Part a) Use a system of inequalities to model the scenario
Let
x-------> represent babysitting hours
y-------> represent tutoring hours
we know that
--------> inequality
--------> inequality
Part b) Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week
we know that
--------> inequality
This inequality represent Jeanne’s possible number of hours worked this week
Using a graph tool
the solution of this inequality is the shaded area
see the attached figure N
--------> inequality
This inequality represent Jeanne’s probable income earned this week
Using a graph tool
the solution of this inequality is the shaded area
see the attached figure N
Part c) Analyze the set of coordinate values that represent solutions for the model created in part A. Choose one of the coordinates within the solution and algebraically prove that the coordinate represents a true solution for the model
we have the system of inequalities
--------> inequality
--------> inequality
the solution of the system of inequalities is the shaded area
using a graph tool
see the attached figure N
Let
------> see the attached figure N
The point belongs to the shaded area, so it is a system solution.
If the point is a solution, it must satisfy both inequalities.
Prove algebraically
substitute the value of x and y in the inequalities
inequality
------> is ok
inequality
-------> is ok
the point A satisfy both inequalities
therefore
the point A is a solution of the system
Answer:
the answer is B, Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week.

The cost of 5 cans of pinto beans is $3.35.
elps
At this rate, how much do 11 cans of pinto beans cost?
Answer:
About $16.42
Step-by-step explanation:
Since you know the overall price of 5 cans of pinto beans is 3.35, you divide 5 by 3.35, to get the price of one can.
5 / 3.35 = 1.49, giving you the price of one can of pinto beans
You then multiply this number by 11, which gives you 16.42 (rounded)

Two positive improper fractions are multiplied. Is the product sometimes, always, or never less than 1? Explain.
Answer:
The answer is yes, when two improper fractions is multiplied, the product will always be more than one.
Because when you convert an Improper fraction, the decimal value of it is always more than 1. Thus any improper fraction, added or multiplied with each other the answer will always be more than 1.
Example:
5/ 2 = this is an improper fraction. To convert it into decimal divide the denominator from the numerator
=> 5 / 2
=> 2 1/2

Answer:
27/50
Step-by-step explanation:
Answer:
27/50
Step-by-step explanation:
54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.

The cost of a car rental is $40 plus $0.18 per mile. You are on a budget of $67. Write and solve an inequality to find the greatest distance you can drive while staying within your budget.
Answer:
You can pay a maximum of $84.
formula is:
84 = 40 + .22*m
subtract 40 from both sides of this equation to get:
44 = .22*m
divide both sides of this equation by .22 to get:
44/.22 = m
simplify to get:
m = 200
you can go at most 2

An algebraic expression is described as 4 less than the product of 16
and the sum of hand 5. What is the value of this expression when
h = 92
Please help me
Answer:
Below in bold.
Step-by-step explanation:
The expression is:-
f(h) = 16(h + 5) - 4
When h = 92:
f(92) = 16(92 + 5) - 4
= 16 * 97 - 4
= 1552 - 4
= 1548.

Answer:
D. 1356.5 cm³
Step-by-step explanation:
The volume of a cone can be represented by:
V = (π)(r²)(h/3)
Substitute the known values:
π = 3.14
r = 12
h = 9
V = (3.14)(12²)(9/3)
Square 12.
V = (3.14)(144)(9/3)
Divide 9 by 3.
V = (3.14)(144)(3)
Multiply 3.14 and 144.
V = (452.16)(3)
Multiply 452.16 and 3.
V = 1356.48
Round to the nearest tenth.
V = 1356.5.

Graph the line with slope 2 passing through the point (-1, -3).
Answer:
Step-by-step explanation:
Start with the standard equation of a straight line, y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We know m, so:
y = 2x + b
Now find b by using the given point (-1,-3)
y = 2x + b
-3 = 2(-1) + b
b = -1
The equation is y=2x-1

(i) Here in ∆ AED and ∆ CEB ,
ang . DAE = ang. BCE AD = BC ang. AED = ang. BECHence by AAS congruence congruence condition ,
∆AED [tex]\cong [/tex] ∆CEBAlso ,
AE = CE . . . . . (i) BE = DE . . . . . (ii)==========================================
(ii) In ∆ AEB and ∆CED ,
AE = CE BE = DE ang. DEC = ang. AEB ( vertically opposite angles)Hence by SAS condition ,
∆AEB [tex]\cong [/tex] ∆CED===========================================

Hence Proved !Satchmo bought half pound of mangoes for $6 how much would he pay for 13/4 pounds of mangoes ?
Answer: 39
Step-by-step explanation: 1/2 = 6
13/4 = x
cross mutiply13/4 * 6=19.5divide both sides by 1/2answer is 39If Satchmo bought half pound of mangoes for $6 then he pay $39 for 13/4 pounds of mangoes.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that Satchmo bought half pound of mangoes for $6
We need to find the amount he has to pay for 13/4 pounds of mangoes.
Let x be the amount he has to pay for 13/4 pounds of mangoes..
We find the value of x by forming a proportional equation by given data.
1/2/6=13/4/x
1/12=13/4x
Apply cross multiplication
4x/12=13
x/3=13
x=39
Hence, Satchmo pay $39 for 13/4 pounds of mangoes.
