Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his sister runs after him with his lunch, averaging 6mi/h.
Answers
Complete question :
Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his sister runs after him with his lunch, averaging 6mi/h. Determine take it takes for sister to catch up
Answer:
5 minutes
Step-by-step explanation:
Ray's rate = 2mi/ hr
Time walked before sister starts = 10 minutes = (10/60) = 0.16667 hours
Hence, distance already covered = (rate * time) = (2 * 0.16667) = 0.3333 miles
To catchup :
Let t = Time taken to catch ; At t, distance covered must be the same ; thus ;
0.3333 + (2 * t) = 6 * t
0.3333 + 2t = 6t
0.3333 = 6t - 2t
0.3333 = 4t
t = 0.3333 / 4
t = 0.0833333 hours
t = 0.0833333 * 60 = 5 minutes

Norma is looking for a job cutting hair. One option is self-employment at The Seaside Salon, where she would pay $534 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $3 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Norma pay?
If Norma performed__________ haircuts in a month, she would pay $____________ to either salon.
Answers
Answer:
If Norma performed 178 haircuts in a month, she would pay $534 to either salon
Step-by-step explanation:
Saloon 1:
Cost of saloon 1 = $534
Saloon 2:
Cost of saloon 2 = 3h
Where,
h = number of haircut
Equate the cost of renting either saloon
534 = 3h
h = 534 / 3
h = 178 hair cut
If Norma performed 178 haircuts in a month, she would pay $534 to either salon.
Joseph has a collection of stickers. When the stickers are aranged in piles of 3, there are 2 stickers left over. When the stickers are aranged in piles of 4, there are 2 stickers left over. When the stickers are arranged in piles of 12, how many stickers are left over?
Answers
Answer:
2 stickers will be left over
Step-by-step explanation:
To answer the question, all you need to do is figure out at what value of stickers would the remaining stickers be equal to 2 if the piles are made up of either 3 to a set or 4 to a set. To do this, we need to figure out the size of the whole set of stickers.
Lets assume that the total number of stickers is 14. Lets test the 2 given conditions. If we divide it in piles of 3 then we will have a pile of 12 stickers (4 piles of 3 stickers each) with 2 stickers remaining.
Lets test the second condition. If we divide it in piles of 4, we will again have 12 stickers (3 piles of 4 stickers each) with 2 stickers remaining.
Now that both conditions have been satisfied, all we have to do is see how many stickers are left if we make a pile of 12 stickers. In this case, we will have just one pile of 12 stickers and, again, we will be left with 2 stickers.
Therefore, the answer is 2 stickers

-6x – 3y = 24
4x – 2y = 8
Answers
Answer:
The solution of the system is:
(x, y) = (-1, -6)
Step-by-step explanation:
Given the system of equations
-6x – 3y = 24
4x – 2y = 8
solving the system of equations
[tex]\begin{bmatrix}-6x-3y=24\\ 4x-2y=8\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}-6x-3y=24\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-12x-6y=48[/tex]
[tex]\mathrm{Multiply\:}4x-2y=8\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:12x-6y=24[/tex]
so
[tex]\begin{bmatrix}-12x-6y=48\\ 12x-6y=24\end{bmatrix}[/tex]
adding the equations
[tex]12x-6y=24[/tex]
[tex]+[/tex]
[tex]\underline{-12x-6y=48}[/tex]
[tex]-12y=72[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}-12x-6y=48\\ -12y=72\end{bmatrix}[/tex]
solve -5y=72 for y
[tex]-12y=72[/tex]
Divide both sides by -12
[tex]\frac{-12y}{-12}=\frac{72}{-12}[/tex]
Simplify
[tex]y=-6[/tex]
[tex]\mathrm{For\:}-12x-6y=48\mathrm{\:plug\:in\:}y=-6[/tex]
solving
[tex]-12x-6\left(-6\right)=48[/tex]
[tex]-12x+6\cdot \:6=48[/tex]
[tex]-12x+36=48[/tex]
subtract 36 from both sides
[tex]-12x+36-36=48-36[/tex]
Simplify
[tex]-12x=12[/tex]
Divide both sides by -12
[tex]\frac{-12x}{-12}=\frac{12}{-12}[/tex]
[tex]x=-1[/tex]
Therefore, the solution of the system is:
(x, y) = (-1, -6)
Solve (x – 3)^2 = 49. Select the values of x.
–46

52
Answers
Answer:
10
Step-by-step explanation:
The solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.
To solve the equation (x - 3)² = 49, we can take the square root of both sides of the equation to eliminate the squared term.
√[(x - 3)²] = √49
Taking the square root of a square cancels out the exponent, resulting in:
|x - 3| = 7
Now, we have two cases to consider:
x - 3 = 7
In this case, we add 3 to both sides:
x = 7 + 3
x = 10
-(x - 3) = 7
Here, we distribute the negative sign:
-x + 3 = 7
Then, subtract 3 from both sides:
-x = 7 - 3
-x = 4
To isolate x, multiply both sides by -1, remembering to flip the inequality:
x = -4
Therefore, the solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.
Answers
Answer:
When y=32, x=16.5
Step-by-step explanation:
Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.
We are given:
x varies inversely with y
We can write it as: [tex]x\:\alpha \:\frac{1}{y}[/tex]
[tex]x=\frac{k}{y}[/tex]
We have x = 132, when y=4
We can find value of k by using these values
[tex]x=\frac{k}{y}\\132=\frac{k}{4}\\k=132*4\\k=528[/tex]
We need to find x when y=32
[tex]x=\frac{k}{y}\\x=\frac{528}{32}\\x=16.5[/tex]
So, when y=32, x=16.5
