Answer:
12 en cada hucha
Step-by-step explanation:
(x+5) + (x-5) = 24
El 5 se cancela
2x= 24
x = 12
Antes de pasar las monedas: (7 en una hucha y 17 en la otra)
12-5 = 7
12 +5 =17
17+7 = 24
Given :
An expression (cos 6m)(cos 2m) .
To Find :
We need to express it in terms as sum or difference.
Solution :
We know,
cos( A + B ) = cosA cos B - sin A sin B
cos( A - B ) = cosA cos B + sin A sin B
Adding both the equations we get :
2cos A cos B = cos( A + B) + cos( A - B )
or
cos A cos B = cos( A + B) + cos( A - B )/2
Putting value of A = 6m and B = 2m in above equation, we get :
(cos 6m)(cos 2m) = cos( 6m + 2m ) + cos( 6m - 2m )/2
(cos 6m)(cos 2m) = cos(8m) + cos(4m)/2
Hence, this is the required solution.
Answer:
74.47%
Step-by-step explanation:
Divide the total number of students by the number who passed
passed/total
35/47
0.74468085
As a percent:
0.74468085*100=74.4680851
Rounded to the nearest hundreth:
74.4680851
74.47%
So, 74.47% passed the geometry test
Hope this helps! :)
Answer:
area = (1/2)|Ax(By-Cy) +Bx(Cy-Ay) +Cx(Ay-By)|
= (1/2)|2(3-6) +3(6-1) +1(1-3)| = (1/2)|-6 +15 -2|
area = 7/2

5.25 -0.75 a is the expression, but to answer the question on the paper you would plug in the number of belts being made into where the variable a is. Hope this helps!
