Answer:
Step-by-step explanation:
To solve the problem, you must expand the trigonometric expression using the information given.
Answer:82cm^2
Step-by-step explanation:
Area of shape=area of big rectangle + area of small rectangle
Length of big rectangle=10
Width of big rectangle=7
area=length x width
area of big rectangle=10x7
area of big rectangle=70
Length of small rectangle=4
Width of small rectangle=10-7=3
Area=length x width
area of small rectangle=4x3
area of small rectangle=12
Area of shape=70+12
Area of shape=82cm^2
1m=100cm
1.6m=160cm
160-10=150
He was 150cm one year ago
Answer:
The missing factor is 1.
Step-by-step explanation:
, where y is the unknown factor.
You can solve this equation for y.
Divide both sides by 7:
Divide both sides by 4:
The missing factor is 1.
You can also tell just by looking on this particular problem. 
, so the missing factor can't be anything other than 1.
3. 5/12 * 4/9 = 5/27
4. x - 2 2/5 = 5 13/20
x - 12/5 = 113/20
x = 113/20 + 12/5
x = 113/20 + 48/20
x = 161/20 or 8 1/20
