Answer:
58,187.5 m²
Step-by-step explanation:
1 cm : 25 m
7 cm = 25 × 7 m
7 × 25 = 175 m
13.3 × 25 = 332.5 m
area = 332.5 m × 175 m
Answer:1/3 to the 3rd = 1/9 units
Step-by-step explanation:
a^3 = volume of a cube part 2: 1/2 to the power of 1/2
Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360
Answer:
33) $8440
34) $67,964.62
Step-by-step explanation:
33) The interest on 1 for 270 days is ...
... I = Prt = 1×0.09×(270/360) = 0.0675
so the proceeds from a loan with a face value of 1 will be
... 1 - 0.0675 = 0.9325
We want to find the face value of a loan with proceeds of $7870.30, so we need to solve the equation ...
... $7870.30 = P×0.9325
... P = $7870.30/0.9325 = $8440
34) The discount is computed from ...
... I = Prt = 70,000×0.063×(24/52) ≈ 2035.38
Then the amount Smith will pay for the T-bill is ...
... $70,000 -2035.38 = $67,964.62
