Simplify 9b-5b ?? Pls help

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

9b-5b

Factor out a b

b(9-5)

b(4)

Answer 2

Answer:

Answer:

9b - 5b = 4b

Step-by-step explanation:

so to simplify this you are simply just going to subtract the 5 from the 9. Don't worry about the variable right now.

9 - 5 = 4

add the variable back in to each number, 9b - 5b = 4b

in an equation y varies directly as x varies. if y = 55 when x = 22, what is the value of x when y = 85?

Answers

Answer:

x=34

Step-by-step explanation:

If you put Y and X into a ratio then it will be

5:2

because since their GCF is 11, then we will have to divide both of the numbers by 11.

If y=85 then that means that it was multiplied by 17. If we want them to stay within the same ratio, then we will have to multiply X (2) by 17.

That will get you 34.

Gwen is filling a pool. She begins to wonder how fast the water is flowing into the pool. Which unit rates would be reasonable for Gwen to use to describe how fast the pool is filling with water? Select each correct answer. gal/h cm3/min L/h in3/s

Answers

I just took the test and the answer was gal/h and L/h, the reason it's not cm3/min or in3/s is because you can't measure water using centimeters or inches.. But you can measure water with Gallons and Liters :)

Answer:

Gallons per hour & liters per hour

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

A (-5 , -1)

B (-2, 3)

C (6, -3)

Perimeter = ?

Formula

$d = \sqrt{(x2 - x1)^(2) + (y2 - y1)^(2) }$

distance AB $d = \sqrt{(-2 + 5)^(2) + (3 + 1)^(2) }$

$d = \sqrt{(3)^(2) + (4)^(2) }$

$d = √((9 + (16) )$

$d = √(25)$

d = 5

Distance BC $d = \sqrt{(-3 - 3)^(2) + (6 + 2)^(2) }$

$d = \sqrt{(-6)^(2) + (8)^(2) }$

$d = √(36 + 64)$

$d = √(100)$

d = 10

Distance AC $d = \sqrt{(-3 + 1)^(2) + (6 + 5)^(2) }$

$d = \sqrt{(-2)^(2) + (11)^(2) }$

$d = √(4 + 121)$

$d = √(125)$

d = 11.2

Perimeter = 5 + 10 + 11.2

= 15 + $√(125)$

Consider a situation in which P(X) = and P(Y) = . If P(X and Y) is = , which best describes the events?They are independent because P(X) · P(Y) = P(X and Y).
They are independent because P(X) + P(Y) = P(X and Y).
They are dependent because P(X) · P(Y) = P(X and Y).
They are dependent because P(X) + P(Y) = P(X and Y).

Answers

Answer:

They are independent because P(X) · P(Y) = P(X and Y).

Step-by-step explanation:

Two events are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. This means that the probability of both events happening is equal to the product of the probabilities of each event happening individually.

In the given situation, we have:

P(X) = 1/2

P(Y) = 1/2

P(X and Y) = 1/4

If we calculate the product of P(X) and P(Y), we get:

P(X) · P(Y) = 1/2 · 1/2 = 1/4

This is equal to P(X and Y), which means that the events X and Y are independent.

P(X) + P(Y) = P(X and Y) is not a necessary condition for independence. For example, the events of flipping a coin and rolling a die are independent, but P(X) + P(Y) ≠ P(X and Y).

Therefore, the best description of the events is that they are independent because P(X) · P(Y) = P(X and Y).

Answers

Translation the graph of the function $y=f(x)$ a units to the right gives you the function $y=f(x-a).$

If the graph of the function $f(x)=3^x$ is translated 6 units to the right, then the function becomes

$g(x)=f(x-6)=3^(x-6).$

Answer: correct choice is A

A is the answer

The distance between City A and City B is 500 miles. A length of 1.9 feet represents this distance on a certain wall map. City C and City D are 3.42 feet apart on this map. What is the actual distance between City C and City D?

Answers

The solution is, Actual distance between point C and D is 900m.

What is ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

here, we have,

given that,

The distance between City A and City B is 500 miles.

A length of 1.9 feet represents this distance on a certain wall map.

City C and City D are 3.42 feet apart on this map.

Let, x be the actual distance between point C and D

Using ratio method,

1.9 : 500

3.42 : x

Now, we get,

1.9/500= 3.42/x

i.e. 3.42/x = 0.0038
