Answer:
800m
Step-by-step explanation:
So one way to answer this would be to write it as a ratio first so you know 4/5 of Chris’s wire = all of Daniels wire so if Chris has 10 ft Daniel has 4/5 of that which is 8 so their ratio is 10:8 which = 5:4. Then Daniel has 1/3 as much as Sarah so we know Sarah has 3x as much so Sarah can be 4x 3 = 12 so your final ratio is 5:4:12 then you have 8 feet of wire and 21 parts total so you do 8/21 and times it by the amount of parts Daniel has which is 4 so 8/21 x 4 is 1.52 ft hope this helps :)
Probability means Possibility. It states how likely an event is about to happen. The probability of an event can exist only between 0 and 1 where 0 indicates that event is not going to happen i.e. Impossibility and 1 indicates that it is going to happen for sure i.e. Certainty.
I'll take a stab at this one. if the number of dice showing a two-digit number = the number of dice showing a one-digit number, then 2 must show a two-digit number and 2 must show a one-digit number
There are 3 two-digit numbers and 9 one-digit numbers on each die
So....the probability is
C(4,2) (3/12)^2 (9/12)^2 =
C(4,2) (1/4)^2 (3/4)^2 =
27/128.

The distance that he has traveled exists 73km 500m.
<h3>What is the distance?</h3>
Distance exists described as the amount of space between two items or the condition of existing far apart. The distance of an object can be described as the complete path traveled by an object.
Given: A motorist travels from town A to town B, which exists 84km apart. He has finished 7/8 of his journey.
To estimate the distance that he has traveled
He covered 7/8 out of 84 km
So, 7/8 × 84 = 73.5 km
The distance he has traveled = 73 km 500 m
Therefore, the distance that he has traveled exists 73km 500m.

Answer:
b= 10.39
c = 20.79
Step-by-step explanation:
a = 60 °
b = 30°
c= 180-(60+30)
c = 180-(90)
c = 90°
Length facing angle a = 18
Let's look for length facing angle b
b/sinb = a/sin a
b/sin 30 = 18/sin 60
b =( 18 * sin30)/sin 60
b = (18*0.5)/0.8660
b = 9/0.8660
b= 10.39
Let's look for c
c/sin c = a/sin a
c/sin 90 = 18/sin 60
c = (18 * sin 90)/sin 60
c =18/0.8660
c = 20.79
