Answer:
firstly
we all know that the angles of a triangle they all add up to 180° meaning when you add them all they must give you 180°
88°+33°+L = 180° ( sum of angle in a ∆)
121° + L = 180°
L = 180° - 121°
L = 59°
Step-by-step explanation:
first you you must add all your angles and all equal to 180°
that you add the like terms
than you transpose 121° to the right hand side
Answer:
Total space in the box is 75.2 cm³.
Step-by-step explanation:
Cone:
- It is three dimension shape.
- It has a vertex.
- The slant height of a cone
,
= slant height, r= radius of the base, h= height - The lateral surface area is πrl
- The volume of a cone is
.
The artificial carrot that are cone shaped with a radius 1 cm and a height of 6 cm.
So, the volume of the cone is =

cm³
The volume 1 dozen carrots is = (12×2π) cm³
=75.4 cm³
The volume of the box= The volume of the 1 dozen carrot.
Total space in the box is 75.2 cm³.

Answer:
The probability that at least one is a boy is 0.525
Step-by-step explanation:
P(Baby being a girl) = 0.475
Now, if A is any arbitrary event . Then:
as we know P(A)+ P(not A) = 1
⇒ P(A not happening) = 1 - P(A event happening)
Also, P( baby not being a girl) = P(baby being a boy)
So, P(baby being a boy) = 1 - P( baby being a girl)
= 1 - 0.475 = 0.525
Hence, the probability that at least one is a boy is 0.525
Domain:

As we see in a numerator we have a square, so

is always 0 or more. Now, there are two possibilities:
1.

We divide two numbers, and first one is positive, so the result will be also positive (it canot be 0 in this case) when

. So:

2.

In this case the result wil be 0 (we have ≥ 0 in our inequality, so it will be a solution).

So the solution to this inequality is:
