ABC is an isosceles triangle.
• AB = AC = 11 cm
E
. E and F are the midpoints of AB
and AC respectively,
• EF is parallel to BC.
55
B
Find the area of the trapezium BEFC.
Answers
Answer: 90,75. cos 55°. sin55° ≈ 42,64
through E, draw EK perpendicular to BC (F ∈ BC)
because E is the midpoint of AB => BE = 11/2 = 5.5
ΔBEF is a right triangle at K
=> sin 55° = EK/BE
=> EK = 5,5.sin 55°
ΔABC has E and F is the midpoints of AB and AC
=> EF is the median line of the triangle
=> EF = 1/2.BC
through A, draw AD perpendicular to BC
=> ΔABD is a right triangle at D
=> BC = 11.cos 55°.2 = 22.cos 55°
=> EF = 11.cos 55°
=>the area of the trapezium BEFC is:
[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

Step-by-step explanation:
After cleaning house, Josh took a box of 29 used discs to sell at the flea market.
Some were computer games (which he sold for $2 each), some were music CDs (which he sold
for $3 each), and the rest were video DVDs (which he sold for $4 each). If Josh sold everything
(which included twice as many DVDs as computer games), and he made a total of $93, how
many of each type of disc did he sell?
Answers
Answer:
Josh sold, 6 computer games, 12 video DVDs, and 11 music CDs
Step-by-step explanation:
The given parameters are;
The number of used discs in the box Josh took to the flea market = 29
The price for which he sold the computer games = $2
The price for which he sold the music CDs = $3
The price for which he sold the video DVDs = $4
The number of DVDs = 2 × The number of computer games
The total amount Josh made = $93
Let C represent the number of computer games and let M represent the number of music CDs, and let V represent the number of DVDs, we have;
We have;
V = 2 × C...(1)
C + M + V = 29...(2)
2 × C + 3 × M + 4 × V = 93...(3)
By substituting the value of V, from equation (1), in equation (2), we have ;
C + M + (2 × C) = 29
∴ 3·C + M = 29
M = 29 - 3·C...(4)
By substituting the value of V, from equation (1) and the value of M, from equation (4) in equation (3), we have;
2 × C + 3 × M + 4 × V = 93...(3)
2·C + 3·M + 4·V = 93
2·C + 3·(29 - 3·C) + 4·(2·C) = 93
2·C + 87 - 9·C + 8·C = 93
C = 93 - 87 = 6
C = 6
The number of computer games = C = 6
V = 2 × C = 2 × 6 = 12
V = 12
The number of video DVDs = V = 12
M = 29 - 3·C = 29 - 3 × 6 = 11
M = 11
The number of music CDs = M = 11
Therefore, Josh sold, 6 computer games, 12 video DVDs, and 11 music CDs.

Three baseball players are playing catch. Herman is 6 meters south of Luca and 8 meters west of valentina. How far does Luca need to throw the ball to get it to Valentina
Answers
Answer:
Luca needs to throw the ball 10 meters to get to Valentina.
Step-by-step explanation:
Distance Between two Points in the Plane
Let's assume Luca is at the origin of coordinates (0,0).
Since Herman is 6 meters south of Luca, he is located at (0,-8).
We also know Herman is 8 meters west of Valentina, or equivalently, Valentina is 8 meters east of Herman. This locates Valentina at (6,-8).
If Luca wanted to throw the ball to Valentina, he would need to cover the distance between them.
Thus the problem reduces to find the distance between (0,0) and (6,-8).
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
Applying the formula:
[tex]d=\sqrt{(-8-0)^2+(6-0)^2}[/tex]
[tex]d=\sqrt{(-8)^2+(6)^2}[/tex]
[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]
d=10 m
Luca needs to throw the ball 10 meters to get to Valentina.

