Answer:
The parents sell 48 pretzels.
Step-by-step explanation:
Let a be the number of bags of popcorn sold, and b the number of pretzels sold.
2.5a + 2b = 336
a = 2b
2.5a + a = 336
3.5a = 336
a = 96
b = 48

Step-by-step explanation:
Your literature class will read 4 novels this year, chosen by class vote from a list of 7 possible books offered by the teacher.
a) How many different ways could the course unfold, given that it probably matters what order you read the books in?
b) How many different choices of books could the class make?
a) The number of different ways the course could unfold is
Answer:
a) 840 different ways
b) 35 different choices of books
Step-by-step explanation:
We know that our literature class will read a total of 4 novels this year.
All novels chosen by class vote from a list of 7 possible books offered by the teacher.
Wherever we have an experiment [tex]''N''[/tex] which is formed by sub - experiments that can occurred in [tex]m_{1},m_{2},...,m_{n}[/tex] ways, the total number of ways in which the whole experiment [tex]''N''[/tex] can be developed is :
[tex]m_{1}[/tex] x [tex]m_{2}[/tex] x ... x [tex]m_{n}[/tex]
Then, for a) if it matters what order we read the books in, the total number of different ways could the course unfold is :
[tex](7).(6).(5).(4)=840[/tex] (I)
Because for the first book there are 7 different choices. Now, given that we choose the first book, we only have 6 different choices for the second one.
Continuing with the idea, we deduce the equation (I).
For item b) :
Wherever we have [tex]''n''[/tex] different objects and we want to find the ways that we can choose [tex]''r''[/tex] objects from that group, we need to use the combinatorial number.
We define the combinatorial number as :
[tex]nCr=\left(\begin{array}{c}n&r\end{array}\right)=\frac{n!}{r!(n-r)!}[/tex]
Then, if we apply this to the problem, the total different choices of books if we want 4 novels voting from a total of 7 possible books is :
[tex]7C4=\frac{7!}{4!(7-4)!}=35[/tex]
a) 840 different ways
b) 35 different choices of books
Juan rented a chainsaw from Steve's Tools. It cost $19 plus $6 per hour. If Juan paid
$49, then he rented the chainsaw for how many hours?
Answer:
2 hours
Step-by-step explanation:
if you do 19x2 then that is 38 and then you have to add 6 dollars per hour so that would be 2 hours
Eric and Shiloh each have a savings account. The ratio of Eric's balance to Shiloh is 4:3. Together they have a total of $40 in their accounts. How much money does each bar represent
Answer:
[tex]Eric= \$22.86[/tex]
[tex]Shiloh = \$17.14[/tex]
Step-by-step explanation:
Represent Eric with E and Shiloh with S;
[tex]E:S = 4:3[/tex]
[tex]Total = \$40[/tex]
Required
Determine the how much money each have
We have to convert the ratio to fraction;
For Eric, we have
[tex]Eric= \frac{E}{E + S} * Total[/tex]
[tex]Eric= \frac{4}{4 + 3} * \$40[/tex]
[tex]Eric= \frac{4}{7} * \$40[/tex]
[tex]Eric= \frac{\$160}{7}[/tex]
[tex]Eric= \$22.86[/tex]
[tex]Shiloh = Total - Eric[/tex]
[tex]Shiloh = \$40 - \$22.86[/tex]
[tex]Shiloh = \$17.14[/tex]

Answer:
m = 3/2
General Formulas and Concepts:
Pre-Alg
Equality PropertiesAlg I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define function
3x - 2y = 5
Step 2: Rewrite
Subtract 3x on both sides: -2y = 5 - 3xDivide -2 on both sides: y = -5/2 + 3/2xRewrite: y = 3/2x - 5/2Step 3: Identify
Slope m = 3/2

Step-by-step explanation:
A hospital bill is estimated to be $480.00. It ends up actually costing the patient $524.50. What is the percent of error in the bill? Round to the nearest tenths place.
Answer: 8.484%
Step-by-step explanation:
The formula for percentage error is calculated as:
= (actual value observed - expected value) / expected value × 100
where,
Actual value observed = $480.00
Expected value = $524.50
Percent error = ($480.00 - $524.50)/$524.50 × 100
= -$44.50/$524.50 × 100
= -0.08484 × 100
= -8.484
= 8.484%

Answer:
x>-1
Step-by-step explanation:
first, you have to distribute. 12x+8-6>2x-16+8
then you have to combine like terms 12x+2>2x-8
you put the X's on one side 10x+2> -8
move the 2 to the -8 10x>-10
divide x>-1
Answer:
Number 2. x>-1
Step-by-step explanation:
4(3x+2) is 12x+8. 12x+8-6 is 12x+2.
12x+2>8+2(x-8)
2(x-8) is 2x-16. 2x-16+8 is 2x-8.
12x+2>2x-8
12x>2x-10
10x>-10
x>-1
what is the percent of change between 57000 people and 97000 people, and how do I solve it?
Answer:
58.76
Step-by-step explanation:
So, as you can tell 97,000 is the 100 percent of the people, in this case we don't know what 57,000 is. Just divide equation 1 by equation 2. Considering both have the same unit. I'm so sorry, if this doesn't explain the best way.

