Answer:
Shane must have collect 911 cans.
Step-by-step explanation:
Assume;
Cans collected by Shane = x
So,
Cans collected by Abha = x+178
Inequality
Cans collected by Shane + Cans collected by Abha ≥ 2,000
x + x + 178 ≥ 2,000
2 x ≥ 2,000 - 178
2 x ≥ 1,822
x ≥ 911
Shane must have collect 911 cans.
Answer:
Intrest Income= 434.87, Account Balance= 4434.87
Step-by-step explanation:
To solve this problem, we can use the exponential growth formula.
To find the decimal for 3.5%, divide it by 100. 3.5/100=0.035
The formula is F(T)= A(1+R)^T
A= Initial Amount
R= Regrowth rate
T= Time period
Now insert everything,
F(T)= 4000(1+0.035)^3
Now solve the problem,
4000(1.035)^3 (First do the exponent, then multiple)
1.035^3= approx 1.108717875 or 1.11
4000*1.108717875=
Our account balance is 4434.87, after 3 years.
4434.87-4000 will give us the interest income after three years,
The interest income is 434.87.
Answer:
15x^2 - 14x - 8 = 0.
Step-by-step explanation:
(x - 4/3)(x + 2/5) = 0
Converted to integer values by multiplying the first bracket by 3 and the second by 5:
(3x - 4)(5x + 2) = 0
Expanding the brackets:
15x^2 + 6x - 20x - 8 = 0
15x^2 - 14x - 8 = 0.
Area of a circle = PI x r^2
you state pi = 3.19 ( it is usually 3.14, if it is a typo see below )
diameter = 14cm
r = 1/2 the diameter, so r = 7 cm
area = 3.19 x 7^2
area = 3.19 x 49 = 156.31 square cm
( if PI = 3.14, area = 3.14 * 49 = 153.86 square cm)
You have to add fractions less than 1/4 i think
