Angie and kenny play online video games. Angie biys 1 software package and 4 months of game play. Kenny buys 1 software package and 1 month of game play. Each software costs $35. If their total cost is $130 what is thr cost of one month of game play
Answer:
1 month of game play will cost $12
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of one month of game play.
From the question, we know the following;
Angie bought 1 software package and 4 months of game play
while
Kenny bought 1 software package and 1 month of game play.
The total packages and months bought will be;
2 packages and 5 months of game play
From the question, we are told that 1 month of game play is $35, so 2 months of game play will be 2 * $35 = $70
So the amount remaining for the 5 months will be; $130 - $70 = $60
So if 5 months cost $60, it means one month will be $60/5 = $12

Step-by-step explanation:
Diameter of Earth is 12756000m. In 1996, a new planet was discovered whose diameter is 5/86 of the diameter of Earth. Find the diameter of this planet in km.
Answer:
741.63km
Step-by-step explanation:
From the above question, we know the following things:
Diameter of the Earth = 12756000m
Diameter of the new planet = 5/86 of the Diameter of the Earth
Diameter of the new planet =
5/86 × 12756000m
= 741627.90698m
The diameter of the new planet = 741627.90698m
We were asked to find the diameter of the new planet in km, hence we convert from meters to kilometers
1m = 0.001km
741627.90698m =
741627.90698 × 0.001km
= 741.62790698km
Approximately = 741.63km
Therefore, the diameter of the new planet = 741.63km
1. Point P is between points F and G. The distance between points F and P
is 1/4 of FG. What is the coordinate of point P?
Answer:
Point P is in between points F and G.
Now, here we do not have the actual locations of F and G, so i will answer this in a general way.
Suppose that F is located at 0 and G is located at some value A.
Then the distance FG = A - 0 = A.
Now, the distance between F and P is:
Distance = (1/4)*FG = A/4
Then the location of P is equal to the location of F plus A/4
P = 0 + A/4
Now, writing this in a more general way:
P = F + FG/4
An air conditioner repair service charges $60 for a service call plus $30 per hour for labor, from 1 to 6 hours. The total
amount charged to the customer m, for any number of service hours, h can be represented by the function
m=30h+60 where h is an integer. What is the range?
Answer:
[90, 240]
Step-by-step explanation:
Here, the range can be found by considering the values of m at the extremes of the domain.
for 1 hour, m = 30(1) +60 = 90
for 6 hours, m = 30(6) +60 = 240
The range of m is [90, 240].

If you vertically compress the absolute value patent function, f(x)=|x|, by a factor of 5, what is the equation of the new function?
A vertical compression implies a reduction in the y-values of the absolute value function. Therefore, the term that we use to accomplish the reduction cannot be attached to the x in the equation. If so, we would end up with a horizontal stretch, not a vertical compression.
Compression implies a reduction, or dividing, so our term will be 1/5. This should be placed outside of the absolute value bars so that the compression affects only the y-values.
Correct answer: B. g(x) = 1/5|x|

Find the product of (x + (3+5i))^2
Answer:
x^2 +6x +10xi -16 +30i
Step-by-step explanation:
(x + (3+5i))^2
Rewriting as
(x + (3+5i)) (x + (3+5i))
Let 3+5i = m
(x + m) (x + m)
FOILing
x^2 + xm+xm+m^2
x^2 +2xm + m^2
Replacing m with 3+5i
x^2 +2x (3+5i) +(3+5i)^2
Distribute
x^2 +6x +10xi +(3+5i)^2
Now FOIL (3+5i)^2
( 3+5i) ( 3+5i)
3*3+ 3*5i + 3*5i+ 25i^2
= 9 +15i+15i +25(-1)
9+30i -25
-16 +30 i
Replacing that in the equation
x^2 +6x +10xi -16 +30i
Answer:
x² + 6x + 10xi -16 + 30i
Step-by-step explanation:
(x + (3 + 5i) )²
use the binomial theorem:
(a + b)² = a² + 2ab + b² to expand (x + (3 + 5i) )²
substitute the values,
x² + (6 + 10i)x + (-16 + 30i)
therefore
x² + 6x + 10xi -16 + 30i