The order pairs (1, 2), (2, 5), (3, 10), (4, 17), and (5, 26) represent a function. What is a rule that could represent this function?
A. y = x2 + 1
B. y = x2 − 1
C. y = x2
D. y = x + 1
Answer:
The answer is A
Step-by-step explanation:
1 to the second power is 1 + 1 = 2
2 to the second power is 4 + 1 = 5
3 to the second power is 9 + 1 = 10
4 to the second power is 16 + 1 = 17
5 to the second power is 25 + 1 = 26
y = x² + 1 is a rule that could represent the given function.
Given that,
The order pairs (1, 2), (2, 5), (3, 10), (4, 17), and (5, 26) represent a function, what is a rule that could represent this function is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
While observing the pattern of pair it is found that every ordinate is 1 more the square of its abscissa, so the general equation for the function is given as,
y = x² + 1
Thus, y = x² + 1 is a rule that could represent the given function.

Step-by-step explanation:
In right triangle XYZ, the tangent of acute angle X is 4. What is the secant of angle X?
Answer:
The secant of angle x; sec x = √17
Step-by-step explanation:
Here, given the tangent of an angle, we want to find the value of the secant
Mathematically;
sec^2 x = 1 + tan^2 x
This is from trigonometric identity
Thus;
sec x = √(1 + tan^2 x)
According to the question;
tan x = 4
So tan^2 x = 4^2 = 16
Thus;
sec x = √1 + 4^2
sec x = √17

Answer:
$6.00
Explanation:
10% of 200 is 20
20/30 = $.6666
Each parent gets $0.67 off.
$200/30 = $6.6666
$6.6666 ---> $6.67
6.67 - 0.67
= 6.00
Check:
6.00 * 30 = 180
200-180 = 20

Answer:
Each parent pays an amount of £6.
Step-by-step explanation:
Cost of the hall = £200
Discount for parents = 10%
Cost of the hall for parents
= 200 - 10% of 200
= 200 - 10/100 × 200
= 200 - 10 × 2
= 200 - 20
= £180
If 30 parents share the cost equally,
Each parent has to pay

Line p passes through point (0, 8) and is perpendicular to the graph of y = 1/4 x + 2. Line q is parallel to line p and passes through point (-3, 6). Which is the equation of line q in slope-intercept form? A. y= 1/4x+6 B. y = -1/4 x + 8 C. y = 4x – 8 D. y=-4x - 6
Answer:
A
Step-by-step explanation:
Because when the line passes through (0,8) with perpendicular to the graph of y =1/4 x =2 it equals y+1/4x+6.
The equation of line q in slope-intercept form is y = -4x - 6 if the line p passes through the point (0, 8) and is perpendicular to the graph of y = 1/4 x + 2.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
Line p passes through the point (0, 8) and is perpendicular to the graph of y = 1/4 x + 2.
The slope of the line p is:
m(p) = -4
The slope of the line q parallel to line p:
m(q) = -4
The equation of the line q:
y - 6 = -4[x + 3]
Line q passes through the point (-3, 6).
The equation of the line:
y = -4x - 12 + 6
y = -4x - 6
Thus, the equation of line q in slope-intercept form is y = -4x - 6 if the line p passes through the point (0, 8) and is perpendicular to the graph of y = 1/4 x + 2.

Find the amplitude, the EoA=y, the period, and the phase shift in terms of cosine for this graph.
Answer:
Step-by-step explanation:
or
Step-by-step explanation:
has:
1) amplitude=|a|
2) phase shift=b
3) period=2pi/c
d) vertical shift=d
--------------------------------------------------
You are given the amplitude is 2. This means a could either be 2 or -2.
You are given phase shift is -1/8. This means b is -1/8.
You are given the period is pi. So we need to solve pi=2pi/c.
pi=2pi/c
Dividing both sides by pi gives:
1=2/c
Multiply both sides by c gives:
c=2
The vertical shift is -2 so d=-2.
The equation could either be:
y=2cos(2(x-(-1/8)))-2
or
y=-2cos(2(x-(-1/8)))-2
Simplifying a little gives:
y=2cos(2x+1/4)-2
y=-2cos(2x+1/4)-2
