Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
(24 m)*(4 m) = (5 m)*height . . . . . area is the same no matter which base you use
height = (4/5)*(24 m) = 19.2 m
Answer:
The answer is 15%.
Step-by-step explanation:
The probability that:
- Both treatments are successful:
80% x 90% = 72%
- The first method is a success, but the second one is not:
80% x (1 - 90%) = 8%
- The first method is not successful, but the second one is:
(1 - 80%) x 25% = 5%
- Both treatments are unsuccessful:
1 - (72% + 8% + 5%) = 15%
Answer:
-1 is the only number there that is an integer as all the rest of them are mixed fractions.
Answer:
30
Step-by-step explanation
We have 3 areas for parking and 2 aisles.
Each aisle is 10 ft wide , we have two we have 20 ft for aisles width then total width available for stalls
77 - 20 = 57
And each stall is 19 feet long then 57/19 = 3
And 80 ft long of the lot will permit 10 cars
Then we have each individuals set of stall with 10 parking places
Therefore
3 * 10 = 30
