Answer: cone Cylinder
Surface area is 402ft2 and 69ft2
Step-by-step explanation:
I got the answer right
The appropriate shape to model trunk is cylinder, rest of the tree is cone and surface area of trunk is 25.12 [tex]feet^{2}[/tex]and surface area of rest of the tree is 415.58 [tex]feet^{2}[/tex].
What is surface area?It is the space occupied by a two dimensional surface. The area occupied by a three dimensional object by its outer surface area.
How to calculate surface area?The upper part of the tree is similar to the cone and the trunk is of cylindrical shape. So the appropriate shape used to model the entire is cone above the cylinder.
We have been given the height of entire tree=30 feet,
Width of upper part=10 feet.
Height of trunk=4 feet
Width of tree means diameter of upper part or cone. Height of cone means height of cylinder, width of trunk means diameter of cone.
So, The radius of cone ie 5 feer,radius of cylinder is 1 feet, height of cone be 30-4=26 feet.
Surface area of cone is πrl where l is slant height of cone which is equal to [tex]\sqrt{r^{2} +h^{2} }[/tex]
l=[tex]\sqrt{5^{2} +26^{2} }[/tex]
=[tex]\sqrt{701}[/tex]
=26.47 feet.
Surface area of cone=π*5*26.47
=3.14*5.26*26.47
=415,28 [tex]feet^{2}[/tex]
Surface area of cylinder=2πrh
=2π*4*1
=2*3.14*4
=25.12 [tex]feet^{2}[/tex]
Hence cone and cylinder of surface area 415.28 [tex]feet^{2}[/tex] and 25.12 [tex]feet^{2}[/tex] can be used to model out tree.

Are the ratios 16:8 and 2:1 equivalent?
Thus 16:8 and 2:1 are equivalent.
→ 16:8
divide both by 8

simplify
→ 2 : 1
Answer:
Yes! Because they are in proportion: 1x8 = 8, 2x8 = 16 therefore, 2:1 and 16:8 are equivalent. Similar to equivalent fractions - you need to multiply both numbers by the same number.

One piece of wheat bread contains 2 g of fiber or 8% of the amount of fiber that most people need in a day. What is 8% written and decimal and fraction?
8% written and decimal and fraction are 0.08 and 2/25 respectively
Writing percentage in decimal formGiven the percentage of fiber expressed as 8 %
We are to write 8% in both decimal and fraction form
Decimal form of 8% is 0.08
Fractional form of 8% = 8/100 = 2/25

ANYONE GOOD AT MATH NEED HELP
Answer:
*I just learned that in probability if a question has 'and' it means you multiply and if it has 'or' it means you add*
1a) 1/6
There are two numbers greater than four (5 and 6). There are 6 possible numbers you can get, so the fraction would be 2/6, or simplified would be 1/3. There are two options you can get when flipping a coin, so the chance of getting a head is 1/2. This is an 'and' problem so multiply 1/3•1/2 and you get 1/6.
1b) 1/4
There are 3 even numbers (2, 4, and 6), so the probability would be 3/6 or simplified to 1/2. The chance of landing on a tail is also 1/2, as there are two possible options. This is an 'and' problem so multiply 1/2•1/2 and you get 1/4.
2) 1/8
Write out your possible results: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.
3a) 1/8
There are 4 shirt options to choose from. The chance of picking blue is 1/4. There are 2 pant options. The chance of picking black is 1/2. This is an 'and' problem, so multiply 1/4•1/2 and you get 1/8.
3b) 1/4
There are 4 shirt options to choose from. This is an 'or' problem because he can choose an orange shirt OR a red shirt. The probability of picking an orange shirt is 1/4 and the probability of picking a red shirt is 1/4. 'Or' means you use addition so add 1/4+1/4 and you get 2/4 or simplified is 1/2. There are 2 pant options to choose from, so the probability of choosing brown pants is 1/2. Now, this is an 'and' problem, so multiply 1/2•1/2 and you get 1/4.

Step-by-step explanation:
there are 5 possible events (01234)- there are 3 favorable outcomes (123)
so that's 3 out of 5 or 3/5 or 60%
The estimated probability of a success is 3/5 or 60%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

What is it called when you can not factor an equation
Answer:
polyminal
Step-by-step explanation:
A polynomial with integer coefficients that cannot be factored into polynomials of lower degree , also with integer coefficients, is called an irreducible or prime polynomial . Example 1: x2+x+1.
Example 2:
The polynomial
x2−2
is irreducible over the integers. However, we could factor it as
(x−2√)(x+2√)
if we are allowed to use irrational numbers. So the irreducibility of a polynomial depends on the number system you're working in.

They need to park the Mystery Machine. They could either park in the lot that charges $5 and then $2 an hour, or they could park using the meter on the street that charges $3.75 per hour.
Write an equation that describes when the cost is the same at both locations (the parking lot and on the street).
Please, I just need an equation
Answer: 5 + 2x = 3.75x
Step-by-step explanation:
From the question, they could either park in the lot that charges $5 and then $2 an hour, or they could park using the meter on the street that charges $3.75 per hour.
The equation that describes when the cost is the same at both locations goes thus:
Let the number of hours used be x
The equation can then be written as:
$5 + $2x = $3.75x
5 + 2x = 3.75x

Answer:

Step-by-step explanation:
Foil the equation!
1. You see that is to the second power so it means this [tex](6n+1)*(6n+1)[/tex]
2. Then you use the Foil method. First, Outside, Inside, and Last.
3. Combined like terms
4. Answer!
A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)
1. Multiply the first number by itself = [tex]6n *6n = 36n^2[/tex]
2. Add the first number by itself = [tex]6n+6n = 12n[/tex]
3. Multiply the last number by itself = [tex]1*1 =1[/tex]
4. Combined to form your answer = [tex]36n^2+12n+1[/tex]

If you flip the coin 96 times,how many heads?
If this is a good coin meaning that the head has as many chances as being flipped as a tail then you can expect 48.
There are only two options per flip and thus both sides have an even chance of getting flipped. So each would have half the number of flips to be flipped.

George wrote an integer. The opposite of George's integer is -53. Which of these statements about George's integer must be true? I. The integer is 53. II. The integer has an absolute value of -53. III. The integer is -53. IV. The integers has an absolute value of 53.
Answer: The integers has an absolute value of 53.
Step-by-step explanation:
Given that:
George wrote an integer ;
Let integer = y
Opposite of integer = - 53
From the options given, the best conclusion that must be true is to say George's integer has an absolute value of 53. Because an absolute value clears our doubt of the integer being positive or negative. Also, an absolute value cannot be negative.
Also, an integer of - 53 cannot have an opposite value of - 53
