Priscilla is drawing a map of her school that uses a scale in which 1.5 cm on the map represents 3 feet. If the first hallway has a length of 120 feet, what should the length of the hallway be on the map?
1 point
a. 40 cm
b. 60 cm
c. 30 cm
d. 45 cm
Answer: 60 cm
Step-by-step explanation: The conversion from 1.5 cm to 3 feet or 91.4 cm is 60.9 and 120 feet or 3657.6 cm divided by 60.9 is 60 cm so therefore the length of the hallway on the map should be 60 cm
Find the percent error in this situation:
Estimated value: 145
Actual value: 189
Answer:
30.3% im so sorry if this is wrong if it is u can report this :(
Step-by-step explanation:
Answer:
23.3%
Step-by-step explanation:
You have to first take the estimated value - the actual value
= 145-189 = -44
Then you want to take -44 divide the actual value which is 189
= -44 / 189= 0.232804233
Lastly, you want to take 0.232804233 and multiply it by 100
= 0.232804233 x 100= 23.28042328
Round that number to get
=23.3%

The volume of a cylinder whose radius is 2r cm and height h/4cm is______________
Answer:
V=πrh/2
Step-by-step explanation:
volume of a cylinder can be calculated using below formula
V=πr2h
Given:
radius =2r cm
height= h/4cm
If we substitute the given value into the formula we have πrh/2
V= π ×(2r) ×(h/4)
Simplyfying
V=πrh/2
Hence, The volume of a cylinder is V=πrh/2

Your client gets a bill from a French vendor for 100 euros on March 1 at an exchange rate of 1.2 dollars to the euro and pays on April 1 at an exchange rate of 1.3 dollars to the euro. What would you see in the Transaction Journal for the bill payment?
Answer:
The Transaction that to be entered in the Account would be:
Account payable A/c Dr. 130$
To Bank A/c 130$
Also,
Profit and Loss A/c Dr. 10$
To Foreign Exchange Fluctuation loss A/c 10$
Step-by-step explanation:
client received a bill as per question mentioned of 100 Euros on March 1 when the exchange rate is 1 Euro = 1.20 $,
Accordingly the price liable to be paid as on date 1 March is
100 Euro × 1.20= 120 $ .
Further, the client is agreed to pay the amount on the April 1 when the exchange rate stands out at 1.30 $, that specifies that the client now has to pay the extra price due to the exchange rate fluctuation i.e.
(1.30 - 1.20)$ = 0.10$ to the French vendor.
Therefore , the Transaction that to be entered in the Account would be:
Account payable A/c Dr. 130$
To Bank A/c 130$
Also,
Profit and Loss A/c Dr. 10$
To Foreign Exchange Fluctuation loss A/c 10$

What is the value of p?
Answer:
P = 18
Step-by-step explanation:
:) that the answer.
Answer:
Sum of the interior angles of the triangle is 180°.
According to the above problem,
[tex]4p + 4p + 36 = 180 \\ 8p = 180 - 36 \\ 8p = 144 \\ p = \frac{144}{8}\\ \boxed{p = 18}✓[/tex]
p=18° is the right answer.Malachy was thinking of a number. Malachy halves the number and gets an answer of 67.3.
Form an equation with x from the information.
Step-by-step explanation:
Let the number be x.
ATQ,
Malachy halves the number and gets an answer of 67.3.
[tex]\dfrac{x}{2}=67.3[/tex]
This the equation for the given statement.
It can also be written as :
[tex]x=2\times 67.3\\\\x=134.6[/tex]
Hence, this is the required solution.
