Find the probability of rolling divisors of 24
Answer:
5/6 is the probability
Step-by-step explanation:
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so
correct 33.246 to 2 significant figures
The value of number after 2 significant figures is, 33
What is rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.
Given that;
Correct the number 33.246 to 2 significant figures.
Now, we can check the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.
Thus, The value of number after 2 significant figures is,
⇒ 33

0.12 cubic meters of silver which she needs to make into 9.9e4 coins of thickness 2 mm. If she uses all of the silver, what is the diameter in centimeters of each coin
Answer:
The diameter of each coin is approximately 2.778 centimeters.
Step-by-step explanation:
According to the statement, 0.12 cubic meters ([tex]1.20\times 10^{8}\,mm^{3}[/tex]) were used to produce 99000 coins. First, we calculate the volume of each coin ([tex]V_{c}[/tex]), measured in cubic meters, by dividing the total volume by the number of coins. That is:
[tex]V_{c} = \frac{1.20\times 10^{8}\,mm^{3}}{99000}[/tex]
[tex]V_{c} =1212.121\,mm^{3}[/tex]
Then, diameter ([tex]D[/tex]), measured in milimeters, can be derived from the following volume formula:
[tex]V_{c} = \frac{\pi}{4}\cdot D^{2}\cdot h[/tex] (1)
Where [tex]h[/tex] is the thickness of the coin, measured in milimeters.
If we know that [tex]h = 2\,mm[/tex] and [tex]V_{c} =1212.121\,mm^{3}[/tex], then the diameter of each coin is:
[tex]D^{2} = \frac{4\cdot V_{c}}{\pi\cdot h}[/tex]
[tex]D = 2\cdot \sqrt{\frac{V_{c}}{\pi\cdot h} }[/tex]
[tex]D = 2\cdot\sqrt{\frac{1212.121\,mm^{3}}{\pi\cdot (2\,mm)} }[/tex]
[tex]D \approx 27.779\,mm[/tex]
The diameter of each coin is approximately 2.778 centimeters.

Any help appriciated and needed Thank you!! Will also be marking brainliest
Answer:
4. 380.13 cm²
5. 706.86 cm²
6. 12.57 cm²
Step-by-step explanation:
4. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 22 cm = 11 cm
Area = π*11²
Area = 380.13 cm²
5. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 30 cm = 15 cm
Area = π*15²
Area = 706.86 cm²
6. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 4 cm = 2 cm
Area = π*2²
Area = 12.57 cm²

A shopkeeper fixed the marked price of his radio to make a profit of 30 percentage. allowing rs 30 as a discount then the profit is rs 30. find the cost price
Answer:
rs 200
Step-by-step explanation:
Let cost price = x
At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x
Discount = rs 3%
Profit made = 30
Hence,
Marked price - discount = cost price + 30
130%x - 30 = x + 30
1.3x - 30 = x + 30
1.3x - x = 30 + 30
0.3x = 60
Divide both sides by 0.3
0.3x / 0.3 = 60/ 0.3
x =
1.3x / 1.3 = 60 / 1.3
x = 200
Hence, cost price = rs 200

In ABC, m∠A measures twice m∠B. if exterior angle at C measures 126°, find m∠A
.
2: in abc the measure of the exterior angle at b 100° if m∠A is 4 times larger than m∠C find m∠C.
someone pleaseeeeeeeeeee
Answer:
1) ∠A=84°
2) ∠C=20°
Step-by-step explanation:
1)
First, find ∠C:
(I'm assuming the exterior angle of 126° makes a straight line with ∠C)
The angles on a straight line always add up to 180. Therefore:
∠C+126=180
∠C=180-126
∠C=54
Then find ∠B:
We also know that all the angles in a triangle add up to 180. Therefore:
∠A+∠B+∠C=180
∠A+∠B+54=180
∠A+∠B=126
(we know ∠A=2(∠B))
2(∠B)+∠B=126
3(∠B)=126
∠B=42
Now, find ∠A:
∠A=2(∠B)
∠A=2(42)
∠A=84°
2)
First, find ∠B:
(Again, I'm assuming the exterior angle of 100° makes a straight line with ∠B)
The angles on a straight line always add up to 180. Therefore:
∠B+100=180
∠B=180-100
∠B=80
Then find ∠A:
We also know that all the angles in a triangle add up to 180. Therefore:
∠A+∠B+∠C=180
∠A+80+∠C=180
∠A+∠C=100
(we know ∠A=4(∠C))
4(∠C)+∠C=100
5(∠C)=100
∠C=20°

Answer:
B
Step-by-step explanation:
The answer is B. If you look at the graph at its current state you can see that the lines are parallel to each other. This is important because it says TWO lines are being translated and rotated. So whatever happens to one line happens to the other line which proves they were always parallel to each other.

Step-by-step explanation:
the screen size of a television is determined by the length of the diagonal of the rectangular screen. Traditional TVs come in a 4:3 format, meaning the ratio of the length to width of screen is 4 to 3. what is the area of a 27-inch traditional tv screen? what is the area of a 27 inch LCD tv who's screen is in a 16:9 format? which screen is larger
Answer:
Area of 27" 4:3 screen = 349.92 square inches
Area of 27" 16:9 screen ≅ 311.5 square inches
Traditional 4:3 screen is larger
Step-by-step explanation:
The Traditional TVs is larger than LCD tv screen
What is diagonal of rectangle?The diagonal of a rectangle is a line segment that joins any two of its non-adjacent vertices.
The length of diagonals of a rectangle can be calculated as:
Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]
According to the question
The screen size of a television is determined by the length of the diagonal of the rectangular screen.
Traditional TVs
Ratio of the length to width = 4:3
Let a be the constant for both length and width
therefore
Length of Traditional TVs = 4a
Width of Traditional TVs = 3a
The area of a 27-inch traditional tv screen
i.e
Diagonal of Traditional TVs = 27
Now applying formula of diagonal of rectangle
Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]
substituting the values
27 = [tex]\sqrt{(4a)^{2} + (3a)^{2} }[/tex]
27 = [tex]\sqrt{16a^{2} + 9a^{2} }[/tex]
27 = [tex]\sqrt{25a^{2} }[/tex]
27 = ± 5a
a cannot be -ve
a = 5.4
now,
Length of Traditional TVs = 4* 5.4 = 21.6 inches
Width of Traditional TVs = 3 * 5.4 = 16.2 inches
Area of Traditional TVs = Length * width
= 21.6 * 16.2
= 349.92 [tex]inches^{2}[/tex]
LCD TVs
Ratio of the length to width = 16:9
Let a be the constant for both length and width
therefore
Length of LCD TVs = 16a
Width of LCD TVs = 9a
The area of a 27-inch LCD TVs screen
i.e
Diagonal of LCD TVs= 27
Now applying formula of diagonal of rectangle
Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]
substituting the values
27 = [tex]\sqrt{(16a)^{2} + (9a)^{2} }[/tex]
27 = [tex]\sqrt{256a^{2} + 81a^{2} }[/tex]
27 = [tex]\sqrt{337a^{2} }[/tex]
27 = ± 18.357a
a cannot be -ve
a = 1.47
now,
Length of LCD TVs = 16*1.47 = 23.53
Width of LCD TVs = 9*1.47 = 13.23
Area of Traditional TVs = Length * width
= 21.6 * 16.2
= 311.30 [tex]inches^{2}[/tex]
Hence, the Traditional TVs is larger than LCD tv screen .
