Answer: Aproximately 2,525 balloons
Step-by-step explanation:
1. Find the volume of a balloon with the formula given in the problem, where 
is the radius (
), then:
2. Convert the volume from m³ to lliters by multiplying it by 1,000:
3. You know that that 1 liter of helium can lift 1 gram and that Ryan weighs 5 stone and 5 pounds. So you must make the following conversions:
1 g=0.0022 lb
From 5 stones to pounds
4. Then Ryan's weigh is:
5lb+70lb=75lb
5. Then, if 1 liter of helium can lift 0.0022 lb, to lift 75 lb (which is the weight of Ryan) they need:
6. Then, to calculate the aproximated number of balloons they need to make him float (which can call 
), you must divide the liters of helium needed to lift the weight of Ryan by the volume of a balloon, then the result is:
≈2,525 balloons.
Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
False.
The Rational Root theorem states that P is a factor of the constant term and q is a factor of the leading coefficient.

Answer:
A. 4.5
Step-by-step explanation:
According to my graphing calculator, e^1.5=4.5 which is rounded to the nearest tenth.
Answer: e^1.5 = 4.482
Step-by-step explanation:
Given:
We need to find the value of function at x=1.5
Put x=1.5 into f(x)
Now we will verify the result using graph.
First we draw the graph of f(x) and a vertical line x=1.5
Please see the attachment for graph.
Hence, The value of
