You pay $45 per month for cable TV. Your friend buys a satelliteTV receiver for $99 and pays $36 per month for satellite TV. Your friend claims that the expenses for a year of satellite TV are less than the expenses for cable TV in a year. Write and solve an equation to determine when you and your friend will have paid the same amount for TV services. Is your friend correct? Explain
Answer:
yes
Step-by-step explanation:
Yes, he is correct because he pays $36 a month with the satellite TV receiver he payed $135 that month.\But if we do 36x12=432+99=531and the cable tv cost 45x12=540 so even when we add the satellite TV receiver price on his ours is still more expensive
The required month in which both pay the same amount is 11 months. And our friend is right, satellite tv is less expensive than Cable Tv.
Given that,
You pay $45 per month for cable TV. Your friend buys a satellite tv receiver for $99 and pays $36 per month for satellite TV.
To determine when you and your friend will have paid the same amount for TV services.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
let x be the number of months,
According to the question,
For the cost of cable TV = 45x
For satellite TV = 99 + 36x
Now,
99 + 36x = 45x
99 = 45x - 36x
9x = 99
x = 11
Now cost at 12 months,
Cable = 45 * 12 = 540
satellite = 99 + 36 * 12 = 531
So, satellite tv is less expensive than Cable Tv
Thus, the required month in which both pay the same amount is 11 months. And our friend is right.

A square garden has an area of 100ft^2. What is the perimeter of the garden?
Given:
The area of a square garden = 100 sq. ft
To find:
The perimeter of the garden.
Solution:
Let the side of the square garden be a.
Area of a square = [tex]a^2[/tex]
So, [tex]a^2=100[/tex].
Taking square root on both sides.
[tex]a=\pm \sqrt{100}[/tex]
[tex]a=\pm 10[/tex]
Length of side cannot be negative. So, a=10. It means, side length of the garden is 10 ft.
Perimeter of square = 4a.
Perimeter of square garden is
[tex]4(10)=40[/tex]
Therefore, the perimeter of the square garden is 40 ft.

Gina Needs To Pack 130 Pens, 50 Pencils And 20 Erasers Into Identical Gift Bags So That Each Item Is Equally Distributed Among The Gift Bags. (I) Find The Largest Number Of Gift Bags That Can Be Packed. (Ii) Find The Number Of Each Item In A Gift Bag.
Answer:
Step-by-step explanation:
I think the best way is to split up the erasers before you do anything. That would mean there were 20 gift bags in all
If you did that, then each gift bag would contain 2 pencils with 10 left over.
Further 130 pens would divide up into 6 pens in each gift bag with 10 pens left over.

