10.62
c = 10.62/9
c = 1.18
Find the slope of the tangent line to the given polar curve at the point specified by the value of θ
r = 9 + 8 cos(θ), θ = π/3
The given curve has equation
r(θ) = 9 + 8 cos(θ)
and its derivative is
dr/dθ = -8 sin(θ)
When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.
Differentiate these with respect to θ :
dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)
dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)
In polar coordinates, we have
y(θ) = r(θ) sin(θ)
x(θ) = r(θ) cos(θ)
and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.
The slope of the tangent line to the curve is dy/dx. By the chain rule,
dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)
dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))
When θ = π/3, the slope is
dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))
dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))
dy/dx = - 1/(17√3)
So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is
y - 13√3/2 = -1/(17√3) (x - 13/2)
y = -(x - 338)/(17√3)

What is the conditional statement?A conditional statement is defined as the two fundamental components that make up a conditional statement are Hypothesis (if) and Conclusion (then).
Let us consider the example to understand the parts of a conditional statement.
Conditional Statement: If today is Friday, then yesterday was Thursday.
Hypothesis: "If today is Friday."
In the given problem,
Conditional Statement: If p → q and q are true, then p is true,
Hypothesis: "If p → q and q are true"
Hence, the statement that If p → q and q are true, then p is true which is the correct answer would be option (A)

Hello everyone i need ur help to factor out this in a easy way.
9514 1404 393
Answer:
(x -1/4)(x -1)(x +1)
Step-by-step explanation:
Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.
x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs
= x(x² -1) -1/4(x² -1)
= (x -1/4)(x² -1)
The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)
Your factoring is ...
(x -1/4)(x -1)(x +1)
_____
Additional comment
The difference of squares factors like this:
a² -b² = (a -b)(a +b)
For a corporation that has 2,500,000 shares of stock, how may shares would be needed to be a majority stock holder ? *
Step-by-step explanation:
a majority starts at half of the total mass + 1.
so,
2,500,000 / 2 = 1,250,000
and + 1 means then the majority would be
1,250,001 shares.

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km
How to find Length of Similar Triangles?We are given a Triangle PQR.
In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.
In Triangle SRT, Side RT = 33 kilometers.
Using concept of ratio of similar triangles, we can say that;
ST/RT = PQ/PR
Thus;
ST = RT * (PQ/PR)
ST = 33 * (16/24)
ST = 22 Km
