Answer:
u=2s
Step-by-step explanation:
just took the exam
The expression that most effectively represents u's value would be:
D). u = 2s
Given that,
In ΔABC,
E is the midpoint in the segment AC,
While D is the midpoint of BC,
As different letters are provided equivalent to different segments. For example; Segment ED = s ; Segment CE = p ; Segment EA = r
Segment CD = q ; Segment DB = t ; Segment ED = s ; Segment AB = u
As,
CE = 0.5 × AC(midpoint)
CD = 0.5 × CB (midpoint)
Thus,
CE/AC = CD/CB = ED/AB = 1/2 (Through side angle side similarity)
Since ED = s and AB = u
∵ u = 2s (using midpoint theorem)
Thus, option D is the correct answer.

Answer:
Store A
Step-by-step explanation:
Store A
50/100=0.5
0.5×5=2.5
The watch will be 50-2.5=47.5
Store B
60/100=0.6
0.6×20=12
The watch will be 60-12=48
So the watch price in store A is better
Answer:
You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.
Step-by-step explanation:
First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.
Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.
50 - 2.5 = 47.5
When you buy from Store A, you will pay $47.5
Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.
60 - 12 = 48
When you buy from Store B, you will pay $48
Ultimately, Store A is the best option because you're paying less.
What is the equation of the line in point-slope form?
Answer:
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the equation in point slope form
From the graph, we have the following points;
[tex](x_1,y_1) = (-400,-400)[/tex]
[tex](x_2,y_2) = (100,-500)[/tex]
First, we calculate the slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-500 - (-400)}{100- (-400)}[/tex]
[tex]m = \frac{-500 +400}{100+400}[/tex]
[tex]m = \frac{-100}{500}[/tex]
[tex]m = -\frac{1}{5}[/tex]
The equation is then calculated using:
[tex]y - y_2 = m(x - x_2)[/tex]
Substitute x and y values
[tex]y - (-500) = -\frac{1}{5}(x - (100))[/tex]
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]

Answer:
Reactants: aluminum and copper chloride.
Products: copper and aluminum chloride.
Step-by-step explanation:
Let's consider the following equation.
aluminum + copper chloride ⇒ copper + aluminum chloride
Using chemical symbols, this would be:
2 Al + 3 CuCl₂ ⇒ 3 Cu + 2 AlCl₃
The substances to the left of the arrow are the reactants: aluminum and copper chloride.
The substances to the right of the arrow are the products: copper and aluminum chloride.

A bag contains 120 marbles. Some are red and the rest are black. There are 17 red marbles for every 3 black marbles. How many red marbles are in the bag?
Given :
A bag contains 120 marbles. Some are red and the rest are black. There are 17 red marbles for every 3 black marbles.
To Find :
How many red marbles are in the bag.
Solution :
Let, number of red and black marbles are x and y respectively.
So, x + y = 120 ....1)
Now, it is given that there are 17 red marbles for every 3 black marbles.
So, 3x = 17y ....2)
Putting value of x from equation 2) to equation 1), we get :
[tex]\dfrac{17y}{3}+y = 120\\\\\dfrac{20y}{3}=120\\\\y = 18\\\\x = 120 - 18\\\\x = 102[/tex]
Therefore, the number of red and black marbles are 102 and 18 respectively.

What is the volume V of the sphere. Write the answer in terms of pie.
Plz help
Answer:
Volume=972π units cubed.
Step-by-step explanation:
The formula for the volume of a sphere is:
V=4/3πr^3
where r=radius
and v=volume
so we know the radius of the sphere in the diagram is 9 cm
so r=9 cm
we can subsitute this into the formula and solve.
V=4/3π(9^3)
V=4/3π*729
V=972π units cubed.
can you help me please
Answer:
Please check the explanation.
Step-by-step explanation:
Given that
|v|=38
Ф = 120°
Finding the horizontal component
The horizontal component can be obtained using the formula
Vx = |v| cos Ф
= 38 cos 120°
= 38 (-0.5)
= -19
Thus, the horizontal component is:
Vx = -19
Finding the vertical component
The vertical component can be obtained using the formula
Vy = |v| sin Ф
= 38 sin 120°
= 38 (0.86)
= 32.68
Thus, the vertical component is:
Vy = -19
A vector 'v' with magnitude |v| and direction Ф can be written as:v = |v| cos Ф i + |v| sin Ф j
As
|v|=38
Ф = 120°
Thus, the vector is
v = 38 cos 120° i + 38 sin 120° j
or
v = -19 i + 32.68 j

Triangle MNO is congruent to Triangle PQR. What is the measure of
Answe
Step-by-step explanation:
Answer: C :79.5
Step-by-step explanation:
Since both triangles are congruent the angles are also congruent. P the measure we are trying to find is congruent to M since they’re equal it should look like this
5x-19 = 3x+20.4
5x = 3x+ 39.4
2x = 39.4
X= 19.7
to find the measure of angle P plug in X to its equation so
3x + 20.4
3 (19.7) + 20.4
= 79.5

Help pls .. Determine if the two triangles are congruent. If they are , state how you know.
A. SAS
B. AAS
C. Not enough information
D.SSS
Answer:
C. not enough info
Step-by-step explanation:
Since the indicated angle in the triangle on the left is between the two sides that are marked congruent, and the marked angle on the triangle on the right is not between the two marked sides, there is not enough information to say whether the two triangles are congruent or not.

neither parallel nor perpendicular
Submit Answer
parallel
perpendicular
the same line
Answer:
they are not the same line, nor are they parallel or perpendicular
Step-by-step explanation:
they are two distinct lines and intersect at (-5.4, -0.4) if graphed
If you put each equation into slope-intercept form you can compare slopes to determine if they are parallel (slopes would be the same) or perpendicular (slopes would be opposite signs and reciprocals)
