Well knowing these are both obtuse angles of the same shape and size we can begin. were looking to show AC is equal to DF we start by connecting A to C. A goes to C and makes this half an Oval shape along the bottom line now try connecting A to B and C to B AB and CB are not the same as AC and since these angles are the same shape and size we know DF should do the same so now we connect D to E and F to E similar to AC they do not match nor do they match AC itself leaving us to compare D to F after we do this we see that it creates the same sized half an oval as AC showing us that they are equal. :)
The side lengths of a triangle are 9, 12, and 15. Is this a right triang
O A. Yes, because 9² + 12² > 15².
O B. No, because 9 + 12 ‡ 15.
OC. Yes, because 9² + 12² = 15².
OD. No, because 9² + 12² # 15².
Answer is the A
Answer:
4.07
Step-by-step explanation:
11 1/5 divided by 2 3/4
= 11 1/5 ÷ 2 3/4
= 56/5 ÷ 11/4
= 56/5 × 4/11
= (56*4) / (5*11)
= 224/55
= 4.07
The best estimate of 11 1/5 divided by 2 3/4 is 4.07
-20=-4x-6x
First combine like terms.
-20=-10x
Divide by -10 on both sides
X=2
Answer:
19/37
Step-by-step explanation:
The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor
Total number of people in the faculty =
9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors
= 37 people
Hence,
The probability of choosing a professor or an instructor
= P( Professor) + P( Instructor)
= 9/37 + 10/37
= 19/37
