$45.63
Step-by-step explanation:
or all together
50,145 cm³ * 2.6 g/cm³ * 0.35/kg = $45.63
Apply slip and slide
a^2-3a-4
(a-4)(a+1)
(a-2)(2a+1)
Find zeros
a-2=0
a=2
2a+1=0
2a=-1
a=-1/2
Final answer: {-1/2, 2}
Answer:
(4500(Pi))/2 or 7068.585
Step-by-step explanation:
r = 15 cm
volume of a sphere:
(4/3)(Pi)r^3
Therefore:
(4/3)(Pi)15^3
15^3 = 3375
4/3 * 3375 = 4500
and since it is half a sphere (it is a bowl) the answer would be divided by two:
4500(Pi) divided by 2
14137.17 divided by 2
Answer:
Equation:
Solution:
Step-by-step explanation:
Let be "t" the number of movie tickets bought by the group of friends.
According to the information given in the exercise, the price of each movie ticket is: $8.50.
Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:
You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:
Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:
Finally, you can solve for "t" in order to find the solution of the equation. This is:
