Given :
Two similar triangle.
To Find :
The ratio of the area of triangle abc to the area of triangle edc.
Solution :
ΔABC ~ ΔAPQ (AA criterion for similar triangles)
Since both the triangles are similar, using the theorem for areas of similar triangles we have :
Therefore, ratio of area of triangle is 1.4 .
Answer:it will it take him 6 minutes to cook the rest.
Step-by-step explanation:
The chef needs to cook a total of 9 potatoes. He has already cooked 7 potatoes. That means that the number of uncooked potatoes left is total number of potatoes - number of cooked potatoes. It becomes
9-7 = 2 potatoes
If each potato takes 3 minutes to cook, this means that 2 potatoes will take 3 minutes × 2 j = 6 minutes
Since there are only 2 potatoes left uncooked, it will it take him 6 minutes to cook the rest.
Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585 
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is 
. However, 3.14 will be used instead of 
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like 
. Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is 
. However, 3.14 will be used instead of for this formula.
For the area, plug the radius into the formula, and the formula will look like 
. Then, solve the equation, and the answer will be 63.585 .
S(x) = x^3
Make x the subject:-
x = (S(x))^ 1/3 = ∛ S(x)
Inverse is ∛ S(x)
Answer:
B. Biased Sample.
Step-by-step explanation:
The population is not only made of mothers, but there are fathers, sons, daughters, brothers and sisters, and a lot of other people. By selecting only mothers, it gears the survey to be biased towards a certain type of thinking.
