The Humphrey family is traveling 1,325 miles for their family vacation. Last year, they traveled 724 miles. They drove 420 miles earlier in the week and have driven 130 miles so far today. How many miles do they have left to travel?
Answer: They have 775 miles left to be traveled
Step-by-step explanation:
Miles required to travel for vacation = 1,325 miles
Miles already traveled = Miles driven this week + miles driven today
= 420 miles + 130 miles
-=550 miles
Miles remaining to be covered =Miles required to travel for vacation --- Miles already traveled
= 1,325 miles - 550 miles
= 775 miles

Complete Question
The Hollywood cats are a group of cats that have settled in along the Hollywood Beach in Florida. A group of volunteers feed them and care for them while trying to humanely reduce their numbers (as they are considered a nuisance). If there were 100 cats in the year 2012 and the rate of population change is given
by [tex]-\frac{1}{4} t-2[/tex]
where t is measured in years, how many cats are projected to be in the group in 2020.
Answer:
The number of total cats left after 8 years T
[tex]T=76[/tex]
Step-by-step explanation:
From the question we are told that
Number of cats 2012 n=100
Number of years t=2012-2020=>8 years
Generally the equation of change in population is mathematically Given as
[tex]\frac{dp}{dt}= -\frac{1}{4} t-2[/tex]
[tex]\int dp=\int_0^8 (-\frac{1}{4} t-2)[/tex]
[tex]p=\frac{-64}{8} -16[/tex]
[tex]p=-24cats[/tex]
Therefore the number of total cats left after 8 years T is given as
[tex]T=100-24[/tex]
[tex]T=76[/tex]
A dish washer manufacturer introduced a new type of dish washer and conducted a survey on the new product. The survey showed 40% of the consumers had seen an advertisement for the new product, 20% had tried the new product, and 15% had both seen an advertisement and tried the new product. Let event A denote that the consumers had seen an ad for the new product, and event B denote that the consumers had tried the new product. What is the probability a randomly selected consumer had either seen an advertisement or tried the new product
Answer:
[tex]P(A \cup B) =0.45[/tex]
Step-by-step explanation:
From the question we are told that
Consumers seen the soap [tex]P_A=40\% =0.40[/tex]
Consumers used the soap [tex]P_B=20\% =0.2[/tex]
Consumers seen/tried the soap [tex]P_x=15\% =0.15[/tex]
Generally the probability that consumers have seen and tried the soap is
[tex]P(A \cup B=P(A)+P(B)-P(A \cap B[/tex]
[tex]P(A \cup B=0.4+0.2-0.15[/tex]
[tex]P(A \cup B) =0.45[/tex]

