Answer:
approx. 1/2
part B: 11/24
1/24, explanation in step by step
Step-by-step explanation:
10 /12 is close to 1
3/8 is close to 1/2
Part B:
10/12 - 3/8
10/12 = 20 /24
3/8 = 9/24
20/24 - 9/24 = 11/24
1-1/2=1/2
Part C:
1/2 - 11/24 = 12/24 - 11/24 = 1/24
I think my answer is reasonable because when I subtracted my answer from my estimate, I got a number very close to 0
Answer:
145769 ft²
Step-by-step explanation:
This involves the use of Heron's formula to find the area of the triangle, given the side lengths. We will need to find the semi-perimeter of the triangle, which is half of the full perimeter.
s = semi-perimeter
s = (650+760+450)/2
s = 1860/2
s = 930
Now, using this we put it into Heron's formula to find the area.
A = √((930)(930-650)(930-760)(930-450))
A = √(930(280)(170)(480))
A = √21248640000
A = 145769.1325
A = 145769
The area of the parcel is 145769 ft²
Answer:
If Shawn downloads a movie at a price of $ 2 each, for five movies he should pay $ 10. A percentage of 25% calculated as a sum is required to pay multiplied by 0.25. If for five downloaded movies there is a discount of 25%, it means that at a price of $ 10 he will have a 25% discount, $ 10x0.25 (25%) and get a discount of $ 2.5. That means he saved $ 2.5 if he bought five movies, and would pay $ 7.5.
Answer:
x = 5
Step-by-step explanation:
Since TV bisects (equally divides) EF hence <EKT = 90°
Also <EKT = 5x+65
So
5x+65 = 90
5x = 90-65
5x = 25
Dividing both sides by 5
x = 5
