Answer:
the total cost of the brackets before tax is $89.7
Step-by-step explanation:
The computation of the total cost of the bracket before tax is as follows
Given that
height = 9 feet
length = 10 feet
wall brackets:
48-in costing $12.95
60-in costing $16.95
The distance of brackets from ends is 1 foot
The maximum distance between brackets is 24 inches
Now based on the above information
The brackets are
= 48 ÷ 12
= 4 feet
And
= 60 ÷ 12
= 5 feet
The length of the shelf is 60 inch
Now the 1 could be deducted from each side
= 60 - 2
= 58 in
Now Divide it by 24 inches
= 58 ÷ 24
= 2.41 ~ 3
Finally, The total cost is
= ($12.95 + $16.95) × 3
= $89.7
Hence, the total cost of the brackets before tax is $89.7
addition of signed numbers: -3+2
answer = -1
Answer:
m = 4.5
Step-by-step explanation:
m is the variable for slope (just for validation)
y = 25 + 4.5 (x - 5)
Expand,
y = 25 + 4.5x - 22.5
Collect like terms,
y = 4.5x + 2.5
The slope of the gradient is always the coefficient of x
Therefore, m = 4.5
Hope this helped!! :)
Answer:
7.5
Step-by-step explanation:
25y-15y=10y
10y=75
y=7.5
D = sqrt f
t = cuberoot f (d = ducks, f = fish and t = turtles).
so we need a number f which is a whole number between 1 and 100 and is also a perfect square and a perfect cube. 64 would suit these conditions so we might have
64 fish , 8 ducks and 4 turtles.
