Since the distances were the same you can find the average speed directly by adding the speeds then dividing by 2. No need to weight anything.
If we’re considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
However if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
Depending on the context, either of these could be your answer.
Answer:
19.2
Step-by-step explanation:
You have to trust me, this answer is correct. But here's my solution:
With the formula
Distance=Speed multiplied by Time, we can infer that Speed=Distance/Time.
But we only have one variable (Speed) in the two we need (Speed and Time), we have to pretend we have both variables. You can put the time as 1 hour, because that's the most basic unit. Note that this strategy will also work with 2 hours, 3 hours, or any measure of time.
So now for distance, let's see how fast a car can travel 24 miles. When going at 24 mph, then it'll take 1 hour. With 16 mph, then it'll take 1 hour and 30 minutes, so 1.5 or 3/2 hours.
Now we have the distance, which is 2 times 24 (Because the 24 mph and 16 mph both traveled 24 miles), equaling 48, and time, which is 1 hour plus 1.5 hours, which is 2.5 hours.
Now we use the formula Speed=Distance/Time, with 48/2.5=19 1/5 or 19.2

Find the surface area of a cube
with side length 8.5 cm.
=========================================================
Explanation:
A cube has 6 identical faces, all of which are squares.
Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.
The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm
Answer:
A=433.5cm²
Step-by-step explanation:
A=6a2=6·8.52=433.5cm²

right angle triangle
opp=18cm
hyp=16cm
find the missing side which is x
Step-by-step explanation:
Step 1: find the names of the two sides we know
triangle showing Opposite, Adjacent and Hypotenuse
Adjacent is adjacent to the angle,
Opposite is opposite the angle,
and the longest side is the Hypotenuse.
Example: in our ladder example we know the length of:
the side Opposite the angle "x", which is 2.5
the longest side, called the Hypotenuse, which is 5
Step 2: now use the first letters of those two sides (Opposite and Hypotenuse) and the phrase "SOHCAHTOA" to find which one of Sine, Cosine or Tangent to use:
SOH...
Sine: sin(θ) = Opposite / Hypotenuse
...CAH...
Cosine: cos(θ) = Adjacent / Hypotenuse
...TOA
Tangent: tan(θ) = Opposite / Adjacent
In our example that is Opposite and Hypotenuse, and that gives us “SOHcahtoa”, which tells us we need to use Sine.
Step 3: Put our values into the Sine equation:
Sin (x) = Opposite / Hypotenuse = 2.5 / 5 = 0.5
Step 4: Now solve that equation!
sin(x) = 0.5
Next (trust me for the moment) we can re-arrange that into this:
x = sin-1(0.5)
And then get our calculator, key in 0.5 and use the sin-1 button to get the answer:
x = 30°

How do I solve
-3x+y=24
-2x=+18+5y
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1
Step-by-step explanation: that is your anwser

Maggie drew triangle and then triangle . Triangle is congruent to triangle only if ∠ is equal to what value?
Include explanation!!
Answer:
Angle ABE = 58
Step-by-step explanation:
This would fulfill the AAA theorem, or 3 angles needing to be congruent. We got 58 by subtracting 89 and 62 from 180, then multiplying that answer by 2 (because it occupies both triangles).

the midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y
Answer:
(x,-y): (2,-2)
Step-by-step explanation:
M=(x+x)/2,(y+y)/2
Given (1,4)=
[tex] \frac{3x - 4}{2} [/tex]
This implies:
[tex]1 = \frac{3x - 4}{2} [/tex]
[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]
In a similar way,
[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]
The question demanded (x,-y)
Hence(2,-2) is the answer

One challenge of federalism is that
power and authority are concentrated in the central government and can take away people’s rights
sometimes officials from different levels of government disagree on who should be in charge of a situation
local governments have the most power, which creates problems for trade with other nations
officials from state governments have too many rules to follow to be effective leaders
Answer:
local governments have the most power
Step-by-step explanation:
I hope this is right, but federalism gives more power to the state, so local governments could potentially have more power.
Answer:
i believe it is option one: power and authority are concentrated in the central government and can take away people’s rights
Step-by-step explanation: well i mean its true the governments are corrupted and are slowly taking away our rights

there were 12 puppies but the number of puppies decreased by 25% when some were adopted. how many puppies remain?
Answer:
9 puppies
Step-by-step explanation:
12*0.75=9
75% remains
Answer:
9
Step-by-step explanation:
Number of puppies before adoption = 12
[tex]Number \ of \ puppies \ adopted = \dfrac{25}{100}*12 = \dfrac{1}{4}*12 = 3[/tex]
Number of puppies that remain = 12 - 3 = 9

Base Salary: $48,000
Applications: 910
Fee: $1.75 per application
what’s the total earning
Answer:
$49,592.50
Step-by-step explanation:
First, to find the total fee of application you times 910 by $1.75 which will give you
910 × 1.75 = 1592.5
Then you add 48,000 with 1,592.5
which will give you an answer of
48,000 + 1,592.5 = $49,592.50

S2x+3y=-12
(4x-4y=4
Answer:
I'll assume "S2x+3y=-12" is actually 2x+3y=-12 and that the question is to solve for x and y.
x = -(9/5)
y = -(14/5)
Step-by-step explanation:
2x+3y=-12
4x-4y=4
---
2x+3y=-12
8x+12y=-48 [Multiply the 1st equation by 4]
12x-12y=12 [Multiply the second equation by 3]
20x = -36 [Now we can add the two equations to remoce the y term]
x = -(36/20)
x = -(9/5) [The value for x]
====
2x+3y=-12 [Take either equation and s=use x=-(9/5) to find y]
2(-9/5)+3y=-12
-(18/5) + 3y = -12
+ 3y = -12 + (18/5)
y = -4 + (6/5)
y = -(20/5)+(6/5)
y = -(14/5) [This is the value of y that will work for both equations]
These equations both have the point (-9/5, -14/5) in common: they intersect here.
This problem can also be solved by graphing each equation and finding the point they inersect on the graph (attached).
