Answer:
3/10
Step-by-step explanation:
An hour is 60 mins
so the fraction would be 18/60
Then you can divide both numbers by 6 to 3/10

Alfred has 10 more tokens than Clarissa. Clarissa has twice as many tokens as Benji. They have 85 tokens altogether. How many tokens does each person have.
Answer:
Alfred has 40 tokens
Clarissa has 30 tokens
Benji has 15 tokens
Step-by-step explanation:
Let's give each person a variable:
A for Alfred
C for Clarissa
B for Benji
Now, we can take what the question is saying and convert them into equations:
Alfred has 10 more tokens than Clarissa can look like this:
A = C + 10
Since Alfred has 10 more coins than Clarissa we can take C and add 10 to find how many tokens Alfred has.
Clarissa has twice as many tokens as Benji looks like this:
C = 2B
Since Clarissa has twice as many tokens as Benji we can multiply B (how many tokens Benji has) by 2.
Lastly, they have 85 tokens all together:
A + B + C = 85
We have these 3 equations:
A = C + 10
C = 2B
A + B + C = 85
Now, we can substitute some variables:
A = (2B) + 10 Since C is equal to 2B we can substitute 2B in for C in the first equation.
We have found what A equals, we can plug that in to the last equation:
(2B) + 10 + B + C = 85
We can also substitute the second equation into the third equation:
(2B) + 10 + B + 2B = 85
Combine like terms:
5B + 10 = 85
Solve
5B = 75
B = 15
This means that Benji has 15 tokens. Now we can find how much the other children have:
C = 2(15) = 30
Clarissa has 30 tokens
A = 30 + 10
A = 40
Alfred has 40 tokens.
Answer:
Alfred has 40 tokens
Clarissa has 30 tokens
Benji has 15 tokens
Checking the Answer
A + B + C = 85
40 + 15 + 30 = 85
85 = 85

It is important for engineers design and building so understanding the relationship between the height and volume of the building. A taller building if not billed correctly is more likely to collapse, because a small increase in height leads to a large increase in volume. an engineer builds to build a models of different sizes in the shape of square blocks . the smaller building has a height of 1m, and volume of 1m^3. The volume of the larger building is 125m^3. The height of the building, represented by X, is equal to the cube root of the buildings volume. The equation below can be used to find X, in meters. X^3=volume determine how much taller, in meters, the height of the larger building is then the smaller building.Mm
Answer:
Larger building is 4 meters taller than smaller building.
Step-by-step explanation:
Formula to get the height 'x' of a building having volume = x³ is,
x = [tex]\sqrt[3]{\text{Volume of the building}}[/tex]
Height of the smaller building,
[tex]x_1=\sqrt[3]{1}[/tex]
[tex]x_1=1[/tex]
Similarly, height of the larger building = [tex]\sqrt[3]{125}[/tex]
= [tex]\sqrt[3]{5^3}[/tex]
= 5 meters
Difference in the heights of the buildings = 5 - 1
= 4 meters
Therefore, difference is the height of larger and smaller building is 4 meters.

Suppose someone gives you 6 to 1 odds that you cannot roll two even numbers with the roll of two fair dice. This means you win 6 dollars if you succeed and lose 1 dollar if you fail. What is the expected value of this game to you. What can you expect if you play 200 times
Answer:
0.75 ;
150
Step-by-step explanation:
Probability of rolling two even numbers :
{1, 2, 3, 4, 5, 6}
P(even) = 3 / 6 = 1/2
From a roll of 2 dice :
P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25
P(not even) = 1 - 1/4 = 3/4
X : ____ 6 _______ - 1
P(x) ____ 0.25 ____ 0.75
Expected value :
Σx*p(x) = (6*0.25) + (-1 * 0.75)
= 1.50 - 0.75
= 0.75
If 200 games are played :, n = 200
Expected value * n
0.75 * 200
= 150

In a coffee shop, the average drink is currently $4.50 while the average pastry is $2.25. You've made a total of $5,250 today. Write an equation to model the breakdown of your sales between drinks and pastries.
Answer:
[tex]4.50x+2.25y=5,250[/tex] where [tex]x[/tex] denotes number of drinks and [tex]y[/tex] denotes number of pastries.
Step-by-step explanation:
Let [tex]x[/tex] denotes number of drinks and [tex]y[/tex] denotes number of pastries.
Cost of the average drink = $4.50
Cost of the average pastry = $2.25
Total amount = $5,250
Therefore,
[tex]4.50x+2.25y=5,250[/tex]

Use Pascal's Triangle to help find the missing values. x^4-4x^b+6x^2-ax+1
a=
b=
Answer:
The value of a = 4 , b = 3
Step-by-step explanation:
Given the equation,
x⁴ - 4[tex]x^{b}[/tex] + 6x² - ax + 1
so, the coefficients are - 1 4 6 a 1
the Pascal's triangle is as follows :
1
1 2
1 2 1
1 3 3 1
1 4 6 4 1
So,
from Pascal's triangle ,
we can see that , after comparing with given equation , we get
Row n = 4
The coefficient be 1 4 6 4 1
∴ we get
a = 4
and
(x+y)⁴ = x⁴ + 4x³y + 6x²y² + 4xy³ + y⁴
Now, as given equation be x⁴ - 4[tex]x^{b}[/tex] + 6x² - ax + 1
By comparing we get y = -1 and b = 3
So, we get
a = 4 , b = 3
Brian's monthly gross income is $2,950. He pays 22% of his monthly gross
earnings in federal and state taxes and spends 10% of that monthly income to
pay off his credit card debt. Brian is also paying off a loan his parents gave him
for a new car by sending them 8% of his income per month. Brian found an
apartment near his work that rents for $1,300 per month. Will he be able to make
the payments without changing the amounts he pays towards his loan and credit
card debt?
Answer:
Yes
Step-by-step explanation:
I = 2950
T = 22% x 2950 = 649
CC = 10% x 2950 = 295
NC = 8% x 2950 = 256
R = 1300
I - (T + CC + NC + R) > 0
2950 - ( 649+ 295 + 256 + 1300) > 0
2950 - 2500 >= 0
450 > 0
