Answer:
124 students
Step-by-step explanation:
let number of boys be 11x and girls be 9x.
A.T.Q 124 more boys than girls
equation=
11x = 9x + 124
11x- 9x = 124
2x = 124
x = 124/2 = 62
boys= 62 * 11 = 682
girls= 62 * 9 = 558
total = 558+682 = 1240 students
600 miles is the total and a rate of 30 mi per 0.3 in
600 divided by 30 = 20 units
each unit is 0.3 inches
20*0.3 = 6
6 inches
The definition of the piece-wise function is:

<h3>What is a piece-wise function?</h3>
A piece-wise function is a function that has different definitions, depending on the input.
In this problem, for inputs between -2 and 2, the function is a line that goes through (-2,-4) and (2,6). The slope is:
m = (6 - (-4))/(2 - (-2)) = 2.5.
The y-intercept is of b = 1, hence the rule is:

For x greater than 2 and less than 6, the function is constant at -3, hence the rule is:
.

Answer:
3 rows/hour
Step-by-step explanation:
It is given that, Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden.
120 minutes = 2 hours
We need to find the unit rate per hour for weeding these rows of his garden. It can be calculated as follows :

So, the rate for weeding these rows of his garden is 3 rows per hour.
6636 has 3 circle so 6636=3
8118 has 4 circle so 8118=4
2212 has 0 circle so 2212=0
8688 has 7 circle 8688=7
5971 has 1 circle 5971=1
