Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
Answer:
x = 4
Step-by-step explanation:
Since the triangle is 45-90-45, x = 4.
Solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7
<u>Solution:
</u>
Need to determine solution of following equation’
-(5-(a+1)) = 9-(5-(2-3))
Means need to solve the above equation for "a"
On solving operation in most internal bracket we get
-(5-(a+1)) = 9- ( 5 – ( -1))
On opening inside brackets we get,
-(5 – a – 1 ) = 9 – ( 5 +1 )
On solving remaining brackets we get
-5 + a + 1 = 9 – 6
=> a – 4 = 3
=> a = 4 + 3 = 7
=> a = 7
Hence solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7
11/3, 25/7, 18/5. Multiply to find common denominators.
Answer:
z=12
Step-by-step explanation:
It is given that x varies jointly as y and z, it means
where, k is the constant of proportionality.
It is given that x=8 when y=4 and z=9
Divide both sides by 36.
The value of k is 2/9.
We need to find the value of z when x=16 and y=6.
Substitute x=16 and y=6 in the above equation.
Multiply both sides by 3.
Divide both sides by 4.
Therefore, the value of z is 12.
