An art class has 33 students. The ratio of boys to girls is 5:6. How many girls are in this
lesya692 [45]

Answer:

boys = 15

girls = 18

---

Step-by-step explanation:

g/b = 6/5

g = (6/5)b

g + b = 33

---

g + b = 33

(6/5)b + b = 33

(6/5)b + (5/5)b = 33

(11/5)b = 33

---

b = 33(5/11)

Find the average rate of change for problems 1-3: X. X^2+7 2. 11 3. 16 4. 23 5. 32 6. 43 1) what is the average rate of change b
miv72 [106K]

Answer:

(1)7 (2)9 (3)6

Step-by-step explanation:

\left|\begin{array}{c|cc}X&f(X)=X^2+7\\--&-----\\2&11\\3&16\\4&23\\5&32\\6&43\end{array}\right|

(1)The average rate of change between x=2 and x=5

\dfrac{dy}{dx} =\dfrac{f(5)-f(2)}{5-2} =\dfrac{32-11}{3} =\dfrac{21}{3} =7

(2)The average rate of change between x=3 and x=6

\dfrac{dy}{dx} =\dfrac{f(6)-f(3)}{6-3} =\dfrac{43-16}{3} =\dfrac{27}{3} =9

(3)The average rate of change between x=2 and x=4

\dfrac{dy}{dx} =\dfrac{f(4)-f(2)}{4-2} =\dfrac{23-11}{2} =\dfrac{12}{2} =6
