Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
You turn 4 and 3/5 into 4 and 9/15 and you turn 2 and 1/3 into 2 and 5/15 and then you subtract to get 2 and 4/15.
Answer:
73.4 cm^2
Step-by-step explanation:
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Hello,
<u>We have :</u>
27 = 3³ = 3 × 3 × 3
³ = × ×
<u>So :</u>
The cube root of 27³ is :
3 × = 3
( because : (3)³ = 27³ )
<u>We have :</u>
8 = 2³ = 2 × 2 × 2
<u>So :</u>
The cube root of 8 is : 2
with 
and 
<u>We have :</u>
Have a nice day :)
