The answer is B.16 : 52.
Let's compare all ratios to 4 : 13.
A. In order to be equivalent to 4 : 13 the ratio should be 8 : 26
4 : 13 = (4×2) : (13×2) = 8 : 26
B. In order to be equivalent to 4 : 13 the ratio should be 16 : 52
4 : 13 = (4×4) : (13×4) = 16 : 52 - Thus, this is the right choice.
C. In order to be equivalent to 4 : 13 the ratio should be 12 : 39
4 : 13 = (4×3) : (13×3) = 12 : 39
D. In order to be equivalent to 4 : 13 the ratio should be 20 : 65
4 : 13 = (4×5) : (13×5) = 20 : 65
Lets x is the amount of money Paul spent
y is the amount of money John spent
<span>Henry spent 3 times as much as paul = 3x
so
</span>John and paul spent $45 altogether: <span>x + y = 45
</span> john and henty spent $65 altogether: 3x+y = 65
solve the equations
3x+y = 65
x + y = 45
---------------subtract
2x = 20
x = 10
x + y = 45
y = 45 - x
y = 45 - 10
y = 35
3x = 3(10) = 30
so
Paul spent $10 (x)
John spent $ 35 (y)
Henry spent $30 (3x)
answer: John spent $ 35
double check:
$ 35 + $ 10 = $45 (<span>John and Paul spent $45 altogether)
</span>$ 35 + $30 = $65 (<span> John and Henry spent $65 altogether)</span>
Answer:
ecd and 25 degrees
Step-by-step explanation:
ecd is dce but is reverse order. CBE angle is 180 degrees(abe is a straight line) minus 155 degrees which is 25 degrees
The average speed for the journey from Llanfyllin to Bala is 14 km/h
Average speed is the ratio of total distance travelled to total time taken. Also, average speed can be given as the average of the different speeds.
Let d₁ represent the distance from Llanfyllin to Vyrnwy and t represent the time taken, since the speed is 12 km/h, hence:
12 = d₁/t
d₁ = 12t
Let d₂ represent the distance from Vyrnwy to bala and t represent the time taken. Since they spent the same time, since the speed is 16 km/h, hence:
16 = d₂/t
d₂ = 16t
Average speed = total distance/total time
Average speed = (d₁ + d₂) / (t + t)
Average speed = (12t + 16t) / 2t
Average speed = 28t / 2t
Average speed = 14 km/h
Hence their average speed for the journey from Llanfyllin to Bala is 14 km/h.

The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg
