18 is 14 percent of what?
Answer:
18 is 14% of 128.5714
Step-by-step explanation:
it's 77.78
Step-by-step explanation:
14: 18*100 =
(14*100): 18 =
1400: 18 = 77.78
Now we have: 14 is what percent of 18 = 77.78
Question: 14 is what percent of 18?
Percentage solution with steps:
Step 1: We make the assumption that 18 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=18$100%=18.
Step 4: In the same vein, $x\%=14$x%=14.
Step 5: This gives us a pair of simple equations:
$100\%=18(1)$100%=18(1).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{18}{14}$100%x%=1814
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{14}{18}$x%100%=1418
$\Rightarrow x=77.78\%$⇒x=77.78%
Therefore, $14$14 is $77.78\%$77.78% of $18$18.

1/2x - 7 = 1/3 (x- 12)
Answer:
x = 18
Step-by-step explanation:
1/2x - 7 = 1/3 (x- 12)
Multiply both sides by 3
3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)
3/2x - 21 = x - 12
Collect like terms
3/2x - x = 21 - 12
1/2x = 9
Multiply both sides by 2
x = 2 * 9
x = 18
Answer:
x = 18

5. A robot that picks up tennis balls is on a straight path from (8,6) toward a ball at (-10,-5). The robot picks up a ball at (-10,-5) and then turns 90° right. What are the coordinates of appoint that the robot can move toward to pick up the last ball?
Answer:
Step-by-step explanation:
so this question is about perpendicular lines. keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to . :) okay so what is that line the robot is on, let's first
find the slope , m
m = (y2 - y1) / ( x2 - x1)
P1 = (8,6) in the form ( x1,y1)
P2= (-10,-5) in the form (x2,y2)
then
m = (-5-6) / (-10-8)
m = -11 / -18
m = 11/ 18
and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick P1
y-6 = 11/18(x-8)
y = 11/18x - 88/18 + 6
y = 11/18x -88/18 + 108/18
y = 11/18x + 20/18
now let's take the reciprocal of the slope and change the sign, then we have
y = - 18/11x +20/18 ( coordinates robot can move on )
on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

A loan of$8000 was repaid in 24 equal monthly installments of $400 . The rate of interest on the loan was
Answer:
1%
Step-by-step explanation:
24(400) = 9600 = total amt paid
9600 - 8000 = 1600 = amt of interest paid
I = PRT T = 2 yr
1600 = 8000(2)R
1600 = 16000R
1600/16000 = 1/10 = .01 = 1%
The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.
Answer:
Radius - 4
Apothem - 2
Area - [tex]12\sqrt{3}[/tex] or 20.8
Step-by-step explanation:
Try to draw out my explanation so you know what this looks like.
~~~~
This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...
[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]
Now that we know the side lengths, we can get this started!
~~~~
Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.
4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.
[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]
By the way, the formula for the area can be either of the two:
[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]
we can easily find the area using the first formula.
[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]
The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...
So we can divide the big triangle into a mini triangle at the bottom left/right
The height (small leg) of that triangle would be the apothem
The hypotenuse of that triangle would be the radius.
I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

A vet borrows $12,000 for 4 years. The total interest paid was $960. What was the interest rate on the loan?
Answer:
2% per year.
Step-by-step explanation:
Solving our equation
r = 960 / ( 12000 × 4 ) = 0.02
r = 0.02
converting r decimal to a percentage
R = 0.02 * 100 = 2%/year
The interest rate required to
accumulate simple interest of $ 960.00
from a principal of $ 12,000.00
over 4 years is 2% per year.

Negative 0.2 (x minus 4) = negative 1.7
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 4 = negative 1.7.
Negative 0.2 x = 2.3. x = negative 11.5.
Negative 0.2 (x minus 4) = negative 1.7.
x minus 4 = 0.34. x = 4.34.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.
Negative 0.2 x = negative 2.5. x = 12.5.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 0.8 = negative 1.7.
Negative 0.2 x = negative 0.9. x = 4.5.
Answer:
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.

