solve for k 6=2-k for math :) i needa hurry and get it done
Answer:
-4 is the correct ans
hope it helps
Step-by-step explanation:
[tex] \tt{6 = 2 - k}[/tex]
~Swap the sides of the equation
⟶ [tex] \tt{2 - k = 6}[/tex]
~Transpose 2 to right hand side and change it's sign
⟶ [tex] \sf{ - k = 6 - 2}[/tex]
~Subtract 2 from 6
⟶ [tex] \tt{ - k = 4} [/tex]
~Divide both sides of the equation by -1
⟶ [tex] \tt{ \frac{ - k}{ - 1} = \frac{4}{ - 1}} [/tex]
⟶ [tex] \tt{k = - 4}[/tex]
[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{k = - 4}}}}}}}[/tex]

If a snowball melts so that its surface area decreases at a rate of 7 cm2/min, find the rate at which the diameter decreases when the diameter is 8 cm. cm/min
Answer:
7/16π
Step-by-step explanation:
The surface area of the snow ball = 4πr^2
Let the surface area= y
Then y= 4πr^2
The derivative can be taken with respect to time as
dy/dt= (8πr)dr/dt...........eqn(1)
We were told that its surface area decreases at a rate of 7 cm2/min.
Then dy/dt=-7
diameter = 8 cm. cm/min, the radius r= 4cm/min
r= 4
Substitute the values of r into eqn(1)
dy/dt=(8π×4)dr/dt
-7=(32π) dr/dr
dr/dt= -7/32π................eqn(**)
But we know that diameter d= 2× radius
d=2r............eqn(*)
We can find the derivatives with respect to t as
dd/dt=2dr/dt
Then substitute en(**) we have
dd/dt=2(7/32π)
dd/dt= -14/32π
Divide both numerator and denominator by 2
dd/dt= -7/16π
Hence, the diameter decreases by the rate of 7/16π

Each unit in the graph above is one mile. How far would you have to drive from the art gallery to the dry cleaners and then continue on to the theater?
A) 12 miles
B) 11 miles
C) 10 miles
D) 5 miles
Answer:
Option C i.e. 10 miles is true.
Step-by-step explanation:
From the graph, it is clear that:
The art gallery is located at x = 7 and y = 2
The dry cleaners is located at x = 7 and y = 7
The theater is located at x = 2 and y = 7
Given that each unit is 1 mile.
Distance from the art gallery to dry cleaners is on the vertical path.
so
Distance from art gallery to dry cleaners = 7 - 2 = 5 miles
As Theater and dry cleaners are on the horizontal path.
Thus, in order to move to the theater from dry cleaners, all we need is to count the unit on the x-axis from x = 7 to x = 2.
i.e. 7 - 2 = 5 miles
Thus, the total distance: 5 + 5 = 10 miles
Therefore, option C i.e. 10 miles is true.
Write 4 4/7 as an improper fraction.
Answer:
32/7
Step-by-step explanation:
4/47
you multiply the denominator by the whole number which is 7*4= 28. You then add the numerator to 28 which is, 28+4=32.
the improper fraction is: 32/7
4 4/7 can be written as 32/7 in improper fraction.
To solve this problem4 4/7 is a mixed number. It is possible to write it as follows:
4 + 4/7
The mixed number's first component, 4, is a whole number. The fractional portion of the mixed number is the second component, 4/7.
We must change the whole number component of 4 4/7 into a fraction with the same denominator as the fractional component in order to write it as an improper fraction. The denominator in this situation is 7. The result of the conversion is 4 * (7/7) = 28/7.
Now, we have:
28/7 + 4/7
Now, we just add the two fractions and simplify:
= 32/7
Therefore, 4 4/7 can be written as 32/7 in improper fraction.

What is equivalent distance of 35,000 centimeters in kilometers?
1 km = 1000 m
1 m = 100 cm
Enter your answer in the box.
Answer:
0.35km
Step-by-step explanation:
What is equivalent distance of 35,000 centimeters in kilometers?
Given the following
1 km = 1000 m
1 m = 100 cm
If
1 m = 100 cm
x = 35000cm
100x = 35000
x = 35000/100
x = 350m
Convert 350m to km
1 km = 1000 m
x = 350m
1000x = 350
x = 350/1000
x = 0.35km
Hence 35000cm to km is 0.35km
Answer:
0.35

A department store buys 100 shirts at a cost of $700 and sells them at a selling price of $10 each. Find the percent markup.
Answer:
42.8%
Step-by-step explanation:
Step one:
given data
A department store buys 100 shirts at a cost of $700
let us find the cost of 1 shirt
cost of 1 shirt= 700/100= $7 per shirt
The cost price per shirt = $7
We are given that the selling price = $10 per shirt
Step two:
The percent markup can be found as
percent markup= selling-cost price/cost price*100
percent markup= 10-7/10*100
percent markup= 3/7*100
percent markup= 0.428*100
percent markup= 42.8%

How do I get my parents to let me quit extra math (RSM) even after I've tried for a while
please help me.
Maybe offer to make a deal with them where if you get all A's in your normal classes you can quit. It really depends on why you're taking the class in the first place. If it's not affecting your grades in any way, maybe it's best to just stay for the benefits of it.
