Answer:
approximate 23.590 feet
Step-by-step explanation:
tan 65° = x / 11 = 2.145
x = 11 x 2.145 = 23.595
Answer: Area = 6.64966
Step-by-step explanation:
Answer:
a. 20
b. $15
Step-by-step explanation:
We can say that represent the 30-day period, then we can write the next equation:
Finding the , we find the number of 30-day periods until the value of the cards will be equal, then:
Then is needed a 20 30-day periods to have the cards with equal value.
Now to know the walue of each card we have:
Then each card will have a value of $15
Answer:
Option 3. (2π + 40) mm².
Step-by-step explanation:
Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.
Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²
= (4 + 8)/2 × 4 + 4² + (1/2)×π×4
= 24 + 16 + 2π = (2π + 40) mm²
Therefore option 3. (2π + 40) mm².
First semester: 2:7
Second semester: 5:4
5*15 = 75
15*4 = 60
75:60 (art class - gym class)
2:7
2*15 = 30
7*15 = 105
There were 30 students in art class and 105 students in gym class second semester.
