Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.
P(Larger or blue) = 7/10. In a bag we have blue and red marbels, which are large and small as in the table shown in the image, the probability of taking a large or blue marble is 7/10.
The key to solve this problem is find the probability of the union events using the equation P(A∪B) = P(A) + P(B) - P(A∩B).
For this problem we have P(Large or Blue) = P(Large) + P(Blue) - P(Large and Blue). The total of the large ones is 25 and the small ones is 15, meaning that the sum of both is 40. P(large) = 25/40, P(Blue) 20/40, and P(Large and Blue) = 17/40
P(Large or Blue) = 25/40 + 20/40 - 17/40 = 28/40 dividing by 4 both terms of the fraction.
P(large or Blue) = 7/10
The angle sum property of a triangle is the sum of the interior angles of the given triangle.
The total sum of the interior angels of a triangle =180
Answer:
No
Step-by-step explanation:
To tell whether two triangles are similar or not, we can compare their side lengths or angle measures
in this case, only angle measure are given so will compare those:
m<F = m<I but this is not enough, we need to compare other angles as well
m<H is not equal to m<G
The sum of interior angles in a triangle is equal to 180
so the measure of angle J
100+55+J = 180
J = 25
The measure of angle E
100+35+E = 180
E = 45
Now, neither of these angles are equal to each other so we can conclude that these triangles are not similar.
