Cik Ain deposited RM5 000 at a bank with an interest rate of 4% per annum.
(a) Calculate the total savings of Cik Ain after she has saved for 1 year.
Answer: RM 5200
Step-by-step explanation:
Principal = RM5000
Rate = 4%
Time = 1 year
Simple Interest = PRT
= 5000 × 4% × 1
= 5000 × 0.04 × 1
= 200
Now, the total savings will be the addition of the principal and the interest which will be:
= RM 5000 + RM 200
= RM 5200
If 1=3
2=3
3=5

License plates in the tiny country of Venn follow a unique pattern. The first character is one of 41 Egyptian hieroglyphs, the second is one of 39 emojis, and the third character is one of 10 polygons. How many 3 character license plates are available to the people of Venn?
Answer:
12710 license plates
Step-by-step explanation:
Given that :
First character = one of 41 different hieroglyphs
Second character = one of 31 emojis
Third character = one of 10 polygons
A license plate consists of 3 characters
Number of 3-character license plates available :
Number of hieroglyphs * Number of emojis * number of polygons
41 * 31 * 10 = 12710 license plates.

65 traffic cones we’re equally spaced over 5/8 of a mile how many traffic cones are used per mile
Given:
65 traffic cones we’re equally spaced over [tex]\dfrac{5}{8}[/tex] of a mile.
To find:
The number of traffic cones are used per mile.
Solution:
We have,
Number of cones used in [tex]\dfrac{5}{8}[/tex] of a mile = 65
Number of cones used for a mile = [tex]65\times \dfrac{8}{5}[/tex]
= [tex]13\times 8[/tex]
= [tex]104[/tex]
Therefore, 104 traffic cones are used per mile.

A school track is shown.
1000 m
74 m
The straightaway on each side measures 1,000 meters. The curves are semicircles with diameter 74 meters. What
is the distance, in meters, around the entire track? Use the button on your calculator and express your answer to
the nearest hundredth
The distance is
meters
Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track:
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters

Atrice needs to find a container that will hold at least 300 cubic Inches of water. Which of these figures could atrice use
Answer:I think it’s answer B
Step-by-step explanation:because if you measure figure 2 it will be about 451 and you need it to hold about 300 so it can’t be a or c and figure 3 holds about 321 while figure 1 holds about something so I think it’s B
what is the area of these parallelograms? 1. the perimeter is 33
2. the perimeter is 64
Answer:
4.5 + 4.5 + 7.5 + 3 + 9 + 4.5 = 33 is the perimeter of the first shape
The area is (4.5 x 7.5) + (3 x 9) = 60.75
(Cut the figure)
Perimeter of the Second Shape is:
22 + 22 + 10 + 10 = 64
Area is: 22 x 10 = 220
Area of a parallelogram is: L x W
Given the equation of a line y = 5x -16, what is the slope of a line PERPENDICULAR to this line?
Answer:
[tex]-\frac{1}{5}[/tex]
Step-by-step explanation:
Notice that the equation y = 5x - 16 is in slope-intercept form, or [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the number in place of the [tex]m[/tex], or the coefficient of the x-term, represents the slope of that line. So, the slope of the given line is 5.
Slopes that are perpendicular to each other are opposite reciprocals. So, we need to find the opposite reciprocal of 5. To do that, write it as a fraction, making it [tex]\frac{5}{1}[/tex]. Then, switch the sign and flip the numerator and denominator. This means that the opposite reciprocal of 5 is [tex]-\frac{1}{5}[/tex], so [tex]-\frac{1}{5}[/tex] is the perpendicular slope.
Tiana solved the problem below and found that there was no solution. Solve the problem. Do you agree with her answer? Show your work to support your answer either way. -6(x - 4) + 4x = -2x + 18
Note: explain it well enough so I could borrow your answers
Answer:
Step 1: Simplify both sides of the equation.
−6(x−4)+4x=−2x+18
(−6)(x)+(−6)(−4)+4x=−2x+18(Distribute)
−6x+24+4x=−2x+18
(−6x+4x)+(24)=−2x+18(Combine Like Terms)
−2x+24=−2x+18
−2x+24=−2x+18
Step 2: Add 2x to both sides.
−2x+24+2x=−2x+18+2x
24=18
Step 3: Subtract 24 from both sides.
24−24=18−24
0=−6

