I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?

vazorg [7]

Answer:

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.

Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into

ANEK [815]

Answer:

-3/5x + y = - 26/5

Step-by-step explanation:

First, I put everything in slope-intercept form, just because it's more simple for me.

y = 3/5x + b

Since we don't have b, we can use the coordinate they give us to solve for it.

-4 = 3/5 (2) + b

-26/5 = b

y = 3/5x - 26/5

Now, we can move the variables around to fit the form:

Ax + By = C

-3/5x + y = - 26/5

I hope this helped!

Need to find the number for a

Shalnov [3]

Answer to the first triangle: 15

To solve this we will use the Pythagorean theorem

Pythagorean theorem formula: $a^{2} + b^{2} =c^{2}$

Lets do the first triangle.

17 is the hypotenuse, so its going to replace c in the formula.

8 is the height and it is going to replace a in the formula.

a is what we are trying to find, so our b in the equation is going to be the unknown.

$8^2 + b^2 = 17^2$

$64 + b^2 = 289

$

$b^2 = 289 - 64$

$b^2 = 225$

$\sqrt{b^2} = \sqrt{225}$

$b = 15$

now we know that the missing length in the first triangle (a) is 15

Can you solve the Other one?

Just comment if you need help on the other one.
