Answer:
A
Step-by-step explanation:
Answer is the first choice. you can tell by the notation.
Answer:
- 4 1/2 + 3 1/4
-9/2 + 13/4
the lcm is 4
-18/4 + 13/4
=-5/4
= -1 1/4
Step-by-step explanation:
Answer: option A, 3x + 5
first, i rewrote it and removed the parentheses.
2x - 4 + x + 9
then, i collected the like terms.
3x + 5
<em>Height of the pole (DC) is 57.2709m</em>
Step-by-step explanation:
Here, Wire DA and Wire DB supports a pole.
Given that Angle, A=54 , B= 72.
Also, AB = 23m
Now, Taking triangle BCD and Using basic trigonometry
Height of pole H = DC


Now, Taking triangle ACD and Using basic trigonometry


From figure, we know that
AC = AB + BC
AC - BC = AB = 23
Replacing values of AC and BC

Now, TanB= Tan72 =3.0776 and TanA = Tan54=1.3763




Thus, Height of thepole is 57.2709m
There are 8 quarters, 40 nickels, 20 dimes and then there are 200 pennies
I hope this helps
