On a map, every 0.5 cm represents 25 km. If. London is 454 km away from Paris, about how far apart from each other do the cities appear on the map?
Answer: pretty sure it's c: 908cm
Step-by-step explanation:
454÷25= 18.16 and 18.16÷0.5= 908
Here we need to perform a change of units, from real distances to distances in a map.
We will find that the distance on the map is 9.08cm
Let's see how to get that.
First, the information that we have is:
Each 0.5 cm in the map represent 25 kmLondon is 454 km away from Paris.The first thing we need to find is how many times we have 25km in 454km, we will get:
n = 454km/25km = 18.16
Each one of these 18.16, is represented with 0.5cm in the map, then the distance in the map is:
distance = 18.16*0.5 cm = 9.08cm
The distance on the map is 9.08cm

Kevin gave 5/12 of his candy bar to Emily and 1/2 of his candy bar to David. How much of the candy bar does Kevin have left for himself? Your answer should be in the form of a simplified fraction. *
Answer:
[tex]Fraction\ Left = \frac{1}{12}[/tex]
Step-by-step explanation:
Given
[tex]Emily = \frac{5}{12}[/tex]
[tex]David = \frac{1}{2}[/tex]
Required
Determine the fraction left
The whole candy will be represented with 1:
So:
[tex]Emily + David + Fraction\ Left = 1[/tex]
This gives:
[tex]\frac{5}{12} + \frac{1}{2} + Fraction\ Left = 1[/tex]
Collect Like Terms
[tex]Fraction\ Left = 1 -\frac{5}{12} - \frac{1}{2}[/tex]
Take LCM
[tex]Fraction\ Left = \frac{12 - 5 - 6}{12}[/tex]
[tex]Fraction\ Left = \frac{1}{12}[/tex]
Hence, the fraction left is 1/12

Thang decided to borrow $6000 from his local bank to help pay for a car. His loan was for 3 years at a simple interest rate of 9
%. How much interest will Thang pay?
Answer:
Thang will pay $1620 interest
Step-by-step explanation:
Simple Interest
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Thang borrowed P=$6000 from his local bank. The loan was for t=3 years at a simple interest rate of r=9% = 0.09. The interest is calculated as:
I = 6000*0.09*3
I = 1620
Thang will pay $1620 interest
Si cada kilowatt por hora (kW.H) vale $ 0.95. ¿cuál será al cabo de un mes el costo debido a un bombillo de 100 W que permanece encendido 10 horas diarias?
Answer:
Un bombillo de 100 W consume 100W por hora.
Sabemos que el bombillo esta encendido 10 horas diarias, entonces en un día consume:
10*100 W = 1000 W = 1 kW.
En un día, hay 24 horas, entonces el consumo por hora (diario) es:
C = 1kW/24h = 0.042 kW/h.
El costo por kW/h es $0.95, entonces el costo diario es:
N = $0.95*0.042 = $0.0399
Y un mes tiene, en promedio, 30 días, entonces el costo mensual de este bombillo va a ser 30 veces el coste diario:
Costo mensual = 30*$0.0399 = $1.197

Sheila is trying to run a certain number of miles by the end of the month. If Sheila is 20% of the way to achieving her goal and she has already run 4 miles, how many miles is she trying to run by the end of the month?
Answer:
I think its 20 miles after the whole month
Step-by-step explanation:
20%=4
40%=8
60%=12
80%=16
100%=20
Sheila is trying to run 20 miles by the end of the month
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Sheila is trying to run a certain number of miles by the end of the month and she is 20% of the way to achieving her goal which is 4 miles.
Assuming she is trying to run x miles.
So, 20% of x miles is 4 miles.
∴ (20/100)×x = 4.
0.2x = 4.
x = 4/0.2.
x = 20 miles.

A half-circle is joined to an equilateral triangle with side lengths of 12 units. What is the perimeter of the resulting shape? Write your answer as a decimal rounded to the nearest tenth. Do not include the label.
Answer:
P = 42.84 cm
Step-by-step explanation:
A half-circle is joined to an equilateral triangle with side lengths of 12 units.
We need to find the perimeter of the resulting shape.
The perimeter of the half cirle is πr.
The diameter of the circle is 12. It means radius is 6 units.
An equilateral triangle has 3 equal sides. So, perimeter of the triangle is given by :
P = πr + 12 +12
= 3.14(6) + 24
= 42.84 cm
Hence, the perimeter of the resulting shape is 42.84 cm.
