A square rotated about its center by 360º maps onto itself at 90°, 180°, 270° and 360° - 4 different angles of rotation.
You can reflect a square onto itself across two diagonals and two segments that connects the middlepoints of opposite sides - 4 different lines of reflection.
If Sajid’s scale is 1:32, the ratio of the length of his model and the lorry is, of course, 1/32. Meaning that the lorry is (32*45)cm long. So, it is 1440 cm. If Chitra’s model uses the scale 1:72, every 72 cm of length of the lorry is 1 cm on the model, meaning that the length of his model is (1440/72) cm= 20 cm
I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.
Answer:
77
Step-by-step explanation:
$2790 is shares equally between 3 committees. each committee would get - $2790 / 3 = $930
If a shirt costs $12 and the Sports Committee gets $930, the committee would get $930 / $12 = 77.5
The committee cannot get half a shirt, so the greatest number of shirt that can be purchased is 77
The answer is D +14 because to negatives make a positive
