(c) 25=5x5
Answer:
429 beats
Step-by-step explanation:
The number of beats is proportional to the time of the song.
Convert the time to seconds to avoid recurring decimals.
4 minutes 12 seconds = 4×60+12=252 seconds
3 minutes 54 seconds = 4×60−6=234
seconds
Set up a direct proportion using equivalent fractions:
x234=462/252
←beats/←seconds
x=234×462/252
x=429 beats

Answer:
(1, -2)
(-8, -2)
Step-by-step explanation:
(1 , -6) and (-8 , -6)
1 - (-8) = 9
we know that the length of the side that we know the vertices is 9
from there we make an equation with the sum of the sides equal to the perimeter
we will have 2 times 9 and 2 times x beacause it is a rectangle
x + x + 9 +9 = 26
2x + 18 = 26
2x = 26 - 18
2x = 8
x = 8/2
x = 4
Now that we know the missing side we just have to add or subtract this value to the coordinate in and of the vertices we have and we will obtain the missing vertices
(1, -6 + 4)
(1, -2)
( -8, -6+4 )
(-8, -2)
First, we need her speed as it will serve as the slope of the equation.
Distance = 2 km
time = 18 min
Speed = 1/9 km/min
k = (1/9)t
Where k is the distance in km and t is the time in minutes.
