Answer:

The maximum number of pounds p is 224
Step-by-step explanation:
Let
p ----> the maximum number of pounds he can pull without going over the weight limit
we know that
121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds
In this problem the word "at most" means "less than or equal to"
so
The inequality that represent this situation is

solve for p
subtract 121 both sides


therefore
The maximum number of pounds is 224
-(3/4) (12)+1 = -9+1=. -8
Answer:
for Part A
Answer is C.
Step-by-step explanation:

Here the angle, a is 60°, Opposite is 20 and adjacent is x.
Therefore we have,

Making x the subject gives us

Part B
Value of x to the nearest tenth

Answer:

Step-by-step explanation:
Since the divisor of
is in the form of
use what is called Synthetic Division. Remember, in this formula, −c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
−1| 2 1 0 1
↓ −2 1 −1
__________
2 −1 1 0 → 
You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [2x³ + x² + 1]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than the leading coefficient of your dividend, so that 2 in your quotient can be a 2x², the −x follows right behind it, and bringing up the rear, 1, giving you the quotient of 2x² - x + 1.

Answer:
At 4:48 p.m.
Step-by-step explanation:
angle between hands of the clock is given by
θ= | 30H- 11/2M |
Where H and M are hours and minutes respectively.
H=4
θ= | 30×4- 11/2M |
⇒144°= | 120- 11/2M |
solving Above equation we get M= 48 minutes
Time = 4:48 p.m.
therefore between 4 and 5 p.m. at 4:48 p.m. the angle between minute and hour hand is 144°
