Answer:
(A)[tex]\angle A =\angle A.[/tex]
Step-by-step explanation:
[tex]\triangle AED \sim \triangle ACB$ by SAS and:\\\dfrac{AE}{AD} =\dfrac{AC}{AB}[/tex]
By the SAS Similarity Theorem, if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
The included angle between the sides AC and AD in AED is angle A.The included angle between the sides AC and AB in ACB is angle A.Therefore, for the two triangle to be similar by SAS, [tex]\angle A \cong \angle A.[/tex]

Weekly demand for cell phones at a Best Buy store is normally distributed, with a mean of 300 and a standard deviation of 200. The supplier takes two weeks to supply a Best Buy order. Best Buy is targeting a CSL of 95 percent and monitors its inventory continuously. How much safety inventory of cell Chopra, Sunil. Supply Chain Management (What's New in Operations Management) (p. 346). Pearson Education. Kindle Edition.
Answer:
The amount of safety inventory of cell phones best buy should carry is $465.277
Step-by-step explanation:
Solution
We recall that:
The weekly demand for cell phones= 300 per week
The Standard Deviation = 200 per week
The lead time or number of weeks = 2 weeks (14 days)
Thus,
Z = 95%
= 1.645
Now,
The standard deviation of lead time = Standard deviation√ *√ lead time
Which is
= 200 * √ (2) =2.82.843
So,
The safety inventory = Z * Standard deviation of the lead time
= 1.645 * 2.82.843
$465.277

Applying the cosine theorem for triangle ABC, you would have:
cos (angle BAC) = (BA^2 + CA^2 - BC^2)/(2*BA*CA)
= (10^2 + 18^2 - 20^2)/(2*10*18)
= 24/360
=> angle BAC = ~86 deg

Answer:
Step-by-step explanation:
The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices. The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices. Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select two options. For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices. For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line. The Hernandez family’s slices are smaller than the Wilson family’s slices. If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices. The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.

Which of the following is NOT a collinear point in the image below?
Laure
Lauren made a shopping list of things she could buy
with $100.
Answer:
The shoes and purse each take up 1/4th of the circle (since 25 is 1/4th of 100) so we can eliminate the top 2 choices. Since the dress costs more than the bracelet it will take up more room leaving us with the bottom right circle as the answer.
Answer: The fourth one, or the bottom right hand corner one
Step-by-step explanation:
Shoes: 25 --> 25%
Purse: 25 --> 25%
Bracelet: 15 --> 15%
Dress: 35 --> 35%
Since the circle graph are not exact percentages, you have to estimate on how which values are larger.
Please help !! Correct and first answer I will give you brainesttttt!!!!! What is the equation of the line ?
Answer:
y = 3x + 5
Have a good day! :)
Answer:
y=2x+4
Step-by-step explanation:
the line has equation like this y=ax+b
x=0 then y=4 so 4=a*0+b so b=4
y=0, then x=-2, 0=a*(-2)+4 so -2a+4=0,-2a=-4, a=2
so the equation of the line is y=2x+4
verify
x=-1, y=2*(-1)+4=-2+4=2 so the equation is correct
which equation is an identity?
Answer:
Option (3).
Step-by-step explanation:
Option (1).
3(x - 1) = x + 2(x + 1) + 1
3x - 3 = x + 2x + 2 + 1
3x - 3 = 3x + 3 [Not True]
Therefore, this equation is not an identity.
Option (2).
x - 4(x + 1) = -3(x + 1) + 1
x - 4x - 4 = -3x - 3 + 1
-3x - 4 = -3x - 2 [Not true]
Therefore, this equation is not an identity.
Option (3).
2x + 3 = [tex]\frac{1}{2}(4x + 2) + 2[/tex]
2x + 3 = 2x + 1 + 2
2x + 3 = 2x + 3 [True]
Therefore, this equation is an identity.
Option (4).
[tex]\frac{1}{2}(6x-3)=3(x+1)-x-2[/tex]
3x - 1.5 = 3x + 3 - x - 2
3x - 1.5 = 2x + 1 [Not true]
Therefore, this equation is not an identity.
Answer:
2x + 3 = 1/2(4x + 2) + 2

This year Tammy watched 60 movies. She thought that 15 of them were very good. Of the movie she watched, what percentage did she rate as very good?
Answer:
25%
Step-by-step explanation:
She watched in total 60 movies. Out of that total, she rated 15 of them as very good. Thus, she rated 15/60 or 1/4 or a quarter of them as very good.
To convert 1/4 into a percentage, simply divide them and you get 0.25. The percentage is the first two digits after the decimal, which is 25%.
"Find the surface area of the following shapes. Round to the nearest tenth if necessary." Is this correct? (Bold Mikado is my work.)
Answer:
360 cm^2
Step-by-step explanation:
First find the area of the bottom
10*10 = 100
The find the area of one of the triangular shapes
A = 1/2 bh since it is a triangle
A = 1/2 ( 10)*13 = 65
Since there are 4 triangles ( 1 for each side), multiply by 4
4*65 = 260
Add the areas together
260+100 = 360

