During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 7
kondaur [170]

Answer:

13 centimeters per day.

Step-by-step explanation:

We have been given that during summer, the water level of the river increased by 78 centimeters in 6 days. We are asked to find the water level increase rate in centimeters per day.

To find the water level increase rate per day, we will divide total increase by total days as:

\text{Water level increase rate per day}=\frac{78\text{ cm}}{6\text{ days}}

\text{Water level increase rate per day}=\frac{13\text{ cm}}{\text{ day}}

Therefore, the water level increase rate is 13 centimeters per day.

The circumference of the circle-shaped rug is 69.08 inches.
adelina 88 [10]
We can find the diameter by dividing the circumference by 3.14
d = 22

Thus, our radius is 11.
r = 11

Now, let's use the area formula (3.14 \cdot r^2) to solve for the area.
a = 3.14 \cdot (11^2) = \boxed{379.94}

Please help me on these questions, Thanks

29).  The 'six' is the same as (6 x 5) = 30 fifths.
So  six and three fifths = (30 + 3) fifths  =  thirty-three fifths.

30).  The 'eight' is the same as (8 x 6) = 48 sixths.
So  eight and five sixths = (48 + 5) fifths=  fifty-three sixths.

31).  Twenty-seven of the thirds are the same as  (27/9)  = 3 .
That leaves a remainder of 2 thirds.
So  twenty-nine thirds are the same as  3 and 2/3 .

32).  Thirty-two of the fourths are the same as  (32/4) = 8 .
That leaves a remainder of one fourth.
So  thirty-three fourths are the same as  4 and 1/4 .