A person receives a paycheck of d dollars. The person spends 18% of the
paycheck on rent, 15% of the paycheck on insurance, and 22% of the paycheck
on food and puts the remainder of the paycheck into savings.
If the amount the person puts into savings can be
represented by the
expression d - 0.18d - 0.15d - 0.22d, which expression also represents the
amount the person puts into savings?
O 0.45d
O 0.550
O 1.450
O 1.550
Answers
Answer:
0.45d
Step-by-step explanation:
Given that :
Amount of paycheck = d
Amount spent on rent = 18%
Amount spent on insurance = 15%
Amount spent on food = 22%
Amount put into savings = d - 0.18d - 0.15d - 0.22d
Amount put into savings = d - ( 0.18d + 0.15d + 0.22d)
d - 0.55d
Amount put into savings = 0.45d

Step-by-step explanation:
We would have to subtract the total cost to the cost that is $3.50 more than the other
We do $17.00 - $3.50, would give us $13.50,
We divide the answer by two as O'Brian bought two magazine,
this will leave us with the answer 13.50/2 = 6.75

Blue Skies Equipment Company uses the aging approach to estimate bad debt expense at the end of each accounting year. Credit sales occur frequently on terms n/60. The balance of each account receivable is aged on the basis of three time periods as follows: (1) not yet due, (2) up to one year past due, and (3) more than one year past due. Experience has shown that for each age group, the average loss rate on the amount of the receivable at year-end due to uncollectibility is (a) 3 percent, (b) 9 percent, and (c) 28 percent, respectively. At December 31, 2019 (end of the current accounting year), the Accounts Receivable balance was $48,700 and the Allowance for Doubtful Accounts balance was $920 (credit). In determining which accounts have been paid, the company applies collections to the oldest sales first. To simplify, only five customer accounts are used; the details of each on December 31, 2019, follow:
Answers
Answer:
hello your question is incomplete attached below is the missing table
answer = $48700
Step-by-step explanation:
Calculate the total account receivable in each age category
1) not yet due age category
= $4000 + $4000 + $7000
= $15000
2) up to 1 year age category
= $20500 + $7000
= $27500
3) more than 1 year age category
= $6200
therefore the total amount of account receivables = 15000 + 27500 + 6200 = $48700

What is the slope of the line represented by the equation y
Answers
Step-by-step explanation:
y = -2/3 - 5x
rearranging,
y = -5x -2/3
comparing to the gradient-intercept equation
y = mx + c
m = -5
c = -2/3
Therefore, the slope of the line is -5
Answer: -5
Step-by-step explanation:
Because you know that y=Mx+p right?
So you just take the equation : -2/3-5x and you know that the number before x is m = the slope . Have a nice rest of your day :)

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.
What is the total amount Ellen will pay for the book?
Answers
Answer:
Ellen will pay $16.22 for the book.
Step-by-step explanation:
Part 1:
We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.
18 x 0.15 = $2.70
This lets us know that there is a $2.70 discount.
Now, let's subtract the discount from the regular price.
18 - 2.70 = $15.30
So, now we know the discounted price is $15.30
Part 2:
We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.
15.30 x 1.06 = $16.22 when rounded to the nearest cent.
Therefore, Ellen will pay the total amount of $16.22.
Answer:
$16.22
Step-by-step explanation:
marked price = $18 = 100%
discount = $? = 15%
selling price/ = $? = 85%
discounted price- this price is lower than the marked price as they have given you a DISCOUNT- an amount of money DEDUCTED.(a.k.a selling price)
selling price = 85% x $18 = $15.3= discounted price
100%
sales tax=6%
= 6 x 15.3 = 0.918 = $0.92=sales tax
100
total amount = discounted price + sales tax
= 15.3 + 0.92
= $16.22
Type SSS, SAS, ASA, SAA, or HL to
justify why the two larger triangles are
congruent.
Answers
Explanation: The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.
And in your triangles the hypotenuse legs are congruent (the hypotenuse is the largest side of the triangle) and the other part that is congruent is the middle leg because they are sharing that leg.
Hope this explanation helps you :D
The theorem that justifies why the two larger triangles are congruent to each other is: Hypotenuse-leg Congruence Theorem (HL).
What is the Hypotenuse-Leg Congruence Theorem?The Hypotenuse-leg Congruence Theorem (HL) states that if one leg and hypotenuse of a right triangle are congruent to one corresponding leg and hypotenuse of another, both right triangles are congruent.
