Find an equivalent expression for: 20+5(2x+5)
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

i took the test on k12
Solve this equation:
5x^4+ 50x^2 +80=0
Answer:
x =√-1.403 = 0.0 - 1.18454 i
x =√-1.403 = 0.0 + 1.18454 i
x =√11.403 = -3.37685
x =√11.403 = 3.37685
Step-by-step explanation: i think either one of these could work

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]
Hope I helped ! ♡

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.
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
SOLVE FOR Y, WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
1. As you can see in the picture, x is 116 degrees, because that angle and the angle labeled 116 degrees are corresponding, meaning that their angles are the same.
2. As you can also see in the picture, y+11+x = 180 deg, because they are two angles that make a straight angle. We know that x is 116 deg, so we can solve y with an equation:
y + 11 + 116 = 180
y + 127 = 180
y = 180 - 127
y = 53 degrees.

g. x+2
h.(x+5/x+2) ( x+2/x+5) Number 3
Answer
Factorizing the expressions (x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)
=(x²+ 5x+2x+ 10/ x²+ 2x+2x+4 ) (x²+ 2x+x+ 2/x²+ 5x+x+5)
Taking common
=[x(x+5) +2(x+5)/ x(x+2) +2(x+2) ] [ x(x+2) +1(x+2)/ x((x+5) +1(x+5)]
Putting commons together
=[(x+2) (x+5)/ (x+2) (x+2)] [ (x+2)(x+1)/ (x+1) (x+5)]
Cancelling
= [ (x+5)/ (x+2)]* [ (x+2)/ (x+5)]
=[ (x+5)/ (x+2)] [ (x+2)/ (x+5)]
Again Cancelling
=1
The above question is solved in 4 steps :
Step 1
(x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)
Step 2
(x+5/x+2) * ( x+2/x+5)
Step 3
(x+5/x+2) ( x+2/x+5)
Step 4
1 which is the answer .
The steps
(x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2) ,
(x+5) ( x+2) /(x+5),
(x+7/x+4) ( x+1/x+2) and (x+2) are not related to this question.

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.
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been folling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
Answer:
Step-by-step explanation:
This question is incomplete; here is the complete question.
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
If it continues to fall at this rate, what will the temperature be:
In 2 hours ............. In 5 hours .............. In half an hour......................
If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.
Then after 'x' hours, temperature on the top of the mountain will be represented by the function,
T(x) = 0 - 3x
Therefore, temperature after 2 hours = -3(2) = -6°C
Temperature after 5 hours = -3(5) = -15°C
Temperature after half an hour = [tex]-3(\frac{1}{2})[/tex]
= -1.5°C

From inspection on the given problem:
[tex]\sf (x_1, y_1) = (-3, -4)[/tex][tex]\sf (x_2, y_2) = (4, 5)[/tex]Substitute the given values into the distance formula and solve for AB:
[tex]\sf AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf AB = \sqrt{[4 - (-3)]^2 + [5 - (-4)]^2}[/tex][tex]\sf AB = \sqrt{(7)^2 + (9)^2}[/tex][tex]\sf AB = \sqrt{49 + 81}[/tex][tex]\bold{AB = \sqrt{130} \approx 11.4 \: units}[/tex]Therefore, the distance between two points is [tex]\sqrt{130}[/tex] or 11.4 units.
