Answer:
B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
B) 23
Add what you know together, 6 + 2 + 2 + 2 + 3.5. Fill in what you don’t by looking at other sides. 3.5 + 2 + 2.
The solution would be like
this for this specific problem:
sin 54 degrees = Height/718.0624
Height = (sin 54 degrees)(718.0624) = 580.9 ft
So the height of the balloon is 580.9 ft. I am hoping that this

Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48

Step-by-step explanation:
Given
Soda = 10
Sprite = 4
Dr. Pepper = 3
Cherry Coke = 3
Required
Determine the probability of picking Dr. pepper the fourth and fifth
First, we need to sum up the number of drinks
First Selection: Dr. Pepper
Since its probability without replacement;
<em>At this stage: Dr. Pepper = 2 and Total = 19</em>
Second Selection: Cherry Coke
<em>At this stage: Dr. Pepper = 2; Cherry Coke = 2 and Total = 18</em>
<em></em>
Third Selection: Cherry Coke
<em>At this stage: Dr. Pepper = 2; Cherry Coke = 1 and Total = 17</em>
<em></em>
Fourth Selection: Dr. Pepper
<em>At this stage: Dr. Pepper = 1; Cherry Coke = 1 and Total = 16</em>
<em></em>
Fifth Selection: Dr. Pepper
<em></em>
<em>Multiply the calculated probabilities, to give the required probability</em>
