Answer:
7 dollars
Step-by-step explanation:
To solve, use this equation:
34.20 - (16 x 1.70) = x
First do 16 x 1.70
This equals 27.2
34.20 - 27.2 = x
Now subtract
34.20 - 27.20 = $7
The student card $7
Answer:
There are 8 penguins and 6 reindeers.
Step-by-step explanation:
Since Brian, the gorilla, was planning a party for his zoo friends, and he sent his elves Jamie and Nancy into the North Pole exhibit to count the penguins and reindeer, and Jamie said there were 40 legs and Nancy said there were 14 heads To determine how many penguins and reindeer were in the exhibit, the following calculation must be performed:
Penguins: 1 head and 2 legs
Reindeers: 1 head and 4 legs
40 - (14 x 2) = X
40 - 28 = X
12 = X
12/2 = 6
14 - 6 = 8
8 x 2 + 6 x 4 = X
16 + 24 = X
40 = X
Therefore, there are 8 penguins and 6 reindeers.
If your referring to it when converted to inches, then 3.15 (3 15/100)
8 centimeters = 3.15 (3 15/100) inches
Your answers are? Please give the answers to this question. Then I may help
y = 70000(0.5)^(x/4), where x equals the number of hours.
(Attached is an image with the equation properly formatted.)
The function for exponential decay is <em>y = a(1 - b)^x</em>, where y is the final amount, a is the starting amount, b is the decay percentage in decimal form.
So, just fill in the values.
y = 70000(1 - 0.5)^x
y = 70000(0.5)^x
In this case however, x represents the number of sets of four hours, so we should probably divide x by 4 to make x represent the number of hours.
y = 70000(0.5)^(x-4)
