Answer:
The groomer can get 40 bottles out of the 5 gallon pail.
Step-by-step explanation:
A gallon contains 128oz (ounces)
128/16=8
8 bottles/gallon
times both sides by 5
40 bottles/5 gallons

Standard Form: ax² + bx + c = 0Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]Algebra II
Imaginary roots: √-1 = iStep-by-step explanation:
Step 1: Define function
f(x) = -x² - 6x - 14
Step 2: Set up
Set equation equal to 0: -x² - 6x - 14 = 0Factor out -1: -(x² + 6x + 14) = 0Divide both sides by -1: x² + 6x + 14 = 0Step 3: Define variables
a = 1
b = 6

Answer:
The two digit number is 35.
Step-by-step explanation:
Let xy be the two digit number
According to given statement
[tex]x+y = 8\ \ \ \ Eqn\ 1[/tex]
The place value of xy is 10x+y
Reversing the number will be: 10y+x
It is also mentioned that the new number is previous number increase by 18
So,
[tex]10y+x = 10x+y+18\\10y-y+x-10x = 18\\9y-9x = 18\\9(y-x) = 18\\\frac{9(y-x)}{9} = \frac{18}{9}\\y-x = 2\ \ \ Eqn\ 2[/tex]
From equation 2
[tex]y = 2+x[/tex]
Putting in equation 1
[tex]x+y = 8\\x+2+x = 8\\2x+2 = 8\\2x = 8-2\\2x = 6\\\frac{2x}{2} = \frac{6}{2}\\x = 3[/tex]
Putting x = 3 in equation 1
[tex]3+y = 8\\y = 8-3 = 5[/tex]
xy = 35
Hence,
The two digit number is 35.

Answer:
x = 35
Step-by-step explanation:
The segment from the vertex of the triangle is an angle bisector and divides the opposite side into 2 segments that are proportional to the other 2 sides, that is
[tex]\frac{20}{x}[/tex] = [tex]\frac{8}{14}[/tex] ( cross- multiply )
8x = 280 ( divide both sides by 8 )
x = 35

A bakery mixes cookie dough in large batches. For chocolate chip cookies,10 cups of sugar and 20 cups of flour are needed. Write the ratio of sugar to flour for chocolate chip cookies. Express your answer as a simplified ratio.
Answer:
1 cup of sugar for every 2 cups of flour 1:2
Step-by-step explanation:
The ratio of sugar to flour for chocolate chip cookies, to maintain the same taste, will be 1/2.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
A bakery mixes cookie dough in large batches.
For chocolate chip cookies, 10 cups (2,365.88 ml) of sugar and 20 cups (4,731.76 ml) of flour are needed.
Then the ratio of sugar to flour for chocolate chip cookies to maintain the same taste, will be
Let S be the amount of sugar and F be the amount of the flour.
Then the ratio of sugar to flour will be
S / F = 10 / 20
S / F = 1 / 2
Thus, the ratio of sugar to flour for chocolate chip cookies, to maintain the same taste, will be 1/2.

Answer:
y = 4x + 14
Step-by-step explanation:
slope-intercept form: y = mx + b
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.
To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:
[tex]\frac{18-14}{1-0}[/tex]
Simplify:
18 - 14 = 4
1 - 0 = 1
[tex]\frac{4}{1}=4[/tex]
The slope is 4.
To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:
y = mx + b
18 = 4(1) + b
18 = 4 + b
14 = b
The y-intercept is 14.
Now that we know the slope and the y-intercept, we can write the equation:
y = 4x + 14

Answer:

Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 4, 3 ] , then
f(b) = f(3) = 3² - 3 - 8 = 9 - 3 - 8 = - 2
f(a) = f(- 4) = (- 4)² - (- 4) - 8 = 16 + 4 - 8 = 12 , tus
average rate of change = [tex]\frac{-2-12}{3-(-4)}[/tex] = [tex]\frac{-14}{7}[/tex] = - 2

A set of 4 consecutive odd integers has a sum of 216. What are the integers?
Answer:
Hope this helps!!
Step-by-step explanation:
So the four consecutive odd integers are: 51 , 53 , 55 and 57 .
If the first integer is n, then the other three are n+2,n+4 and n+6
and we have:
216=n+(n+2)+(n+4)+(n+6)=4n+12
Subtract 12 from both ends and transpose to get:
4n=204
Divide both sides by 4
to get:
n=51
So the four consecutive odd integers are:
51,53, 55 and 57.

Question 2 An exponential model y = a.6 passes through the points (0,9) and (3,243). What are the values of a and b?
Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a [tex]b^{x}[/tex]
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 )
a = 9
y = 9 [tex]b^{x}[/tex]
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b = [tex]\sqrt[3]{27}[/tex] = 3
y = 9[tex](3)^{x}[/tex] ← exponential equation
