Whats the GCF of 18 and 30?

Answers

Answer 1
Answer:
Well I don't know !
Let's figure it out:

-- The factors of  18  are  1,  2,  3,  6,  9, and 18 .

-- The factors of  30  are  1,  2,  3,  5,  6,  10,  15, and  30 .

-- The numbers that are factors of both  18  and  30  (the 'common' ones)
    are  1,  2,  3,  and  6 . 

-- The biggest one on that short list (the 'greatest common' one) is  6 .

Which expression could be used to solve the problem? Gem counted 54 wheels on 3 semitrucks. The same number of wheels were on each semitruck. How many wheels were on each semitruck? A. B. 54 • 3 C. 54 – 3 D. 3 + 54

Answers

Here, we could simply divide the values. 

54/3 = 18

So, the correct answer is :-

54 divided by 3
54/3 = 18
which concludes 18 wheels on one semitruck. ( seems a lot for me :) )

What is the height, width, and length

Answers

so, let's say the length is "L".

width = 2 shorter than L = L - 2.

height = 9 more than twice L = 2L + 9.

check the picture below.

keeping in mind that the volume of a rectangular prism is simply the product of its length, width and height, and since we know the volume has to be 45.


\bf 45=(L)(L-2)(2L+9)\implies 45=(L)(2L^2+5L-18) \n\n\n 45=2L^3+5L^2-18L\implies 0=2L^3+5L^2-18L-45 \n\n\n \stackrel{\textit{now let's do some grouping}}{0=(2L^3+5L^2)-(18L+45)}\implies \stackrel{\textit{common factor}}{0=L^2(2L+5)-9(2L+5)}


\bf \stackrel{\textit{again common factor}}{0=\underline{(2L+5)}(L^2-9)}\implies \stackrel{\textit{difference of squares}}{0=(2L+5)\stackrel{\downarrow }{(L^2-3^2)}} \n\n\n 0=(2L+5)(L-3)(L+3)\implies L= \begin{cases} -\cfrac{5}{2}\n[1em] \boxed{3}\n -3 \end{cases}


from those 3 factors, we get those solutions/zeros.

we can't use -5/2, or -3, because the length can't be a negative value, so L = 3.

that means the width = 3 + 2, and the height = 2(3) +9.

You mix the letters S, E, M, I, T, R, O, P, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability that you select a vowel. Write your answer as a fraction in simplest form my answer is B check my work plz

Answers

Easy, the answer is 5/12
Here, Favorable Outcomes(Vowels): E, I,O, I,A = 5
Total Outcomes: S, E, M, I, T, R, O, P, I, C, A, L = 12

So, Probability = Favorable Outcomes / Total Outcomes
P = 5 / 12

In short, Your Answer would be 5/12

Hope this helps!
