Answer:
A: ∠W'Z'Y' = 60°; angles aren't changed by rotation
B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)
Step-by-step explanation:
Part A:
Angle WZY is the supplement of the given angle ZWX, so is ...
∠WZY = 180° -120° = 60°
Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...
∠W'Z'Y' = 60°
__
Part B:
The transformation right 2 and up 3 can be described by ...
(x, y) ⇒ (x +2, y +3)
Then the translated vertices are ...
W(-5, 3) ⇒ W'(-3, 6)
X(7, 3) ⇒ X'(9, 6)
Y(6, -2) ⇒ Y'(8, 1)
Z(-6, -2) ⇒ Z'(-4, 1)
Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.
Answer:
2.16
Step-by-step explanation:
r = cost of ruler
p = cost of pencil
r = 2p
6r + 15p = 2.16
Substitute 2p in place of r in 2nd equation and solve for p
6(2p) + 15p = 2.16
12p + 15p = 2.16
27p = 2.16
9y-7=29
Prove y=4
Solve the problem
9y - 7 = 29
=> 9y = 29 + 7 [Transferring 7 to R.H.S.]
=> 9y = 36
=> y = 36/9 [Transferring 9 to R.H.S.]
=> y = 4
Hence proved.

Answer:
x=55
Step-by-step explanation:
Since the two lines are parallel the two angles are same side exterior. This means their sum is 180. So to solve put them equal to 180, x+9+2x+6=180.
First, combine like terms
3x+15=180
Then, subtract 15 from both sides
3x=165
Finally, divide the entire equation by 3
x=55
write 8867 to 2 significant figures

The cost price of an electronic fan is Rs 2,800. If the shopkeeper marks its price
30% above the cost price and sells it at 10 % discount, how much should a
customer pay for it with 15 % VAT?
Answer:
cp=2800
mp=cp+30%of cp=2800+30/100×2800=3640
discount=10%
discount amount=10%ofmp=10/100×3640=364
sp=mp-discount=3640-364=3276
vat=15%
sp with vat=sp+vat%of sp=3276+15/100×3276=3276+491.4=3767.40
The price customers pay for it with 15 % VAT is Rs 3767.40 if the cost price of an electronic fan is Rs 2,800.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
The cost price of an electronic fan is Rs 2,800.
Cost with 30% above the cost price = Cost price +30% of cost price
= 2800 + (30×2800)/100
= 3640
Discount = 10%
Discount amount = 10% of 3640 = 364
Discounted price = 3640 - 364 = 3276
VAT = 15%
Discounted price with VAT = 3276 + 15% of 3276
= 3767.40
Thus, the price customers pay for it with 15 % VAT is Rs 3767.40 if the cost price of an electronic fan is Rs 2,800.

b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:

The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.
kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer:
Kyle's age = 18 years
Step-by-step explanation:
Let Megan's age = x
Kyle's age = 2x
Combined ages of Megan and Kyle = 27
x + 2x = 27
3x = 27 {Divide both sides by 3}
3x/3 = 27/3
x = 9
Megan's age = 9 years
Kyle's age = 2 * 9 = 18 years

Shawna was going to sell all of her stamp
collection to buy a video game. After selling half of them she changed her mind. She then bought five more. How many did she start with if she now has 30?
Answer:
She started with 50 stamps
Step-by-step explanation:
Hi! For these types of problems we always result to going backwards. So, she now has 30 right? So, to reverse into the problem, we do the opposite of what it says. "She then bought five more" 30 - 5 = 25. Then it says she sold half of them. 25 x 2 = 50. If we recheck by going back, she sold half of them (50 / 2 = 25) and she bought five more (25 + 5 = 30).
Hope this helps!

PLEASE HELP!?!?!?!?! In our amusement park that we built this week, the ride Diablo’s Domain had revenue of $250,000,000 in its first year as expected. The company paid $750,000 for insurance or $3 for every $1,000 in revenue. If the park is wildly successful and revenue increases by 25% in the second year and the rate of $3 for every $1,000 holds true, how much would it pay for insurance? Do you think it’s reasonable for insurance costs to increase proportionally? Why or why not?
Answer:
1) The amount to be paid as insurance if the revenue increases is $937,000
2) Yes because the total value of the risk insured and the likelihood of the occurrence of the risk both increases
Step-by-step explanation:
1) The given amount in revenue of the Diablo's Domain = $250,000,000
The amount the company paid as insurance = $750,000
The equivalent amount the company paid as insurance = $3 for every $1,000
The percentage amount in revenue the park revenue increases by = 25%
Therefore, the new amount in revenue = 1.25 × $250,000,000 = $312,500,000
The amount to be paid as insurance if the revenue increases = $315,500,000 × 3/1000 = $937,5000
The amount to be paid as insurance if the revenue increases = $937,000
2) It is reasonable for the insurance cost to increase proportionally when the items insured which leads to the increase in revenue increases because the value of the risk insured which is the event of settlement for losses increases as well as the probability of the risk occurring also increases.
Solve the system using substitution.
2x - 5y = 26
X - 5y = 3
Answer:
(x, y) = (23, 4)
Step-by-step explanation:
2x - 5y = 26
x - 5y = 3 $\Rightarrow$ x = 3+5y
substituting the value of x ( second equation) into the first equation, we get, 2(3+5y) - 5y = 26. Simplifing, we get,
6+10y - 5y =26
5y = 20
y = 4
So, x = 3+5*4 = 3+20 = 23
Answer:
[tex]\left \{ {{x=23} \atop {y=4}} \right.[/tex]
Step-by-step explanation:
[tex]\left \{ {{2x - 5y =26} \atop {x-5y=3}} \right.[/tex]
you can add 5y to both sides of the second equation:
[tex]x = 5y + 3[/tex]
Then, substitute:
[tex]2(5y + 3) - 5y = 26[/tex]
use the distributive property on the left side:
[tex]10y + 6 - 5y = 26[/tex]
[tex]5y + 6 = 26[/tex]
subtract 6 from both sides
[tex]5y = 20[/tex]
divide both sides by 5
[tex]y = 4[/tex]
Substitute into original equation
[tex]x - 5y = 3 --> x - 5(4) = 3\\x - 20 = 3\\x = 23[/tex]

To increase a liability, you will record it as
A. a credit
B. current
C. noncurrent
D. debit
Answer:
The answer is A.) a credit
Step-by-step explanation:
I hope this helps!
Answer:
If you ask a banker whether debiting or crediting a liability increases the account’s balance, the financier will tell you it depends on the transaction. The same answer holds true for accounting procedures, even though banking debits and credits are distinct from accounting practices. To understand the effects of journal entries on financial accounts, it’s important to master such terms as liability, record keeping and financial reporting.

Which table matches 4x+7y=19?
Answer:
c
Step-by-step explanation:
The table which matches 4x + 7y = 19 is table (d).
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Given is a linear equation,
4x + 7y = 19
(a) When x = -18,
7y = 19 - (4 × -18) = 91 ⇒ y = 13
When x = 1,
7y = 15 ⇒ y = 2.14
So the table (a) is not the one.
(b) When x = -9, 7y = 55, y = 7.857
Table (b) is also not the one.
(c) When x = 0, y = 2.7
Hence (c) is also not an option.
(d) When x = -18, y = 13
When x = -11, 7y = 63, y = 9
When x = -4, 7y = 35, y = 5
So the correct option is table (d).
Hence the correct option is table (d).
