The price of a cup of coffee has risen to $2.45 today. Yesterday's price was $2.15. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answer:
14%
Step-by-step explanation:
To find the percentage change of any two amounts you just need this formula: (new - old) ÷ old
New price = $2.45
Old price = $2.15
2.45 = 2.15 = 0.3
0.3 ÷ 2.15 = 0.139534883721
This would make the percentage increase = %13.9534883721
But the question wants it rounded to the near tenth, so it's %14
Answer:
13.9535% increase, so yeah, like, 14%

Find an equation for the line parallel to 3x+5y-4=0, with the same x-intercept as 2x-3y-6=0.
Answer:
It is 4y = -3x + 9
Step-by-step explanation:
[tex]3x + 5y - 4 = 0 \\ 5y = - 3x + 4 \\ y = - \frac{3}{4} x + 4[/tex]
since it is parallel, its slope, m is -¾
[tex]2x - 3y - 6 = 0 \\ - 3y = - 2x + 6 \\ y = \frac{2}{3} x - 2[/tex]
at x-intercept, y is zero
[tex]2 = \frac{2}{3} x \\ x = 3[/tex]
therefore
[tex]y = mx + c \\ 0 = ( - \frac{3}{4} \times 3) + c \\ c = \frac{9}{4} [/tex]
equation is
[tex]y = - \frac{3}{4} x + \frac{9}{4} \\ \\ 4y = - 3x + 9[/tex]

Apositive integer n is called special if n is divisible by 4. n +1 is divisible by 5, and n + 2 is divisible by 6. How many special integers smaller than 1000 are there,
Answer: 17
Hello,
Step-by-step explanation:
n is divisible by 4.
n +1 is divisible by 5
n + 2 is divisible by 6
n <1000
[tex]\left\{\begin{array}{ccc}n&=&4*k_1\\n+1&=&5*k_2\\n+2&=&6*k_3\\\end{array}\right.\\\\4*k_1+1=5k_2\Longrightarrow\ k_2=\dfrac{4k_1+1}{5} \Longrightarrow\ k_1=1+5*t\ , k_2=1+4*t\\\\4*k_1+2=6k_3\Longrightarrow\ k_3=\dfrac{4(1+5t)+2}{6} \Longrightarrow\ k_3=1+\dfrac{10*t}{3} \\\\\Longrightarrow\ t=3z\\k_3=1+10z\\n+2=6(1+10z)\\n=4+60z\\\\1000 < 4+60z \Longrightarrow\ z \leq 16\\[/tex]
There are 17: from 4+0*60=4 to 4+16*60=964.
Answer:
17
Step-by-step explanation:
these positive integers are :
4, 64, 124, 184 ... , 964
964 = 4 + (n-1) (60)
964 = 4 + 60n -60
964 = 60n -56
60n = 1020
n = 1020/60
n = 17
so, the number of special integers smaller than 1000 are = 17

Answer:
D. It is a function, but it is not one-to-one.
Step-by-step explanation:
A function means that each x value has only 1 y value assigned to it.
It is not one-to-one because the x value 0 does not have any y value assigned to it. This is called an asymptote.

Answers:
2^3 = 83^2 = 93^3 = 274^3 = 645^2 = 258^2 = 64==============================================
Explanation:
The notation 5^2 is the same as writing [tex]5^2[/tex]
The second number is the exponent and it tells us how many copies of the base to multiply together. In the example 5^2, we have two copies of 5 multiplied to get 5^2 = 5*5 = 25
As another example, 4^3 = 4*4*4 = 64. We have three copies of 4 multiplied due to the exponent 3. You can use a calculator for this, but I recommend doing this by hand to get practice.
Note how 4^3 = 64 and 8^2 = 64. So 64 is used twice (which is why we have two tiles labeled "64").
The tiles labeled 9, 12, 10, and 16 are never used since they don't have any matching exponential expression.
4 A curve has equation y=x^3 - 2x² +5. Find the coordinates of its two stationary points.
Answer:
Stationary points are (0, 5) and (4/3, 103/27)
Step-by-step explanation:
At stationary point (turning point), dy/dx :
[tex]y = {x}^{3} - 2 {x}^{2} + 5 \\ \frac{dy}{dx} = 3 {x}^{2} - 4x \\ \\ \frac{dy}{dx} = x(3x - 4)[/tex]
but dy/dx = 0:
[tex]x(3x - 4) = 0 \\ either \: x \: is \: 0 \: and \: (3x - 4) = 0 \\ x = 0 \\ and \\ 3x - 4 = 0 \\ x = \frac{4}{3} [/tex]
let y = x³ - 2x² + 5:
[tex]when \: x \: is \: 0 \\ y = 5 \\ when \: x \: is \: \frac{4}{3} \\ \\ y = {( \frac{4}{3}) }^{3} - 2 {( \frac{4}{3} )}^{2} + 5 \\ \\ y = \frac{103}{27} [/tex]

Answer:
\begin{gathered} = (4x + 8)(2x - 12) \\ = ( {8x}^{2} - 48x + 16x - 96) \\ = (8 {x}^{2} - 32x - 96) \\ = 8( {x}^{2} - 4x + 12)\end{gathered}

if angle 4 is 52.7, what are the measures of angles 1,2, and 3?
Answer:
127.352.7127.352.7Step-by-step explanation:
Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).
52.7 + x = 180
x = 127.3

A farmer is making a circular pen for her pigs. She needs the pen to have a diameter of 26 feet. If fencing costs $32 per foot, which is the closest to the total cost of the fence that the farmer needs to make the pen?
A) $2894.01
B) $ 2765.19
$ 2612.48
D) $ 2578.94
Answer:
C
Step-by-step explanation:
circumference= 2* pie*(26/2)
Answer:
[tex]\boxed {\boxed {\sf C. \$ 2612.48 }}[/tex]
Step-by-step explanation:
We are asked to find the cost of the fence a farmer needs to make a pen.
FeetThe fence is used to make a circle. We want to find the cost, but we first need to find how many feet of fence is needed. Essentially, we have to find the perimeter, but this is called the circumference because it is a circle. The formula for calculating circumference is:
[tex]c= \pi d[/tex]
The diameter (d) of the pen is 26 feet and we can use 3.14 for pi. Substitute these values into the formula.
[tex]c=3.14 * 26 \ ft[/tex]
Multiply.
[tex]c= 81.64 \ ft[/tex]
CostThe farmer needs 81.64 feet of fencing. The cost of fencing is $32 per foot, so we multiply the cost by the feet needed.
[tex]\$32 / ft * 81.64 \ ft[/tex]
The units of feet cancel
[tex]\$ 32 * 81.64[/tex]
[tex]\$2612.48[/tex]
The cost of the fencing is $2612.48 and choice C is correct.
