Answer:
first blank is 3
second blank is 126
Step-by-step explanation:
the ratio is 2:3 so you must keep that the same in the table
x=9 units, y=12 units, u=24 units and v=32 units
Step-by-step explanation:
The question is on similarity.
The ratio of corresponding sides should be equal for the triangles to be similar.
Finding x
20/5=(3+x )/3
apply cross product
60=15+5x
60-15=5x
45=5x
45/5=x
9=x
Finding y
20/5=(4+y)/4
Apply cross product
80=20+5y
80-20=5y
60=5y
60/5 =y
12=y
Finding u after replacing values of x and y
60/20 = (12+u)/12
perform cross product
720=240 +20 u
720-240 =20u
480 =20 u
480/20 =u
24 =u
Finding v after replacing values of x and y
60/20 = (16+v)/16
perform cross product
960=320+20v
960-320 = 20v
640=20v
640/20 =v
32= v

Answer:
x = 31
Step-by-step explanation:
2^x > 4^ 15
Rewrite 4 as 2^2
2^x > 2^2^ 15
We know a^b^c = a^(b*c)
2^x > 2^ (2*15)
2^x > 2^30
Since the bases are the same, the exponents must follow the inequality
x> 30
Answer:
126 tiles
Step-by-step explanation:
The while tiles are 3/4 of a foot (or 9 inches) x 9 in, so their area is 81 sq in. There are 14 blue tiles, so 14 x 81 = 1134 sq inches that need to be covered.
Each tiles is 3 x 3, so its area is 9 sq in. 1134 / 9 = 126 tiles
