To solve this problem you must follow the steps below:
1. The problem says that:
- The<span> hot air balloon is at an altitude of 240 feet.
- It descends at 30 feet per minute.
2. Therefore, you have:
x: the time in minutes.
y: the altitute in feet.
3. Keeping all this information on mind, you can write the following equation:
y=240-30x
4. Therefore, as you can see, the answer is:
</span>
y=240-30x
Answer:
y=-2/3x+8
Step-by-step explanation:
Okay, so the formula to find slope is y=mx+b, so we would start off by writing that. M in the equation represents the slope and b represents the y-intercept.
y=mx+b
y=-2/3x+b
y=-2/3x+8

Answer:
Height is 10 units
Volume is 785 cubic units
Step-by-step explanation:
We are given;
Diameter of a cylinder as 10 units
But, radius = d/2
= 5 units
Height is twice its radius,
Thus, Height = 10 units
We can get the volume;
Volume of a cylinder = pir²H
Taking pi to be 3.14
Then;
Volume = 3.14 × 5²× 10
= 785 cubic units
Thus, the volume of the cylinder is about 785 cubic units
Answer:
sx-rx
Step-by-step explanation:
Since s, r, and x are unknown variables, you just multiply them. s × x = sx.
r × x = rx. then when you put the together, it will look like this:
sx-rx
Because the circumference of a circle is the diameter times 3.14, all you have to do to get the diamater is reverse it and divide the circumference by 3.14
