Answer 1

The examples and solutions to the functions are illustrated below based on the information given.

How to illustrate the functions?

1st example: The cost of a bag of rice is $100 and subsequent bags cost $95. Illustrate. the function to calculate the cost for p bags of rice.

The function will be:

C = 100 + (95 × p)

C = 100 + 95p

2nd example: The cost of a pen is $5. Find the cost of s pens.

The function will be:

C = 5 × p

C = 5p

3rd example: Calculate the total amount for m tickets if each ticket is $20.

The function will be;

C = 20 × m

C = 20m

4th example: Bon bought g mangoes at $2 each and d oranges at $3.40 each. Calculate the total cost.

C = (2 × g) + (3.40 × d)

C = 2g + 3.4d

5th example: The average age of k number of boys is 7. Find their total age.

The function will be:

a = (7 × k)

a = 7k

Answer 2

Question 1: Akira sells lemonade at 50 cents a glass. Let m be the amount of money they make in total for g glasses. Akira only has enough lemonade for 20 glasses.

A) Write a function m(g) to represent the total money (in dollars) they make from lemonade sales.

B) What is the domain of the function? Why?

Answer:

A) m(g) = 0.5g

This is since she makes 0.5 dollars per glass

B) The domain is [tex]0 \leq g \leq 20[/tex] where g is an integer. This is since it's impossible to make less than 0 glasses and they cannot make more than 20.

Question 2: Danyon sells CD's at $20 per CD. He has only 15 CD's left.

A) Write a function m(c) to represent the total money he makes from selling c CD's.

B) What is the domain of the function? Why?

Answer:

A) m(c) = 20c, as he makes 20 dollars per CD.

B) The domain is [tex]0 \leq c \leq 15[/tex] where c is an integer, as he can't make less than 0 CD's, and he has only 15 left.

Question 3: A factory is capable of making 60 units per hour. The factory can only run for 24 hours before cool down, and 150 units have already been made.

A) Write a function u(h) to represent the number of units after h hours.

B) What is the domain of the function? Why?

Answer:

A) u(h) = 60h + 150 as it makes 60 units per hour and 150 are already made.

B) The domain is [tex]0 \leq h \leq 24[/tex] as the factory can't run for negative hours and has to cool down after 24 hours.

Question 4: Alazne sells sunglasses at $7 per pair. She has only 30 left before she needs to re-stock.

A) Write a function m(s) which calculates the amount of money she makes after selling s sunglasses.

B) What is the domain of the function? Why?

Answer:

A) m(s) = 7s, as she gets $7 per pair of sunglasses

B) [tex]0 \leq s \leq 30[/tex] where s is an integer, one cannot have a fraction of a pair and she only has 30. She also cannot sell negative sunglasses.

Question 5: Lincoln works at a burger joint in the summer. He makes $3 from every burger he makes. He already has $22 saved. He cannot make more than 10 burgers a day.

A) Write a function m(b) which calculates how much money he gets after making b burgers.

B) What is an appropriate domain for this function?

Answer:

A) m(b) = 3b + 22, as he already has 22 dollars and makes 3 more for every burger.

B) [tex]0\leq b\leq10[/tex], where b is an integer. This is since he cannot make a fraction of a burger, negative burgers, or more than 10 burgers.

He practiced for 5 1/4 hours during the first week and 5 2/3 hours during the second week.
How much time did Rodrigo spend practicing during the third week? Use the numbers and symbols to select the equation that represents the problem. Then solve the equation. Symbols may be used more than once or not at all.
15 1/3, 5 1/4, 5 2/3, x, =, and +.

The equation that represents the problem is
a. 15 1/3 = x - 5 1/4 - 5 2/3
b. x = 15 1/3 + 5 1/4 + 5 2/3
c. x + 15 1/3 = 5 1/4 + 5 2/3

Decimal =
0.875

Explanation:
The answer that has already been given is perfect in and by itself. I just want to give you some methods for doing these type of questions so that you won't stagger when you see these type of questions in exams (like the SAT).
Whenever you see such questions, remember the following things. These are conversions of English words to Mathematical tools.
What

Any variable like
x

Percent / Percentage / %

Divide by 100

Put an equal to (

) sign
I'll give you an example through a question.
What percent of 200 is 5?
Ans: Replace English words by mathematical tools according to the rules I told you.
x
( What) /100 ( percent)
×
( of) 200
=
( is) 5
In a refined form,
x

