What is f(x)+g(x)?
Answers
Answer:
The answer is 13x-7
Step-by-step explanation:
f(x) is x-7, and g(x) is 4x3. 4x3 can also mean 12x , because 4x3 is 4*x*3. So, f(x) can be replaced with x-7, and g(x) can be replaced by 12x. (x-7)+(12x) is 13x-7.

You must show your working
Answers
Answer: 12
Step-by-step explanation:
1200/750=1.6
1.6 X 8 = 12.8
12 number of maximum people she can serve.
What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Amount of Apples = 750 g
and, Svetlana has 1.2 Kg of apples
So, number of people she can serve
= 1200/750 x 8
= 1.6 x 8
= 12.8
= 12 people.
Hence, 12 number of maximum people she can serve.

y=2.3•x+160.7
Answers
Answer:
[tex]x=-32.73\,,\,y=85.43[/tex]
Step-by-step explanation:
Given: [tex]y=3.58x+202.6\,,\,y=2.3x+160.7[/tex]
To find: value of x and y
Solution:
[tex]y=3.58x+202.6\,\,(i)\\y=2.3x+160.7\,\,(ii)[/tex]
From equation (i) and (ii),
[tex]3.58x+202.6=2.3x+160.7\\3.58x-2.3x=160.7-202.6\\1.28x=-41.9\\x=\frac{-41.9}{1.28}=-32.73[/tex]
Put [tex]x=-32.73[/tex] in (i)

The park closes at 2:30 P.M. There is a 15−minute break between each game played at the park, and each game takes the same amount of time as Hamid's soccer game. How many more games can be played before the park closes?
Answers
Complete question:
The park closes at 2:30 P.M. There is a 15−minute break between each game played at the park, and each game takes the same amount of time as Hamid's soccer game. How many more games can be played before the park closes? Hamid's soccer game time is 7:00 to 9:15
Answer:
2 more games can be played before the park closes.
Step-by-step explanation:
Given that Hamid's soccer game time is from 7:00 to 9:15 and there's a 15 minute break between games played, the next game time would be: 9:15 + 15 = 9:30
The time for each game would be calculated as:
stop time - start time = 9:15 - 7:00 = 2:15.
Thus, each game time = 2hrs 15mins
The next game time would be:
9:30 + 2:15 = 11:45
This means the next game would be from 9:30 to 11:45
After this, there would be another game(a second extra game) since the park closes at 2:30PM.
Therefore, the next game time would be:
11:45 + 15 mins break = 12:00
The game duration =
12:00 + 2hrs 15 mins = 14:15 or 2:15PM
Considering the fact that the park closes by 2:30 PM, 2 more games will be played.

Work out value of x.
Give answer correct to 3 significant figures.
Answers
Answer:
The side of the square is 5.971 cm
Step-by-step explanation:
If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of [tex]x[/tex] cm, then it's diagonal have the length of [tex]x\sqrt2[/tex] cm. Using the circle's area we can find the diagonal of the square, as shown below:
[tex]area = \pi*r^2\\56 = pi*r^2\\r^2 = \frac{56}{\pi}\\r = \sqrt{\frac{56}{\pi}}\\r = 4.222[/tex]
Since the diameter of the circle is the same as the diagonal of the square, then:
[tex]x\sqrt{2} = 2*r \\x = \frac{2*r}{\sqrt{2}}\\x = \frac{2*4.222}{\sqrt{2}}\\x = 5.971[/tex]

Anne Deno purchased a house to fix up and use as a rental property. The house sold for $123,400. Anne made a $23,400 down payment and mortgaged the rest. Her annual expenses for mortgage interest, taxes, repairs, insurance, and depreciation totaled $8,750. Anne rented the house for $960 per month. What is the annual net income?
Answers
Answer:
The annual net income is $2770
Step-by-step explanation:
The annual net income on the rental property is the yearly rental minus the yearly annual expenses which consist mortgage interest,taxes, repairs,insurance as well as annual depreciation totaling $8,750
Annual rental =monthly rental* 12 months=$960*12=$ 11,520.00
Annual net income=$ 11,520.00-$8,750.00=$2,770
The annual net income is the gain that accrues to Anne Deno for purchasing the rental property and the subsequent letting to tenants

In a newspaper,it was reported that the number of yearly robberies in springfield in 2011 was 240, and then went up by 5% in 2012.How many robberies were there in springfield in 2012?
Answers
Answer:
There were 252 robberies in 2012.
Step-by-step explanation:
Number of robberies in 2011 = 240
5% Increase =
[tex]5/100*240=12[/tex]
Therefore, new number of robberies in 2012 =
[tex]240+12=252[/tex].
To confirm this figure, we use the formula,
% increase = Increase / Original number * 100
Increase= 12
Original number= 240
Therefore,
12 / 240*100 = 5
This confirms that, indeed, there was a 5% increase in 2012.

Answers
Answer:
C) (negative 1, one-half), (0, 1), (1, 2), (2, 4)
Step-by-step explanation:
The set C could be generated by an exponential function. The main reason is that exponential functions hava a restricted range, it can't have negative numbers or the number zero, because power can only be equal or greater than 1.
Additionally, for all exponentials, a null exponent gives 1 as an answer, so point (0, 1) is always present in an exponential function.
Therefore, the right answer is C.
The set of ordered pairs could be generated by an exponential function is C. (negative 1, one-half), (0, 1), (1, 2), (2, 4)
What is an exponential function?

In mathematics, objects undergo series of transformations. Transformation can be defined as the movement of an object from one particular position to another position
The transformations that an object undergoes are such that the resulting figure created is SIMILAR TO OR THE SAME AS the original figure is referred to as ISOMETRIC TRANSFORMATIONS.
They are:
a) Translation: The movement that occurs in translation of objects is the sliding movement. During translation, an objects is moved from one point to another point without rotating or reflecting the object. This is also known as sliding.
b) Reflection: During reflection, an object is transformed turning it over the line of reflection to another side or position.
c) Rotation: Rotation is the transformation of an object by rotating the object about a fixed point.

It’s starting to get colder at night, so Sam decides to remove the goldfish from the pond in his backyard. He tries to catch the fish with a net; however, even though he can clearly see the fish in the water, he misses it. He infers that he missed because the light is being refracted. What is causing the refraction?
1: The air and the water are different colours.
2: The air and the water have different densities (and media).
3: The water is reflecting the light.
4: The air is reflecting the light.
EXPLAIN YOUR ANSWER
Answers
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. Which would make him see the fish in a spot that its not at. So 2 is the correct answer.
Helen gathered 37 mushrooms in three hours. How many mushrooms did she gather every hour, if she gathered 7 more mushrooms in the second hour than in the first hour, and 6 more in the third hour than in the first hour?
Helen gathered

mushrooms in the second hour and
mushrooms in the third hour.
Answers
Answer:
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Step-by-step explanation:
Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:
37 = x + (x+ 7) + (x + 6)
37 = 3*x + 13
3*x + 13 = 37
3*x = 37 - 13
3*x = 24
x = 24 / 3
x = 8
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Answer:
Helen gathered
8 mushrooms in the first hour,

the least of the four consecutive integers is 7.
Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.
According to the given information, the sum of these four consecutive integers is 34:
x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34
Simplifying the equation:
4 x + 6 = 34
Subtracting 6 from both sides:
4 x = 28
Dividing both sides by 4:
x = 7
The four numbers are 7, 8, 9, 10
