Unless you just want to give money to the ice cream truck, for 0 items, you will pay 0.
Since the price of each item is $0.77, for one item you will pay $0.77. (Is that a surprise?)
Then for two items, you will pay $0.77 for each one, or $0.77 + 0.77 = $1.54. You can also compute this by making use of the fact that multiplication is a shortcut for repeated addition. The price can be found by $0.77×2 = $1.54 = f(2).
Similarly, for 3 items, you can add $0.77 three times: $0.77 + 0.77 + 0.77 = f(3), or you can use multiplication: $0.77×3 = $2.31 = f(3).
a) Our table looks like
(x, f(x))
(0, 0)
(1, 0.77)
(2, 1.54)
(3, 2.31)
b) By now, I'm sure you have realized that to find the price of x items, you multiply 0.77 by x.
f(x) = 0.77x
250/100 = 2.5
2.5*7 = 1.75
$1.75
Hope this helped!
Answer:
Equation 1 x=-16
Equation 2 m=-3
Step-by-step explanation:
Equation 1
3x-x=-24-6
2x=-32
x=-32/2
x=-16
Equation 2
-2m=16-10
-2m=6
m=6/-2
m=-3
Answer:
Hemisphere radius = 3 inch
Sphere volume = 4/3 • π • radius^3
Sphere volume = 4/3 • π • 27
Sphere volume = 113.0973355292 cubic inches
Cylinder Volume = π • radius^2 • height
Cylinder Volume = π • 9 * 10
Cylinder Volume = 282.7433388231 cubic inches
TOTAL VOLUME = 113.10 + 282.74 cubic inches
TOTAL VOLUME = 395.84 cubic inches
Step-by-step explanation:
a.
Sally has $28.00 in her bank account and starts saving $18.25 every week.
Let x represent the number of weeks from when he have $28.00 in her account.
and y represent the amount in her account at week x;
We can write the function of the case as;
where m is the amount she saves every week, and b the initial amount in her account.
So, the function will be;
b.
Her friend Suzy has $161.00 in her bank account and is withdrawing $15 every week.
Using the same rule as in a above;
The function will be;
c.
The graph of the two functions is shown below;
d.
The point where the two lines intersect is shown in the graph above.
The point is at;
Which is at week 4 and balance $101.
e.
The point at which they intersect is the point where they both have the same values.
It is the week when both Sally and Suzy have the same amount in there account.
So, at the fourth week (week 4) Sally and Suzy both have $101 in their account
