Answer: 9 inches
Step-by-step explanation:
Let r be the length of the red ribbon
r is 6 inches less than 15 inches
r = 15 - 6 = 9 inches
Answer:
-1 23/64
Step-by-step explanation:
First change the 2 mixed numbers to single fractions:-
3 5/8 = (3*8+ 5) / 8 = 29/8
-2 2/3 = - (2*3 + 2/ 3 = -8/3
so we have 29/8 / -8/3
Invert the -8/3 then multiply:-
= 29/8 * -3/8
= -87/64
= -1 23/64 (answer)
<span>The answer is 97. The first expression is 1+4=5. In the next expression, both numbers are increased by 1 while their sum is increased by 7: (1+1)+(4+1) = (5+7). 2+5=12. In the next expression, both numbers are increased by 1 again, but the sum is increased by the next odd number (which is 9): (2+1)+(5+1)=(12+9). 3+6=21. So, the series will look like this: 1+4=5. 2+5=12. 3+6=21.4+7=33. 5+8=46. 6+9=61. 7+10=78- 8+11=97.</span>
Answer:
7.68 s
Step-by-step explanation:
The vertical motion formula is:
<u>Where:</u>
h(t): is the final height = 0
h(0): is the height of the cliff = 104 foot
v(0): is the initial velocity = 110 ft/s
g: is the gravity = 9.8 m/s² = 32.15 ft/s²
Hence, from the vertical motion formula we can find the time that will take the rocket to hit the ground:
We have two solutions:
t₁= -0.84 s
t₂ = 7.68 s
We will take the positive value, thus the time that will take the rocket to hit the ground is 7.68 s.
I hope it helps you!
The negative 7 is the correct answer