Answer:
its in order from 2 to 3
Step-by-step explanation:
Items are inspected for flaws by two quality inspectors. Both inspectors inspect every item and the probability that an item has a flaw is 0.1. If a flaw is present,it will be detected by the first inspector with probability 0.92, and by the second inspector with probability 0.7. If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 and by the second inspector with probability 0.8. Assume the inspectors function independently.
(a) If an item has a flaw, what is the probability that it will be found by at least one of the two inspectors?
(b) If an item is passed by the first inspector, what is the probability that it actually has a flaw?
(c) What is the probability that the two inspectors draw different conclusions on the same item?
(d) If an item is passed by both inspectors, what is the probability that it actually has a flaw?
Answer:
a)0.976
b)0.00926
c)0.2402
d)0.35
Step-by-step explanation:
Let [tex]X_i[/tex] be an item passed by inspector i
Let Y be the event that there is a fault in an item
The probability that an item has a flaw is 0.1 i.e. P(Y)=0.1
If a flaw is present ,it will be detected by the first inspector with probability 0.92 i.e.[tex]P(\bar{X_1}|Y)=0.92[/tex]
So, [tex]P(X_1|Y)=1-0.92=0.08[/tex]
If a flaw is present ,it will be detected by the second inspector with probability 0.7 i.e.[tex]P(\bar{X_2}|Y)=0.7[/tex]
So,[tex]P(X_2|Y)=1-0.7=0.3[/tex]
If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 i.e. [tex]P(X_1|\bar{Y}) = 0.95[/tex]
So, [tex]P(\bar{X_1}|\bar{Y}) = 1-0.95=0.05[/tex]
If an item does not have a flaw, it will be passed by the second inspector with probability 0.8 i.e. [tex]P(X_2|\bar{Y}) = 0.8[/tex]
So, [tex]P(\bar{X_2}|\bar{Y}) = 1-0.8=0.2[/tex]
a)P(found by atleast one inspector | It has flaw )=1-P(found by none inspector | It has flow )
P(found by atleast one inspector | It has flaw )=[tex]1-P(X_1|Y) P(X_2|Y)[/tex]
P(found by atleast one inspector | It has flaw )=[tex]1-0.08 \times 0.3[/tex]
P(found by atleast one inspector | It has flaw )=0.976
Hence the probability that it will be found by at least one of the two inspectors if it has flaw is 0.976
b)[tex]P(Y|X_1)=\frac{P(X_1|Y) P(Y)}{P(X_1|Y) P(Y)+P(X_1|\bar{Y}) P(\bar{Y})}[/tex]
[tex]P(Y|X_1)=\frac{0.08 \times 0.1}{0.08 \times 0.1+0.95 \times 0.9}=0.00926[/tex]
C)P( two inspectors draw different conclusions on the same item)=[tex]P(X_1 \cap \bar{X_2} \cap Y)+P(\bar{X_1} \cap X_2 \cap Y)+P(X_1 \cap \bar{X_2} \cap \bar{Y})+P(\bar{X_1} \cap X_2 \cap \bar{Y})[/tex]
P( two inspectors draw different conclusions on the same item)=0.2402
D)
[tex]P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2)}\\P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2 \cap Y)+P(X_1 \cap X_2 \cap \bar{Y})}\\P(Y|(X_1 \cap X_2))=0.35[/tex]

Step-by-step explanation:
given that San weighs out 78 ounces
given that the margin is 2.5 ounces.
and also given that the formula is
|c-78|=2.5
maximum
the maximum ounces is= 78+2.5
the maximum ounces is= 80.5 ounces
minimum
the maximum ounces is= 78-2.5
the maximum ounces is= 76.5 ounces

When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6?
The ratios are equivalent to 5:6.
The ratios are equivalent to 6:5.
The ratios are greater than 5:6, as the factors become greater.
The ratios are greater than 6:5, as the factors become greater.
Answer:
Aren't they equivalent to 5:6?
Step-by-step explanation:
Your situation models to 5x:6x, and no matter what you put as x, it will amount to the ratio of 5:6. It's basically a big fraction, with 5/6 as the simplfication.
Answer:
Step-by-step explanation:
The easiest way to start this is just to multiply the 5 and the 6 by the same thing and see what happens.
Randomly, I will choose 7 because I think today is the 7th.
5*7
====
6*7
35
===
42
I know this is going to seem ridiculous but I'm not going to divide 35/42 by 7.
35 divide by 7 = 5
42 divide by 7 = 6
Just what you started with.
Now a little less obvious, suppose we multiply top and bottom of the ratio by a. a can be anything like (say) the 5th root of 3233
5* a
====
6 * a
Divide the top and bottom by a.
5a divided by a = 5
=======
6a divided by a = 6
So what's the answer? If you've read through this, you'll know that nothing changes.
The answer is the first one.
-3x-9=27x-6(5x-9) plz help
Answer:
No Solution
Step-by-step explanation:
Use the distributive property, to take out the contents from the parentheses
-6 * 5x = -30x
-6 * -9 = 54
-30x + 54
27x -30x + 54
Combine the terms that have the same variable
27x + -30x = -3x
-3x + 54
-3x - 9 = -3x + 54
Combine terms that have the same variable
-3x + 3x = 0
-9 = 54
-9 does not equal 54, therefore there is no solution

The cost of the hiking trip is 2/3 of the cost of last years trip this year trip cost $32 write and solve an equation to find the cost of last years trip
Answer:
(32/2)*3=48
Step-by-step explanation:
In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.
Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.
If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
