We know that the radius of the garden is r = 1.5 ft. use the formula for circumference to find the total length of fencing and round to the nearest tenth:
C = 2(pi symbol)r = 2(pi symbol)(1.5) = 9.4
Since the edging costs $0.75 per foot, find the total cost by multiplying the length of fencing by the cost per foot:
9.4($0.75) = $7
Answer: -2 4/15
Step-by-step explanation: To properly subtract, we need to find a common denominator. We can list the multiples of 3 and 5 to find the common denominator:
3: 3, 6, 9, 12, 15
5: 5, 10, 15
The first common multiple we see is 15.
Calculation:
3 · 3 = 9
9 + 1 = 10
3 1/3 = 10/3
5 x 5 = 25
25 + 3 = 28
-5 3/5 = -28/5
Now to convert into fifteen as the denominator:
-28/5 = -28 x 3/5 x 3 = -84/15
10/3 = 10 x 5/3 x 5 = 50/15
Now to subtract accordingly:
50/15 - 84/15 = -34/15
Final answer: -34/15 (can be reduced to -2 4/15).
Assuming you have 1 chocolate bar, you would have 3/4 of a chocolate bar left since 1/4 x 4 = 1 :)
<span>r' = 4
Since all circles are similar to each other. Such as the radius always being half of the diameter. The ratio between the diameter and the circumference being pi, etc., we have plenty of information to calculate C, d, and r for both circles.
C/C' = 0.75 was given to us. So we know that d/d' is also 0.75. So let's write that equation and solve for d'
d/d' = 0.75
6.0/d' = 0.75
6.0 = 0.75d'
6.0/0.75 = d'
8 = d'
And r' will be half of d', so 8/2 = 4. Therefore r' = 4.</span>
Answer:
x = 0
Step-by-step explanation:
add 23 on both sides and you get x = 0
substitute and the equation still works
