Answer:
52 Degrees
Step-by-step explanation:
Subtract 29 (lower number) from 81 (higher number). This will often give you the difference (52) between the two measurements.
Total ratio is 1 + 3 + 5 = 9
Share for 1 = 1/9 × 144
= 16kg
Share for 3= 3/9 × 144
= 48kg
Share for 5= 5/9 × 144
= 80kg
Proof= 80 + 48 + 16 =144
The percent of people of smoke cigarettes is 20.9%..
Answer:
It will take turtle
to reach the pond.
Step-by-step explanation:
Given:
A turtle can walk 1/12 of a kilometer in an hour.
The turtle is 1/5 of a kilometer away from a pond.
Now, to find the time it will take the turtle to reach the pond.
<u>Speed</u> of turtle = 
<u>Distance</u> of turtle from the pond = 
Now, to get the time it will take turtle to reach the pond we put formula:





Therefore, it will take turtle
to reach the pond.
The rectangle problem:
First, create some variables.
w = width
l = length
Then you know that the length is 3 times the width, so
l = 3w
The equation for perimeter is
P = 2(l+w)
Now you use substitution, substituting the 3w for l because you found that earlier.
P = 2((3w) + w)
And simplify.
P = 2(4w)
P = 8w
And you know P = 30 because they told you that.
30 = 8w
w = 15/4 inches, or 3.75 inches
Now substitute that value back into that first equation,
l = 3w
l = 3(15/4)
l = 45/4 inches, or 11.25 inches.
The dimensions are 11.25in for length and 3.75in for width.

The volleyball problem:
100 minutes of stretching and scrimmaging combined, and you know 10 have to be stretching, so 90 is scrimmaging.
s = scrimmaging
T = total time
s = 2/3T (they gave you this)
90 = 2/3T
T = (90*3)/2
T = 270/2
T = 135 minutes, or 2 hours and 15 minutes.
