Answer: C (areas B and D)
Step-by-step explanation:
B is 27:36 = 9(3):9(4) = 3:4
D is 24:32 = 8(3):8(4) = 3:4
Answer:
The length is 29 cm while the width is 12cm
Step-by-step explanation:
Given that the length l of a rectangle is 5cm more than twice the width w then
l = 5 + 2w
If the perimeter p of the rectangle is 82cm, recall that the perimeter p of a rectangle is given as
p = 2(l + w)
substituting for l into the equation
82 = 2(5 + 2w + w)
82 = 2(5 + 3w)
Divide both sides by 2
41 = 5 + 3w
41 - 5 = 3w
36 = 3w
Divide both sides by 3
w = 12cm
recall that
l = 5 + 2w
l = 5 + 2(12)
l = 5 + 24
l = 29cm
The answer is A, as I calculated the difference using Pythagora's Theorem. Which I then did 7.6-6.3= 1.29122, which rounds to 1.0 cm^2
Answer:
$2,400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 10000 × 0.06 × 4 = 2400
I = $ 2,400.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 6% per year
for 4 years is $ 2,400.00.
Answer: $4.53
Explanation:
7 dvds cost 31.71 so divide 31.71 by 7
31.71/7 = 4.53