×
200
=
5

Calculate x. On calculating, x comes out to be
2.5

So, 2.5 percent of 200 is 5.
Now your question is actually very simple if you follow my rules.
You want 87.5%. By the rules, % means divided by 100. So
87.5
%
=
87.5
100
and now using the same strategy, Ans:
875
1000

Disregard the next section if you know how to convert a decimal to a fraction
Section Starts
First, I'll write the decimal form. Whenever you divide by a number that is in form of 1 followed by
n
number of zeroes. (here 1 is followed by 2 zeroes), you should shift the decimal point to the left side by n places.
In this case, shift decimal point in 87.5 to the left by 2 places. So this becomes 0.875.
This is the answer in decimal point.
Now simultaneously, I'll teach you how to convert a decimal into a fraction.
Here, you see 2 types of "numbers". One to the left side of the decimal point and one to the right side of the decimal point.
Here, left side of decimal point is 0 and right side of decimal point is 875.
Count the number of digits in the number to the right side of the decimal point (Here, the number of digits is 3)
Remove the decimal point and divide the number by a number formed by 1 followed by the "digits" we obtained (i.e. 3).
So, 875/1000. Simplify this, and you get your answer.

The diagram shows two right-angled triangles. PQR and QST are straight lines. It is given that sin x = [tex]\frac{15}{17}[/tex] . Find the value of cos y.

Answers

Step-by-step explanation:

[tex] \sin(x) = \frac{15}{17} = \frac{23 + c}{34} \\ 34 \times 15 = 17(23 + c) \\ 510 = 391 + 17c \\ 17c = 119 \\ c = 7[/tex]

[tex] \sin (y) = \frac{7}{25} \\ y = 16.26 \\ \cos(16.26) = \frac{ \alpha }{25} \\ 0.96 = \frac{ \alpha }{25} \\ \alpha = 24 [/tex]

Answers

Answer: A. The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides.

C. The circumcenter is equidistant fromeach vertex of the triangle.

D. The circumcenter is equidistant from each side of the triangle.

Step-by-step explanation:

The properties of the circumcenter of a triangle from the options given include:

• The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides.

• The circumcenter is equidistant fromeach vertex of the triangle.

• The circumcenter is equidistant from each side of the triangle.

Option B is wrong as the circumcenter of an obtuse triangle is not always outside it. For the circumcenter, there is intersection of all the three lines and it's not important that they should always be outside.

Answers

Answer:

C

Step-by-step explanation:

Because the circle is not shaded in, it doesn't count the number it's on:

So it would be a < or >.

Because this is on a number line and the shaded part goes to the left, it will be < because it points to the left.

The non-shaded circle is on 4, so your answer, x, will be:

x < 4

But the answer choices don't have this, meaning you have to simplify all of them.

The first one is:

x + 9 < 5

x < -4

x - 5 < 9

x < 14

x + 5 < 9

x < 4

x - 9 < 5

x < 14

So it would be C.

Mr. Alvarez makes a walkway of 3 cement slabs.He uses 14 cubic feet of cement to make the walkway.Each square slab has a volume of 4 cubic feet

Answers

Answer:

I suppose that you want to see how we can find the volume of each individual slab with the given information, the procedure is as follows.

The walkway has 3 cement slabs,

He uses a total amount of 14 cubic feet to make the complete walkway.

This means that the 3 cement slabs together have a total volume of 14 ft^3

To find the volume of each slab, we need to find the quotient between the total volume and the total number of slabs, then we get:

Volume of each slab = (14 ft^3)/3 = 4 ft^3

This means that each cement slab has a volume of 4 ft^3.

Answer:

6 ft^3

Television is measured by the diagonal. A 55-inch tv has an actual diagonal length of 54.8 inches. Its height is 27 inch Mr.Schlagers entertainment center is 49 inches wide will the tv fit the entertainment center?

Answers

Answer:

47.68 inches

Step-by-step explanation:

As seen in the diagram attached below we can see that the tv is a rectangle. We are given the diagonal and the height which means we have to find the length. Since the tv diagonal forms a right triangle we can use the Pythagorean theorem to solve for the length. This theorem would be the following.

[tex]a^{2} + b^{2} = c^{2}[/tex]

where a and b are the sides of the triangle and c is the diagonal.

[tex]27^{2} + b^{2} = 54.8^{2}[/tex]

[tex]729 + b^{2} = 3,003.04[/tex]

[tex]b^{2} = 2,274.04[/tex]

[tex]b = 47.68[/tex]

Finally, we can see that the length of the TV is 47.68 inches
