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:
2,567 / 4 = 641.75 Hope this helps.
Answer:
boys:girls:teachers
5 : 4 :1
Step-by-step explanation:
75 boys, 60 girls and 15 teachers
boys:girls:teachers
75 : 60 :15
Divide each term by 15
75 /15 : 60/15 :15/15
5 : 4 :1
78.6 = Seventy eight and six tenths.
