Answer:
deal with the rectangle first A = l X w
4 X 12 = 48 squared cm
semi circle
Area of a circle πr^2
12/2 = 6, radius = 6
π6^2 = 113.097335
113.097335/2 = 56.5486677
56.5 + 48 = 104.5 squared cm
Show how to rewrite 1/5 with the denominator 10
The denominator is the bottom number.
To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10
Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.
1 x 2 = 2
So 1/5 = 2/10
The answer is 2/10

class A has 11 pupils and class B has 14 pupils. Both classes sit the same maths test. the mean score for class A is 32. The mean score for class B is 38. What is the mean score(rounded to 2DP) in the maths test across both classes?
Answer:
35.36
Step-by-step explanation:
For Class A
Class A has 11 pupils
The mean score for Class A is 32.
The total score of the students =
Mean score × Number of pupils
= 32 × 11
= 352
For Class B
Class B has 14 pupils. The mean score for class B is 38.
The total score of the students =
Mean score × Number of pupils
= 38 × 14
= 532
Total number of pupils for both classes = (11 + 14)pupils
= 25 pupils
Total score for both class = 532 + 352
= 884
The mean score(rounded to 2DP) in the maths test across both classes is calculated as:
Total score of both classes÷ Total number of pupils
884 ÷ 25
35.36

What is the expression in factored form?
2x^2+16x+24
Is it (x-2)*(x-6) or 2(x-2)*(x-6)?
Answer:
( 2x +4) ( x+6)
Step-by-step explanation:
Explanation:-
Given expression 2 x² + 16 x + 24
The factors of 48 = 12 × 4
⇒ 2 x² + 16 x + 24
⇒ 2 x² + 12 x + 4x + 24
⇒ 2 x ( x +6 ) + 4( x +6)
⇒ ( 2x +4) ( x+6)

You and your friend are having a friendly competition about the scores on your math quizzes. Both of your scores for the first five quizzes are given below:
Your quiz scores: 18, 16, 19, 15, 17
Friend’s quiz scores: 20, 20, 13, 12, 17
a. Find the mean, median, and mode of both sets of data.
b. Which person – you or your friend – has the higher mean?
World Populations:
The populations (in millions) in 2000 on each of the six inhabited continents were:
803, 487, 348, 368, 730, and 31
a. What is the range of the populations?
b. Find the mean, median, and mode(s) of the populations.
Tomato Plants:
The heights (in inches) of eight tomato plants are:
36, 45, 52, 40, 38, 41, 50, and 48
a. What is the range of the tomato plant heights?
b. Find the mean, median, and mode(s) of the tomato plant heights.
Answer:
:)
Step-by-step explanation:
quiz scores:
a. arrange them all from least to greatest to figure out the median first
your quiz: 15, 16, 17, 18, 19 middle # = 17 median = 17
friend's quiz: 12, 13, 17, 20, 20 middle # = 17 median = 17
now for mean add all of your quiz scores up and divide by how many #s
15 + 16 + 17 + 18 + 19 = 85 / 5 = 17 mean = 17
now your friend's:
12 + 13 + 17 + 20 + 20 = 82 / 5 = 16.4 mean = 16.4
mode is which number is used the most
your mode = you don't have a mode your friend's mode = 20
b. you have a higher mean than your friend
world populations:
a. range is to subtract the smallest number from the largest
803 - 31 = 772
b. mean is adding it all up and dividing by how many numbers there are:
803 + 487 + 348 + 368 + 730 + 31 = 2767 / 6 = 461.17
median is arranging them in order and finding the middle #
31, 348, 368, 487, 730, 803
368 + 487 = 855 / 2 = 427.5
mean = 461.17
median = 427.5
mode = no mode
tomato plants:
a. range is subtracting the smallest from the largest
52 - 36 = 16
b. mean is adding all the #s and dividing by how many #s there are:
36 + 45 + 52 + 40 + 38 +41 + 50 + 48 = 350 / 8 = 43.75
median is the middle from least to greatest
36, 38, 40, 41, 45, 48, 50, 52
41 + 45 = 86 / 2 = 43
mean = 43.75
median = 43
mode = no mode

Terms/CoefficientsStep-by-step explanation:
Step 1: Define
3.6y = 1.6y + 24
Step 2: Solve for y
[Subtraction Property of Equality] Subtract 1.6y on both sides: 2y = 24[Division Property of Equality] Divide 2 on both sides: y = 12Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: 3.6(12) = 1.6(12) + 24Multiply: 43.2 = 19.2 + 24Add: 43.2 = 43.2Here we have 43.2 does indeed equal 43.2.
∴ y = 12 is the solution to the equation.

Mr. Jones has 550 goats, which is 10% more than Mr. King has. How many more goats does Mr. Jones have than Mr. King?
Answer:
55
Step-by-step explanation:
Number of Jone's goats = 550
Let Number of King's goat = x
Jone's goat is 10% more than King's ;
Thus, number King's goat would be ;
x = 550 - (10% of 550)
x = 550 - 55
x = 495
x = Mr. King's goat
Hence, Jones goat is :
550 - 495 = 55 more than Mr King's goat.
Mr King has 55 goats
Number of goats owned by Mr Jones is 550
let y represent the goats owned by Mr King
y= 550-(10% × 550)
= 550- (0.1×550)
= 550 - 55
= 495
= 550-495
= 55
Hence Mr King has 55 goats than Mr Jones

What is the surface area? how did you find it(filled-in formula)?
Answer: 1719.22 mi squared
Step-by-step explanation:
you have to find the height first.
you only have r and hypotenuse
so
a^2 + b^2 = c^2
13^2 + b^2 = 29.1^2
169 + b^2 = 846.81
b^2 = 846.81 - 169
b^2 = 677.81
b = 26.03
height = 26.03
surface area formula :

π(13) [13 + _/26.03^2 + 13^2]

Answer:
$29.14
$86.68
Step-by-step explanation:
$30 before tax
Discount: 20%
100% - 20% = 80% = 0.8
0.8 * $30 = $24 after discount
Tax: 6.4%
100% + 6.4% = 106.4% = 1.064
1.604 * $24 = 25.54 after tax and discount
Tip: 15% = 0.15
0.15 * $24 = $3.60
Total = $25.54 + $3.60 = $29.14
$75 before tax
10% discount
100% - 10% = 90%
90% of $75 = 0.9 * $75 = $67.50 after discount
Tax: 7%
100% + 7% = 107% = 1.07
1.07 * $67.5 = $72.23 after discount and tax
Tip: 20% = 0.2
0.2 * $67.50 = $13.50
Total = $72.23 + $13.50 = $85.73

(the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter os the room?
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.

B. 363 = 27 +39 + S
C. (36 + 3) + S +27 +39
D. (27 +39 + S) + 3 = 36
Answer:D
Step-by-step explanation:
Answer: none of them are right...
Step-by-step explanation:
(27 + 39 + S)/3 = 36
