says she will 1)give a 10-point bonus and (2) increase everyone's grade by 9% of their score. a. Let x represent the original test scores.Write statements (1) and (2) as the functions f (x) and g(x) respectively.b. Explain the meaning of f(g(x)). Evaluate f(g(75)).c. Explain the meaning of g (f(x)). Evaluate g (f(75)). d. Does g(f(x))=f(g(x)).
Answer:
See explanation
Step-by-step explanation:
A. Let x represent the original test scores.
(1) The teacher will give a 10-point bonus, then the score will be x + 10. Hence,
[tex]f(x)=x+10[/tex]
(2) The teacher will increase everyone's grade by 9% of their score, then the score will be x + 0.09x = 1.09x. Hence,
[tex]g(x)=1.09x[/tex]
B. If [tex]f(x)=x+10[/tex] and [tex]g(x)=1.09x,[/tex] then
[tex]f(g(x))=g(x)+10=1.09x+10[/tex]
Meaning: the teacher increased by 9% the score and then increased the result by 10 points.
[tex]f(g(75))=1.09\cdot 75+10=91.75[/tex]
C. If [tex]f(x)=x+10[/tex] and [tex]g(x)=1.09x,[/tex] then
[tex]g(f(x))=1.09f(x)=1.09(x+10)[/tex]
Meaning: the teacher increased by 10 points the score and then increased the result by 9%.
[tex]g(f(75))=1.09(75+10)=92.65[/tex]
D. [tex]g(f(x))\neq f(g(x))[/tex] because [tex]1.09(x+10)\neq 1.09x+10[/tex]
Karen had a roll of ribbon 48 1/2 metres long. How many pieces of ribbon of length 1 1/5m can she cut from the roll? How many metres of ribbon will be left?
Answer:
40 and 0.5
Step-by-step explanation:
48 and 1/2 metres = 48.5 metres
1 and 1/5 metres = 1.2 metres
Take 48.5 and divide it by 1.2 and you will get 40.41666667...
Since the maximum whole number you can get is 40, you can cut 40 pieces of 1.2 metres of ribbon off.
Remainder = 48.5 - (40 x 1.2) = 0.5 metres left
The number of pieces of ribbon can be cut from roll is 40 and 0.5 m of ribbon left.
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.
We have,
Karen had a roll of ribbon 48 1/2 m long.
= 48.5 m long
and, 1 and 1/5 m = 1.2 m
Now, the number of pieces of ribbon can be cut from roll is
= (48.5) / (1.2)
= 40.416
and, the amount of ribbon left
= 48.5 - (40 x 1.2)
= 0.5 m

What is the equation that represents the line that passes through the point (2,6) and has a slope of -5?
Answer:
y = - 5x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 5, thus
y = - 5x + c ← is the partial equation of the line
To find c substitute (2, 6) into the partial equation
6 = - 10 + c ⇒ c = 6 + 10 = 16
y = - 5x + 16 ← equation of line
Three consecutive integers have a sum of 30. Which equation can be used to find x, the value of the smal
numbers?
o (X+ 1) + (x+2) = 30
X+(x+1)+(x+2) = 30
x(x+ 1)(x+2) = 30
3x(x+ 1)(x+2) = 30
Answer:
It's the second choice.
Step-by-step explanation:
x + (x + 1) + (x + 2) = 30.
Solving for x will give you the smallest digit.
The equation x+(x+1)+(x+2) = 30 is used to find x.
The integers are 9, 10 & 11.
What is the required equation ?
If a, b, c are integers, then the sum of three integers is a+b+c
Let, x be a integer.
Then other two consecutive integers are, x+1 & x+2
Sum of this three integers is x+(x+1)+(x+2)
According to the question,
Sum of this three integers is 30
So, the equation becomes, x+(x+1)+(x+2) = 30
Now, solving, x+x+1+x+2 = 30
⇒ 3x+3 = 30
⇒ 3x = 27
⇒ x = 27/3 = 9
So, (x+1) = 9+1 = 10 & (x+2) = 9+2 = 11
Therefore, the three consecutive integers are 9, 10 & 11

Rearrange to make x the subject
a = 7x/k -r
Help me pls
Final answer:
To make x the subject of the equation a = 7x/k - r, add r to both sides, multiply by k, and then divide by 7, resulting in x = k(a + r)/7.
Explanation:
To rearrange the equation a = 7x/k - r to make x the subject, we need to perform a series of algebraic manipulations. Firstly, we add r to both sides of the equation, giving us a + r = 7x/k. Following this, we multiply both sides by k to get rid of the denominator, which results in k(a + r) = 7x. Finally, we divide both sides by 7 to solve for x, which gives us x = k(a + r)/7. This rearrangement shows x as the subject of the original equation.

