Answer:
D
Step-by-step explanation:
First we need to figure out how many people are going on the field trip
if each class has 27 people going and there are 6 classes, 6*27=162
162 ppl are going. If 3 buses can hold 48 ppl then 3*48=144
3 buses are not enough, if we were to bring in one more bus 4*48=192
there would be enough place for everyone
Answer:
Step-by-step explanation:
(x+2)/2 = 1
x + 2 = 2
x = 0
(y + 8)/2 = 4
y + 8 = 8
y = 0
(0, 0)
Answer:
9b /a^5/2
Step-by-step explanation:
9√(a^-5 b^2)
9 sqrt( a^ -5 b^2)
Rewriting sqrt as ^1/2
9 ( a^ -5 b^2)^1/2
9 ( a^ -5) ^1/2 ( b^2)^1/2
we know that an exponent to an exponent means multiply
9 a^ (-5*1/2) b^(2*1/2)
9 a^-5/2 b^1
9b a^ -5/2
We know that x^-y = 1/x^y
9b /a^5/2
13/90
so there are 90 two digit numbers.
there are a 13 two digit numbers divisible by 7. so there is a 13/90 probability of a two digit number being selected at random that’s divisible by 7
