Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21
The given ratio of powder to water is 3:2 based on weight for Kool-aide. It is also given that 120g of flavored powder is needed for a certain amount of Kool-aide.
Let us assume that the amount of water (by weight) required to maintain the given ratio of 3:2 be represented by the letter 
. Thus, from the given information we can conclude that:
Cross-multiplying we get:
grams.
Thus, the amount of water in grams in that Kool-aide is 80 grams.
Answer:
16 bombons de coco
Step-by-step explanation:
A partir da pergunta, somos instruídos a fingir que o número total de bombons (chocolate) que ela fez = 24 bombons
Do total de chocolates que ele fez, 2/3 são de coco.
Portanto, a quantidade que representa os doces de coco é representada como:
2/3 × 24
= 16
Portanto, a quantidade de bombons de coco = 16
