V) Find the perimeter of the rectangle whose length is 60m and breadth is 55m
katrin [286]

Answer:

Step-by-step explanation:

l = length

b = breadth

We know the length is twice the breadth, therefore l = 2b

We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:

60 = 2l + 2b

Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:

60 = 2(2b) + 2b = 4b + 2b = 6b

60 = 6b

b = 10 m

Now that we know the breadth we can find the length:

l = 2b → l = 2(10) = 20 → l = 20 m

With a breadth of 10 m and a length of 20 m

ANSWER ASAP!! A movie club charges $10 per month, plus $1.50 per rental. Diego spends no more than $25 per month on movies. Desc
Dafna11 [192]

Answer:

The graph has a closed circle at 10

Step-by-step explanation:

Let

x ----> the number of rentals

The phrase "no more" means "less than or equal to"

so

The inequality that represent this situation is

1.50x+10\leq 25

solve for x

1.50x\leq 25-10

1.50x\leq 10

x\leq 10

The number 10 is included in the solution

therefore

The graph has a closed circle at 10

To solve by completing the square, what needs to be moved in this equation?
Elza [17]

Answer:

To complete the square, we need to have the equation set up like this:

x^2 +4x =9

To do that, we'd need to move the 4x to the left side producing

4x + x^2 = 9

And that can be rewritten as

x^2 +4x =9

So the term that needs to be moved is -4x

Plz help! will mar brainliest.
OleMash [197]

Answer:

From -2<x<-1, the function F(X) is increasing. (B)

Really, it increases all from around -2.5<x<0.5

C is also the second answer, as it increases til around 2.5

It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.

Which means (B) is your answer.

If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
