Answer: 06.45
Explanation: For this problem, it is essential to know that there are 24 hours in a day. With that said, we take our starting time of 16.45 and since we want to know what time it is 14 ahead (addition), we add the two numbers together.
16.45 + 14 = 30.45
Since there are only 24 hours in a day, and we have exceeded that value, we subtract 24.
30.45 - 24 = 06.45
And that is the time in Brisbane.
Alternatively, you can count time in 12-hour format and convert 16.45 to 4.45 pm by subtracting 12.
Knowing your start time is 4.45pm simply add 14 to that (or change the pm to an and add 2 since 14-12=2).
You will again get 6.45am.
Cheers.
Answer:
17°
Step-by-step explanation:
ΔXWZ = ΔYWZ (they are congruent triangles so ∠XWZ = ∠YWZ)
5x - 8 = 9x - 28
Rearrange and collect the like terms
-8 + 28 = 9x - 5x
20 = 4x
x = 5°
∠YWZ = 9x - 28
sub x = 5
= 45 - 28
= 17°
First lets get the ratio for the avocado and pear trees and work from there
We know there are 5 pear trees for every 2 avocado trees or 5:2
Since we know the total Avocado trees is 18 we can find out how much to multiply the ratio by dividing the total number of trees(18) by the Avocado portion of the ratio (2) 18/2 = 9.
This means to get the total number of pear trees we need to also multiply the pear side of the ratio (5) by 9. 5*9 = 45 pear trees
Now that we know the pear trees we do the same thing with the apple and pear trees to figure out the total apple trees. The ratio of apple to pear trees is 4:3.
Since we know the total number of pear trees is 45 we divide that by the pear side of the ratio (3) to get our multiplier. 45/3=15.
We then multiply our apple side of the ratio (4) by our multiplier (15) to get our total number of apple trees. 4*15=60
Now we know that we have 60 apple trees and 18 avocado trees or 60:18 which reduced is 10:3 apple trees:avocado trees
