Answer:
1085/3 = 361.7
Step-by-step explanation:
Expand −8.68/0.024 ≈361.666666667 by multiplying both numerator and the denominator by 1000.
8680/-24 ≈361.666666667
Reduce the fraction −8680/24≈361.666666667 to lowest terms by extracting and canceling out −8.

Donovan spent 2/15 hour walking to the mailbox, 1/6 hour walking to the library, and 2/10 hour walking to the park. Which took Donovan the longest amount of time to walk to? Explain.
Answer:
The walk to the park took the longest amount of time
Step-by-step explanation:
In this question, we want to find the location that took Donovan the longest amount of time to work.
We should recall that an hour is 60 minutes
So time spent walking to the mailbox would be 2/15 * 60 = 8 minutes
Time spent walking to the library would be 1/6 * 60 = 10 minutes
Time spent walking to the park = 2/10 * 60 = 12 minutes
So as we can see, the distance taking the longest amount of time to walk is the Park which took a total of 12 minutes

Micheal is 5 years older than Rui Feng and Vishal is thrice as old as Micheal if Rui Feng is p years old, find i) Michael's present age, ii) Vishal's present age, ii) the sum of there age in 6 age years time, iv) the sum of their ages 3 years ago.
Answer:
Michael's present age = p + 5
Michael's present age = 3p + 15
Sum of there ages 6 year age = 5p + 38
Sum of there ages 3 year ago = 5p - 11
Step-by-step explanation:
Assume;
Age of Rui Feng = x
Age of Micheal = x + 5
Age if Vishal = 3[x+5]
Given:
Age of Rui Feng = P
Computation:
Michael's present age = Age of Rui Feng + 5
Michael's present age = p + 5
Vishal's present age = 3[p + 5]
Michael's present age = 3p + 15
Sum of there ages 6 year age = [p + 6] + [p + 5 + 6] + 3[p + 5] + 6
Sum of there ages 6 year age = 5p + 38
Sum of there ages 3 year ago = [p - 3] + [p + 5 - 3] + 3[p + 5] - 3
Sum of there ages 3 year ago = 5p - 11

160+3x=195-2x what is the answer
Answer:
x = 7
Step-by-step explanation:
160+3x=195-2x
Add 2x to each side
160+3x+2x=195-2x+2x
160 +5x = 195
Subtract 160 from each side
160+5x-160 = 195-160
5x = 35
Divide by 5
5x/5 = 35/5

10. Jack and Jill were working on their homework together but ended up with two different
answers to the same problem. The problem asked for a new line, parallel to y=2x+3, and
containing the point (-2,-2). Who got the problem correct? Explain your reasoning?
Jack:
y-2 = 2(x - 2)
y-2 = 2x - 4
y = 2x - 2
Jill:
y + 2 = 2(x + 2)
y + 2 = 2x + 4
y = 2x + 2
Answer:
Explanation:
Step-by-step explanation:
Hey there!
Firstly we need to find an equation of the line passing through point (-2,-2).
Now,
The equation of a st.line passing through point (-2,-2) is,
[tex](y - y1) = m1(x - x1)[/tex]
Now, putting the values,
[tex](y + 2) = m1(x + 2)[/tex]
It is first equation.
Now, another equation is,
y= 2x+3
Comparing, the equation with y = mx+c.
slope (m2)= 2
As per the condition of parallel lines,
m1=m2= 2
Putting, the values of m1 in equation (i)
(y+2)= 2(x+2)
y= 2x+2....is the equation.
Therefore, Jill's equation is correct answer.
Hope it helps...

want to make confetti. In order to get the right balance of ingredients for their tastes they bought 2 pounds of paper hearts at $ 3.42 per pound comma 2 pounds of sparkling stars for $ 3.93 per pound comma and 5 pounds of shiny coils for $ 2.53 per pound. Determine the cost per pound of the confetti.
Answer:
$3.039
Step-by-step explanation:
Step 1
They bought 2 pounds of paper hearts at $ 3.42 per pound
1 pound = $3.42
2 pounds =
2 × $3.42
= $6.84
2 pounds of sparkling stars for $ 3.93 per pound
1 pound of sparking stars = $3.93
2 pounds =
$3.93 × 2
= $7.86
5 pounds of shiny coils for $ 2.53 per pound.
1 pounds of shiny coils = $2.53
5 pounds =
5 × $2.53
= $12.65
Step 2
We find the total cost of the materials
Total cost of Materials that make up the confetti = Cost of paper heart + Cost of sparkling stars + Cost of shiny coils.
= $6.84 + $7.86 + $12.65
= $27.35
Step 3
Total pounds of materials bought = 2 pounds + 2 pounds + 5 pounds
= 9 pounds
Step 4
The cost per pound of confetti = Total cost of the materials bought/ Total pounds of materials
= $27.35/9
= $3.0388888889
Approximately ≈ $3.039
The cost per pound of the confetti = $3.039
The cost per pound of the confetti is $3.04
Total cost :Given that, they bought 2 pounds of paper hearts at $ 3.42 per pound.
The cost of 2 pounds of paper hearts is, [tex]=2 *3.42=6.84[/tex]
the 2 pounds of sparkling stars for $ 3.93 per pound
The cost of 2 pounds of sparkling stars is, [tex]=$3.93 * 2=7.86[/tex]
the 5 pounds of shiny coils for $ 2.53 per pound.
The cost of 5 pounds of shiny coils is, [tex]=5 * $2.53=12.65[/tex]
Total cost of confetti is,
[tex]= $6.84 + $7.86 + $12.65=27.35[/tex]
Total pounds of materials bought ,
[tex]=2+2+5=9pounds[/tex]
The cost per pound of confetti is,
[tex]=\frac{27.35}{9}=3.04[/tex]
The cost per pound of the confetti is $3.039

Which table has a constant of proportionality between y and x of 8/5
Answer:
Table 1
Step-by-step explanation:
Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.
Table 1:
4 32/5
10 16
11 88/5
Let's find the constant of proportionality for each row:
R1: (32/5) / 4 = 8/5
R2: 16/10 = 8/5
R3: (88/5) / 11 = 8/5
Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.
If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.

Answer:
V= -8/29
Step-by-step explanation
-3(-9v-4), -3 makes -9 and -4 positive cause neg times neg equals a positive
same goes for -2(v-2) so your new equation is 27v+12-2v+4
minus 12 from both sides which gives you -8 and add 2v on both sides which gives you 29v and you divided the two new numbers and you get -8/29
