Answer:
Rate = 6.56%
Step-by-step explanation:
Principal (P) = $5000
Interest (I) = $6312
Time (T) = 4 years
Rate (r) = ?
This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.
S.I = P(1 + rt)
S.I = simple interest
P = principal
R = Rate
T = Time
6312 = 5000(1 + r*4)
6312 = 5000 + 5000*4r
6312 - 5000 = 20000r
1312 = 20000r
r = 1312 / 20000
r = 0.0656
Rate are calculated in percentage hence we'll multiply it by 100
R = 6.56%
Answer:
196000 tiles.
Step-by-step explanation:
The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.
The tiles are 40 cm.
If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000
So 196000 tiles.
I'm not entirely sure if that's correct, but if it helps that's awesome.
Answer:
16 × π in 2
Step-by-step explanation:
the formula to find the area of a triangle is πr^2, you are given the diameter which equals 2r. so split the diameter in half and plug your number in. π4^2
4^2=16
16xπ
4th option is correct: 16 R5
8 because 18+14 =32 then divide 32 by 2. Then 18-14= 4 then multiply that by 2 and you get 8. 16 -8 = 8
