Answer:
283cm^2 Hope that helps ;)
Step-by-step explanation:
The approximate surface area of the cone is 283 cm².
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Given that,
The circular base of a cone has a radius of 5 centimeters.
The height of the cone is 12 centimeters, and the slant height is 13 centimeters.
Surface area of a cone = π r² + πrl
where r is the radius and l is the slant height.
Substituting,
Surface area = π (5)² + π(5)(13)
= 25π + 65π
= 90π
= 90 × 3.14
= 282.6 cm² ≈ 283 cm²
Hence the surface area is 283 cm².

Which writing algebraic expression correctly translate 2n + 8
The correct translation for the expression 2n + 8 is "eight more than twice a number."
The expression 2n + 8 represents doubling a number (represented by n) and then adding 8 to it. In simpler terms, it signifies performing the operation of multiplication (twice the number) followed by addition (adding 8). So, when we say "eight more than twice a number," it perfectly encapsulates this mathematical operation: first, we double the number, then add 8 to the result. This succinctly describes the algebraic expression 2n + 8 in a clear and concise manner.
Complete Question:
Which written algebraic expression correctly translate 2 n+8 ?
A. eight more than twice a number
B. eight plus double a number
C. a number squared added to eight

Question 1
How can you rewrite the following expression?
Your answer:
4- 2 = 2
4+ (-2) = 2
4+2 = 6
INTL
The expression '4 - 2 = 2' can be rewritten as '4 + (-2) = 2' or 'subtracting 2 from 4 equals 2'. However, '4 + 2 = 6' is not equivalent to the initial expression and represents an addition, not a subtraction.
Explanation:The expression '4 - 2 = 2' can be rewritten in a number of ways. Firstly, we can consider '4 - 2' as '4 + (-2)', which indeed equals 2. Moreover, another way to rephrase '4-2' is 'subtracting 2 from 4', still equals 2. A different expression, '4 + 2', however, results in a value of 6, which is not equivalent to our initial expression '4 - 2 = 2'.
We use the concepts of addition and subtraction to rewrite these expressions. It is crucial to understand that the operation of subtraction can be imagined as the addition of a negative number to a positive one. Whereas, the operation 4 + 2 = 6 belongs to a different category, as it is straightforward addition, not a subtraction.

Which number produces
irrational number when added to 3/4?
A. 3.14 (pie)
B. 0.333...
C. 3/5
D. -0.75
Answer:
A is the answer.
Step-by-step explanation:
A fraction plus a fraction is equal to a fraction. An irrational number cannot be expressed as a fraction.
0.3333333 even though it looks like an irrational number it is actually: 1/3
3/5 is already a fraction so adding it with another fraction will NOT equal an irrational number (decimal)
-0.75 is equal to -3/4 (75/100 => 3/4). Same thing that applies above.
However, Pi cannot be expressed as a fraction exactly. You can round up like 3.14. However it is not the full number. So 3.141592654....+(3/4) is not going to add up perfectly into a fraction.
In short, a fraction is a rational number. Rational + Rational = Rational. Irrational + Rational = Irrational.
Answer:
A (pi)
Step-by-step explanation:
Pi is already an irrational number, therefore, anything added to it must become irrational

