Answer:
A = $1,650.24
Step-by-step explanation:
A = P(1 + r/n)^nt
Where
A = future value
P = present value = $1,600
r = interest rate = 3.1% = 0.031
n = number of periods = 4
t = time = 1 year
A = P(1 + r/n)^nt
= 1,600( 1 + 0.031 / 4)^4*1
= 1600( 1 + 0.00775)^4
= 1600(1.00775)^4
= 1600(1.0314)
= 1,650.24
A = $1,650.24
Surface area of a sphere = <span>4π<span>r2</span></span>
the volume of a sphere= <span><span>43</span>π<span>r3</span></span>
so <span>5000π=<span>4/3</span><span>πr3
</span></span><span>> r^3 = 5000 x 3 / 4
=>
r^3 = 3750
</span>taking cube root on both sides
r=15.53616
hope it helps

350- 175 cats= 175
175 - 140 both pets = 35 dog only students
I guess
Step-by-step explanation:
the empirical probability is 24/30, or 4/5. this is also the desired probability.
a = bx + cx + d Subtract d from both sides
a - d = bx + cx Factor x from bx and cx
a - d = x (b + c) Divide both sides by (b + c)
= x Switch the sides to make it easier to read
x = <span>
