Answer:
Angle(APR) = 43
x = 21.5
Step-by-step explanation:
The given angles are complementary :
So APR + RPW = 90
APR = 43
2x = 43
x = 21.5
If 28 tiles is placed in 7 rows then each row has 4 tiles.
<u>Step-by-step explanation:</u>
The total number of tiles given =28.
The number of rows = 7.
The number of tiles in each row is given by diving the total number of tiles given by the number of rows.
No of tiles in each row= 
.
No of tiles in each row = 
.
No of tiles in each row = 4.
Note: You can replace the values according to the given values.
98 98/100 because you move the decimal point over 2 times
T= number of minutes
Multiply 5 liters by number of minutes (t), then add the 17 liters already in the tank. This totals 72 liters or more.
17 + 5t ≥ 72
subtract 17 from both sides
5t ≥ 55
divide both sides by 5
t ≥ 11 minutes
ANSWER: Laura could add water for 11 minutes to be sure the tank has 72 liters or more.
