we know that
To find out the mean change of altitude, divide the total change by the amount of time it takes
so
---> is negative because the airplane is descending
Answer:
-1/4x(-4/3) = 1/3
You can use caculator. It's really easy
A) 24 - Count the boxes
B) 18 - count the boxes. 1/4 of a box is 1/4 of 8....so 2.
For C and D use the equation:
x + 3x = 32
4x = 32
x = 8
We know x (Wednesday) is 8, and Thursday is 3x. That means Thursday is 24.
C) 8
D) 24
The answer is D.
Explanation: since the -7 is inside with the x it move the graph 7 units to the right (since it’s a negative sign). If it is outside the x it would move the graph up or down depending on if its a negative or positive number
We first calculate Pablo's height .
4 = 100%
x = 1% (Where x is 1% of Sandra's height.)
cross multiplying the equation, we get:
100x = 4 → x = 4/100 → x = 0.04
If 1% = 0.04, then 10% will be 0.04 × 10 = 0.4
Pablo's height is 4 + 0.4 = 4.4 feet.
Now we repeat the above steps to get Michal's height from Pablo's height
4.4 = 100%
x = 1% so:
100x = 4.4 → x = 4.4/ 100 → x = 0.044
If 1% = 0.044, then 8% will be 0.044 × 8 = 0.35
Michael's height is 4.4 + 0.35 = 4.75 feet.
