Answer:
You multiply the length and the width to get the area.
Step-by-step explanation: For example if the length was 5 and the width was four the answer would be 20 because 5x4=20
It’s 54 degrees because all the angles are the same
Answer:
10.91
Step-by-step explanation:
.67×8=5.36+5.55=10.91
Answer:
A = 62.35°
A = 62° (Appropriately)
Step-by-step explanation:
To solve for the value of angle A, we employ the COSINE FORMULA.
cos A = (b² + c² - a²) / 2bc
cos B = (a² + c² - b²) / 2ac
cos C = (a² + b² - c²) / 2ab
Where:
A,B,C are the angles of the triangle.
a,b,c are the lengths of the sides
a= 20
b= 16
c= 21
Cos A = (16² + 21² - 20²) / 2*20*16
Cos A = (256 + 441 - 400) / 640
Cos A = 297 / 640
Cos A = 0.464
A = 62.35
A = 62 Appropriately.
Answer:
$46.83
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For saving account A;
P = $1,800
t = 2 years
n = 12 (monthly
r = 3.6% = 0.036
Substituting the values;
A = 1800(1+0.036/12)^(12×2)
A1 = $1934.17
for saving account B;
P = $1,800
t = 2 years
n = 12 (monthly
r = 4.8% = 0.048
Substituting the values;
A = 1800(1+0.048/12)^(12×2)
A2 = $1981.00
The difference will then be
d = A2 - A1
d = $1981.00 - $1934.17
d = $46.83
Therefore, she would have $46.83 more
