The three most popular ice cream flavors are chocolate, strawberry, and vanilla, comprising 70 % of the flavors
sold at an ice cream shop. If vanilla sells 2 % more than twice strawberry, and chocolate sells for 6 % more than
vanilla, how much of the total ice cream consumption are the vanilla, chocolate and strawberry flavors?
The total ice cream consumption of vanilla, chocolate and strawberry flavours are as follows:
strawberry sells = 12 %
vanilla sells = 2 + 2x = 2 + 24 = 26%
chocolate sells = 8 + 2x = 8 + 24 = 32%
The 3 most popular ice cream flavours are chocolate, strawberry and Vanilla.
This 3 flavours comprises of 70% of the flavour sold at an ice cream shop.
let
% strawberry sells = x
% vanilla sells = 2 + 2x
% chocolate sells = 6 + (2 + 2x) = 8 + 2x
Therefore,
x + 2 + 2x + 8 + 2x = 70
5x = 70 - 10
5x = 60
divide both sides by 5
5x / 5 = 60 / 5
x = 12
Therefore,
% strawberry sells = 12 %
% vanilla sells = 2 + 2x = 2 + 24 = 26%
% chocolate sells = 8 + 2x = 8 + 24 = 32%

Given that the polynomial f(x) has 7 turning points, which of the following most accurately describes the degree of f(x)
Select the correct answer below.
The degree of f(x) is at least 8.
The degree of f(x) is at most 6.
The degree of f(x) is at least 7
O The degree of f(x) is at least 6.
The degree of f(x) is at most 8.
The degree cf) is at most 7
Step-by-step explanation:
the degree of f(x) is at least 8.
a squared function has 1 turning point.
a cubic function has 2 turning points.
and so on.
under certain circumstances some turning points or also zero points can merge into the same point.
formally they all count separately, but practically they are the same.
so, when we can SEE 7 turning points, there must be at least a degree of 8 or more.
a function with lower degree can never "create" additional turning points.

Rania puts $15 000 into a savings account where it earns 4% per annum
compound interest.
a) What is her investment worth after two years?
b)How much interest has she earned?
Part (a)
I'll assume the interest compounds annually.
A = P*(1+r/n)^(n*t)
A = 15000*(1+0.04/1)^(1*2)
A = 16,224
Answer: $16,224====================================================
Part (b)
Subtract the result of part (a) and the original deposit amount to find the interest earned.
interest = A - P = 16,224 - 15,000 = 1,224
Answer: $1,224Answer:
The final balance is $16,236.48.
The total compound interest is $1,236.48

Which school is equidistant from the subway stations at union square and 14th street?
I think it's Catherine School
Equidistant means "same distance"
The distance from 14 Street to Adam School is not the same as the distance from Union Square to Adam School. So this isn't right.
The distance from 14 Street to Catherine School is the same as the distance from Union Square to Catherine School.
So Catherine School is equidistant. Hope it helps!

Brianna planted daffodils and tulips in her garden. She planted 4 daffodils for every 3 tulips. if Brianna planted 28 flowers in all, how many tulips did she plant?
Answer:
12
Step-by-step explanation:
4+3=7
7x4=28
3x4=12
Answer:
Step-by-step explanation:
The ratio is 4 daffodils to 3 tulips.
Let the daffodils = d
Let the Tulips = t
d/t = 4/3 Cross Multiply
3d = 4t Divide by 3
3d/3 = 4t/3 Combine
d = 4/3 * t
d + t = 28
4/3 t + t = 28 Change 1t to 3/3 t
4/3 t + 3/3t = 28 Add the fractions.
7/3 t = 28 Multiply both sides by 3/7
3/7 * 7/3t = 28 * 3/7
t = 4 * 3
t = 12
12 tulips were planted. This is the algebraic method of doing the question. If you are in an algebra class, the question really should be done this way.

Yuan makes punch by mixing cranberry juice and pineapple juice. For every 3 cups of pineapple juice, he uses 2 cups of cranberry juice. How much would make 10 cups? Please help me
call x is the amount of cup of pineapple, and y is the amount of cup of cranberry.
we have:
x + y = 10
x/y = 3/2 => x = (3/2)*y
x + y = 10
=> (3/2)y + y = 10
=> 3y + 2y = 20
=> 5y = 20
=> y = 4
x + y =10
=> x = 10 -4 = 6
=> 6 cups of pineapple and 4 cups of cranberry would make 10 cups

The probability that a baseball player will get a hit is 0.300. What is the probability that he will get one hit in his next two turns at bat
Answer:
0.42.
Step-by-step explanation:
Probability of a miss on one bat = 1 - 0.3 = 0.7.
There are 2 scenarios:
First bat a Hit, Second bat a Miss, or
First bat a Miss, Second bat a Hit.
First scenario: Probability = 0.3 * 0.7 = 0.21.
Second is 0.7 * 0.3 = 0.21.
So the answer is 0.21 + 0.21 = 0.42.

Which of the following properties can be used to show that the expression is equivalent to?
The properties that can be used to show that the expression 5^(3/2) = is equivalent to √5³ is; Option 4
How to use Algebraic Properties?We want to show that the expression 5^(3/2) = √5³
Now, to break it down, we can express the fraction 3/2 as 3(1/2) and so we now have;
5³^(1/2)
Now, any number raised to the power of 1/2 is simply referring to square root and so we now have;
5³^(1/2) = √5³
Thus, option 4 is correct.