Why might Razis method not be a good way to estimate the probability? My team won 18 of their last 20 matches, so the probability that they will win their next match is 18/20 = 90%
Answer:
It is a really idealistic way to estimate probability.
It usually works well for random events where there is no restriction like:
"There are N elements in a set, the probability of randomly selecting any element is the same (so there is no restriction) meaning that for every single element, the probability is 1/N.
Now suppose that there are K elements (K < N) with a given characteristic, then the probability of randomly selecting one of the K elements out of the sett with N elements is equal to K times the probability of each element, this is:
P = K*(1/N) = K/N"
Then if a dice has 6 possible outputs, and we want to find the probability of getting a 3 or a 5, we need to find the quotient between the outcomes where we get a 3 or a 5 (2) and the total number of outcomes (6)
P = 2/6
Now let's go to the case in the problem:
We know that out of the last 20 games, your team won 18.
Then yes, your team won (18/20)*100% = 90% of their played games.
Does this mean tath the probability of winning the next game is 90%?
Well no, because this is not a random selection, there are a lot of other things needed to analyze, as the win rate of the other team (suppose that the other team won 14 of their last 20 games, then their win rate is (16/20)*100% = 70%
Does this mean that the probability where our team wins is 90%, and the probability of the enemy team winning is 70%?
Well no, this makes no sense at all, and this is why this method is not a good way to estimate probability in complex cases like this one.

A trapezoid has an area of 18 square miles. The bases are 5 miles and 7 miles. Using these measurements, the height of this trapezoid is how many miles
Answer:
3 miles
Step-by-step explanation:
A trapezoid has an area of 18 square miles. The bases are 5 miles and 7 miles. Using these measurements, the height of this trapezoid is how many miles
Area of a trapezoid = 1/2 (a + b)h
The formula for the height of a trapezoid =
h = 2(A/a + b)
A = 18 square miles
a = 5 miles
b = 7 miles
h = 2(18/5 + 7)
h = 2( 18/12)
h = 2 ( 9/6)
h = 3 miles

After eating at a restaurant, Mr. Jackson's bill before tax is $52.50. The sales tax rate is 8%. Mr. Jackson decides to leave a 20% tip for the waiter. How much will the total bill be, including tax and tip?
Answer:
$67.2
Step-by-step explanation:
8% of $52.50
52.5 × 8/100 = $4.2
20% of $52.50
52.5 × 20/100 = $10.5
total
$52.5 + $4.2 + $10.5 =$67.2
Claire is building a dollhouse where 11 inch on the plans is equivalent to 55 inches on the actual dollhouse. Scale Factor If the house is to be 32.532.5 inches tall, what will the height be on the plans? ___________ inches
Answer:
1 : 5 ;
6.5 inches
Step-by-step explanation:
Given that:
11 inch on plan = 55 in actual
The scale factor here is :
11 : 55
1 : 5 ( 1 inch on plan represents 5 inches the actual house)
If the house is 32.5 inches tall
The height in inches of the house on the plan will be:
Actual Height of house / 5
32.5 / 5 = 6.5 inches
Answer: 6.5
Step-by-step explanation:
Find the measure of ∠h in the figure given below. assume that the lines are parallel.
Answer:
70 - b
Step-by-step explanation:
b= 110 so d = 110 - they are opp. angles
d and e are alternate interior angles which add up to 180
d = 110
e =?
e = 180-110 =70
e and h are equal bc they are opp. angles
e=70 and therefore h=70 as well
