1) Ratio - 4:1
thus, 4x + 1x = 20
5x = 20
thus, x = 20/5 = 4
thus, x = 4
and, 4x = 16
Thus, the answer is (C) 16 boys and 4 girls
2) According to distributivity, a(b+c) = ab + ac
Thus, the answer is (C)
PI r SQUARED SOUNDS LIKE AREA TO ME,
IF YOU NEED A CIRCUMFERENCE JUST USE PI d
You never heard that song? XD
So do Pi x the radius, squared (12.25^2)
-round to 1 decimal place(?)
Answer:
Option (1)
Step-by-step explanation:
''A perpendicular bisector makes 90° with the other line segment and divides the segment into two equal parts."
From the given picture,
If 
is a perpendicular bisector of 
following properties must be followed.
1). m(∠DBC) = m(∠DBA) = 90°
2). AB ≅ BC
Therefore, additional information we will require is AB ≅ BC
Option (1) will be the answer.
Answer:
Ratio is 2:1
Step-by-step explanation:
The bigger triangle is ×2 bigger so ratios can be
2:1 , 4:2, 8:4 , 16:8 and so on
Answer: Choice B) SAS
=======================================================
Explanation:
The sides that have the double tickmarks are the same length. This forms one "S" of "SAS".
The square angles are 90 degree angles, or right angles. They are congruent. This forms the "A" of "SAS".
The overlapping sides are the same length, which forms the second "S" of "SAS".
The angle is between the two sides allowing us to use SAS. The order is important.
