Answer:
t < 1/2
Step-by-step explanation:
Isolate the <u>v</u><u>a</u><u>r</u><u>i</u><u>a</u><u>b</u><u>l</u><u>e</u> by dividing each side by <u>f</u><u>a</u><u>c</u><u>t</u><u>o</u><u>r</u><u>s</u> that don't contain the <u>v</u><u>a</u><u>r</u><u>i</u><u>a</u><u>b</u><u>l</u><u>e</u>.
Inequality Form: t < 1/2
Interval Notation: ( -infinity, 1/2)
X + y = 19
10x + 4y = 100
This is a systems of equations.
Isolate x from the first equation:
x = 19 - y
Now, plug it into the second:
10(19 - y) + 4y = 100
190 - 10y + 4y = 100
-6y + 190 = 100
-6y = -90
y = 15
Plug y in and solve for x:
10x + 4(15) = 100
10x + 60 = 100
10x = 40
x = 4
There are four 10-point questions and fifteen 4-point questions.
Answer:
it will take 0.056025 seconds to complete
Step-by-step explanation:
Here, we want to know the amount of time it will take. the computer to sort 15 items.
What to do here is simply substitute the value of 15 for x
Thus, we have
t = 0.007(15)^2 + 0.003(15)
t = 0.011025 + 0.045
t = 0.056025