Step-by-step explanation:
The system of equations that matches the graph is
x + y = 2
3x - y = 1
What is the system of equations
From the question, we are to write a system of equations for the two straight lines shown
To do this, we will pick two points on each line
Red line:
(0, 2) and (2, 0)
Using the formula,
y - y1 / x - x1 = y2 - y1 / x2 - x1
(y - 2) / (x - 0) = (0 - 2) / (2 - 0)
Simplifying
(y - 2) / x = -2 / 2
(y - 2) / x = -1
y - 2 = -x
Thus,
x + y = 2
Blue line:
(1, 1) and (0, -2)
Using the formula,
y - y1 / x - x1 = y2 - y1 / x2 - x1
(y - 1) / (x - 1) = (-2 - 1) / (0 - 1)
Simplifying
(y - 2) / (x - 1) = -3/ -1
(y - 2) / (x - 1) = 3
y - 2 = 3(x - 1)
y - 2 = 3x - 3
Thus,
3x - y = -2 + 3
3x - y = 1
Hence,
The system of equations is
x + y = 2
3x - y = 1
What is the volume of this cylinder?
Use n = 3.14 and round your answer to the nearest hundredth.
Answer:
12762.72 cubic meters
Step-by-step explanation:
The volume of a cylinder is denoted by the formula: [tex]V=\pi r^{2} h[/tex], where r is the radius and h is the height.
Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.
Now substitute these values into the equation:
[tex]V=\pi *(18.8^2)*11.5=3.14*(18.8^2)*11.5=12762.72[/tex] cubic meters
Hope this helps!
Answer:
[tex]12769.19m^{3}[/tex]
Step-by-step explanation:
The formula for the area of a circle is:
[tex]\pi r^{2}[/tex]
To work this out you would first have to find the area of the circle. To do this you would first divide 37.6 by 2, which gives you 18.8. Then to find the area you would multiply pi by 18.8 squared, which gives you [tex]1110.36m^{2}[/tex]. Then To find the volume you would multiply 1110.36 by 11.5, which gives you [tex]12769.19m^{3}[/tex].
To find the volume of a prism you would find the area of the main face and multiply it by the height.
1) Divide 37.6 by 2.
[tex]37.6/2=18.8[/tex]
2) Multiply [tex]\pi[/tex] by 18.8 squared.
[tex]\pi *18.8^{2}=1110.36m^{2}[/tex]
3) Multiply 1110.34 by 11.5.
[tex]1110.36*11.5=12769.19m^{3}[/tex]
Remember when finding the area, thee answer is always going to be squared.
Remember when finding the volume the answer is always going to be cubed.
Junior's box of animal crackers contains ten elephants, ten monkeys, ten zebras, and ten lions. Without looking, Junior grabs one cracker from the box and eats it. What is the probability that both crackers were lions?
Answer:
3/52
Step-by-step explanation:
10/40 x 9/39 = 3/52
Final answer:
The probability that both animal crackers Junior grabs from the box are lions is approximately 5.75%.
Explanation:
The question asks to calculate the probability that both animal crackers Junior grabs from the box are lions. With a total of 40 animal crackers (10 elephants, 10 monkeys, 10 zebras, and 10 lions), the probability of picking a lion first is 10/40 or 1/4. After eating one lion, there are now 39 crackers left and only 9 lions. The probability of picking a second lion is 9/39. To find the probability that both crackers eaten are lions, we multiply the probabilities of these two independent events: (1/4) * (9/39) = 9/156 or 1/17.39. This simplifies to approximately 0.0575 or 5.75%.
Eleana and her grandfather both had birthdays last week.
• The sum of their ages is 100 years.
• Her grandfather's age is 4 times Eleana's age.
How old is Eleana and her grandfather?
Answer:
Eleana is 20 years old and her grandfather is 80 years old.
Step-by-step explanation:
So first off, we want to make variables to represent Eleana and her grandfather.
Let x represent Eleana's age.
Since her grandfather is four times older than Eleana,
The expression should be 4x+x=100
Step One
Add the x's together and you get 5x=100.
Step Two
Divide both numbers by 5 to solve for x.
x=20

is this a function?
true or false
Answer:
false
Step-by-step explanation:
it fails the vertical line test, (x cannot be equal to 2 or more y values or its not a function)
To check if a graph is a function, we use the vertical line test. If your run a vertical line over the function, are there any places where the line intersects the graph more than once? If so, it's not a function.
In this case, if we have a line at x = 0, the line will go through more than one point - (0, 0) and (0, 3.1) [exact value doesn't matter, what matters is that there's a point there]. That means that this is not a function, so the statement is false.
