Answer:
22.8
Step-by-step explanation:
The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.
RV² = RS² +SV²
RV² = 11² +20² = 521
RV = PV = √521 ≈ 22.8
Answer:
47°
Step-by-step explanation:
Since x and 133° are supplementary (meaning they add up to 180°), x + 133 = 180 so that means x = 47°.
Answer:
Average Speed to complete the journey = 80 km/h
Step-by-step explanation:
Given,
The distance between Sydney and Goulburn = 200 kilometer.
Time to complete the journey = 2 hour 30 minutes
Converting the time into minutes -
2 hour 30 minutes
= (2 x 60) minutes + 30 minutes
= 120 minutes + 30 minutes
= 150 minutes
We know, to determine average speed, we have to divide the distance by time.
Therefore, Speed =
Speed =
Speed = 1.33 km/minutes
Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)
Average Speed per hour = 80 km/h
Answer: 3r + 2b = 24
r + 3b = 16
Step-by-step explanation:
Let the red blocks be represented by r
Let blue blocks be represented by b
Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:
3r + 2b = 24
1 red block and 3 blue blocks weigh 16 ounces. This will be:
r + 3b = 16
Therefore, the equation will be:
3r + 2b = 24
r + 3b = 16
Answer:
x<-2
Step-by-step explanation:
x<-2. The line is going to the left of two so it is less then two and the open circle means its only less then not less then or equal to.
