Hello. Good?
Formula for calculating two overlapping sets:
A + B - both + not (A or B) = Total
20 (french) + 20 (german) - 10(both) + Not = 50
40 - 10 + not = 50
30 + not = 50
not = 50 - 30
not = 20
Answer: 20 students do not speak french or german.
Thanks, I hope I have helped.
Answer:
$220.18
Step-by-step explanation:
The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:
In Jayden's case:
- A(n)=$400
- r=12%=0.12
- n=5 years
- k=12 Months
We want to determine the amount Jayden put in the savings account.
Jayden earned $220.18 from doing odd jobs.
Answer:
B
Step-by-step explanation:
Answer:
The fabric needs 196.4 ft²
Step-by-step explanation:
∵ The tent formed formed from 4 faces
two equilateral triangles with side length 7 ft
two rectangles with dimensions 11 ft and 7 ft
∵ Area equilateral Δ = 1/4 S²√3
∵ Area rectangle = L × W
∴ The area of the prism = 2 × 1/4 × (7)²√3 + 2 × 7 × 11
= 196.4 ft²
Note:
If you find the area of the triangle by the rule 1/2 × base × height
∴ Area Δ = 1/2 × (7) × 6 = 21 ft²
∴ Area tent = 2 × 21 + 2 × 77 = 196 ft²
Two answer very closed
