Find the accelartion:

1 answer:

6 0

A. Man runs (> 2.2 m/s is running) uphill at 6 m/s (???) and decelerates to walking at 2.0 m/s near the top, all in 5 minutes, assuming he ran in a straight line.

Acceleration is (final velocity-initial velocity (m/s) )/time (s)
=(2-6)/(5*60)=-4/300= -0.0133 m/s^2

B. Car goes east for 300 km in 45 min.
Velocity
=300*1000 m / (45*60) s due east
=300000/2700 m/s due east
=111.1 m/s due east
(is it an airplane? A cesna cruises at 63 m/s (226 km/h) )

Jace's average gross pay is $1,630.00 bi-weekly. Determine how many years it will take Jace to earn his first million dollars.

vesna_86 [32]

The number of years it will take to earn his first million is 24 years

Average bi-weekly gross pay = $1,630

Bi-weekly = 2 weeks

Number of 2 weeks(bi-weeks) in a year = 26 bi-weeks

The least million he can earn is $1,000,000

Let the number of years = n

We could use the equation :

Least million = gross pay × (Number of bi-weeks × number of years)

1000000 = 1630 × (26n)

1000000 = 42380

Divide both sides by 34230

1000000 / 42380 = n

n = 23.59

The least number of years is 24.

Calculate the area of quadrilateral ABCD. State the units of your answer.

cluponka [151]

Answer:

158.76 cm²

Step-by-step explanation:

Quadrilateral ABCD is composed of 2 right triangles

Construct the line BD, then

Δ ABD and Δ BCD are the 2 right triangles.

The area (A) of a triangle is calculated using

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Δ ABD with b = 18 and h = 7.5

A = $\frac{1}{2}$ × 18 × 7.5 = 9 × 7.5 = 67.5 cm²

Δ BCD with b = 15.6 and h = 11.7

A = $\frac{1}{2}$ × 15.6 × 11.7 = 7.8 × 11.7 = 91.26 cm²

Thus

area of ABCD = 67.5 + 91.26 = 158.76 cm²
