Step-by-step explanation:

Take the decimal out an put the number over 1000.

= 505/1000

Find a common denominator

505/5 = 101

1000/5 = 200

Reduce

505/1000 = 101/200

Write a division problem that will have a 2 digit quotient and another division problem that will have a 3 digit quotient. Expla

o-na [289]

Answer:

$\frac{240}{4} =60$

$\frac{1800}{3} =600$

Step-by-step explanation:

1. The result should by a 2 digit number.

So, I fix a two digit number first, say 60.

Then, I multiplied it by some random integer, say 4 and got 240.

Now, 240 is my dividend and 4 is my divisor.

My division problem is:

$\frac{240}{4} =60$

2. The result should be a 3 digit number.

So, I fix a three digit number first, say 600.

Then, I multiplied it by some random integer, say 3 and got 1800.

Now, 1800 is my dividend and 3 is my divisor.

My division problem is:

$\frac{1800}{3} =600$

Solve the following equation for W: 5(w-2)+10=3(2w-9)+5

storchak [24]

Answer:

w=22

Step-by-step explanation:

5(w-2)+10=3(2w-9)+5

1) Use the Distributive Property for 5(w-2) and 3(2w-9):

5w-10+10=6w-27+5

2) Combine alike terms:

5w=6w-22

3) Add a 22 to both sides:

22+5w=6w

4)Subtract 5w from both sides:

w=22

How do you use the product rule to find the derivative of y=x√⋅cos(x)y=sqrt(x)*cos(x) ?

Ipatiy [6.2K]

$y=\sqrt x\cos x\\
y'=(\sqrt x)'\cos x+\sqrt x (\cos x)'\\
y'=\frac{1}{2\sqrt x}\cos x+\sqrt x\cdot(-\sin x)\\
y'=\frac{1}{2\sqrt x}\cos x-\sqrt x\sin x\\

Determine if jk and lm are parallel, perpendicular, or neither j(1,9),k(7,4),l(8,13),m(-2,1)

photoshop1234 [79]

Answer:

"perpendicular"

Step-by-step explanation:

We need to find slope (m) of both line JK and LM

Slope has formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Lets find slope of JK:

$m=\frac{4-9}{7-1}\\m=-\frac{5}{6}$

Lets find slope of LM:

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{1-13}{-2-8}\\m=\frac{6}{5}$

we know if we multiply two lines' slope and get -1, they are perpendicular. Let's check:

$-\frac{5}{6}*\frac{6}{5}=-1$

Hence, they are perpendicular
