Answer:
The speed of the boat in still water is 10 miles / hour
Step-by-step explanation:
The trip there, and the trip back are the same -- 30 miles
Let the rate of the boat = x
Let the rate of the water = y
30 = 2*(x + y)
30 = 6*(x - y)
Divide the top equation by 2
Divide the bottom equation by 6
15 = x + y
<u>5 = x - y </u> Add the equations together.
20 = 2x Divide by 2
20/2 = x
x = 10
Answer:
Total ways = 5×5×5×5×5
Total ways = 5^5
Total ways = 3125
Therefore, the correct option is C) 5^5
Step-by-step explanation:
John has pairs of red, orange, yellow, blue and green socks.
Which means that John has 5 different colors pairs of socks.
We are asked to find out in how many ways can he wear them over 5 days.
1st Day:
On the first day John has 5 ways to choose from.
2nd Day:
On the second day John has 5×5 ways to choose from.
(Since repetition is allowed)
3rd Day:
On the third day John has 5×5×5 ways to choose from.
4th Day:
On the fourth day John has 5×5×5×5 ways to choose from.
5th Day:
On the fifth day John has 5×5×5×5×5 ways to choose from.
Total ways = 5×5×5×5×5
Total ways = 5^5
Total ways = 3125
Therefore, the correct option is C) 5^5
Answer:
Step-by-step explanation:
<u>The slope-intercept form:</u>
- y = mx + b, where m- slope, b- y-intercept
<u>Use point (5, -3) and m = -4/5:</u>
- -3 = -4/5*5 + b
- -3 = -4 + b
- b = -3 + 4
- b = 1
<u>The line is:</u>
Answer:
The correct answer is A.
Step-by-step explanation:
We are given:
The measure of two complementary angles are in the ratio 1 : 5
We know that the sum of complementary angles is 90 degree
Let the first angle be x
Let the other angle be 5x
Thus the equation we get:
x+5x = 90 degree
6x=90 degree
Divide both sides by 6
6x/6= 90/6
x= 15 degree
Now put the value of x in 5x
5x = 5(15)
= 75 degree
Thus the correct option is 15 degree, 75 degree....
