<span>The summer solstice is the day of the year when the sun is the farthest north, over the Tropic of Cancer, 23.44 degrees (or 23 degrees 26 minutes) north of the equator.
On that day, all locations north of the Arctic Circle experience 24 hours of daylight.</span>
Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
It’s Levi because it’s clearly written that Levi is a beginner. Hope that works!
The SAT helps prepare for the ACT
To get the formula for the principal, we will use the
formula for the interest and derived it from there:
I = Prt is the equation then it will be P = I /rt since we
are looking for the principal.
P = I /rt
= $500 / (0.145 x 240/360)
= $500 / 0.0967
= $5170.63
To check:
I = Prt
= $5170.3 x 0.145 x 240/360
= $499.8 or $500
