Answer:
A
Step-by-step explanation:
● first one:
The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.
STP is one of them so this statement is true.
● second one:
If ST and PT were equal this would be a square not a rhombus.
● third one:
If SPQ was a right angle, this woukd be a square.
● fourth one:
Again if the diagonals SQ and PR were equal, this would be a square.
Step-by-step explanation:
The sum of complementary angles is 90°,
Let 1st be 30x then other is 5x,
30x+5x=90°
➡️ 35x=90°
➡️ x=90°/35=(18/7)°
THUS THE FIRST ANGLE =30*18/7=540/7°
AND SECOND =5*18/7=90/7°

Step-by-step explanation:
Hello!
Oscar is correct, because all the steps he has taken to calculate the final price of the book are right and he has found the final price of the book.
Kim is incorrect because the steps she has taken to calculate the final price are not right, and she will not find the right final price.
YES, they have enough money to buy the book. Simply take all the steps Oscar took and calculate the final price.
28.50 × 30% = 8.55
28.50 - 8.55 = 19.95
19.95 × 10% = 1.995
19.95 + 1.995 = 21.945
This can be rounded to 21.95.
Since $21.95 is LESS than $22.00, they have enough money for the book.
