Answer:
15
Step-by-step explanation:
the total number of players = 10 × 12 = 120
Forming 8 equal groups from 120 players
= 
= 15
There are 15 players in each team of 8
No two numbers add up to 3 and multiply to -2
A) Scale factor:
Divide 2 congruent sides:
24 / 36 = 0.667
From PQR to XYZ is a 0.667 (2/3 as a fraction) scale factor.
B) Volume = (1/2 x base x side) x height:
Volume = 1/2 * 36 x 48 = 864 * 15 = 12,960 cubic inches.
C) Find the height of the prism:
7776 = (1/2 * base * sides) x height
7776 = (1/2 x 36 x 48) * height
7776 = 864 * height
Height = 7776 / 864 = 9 inches.
The scale factor is 2/3, the height of XYZ = 2/3 *9 = 6 inches.
Volume of XYZ = 1/2 x 24 x 32 = 384 x 6 = 2,304 cubic inches.
Answer:
C:30π cm
Step-by-step explanation:
The formula for the circumference of a circle is
C = 2πr
Since the radius is 15 cm, this makes 2r = 2(15) = 30 cm. This makes the circumference
C = 30π cm
Answer:
Step-by-step explanation:
5)
DG= 60 (whole)
DO= 4x-3 (Part)
OG= 2x+ 21 (Part)
4x-3+ 2x+21= 60
6x+18=60
6x=42
x=7
Using this we can solve for DO and DG
DO= 4*7-3
DO= 25
DG= 2*7+21
DG= 14+ 21= 35
6)
TB is whole
TU is part
UB is part
5x= 4x-1+2x-1
5x=6x-2
x=2
UB= 2*2-1= 4-1= 3
TU= 4*2-1= 8-1= 7
