Answer:

B is your answer.

Step-by-step explanation:

Depends on 18/36 = 72/444, because 444 doesn't make sense at all. None of the others are equivalent. If it's 72/144 then this is the answer

Hope this helps.

Brian can lay a slab of concrete in 6 hours, while Greg can do it in 4 hours. If Brian and Greg work together, how long will it

anastassius [24]

Answer:

2 2/5 hours

Step-by-step explanation:

In 6 hours Brian can lay 1 slab of concrete

dividing both side by 6

in 6/6 hours Brian can lay 1/6 slab of concrete

Thus, in 1 hour Brian can lay 1/6 slab of concrete

In 4 hours Greg can lay 1 slab of concrete

dividing both side by 4

in 4/4 hours Greg can lay 1/4 slab of concrete

Thus, in 1 hour Greg can lay 1/4 slab of concrete

Thus, total part of slab laid by both in 1 hour when they work together

1/6 + 1/4 = 4+6/(6*4) = 10/24 = 5/12

5/12 of slab of concrete is laid by both of them in 1 hour

time taken to lay 5/12 of slab = 1 hour

dividing both side by 5/12

time taken to 5/12/ 5/12 of slab = 1/5/12 hour = 12/5 hours

time taken to 1/1 of slab = 12/5 hours = 2 2/5 hours

Thus,

it takes 2 2/5 hours to lay the full slab of concrete when Brian and Greg work together,

Twenty four over the quantity of 3 x minus two. Find f(−2).

TEA [102]

Answer:

f(-2) = -3

Explanation:

Not sure if those last couple numbers are answer choices, but I'm going to infer that they might be.

Twenty four over the quantity of 3 x minus two in standard form is:

f(x) = 243x−2

Since the number in the ( ) = x, plug in for x using f(-2)

243∗(−2)−2

P E {M D} {A S} for where to solve first

Multiply the 3 and (-2):

24−6−2

Add -6 and -2:

24−8

Divide the rest:

f(-2) = -3

How do I do this trying my best but I can’t please help T_T

Sever21 [200]

Use algebra.

Let the number of stickers each had in the beginning = x stickers.

Ray lost 10 we represent this by

x - 10 ( = no. stickers he has now)

Tom bought 200 so the number of stickers he now has

= x + 200

Rays has 1/4 as much as Tom so we can now create the equation

1/4(x + 200) = x - 10

Soling for x:-

1/4 x + 50 = x - 10

60 = 3/4 x

x = 60 * 4/3 = 80

Answer they had 80 stickers at first.

Using the graphing tool, determine the function for the graph that passes through the points (2.1,2.4), (4.3,6.8), and (6.1,1.9)

Paha777 [63]

Answer:

f(x) = -1.18056x² +9.55556x -12.4604

Step-by-step explanation:

As required by the problem statement, technology was used to find the polynomial function that passes through the given points. The coefficients shown above are rounded to 6 significant figures. The exact coefficients appear to be ...

f(x) = (-1 13/72)x² +(9 5/9)x -(12 221/480)
