A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15 green counters in the bag. How many black counters are in the bag ?
Answer:
There are 5 black counters in the bag.
Step-by-step explanation:
15 green counters in the bag
The proportion of green counters is given by:
[tex]p = 1 - (\frac{1}{3} + \frac{1}{6}) = 1 - (\frac{2}{6}+\frac{1}{6}) = 1 - \frac{3}{6} = 1 - \frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}[/tex]
So, we have that, the total is x. So
[tex]\frac{x}{2} = 15[/tex]
[tex]x = 30[/tex]
There are 30 total counters.
How many black counters are in the bag ?
A sixth of the counters are black. So
[tex]\frac{1}{6} \times 30 = \frac{30}{6} = 5[/tex]
There are 5 black counters in the bag.

Adam earns $36 for every four hours of work. If he continues to be paid at the same rate:
a. How long will it take him to earn $144? Show and explain your reasoning.
b. How long will it take him to earn $222? Show and explain your reasoning.
c. How could you describe his rate for a 40-hour work week? For a 7-hour day? Show and explain your reasoning.
Answer:
a certain number that i do not know
Step-by-step explanation:
a). It will take 16 hours to earn $144.
b). It will take 24.67 hours to earn $222
c). In a 40 hours week he will earn $360.
In a 7 hours day he will earn $63.
Proportionality if two variables: If two variables 'x' and 'y' represent number of hours worked and total earning respectively,
Proportionality law states,
y ∝ x
y = kx [here, k = proportionality constant]
If Adam earns $36 in 4 hours,
36 = 4k
k = 9
Therefore, expression for total earnings will be,
y = 9x
a). For y = $144,
144 = 9x
x = 16 hours
b). For y = $222,
222 = 9x
x = 24.67 hours
c). For 40 hour week,
y = 9(40) = $360
Adam will earn $360 in a week by the rate $9 per hour.
For 7 hour day,
y = 9(7) = $63
Adam will earn $63 in a day by the rate of $9 per hour.
Therefore, a). It will take 16 hours to earn $144.
b). It will take 24.67 hours to earn $222.
c). In a 40 hours week he will earn $360.
In a 7 hours day he will earn $63.

An appliance store decreases the price of a 19-in. television set 23% to a sale price of $497.42. What was the original pric
Answer:
Original price was $2163
Step-by-step explanation:
Let original price be x
23% of x = 497.42
23/100 × x = 497.42
23x/100=497.42/1
Cross multipy,
23x × 1 = 497.42 × 100
23x=49742
x=49742/23
x=2,163 approximately