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last
skater. Then, they try to decide whether or not Oliver should be the first skater in the race.
Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?
A = {MOPN, PMON}
A = {OPMN, OMPN)
A = {MOPN,MPON, OPMN, POMN)
A = {MOPN. MPON, PMON, POMN)
Answer:
A = {MOPN, MPON, PMON, POMN}
Step-by-step explanation:
Everyone has already agreed that Naim would be the last skater, so we have to make sure that the result has 'N' in each last place. As we can see, they all have this.
Now, we also have to make sure Oliver not first, because although they're trying to decide, the problem asks for the complement in which "Oliver is the first skater in the race."
A complement is all the values that are NOT in the set, so it cannot be A = {OPMN, OMPN) or A = {MOPN,MPON, OPMN, POMN), because they both have at least one case where 'O' is first.
A complement is ALL other values of the set, so it cannot be A = {MOPN, PMON}, because that set only shows two possible values.
Therefore, A = {MOPN, MPON, PMON, POMN} is your answer.
Answer:A=OPMN,OMPN
Step-by-step explanation:
we know oliver is first in the race and naim is last so the other racers are in between

How much wrapping paper will Xan need?
592 square cm
614 square cm
724 square cm
808 square cm
Final answer:
To find the wrapping paper needed for a box with given dimensions and one largest face uncovered, calculate the total surface area, subtract the area of the largest face, resulting in 592 square cm of wrapping paper required.
Explanation:
The question concerns calculating the amount of wrapping paper required to cover a box while leaving one of the largest faces uncovered. Given the dimensions of the box are 12 cm, 10 cm, and 11 cm, we can calculate the surface area of each face and sum them up, excluding one of the largest face, which is one with dimensions 12 cm x 11 cm.
First, calculate the surface area of all the faces: 2(12cm x 10cm) + 2(12cm x 11cm) + 2(10cm x 11cm) = 240cm² + 264cm² + 220cm² = 724cm².Next, subtract the area of the largest face (which will not be covered): 12cm x 11cm = 132cm².Finally, subtract this area from the total surface area calculated: 724cm² - 132cm² = 592cm².Therefore, Xan will need 592 square cm of wrapping paper to cover the box while leaving one of the largest faces uncovered.

Candies
4 red
2 yellow
5 green
1 purple
- Taina doesn't like red candies.
4/4+2+5+1 = 4/12
4/12 is the probability Taina will get a red candy, but we're looking for the opposite.

The sum of four consecutive integers is 342. What is the third term in the sequence
Answer:
x + x + 1 + x + 2 + x + 3 = 4x + 6 = 342
4x = 336
x = 84
The third term is 84 + 2 = 86.
To find the third term in the sequence, we need to determine the first term and the common difference. By setting up and solving equations, we find that the first term is 84 and the common difference is 1. Therefore, the third term in the sequence is 86.
Explanation:To find the third term in the sequence, we need to determine the first term and the common difference.
Let's assume the first term is 'x' and the common difference is 'd'.
The four consecutive integers can be represented as x, x + d, x + 2d, and x + 3d.
Since the sum of these four integers is 342, we have the equation:
x + (x + d) + (x + 2d) + (x + 3d) = 342
Simplifying this equation, we get:
4x + 6d = 342
Now, we have two variables and one equation, so we need another equation to solve for x and d.
We can use the fact that the integers are consecutive, so the common difference is always 1.
Plugging in the value of d = 1 in the previous equation, we get:
4x + 6(1) = 342
Simplifying further, we get:
4x + 6 = 342
4x = 336
x = 84
Therefore, the third term in the sequence is x + 2d = 84 + 2(1) = 86.
