3x = 90
x = 30
∠MKN = 30°
You have a friend that feels tired so often that they use coffee to try to waken themselves up in the afternoon. They typically drink a venti Starbucks coffee at 4:00 pm in the afternoon. They go to bed around 10:00 pm must wake up at 6:00 am. You’re concerned that drinking the coffee may be affecting their sleep habits and using coffee to solve the problem is only making it worse.
•The amount of caffeine in a venti Starbucks coffee is 415mg
•Every hour, the amount of caffeine in your body decreases by 12%
•People that have 300mg of caffeine at bedtime experience severe sleep disruption
•People that have 50mg of caffeine at bedtime can experience a loss of one hour of sleep
•Recommend sleep time for teenagers is 8-10 hours
Create a report to determine if your friend needs to change their coffee drinking habits.
Answer:
Not sure how to answer that but i am that friend getting a venti strabucks everyday and i go to sleep at 4-6 am and wake up at sometime between 10-1 pm

Equation to solve for "x": 90 + x + x + 18 = 180
x = 36
Step-by-step explanation:
90 + x + x + 18 = 180
90 + 18 + 2x = 180
108 + 2x = 180
(108 - 108) + 2x = 180 - 108
2x = 72
2x/2 = 72/2
x = 36
90 + 36 + 36 + 18 = 180
108 + 72 = 180
180 = 180

3. A cubical wooden box has a surface area of 600 square cm. What is the measurement
of each
edge?
B. 6 cm
C. 10 cm
A. 5 cm
D. 100 cm
Answer:
C)
B)
C)
Step-by-step explanation:
Question-1:recall the surface area formula of cylinder
[tex] \displaystyle A _{S} = 2\pi r(h + r)[/tex]
given that,h=5 and r=0.7
substitute:
[tex] \displaystyle A _{S} = 2\pi (0.7)(5 + 0.7)[/tex]
simplify parentheses:
[tex] \displaystyle A _{S} = 2\pi (0.7)(5 .7)[/tex]
simplify multiplication:
[tex] \displaystyle A _{S} =25.0572 sqm[/tex]
hence, our answer is C
Question-2:remember the surface area formula of cone
[tex] \displaystyle A _{S} = \pi r(r + s)[/tex]
given that,r=7 and s=10
substitute:
[tex] \displaystyle A _{S} = \pi (7)(7+ 10)[/tex]
simplify parentheses:
[tex] \displaystyle A _{S} = \pi (7)(17)[/tex]
simplify multiplication:
[tex] \displaystyle A _{S} =373.66sqcm[/tex]
hence, our answer is B
Question-3:now for the question-3 we need a little bit understanding
remember the surface area formula of cube
[tex] \displaystyle A _{S} =6 {a}^{2} [/tex]
we are given that,[tex]A_S=600[/tex] Thus
substitute:
[tex] \displaystyle 6 {a}^{2} = 600[/tex]
divide both sides by 6:
[tex] \displaystyle {a}^{2} = 100[/tex]
square root both sides:
[tex] \displaystyle {a}^{} = 10[/tex]
hence, the measurement of each
edge is 10 cm therefore our answer is C)
what is the value of y in the following system of equations ? 2x + 3y = 6 2x + y = -2
y = 4
Step-by-step explanation:
2x + 3y = 6. #1
2x + y = -2. #2
Subtract Eq 2 from Eq 1,
3y - y = 6 - (-2)
2y = 8
or
y = 4
Answer:
y = 4
Step-by-step explanation:
2x + 3y = 6
2x + y = -2
Let's set the second equation equal to y. This means that y will be alone on one side of the equal sign.
2x + y = -2
Subtract 2x from both sides.
y = -2x - 2
Now that we have y as an expression, plug it into the first equation.
2x + 3y = 6
2x + 3(-2x - 2) = 6
Distribute the 3 across the parentheses by multiplying.
2x - 6x - 6 = 6
Combine like terms.
-4x = 12
Divide both sides by -4.
x = -3
Now we have solved x.
To solve for y, plug x back into one of the equations.
y = -2x - 2
y = -2(-3) - 2
Multiply.
y = 6 - 2
Subtract.
y = 4
Check your answer by plugging both values back into the original equations.
2x + 3y = 6
2(-3) + 3(4) = 6
Multiply.
-6 + 12 = 6
Add.
6 = 6
Your answer is correct.
Hope this helps!

Answer:
Exact Area = 210.25pi - 210Approximate Area = 450.185The units for the area are in square inches or in^2. The approximate value shown above is when using pi = 3.14
=============================================================
Explanation:
Use the pythagorean theorem to find the length of the hypotenuse
a = 20b = 21c = unknowna^2 + b^2 = c^2
20^2 + 21^2 = c^2
400 + 441 = c^2
c^2 = 841
c = sqrt(841)
c = 29
The hypotenuse is 29 inches long. This is the diameter of the circle. Half of that is the radius at r = d/2 = 29/2 = 14.5 inches.
The area of the circle is...
A = pi*r^2
A = pi*(14.5)^2
A = pi*210.25
A = 210.25pi
Which is exact in terms of pi
We'll subtract off the triangular region as this isn't shaded in. The area of the triangle is base*height/2 = 20*21/2 = 420/2 = 210 square inches.
So the shaded region is therefore 210.25pi - 210 square inches
This approximates to 210.25*3.14 - 210 = 450.185 when using the approximation pi = 3.14; use more decimal digits of pi to get a more accurate value.

Step-by-step explanation:
1- The acceleration of a particle is defined by the relation a = 6 ft/s 2. Knowing
that s =-32 ft when t = 0 and v= -6 ft/s when t = 2 s, determine the velocity, the
position, and the total distance traveled when t = 5 s.
help fast
Answer:
The initial velocity of the particle is
v' = -6 - 6.2 = -18 ft/s
at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s
the position is
[tex]x = - 32 - 18 \times 5 + \frac{1}{2} \times 6 \times 5 {}^{2} = - 47 \: ft[/tex]
the total distance traveled is
[tex]s = | \frac{12 {}^{2} - 18 {}^{2} }{2 \times 6} | = 15 \: ft[/tex]
Gavin wants to buy a bike which costs 1,000 dollars. He raised 250 so far from his shoe shop. How much more does Gavin need to raise in order to buy the bike?
Answer:
the answer would be 750 dollars.
Step-by-step explanation:
If he needs $1,000 in total and already has $250, you can do 1,000 - 250 to get 750. A simpler way to.do that could be to take 1,000 - 200 to get 800, and then subtract another 50.
