If we know that one of the children MUST be a boy, than I believe it is a fifty percent chance that the other child would be a boy. You have two things that can happen— one being the child being a boy and the other is it being a girl. Therefore, the answer should be 50%.

Two angels are supplementary. The measure of the large angle is four more than three times the measure of the small angle. Find
sashaice [31]

Answer:

The measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

Step-by-step explanation:

Supplementary angles are two angles whose measures add up to 180° .

Let

Small angle = x

Large angle = y

x + y = 180°.... Equation 1

The measure of the large angle is four more than three times the measure of the small angle

Hence: y = 4 + 3x

We substitute 4 + 3x for y in Equation 1

x + 4 + 3x = 180°

4x + 4 = 180°

4x = 180° - 4

4x = 176

x = 176/4

x = 44°

Solve for y

y = 4 + 3x

y = 4 + 3(44)

y = 4 + 132

y = 136°

Therefore, the measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

A mule dear can 1/4 of a mile in 25 seconds. At this rate, what expression can be used to determine how fast a mule deer runs in
Naddika [18.5K]
We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144
Now, we can multiply 144 by 14 or .25 since we are trying to find per hour.
144×.25= 36
36h
H being the hours you're trying to find. It runs 36 miles per hour.
