Jacob and Sarah are saving money to go on a trip. They need at least $1850 in order
to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $15
each time he mows a lawn and Sarah charges $10 each time she walks a dog. The
number of dog walks that Sarah has scheduled is no more than five times the
number of lawns Jacob has scheduled to mow. Sarah will walk at least 65 dogs.
Answers
Answer:
[tex]\textsf{Constraint 1}: \quad 15x+10y\geq 1850[/tex]
[tex]\textsf{Constraint 2}: \quad y \leq 5x[/tex]
[tex]\textsf{Constraint 3}: \quad y \geq 65[/tex]
Step-by-step explanation:
Inequality signs:
< Less than.≤ Less than or equal to.> More than.≥ More than or equal to.Given variables:
x = Number of lawns mowed.y = Number of dogs walked.Constraint 1Given information:
$15 = Charge for mowing a lawn.$10 = Charge for walking a dog.$1850 = Minimum amount needed for the trip.Therefore, the amount earned from mowing the lawns and walking dogs should be more than or equal to $1850:
[tex]\boxed{15x+10y\geq 1850}[/tex]
Constraint 2Given information:
The number of dog walks that Sarah has scheduled is no more than 5 times the number of lawns Jacob has scheduled to mow:Therefore, Sarah will walk less than or equal to 5 times the number of lawns mowed:
[tex]\boxed{y \leq 5x}[/tex]
Constraint 3Given information:
Sarah will walk at least 65 dogs.Therefore, Sarah will walk more than or equal to 65 dogs:
[tex]\boxed{y \geq 65}[/tex]

Step-by-step explanation:
Given:
ABCD is a parallelogram
So,
LINE AC || DC
Computation:
IN ΔAIE and ΔCIF
∠AIE = ∠CIF (Vertical opposite angle)
AI = IC (I is midpoint of line AC)
∠IAE = ∠ICF (Alternate angle)

A nurse assesses a 66 - year - old client who is attempting to quit smoking . The client states , " I started smoking at age 16 , and smoked one pack each day until 10 years ago . Then I decreased to a half of a pack per day . " How many pack - years should the nurse document for this client ?
Answers
The nurse should document for this client as 45 pack years.
Pack year is determined by dividing the quantity of packs smoked daily by the number of years the smoker has smoked.
total years of smoking = current age of the client - the year he started smoking
= 66 - 16
50 years of smoking
For 40 years he smoked 1 pack per day but then he reduced it to a half pf a pack per day
= 40 x 1 + 10 x 0.5
= 45 pack- years
The nurse should document for this client as 45 pack years as the client has started smoking at age 16 , and smoked one pack each day until 10 years ago then he had decreased to a half of a pack per day.

The rectangular garden is surrounded by a walkway.
The combined area of both is 7.5(6x+5) and the area of the garden alone is 6(3.5x+1.5).
The area of the walkway (Aw) around the garden is the result of subtracting the total area minus the inner area:

If x varies directly as y and z and inversely as the square
of r, and x = 16 when y = 3, z = 12 and r = 3, find
x when y = 5, z = 30, and r
r =10
Answers
Answer:
x = 6
Step-by-step explanation:
Take the statement x varies directly as y and z
This means value of x is directly proportional to the value of y and z represented as x ∝ yz which can be represented as x = k.y.z where k is a constant known as the constant of proportionality
If x varies inversely as the square of r we represent this as x ∝ 1/r² or in equation form x = k/r²
Since the value of x is dependent on the values of y, z and jointly we have a single equation of proportionality:
[tex]\bold{x= k\cdot\frac{yz}{r^{2}}}[/tex]
Given the values for x, y, z and r we can compute the proportionality constant and determine the value of x for any value of y, z or r
x = 16 when y = 3, z = 12 and r = 3
[tex]16 = k\cdot \frac{3\cdot 12}{3^2} \\\\16 = k\cdot \frac{3\cdot 12}{9}\\\\16 = k\cdot4\\\\k = 16/4 = 4\\[/tex]
So the constant of proportionality is k = 4. Us this value in the proportionality equation along with y, z and r to get the value of x
[tex]x = 4\cdot \frac{5\cdot 30}{10 \cdot 10}\\\\x = 4\cdot\frac{150}{100}\\\\x = \frac{600}{100} = 6\\\\[/tex]
So x = 6 is the answer
