Answer:
A, D and E
Step-by-step explanation:
Since Rectangle B is a scaled copy of Rectangle A, the ratios must remain the same which is:
A. 9:3
= 3:1 ✅
B. 8:2
= 4:1 ❌
C. 10:4
= 5:2 ❌
D. 13.5:4.5
= 3:1✅
E. 90:30
= 3:1✅
Hence,
A, D and E have the same ratios. Hence, these are the possible measurements of Rectangle B.

Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.
Answer: x=5 bc 5 times 5 is 25
Ste-by-step explanation:
Answer:
the object will fall 5060 feet in 10 second.
Step-by-step explanation:
g= 9.8m/s^2 and 9.8×3.33=32.67 feet/s^2.
initial velocity (u)= 16 feet/second
time taken(t)=10 second
final velocity(v)= ?
now,
V= u+ GT
=16+32.67×10
=342.67feet/second
again
distance covered= VT+1/2gt^2
=342.67×10+1/2×32.67×100
=3426.7+1633.33
=5060 feet
