Answer:
t = 480 seconds
Step-by-step explanation:
Let
Time taken for a water heater to boil water = t
power of the water heater = p
Constant of proportionality = k
t = k/p
240 = k/2000
Cross product
240 * 2000 = k
k = 480,000
Find the time it takes to boil water when the power is reduced to 1000 Watts.
t = k/p
= 480,000/1000
= 480
t = 480 seconds
t = 480 seconds when p = 1000 watts
A 64-ounce container of sports juice costs $6.50. A 48-ounce container of the same juice costs $4.25. Which juice container is the better buy.
Answer:
The juice container that is a better buy is the 48 ounce container because the price per ounce is lower.
Step-by-step explanation:
In order to determine the juice container that is the better buy, you have to find the one that has a lower cost per ounce by dividing the price of each juice container by the number of ounces it has:
64-ounce container: 6.50/64=0.10
48-ounce container: 4.25/48=0.08
According to this, the answer is that the juice container that is a better buy is the 48 ounce container because the price per ounce is lower.

Given:a²=36
a=✓36
a=6
a:b=2:7
6:b=2:7
can be written as
6/b=2/7
2b=6*7
b=6*7/2
b=21

The public the perimeter of the polygon is 24 in each side of the polygon is three inches long what is the name of the polygon
Answer:
Octagon
Step-by-step explanation:
A polygon refers to a two-dimensional closed shape consists of straight sides.
Perimeter of a polygon = 24 inches
Length of each side of the polygon = 3 inches
Number of sides of a polygon = Perimeter of a polygon ÷ Length of each side of the polygon = [tex]\frac{24}{3} =8[/tex]
An octagon is a polygon consisting of 8 sides of same dimension.
So,
Name of polygon is octagon.

La suma de las edades de los hermanos Carlos y Felipe es igual a la edad de su tía María; Si María tiene 29 años y Carlos tiene 13 años, ¿Cuántos años tiene Felipe?
Answer:
16 años
Step-by-step explanation:
Si la suma de la edad de Carlos y Felipe es igual a la de Maria, y en la pregunta nos dan la edad de Maria (M) y Carlos (C), entonces tenemos que encontrar la edad de Felipe. Para calcular esto necesitamos restar la edad de Carlos de la edad de Maria. Esto nos dara la edad exacta de Felipe (f).
M - C = f
29 - 13 = f
16 = f
Finalmente, vemos que la edad de Felipe es de 16 años
