Answer:
The area of the printed picture is 172.5 square inches.
Step-by-step explanation:
Since a picture is to be printed onto a sheet of paper with dimensions of 81/2 x 11 inches, and a margin of 1 1/2 inches is to be left on all sides of the picture, to determine what is the area of the printed picture the following calculation must be carried out, knowing that the area of a rectangle is equal to the base multiplied by the height:
81/2 = 40.5
1/2 = 0.5
40.5 - 1.5 x 4 = 34.5
11 - 1.5 x 4 = 5
34.5 x 5 = 172.5
Therefore, the area of the printed picture is 172.5 square inches.
Answer:
1) Numerical expression that represents the area Sabrina painted the first weekend:
2) Area that Sabrina painted the first weekend:
3) How much more of the total area she painted the first weekend than in the subsequent 3 weekends:
Explanation:
<u>1) Data:</u>
- a) Total area that Sabrina has to paint: 1,600 ft².
- b) Every weekend she paints half of the area that remains to be painted
- c) Number of weekends Sabrina paints: x
- c) Every wee
<u>2) Write a numerical expression that represents the area Sabrina painted the first weekend:</u>
- Half of 1,600ft² = (1/2) × 1,600 ft² =
<u>3) Find the area that Sabrina painted the first weekend.</u>
Compute:
- (1/2) × 1,600ft² = 1,600ft² / 2 = 800 ft²
<u>4) Find how much she painted after four weeks. </u>
- Second weekend: (1/2) 800ft² = 400ft²
- Third weekend: (1/2) 400ft² = 200ft²
- Fourth weekend: (1/2) 200ft² = 100ft²
Total area painted during those three weekends:
- 400ft² + 200ft² + 100ft² = 700ft²
<u>5) Find how much more of the total area she painted the first weekend than in the subsequent 3 weekends.</u>
This is the area she painted the first weekend, 800ft², less the area she painted the subsequent 3 weekends, 700ft²:
Answer:
C' (4, - 6 )
Step-by-step explanation:
4 units left means subtracting 4 from the x- coordinate
3 units down means subtracting 3 from the y- coordinate
C (8, - 3 ) → C' (8 - 4, - 3 - 3 ) → C' (4, - 6 )
Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27
