Hey guys! I would be thankful if anyone could help me answer this question. A can manufacturing company needs to purchase labels for the cans they produce. They are planning to produce 200,000 cans that will have a height of 20cm and a radius of 5 cm. If the labels cover the entire curved surface of each can, how many square metres of material will be required to label all the cans?
Answers
h=20 cm = 0.2m and r=5cm = 0.05m
The cans are cylinders and we only need the rectangular shape, which is equal to the height x the circumference of the circle (2r(pi)), which you'll have to multiply by 200,000 for the number of cans necessary
your equation is therefore:
A=200,000h(2pi(r))
A=200,000(0.2)(2)(0.05)(pi)
A=4000pi m^2
r = 5cm, h= 20cm
Surface area for one can = 2πrh = 2*π*5*20 = 200π = 200* 3.14
Surface area ≈ 628 cm²
For the 200, 000 cans, Total area = 200 000 * 628 = 125 600 000 cm²
But 1 000 000 cm² = 1m²
125 600 000 cm² = 125 600 000 / 1 000 000 = 125.6 m²
Total surface area ≈ 125.6 m²

Answer: x = - 10
Step-by-step explanation:
a) Linear Pair: 138 + ∠a = 180° --> ∠a = 42°
b) Triangle Sum Theorem: ∠a + 2∠b = 180° --> ∠b = 69°
c) Vertical Angles Theorem: ∠b = ∠c --> ∠c = 69°
d) Congruent sides implies congruent angles: ∠c = ∠d --> ∠d = 69°
∠2) Triangle Sum Theorem: ∠c + ∠d + ∠2 = 180°
69° + 69° + ∠2 = 180°
∠2 = 42
x) m∠2 = 42
x + 52 = 42

Given:
The coordinates of the point A and B are (-5,-1) and (4,1)
The point P on the directed line segment from A to B such that P is One-fourth the length of the line segment from A to B.
Thus, we have;
and
We need to determine the coordinates of the point P(x,y)
x - coordinates of the point P:
The x - coordinates of the point P can be determined using the formula,
Substituting the values, we get;
Thus, the x - coordinate of the point P is
y - coordinate of the point P:
The y - coordinate of the point P can be determined using the formula,
Substituting the values, we get;
Thus, the y - coordinate of the point P is
Therefore, the coordinates of the point P is
Hence, Option C is the correct answer.

Answers
Answer:
T = $1.50C + $1.00L
Step-by-step explanation:
Chocolate chip cookies - $1.50/dozen
C: # of dozens of chocolate chip cookies
↓
$1.50C
Lemon Frosteds - $1.00/dozen
L: # of dozens of lemon frosteds
↓
$1.00L
T(total) = $1.50C + $1.00L

Standard Deviation: _________a1
Answers
100 students:
pass = + 4
fail =+ 0
90 students passed: 90 * 4 = 360
10 students failed: 10 * 0 = 0
mean: 360 / 100 = 36
standard deviation:
36 - 4 = 32 ⇒ 32² = 1,024 * 90 = 92,160
36 - 0 = 36 ⇒ 36² = 1,296 * 10 = 12,960
92,160 + 12,960 = 105,120
105,120 / 100 = 1,051.20 ⇒ variance
Standard deviation = √1,051.20 = 32.42
