What is the LCM of 600 and 1050?
Thanks :)
Answers
Answer:
4200
Step-by-step explanation:
The least common multiple (LCM) is the product of the unique factors of the numbers:
600 = 4 × 150
1050 = 7 × 150
LCM(600, 1050) = 4×150×7 = 4200
_____
The above factoring may also help you see that the LCM is also the product divided by the greatest common factor:
LCM(600, 1050) = 600 × 1050 / GCF(600, 1050)
= 600 × 1050 / 150
= 4200

c is inversely proportional to d.
c=0.5 when d=6
Find a formula for c in terms of d.
Answers
I think this is the answer!
c=3/d
The formula for c in terms of d is c= 3/d
What is Constant of proportionality?The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional. When y and x are two values that are directly proportional to one another, the proportionality constant k is defined as k=y/x.
Given:
c=0.5 when d=6
We know that c is inversely proportional to d.
c ∝ 1/d
c = k / d
and, k = cd
k = 0.5 x 6
k = 3
Hence, the formula for c in terms of d is c= 3/d

A group of 83 students are visiting the National Aquarium in Baltimore. Volunteers lead tours for groups no larger than 5 students at a time. How many tour guides are needed so all 83 students are able to participate in a guided tour of the aquarium
Answers
Answer:
17 tour guides
Step-by-step explanation:
First, we need to divide 83 by 5.
83 ÷ 5 = 16 R 3As you can see, there are 16 tour guides that can handle 5 students each. However, there are a remainder of 3 students, so we need one extra tour guide. Thus, the answer is 17 tour guides.
Answer:
They need 17 tour guides
Step-by-step explanation:
If we divide 83 by 5, we would get 16.6, and since we can't have 16.6 tour guides, we round to the nearest whole number, which is 17.
To order for all students to participate, they would need 17 tour guides.

Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).
Answers
Answer:
[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]
Step-by-step explanation:
Vertex: (3,2)
Point: (13,8)
The equation form is [tex]y=a(x-h)^2+k[/tex]
h = 3
k = 2
y = 8
x = 13
Plug in the values into the form..
[tex]8=a(13-3)^{2} +2[/tex]

Which equation is represented by the model? x2 – 2x – 3 = (x – 3)(x 1) x2 – 4x 3 = (x – 3)(x – 1) x2 2x 3 = (x 3)(x – 1) x2 4x – 3 = (x 3)(x 1).
Answers
The equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
What is algebraic model?Algebraic model are the expression which consist the variables, coefficients of variables and constants.
The algebraic model are used represent the general problem in the mathematical way to solve them.
Let's check the first option,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 2x - 3 = x^2+x-3x-3\\x^2 - 2x - 3 = x^2-2x-3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Second option is given as,
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 4x+ 3 = x^2 -x-3x+3\\x^2 - 4x+ 3 = x^2 -4x+3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Third option is given as,
[tex]x^2 +2x+ 3 = (x +3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +2x+ 3 = x^2 -x+3x - 3 \\x^2 +2x+ 3 = x^2 +2x - 3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Forth option is given as,
[tex]x^2 +4x - 3 = (x+ 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +4x - 3 = x^2+ x+3x +3\\x^2 +4x - 3 = x^2+4x +3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Hence, the equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

If f(x)=x^2+3 and g(x)=2x-5 find (f-g) (x)

We have the following two functions:
[tex]f(x)=x^2 +3g(x) = 2x-5[/tex]
In order to solve for [tex](f - g)(x)[/tex] we look at the two functions and realize that:

the 14 cars sold = 56% of total car stock
how many cars (noted n) for 100 % ?
14.............56%
n..............100%
n x 56% = 14 x 100%
n = 14 : 0,56
n = 25
total cars in stock : 25
56% were sold
so 25 x 56% = 14 have been sold
