The meaning of the options are:
- Acute: an angle between 0 and 90 degrees;
- Straight: and angle of 180 degrees;
- Right: an angle of 90 degrees
- Obtuse: an angle of more than 90 degrees
So, AFB is acute, because it's and angle of 48 degrees, between it's complementary to BFC and they for a right angle.
DFB is obtuse, because it's the right angle DFC plus the angle CFB
Finally, CFD is right (we can only deduce this by looking at the picture)
Answer:
HI LOL
Step-by-step explanation:
Answer:
London is correct
Step-by-step explanation:
We can find the ratio by dividing the ratio of 35:40 by both of the number's greatest common factor. A factor is a number that can be multiplied with another number to get the desired number. The greatest common factor of the two numbers is 5, so dividing both numbers by 5 leaves you with the ratio of 7:8. Hope this helps friend.
For an outdoor event organizers, the expected number of people who will attend is 32700
<u>SOLUTION:</u>
Given, For an outdoor event organizers estimate that 60000 people will attend if it is not raining.
And If it is raining, event organizers estimate that 21000 people will attend.
On the day of the show, meteorologists predicted a 70% chance of rain.
We have to determine the expected number of people who will attend.
Now, number of people = 70% of rain case + 30% of other case.
Number of people = 0.7 x rain case + 0.3 x other case
Number of people = 0.7 x 21000 + 0.3 x 60000
= 2100 x 7 + 6000 x 3 = 32700.
Hence, the expected count is 32700
Answer:
a) x = 4 cm
Step-by-step explanation:
x + 2x + 2x = 20 cm
5x = 20
x = 4 cm
