Question 46: A figure has a perimeter of 112 units. What will the new perimeter be after a dilation with a scale factor of 1/4?
Can someone please help me?
Answer: 65
Step-by-step explanation:
P = 2L + 2w <---- formula for perimeter
26 = 2L + 2w <--- original perimeter is 26
13 = L + w <--- divides everything by 2
32.5 = 2.5L + 2.5w <-- scale factor of 2.5; those are the NEW length and width
Multiplying both sides by 2, the new perimeter is 65;

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.

Work out the PED for each, and comment on your result. The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m. The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000. The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m Question 2
Answer:
a.) PED = 5
b.) PED = 5
c.) PED = 0.05
Step-by-step explanation:
Here , PED = Price elasticity of demand
a.)
Given - The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m.
PED = (Change in quantity demanded)×[tex]\frac{Initial Price}{Initial Quantity demanded}[/tex]
Now,
Change in quantity demanded = [tex]\frac{6 - 4}{180 - 200}[/tex] = [tex]\frac{2}{20} = \frac{1}{10}[/tex]
⇒PED = [tex]\frac{1}{10}[/tex]×[tex]\frac{200}{4}[/tex] = 5
b.)
Given -The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000.
Change in quantity demanded = [tex]\frac{1000000 - 950000}{1.10- 1}[/tex] = [tex]\frac{50000}{0.10} = 500000[/tex]
⇒PED = [tex]500000[/tex]×[tex]\frac{1}{1000000}[/tex] = 5
c.)
Given -The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m
Change in quantity demanded = [tex]\frac{2.2 - 2}{30 - 1.50}[/tex] = [tex]\frac{0.2}{28.50} = \frac{20}{2850} = \frac{2}{285}[/tex]
⇒PED = [tex]\frac{2}{285}[/tex]×[tex]\frac{1.50}{2}[/tex] = [tex]\frac{15}{2850}[/tex]= [tex]\frac{1}{190}[/tex] = 0.005

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

On a scale drawing, 1 centimeter represents 2 meters. What length on the drawing should be used to represent 3.2 meters?
Answer:
The answer to this problem is 36
Answer:
Your answer will be 1.6cm
Step-by-step explanation:
1cm represents => 2m
Or
2m is represented by 1 cm
then,
1m will be represented by => 1/2 cm [{unitary method}]
then,
3.2 m will be represented by
=> (1/2 × 3.2) cm [{unitary method}]
=> ( 3.2 / 2) cm
=> 1.6 cm
Therefore| : Ans will be 1.6 cm
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]

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).

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).

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.
