Answer: c) (-∞, 4) ∪ (5, ∞)
<u>Step-by-step explanation:</u>
There are two lines:
- The left line is between -∞ and 4 with an open dot at 4.
- The right line is between 5 and +∞ with an open dot at 5.
An open dot is represented with parenthesis ( ).
A closed dot is represented by brackets [ ].
<em>Positive and negative infinity are not actual numbers so they are always represented with parenthesis.</em>
<em />
So, the left line is (-∞, 4) and the right line is (5, ∞)
Answer:
197.9
Step-by-step explanation:
The formula for circumference is 2(pi)r and r is the radius
The diameter is two times the size of the radius, so by dividing the diameter by two, you can get the radius
So, r=63/2
r= 31.5
That means that 2(pi)(31.5) is the circumference
2(pi)(31.5) = 197.9 (rounded to the nearest tenth)
m<1=23
m<2=90
m<3=67
m<4=113
m<5=67
the square means it is 90° so 2 is 90°.
all of the angles combined equals 360 so.
360-67-90= 203
since there is a straight line splitting down the middle. m<4=180-67=113
so m<4=113
now you would go 360-67-113-90=90 so
m<1 + m<3 =90
180-90-67=23.
m<1=23
360-67-23-90-113=67
m<3=67
We know that there was a 5% increase from September to October and 5% of we know that there was a 5% increase in boys from September to October and 5% of 1,200 s 60 so 60 boys enrolled in the school in October
