Factorise fully
5ac - 10a2b + 30a​

For the given equation:

m = 3b

The constant of proportionality is 3, so the correct option is A.

How to determine the constant of proportionality?

After a small search on the internet, I've found that this question asks for the constant of proportionality.

Remember that a proportional relation is of the form:

y = k*x

Where k is the constant of proportionality, and x and y are the variables.

Here the relation is:

m = 3*b

Where m and b are the variables, then the remaining coefficient is the constant of proportionality, which is 3.

In this way, we can see that the correct option is A.

Answer:

it is 3 since thats the only number there

Answer: 4,781

Step-by-step explanation:

if 2,049 (tickets sold in 3 days) is divided by 3 (days) it would be 683 (tickets sold each day)

683 (tickets sold a day) times 7 (days in a week) is 4,781.

Answer:

b

Step-by-step explanation:

how it works with life

Answer: Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).

Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).

Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes

Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes

After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.

So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.

If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.

Step-by-step explanation:

Answer:

A/B

Step-by-step explanation:

They will have enough popcorn

Either way there will be enough popcorn to make eight 9-ounce bags.

Answer:

(12, -11) represents (x, y)

so 12 is x

-11 is y

now we need to do

x-9 and y+9

x-9=

12 - 9 = ???

y+9=

-11 + 9 = ???

then put into formate (x, y) as before

if you need more help comment and please put as brainiest

69.50 +(3 x 5) = 84.5

Note- It seems something is missing from this problem,I answered you other question you may want to look their for better explanation of the problem.

HOPE THIS HELPS & GOOD LUCK.

Answer:

5x + 15y =20  = - 3x +25y =75

= 8 minutes

Step-by-step explanation:

5x + 15y =20    multiply all by 3 to get 15x

15x +45y=60

- 3x +25y =75 multiply all by -5 to get 15x

15x -125y = -375

rewrite ans together

15x +45y=60

15x -125y = -375

      -80y = -315

y = -315/ - 80

y = 3.9375  = y= 4 substitute to find x

5x + 15(4 )=20  

5x +60 = 20

5x=-40

x= -40/5

x=-8

15x +45(4)=60

15x +180 =60

15x =-120

x=-8

i hope it helps u :-)

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

Therefore, \(2x^{2}+18=0\) has no real roots

Answer:

Step-by-step explanation:

0 has no roots so thats one, and im just trying to complete a challenge so sorry if im wrong :( but make other person brainliest they did good job :)

Answer:

A=962 in^2

Step-by-step explanation:

Area of a trapezoid is 1/2(base 1 + base 2) *h

Base 1= 40

Base 2=34

Height(h)=26

So...

A=1/2(34+40)*26

A=1/2(74)*26

A=962 in^2

Answer:

Step-by-step explanation:

He is multiple decimals

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

$101.85

Step-by-step explanation:

Think of the two days as separate equations. They are added together to get a sum of the pay she will receive after the two days.

Equation

(4.5*10.5) + (5.2*10.5) = x (This just represents the unknown value)

Solve Through

(47.25) + (54.60) = x

47.25 + 54.60 = x

101.85 = x

Amanda will get paid $101.85 For her 2 days of work.

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A
