if it takes 10 men 10 days to dig a hole how long will it take 5 men to dig a hole that's half as big

Answer:

Step-by-step explanation:

So we know that it cost $600 in material to build the couch,

and then we know it cost $2000 extra to install and setup the couch,

so it cost 2,600 to build and install one couch,

So the first answer is 2,600

Now to build and install 15 of them we do 2,600 x 15 = $39,000

So it cost 2,600 to make and install one

And 39,000 to make and install 15.

But it only cost $600 to build one

and $9,000 to make 15 without installation fees.

Answer and Step-by-step explanation:

To solve for d, divide f from both sides of the equation.

df ÷ f = (g + 32) ÷ f

d = [tex]\frac{g+32}{f}[/tex] is the answer.

Answer:

x < 3

Step-by-step explanation:

11 > 2 + 3x

3x + 2 < 11

3x (+ 2 - 2) < 11 - 2

3x < 9

3x/3 < 9/3

x < 3

Answer:

3 >x

Step-by-step explanation:

11>2+3x

Subtract 2 from each side

11-2>2-2+3x

9 > 3x

Divide each side by 3

9/3 > 3x/3

3 >x

Answer:

a) linked a screenshot of the graph.

b) when y=1 x=.5

Step-by-step explanation:

4 is the slope, which makes the graph angle different. Starting at the origin (0,0) if you go over 1 and up 4 that is how you can draw the slope on a graph.

-1 makes the line go to the right 1 time so instead of the graph being on the origin (0,0) it will be placed on the coordinate points of (1,0)

To find the x value. Find 1 on the y-axis of the line graph. Go to the right to find where the line intersects. After you find that go straight down to find the x-value (0.5)

Answer: x = -19

Step-by-step explanation:

Answer: slope = 2

Step-by-step explanation:

slope formula is y2-y1 / x2-x1

let’s make 5, x1 and -1, x2, 4, x2 and -3, y2.

if you plug the numbers in it should look like

-3 - -1 / 4-5 = -2/-1 = 2 (positive two). it’s a positive 2 because a negative times a negative is a positive and a positive times a negative is a negative

Given that,

Mary Smith ordered 3/4 truckload of merchandise.

If approximately 1/3 of the merchandise has been unloaded.

To find,

How much remains to be unloaded?

Solution,

Remaining amount = Total truckload - Unloaded amount

Let x is the remaining amount. So,

[tex]x=\dfrac{3}{4}-\dfrac{1}{3}\\\\x=\dfrac{3(3)-4}{12}\\\\x=\dfrac{5}{12}[/tex]

Answer:

So, the remaining amount is [tex]\dfrac{5}{12}[/tex].

Reference:

https://brainly.com/question/10445856

Using formula:

Remaining amount = Total truckload - Unloaded amount

Calculating the remaining amount:

[tex]\to \bold{x=\frac{3}{4}-\frac{1}{3}}\\\\[/tex]

       [tex]\bold{=\frac{3\times 3-4}{12}}\\\\\bold{=\frac{9-4}{12}}\\\\\bold{=\frac{5}{12}}\\\\\bold{=0.416}\\\\[/tex]

Therefore, the remaining amount is "0.416"

Answer:

 = 1/ (3x-2)

Step-by-step explanation:

H(x) = 1/(x+2)

k(x) = 3x - 4

h[k(x)] =  place the function k(x) in for x in the function h(x)

           = 1/(3x-4 +2)

Combine like terms

           = 1/ (3x-2)

Hey there! I'm happy to help!

What we need to do is take the value of k(x) which is 3x-4 and plug it into the function h(x).

This is because our x in the function h[k(x)] is k(x), so we will substitute that value for x in that formula and that will give us our answer.

H[(k(x)]=1/(3x-4+2)

And combine like terms

H[(k(x)]=1/(3x-2)

So, our answer is C. 1/(3x-2)

Answer:

All are rational numbers.

Step-by-step explanation:

1)0.032 is rational because it is terminating number.A terminating number is always rational.

2)20/4=5. It is also a rational number becasue 5 is natural/whole number.They are also rational.

3)-2 is an integer and also falls in rational numbers.

4)-2/3=-0.666.....

It is a non-terminating and recurring number.This category also falls in rational.

5)99/2=49.5

It is also a terminating number it is a rational number.
