To find the mean, add up the numbers and divide the answer by the number of numbers you added up.

1) 95 + 18 + 51 + 1 + 22 + 5 = 192
    192 / 6 = 32
    The mean of the numbers is 32.

2) 67 + 103 + 94 + 65 + 18 + 114 + 94 + 63 + 94 + 27 = 739
    739 / 10 = 73.9
    The mean of the numbers is 73.9.

    To find the median, line up all the numbers from least to greatest. Then see          which number is in the middle. If there are two numbers in the middle, find            the mean of the two numbers.

    18, 27, 63, 65, 67, 94, 94, 94, 103, 114
    67 and 94 are in the middle. The mean of 67 and 94 is 80.5.
    The median is 80.5.

Simone bought 3.42 pounds of green apples and 2.19 of red apples.She used 3 pounds to make a pie.How many pounds of apples are l
Dima020 [189]
Well, since she bought 3.42 pounds of green apples, then you can subtract 3 lbs off of that, so she bought .42 lbs of green apples, and 2.19 lbs red apples
So now, you just need to add .42 and 2.19
.42 + 2.19 = 2.61, so she has 2.61 lbs of apples left
Hope this helped!

Answer:

...

against the wind, an airplane travels 3640 km in 7 hours.

with the wind, the same plane travels 6000 km in 6hrs.

...

let speed of plane in still air be x mph

speed of wind be y mph.

..

t=d/r

..

against wind speed = x-y mph

with wond speed = x=y mph

...

3640/(x-y)=7

3640 = 7x-7y

/7

520=x-y.....................1

...

6000/x+y = 6

6000 = 6x+6y

/6

1000=x+y.....................2

...

Add (1) & (2)

2x=1520

/2

x=760 mph speed of plane in still air

...

plug value of x in 2

1000=760+y

100-760=y

240 = y

240 mph speed of wind

A 70ft ladder is mounted 10ft above the ground on a fire truck. The bottom of the ladder is 40ft from the wall of a building.the
Luda [366]
Please refer to my attachments for visual guidelines.
We are going to solve your problem by using the pythagorean theorem, a^2+b^2 = c^2, where a and b are the legs of the triangle, and c is the hypotenuse (the longest side).

The length of the ladder is equal to 70ft (hypotenuse); one leg is the distance between the wall and the bottom of the ladder - 40 ft, the other leg is unknown for it is the distance between 10 ft above the ground and the top of the ladder-represented by "x". Using pythagorean theorem, a^2+b^=c^2, we have x^2+40^2 = 70^2. Solving the exponents, we have x^2 + 1600 = 4900.

Isolating the variable x, we have x^2 = 4900-1600. Futher simplying, x^2 = 3300. Thus, x = √3300 or 57.4456264654 ft.

Adding 10 ft to x, therefore, the top of the leadder is 67.4456264654 ft off the ground.
