Answer:
Mean (Average) = -23.5
Median = -26.5
Mode = -28
Range = 52
Step-by-step explanation:
Mean is found when adding all numbers and dividing the outcome by the number of numbers, so -
-11 + -28 + -17 + -25 + -28 + -39 + 6 + -46 = -188
-188 ÷ 8 = -23.5
Median is found in the center, and can be found ordered from least to greatest -
-46, -39, -28, -28, -25, -17, -11, 6
last 2 remaining number would be -28 and -25, add those and divide by 2 which gives you -26.5.
The Median would be -26.5
Mode is the number that has repeated itself the most.
-28 repeated itself the most.
The Range is found when the least number is subtracted by the greatest number so -
6 - (-46) = 52

Step-by-step explanation:
1.
Imagine this as a triangle like shown in pic attached, then use tan to find 'x', the distance between the base of the tower and the fire:
tanA=opposite/adjacent
tan25=x/1000
x=100tan25
x=466.3ft
2.
Imagine this as a triangle like shown in pic attached, then use sine to find 'x', the kite's vertical height above the boy's hand:
sinA=opposite/hypotenuse
sin12=x/50
x=50sin12
x=10.4m
The kite's height off the ground is this plus the height of the boy's hand from the ground: 10.4+1.7=12.1m

The value of the first number is
Answer:
1st number = 17
2nd number = 23
Step-by-step explanation:
x = 1st number
y = 2nd number
x = y - 6
6x = 10 + 4y
substitution method:
6(y - 6) = 10 + 4y
6y - 36 = 10 + 4y
2y - 36 = 10
2y = 46
y = 23
find 'x':
x = 23 - 6
x = 17

Answer:
(i) 22.5
(ii) 7.2
Step-by-step explanation:
(i)
AB:PQ = 2:5 = 1:2.5
So PQ is 2.5 times longer than AB.
PQ=2.5AB=(2.5)9=22.5
(ii):
Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:
QR=2.5BC
BC=QR/2.5=18/2.5=7.2

What is the surface area of the figure? 408ft^2 458ft^2 545ft^2 720ft^2
9514 1404 393
Answer:
(b) 458 ft²
Step-by-step explanation:
The total area is the sum of the L-shaped front and back areas and the areas of the 6 rectangular faces.
The front L-shaped area can be considered to be a 12 ft × 12 ft square with a 5 ft × 7 ft rectangle cut from the upper left corner. Its area is then ...
(12 ft)(12 ft) -(5 ft)(7 ft) = (144 -35) ft² = 109 ft² . . . . front area
__
The sum of the areas of the rectangular faces is the product of the width of the figure (5 ft) and the perimeter of the L-shaped face. That perimeter is the sum of the edge lengths. Starting from the lower-left corner and working clockwise, we find the perimeter to be ...
7 ft + 7 ft + 5 ft + 5 ft + 12 ft + 12 ft = 48 ft
Then the sum of rectangular face areas is ...
(48 ft)(5 ft) = 240 ft² . . . . rectangular face area
The total surface area is then ...
2×front area + rectangular face area
= 2×109 ft² +240 ft² = 458 ft² . . . . total surface area
convert the following recurring decimal to a rational number 0,72
Answer:
The repeating decimal 0. 72 can be written as a ratio of two integers with numerator 8 and denominator 11 as the numerator and denominator, respectively. As a result, it is a logical number (named after ratio). If a number's decimal representation repeats or terminates, it may be seen to be rational.
Step-by-step explanation:
0.72 equals 8 /11
as a fraction.
How do you turn 0.72 repeating into a fraction?
Detailed Answer:
Step 1: To convert 0.72 repeating into a fraction, begin writing this simple equation:
n = 0.72 (equation 1)
Step 2: Notice that there are 2 digits in the repeating block (72), so multiply both sides by 1 followed by 2 zeros, i.e., by 100.
100 × n = 72.72 (equation 2)
Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.
100 × n = 72.72
1 × n = 0.72
99 × n = 72
72 /99
could be the answer, but it still can be put in the simplest form, i.e., reduced.
To simplify this fraction, divide the numerator and denominator by 9 (the GCF - greatest common factor).
n = 72
99 = 72 ÷ 9
99 ÷ 9 = 8 11 .
So, 0.72 = 8 /11
as the lowest possible fraction.
