If an angle is a right angle, its measure is 90.
If an angle measure is 90, the angle is a right angle.
The answer is:
Both statements are true.
This is the biconditional.
An angle is a right angle if and only if its measure is 90°.
Other types of angles:
Acute angle - less than 90°
Obtuse angle - more than 90° but less than 180°.
Straight angle - exactly 180°
Reflex angle - more than 180°
Answer:
166 2/3
Step-by-step explanation:
Let's start by finding out Laine's page per minute rate. We can do this by dividing the number of pages she reads by how long she takes to read them.
25/30 = 5/6 or 0.8333
Now, to find how long it will take her to read 200 pages, let's mutiply the page per minute rate by 200:
200 * 5/6 = 1000/6 or 500/3
Simplify:
166 2/3
I think this is the right number. Hope this helps!
Hello!
The figure is made up of a cone and a hemisphere. To the nearest whole number, what is the approximate volume of this figure? Use 3.14 to approximate π . Enter your answer in the box. cm³
A 12 cm cone with a dome on top of it that has an 8 cm diameter
Data: (Cone)
h (height) = 12 cm
r (radius) = 4 cm (The diameter is 8 being twice the radius)
Adopting:
V (volume) = ?
Solving:(Cone volume)
Note: Now, let's find the volume of a hemisphere.
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 4 cm
Adopting:
If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere
Formula: (Volume of the hemisphere)
Solving:
Now, to find the total volume of the figure, add the values: (cone volume + hemisphere volume)
Volume of the figure = cone volume + hemisphere volume
Volume of the figure = 200.96 cm³ + 133.97 cm³

D) 800 because you can’t get 400 if you didn’t flip the coin over 400 times.. this is because the coin has a 50/50 chance of heads or tails so you double the expectation
