Answer:
160
Step-by-step explanation:
60% of a + 24 = 3a/4
=> 60a/100 + 24 = 3a/4
=> 3a/5 + 24 = 3a/4
=> 3a / 4 - 3a/5 = 24
=> ( 15a - 12a) / 20 = 24
=> 3a / 20 = 24
=> a = 24 × 20 / 3
=> a = 8 × 20
=> a = 160
Answer:
2500 meals in 20 hours.
Step-by-step explanation:
The easiest point to see is (2,250). The other point (since you need 2) is the origin. This is a graph. It does not require any greater accuracy than looking at the point that is chosen.
x = 2
y = 250
k = ?
y = k*x equation
250 total meals packed = k * 2 hours Substitute values
k = 250 /2
k = 125 meals / hour
Let x = 20 hours
k = 125 meals / hour
y = ?
y = 125 * 20
y = 2500 meals
A squared +b squared =c squared
so 24x24=576
18x18=324
576+324=900
square root of 900=30
the diagonol is 30
Answer:
The component form of the velocity of the airplane is
.
Step-by-step explanation:
Let suppose that a bearing of 0 degrees corresponds with the
direction and that angle is measured counterclockwise. Besides, we must know both the magnitude of velocity (
), in miles per hour, and the direction of the airplane (
), in sexagesimal degrees to construct the respective vector. The component form of the velocity of the airplane is equivalent to <u>a vector in rectangular form with physical units</u>, that is:
(1)
If we know that
and
, then the component form of the velocity of the airplane is:
![\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right]](https://tex.z-dn.net/?f=%5Cvec%20v%20%3D%20389.711%5C%2C%5Chat%7Bi%7D%20-225%5C%2C%5Chat%7Bj%7D%5C%2C%5Cleft%5B%5Cfrac%7Bm%7D%7Bs%7D%20%5Cright%5D)
The component form of the velocity of the airplane is
.
