Slope = (6 - 3)/(-2-2)
= 3/-4
= -3/4
answer
slope = -3/4
Given that the monthly cell phone bill is determined by a fixed monthly fee of $35
for 300 anytime minutes and $.40 for each additional minute used.
Dependent variables can be the result of more than one independent
variable.
Consider your phone bill as presented above. Aside from being
charged for minutes over 300, you are charged $1.25 for each directory
assistance call and $.75 per minute for long distance roaming calls. You
also have to contribute at least $1.50 to the federally required
Universal Service Fund per month and this value may vary on your phone
bill but is not an independent variable.
<span>To write
an equation expressing your monthly cost using the below independent
and dependent variables.
Let x = additional minutes used, then the cost for additional minutes used is given by 0.4x.
Let d = number
of directory assistance calls made, then the cost for directory assisitance is given by 1.25d.
Let r = number of long distance
minutes used, then the cost for long distance minutes is given by 0.75r.
Let u = USF monthly charge.
Let y = total monthly bill, therefore the total monthly bill is given by
y = 0.4x + 1.25d + 0.75r + u</span>
Answer:
Alfred has 250 socks in his collection.
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
Based on the information given to us we can see that out of All his Brown socks he has 20% in the wash and the rest are in his drawer. Meaning 80% of the Brown socks are in his drawer. So we first need to find how many Brown socks are in the wash. We can solve this using the <em><u>Rule of Three </u></em>property as shown in the picture below.
120 drawer ⇒ 80%
x wash ⇒ 20%
Now that we have the amount of Brown socks in the washer we can add that to the amount in the drawer to find the total amount of Brown socks.
So we now know that there are a total of 150 Brown socks. Since the question states that the Brown socks are 60% of the total we can use the <u><em>Rule of Three</em></u> to find the total.
150 Brown ⇒ 60%
T Total ⇒ 100%
Finally, we can see that Alfred has 250 socks in his collection.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for <em>r</em> in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.
