Answer:
1) 28.5ft Squared
Step-by-step explanation:
1/2*b*h
10 *5.7 = 57
1/2 of 57 = 28.5
Answer:
308
Step-by-step explanation:
We are given;
- Money deposited (Principal) as 3850
- Annual rate of interest as 8%
- Period or time = 1 year
We are required to determine the interest accrued;
- We are going to use the formula of calculating simple interest;
- Simple interest = (P × R × T)/100
Where P is the principal, R is the rate while T is the time.
Therefore;
Simple interest = (3850 × 8 × 1) ÷ 100
= 308
Therefore, the money earned simple interest of 308 within 1 year

Answer:
9413
Step-by-step explanation:
Given that :
Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95
Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...
n = sample size
Recall:
n = ((Zα/2 * σ) / Error)^2
Using the formular above, the sample size n can be obtained ;
n = ((1.96 * 99) / 2)^2
n = 97.02^2
n = 9412.8804
n = 9413
