Answer: Cruz's biking is 16 miles per hour and his running speed is 10 miles per hour.
Step-by-step explanation:
Let x represent Cruz's speed when running.
He left his house at 6:00 and ran until 7:30. This means that the time spent while running is 1hour 30 minutes = 1.5 hours.
Distance = speed × time
Distance covered while running would be
1.5 × x = 1.5x
Then he rode his bike until 9:45. This means that the time he spent riding his bike is 2hours 15 minutes = 2 hours + 15/60 = 2.25 hours
His speed when biking was 1.6 times his speed when running. It means his speed when biking would be
1.6 × x = 1.6x
Distance covered while riding would be
1.6x × 2.25 = 3.6x
He covered a total distance of 51 miles. Therefore,
1.5x + 3.6x = 51
5.1x = 51
x = 51/5.1 = 10 miles per hour.
His biking speed would be
1.6 × 10 = 16 miles per hour.
Easy 4,500 - 750x = y x is the number of months which is the independent variable (yes this is science in math) y which is the dependent variable which is the amount he has after x amount of months Ex: 2= x 4500 - 750 x 2 = 4500 - 1500 = $3,000 left in his account
Answer:
37.625 square yards or 37⅝ square yards
Step-by-step explanation:
Area of the triangle = ½*base*height
Where,
base = 10¾ yd = 10.75 yds
height = 7 yds
Substitute the value of each variable into the equation:
Area = ½*10.75*7
Area = 37.625 square yards or 37⅝ square yards
The expression equivalent to <span> ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
</span><span> ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)
Answer: </span>12^(1/2)a^3b^(3/4)
