3r^2 if r = 1/6 can someone help me please.
Answer:
Step-by-step explanation:
Answer:
f = 1/18ir^3
Step-by-step explanation:
Let's solve for f.
3r2ifr=1/6
Step 1: Divide both sides by 3ir^3.
3fir3/3ir3 =1/6/3ir3
f=1/18ir3
At a local fitness center, members pay a $10 membership fee and $4 for each aerobics class. Nonmembers pay $6 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the same?
Answer:
5 classes
Step-by-step explanation:
Let x represent the number of aerobics classes
Create an equation that sets the member and nonmember prices equal to each other, then solve for x:
4x + 10 = 6x
10 = 2x
5 = x
So, after 5 aerobics classes, the costs will be the same.

Math PLEASE HELP IM SO CONFUSED IM ATTACHING THE SLIDES!!!!
Answer:
x = 19, TS = 22Step-by-step explanation:
Use ratios to solve for x. Corresponding sides have same ratio.Q1
(x + 5)/30 = (36 - 20)/20(x + 5)/30 = 16/20 = 4/55(x + 5) = 4(30)5x + 25 = 1205x = 95x = 19Q2
(5x - 2)/(3x + 1) = 39/26(5x - 2)/(3x + 1) = 3/22(5x - 2) = 3(3x + 1)10x - 4 = 9x + 310x - 9x = 3 + 4x = 7TS = 3x + 1 = 3(7) + 1 = 22

4) -3x - 2y = -17
9x + 2y = 23
A) (1,7)
B) (10,7)
C) (5, 7) D) (-7, 7)
Answer:
A). (1, 7)
Step-by-step explanation:
-3x – 2y = -17
9x + 2y = 23
____________+
6x = 6
x = 6/6
x = 1
9x + 2y = 23
9(1) + 2y = 23
9 + 2y = 23
2y = 23 - 9
2y = 14
y = 14/2
y = 7
find the value of each variable in the parallelogram
Answer:
1. x = 15°
2. y = 12
Step-by-step explanation:
1. Determination of the value of x.
(5x – 5) + 110 = 180 (Adjacent angles add up to 180)
5x – 5 + 110 = 180
5x + 105 = 180
Collect like terms
5x = 180 – 105
5x = 75
Divide both side by 5
x = 75/5
x = 15°
2. Determination of the value of y.
3y – 4 = 2y + 8 (opposite sides are equal)
3y – 4 = 2y + 8
Collect like terms
3y – 2y = 8 + 4
y = 12

slope (m): ?
coordinates: ?
Answer:
Your slope would be: -5
Step-by-step explanation:
First we need to format it into a linear equation which is: y= mx+b
y+5= (x+3)
and than minus 5 on each side to get:
y=(x+3)-5
than use distributive property to get:
y= -5x+-15
your slope would be:
-5
and than you can get any coordinates from the line if you graph the line on the site "desmos" so just use that site :)

I'm fishing. The probability of catching a fish on each cast of my rod (each attempt) is 0.23. Each attempt is independent. If I made 12 attempts and wanted to find the probability that I caught 2 or fewer fish, is this a geometric or binomial situation
Answer:
This is a binomial situation.
Step-by-step explanation:
For each attempt, there are only two possible outcomes. Either you catch a fish, or you do not. This can mean that either we have a binomial distribution, or a geometric.
However, each attempt is independent, which means that in each attempt, the probability of catching a fish is the same, and that this is a binomial situation.
The probability of catching a fish on each cast of my rod is a binomial distribution.
From the question, we can see that there are two possibilities which are whether you catch a fish or not. This gives two possibilities showing that we have a binomial distribution.
However, each attempt is independent, which means that one attempt does not affect the other. This is therefore a binomial situation.
Hence the probability of catching a fish on each cast of my rod is a binomial distribution.

Your friend needs your help. His parents have told him that it is time for him to start paying for his own cell phone. After completing some research on the internet, you have narrowed down his options. Option 1 charges $0.30 for each cell phone call and $25 for unlimited text messaging. Option 2 charges a flat rate of $40.
Which plan is the best option?
Answer:
For less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.
Step-by-step explanation:
Option 1:
For n calls, the cost is given by:
[tex]C_{1}(n) = 25 + 0.3n[/tex]
Option 2:
The cost is flat of 40, so [tex]C_{2}(n) = 40[/tex]
Which plan is the best option?
Depends on the number of calls, as for a high number, [tex]C_1[/tex] will be higher than [tex]C_2[/tex]. We have to find this number. So
[tex]C_{1}(n) > C_{2}(n)[/tex]
[tex]25 + 0.3n > 40[/tex]
[tex]0.3n > 15[/tex]
[tex]n > \frac{15}{0.3}[/tex]
[tex]n > 50[/tex]
This means that for less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.
help, i need you to find the area
Answer:
98
Step-by-step explanation:
Formula Base * Height
7*14=98
Answer:
77 inches
Step-by-step explanation:
The formula for area of a trapezoid is [tex]\frac{b_{1} + b_{2}}{2} h[/tex]. In this case, first add base 1 (8) + base 2 (14) to get 22. Now divide 22/2 to get 11. Now multiply 11 by the height (7), to get 77 in.

8) x - 5y = -15
x - 2y = -12
Answer:
If solving for X. (didn't know if you were solving for X or Y.
x=2y-12
x=5y-15
Step-by-step explanation:
x-2y=-12
+2y on both sides
x=2y-12
x-5y=-15
+5y on both sides
x=5y-15
Answer:
x = -10
y = 1
Step-by-step explanation:
x - 5y = -15
x - 2y = -12
__________--
-3y = -3
y = -3/-3
y = 1
x - 2y = -12
x - 2(1) = -12
x - 2 = -12
x = -12 + 2
x = -10
