Bobs car rental is offering a special of 40$ a day for a seden as long as you purchase the car damage protection insurance for 20$
Answers
In this case, we have a proportional relationship, since the cost varies directly with the days, this means that as x increases, y increases, and as x decreases, y decreases. A proportional relationship has the form:
y=kx
Where k is the constant of proportionality.
The ratio between them (x and y) is always the same, in this case, the ratio or constant of proportionality is 40, since each day the rent cost increases $40, then:
Constant of proportionality = 40 , replacing 40 for k into the above equation, we get:
equation: y = 40x
We can use this equation to find some pair of values (x,y) to fill the table, like this:
For x equals 2:
y= 40*2 = 80
For x equals 3:
y= 40*3 = 120
For x equals 4:
y=40*4 = 160
For x equals 5:
y=40*5=200
Then, we can fill the table as follows:
We can also use these data to graph the relationship, by taking the point (5,200) and joining it to the origin, we get:

Last year, Milan had $10,000 to invest. He invested some of it in an account that paid 6% simple interests per year, and he invested the rest in an account that paid 9% simple interest per year. After one year, he received a total of $840 in interest. How much did he invest in each account?
Answers
Let's define the next variables
x: amount of money invested in one account
y: amount of money invested in the other account
Milan had $10,000 to invest, then
x + y = 10000 (eq. 1)
The interest Milan gets after one year are: 0.06x and 0.09y. He received a total of $840 in interest, then
0.06x + 0.09y = 840 (eq. 2)
Isolating x from equation 1:
x = 10000 - y
Replacing this result into equation 2,
0.06(10000 - y) + 0.09y = 840
0.06(10000) - 0.06(y) + 0.09y = 840
600 + 0.03y = 840
0.03y = 840 -600
0.03y = 240
y = 240/0.03
y = 8000
Then,
x = 10000 - y
x = 10000 - 8000
x = 2000
He invested $2000 in the account that paid 6% simple interests per year and $8000 in the account that paid 9% simple interests per year

Answers
In linear equation, Equation for line F is y = 1.75x + 3.5 and equation for line G is y = -4x-8.
What is a linear equation example?
Ax+By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x+3y=5.Finding both intercepts of an equation in this format is rather simple (x and y).y = 1.75x + 3.5 (For line F)
let's take the point (2,7) and put in the equation,
y = 1.75*2 + 3.5
= 3.5 +0.35
= 7
which is true.
Hence, (2,7) satisfies the equation.
y = -4x-8 (For line G)
lets take the point (-3,4) and put in the equation,
y = (-4)*(3) - 8
= 12 - 8
= 4
which is true.
Hence, (-3,4) satisfies the equation.

Two sides of a triangle have the same length. The third side measures 3 m less than twice the common length. The perimeter of the triangle is 17 m. What are the lengths of the three sides? What is the length of the two sides that have the same length? m
Answers
Let the common sides have length x, i.e, we have 2 sides measuring x
the third side would measure 2x - 3.
The perimeter = x + x + 2x - 3 = 4x - 3 = 17
so, 4x = 17 + 3 ,
4x = 20
x = 20/4 = 5m

1) The first thing we need to do in this question, is to find the sample space, i.e. the total number of outcomes, in this case, fishes.
[tex]262+382+181+336+190=1351[/tex]2) Since no one could pick simultaneously two types of fish, then we can tell that these events are mutually exclusive. So, we can write the following:
[tex]\begin{gathered} P(flounder)=\frac{262}{1351} \\ \\ P(black\:drum)=\frac{181}{1351} \\ \\ P(red\:drum)=\frac{382}{1351} \\ \\ P(drum\:or\:flounder)=\frac{262}{1351}+\frac{181}{1351}+\frac{382}{1351}=\frac{825}{1351}\approx0.6107 \end{gathered}[/tex]Note that by "drum" we are including black and red drum.
