Ill review each sentence and find their mistakes.
<span>A. The 5 ft plank was too short and needed to be recut.
</span>In this sentence, "ft" needs a period at the end so therefore this sentence isn't correctly punctuated. (a is not the answer)
B. Mr. Langan requested a wake-up call for 9:00 a. M. on Saturday.
In this sentence, the a.m is punctuated incorrectly so this isn't correct either. (b is not the answer)
C. Why was there such noise at 6:00 AM?
Here, it is punctuated correctly. Looks like it is the correct answer.
D. Dr. Vaughn gave Mrs Vaughn a pearl necklace for their tenth anniversary.
In this sentence, "Mrs." didn't have a period at the end (d is not the answer).
So the answer was found and it is C because it is punctuated correctly. :)
-.66 this is because when you put it into a scientific calculator sin then -7 and round up you get -.66
2x + 3 = -1
-3 = -3
2x = -4
— —
2 2
x = -2
Hope this makes sense and helps :)
Answer:
291 cm³
Step-by-step explanation:
The volume (V) of the blue cuboid is calculated as
V = lbh ( l is length, b is breadth, h is height )
Here l = 11, b = 5 and h = 5, thus
V= 11 × 5 × 5 = 275 cm³
The volume (V) of the green cubes is calculated as
V = s³ ← s is the measure of the side
Here s = 2 and since there are 2 of them, multiply by 2, that is
V = 2 × 2³ = 2 × 8 = 16 cm³
Thus total volume of figure = 275 + 16 = 291 cm³
<span>20 is 5*4=20 ; 5 + 4 = 9</span>
