Answer:
1. 425,328 -> 425,330
2. 105,025 -> 105,030
3. 45,527 -> 45,530
4. 35,478 -> 35,480
5. 212,369 -> 212,370
Step-by-step explanation:
000,0<u>0</u>0 the underlined number is the tens place. In order for the tens place to round up the ones place must be 5 or above. If the ones place is lower than 5 you round down to the nearest tens.
In Example:
333,389 you would round up to 333,390 because of the 9 in the ones place.
Now, 333,333 you would round down to 333,330 because of the 3 in the ones place
Answer:
x=39
y=14
Step-by-step explanation:
x+y=53...(1)
x-y=25...(2)
(1)+(2): 2x==78
x=78/2
x=39
then
x+y=53
39+y=53
y=53-39
y=14

Find the measure of angle PET
we know that
The inscribed angle is half that of the arc it comprises.

substitute the given values


step 2
Find the measure of angle PTE
we know that
The sum of internal angles of a triangle must be equal to 180 degrees
In the triangle PET

substitute the given values

step 3
Find the measure of angle STP
we know that
The inscribed angle is half that of the arc it comprises.

substitute the given values

step 4
Find the measure of angle SPT
we know that
----> by supplementary angles


step 5
Find the measure of angle PST
we know that
The sum of internal angles of a triangle must be equal to 180 degrees
In the triangle SPT

substitute the given values


Time taken by Ella is 0.6 hour
<u>Solution:</u>
Lily finished a task in
hour
Ella finished it in
of time Lily took
<em><u>To find: time taken by Ella to finish the task</u></em>
Let "L" be the time taken by Lily
Time taken by Lily = L = 
From given statement,
Time taken by Ella to finish the task is
of time Lily took
Therefore,
Time taken by Ella =
of time taken by Lily

Thus time taken by Ella is 0.6 hour
