Step-by-step explanation:
A 20% apple juice drink is mixed with a 100% apple juice drink. The function f(x)=(2)(1.0)+x(0.2)2+x models the concentration of apple juice in the drink after x gallons of the 20% drink are added to 2 gallons of pure juice. What will be the concentration of apple juice in the drink if 6 gallons of 20% drink are added? Give the answer as a percent but do not include the percent sign (%).
Answer: 40
Step-by-step explanation:
The concentration of pineapple when 2 gallons of pineapple juice are added to 6 gallons of the other juice is; 8.24
What are Functions?The function is a type of relation, or rule, that maps one input to a specific single output.
Given that the functions that model the concentration of apple juice in the drink after x gallons of the 20% drink are added to 2 gallons of pure juice.
f(x)=(2)(1.0)+x(0.2)²+x
If the concentration of apple when 2 gallons of apple juice are added to 6 gallons of the other juice;
f(6) = (2)(1.0)+ 6(0.2)²+ 6
f(6) = 2.0 + 6.24
f(6) = 8.24
Hence the concentration of pineapple when 2 gallons of pineapple juice are added to 6 gallons of the other juice is; 8.24

there is a loss of 20% by selling a photocopy machine for rs 60000 at what price will the machine be sold to gain 12% find it
Answer:
Step-by-step explanation:
Loss is 20%
S.P=Rs60000
C.P=S.P*100/100-loss%
=60000*100/80=Rs75000
So he brought is at Rs75000
Now he wants 12% profit
So
S.P=(100+profit%)/100*C.P
=100+12/100*75000
=112/100*75000=Rs 84000
He will have to sell Rs14000 more to gain profit of 12%
Kevin claims that the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself is 156° since 180(15−2)15=156. Decide if Kevin is correct. If Kevin is correct, enter 156 below. If Kevin is incorrect, enter the correct value of the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself.
Answer:
Step-by-step explanation:
The formula for calculating the interior angle of a polygon is expressed as;
sum of internal angle = (n-2)180 where;
n is the number of sides of the polygon in consideration.
Given a 15 sided polygon, n = 15
sum of internal angle = (15-2)180
sum of internal angle = (13)180
sum of internal angle = 2340
Hence kevin is wrong, the correct answer is 2340

What is the area of this composite figure
189.25 in2
228.5 in2
150 in2
78.5 in2
Answer:
189.25 in²
Step-by-step explanation:
First, let us find the area of the rectangle.
Area = Length × Width
= 15 in × 10 in
= 150 in²
Then let us find the area of the semicircle.
Area = [tex]\frac{1}{2}[/tex] × π r²
= [tex]\frac{1}{2}[/tex] × 3.14 × 5 × 5
= 0.5 × 3.14 × 25
= 1.57 × 25
= 39.25 in²
Now let us find the total area of the composite figure.
Total area = Area of the rectangle + Area of the semi-circle.
= 150 in² + 39.25 in²
= 189.25 in²

Jan says that 2 is between 0 and 3/4 on a number line. Do you agree? Why or why not?
Answer:
No
Step-by-step explanation:
2 is a positive whole number with a value greater than 1. 3/4 is NOT greater than 1. So 2 is greater than both 0 AND 3/4 and cannot be between the two numbers.
No, Jan is wrong because 2 is not in between 0 and 3/4 on a number line.
What is Number line?
Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Jan says that 2 is between 0 and 3/4 on a number line.
Here, The numbers on the number line are 0 and 3/4.
⇒ 3 / 4 = 0.75
So, We get;
⇒ 2 > 0
And, 3/4 < 2
Thus, The number 2 is not in between 0 and 3/4 on a number line.

Does the system of equations below have no solution, 1 solution, or infinite solutions
= 2 − 1
= 2 + 4
Answer:
no solution
Step-by-step explanation:
y = 2x - 1 → (1)
y = 2x + 4 → (2)
substitute y = 2x - 1 into (2)
2x - 1 = 2x + 4 ( add 1 to both sides )
2x = 2x + 5 ( subtract 2x from both sides )
0 = 5 ← not possible
This indicates the system has no solution

Answer:
He will drive 180 miles in 4 hours. ( I think)
Step-by-step explanation:
If he keeps going at his rate which is 45 mph then if you multiply that by 4 then your answer should just be 180 miles.
Answer:
180 miles
Step-by-step explanation:
so he goes 45 miles per hour
since you need to find 4 hours just multiply 45 by 4
45 x 4 = 180

The table shows the average cost of gasoline in the United States in dollars per gallon for the given years.
Year 1995 1996 2000 2001 2005 2006 2010 2011 2013 2014
Price per gallon ($) 1.13 1.14 1.33 1.49 1.88 2.36 2.77 3.15 3.39 3.40
(a) Write the least squares regression equation that models the data. Let x = time in years since 1995 and let y = price per gallon.
(b) Use the equation to estimate the price per gallon in 2030. Show your work.
From the given table, the year values, and prices, we have the following
equation and values;
(a) The least squares regression equation is; y ≈ 0.1316·x - 261.73
(b) The estimate of the price per gallon in 2030 is approximately $5.418
How can the equation and price be obtained from the table?(a) The coefficients of the least squares regression formula are
presented as follows;
[tex]a = \mathbf{\overline y - b \cdot \overline x}[/tex]
[tex]b = \mathbf{\dfrac{\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) }{\sum \left(x_i - \bar x\right )^2 }}[/tex]
Entering the given values in MS Excel, we have;
[tex]\overline x[/tex] = 2005.1
[tex]\overline y[/tex] = 2.204
[tex]b = \dfrac{56.456 }{428.9} \approx 0.1316[/tex]
a = 2.204 - 0.1316 × 2005.1 ≈ -261.73
The least squares regression equation is therefore;
[tex]\underline{y =0.1316\cdot x - 261.73}[/tex](b) In the year 2030, we have;
The price, y ≈ 0.1316 × 2030 - 261.73 = 5.418
In the year 2030, the price per gallon will be approximately $5.418

Find the slope between the two points given. Then, use the slope and the first point to write the equation of the line in Point-Slope form. State the slope. Point One: (−4,5) Point Two: (0,0)
The slope is -5/4 and the equation of the line in point-slope form is y-5 = -5/4(x+4) + c.
What is slope of a line?The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.
For the given situation,
The points are (x1,y1) is (−4,5) and (x2,y2) is (0,0)
The formula of slope is
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
⇒ [tex]m=\frac{0-5}{0-(-4)}[/tex]
⇒ [tex]m=\frac{-5}{4}[/tex]
The equation of the line in point-slope form is
[tex]y-y1=m(x-x1)[/tex]
⇒ [tex]y-5=\frac{-5}{4} (x-(-4))[/tex]
⇒ [tex]y-5=\frac{-5}{4} (x+4)[/tex]
Hence we can conclude that the slope is -5/4 and the equation of the line in point-slope form is y-5 = -5/4 (x+4).

What is the perimeter of a square if its area is 50 cm??
Answer:
28.4 (rounded)
Step-by-step explanation:
7.1 times 7.1 is 50. To calculate area, you need to multiply 2 of the sides. so, that is the side length.
then, you multiply it by 4 for all four sides. that would be 28.4.
Answer:
54 or 30
Step-by-step explanation:
Perimeter is adding all the sides together. Area is multiplying LxW and 50 can be gotten by multiplying 5 by 10, or 25 by 2. So if you went by 5x10, both lengths would be 5 and the widths would be 10 or vice versa. Same goes for if you multiplied 25 by 2.
