Answer:
Step-by-step explanation:
1/50 of a mile is the distance the snail goes in 50 minutes. To get an hour, the snail must move for another 10 minutes (60-50=10).
Dividing 1/50 mile by 5 gives us 0.2/50 mile, which would be what the snail travels in 10 mins.
This can be added to 1/50 to give 1.2/50 mile as the answer
OR
You can take 0.2 and times it by 6 (to get 60 minutes from 10 minutes) to give the same answer as above.
Either way, the snail has gone 1.2 miles after the hour has passed.
Answer:
BD = 20 units
Step-by-step explanation:
Given that,
Parallelogram ABCD has diagonal segments AC and BD that intersect at E.
BE = (x+8) and ED = 5x
We need to find the length of BD.
BD = BE + ED ...(1)
We know that the diagonals of a parallelogram bisects each other. It means,
BE = ED
x+8 = 5x
8 = 5x - x
8 = 4x
x = 2
BE = (x+8)
= (2+8)
= 10
ED = 5x
= 5(2)
= 10
Put the values in equation (1).
BD = 10 + 10
= 20 units
Hence, the length of BD is 20 units.
We have to calculate the total cost of the meal. We know that Adam ( A ) and his dad ( D ) share the cost of the meal in the ratio 2 : 3 and that Adam`s dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds<span>. </span>
