They need 7 cars for the field trip.
Step-by-step explanation:
The given is,
27 students are going to field trip
4 students in each car
Step:1
Let, T = Total students are going field trip
X = Students in each car
Y = Number of cars need for field trip
Step:2
From given,
T = 27
X = 4
Step:3
Numbers of cars need for field trip,
Y =
Y =
=
Y = 6.75 ( For the car, we need to convert the answer into whole number)
Y = 7 cars
Result:
They need 7 cars for the field trip, If 27 students are going on a field trip 4 students in each car.
Answer:
35°
Step-by-step explanation:
From the sketch made, to obtain B we use the cosine angle formula :
We have 2 so des and an included angle
Cos B = (a² + c² - b²) / 2ac
First we obtain the side c
c² = a² + b² - 2ab CosC
c² = 11.2² + 6.7² - 2(11.7 * 6.7) * cos 72
c = 11.13
Using the value of c
Cos B = (a² + c² - b²) / 2ac
CosB = (11.2² + 11.13² - 6.7²) / (2*11.2*11.13)
Cos B = 204.4269 / 249.312
B = Cos^-1(204.4269 / 249.312)
B = 34.9°
