The percentage of the skateboards that were longboards is 30%.
Number of skateboards ordered = 60
Number of skateboards that were longboards = 18
Therefore, the percentage of the skateboards that were longboards will be:
= 18/60 × 100
= 30%
Therefore, the percentage of the skateboards that were longboards is 30%.

Answer:
30 percent
Step-by-step explanation:
18/60= 0.3 multiply by 100 to get your percent
Answer: 13 attendees
Step-by-step explanation: 52/4=13
Answer:
Step-by-step explanation:
sample response : Let the variable x be the number of packs purchased, and 12x = total number of water bottles. Since 11 are removed, 12x - 11 is the total she needs to store. So, 12x - 11 must be less than or equal to 65. Solving this, you get x is less than or equal to 6 1/3. This means Kate should buy a maximum of 6 12-packs, since she cannot buy part of a 12-pack.
Answer:
Equation 3
Step-by-step explanation:
Lets see which of the functions has -2 as a zero root. We will go in order:
(1) (-2)^4 - 3(-2)^3 + 3(-2)^2 -3(-2) + 2 = 16 - 3(-8) + 3(4) + 6 +2 = 16 +24 +12 + 6 +2 =60 >0
So, (1) is wrong!
(2) (-2)^4 + 3(-2)^3 + 3(-2)^2 - 3(-2) - 2 = 16 - 24 + 12 + 6 - 2 =34 - 26 = 8 > 0
(2) is also wrong!
(3) (-2)^4 + 3(-2)^3 + 3(-2)^2 +3(-2) + 2 = 16 - 24 + 12 - 6 + 2 = 30 -30 = 0
The zero root x=-2 fits, what about x=-1?
(-1)^4 + 3(-1)^3 + 3(-1)^2 +3(-1) + 2 = 1 - 3 + 3 - 3 + 2 = 6 - 6 = 0
So, equation (3) fits both!
Finally, lets see (4):
(-2)^4 - 3(-2)^3 - 3(-2)^2 + 3(-2) + 2 = 16 + 24 - 12 - 6 + 2 = 42 - 18 = 24 > 0
So, (4) is also wrong.
Only equation 3 fits both zero roots!
The quartic function with x=-1 and x=-2 real roots is x^4+6x^3 +12x^2+12x+4. Quartic functions are polynomial functions of degree 4; quadratic equations resources also help understand the concept. In essence, finding roots of quartic functions follow the same logic as that of quadratic functions.
The subject matter pertains to quartic functions in mathematics. Quartic functions are polynomial functions with a degree of 4. From the question, the given zeros are x=-1 and x=-2, having multiplicity of 2 each (since there are only two real zeros). Thus, the quartic function with these zeros will be (x+1)^2*(x+2)^2. This can be expanded to x^4+6x^3 +12x^2+12x+4.
Exemplifying the relevance of The Solution of Quadratic Equations, normally known as second-order polynomials or quadratic functions, such equations can also be used to find zeros of the functions when set to equal zero. In this scenario, quartic functions are a degree higher, but the same principle applies in finding the roots when the equation is set equal to zero.

The total number of children in the club is given by the equation A = 160 students
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of students be represented as A
Now , the equation will be
The number of students who went to the matinee = 40 students
The percentage of students who went to the matinee = 25 %
So ,
percentage of students who went to the matinee x total number of students = number of students who went to the matinee
Substituting the values in the equation , we get
( 25 % ) x A = 40
On simplifying the equation , we get
( 25/100 ) x A = 40
A / 4 = 40
Multiply by 4 on both sides of the equation , we get
A = 160 students
Therefore , the value of A is 160 students
Hence , the equation is A = 160 students
