Bananas are $0.49 per pound, and you want to buy 5.5 pounds of bananas.
0.49 x 5.5 = 2.695 <span>≈ 2.70
</span>
So the final answer is 2.70 dollars for 5.5 pounds of bananas.
Answer:
8
Step-by-step explanation:
Opposite angles are equal so
4x+12=44
4x=32
x=8
Answer:
0.44 ft/sec.
Step-by-step explanation:
Let A is the bottom of the ladder and AB is the distance from the bottom of the wall i.e. B is the bottom of the wall. If C is the top of the ladder and BC is the height of the wall.
Now, Δ ABC is a right triangle and AC is the length of the ladder i.e. hypotenuse.
Now, AC² = AB² + BC² {From Pythagoras Theorem}
Now, differentiating both sides with respect to time t, we get
⇒
Now, given that
feet/sec.
Hence,
......... (1)
Now, given that AB = 9 ft. and AC = 15 ft.
So, 15² = 9² + BC²
⇒ BC² = 144
⇒ BC = 12 feet.
Now, from equation (1), we get
Therefore, the bottom of the ladder is sliding away from the wall at the rate of 0.44 ft/sec. (Answer)
Answer:
(x-5)*(x+5)
Step-by-step explanation:
= x^2 + 5x - 25 - 5x
= x^2 +5x - 5x -25
because +5x - 5x = 0 so
= x^2 + 0 - 25
= x^2 - 25
25 can be written as 5^2
= x^2 - 5^2
we know that a^2 - b^2 = (a-b) * (a+b)
so x^2 - 5^2
= (x-5) * (x+5)
Hope this help you :3
The answerssssssssssssss is 90.
