Answer:
Hi I have this same question but I'm torn between certain and very likely it is on of those options.
Step-by-step explanation:
Imagine right triangle PHF, where P - park, H - home and F - football field, then PH, PF are legs and HF is hypotenuse . Denote point L to be library. You know that point L lies on the segment FH and FL=8, LH=2. Also you know that PL is an altitude to the hypotenuse.
Use the property of altitude drawn from the vertex of right angle to the hypotenuse (the length of the altitude is geometrical mean between legs' projections onto hypotenuse):
mi.
This means that the distance between park and libriry is 4 miles.
Consider right triangle PLF ( angle L is right angle and PF - hypotenuse). By the Pythagorean theorem,
mi. The distance between park and football field is 
miles.
Answer: the distance between park and libriry is 4 miles and the distance between park and football field is miles.
Answer:
let the numbet of formal attires with Clara be X
Clara lended susan 1/2 = X/2
Clara buys 4 = X/2 +4
Answer = X/2 + 4
( as the number of formal attires originakly with Clara is not specified)
Hello! So in order to solve this problem, it's best to start off making an equation. $18 + $.15x = $29.25
In this equation x represents the number of minutes she used. So now, we just have to solve for x.
First subtract $18 from both sides. Your new equation will be $.15x = $11.25. Then divide both sides by $.15 to get x by itself. $11.25/$.15 = 75.
So we can conclude that Bella spoke on the phone for 75 minutes this last month. Hope this helps!
Answer:
c) 15.33
Step-by-step explanation:
lets find the mean first
mean = sum of the data values / number of data (n)
= 75 + 83 + 96 + 100 + 121 + 125 / 6
= 600/6
= 100
Next, let 'x' represent each data value and 'a' represent the the mean
now, calculate the deviation from each data point
75 - 100 = - 25
83 - 100 = -17
96 - 100 = - 4
100 - 100 = 0
121 - 100 = 21
125 - 100 = 25
Then, find the absolute value of each deviation and sum them up
that is | a - x |
| -25 | + | -17 | + | -4 | + | 0 | + | 21 | + | 25 |
= 25 + 17 + 4 + 0 + 21 + 25
= 92
now, calculate the mean of the absolute value
92/6 = 15.33
