A balloon is 30 yards above the ground. It starts to float upwards, and the altitude increases at a rate of 5 yards per minute. Enter the altitude, in yards, of the balloon after 20 minutes.

Answers

Answer 1
Answer:

a=20(5)+30

20*5=100

100+30=130

Altitude: 130 yards.
Answer 2
Answer:

Final answer:

The balloon's altitude increases by 5 yards each minute. So, after 20 minutes, the balloon has ascended 100 additional yards. If it was initially 30 yards above the ground, it is now at an altitude of 130 yards.

Explanation:

Based on the provided information, the altitude of the balloon changes at a rate of 5 yards per minute. At the beginning, the balloon is 30 yards above the ground. This initial altitude is increased by the amount of change happening every minute. Therefore, after 20 minutes of continuous upward movement, the change in altitude is 20 minutes * 5 yards/minute = 100 yards. Thus, the final altitude of the balloon becomes the sum of its initial altitude and the change, which is 30 yards + 100 yards = 130 yards.

Which shows 54^2 − 46^2 being evaluated using the difference of squares method

Answers

We use the formula: a^2 - b^2 = (a - b )(a + b);
54^2 − 46^2 = (54 - 46)(54 + 46) = 8 x 100 = 800;

What is LK rounded to the nearest hundredth? show work if you canAlso what is JK TO THE nearest hundredth? show work if you can

Answers

LK is actually the opposite side. What you've also been given is the length of the hypotenuse and an angle (20 degrees).

We know that:

sin(β)=Opposite/Hypotenuse=O/H

This is because of the famous:

SOH CAH TOA

-----

We can solve the problem by writing down:

sin(20)=LK/8.5

This means that:

LK = 8.5 * sin(20)

LK = 2.91 metres (to 2 decimal places)
