Given that AD is the perpendicular bisector of BC, AB=21.3, AC=21.3, and DC=9.1, identify BC.
a) BC = 42.6
b) BC = 18.2
c) BC = 9.1
d) BC = 4.55
sorry i can't upload a picture of the triangle but this is from an luoa assignment. i know it's not C
answer. B hope this helps
The length of BC is 18.2 units.
The correct answer is option b) BC = 18.2.
Since AD is the perpendicular bisector of BC, it divides BC into two equal segments. Let's call the point of intersection between AD and BC as M. Therefore, BM = MC.
According to the given information,
AB = AC = 21.3. Since AD is the perpendicular bisector of BC, it implies that AM is equal to MC.
Therefore, AM = MC = BC/2.
We are also given that DC = 9.1. Since MC = DC, we can conclude that BC/2 = 9.1.
To find BC, we can multiply both sides of the equation by 2:
BC = 2 x 9.1
BC = 18.2.

What is the slope intercept equation for thus line?
Answer:
y= 2/3 x + 4
y- intercept= (0,4)
and slope of the line is 2/3
Answer:
B.
Step-by-step explanation:
y = mx + b
The y-intercept is the point (0, 4), so you get b = 4
You now have
y = mx + 4
Now start at the y-intercept, (0, 4). Go up 2 units and right 3 units to a point on the line; rise = 2; run = 2.
slope = m = rise/run = 2/3
Now you have
y = 2/3 x + 4
Answer: B.
3
What is the slope of the line y = 3x--?
4
so this equation is in y = mx + b form or slope intercept form
you can see that the slope is 3x since mx is slope
remember! m is always slope!

3.9 works so i would take the dot/period and bring it between 3 and 9, the dot would travel 10 places therefore you raise the 10 to the 10th power
3.9×10^10
4) and since 10 is raised to the 4th power you would just move the dot 4 places right and you get

9 men working in a factory produce a. certain number of pans in 6 working days. how long will it take 12 men to produce the same number of pans if they work at the same rate?
Answer:
It would take 12 men 4.5 (four and a half) days to do the same amount of work as the 9 men in 6 days.
Step-by-step explanation:
9 is 75% of 12 (12*.75=9) if they work at the same rate it would take 75% of the time it did for the 9 men (6hrs*.75=4.5)

also please make sure it isnt a decimal
Answer:
Actual answer would be 77.75 but you would answer as 78 I believe.
Step-by-step explanation:
Since they're over the same denominator this means that 4n= 311.
311/4=n
n=77.75
Or for you it would be 78 rounded up.
Or for a fraction it would be 77 1/4.

how to find the value of x in a triangle (5x-11)°, (2x+20)°, (11x-63)°
Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.

Cases sold: 3 6
Time (min): 20 40
a) They sell 27 cases in 3 hours
b) They sell 12 cases in 1 hr 20 minutes
c) They sell 18 cases in 2 hours
d) They sell 24 cases in 2 hrs 40 minutes
e) They sell 36 cases in 3 hrs 20 minutes
Answer:
1. $18.90
2. Every statement is true EXCEPT e
Step-by-step explanation:
For number 1. We first need to find how much one ticket costs. To find this we divide profit by number of tickets sold. So,
13.50/15 = $0.90
So to find the cost of 21 tickets we times the cost per ticket by 21
21 x 0.90 = 18.9
So $18.90
2.
They sold 6 cases in 40 minutes.
6/40 = 0.15
They sell 0.15 cases per minute
For a we wanna see if they can sell 27 cases in 180 minutes so
0.15 x 180 = 27
So a is true
B)
0.15 x 80 = 12
So b is true
C)
0.15 x 120 = 18
C is true
D)
0.15 x 160 = 24
D is true
E)
0.15 x 200 = 30
E is false
Evaluate each value expression for the given value of x: 2x+10, x=7
Answer: 24
Step-by-step explanation: Here, we have the expression 2x + 10,
and we want to evaluate the expression when x = 7.
To an evaluate an expression, we simply plug
the value of the variable into the expression, and solve.
So here, since x = 7, we have 2(7) + 10.
2(7) is equal to 14 so we have 14 + 10 which is equal to 24.
So the value of our expression when x = 7 is 24.

What is zero of a function?Zero of a function is defined as the roots of the function for which the value of the function will be 0 at those points.
If p is the zero of the function f(x)=0 then f(p)=0.
We have,
f(x) = (x-1)² (x+3)³ (x+1)
Now,
The zero is located at x=1 and has a multiplicity of 2.
Because the number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity.
The zero is located at x = - 3 and has a multiplicity of 3. The graph of the function will touch, but not cross, the x-axis at the x - the value of 1.
The complete question is given below:-
Consider polynomial function f f(x)=(x-1)^2(x+3)^3(x+1)

The cost of catering a dinner is $11.95 per person plus $25 for delivery and setup. Which statement is true about the graph of the function that represents the average cost per person?
The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases
the horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
The vertical asymptote x = 0 represents that the cost per person approaches $0 as the number of people increases
The vertical asymptote x = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
Answer:
Option "B" is the correct answer to the following question.
Step-by-step explanation:
The horizontal asymptote y = 11.95 reflects a cost each person reaching $11.95 because as number of individuals rises.
Horizontal asymptotic y = $11.95
Cost per person approaches = $11.95 per person increase
Answer:
B) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.

Task: You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay your friend 50 cents, but when a different number is rolled, your friend pays you 10 cents. After 30 rolls, it turned out that you were even, and neither of you won anything.
Answer:
u both got rickrolled
Step-by-step explanation:
\_( XD)_/
Answer:
6 times
Step-by-step explanation:
'one' 50 cents, other 10 cents
If you get 50 cents you have to roll other number 5 times to minus 50 cents (50 divided by 10 is 5)
because they got nothing after roll so if they get a cents they have to minus it rolling other number
So if you divide 30 (the number of rolling) by 5 (the number of times to minus 50 cents) so the answer will be 6

Which two changes are caused by shear acting on Earth's crust?

Step-by-step explanation:
The two changes caused by the shear on the earth crust are; A: One slab of rock breaks into two peices. C: Two slabs of rock slide past one another;
How to describe the shear acting on Earth's Crust?
Shear stress usually occurs when two plates rub against each other as they move in opposite directions.
Now, when shear stress occurs on the earth's crust, the force generated by the stress tends to push some of the crust in different directions. This would mean that a large part of the crust can break off, which makes the plate size smaller.
Thus, when a shear stress acts on the earths' crust, One slab of rock breaks into two peices. C: Two slabs of rock slide past one another;
