Answer: 20
Step-by-step explanation:
I suppose the figure that you do not include in your exercise is the one that I attached.
Looking at the figure, it is obvious that the angle COA is divided into two angles of 20 degrees each, so the answer would be 20.
Answer:
a)
b)
Dividing both sides by 0.448 we got:
We can appy the exponent in both sides of the equation and we got:
Step-by-step explanation:
For this case we know the following function:
The notation is: x is the weight of the crab in grams, and the output f(x) is the weight of the claws in grams.
Part a
For this case we just need to replace x = 2 gram in the function and we got:
Part b
For this case we know tha value for and we want to find the value of x who satisfy this condition:
Dividing both sides by 0.448 we got:
We can appy the exponent in both sides of the equation and we got:
Rachel and her sister Fran together can paint the living room in hours
Given that
Rachel can paint half of the living room in 1 hour
Fran can paint th part of the living room in 1 hour
Let's assume together they paint the living room in x hours
⇒ together they can paint th part of the living room in 1 hour
By proportions,
⇒+
=
{using operation proportions and addition}
⇒=
⇒x=
⇒ together they can paint th part of the living room in 1 hour
It means, Rachel and her sister Fran together can paint the living room in hours