Working together, it takes two computers 12 minutes to send out a company's email. If it takes the slower computer 30 minutes to do the job on its own, how
long will it take the faster computer to do the job on its own?
Do not do any rounding?
Answer:
The faster computer will complete the job in 20 minutes alone.
Step-by-step explanation:
Given that:
Time taken by both computers = 12 minutes
Time taken by slower computer = 30 minutes
Let,
x be the time taken by faster computer.
[tex]\frac{1}{x}+\frac{1}{30} = \frac{1}{12}[/tex]
[tex]\frac{1}{x} = \frac{1}{12}-\frac{1}{30}\\\\\frac{1}{x} = \frac{5-2}{60}\\\\\frac{1}{x} = \frac{3}{60}\\\\\frac{1}{x} = \frac{1}{20}\\\\x= 20[/tex]
Hence,
The faster computer will complete the job in 20 minutes alone.
Given points A(2,1,3) and B(0,5,0), find a point C in the xy-plane that creates an isosceles right triangle such that:_______
a. AB and BC are the legs of the right triangle
b. AB is the hypotenuse of the right triangle (for part ii, just doing all the set-up work is sufficient; you do not need to solve and find the points)
Answer:
a.)Point C will be either (4.82, 7.41) or ( -4.82, 2.59)
b.) -x² + 2x + 6y - y² - 5= 0 , 8y - 4x = 11
Step-by-step explanation:
As given A(2,1,3) and B(0,5,0)
a.)
We have to find C in the xy-plane
⇒ C is of the form (x, y, 0) ( Because in xy plane , z coordinate is zero)
Now, given AB and BC are the legs of the right triangle .
AB = (0, 5, 0) - (2, 1, 3) = ( -2, 4, -3)
BC = (x, y, 0) - (0, 5, 0) = ( x, y-5, 0)
As AB and BC are legs of triangle
⇒AB is perpendicular to BC
⇒(AB).(BC) = 0
⇒( -2, 4, -3).( x, y-5, 0) = 0
⇒ -2x + 4(y-5) -0 = 0
⇒ -2x + 4y- 20 = 0
⇒ -x + 2y- 10 = 0
⇒ 2y = 10 + x
⇒ y = 5 + [tex]\frac{x}{2}[/tex] ......(1)
As ABC is making an isosceles right triangle
It means two sides of the triangle are equal
Now,
|AB| = √(-2)² + (4)² + (-3)² = √4+16+9 = √29
|BC| = √(x)² + (y-5)² + 0² = √(x)² + (y-5)²
Now,
AS AB = BC
⇒|AB| = |BC|
⇒|AB|² = |BC|²
⇒29 = (x)² + (y-5)²
⇒29 = (x)² + (5 + [tex]\frac{x}{2}[/tex] -5)²
⇒29 = (x)² + ( [tex]\frac{x}{2}[/tex] )²
⇒29 = x²( 1 + [tex]\frac{1}{4}[/tex] ) = x²( [tex]\frac{5}{4}[/tex] )
⇒ x² = [tex]\frac{116}{5}[/tex] = 23.2
⇒ x = 4.82 , -4.82
⇒y = 7.41 , 2.59
so, Point C will be either (4.82, 7.41) or ( -4.82, 2.59)
b.)
As given AB is the hypotenuse of the right triangle
S, AC and CB will perpendicular to each other
Now,
AC = (x, y, 0) - ( 2, 1, 3) = ( x-2, y-1, -3)
CB = (0, 5, 0) - (x, y, 0) = (-x, 5-y, 0)
As, AC and CB is perpendicular
⇒(AC).(CB) = 0
⇒( x-2, y-1, -3).(-x, 5-y, 0) = 0
⇒(x-2)(-x) + (y-1)(5-y) - 0 = 0
⇒-x² + 2x + 5y - y² - 5 + y = 0
⇒-x² + 2x + 6y - y² - 5= 0 ..........(2)
As ABC is making an isosceles right triangle
It means two sides of the triangle are equal
Now,
|AC| = √(x-2)² + (y-1)² + (0-3)² = √(x-2)² + (y-1)² + 9
|BC| = √(x)² + (y-5)² + 0² = √(x)² + (y-5)²
Now,
AS AC = BC
⇒|AC| = |BC|
⇒|AC|² = |BC|²
⇒(x-2)² + (y-1)² + 9 = (x)² + (y-5)²
⇒x² + 4 - 4x + y² + 1 - 2y + 9 = x² + y² + 25 - 10y
⇒ 4 - 4x + 1 - 2y + 9 = 25 - 10y
⇒14 - 4x - 2y = 25 - 10y
⇒10y - 2y - 4x = 25 - 14
⇒8y - 4x = 11 ........(3)
Now, we have 2 equations
-x² + 2x + 6y - y² - 5= 0 , 8y - 4x = 11
Solve these equations to find x, y

Find the length of side x in simplest radical form with a rational denominator.
Answer:
[tex] x = 6\sqrt{2}[/tex]
Step-by-step explanation:
Reference angle = 45°
Adjacent side = 6
Hypotenuse = x
Applying trigonometric ratio, we have:
[tex] cos(45) = \frac{6}{x} [/tex]
Multiply both sides by x
[tex] x*cos(45) = 6 [/tex]
Divide both sides by cos(45)
[tex] x = \frac{6}{cos(45)} [/tex]
[tex] x = \frac{6}{\frac{\sqrt{2}}{2} [/tex] (cos 45 = √2/2)
[tex] x = \frac{6}*{\frac{2}{\sqrt{2}} [/tex]
[tex] x = \frac{12}{\sqrt{2}} [/tex]
Rationalize
[tex] x = \frac{12*\sqrt{2}}{\sqrt{2}*\sqrt{2} [/tex]
[tex] x = \frac{12*\sqrt{2}}{2} [/tex]
[tex] x = \frac{6*\sqrt{2}}{1} [/tex]
[tex] x = 6\sqrt{2}[/tex]

iiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Answer:
[tex]x = \frac{5}{3}[/tex]
Step-by-step explanation:
The expression under the square root is [tex]\sqrt{4x^2 - 20x + 25}[/tex]
This is equivalent of [tex](2x-5)^2[/tex]
We can check this by using the formula
[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
where [tex]\\a = 2x so a^2 = (2x)^2 = 4x^2\\\\b = -5 so b^2 = (-5)^2 = 25\\\\2ab = (2)(2x)(-5) = -20x\\[/tex]
So
[tex]\sqrt{4x^2 - 20x + 25} = \sqrt{(2x-5)^2}[/tex] which is [tex](2x-5)[/tex]
(The square root of the square of an expression is the expression itself)
So that gives us
[tex]2x - 5 = 5-2x\\[/tex]
Collecting like terms on each side gives us
[tex]2x + 2x = 5 -(-5)\\\\4x = 10\\\\x = 10/4 = 5/3[/tex]
4x² when x = 5/6 and 1/2
