Answer:
33
Step-by-step explanation:
Since the ratio is 5:3, there is a difference of 2. Divide 22 with 2 and get 11. Each ratio unit it 11. Multiply 11 with 3 to get 33 girls, and with 5 to get 55 boys
Answer:
y = -x +4
Step-by-step explanation:
The y-intercept of the line is at +4, so the only viable choice is the last choice.
___
Each of the equations is shown in slope-intercept form:
y = mx + b
where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...
y = (some x-term) +4
If you want to spend more brain power on the problem, you can compute the slope of the line as ...
m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1
Now, you know for sure the equation of the line is ...
y = -x +4
Answer: 10
Step-by-step explanation:
Solve the inner fraction first: 1000/10 = 100
You will get sqrt(100) = 10
The integer would be
positive 5