A deli has a special one-day event to celebrate its anniversary. On the day of the event, every eighth customer receives a free drink. Every twenty-eighth customer receives a free sandwich. If 200 customers show up for the event, how many of the customers will receive both a free drink and a free sandwich?
Answer:
the number of common customers are 8 in number
Answer: The answer is just 3 people will get BOTH the free drink and free sandwich.
Step-by-step explanation:
Every 8th = 1 free drink
Every 28th = 1 free sandwich
200 costumers showed
Add 28 to 28 until you reach the closest to 200 so: 28,56,84,112,140,168,196
Then add 8 to 8 until 200, every number that match the 28th sequence is 1 costumer that receives 1 drink and 1 sandwich
The match numbers are 56,112,168

A. Beef uses significantly more land than plants to produce 100 grams of protein
B. Meat production is more efficient than farming protein from fish and prawns
C. Lamb and mutton produce more protein per square meters than pig meat and poultry
D. Nuts and grains produce less protein per square meter than milk and cheese
Answer:
the answer is correct 2 one
Answer:
A. Beef uses significantly more land than plants to produce 100 grams of protein
Step-by-step explanation:
Let's examine each answer choice.
A. Beef uses significantly more land than plants to produce 100 grams of protein
This is true. Beef uses 163.6 square meters of land, while peas only use 3.4 square meters.
B. Meat production is more efficient than farming protein from fish and prawns
This is not true. Meat production is less efficient, because it uses more land than fish and prawns.
C. Lamb and mutton produce more protein per square meters than pig meat and poultry
This is false. Lamb produces less protein per square meter, because it takes 184.8 square meters to produce 100 grams of protein, while pig meat only takes 10.7 square meters to make the same amount.
D. Nuts and grains produce less protein per square meter than milk and cheese
This is false. Milk and cheese require more square meters per 100 grams of protein/ Therefore they produce less protein per square meter, not the nuts and grains.
So, the best answer choice is A. Beef uses significantly more land than plants to produce 100 grams of protein

two times the sum of a number and 9 is half the number
Write an equation to represent the phrase
Answer:
Equation:
2(a+9) = a/2
Solve:
The umber is:
-12
Step-by-step explanation:
Equation:
2(a+9) = a/2
Solve:
2*a + 2*9 = a/2
2a + 18 = a/2
2a - a/2 = -18
4a/2 - a/2 = -18
3a/2 = -18
a = -18*2/3
a = -12
Check:
2(-12+9) = -12/2
2(-3) = -12/2 = -6
The Equation for the phrase is 2(x + 9) = x/2.
What is the equation?A mathematical statement with two algebraic expressions on either side of an "equal to (=)" sign is called an equation. It demonstrates the equality of the relationship between the expression written on the left and right sides. If there is no "equal to" symbol in the statement of any mathematical equation, it is not one. It will be taken into account as a phrase.
Given a phrase two times the sum of a number and 9 is half the number,
the first part of the phrase says two times the number and 9,
let the number be x, the equation will be
2(x + 9)
the second part of the phrase is half the number
x/2
final equation is
2(x + 9) = x/2
Therefore, the equation is 2(x + 9) = x/2.

Given the equation p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t, which equation is solved for t?
Answer:
[tex]t=\dfrac{p}{(s_1-s_2)}[/tex]
Step-by-step explanation:
It is given that, p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t. It can also written as :
[tex]p=s_1t-s_2t[/tex]
We need to solve the above equation for t.
Taking t common on RHS of the equation :
[tex]p=(s_1-s_2)t[/tex]
Now dividing both sides by [tex](s_1-s_2)[/tex], so,
[tex]\dfrac{p}{(s_1-s_2)}=\dfrac{(s_1-s_2)}{(s_1-s_2)}t\\\\t=\dfrac{p}{(s_1-s_2)}[/tex]
