PLZ HELP ASAP 20 POINTS PLZ ANSWER THIS HOUR IF AC = 26 cm, what is BC?
20 cm
24 cm
26 cm
2√194cm
Answers
AB = BD = 10cm
Now using the Pythagorean theorem:
26^2 = 10^2 + BC^2
Simplify:
676 = 100 + BC^2
Subtract 100 from both sides:
576 = BC^2
Take the square root of both sides:
BC - sqrt(576)
BC = 24 cm

What’s the area? Please help!!
Answers
The area of the triangle can be found by A = 1/2bh
So the area will be 1/2 times (6+14+6= 26) 26 times 21
The area of the triangle will be 273 ft^2
The area of the square will be A=lxh
So the area will be 14 times 14
So the area of the square will be 196 ft ^2
We then add the area of both shapes together to get the total area
273 + 196 = 469 ft^2
9514 1404 393
Answer:
469 square yards
Step-by-step explanation:
The area of the triangle is ...
A = 1/2bh
A = 1/2(6+14+6)(21) = 273
The area of the square is ...
A = s^2 = 14^2 = 196
The total area of the figure is the sum of the parts.
273 +196 = 469 . . . square yards

During the two hours of the morning rush from 8 a.m. to 10 a.m., 80 customers per hour arrive at the coffee shop. The coffee shop has a capacity of 60 customers per hour. On average how long does a customer arriving during the morning rush wait to be served
Answers
Answer:
The average waiting time is 1/3 hours (or 20 minutes)
Step-by-step explanation:
Given
[tex]T = 2hours[/tex] --- Time
[tex]D = 80\ customers/hr[/tex] --- Arrivals
[tex]C = 60\ customers/hr[/tex] --- Capacity
Required
Determine the average waiting time
The average waiting time (AT) is calculated using the following formula:
[tex]AT = \frac{1}{2} * T * (\frac{D}{C} - 1)[/tex]
This gives:
[tex]AT = \frac{1}{2} * 2 * (\frac{80}{60} - 1)[/tex]
[tex]AT = 1*(\frac{80}{60} - 1)[/tex]
[tex]AT = (\frac{80}{60} - 1)[/tex]
Remove bracket
[tex]AT = \frac{80}{60} - 1[/tex]
Take LCM
[tex]AT = \frac{80-60}{60}[/tex]
[tex]AT = \frac{20}{60}[/tex]
[tex]AT = \frac{1}{3} hr[/tex]
or
[tex]AT = \frac{1}{3} * 60\ mins[/tex]
[tex]AT = 20\ mins[/tex]
A candy shop puts together two prepackaged assortments to be given to trick-or-treaters on Halloween. The feasible set for producing x packages of assortment A and y packages of assortment B has been graphed to the right. For the earnings function Earningsxy, where Earnings is in cents, how many of each assortment should be prepared in order to maximize profits? What is the maximum profit? 0 600 0 600 x y A coordinate system has a horizontal x-axis labeled from 0 to 600 in increments of 120 and a vertical y-axis labeled from 0 to 600 in increments of 120. A four-sided polygon labeled as the feasible set is formed by a series of line segments and their intersection with the x-axis and y-axis. The line segments are labeled as follows: y equals negative 2 x plus 600; y equals negative x plus 350. The shop should prepare nothing packages of assortment A and nothing packages of assortment B to maximize profit. (Type whole numbers.) The maximum profit is $ nothing. (Round to the nearest cent as needed.)
Answers
Answer:
Step-by-step explanation:
The correct question is attached in the image below;
From there, given that: the earnings = 60x + 50 y ------ (1)
y = -x + 175
for x = 0 ⇒ y = 175 ; Then Point A (0, 175)
y = -2x + 300
for y = 0 ⇒ x = 150 ; Then Point C (150, 0)
For Point B;
y = -x + 175 ---- (a)
y = -2x + 300 ---- (b)
Equating both (a) and (b) from above together; then:
⇒ -x + 175 = -2x + 300
⇒ x = 125
∴
From y = -x + 175
y = -125 + 175
y = 50
So point B ( 125, 50)
Now, the points are O(0, 0), A(0, 175), B(125, 50), C(150, 0)
As such, profit at these points are:
O(0, 0), Profit = 60 × 0 + 50 × 0 = 0
A(0, 175), Profit = 60 × 0 + 50 × 175 = 8750
B(125, 5), Profit = 60 × 125 + 50 × 50 = 10,000
C(150, 0), Profit = 60 × 150 + 50 × 0 = 9000
Hence, maximum profit takes place at B(125, 50) which is = $10,000
Finally, we can conclude that the shop should prepare 125 packages of assortment A and 50 packages of assortment B to maximize profit.
The maximum profit is $10,000

100 POINTS!!! Orthographic projection and isometric projection are two ways to show three-dimensional objects in a two-dimensional space, such as on a piece of paper or a computer screen. Each method gives a different perspective. Do some research and then compare and contrast the two methods for displaying three-dimensional shapes. Then try your hand at creating both types of projections for a simple geometric shape using paper, pencil, and a ruler.
In your opinion, what are the pros and cons of each projection? What are the limitations? In which circumstances, environments, or occupations is one type of projection likely preferred over the other? Describe any special tools that might be needed to create the projection. Which projection is easiest for you to interpret visually? Why?
Answers
Example 1:
The pros of Orthographic is that they can show hidden details and all of the connecting parts, they can be annotated to display material and finishes. The pros of Isometric projection is that they dont need many views and it gives accuracy, cons are is created a unorginized apperance by the lack of foreshortening, I would choose Isometric projection because it shows the size of the figure.
Example 2:
Orthographic projection is a good option for showing lots of detail and small things. The limitation is that with all of that detail, they can become quite messy and hard to understand to someone new to them. However, that is one of the pros of Isometric projection. It gives easy detail and is just as good as an Orthographic. Personally, I find Isometric projections easier to interpret.

The remaining piece of the board when [tex]3\frac{3}{8}[/tex] feet is cut off from the end of the board of [tex]6\frac{1}{2}[/tex] feet is
[tex]3\frac{1}{8}[/tex] feet
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example:
1/2, 1/3 is a fraction.
1/2 of 4 is 2.
1/4 of 20 is 5.
We have,
Length of the board = [tex]6\frac{1}{2}[/tex] feet.
The length cut off from the board = [tex]3\frac{3}{8}[/tex] feet.
The remaining length of the board:
= [tex]6\frac{1}{2}[/tex] - [tex]3\frac{3}{8}[/tex]
= 13/2 - 27/8
Find the Lcm of 2 and 8.
The Lcm of 2 and 8 is 8.
= (13x4 - 27) / 8
= (52 - 27) / 8
= 25/8
Write it in a mixed fraction.
= [tex]3\frac{1}{8}[/tex] feet
Thus,
The remaining piece of the board when [tex]3\frac{3}{8}[/tex] feet is cut off from the end of the board of [tex]6\frac{1}{2}[/tex] feet is [tex]3\frac{1}{8}[/tex] feet.

The Binomial Expansion of [tex](x+ 1)^6[/tex] is [tex]x^6[/tex] + 6[tex]x^5[/tex]y + 15[tex]x^4[/tex]y² + 20x³y³ + 15x²[tex]y^4[/tex] + 6x[tex]y^5[/tex] + [tex]y^6[/tex].
What is Binomial Expansion?An expression that has been raised to any finite power can be expanded using the binomial theorem. A useful expansion technique with applications in probability, probability theory, and algebra is the binomial theorem. A binomial expression is an algebraic expression with two terms that are not the same.
