Answer:
C =(43/55)R; C - R = 8t; 48 mi
Step-by-step explanation:
Let C = the distance a coyote can run in t hours.
Let R = the distance a rabbit can run in t hours.
(1) C = 43t
(2) R = 35t
A. <em>Two equivalent expressions
</em>
(a) C/R = 43/35
C = (43/55)R
(b) C – R = 43t – 35t
C – R = 8t
B. <em>Distance advantage of coyote
</em>
Let the difference D = C - R
D = 8t
D = 8 × 6
D = 48 mi
In 6 h, the coyote can run 48 mi further than the rabbit.
Answer:
d ≈ 6.41
Step-by-step explanation:
Given that F is inversely proportional to d² then the equation relating them is
F = ← k is the constant of proportion
To find k use the condition when F = 8, d = 6 , then
8 = = ( multiply both sides by 36 )
288 = k
F = ← equation of proportion
When F = 7 , then
7 = ( multiply both sides by d² )
d² × 7 = 288 ( divide both sides by 7 )
d² = ( take the square root of both sides )
d = ± ≈ ± 6.41
The positive value of d is 6.41 ( to 2 dec. places )
Answer:
541.17ft^2
Step-by-step explanation:
the total area of the garden is the sum of area of rectangle and half of area of circle
area of rectangle=(l)(h)=(23)(18)=414
area of semicircle=1/2pir^2
since r is half of h=1/2(18)=9
area of semicircle=1/2pi(9)^2=127.17
total area of garden=414+127.17=541.17 ft^2
