Answer:
3.6cm
Step-by-step explanation:
Given data
We are given that the dimension of the photo is
Height= 15cm
Width= 9cm
That is
15cm height will make 9cm width
hence 6cm height will make x widht
cross multiply
9*6= 15*x
54= 15x
x= 54/15
x= 3.6cm
Hence the width will be 3.6cm
Answer:
Adding 7 to both sides of the equal sign
Step-by-step explanation:
Answer:
z/y
Step-by-step explanation:
when dividing with exponents, you simply subtract the variables w exponents
y^5 - y^6 = y^-1 (which is equal to 1/y)
z^3 - z^2 = z^1 (which is equal to z/1)
1/y * z/1 = z/y
We will use the formula:
Area = 1/2*a*c*sinB
where a and c are the length of the sides and B is the angle between those 2 sides
Area = 1/2*5*8*sin42
Area = 20*sin42
sin 42 = <span>0.669130606359
Area = </span>13.38261212718
Rounded to the nearest tenth Area is equal to 13.4