Answer:
B. -2
Step-by-step explanation:
Solve x^2 + 4x + 8 = 0
Answer:
x = -2 + 2 i or x = -2 - 2 i
Step-by-step explanation:
Solve for x:
x^2 + 4 x + 8 = 0
Subtract 8 from both sides:
x^2 + 4 x = -8
Add 4 to both sides:
x^2 + 4 x + 4 = -4
Write the left hand side as a square:
(x + 2)^2 = -4
Take the square root of both sides:
x + 2 = 2 i or x + 2 = -2 i
Subtract 2 from both sides:
x = -2 + 2 i or x + 2 = -2 i
Subtract 2 from both sides:
Answer: x = -2 + 2 i or x = -2 - 2 i
The population of a city has increased by 35% since it was last measured. If the current population is 29,700 , what was the previous population?
Answer:
19305
Step-by-step explanation:
We simply take the percentage of 29700 to find how many people were added.
29700(0.35) = 10395 <== so 10395 people have been added
Subtract it from the current:
28700 - 10395 = 19305 people before.

Ping lives at the corner of 3rd Street and 6th Avenue. Ari lives at the corner of 21st Street and 18th Avenue. There is a gym 2/3 the distance from Ping's home to Ari's home. Where is the gym?
9th Street and 10th Avenue 12th Street and 12th Avenue 14th Street and 12th Avenue 15th Street and 14th AvenueAnswer:
(D)15th Street and 14th Avenue
Step-by-step explanation:
Ping's Location: (3rd Street, 6th Avenue)
Ari's Location: (21st Street, 18th Avenue)
The gym is at point P which is [tex]\dfrac{2}{3}[/tex] the distance from Ping's home to Ari's home.
That is, Point P divides the line segment in the ratio 2:1.
We use the section formula:
[tex](x,y)=\left(\dfrac{mx_2+nx_1}{m+n}, \dfrac{my_2+ny_1}{m+n}\right)[/tex]
m:n=2:1, [tex](x_1,y_1)=(3,6), (x_2,y_2)=(21,18)[/tex]
[tex]=\left(\dfrac{2*21+1*2}{2+1}, \dfrac{2*18+1*6}{2+1}\right)\\=\left(\dfrac{45}{3}, \dfrac{42}{3}\right)\\=(15,14)[/tex]
The gym is located at 15th Street and 14th Avenue.
If Rob had average monthly expenses of $940.21 and his expenses in April were $945.50 and his expenses in May were $875.13, what were his expenses in June?
Answer:
$1000
Step-by-step explanation:
If we assume that the given average applies to April, May, and June expenses, then we can use the formula for average to find June's expenses.
average expenses = (April +May +June)/3
940.21 = (945.50 +875.13 +June)/3
(3)(940.21) = 1820.63 +June
2820.63 -1820.63 = June = 1000.00
Rob's expenses in June were $1000.00.
Kenneth had $5. He spent g cents everyday. How much money he left afterone week? (a) Give you answer in cents (b) Give your answer in dollars.
Answer:
answer in cents = (500 - 7g ) cents
answer in dollars = ((500 - 7g)/100 ) dollar
Step-by-step explanation:
Money with Kenneth = $5
we know that 1 dollar = 100 cents
Money with Kenneth in cents= 5*100 = 500 cents
Money spent in 1 day = g cents
Money spent in 1 day in dollar = g /100 dollar
(a) Give you answer in cents
One week has 7 days
money spent in 7 days = Money spent in 1 day*7 = g*7 = 7g cents
Money left with Kenneth after one week= total money Kenneth had in cents - money spent in 7 days = (500 - 7g ) cents
(b) Give you answer in cents dollars
One week has 7 days
money spent in 7 days in dollars = Money spent in 1 day*7 = g/100*7 = 7g/100 cents
Money left with Kenneth after one week= total money Kenneth had in dollars - money spent in 7 days = (5 - 7g/100 ) dollar
= ((500 - 7g)/100 ) dollar
A test consists of 580 true or false questions. If the student guesses on each question, what is the standard deviation of the number of correct answers? Round the answer to the nearest hundredth.
Answer:
12.04
Step-by-step explanation:
Because the questions are true and false, that is, there are only two answer options, therefore, you have a success probability = 1/2 = 0.5
The standard deviation can be calculated as follows:
Standard Deviation = (n*p* (1-p)] ^ (1/2)
replacing we have:
SD = (290 * (1-0.5)] ^ (1/2) = 12.04
That is, the standard deviation is 12.04
A biker’s speed is 1.5 times faster than a walker’s. They started simultaneously from the same point and in 1.5 hours the distance between them was 12.5 miles. What are their speeds?
Answer:
Biker = 25 mph
Walker = 16⅔ mph
Step-by-step explanation:
Distance = rate × time
If x is the walker's speed and y is the biker's speed, then:
1.5 y − 1.5 x = 12.5
y = 1.5 x
Solve the system of equations.
1.5 y − y = 12.5
0.5 y = 12.5
y = 25
x = 16⅔
