Michaela and Aleah play on the same basketball team. In one game Michaela scored one fifth of the team's points and aleah scored one tenth's of the team's points. Together the scored a total of 42 points. How many points did the team score?

Answers

Together they scored 3/10 of the teams total points (since 1/5 = 2/10). Knowing this you can find what 1/10 of the total points scored was by dividing 42 by 3. That gives you 14, now that you know what 1/10 of the points scored was you can find the total points by completing the fraction and multiplying 14 by 10. This gives a total of 140 points scored by the team

An automatic doughnut machine can produce 1500 doughnuts in 9 hours.
How long would it take the machine to make 300 doughnuts?

Answers

Answer:

1 hr, 48 minutes

Step-by-step explanation:

you can create a proportion:

doughnuts/hours = doughnut/hours (h)

1500/9 = 300/h

cross-multiply to get:

1500h = 2700

h = 27/15

h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60

(x + 3) is a factor of the polynomial x^3 + 2x^2 - 5x + n.
What is the value of n?

Answers

Answer:

n = - 6

Step-by-step explanation:

Given (x + h) is a factor of a polynomial f(x) then f(- h) = 0

Here

f(x) = x³ + 2x² - 5x + n and (x + 3) is a factor then f(- 3) = 0 , that is

f(- 3) = (- 3)³ + 2(- 3)² - 5(- 3) + n = 0 , so

- 27 + 2(9) + 15 + n = 0

- 27 + 18 + 15 + n = 0

6 + n = 0 ( subtract 6 from both sides )

n = - 6

evaluate the function h(x) = |-2x|-9 for the given values of x a) h(4)=. b) h(-5)=. c) h(0) =

Answers

Answer:

h(4) = -1 ; h(-5) = 1 h(0) = -9

Step-by-step explanation:

a) h(x) = |-2x| - 9 Substitute x = 4

h(4) = | -2 · 4| - 9

h(x) = | -8| - 9

h(4) = 8 - 9

h(4) = -1

b) h(x) = |-2x| - 9 Substitute x = -5

h(-5) = |-2 · -5| - 9

h(-5) = |-10| - 9

h(-5) = 10 - 9

h(-5) = 1

c) h(x) = |-2x| - 9 Substitute x = 0

h(0) = |-2 · 0| - 9

h(0) = |0| - 9

h(0) = 0 - 9

h(0) = -9
