Answer:
length = 20 feet and width = 5 feet
Step-by-step explanation:
Volume is equal to volume = height * width * length. The questions tells us the total volume is 200 cubic feet and that the lenght is equal to length = 4w. Set up the equation 4w * w * 2 = 200 cubic feet. Multiply to get 8w^2 = 200 and solve for w.

What is the vertex of the parabola?The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of a parabola.
The standard equation of the vertex of the parabola is;
[tex]\rm a(x - h)^2 + k[/tex]
Where h and k are the coordinates of the vertex of the parabola.
The given expression is;
[tex]\rm =3x^2 - 12x + 7\\\\= 3(x^2 - 4x) + 7\\\\ = 3[ (x - 2)^2 - 4)] + 7\\\\= 3(x - 2)^2 - 12 + 7\\\\= 3(x - 2)^2 - 5[/tex]
On comparing with the standard form of vertex of the parabola
h = 2 and k = -5
Hence, the vertex of g(x) = [tex]\rm 3x^2 - 12x + 7[/tex] is (2, -5).

Answer:
2 cats
Step-by-step explanation:
12% of 24 = 2.88
Answer:
2 cats were adopted.
Step-by-step explanation:
When finding a percentage of something, heres a trick. Just take the number you taking the perccentage of, and mutiply it by the percentage. In this case, 24*12.
24*12 = 288.
Now take that new number and divide it by 100. Now you have your answer. In this case,
288/100 = 2.88.
Becuase these are cats, we can't have or adopt half of one XD. You can't adopt half of a cat, so we round it down to 2. Meaning, 2 cats were adopted.

Step-by-step explanation:
first, we need to divide 600 by 50, to get them organized for the best packages. 600/50 = 12.
then, we multiply that (the 12) by the cost ($12/ea) so 12*12 which is $144 if they use the bundling.

Half of the product of two consecutive numbers is 105. which equation can be used to solve for n, the smaller of the two numbers? n2 n – 210 = 0 n2 n – 105 = 0 2n2 2n 210 = 0 2n2 2n 105 = 0
The equation that can be used to solve for n, the smaller of the two numbers would be n² + n - 210 = 0.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
If we use n to be the smaller number of two integer numbers, then the next consecutive number is n + 1.
The product of those two numbers would become n × (n + 1) = n (n + 1).
Half of that product is n (n + 1) / 2.
And the question states that the equation is equal to 105, so the equation becomes,
n (n + 1) / 2 = 105
Now we have to simplify that equation until we get an expression equal to one of the choices,
Multiply both sides by 2
n (n + 1) = 210
n² + n = 210
Subtract 210 from both sides
n² + n - 210 = 0
Thus, the equation formed is the quadratic equation.