What are the coordinates of the focus of the parabola? (x+1)2=−8(y−2) (−1, 2) (1, −2) (−1, 0) (−1, 1)
Answer:
[tex](x,y) = (-1,0)[/tex]
Step-by-step explanation:
Given
[tex](x+1)^2 = -8(y-2)[/tex]
Required
The coordinates of the focus
First, write the expression in form of: [tex]y=a(x-h)^2+k[/tex]
[tex](x+1)^2 = -8(y-2)[/tex]
[tex](x+1)^2 = -8y + 16[/tex]
[tex]-8y + 16 = (x+1)^2[/tex]
Subtract 16 from both sides
[tex]-8y = (x+1)^2 - 16[/tex]
Divide through by -8
[tex]y = -\frac{1}{8}(x+1)^2 - \frac{16}{-8}[/tex]
[tex]y = -\frac{1}{8}(x+1)^2 +2[/tex]
In this case:
[tex]a = -\frac{1}{8}[/tex]
[tex]-h = 1[/tex] [tex]h = -1[/tex]
[tex]k = 2[/tex]
The focus of the parabola is:
[tex](x,y) = (h,k + \frac{1}{4a})[/tex]
This gives:
[tex](x,y) = (-1,2 + \frac{1}{4*-\frac{1}{8}})[/tex]
[tex](x,y) = (-1,2 + \frac{1}{-\frac{1}{2}})[/tex]
[tex](x,y) = (-1,2 -2)[/tex]
[tex](x,y) = (-1,0)[/tex]

A population of rabbits in a lab, p(x), can be modeled by the function p(x)=20(1.014)^x, where x represents the number of days since the population was first counted.
Answer:
(a) 20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b) Average Rate of change = 0.8
Step-by-step explanation:
P.S - The exact question is -
Given - A population of rabbits in a lab, p(x), can be modeled by
the function p(x)=20(1.014)^x, where x represents the number
of days since the population was first counted.
To find - (a) Explain what 20 and 1.014 represent in the context of
the problem.
(b) Determine, to the nearest tenth, the average rate of
change from day 50 to day 100.
Proof -
(a)
Given that the function p(x) is represented as
[tex]p(x) = 20(1.014)^{x}[/tex]
Here,
20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b)
Given,
[tex]p(x) = 20(1.014)^{x}[/tex]
When x = 50
[tex]p(50) = 20(1.014)^{50}[/tex] = 40.08000 ≈ 40.1
When x = 100
[tex]p(100) = 20(1.014)^{100}[/tex] = 80.32033 ≈ 80.3
Now,
Average Rate of change = [tex]\frac{p(100) - p(50)}{100 - 50}[/tex]
= [tex]\frac{80.3 - 40.1}{50}[/tex]
= [tex]\frac{40.2}{50}[/tex]
= 0.804 ≈ 0.8
⇒Average Rate of change = 0.8
Julio bought a fish tank shaped like a rectangular prism. The inside of the tank measures 24 inches in length, 10 inches in width, and 12 inches in height. The tank is filled with water to a height of 8 inches. How many more cubic inches of water are needed to fill the tank to the top? Use paper to show your work.
Answer:
[tex]Volume = 960in^3[/tex]
Step-by-step explanation:
Given
Empty Tank
[tex]Length = 24in; Width=10in; Height = 12in[/tex]
When filled with water, the height is:
[tex]Height = 8in[/tex]
Required
Determine how many more cubic inches needed
First, we calculate the difference between the height of the tank and the height of the water.
[tex]H = 12in - 8in[/tex]
[tex]H = 4in[/tex]
The volume of water to full the tank is then calculated as:
[tex]Volume = Length * Width * H[/tex]
[tex]Volume = 24in * 10in * 4in[/tex]
[tex]Volume = 960in^3[/tex]
