The probability of drawing a 7 or 8 from a decl of playing cards is 2/13.
Given that y varies directly with x and inversely with z, then:
a] Equation that models the relationship
y=kx/z
where k is the constant of proportionality, given by:
k=yz/x
k=(28×8)/32
k=7
The equation that models the relationship is:
y=7x/z
b]
<span>find y when x = 12 and z = 3
The value of y will be given:
y=(7</span>×12)/3
<span>y=28

Hi!
The first thing I would do is see how much the charity has to make to exceed its goal. To do that, I would subtract how much they've already made from their goal.
1200 - 750 = 450
Now, since each ad provides 25 dollars, and the charity wants to exceed its goal, add 25 to 450, to get 475. (What they have to make to exceed their goal)
Now, just find how many ads must be made, or how many 25 dollars, go into 475, by dividing 475 by 25.
475/25 = 19 ads
Of course, if you get this question wrong and instead its 18 because your teacher stated they weren't supposed to exceed the goal and instead just meet it, you can question their wording of the problem.
Hope this helped!
90-40=50: $90 dollars total. $40 dollars of that is the the cost so you have $50 dollars to find out.
$50÷$2=25: You have $50 dollars left and each visit is $2 so you went 25 times.
Answer:
x+ x×3%×11/2=19513.75 considering 3% interest per year for 5 and a half years
x=8375
Step-by-step explanation:
x×233/200=19513.75
x=1951375/233
x=8375
