Answer:
The interest rate is 5%.
Step-by-step explanation
The appropriate formula to use here is as follows:
i = simple interest = p*r*t.
Let's solve this for i: divide both sides of the equation by p*t:
i
------ = r
p*t
Subbing $412.5 for i, $750 for p and 11 yrs for t, we get:
$412.50
-------------- = 0.05.
($750)(11)
The interest rate is 5%.
Answer:
5a. 4w+24≤100
5b. Dimensions=31ft x 19 ft
Area = 589ft²
Step-by-step explanation:
l=w+12
p=2l+2w
p=2(w+12)+2w
p=2w+24+2w
p=4w+24
The farmer has 100ft of fencing, so maximum that the perimeter (p) can be is 100, meaning (4w+24) has to be less than or equal to 100:
4w+24≤100
For the largest possible perimeter, all 100 of fencing will be used, so allow 100 to be equal to 4w+24)
100=4w+24
4w=76
w=19ft
l=w+12
l=19+12
l=31ft
The dimensions are 31ft x 19ft.
Area=lw
=31*19
=589ft²
Hello,
if we use Heron's formula:
p=(7.2+5.9+11.2)/2=12.15
Area=√(p*(p-a)(p-b)(p-c))
=√(12.15*(12.15-7.2)(12.15-5.9)(12.15-11.2))
=√357,09609375
=18,896986366878714557972599553433≈18.90
So i suppose Answer=D (with an error of 0.01)
B (11*11)
D (12*12)
E (15*15)
Answer:
Hi, there your answer is
Step-by-step explanation:
Let's solve for y.
3x−6y=24
Step 1: Add -3x to both sides.
3x−6y+−3x=24+−3x
−6y=−3x+24
Step 2: Divide both sides by -6.
−6y
/−6
=
−3x+24
/−6
y=1/2x-4
Hope this helps :)
