Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?
Answer:
$35
Step-by-step explanation:
first we need to find the amount of money the sweaters cost alone.
so we first subtract the total (160) - the skirt price (20) which is 140
now we divide it by 4 to find the price of each seater, as they all cost the same.
so 140 divided by 4 = 35
answer: $35

A tank is in the shape of a cylinder 7 feet tall and 10 feet and radius find the exact surface area of the tank
Answer:
[tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : [tex]\pi 10^{2}[/tex] = 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :2[tex]\pi[/tex]10 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = [tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth

Step-by-step explanation:
Find two linear functions p(x) and q(x) such that (p (f(q(x)))) (x) = x^2 for any x is a member of R?
Let p(x)=kpx+dp and q(x)=kqx+dq than
f(q(x))=−2(kqx+dq)2+3(kqx+dq)−7=−2(kqx)2−4kqx−2d2q+3kqx+3dq−7=−2(kqx)2−kqx−2d2q+3dq−7
p(f(q(x))=−2kp(kqx)2−kpkqx−2kpd2p+3kpdq−7
(p(f(q(x)))(x)=−2kpk2qx3−kpkqx2−x(2kpd2p−3kpdq+7)
So you want:
−2kpk2q=0
and
kpkq=−1
and
2kpd2p−3kpdq+7=0
Now I amfraid this doesn’t work as −2kpk2q=0 that either kp or kq is zero but than their product can’t be anything but 0 not −1 .
Answer: there are no such linear functions.

What’s the rise over run pleas???
9514 1404 393
Answer:
-1/5
Step-by-step explanation:
To find the ratio of rise to run on a graph, it is convenient to start by looking for points where the graph crosses the intersection of grid lines. This lets you read the exact coordinates of the points, without any guessing.
In the attachment, the grid crossings we chose are circled.
The "rise" is the vertical distance between the points. If the right point is lower, the "rise" is negative.
The "run" is the horizontal distance between the points.
The reason for choosing grid crossings is that it then becomes fairly easy to count the grid lines between the points, vertically and horizontally.
On this graph, the "rise" is -1 for a "run" of 5. Then the slope, or ratio of rise to run, is ...
m = rise/run = -1/5 . . . . . . slope of the line

The table shows information about the population of a city.
Population in 2001 is 420 000
Population in 2011 is 480 000
Liam claims
"From 2011 to 2021 the population of the city will increase by
the same percentage as from 2001 to 2011"
He works out.
population increase from 2001 to 2011 = 480 000 - 420 000
= 60 000
population in 2021 = 480 000 + 60 000
= 540 000
Does the population of 540 000 match his claim?

Answer:
[tex]y=-0.3(x-2)^2+2[/tex]
Step-by-step explanation:
We know that the parabola faces downard, and hence must have a negative first term, so that eliminates the first and third options.
The vertex of the parabola has an x-value of 2, so it must be of the form [tex]a(x-3)^2+c[/tex].
Combining these, we have that the answer is [tex]\boxed{y=-0.3(x-2)^2+2}[/tex]
Solve for P A= 2xP+4P
Answer: P = A/6
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
How to determine values of a,b and c
(i) The graph of f is symmetric about the y-axis - this is another way of saying f is an even function, which means
[tex]f(x) = f(-x) \iff \dfrac{ax+b}{x^2-c} = \dfrac{-ax+b}{x^2-c}[/tex]
The denominator remains unchanged, so
ax + b = -ax + b
Solve for a :
ax = -ax
2ax = 0
a = 0
(The alternative is that x = 0, but if that were the case then there would be infinitely many choices for a.)
So
[tex]f(x) = \dfrac{b}{x^2-c}[/tex]
(ii) Since
[tex]\displaystyle \lim_{x\to2^+}f(x) = +\infty[/tex]
it follows that x - 2 must be a factor of the denominator. If that's true, then
x ² - c = (x - 2) (x - r )
for some other root r of x ² - c. Expanding the right side gives
x ² - c = x ² - (2 + r )x + 2r
so that
-(2 + r ) = 0 ===> r = -2
2r = -c ===> -c = -4 ===> c = 4
and so
[tex]f(x) = \dfrac{b}{x^2-4}[/tex]
(iii) Finally, we're given that f ' (1) = -2. Differentiating f gives
[tex]f'(x) = -\dfrac{2bx}{(x^2-4)^2}[/tex]
so that
[tex]f'(1) = -\dfrac{2b}{(1^2-4)^2} = -\dfrac{2b}{9}[/tex]
Then
-2b/9 = -2 ===> b = 9
and we find that
[tex]f(x) = \dfrac{9}{x^2-4}[/tex]

A car is 150 inches long. A truck is 60% longer than the car.
How long is the truck?
Answer: Therefore, the truck is 240 inches long.
Step-by-step explanation:
truck = 150 + 60% of 150
= 150 + 60/100 * 150
= 150+90
= 240 inches

Hamish buys a new car for 520000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $.
Answer:
$223,600
Step-by-step explanation:
1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.
2. Now multiply 98800 by 3 (years). Now your answer would be 296400.
3. Now minus the depreciated value from the original value which is 520000-296400=223600.
Not sure about the answer but I hope this helped a bit
Answer:
$3,567.00
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 520,000 from the word problem.
Next, multiply 520,000 with 0.19 with the power of 3
[tex]520,000*0.19^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.19^3[/tex]
[tex]0.19*0.19*0.19=0.006859[/tex]
(Again, that's a crazy number!)
--
With 0.006859, multiply it with 520,000
[tex]520,000*0.006859=3566.68[/tex]
3566.68 is technically (in money) $3,566.68 (with .68 being sixty-eight cents).
--
Finally, it states to answer to the nearest $.
Just round up the .68 to 1 dollar which will just add one more dollar to 3,566
[tex]3,566.32[/tex] ⇒ [tex]3,567.00[/tex] (since .32 is below .50, you can't round it UP)
Add you $ symbol
With the result being: $3,567.00
