<h3>
Answer: -3/4 (choice C)</h3>
==================================================
Explanation:
Think of a whole cake or pizza. Now slice it into 4 equal pieces. This represents 1 is the same as 4/4.
Adding on another quarter slice gets us 4/4+1/4 = 5/4
In other words, the mixed number 1 & 1/4 is the same as the improper fraction 5/4.
So 1 & 1/4 = 5/4
This then means -1 & 1/4 = -5/4 because we multiply both sides by -1.
Now we'll add on 1/2, which is the same as 2/4, like so
(-1 & 1/4) + 1/2
-(1 & 1/4) + 2/4
-(1 + 1/4) + 2/4
-1 - 1/4 + 2/4
-1 + (-1/4 + 2/4)
-1 + 1/4
-4/4 + 1/4
-3/4
which points us to choice C as our final answer
Notice how if we started at -5/4, and moved to the right 2 tickmarks, we arrive at -3/4. Each tickmark represents 1/4 of a unit, so two of them is 2/4 = 1/2.
Side note: -3/4 converts to the decimal -0.75
Is probably C and D good luck!
And have a nice day
Area of a circle can be calculated using the following formula
Area = πr²
where π = 3.14 and r - radius of circle
Area of the whole circle is for a central angle of 360°.
We are asked to find the area of a sector. Sector is when 2 arms enclose a central angle by which one arm has rotated.
1 radian = 57.3°
2.4 radian = 57.3 x 2 = 137.52°
Area for 360° = πr²
area for 137.52° = πr² / 360° x 137.52 = π x 6 cm x 6 cm x 0.382 = 13.752 cm²
Answer:
31/40 of the trail
Step-by-step explanation:
he completed 9/10 of the trail (or 72/80 because 9*8 is 72)
He went back 1/8 of the trail (or 10/80 because 1*10 is 10)
72-10 is 62
he went 62/80, simplified is 31/40 of the trail
