Answer:
6 cm by 17 cm
Step-by-step explanation:
The area is the product of the dimensions; the perimeter is double the sum of the dimensions.
So, we want to find two numbers whose product is 102 and whose sum is 23.
102 = 1·102 = 2·51 = 3·34 = 6·17
The last of these factor pairs has a sum of 23.
The dimensions are 6 cm by 17 cm.
Answer:
1/7
Step-by-step explanation:
just multiply 1/4 with 1/3
1/4 × 1/3 = 1/7
Answer:
4
Step-by-step explanation:
they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x
Answer:
If they start moving towards each other simultaneously it will take 5 hours to meet.
Step-by-step explanation:
Motorcycle:
Distance = 540 miles
Speed = 48 mph
Time taken = Distance/Speed = 11.25 hours.
Car:
Distance = 540 miles
Time taken = 11.25 -2.25 = 9 hours.
Speed = Distance/Time = 540/9 = 60 mph
If they start moving towards each other simultaneously, they will travel a combined distance of 540 miles and Let the time be t hours.
We have
48 t + 60 t = 540
108 t = 540
t = 540/108 = 5 hours.
If they start moving towards each other simultaneously it will take 5 hours to meet.
