Step-by-step explanation:
In a multiple choice examination of 20 questions, four marks are given for each correct answers and one mark is deducted for each wrong answer. There is no penalty for not attempting a question. a candidate attempts "a" questions and get "c" correct. Write down, and simplify, an expression for the candidate's total mark in terms of "a" and "c".
Step-by-step explanation:
Total no. of questions = 20
Marks given for a correct answer = 4
Marks deducted for a wrong answer = 1
No. of questions attended by the candidate = a
No. of questions the candidate gets correct = c
No. of questions the candidate gets wrong = a - c
Marks obtained for correct answers = 4c
Marks deducted for wrong answers = 1 (a - c)
Total marks scored by the candidate =
Marks obtained for correct answers - Marks deducted for wrong answers
Total marks scored by the candidate = 4c - 1 (a - c)
= 4c - a + c
= 5c - a
Helen spent $7.75 to purchase 23 snack-sized bags of chips c and pretzels p for a club meeting. The following system represents this solution.
{c+p=23
{0.25c+0.5p=7.75
How many of each type of snack did Helen buy?
Answer:
pretzels = 8
chips = 15
Step-by-step explanation:
{ c + p = 23
{ 1/4c + 1/2p = 7.75
Both sides * 4
c + 2p = 31
- c + p = 23
p = 31 - 23 = 8
pretzels = 8
chips = 15
At a grocery store, the price of 3 cans of soup is $6.90. at this rate, how much would 10 cans of soup cost
Answer:
$23
Step-by-step explanation:
At a grocery store 3 cans of soup cost $6.90
3 cans = 6.90
1 can= 6.90/3
1 can = $2.3
Therefore the cost of 10 cans can be calculated as follows
1 can= $2.3
10 cans= 10×2.3
= $23
Hence 10 cans will cost $23

The 8 panes cost $18.80. Unfortunately, breaks 3 more panes while repairing the damage. What is the cost of another 3 panes of glass?
Answer:
Step-by-step explanation:
The cost of another 3 panes of glass would be
Solution:
Given, Number of panes of glass bought = 8
Cost of 8 panes of glass =
Number of broken panes of glass = 3
We have to find the cost of 3 panes of glass
By unitary method, If 8 panes of glass costs , then the cost of one pane of glass will be as follows,
Therefore, for 3 panes of glass it would be
Unitary method:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
Which of the following equations represents the graph shown?
A.)f( x) = - x - 2
B.)f( x) = x + 2
C.)f( x) = - x + 2
Answer:
C
Step-by-step explanation:
Looking at the graph, we can see that the graph crosses the y-axis at y=2.
Hence, our y-intercept should be 2.
Therefore, we can eliminate A.
We also notice that the graph is downwards sloping.
Therefore, our slope is negative.
So, we can eliminate B.
Therefore, our answer must be C.
Answer:
C

There are 28 Year 8 students going on the ski trip, out of the 45 students going. Write this proportion as a percentage. Give your answer correct to 1 decimal place.
Answer:
62.2%
Step-by-step explanation:
We are told in the question that:
The total number of students going = 45 students
The number of year 8 students going for the ski trip = 28 students
The proportion is :
28/45
Converting this proportion to a percentage.
28/45 × 100
= 0.6222222222222222 × 100
62.222222222%
Approximately to 1 decimal place is

Investors buy a studio apartment for $240,000. Of this amount, they have a down payment of $60,000.
a. Their down payment is what percent of the purchase price?
b. What percent of the purchase price would a $12,000 down payment be?
Answer:
A) 4%
B) 20%
Step-by-step explanation:
As, A) we will take 60,000/240000 x 100% so that we can find the percentage.
So the answer = 4%
B) for $12,000, 12, 000/240000 x 100%
Answer = 20%
A) The percentage is 4%
B) The percentage is 20%
Given that,

A savings bond currently made Jamar $2,112.64 worth of interest in 7 years. If the investment gained 5.5% annual simple interest each year, approximately how much was the bond originally bought for?
A.$1381.81
B.$2673.21
c.$4903.23
D.$5487.36
Answer:
D; it was bought for $5,487.36
Step-by-step explanation:
Let the investment amount be $x
We use the formula for simple interest to get the interest
(2112.64-x) = (x * 5.5 * 7)/100
211264-100x = 38.5x
138.5x = 211264
x = 211264/138.5
x = 5,847.36

hy 2.6
Answer:
The value of x = 4 if g(x) = 6
Step-by-step explanation:
Given the function
[tex]g(x) = 3(x - 2)[/tex]
as
[tex]g(x) = 6[/tex]
so putting the value of [tex]g(x) = 6[/tex] in the function
[tex]g(x) = 3(x - 2)[/tex]
[tex]6 = 3(x-2)[/tex]
Switch sides and divide both sides by 3
[tex]\frac{3\left(x-2\right)}{3}=\frac{6}{3}[/tex]
[tex]x-2=2[/tex]
[tex]x=4[/tex]
Therefore, the value of x = 4 if g(x) = 6

The price of pears can be determined by the equation P=0.54n, where P is the price and n is the number of pears. What is the constant of proportionality (unit rate)?
PLEASE NEED THIS ASAP!!!!!!!!!!
Answer:
The constant of proportionality is 0.54
Step-by-step explanation:
Given:
P = 0.54n
Where,
P = price of pears
n = number of pears
What is the constant of proportionality (unit rate)?
The constant of proportionality is 0.54
This means a unit of pears cost $0.54
If the number of pears bought, n = 50
Then,
P = 0.54n
When n = 50
P = 0.54(50)
= 27
P = 27 when n = 50
The correct answer is:
The constant of proportionality is 0.54

Step-by-step explanation:
we see here that angle RPN is 180 degrees. SPM is 90 degrees so
angle RPS + angle SPM + angle MPN = 180 degrees
(4y - 10) + 90 + y = 180
(4y - 10) + y = 90
5y - 10 = 90
5y = 100
y = 20
