Answer:
a.the car is traveling at the speed of 126 km/h
b.the car will cover 630 km in 5 hours
Step-by-step explanation:
first of all we will convert meter in kilometer and second in hour
1 m = (1/1000) km
1s = (1/3600) h
35m/s = 30m/s *(1/1000)km/m *(3600)s/h
now we will cancel the units
35m/s = 35 *(1/1000)km *(3600)/h
= 0.035 * 3600
= 126km/h
There are 550 students at the green country middle school and 220 of them ride the bus to school. What percent of the students ride the bus?
The fraction
represents the number of students that ride the bus to school out of all the students.
To find what percent of students ride the bus to school, we can turn the fraction
into a percent.
We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 220 and 500 using 20.
220 ÷ 20 = 11
500 ÷ 20 = 25
11 ÷ 25 = 0.44
0.44 × 100 = 44%
Therefore, 44% of the students ride the bus to green country middle school.

Step-by-step explanation:
-14=20y-7x,10y+4=2x i think
B. The equation of this line is x = 3.
E. This graph is not a function because the value x = 3 is assigned to more than one y-value.
