Answer:
A: Neither is a better deal, they cost the same person cubic foot
------
B: The large truck's volume is 2.3 times greater than the small truck's
C: At least: three vans, or two small trucks, or one large truck
Step-by-step explanation:
V=Lhw R=$/ft³
Vv=10.5(6)(6)
Vv=378 ft³
Rv=94.5/378
Rv= 25¢ per ft³
Vs=12(8)6.75
Vs=648 ft³
Rs=162/648
Rs=25¢ per ft³
------
Vl=20(8.75)8.5
Vl=1487.5 ft³
1487.5=648n
2.295=n

Christy c = 90 min
kids k = 120 min
total time t = ?
I would do : 90+120 = 210 then divide that by 2 which equals 105 min
15)
20/8 = x / 6
x = 20 * 6 / 8
x = 15
16)
18/54 = (x+4)/75
1/3 = (x+4) / 75
3(x+4) = 75
3x + 12 = 75
3x = 63
x = 21
SF = 54/18
SF = 3
17)
complement angles sum = 90
90 /18 = 5
so
5 x 11 = 55
5 x 7 = 35
smaller angle = 35 degrees
18)
ratio 4:5:9
4+5+9 = 18
sum of interior angles of a triangle = 180
180 / 18 = 10
largest angle = 10 x 9 = 90
answer
largest angle = 90 degrees
Answer:
0
Step-by-step explanation:
((3/5 ^0)^-2)
3/5^0=0
0^-2= 0
