Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is
Subtracting a negative means to add, so we have
Answer:Desmond will play for 10800 seconds in 6 days
Step-by-step explanation:
In a Day Desmond plays soccer = 30 minutes
In 6 days, he will play = 6 x 30 = 180 minutes
Changing 180 minutes to seconds
we know that 60 second s= 1 minutes
Therefore ?? seconds = 180 minutes
180 x 60 =10800 seconds
Answer:
A. 25 girls
Step-by-step explanation:
Suppose the number of boys is b and the number of girls is g.
We know that the ratio of boys to girls is 6 to 5, so we can write this as:
b:g = 6:5 or b/g = 6/5
We also know that there are 30 boys, so b = 30. We plug this value of 30 in for b in our ratio. Now, we just have a proportion with one variable g:
⇒ 
Cross-multiplying, we get:
6 * g = 30 * 5 = 150
g = 150/6 = 25
Thus, there are 25 girls, so the answer is A.
Hope this helps!
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
<h3>How to find a constant of proportionality in direct proportional equation</h3>
Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of <em>direct</em> proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:
k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
